Description of the invention: [Technical field to which the invention pertains] The present invention relates to the detection of grounding, and more particularly to an operator working on a production line, whether or not an antistatic wrist strap or a similar grounding mechanism is worn. A detection device that avoids electrostatic hazards. [Prior Art] How to avoid electrostatic damage and cause the failure of important processes or the loss of expensive raw materials is still a headache for high-tech semiconductor and electronics industries. Good grounding is the most important way to avoid electrostatic hazards, but even in today's technological developments, it is still difficult to ensure good grounding in the production process. In a typical production work environment, there are usually multiple production lines, and one production line often contains multiple stations for different production or assembly steps. In order to avoid static damage to the electronic components, equipment, tools, or semi-finished products used in the workstation, the operator is usually required to wear an anti-static wrist strap, and the ground will usually be laid. An electrostatic floor mat is placed on the workstation's desktop with an anti-static table mat. As shown in FIG. 1a, the floor mat 10, the table mat 20, and the wrist strap 30 of the workstation are typically connected to a common point ground 40 of the workstation by a ground line. The common grounding 40 is usually a metal piece or a metal wire fixed at a suitable position on the workstation, and is covered with a plastic outer casing (only the grounding 201005301 line between the wristband 30 and the common ground 40 is drawn). The common point grounding 40 of each workstation of a production line is usually connected in series or in parallel, and finally collected together with the equipment ground or earth ground connection (for the sake of simplicity, this part) Not shown in the figure). With such an arrangement, static electricity carried or accumulated on the worker standing or sitting in front of the workstation can be grounded via a wristband, a table mat, or a floor mat, a common ground of the workstation, grounding of the building equipment, or otherwise independent. The earth ground leaks to the earth to eliminate the electrostatic hazard of (4). The aforementioned grounding architecture is basically effective and has been around for a long time. However, there are the following shortcomings in practical applications. First, such a grounding structure is a measure of whether the wristband mat or the mat has a monthly b-force that is reliably connected to the common grounding defect. For example, the grounding wire between the wristband, the table mat, or the floor mat and the grounding point of the common point may be rusted (4) (4), or the wristband and the common point may be disconnected due to the relationship between Yang Zuo. In addition, because the grounding wire of the wristband is usually connected in the form of a pluggable plug and a grounded joint, the worker must pull the plug away when leaving the workstation (eg toilet or meal). But the ankle strap is still worn on the wrist.), or take off the entire wristband and place it on the work table. Wait until you return to the workstation and then plug the plug back or put the wristband on. In the case of frequent occurrences, the staff forgot to insert the plug or put on the wristband, and sometimes the staff knew that they would wear the wristband, but they did not wear it because of trouble. Therefore, the static electricity accumulated in the red body on the worker's body cannot be eliminated through the wristband 201005301. It is likely to damage the finished product or semi-finished product during assembly and production, even expensive electronic equipment. For the above problems, the inventor of the present invention proposed a wireless detecting device for the staff on the production line whether to wear an antistatic wrist strap or a similar grounding mechanism (hereinafter referred to as the previous application, China Invention Patent Application No. 96137674, The application was filed on October 8, 1996. The representative figure is reproduced in the lb diagram. As shown, the detection device 100 is a stand-alone device with a microprocessor circuit 200G as its core. There are three external electrical connections, one is the connection to the mains via a power cable or an external power supply (such as a transformer used in a notebook computer), except that the microprocessor circuit 200 is provided via a power supply unit 500. In addition to the DC power required, it is also important to obtain the grounding 60 of the mains. The other is connected to the equipment grounding or earth grounding (hereinafter collectively referred to as "earth grounding") 50 via an interface 120, which can be achieved through the common grounding 40 of the workstation, or as shown in the figure. The third connection is via the interface 110 to the two wires 31, 32 in the grounding wire of the wristband 30. One end of the wire 31 is connected to the earth ground 50 inside the detecting device 100, and one end of the wire 32 is connected to the mains ground 60 via the microprocessor circuit 200. The other ends of the wires 31, 32 are respectively connected to the two conductive sheets contained in the wrist band 30. The wristband 30 typically has an insulative housing with a conductive sheet placed inside the insulative housing to contact the wrist skin 70. Therefore, when the staff wears the wristband 30 normally, as shown by the dotted line in Figure 2a, 201005301, 'from the mains ground 60, the ground, the ground 5, the wire 3i, the person's skin 70, the wire 32, and then through the micro-processing The circuit is said to constitute two (10) ways. The main function of the microprocessor circuit _ is whether the η loop has an appropriate resistance. Other details are not described here. The above-described prior application of the present invention has the following further improvements. First of all, the wireless device is only suitable for the connection system with two wires, but the city

In addition, the wireless device can only provide the function of the measurement, but can not provide the protection of the static electricity more actively. For example, if the connection between the wireless debt measuring device and the common grounding 4〇 or the grounding ground 5因 is interrupted for some reason (as shown by X in the figure), even if the staff wears an antistatic wrist strap, The wireless_device will still issue a warning, and the red-handed personnel will not be able to work until the grounding obstacle is repaired. The so-called "active protection of static electricity" means that since the relevant grounding mechanism is connected to the wireless debt measuring device, if the wireless detecting device can provide additional grounding, the staff can be grounded from the common point. 40 or earth ground 5. The connection between the two is broken. Correction 1 means that every - wireless device requires an external power supply (such as a laptop used in laptops), resulting in an increase in cost. SUMMARY OF THE INVENTION The present invention proposes a system for detecting whether a worker on a production line wears a 201005301 anti-static wrist strap or a similar grounding measure, and a serial connection of these detecting devices. The main feature of the detection device is the use of wireless energy transfer and sensing mechanisms (such as infrared) to detect if the worker is in front of the workstation. In the case of a staff member, the detecting device simultaneously detects whether the worker has formed a circuit with a suitable resistance via its grounding mechanism (such as a wristband). If the resistance value of the circuit is found to be abnormal (for example, the wristband is not worn) or the wrist strap is not properly grounded (for example, the wrist strap is connected to the common point, but the 1ΜΩ resistor in the grounding wire is broken or shorted). A warning signal will be sent. Compared with the prior application, the present invention further proposes a special internal electrical connection mode, and the way in which the cable is connected in series to provide power and grounding can be achieved: (1) Suitable for single wire and double wire at the same time. The detection of the grounding mechanism, (2) the provision of grounding backup, the loss of static electricity is not lost due to the single-point and grounding disconnection, and (3) the extension of the grounding is provided, so that the grounding is not pre-arranged. Covers each workstation, (4) supports the power required by all single-connected grounding devices with a single external power supply, without the need for an external power supply for each detection device, and (5) for serial connection The cable also provides two-way data exchange, which greatly simplifies the network connection cost of multiple detection devices. The above and other objects and advantages of the present invention will be described in detail with reference to the accompanying drawings and claims. It is to be understood that the appended drawings are purely illustrative of the spirit of the invention and are not to be construed as a limitation of the scope of the invention. For the definition of the invention, please refer to the attached patent application. [Embodiment] Fig. 2a is a schematic view showing the electrical connection of the detecting device according to the first embodiment of the present invention. The figure includes two devices of the present embodiment, including at least two wires 7 (Π, 702, 7 〇〇 phase ratio, one of the measuring devices 100 and at least included - DiDoo & 111 匕 3 - wire 71 71 712 cable 71 〇 and 0 卜 卜 power supply 11 _ connection. And the former request - like, the device _ is - a microprocessor circuit 200 core The stand-alone application should be clearly different from the previous application. It should be noted that the former application of the first embodiment also has an interface similar to the interface 150. And the external power supply, but for the sake of simplicity is not drawn. In Figure 2a, in order to clearly illustrate the way of electrical connection, 0 is particularly close to the details of the interface 150. Compared with the previous application, the debt test The device 〇〇 additionally has an interface 15 for engaging the cable 700. The two interfaces 150 are connected to the wires 701 (or 711) and the wires 7〇2 (or 712) are inside the detecting device 100. Is connected together. Connected to the wire 7〇2 (or 712), in the detection device 1 The inside is further connected to the power supply unit 5. The wire 701 (or 711) is connected to the microprocessor circuit 200 and the interface 120 inside the detecting device 1 . The two interfaces 15 〇70 is the same 'no limit' which must be used to connect the front and rear level detection device 201005301 to 100, or the external power supply 600. The external power supply 600 is connected to the mains and the mains ground 60 is removed. The power supply 600 transmits AC or DC power through the wires 712 of the cable 710 and the wires 702 of the cable 700 to the station 100. The power of the wires 712, 702 is passed through each of the wires. The power supply unit 500 of the detecting device 100 provides the DC power required by the microprocessor circuit 200. At the same time, the external power supply 600 transmits the mains ground 60 through the wires 71 of the cable 710 and the wires 701 of the cable 700. The station is provided to each of the serial detection devices 100. Although only two detection devices 100 are shown in the figure, two or more detection devices 100 (usually mounted on the same connection method) Each workstation on the production line can also be connected in series by cable 700, and then the external power supply 600 is connected to any one of the debt measuring devices 100 by cable 710. By way of this connection, this The invention uses a single external power supply 600 to simultaneously push the detection device 100 of each work station on the production line, thereby saving considerable cost compared with the previous application. As can also be seen from the figure, the detection device 100 can also be separately used. For use, it is not necessary to connect other detecting devices in series, but when used alone, the detecting device 100 needs to be connected to an external power supply 600 by a cable 710. Compared with the dotted line in FIG. 1b (that is, the microprocessor circuit 200 of the previous application is used to detect whether the wristband is correctly worn and passed through the earth), this embodiment is the detecting device 100. The inner loop constitutes a loop from the joint of the guide 11 201005301 line 701 and the interface 120, via the interface 110, the wire 31, the skin 70 of the worker, the wire 32, and then back to the wire 701 via the microprocessor circuit 200. Interface 120 has a common contact. One of the main functions of the microprocessor circuit 200 is to detect whether the loop has an appropriate resistance, or to detect the resistance seen between the conductor 31 (also the interface 120) and the conductor 32. Does the staff wear a wristband 30? When the detecting device 100 is used alone (for example, only the detecting device 100 located in the upper half of the cymbal in FIG. 2a), the static electricity carried by the worker may leak from the following places: (1) connected via the interface 120 itself. Ground ground 50, (2) mains ground 60 via external power supply 600 of cable 710. In other words, the present invention provides a grounded backup mechanism. When the connection between the detecting device 100 and the grounding ground 50 (with or without the common grounding 40) is broken, the static electricity carried by the worker can still leak to the commercial ground 60 via the wristband 30. When the detecting device 100 is used in series (take the detecting device 100 located in the lower half in FIG. 2a as an example), the static electricity carried by the worker may leak from the following places.

In other words, such a series connection provides an extremely rich grounding backup. It is assumed that N detecting devices 100 are connected in series in the above manner, which means that each detecting device 100 has N 12 201005301 contacts at the same time as the grounding ground 50. As long as one of the contacts (the connection of one of the detecting devices 100 to the grounding ground 50) is still active, all of the N detecting devices are connected to the grounding ground 50. Even if all of the N detecting devices 1 are disconnected from the grounding ground 50, all of the detecting devices 100 can still discharge static electricity through the mains ground 60. As for the breakage of the twisted wires 700, 710, since the cable 7〇〇71〇 is also responsible for the transmission of electric power, the breakage of any one of the cables 700, 71〇 causes one or more detecting devices to lose power. Stopping the operation, this situation will immediately cause the attention of the operator and take the repair. Other applications of the present invention can be extended from the above embodiments, for example, (1) only one of the plurality of detecting devices 100 connected in series is directly connected to the grounding ground 50. It is equivalent to "extending" the grounding ground 50 by using a plurality of detecting devices 100 connected in series, without setting the grounding ground 50 at each workstation. If the interface of the test device 1 is added with other interfaces, then the "extended" earth ground 50 can be shared with other devices, so the cost of grounding can be greatly reduced; (2) since the mains ground 60 is also effective. Grounding, therefore, the plurality of debt measuring devices 1 串 that are connected in series may not be connected to the grounding ground 50, but rely on the mains ground 60 and its extension through the series to leak static electricity, which is in the absence of the earth The grounding 50 environment is very convenient. As in the previous application, the interface 110 between the grounding wire of the wristband 30 and the detecting device 1〇〇 can be dynamically plugged and separated. For example, one end of the grounding wire 13 201005301 is a plug, and the detecting device 100 is For a corresponding socket. In other embodiments, the interface between the grounding wire of the wristband 30 and the detecting device 1〇〇 can also be fixedly connected. Similarly, the interface 12〇 and the earth ground 5〇 connection may be fixed or dynamically connected. The foregoing embodiment provides only the detection of the wristband 3〇, and the floor mat 桌 and the table mat 20 in Fig. 1 are still connected to the common ground. Fig. 2b is a schematic view showing the electrical connection of the detecting device according to the second embodiment of the present invention. In the present embodiment, as shown in the figure (for the sake of simplicity, the ground pad 1 〇, the external power supply 600, the grounding ground 50, etc. are omitted), the wire 2 of the grounding pad of the table mat 2 is passed through the interface no. The wrist straps are connected in series (the interface 13〇 can be fixed or dynamically plugged) to form a larger loop (shown by a broken line in the figure). The microprocessor circuit 200 is capable of simultaneously detecting the table mat 2 and the wrist strap 3〇. In the same way, it can be easily inferred how to connect the ground 10 or other grounding wires to the grounding mechanism with two wires as well. Therefore, the detecting device can be used in the same way as the detection of the wristband 30, at the same time, the grounding pad 1 〇, the table mat 2 〇, or other grounding wire also has a wire grounding mechanism. Detection. The microprocessor circuit 200 determines whether there is a problem with the wristband, the floor mat, the table mat, etc. connected in series by detecting the loop resistance. However, when the loop resistance is abnormal, the wristband cannot be judged. Table mats, or floor mats. The third embodiment shown in Fig. 2c is a circuit in which the wristband 3's and the table mats 2' are respectively formed into 14 201005301 (shown by broken lines in the figure), so the microprocessor circuit 200 can respectively pair the wristbands 30. The table mat 20 is detected. Similarly, how to ground the ground pad 10, or other grounding wires with the same two wires, and the grounding mechanism are also included in the detection, so it can be easily inferred, so I won't go into details. Please note that the microprocessor circuit 200 detected by this parallel method and the microprocessor circuit 200 detected in series are not identical, but once the microprocessor circuit 200 detected in series is known, it can be very It is easy to infer that the microprocessor circuit 200 is detected in parallel. In some embodiments, wristbands, table mats, floor mats, and even other grounding mechanisms that require detection may be used, some in series and some in parallel. In addition, more than one wristband, table mat, and floor mat can be detected. Note that the aforementioned ground backup function is fully applicable, whether in series or in parallel with one or more other grounding mechanisms. For the sake of simplicity, the present specification is to detect the microprocessor circuit 200 in series, and consider only one wristband 30 as an example to illustrate the details of the detector 100. Figure 3a is a functional block diagram of a microprocessor circuit of a detecting device in accordance with an embodiment of the present invention. It is noted that the Vin in the figure is the power supply unit 500 of the detecting device 100 that converts the voltage of the commercial power or the external power supply to the DC voltage to which the microprocessor circuit 200 is applied. As shown, the microprocessor circuit 200 includes a comparison amplification unit 210, which is primarily comprised of more than one operational amplifier. In the figure, the variable voltage of the series 15 201005301 and R 1 ΤΛ v , R2 can also be a part of the comparison amplifying unit 210: it is additionally drawn for the sake of explanation. The operational amplifiers of the variable resistors R1 and R2, which are arranged in the comparatively magnified early element, are compared with whether the resistance value of the transistor which is guided by the wire 32 is smaller than the first resistance value which is composed of ^ and illusion. Between the second resistance value of the big one, to judge the staff is ❹ ❹ If the guardian does not call the wristband 3G, or the wristband 3〇 ground wire has _ or break, the resistance value of the loop will be greater than the second resistance. Or 'If the staff member wears a wristband 3〇 and the wristband 30 and its secret line are both positive (four), the electric difficulty of the circuit is not cut, and the resistance value is lower than the first resistance value. When the resistance value of the circuit is greater than the first When the two resistance values are smaller or smaller than the first resistance value, the comparison amplification unit 21G triggers the operation of the processor unit (4). The present invention also has some embodiments that include only the variable resistor Ri (i.e., the variable resistor R 2 in the figure is omitted), and these embodiments therefore only detect if the resistance value of the loop is smaller than the resistance value of the variable resistor. There are also some embodiments that use a fixed resistor, but the advantage of using a variable resistor is that it can be used for loops, and (for example, a circuit including only a wrist strap, or a circuit including a wrist strap, a special series, etc.) ) and dynamically adjust. The adjustment of the variable resistor Hanhan 2 can be performed by an adjustment knob exposed to the outer casing of the detecting device or by a control panel on the outer casing of the detecting device. Processor unit 220 is the core of the debt testing device. It is basically composed of a single chip, which has built-in storage control firmware program 201005301 body, random access memory, oscillator and clock circuit, input and output lines, and the like. The details of those familiar with single-chip design are not necessary to repeat. After being triggered by the comparison amplifying unit 210, the processor unit 220 drives the warning unit 230 to issue an alert signal to remind the staff to wear the wristband or prompt the manager for processing. The alert unit 230 includes one or more lights, for example, that utilize light emitting diodes (LEDs). Provide visual alerts by lighting or flashing these lights. The alert unit 230 may also include circuitry such as a horn 0 or a buzzer to provide an audible alert. The aforementioned visual and audible warnings may alternatively be implemented or combined. The alert unit 230 may further include a relay circuit to trigger an external alarm or the like. After the condition of the trigger processor unit 220 disappears, the processor unit 220 drives the alert unit 230 to stop issuing the alert signal. Or the detection device has a control button or a control panel on the outer casing to manually turn off the warning signal. The function of the person detecting unit 240 is to detect whether a worker is located in front of the © workstation (that is, in front of the detecting device), and to generate a result (for example, when a person is detected or exists, a person appears The signal, the detection of the person leaving or not presenting another person leaving the signal) is immediately transmitted to the processor unit 220. Thereby, the processor unit 220 can determine whether to issue the fault value according to the detection result of the leakage loop when it is determined that the worker is located in front of the workstation (for example, the person has not received the signal further after receiving the signal). Warning. Therefore, when the worker has to leave the workstation and detach the wristband 30, 17 201005301 or separate the grounding wire of the wristband 30 from the dynamic plug interface 110 (see Figures 2a, 2b, 2c) of the detecting device, Although the processor unit 220 finds that the resistance value of the loop is abnormal (because it is in an open state), the processor unit 220 does not instruct the alert unit 230 to issue an alert signal because the person receives the leave signal. However, when the person detecting unit 240 detects that a person appears, the processor unit 220 starts to drive the warning unit 230 according to the result output by the comparing and amplifying unit 210, so as to prevent the worker returning to work to forget to wear the wristband. 30 or forget to re-plug the ground wire of the wristband 30 back to the dynamic plug interface 110. Please note that the person detecting unit 240 only provides the detection result of whether or not a person appears or leaves, and the judgment is still performed by the firmware of the processor unit 220. In order to avoid misjudgment and to give the staff time to locate, the firmware of the processor unit 220 usually stops driving the warning unit 230 according to the result output by the comparison amplifying unit 210 when the person is found to leave; but after the staff reappears The warning unit 230 is driven to resume the result of the comparison of the output of the unit 210 by a period of time (e.g., 5 seconds). The method for detecting the presence of a person by the person detecting unit 240 is mainly active or passive. Figure 3b shows a schematic diagram of an active personnel detection unit. As shown in the figure, the active person detecting unit 240 has a wireless energy transmitting source, such as the infrared LED 241 or the radar shown in the figure, which can be sent out within a limited range (for example, toward the position of the worker).

還需要具有一感應從工作人員身上反射回來的能量感測器 (sensor )，例如圖中所示的紅外線接受器242。在吾人曰常 生活中，這種主動式的偵測技術已經有許多類似的應用，因 此發送源、感測器這些元件和相關電路都已經有許多揭露可 以依循或是現成的模組可以採用。例如主動式的紅外線偵測 在自動沖水的衛浴設備中很常見，採用超音波者則可以在汽 車的倒車雷達找到類似的應用。如圖所示，處理器單元220 〇 的一個輸出控制一電子開關243以開啟或關閉紅外線LED 241的點亮。紅外線接受器242的偵測結果則傳送給處理器 單元220的一個輸入。 對本發明而言，主動式的偵測具有一定實效，但是工作 站前常會設有工作人員的座椅，人員偵測單元240並不易區 別工作站前是工作人員、還是工作人員離開位置後的座椅。 被動式的偵測方式在本發明中則有較高判斷準確度。最常見 ® 的被動式彳貞測就是被動紅外線（passive infrared，PIR)感測 器。被動紅外線感測器可以偵測一定範圍内、有溫度的物件 的移動。這在安全監控的領域裡是常用到的元件，但是由於 其無法區別貓狗的移動與人類的移動而有誤判之虞，因此近 年來應用漸趨狹隘，但對本發明所應用的生產環境而言，由 於可以區別有溫度的人體以及溫度相對低許多的座椅，反而 相當適當。如第3c圖所示，被動式的人員偵測單元240，由 19 201005301 於只需要一個被動紅外線感測器244，其實更為簡單。 還有一種被動式的偵測方式是在人員偵測單元240裡採 用一攝影鏡頭，然後人員偵測單元240裡對攝影鏡頭所擷取 的影像進行移動偵測的方式作判斷。這種方式同樣在安全監 控的領域已經相當流行。藉由適當的演算法，這種被動式偵 測可以達到最高的準確度，但是人員偵測單元240要變得比 第3b、3c圖複雜許多，而且本偵測裝置100的成本也會高很 〇 多° 第3d圖所示係依據本發明另一實施例的偵測裝置的微 處理器電路的功能方塊圖。在本實施例中，微處理器電路200 額外包含一個控制界面單元250。該控制界面單元250係提 供本發明的偵測裝置100 —個人機界面，其與偵測裝置100 外殼的一或多個按鍵（未圖示）電氣連接並與處理器單元220 的若干輸入輸出連接（亦即雙向的訊號交換），以提供設定處 0 理器單元220運作上的若干參數（例如工作人員重新出現後 多少時間以後，才恢復依據比較放大單元210輸出的結果來 驅動警示單元230)、開關偵測功能、開關警示功能等。控制 界面單元250可進一步包含一個小型液晶面板（未圖示），以 顯示目前偵測裝置100的狀態、或供檢視參數、設定之用。 處理器單元220也可以將警示訊息顯示於面板之上。 由於一般生產環境包含多條生產線，每一生產線又包含 20 201005301 眾多工作站，若需要逐一設定與監控每一工作站的本偵測敦 置100勢必耗費相當人力與時間，因此第4a圖所示本發明的 微處理器電路200又一實施例裡，微處理器電路200額外增 加一個網路界面單元260。該網路界面單元260與偵測骏置 的一個網路界面140電氣連接，並與處理器單元220之間透 過處理器單元220的輸入與輸出進行雙向的資料交換。該網 路界面140提供一個與外部網路300的連線功能。網路3〇()It is also desirable to have an energy sensor that reflects back from the worker, such as the infrared receiver 242 shown in the figures. In the normal life of our people, there are many similar applications for this active detection technology. Therefore, the components such as the transmission source and the sensor and related circuits have been widely used to expose the modules that can be followed or ready-made. For example, active infrared detection is common in automatic flushing fixtures, and those using ultrasonics can find similar applications in the car's reversing radar. As shown, an output of processor unit 220 控制 controls an electronic switch 243 to turn the illumination of infrared LED 241 on or off. The detection result of the infrared receiver 242 is transmitted to an input of the processor unit 220. For the purpose of the present invention, the active detection has certain effectiveness, but the seat of the worker is often provided in front of the workstation, and the personnel detecting unit 240 does not easily distinguish between the worker in front of the workstation and the seat after the worker leaves the position. The passive detection method has higher judgment accuracy in the present invention. The most common ® passive guess is the passive infrared (PIR) sensor. Passive infrared sensors detect the movement of objects in a range of temperatures. This is a commonly used component in the field of security monitoring, but since it cannot distinguish between the movement of the dog and the dog and the movement of the human being, there is a misjudgment, so the application has become narrower in recent years, but for the production environment to which the present invention is applied, Because it is possible to distinguish between a human body with a temperature and a seat with a relatively low temperature, it is quite appropriate. As shown in Fig. 3c, the passive personnel detecting unit 240, by 19 201005301, requires only one passive infrared sensor 244, which is actually simpler. There is also a passive detection method in which a photographic lens is used in the person detecting unit 240, and then the person detecting unit 240 determines the manner of motion detection of the image captured by the photographic lens. This approach is also quite popular in the field of security monitoring. With proper algorithms, this passive detection can achieve the highest accuracy, but the personnel detection unit 240 is much more complicated than the 3b and 3c diagrams, and the cost of the detection apparatus 100 is also high. Fig. 3d is a functional block diagram of a microprocessor circuit of a detecting device according to another embodiment of the present invention. In the present embodiment, microprocessor circuit 200 additionally includes a control interface unit 250. The control interface unit 250 provides the detecting device 100 of the present invention, a personal computer interface, which is electrically connected to one or more buttons (not shown) of the detecting device 100 housing and connected to several input and output of the processor unit 220. (i.e., bidirectional signal exchange) to provide a number of parameters in the operation of the setting unit 220 (e.g., how much time after the reappearance of the staff member resumes the warning unit 230 based on the output of the comparison amplifying unit 210) , switch detection function, switch warning function, etc. The control interface unit 250 can further include a small liquid crystal panel (not shown) for displaying the status of the current detecting device 100, or for viewing parameters and settings. The processor unit 220 can also display an alert message on the panel. Since the general production environment includes multiple production lines, each production line contains 20 201005301 many workstations. If it is necessary to set and monitor each workstation one by one, it will take considerable manpower and time, so the invention shown in Fig. 4a In still another embodiment of microprocessor circuit 200, microprocessor circuit 200 additionally adds a network interface unit 260. The network interface unit 260 is electrically connected to a network interface 140 of the detection unit and exchanges data with the processor unit 220 through the input and output of the processor unit 220. The network interface 140 provides a connection to the external network 300. Network 3〇()

Depending on the network used, the web interface 140 provides a compatible physical interface (eg, an interface of the RJ45 to connect to a wired local area network as shown in FIG. 4b, and the present device 100 of multiple workstations can pass through The network 300 is centrally monitored by a monitoring host 400. Therefore, when the processor unit 220 finds that the resistance value of the loop is abnormal, the processor unit 220 can transmit the warning signal in addition to the warning unit 230 to simultaneously transmit the network interface. The unit 260 and the network 300 actively send a message to the monitoring host 400, or the monitoring host 400 can periodically communicate with the processor unit 22 of each detecting device 100 in a polling manner to obtain the Detectives. The status of the measuring device 100 (for example, whether or not an alarm signal is generated). At the same time, the monitoring host 400 can also set its parameters, turn on and off the warning function, etc. for the specific sampling device 100 or all the detecting devices 100 through the network 300. 201005301 a green idea to the wired network connected by bus structure shown in Figure 4b. But what can be immediately inferred is that other network architectures, for example For example, a network switch or a hub can also be applied to the present invention. Further, the network interface unit 260 can include a wireless transceiver, and the network 3 is compatible with the network. 802.1 la/b/g wireless local area network, etc. In other words, the present invention does not specifically limit which protocol is used for wired, wireless, or network. © Figure 4b The connection of the road interface 140 and the sharing of the ground and power connections through the interface 150 are separately implemented. As in the other embodiment of the present invention shown in the & Figure, the network interface 140 is integrated into the interface 15 In addition to the transmission of power 、-, grounding, the cable 7 is also responsible for the aforementioned two-way bead exchange function. For example, the interface 150, the slow line can use the 45 interface and the twisted pair used by the regional network. Twisted paimbie. RJ_45 interface and twisted pair view use 8 wires, of which only 4 wires are used for (4) transmission, because you can use 2 of the remaining 4 wires for this power and ground. To pass. Related details For those who are familiar with the Internet connection, they should be easily inferred, so they are no longer embarrassed; +. Negative. Please note that from the example of the twisted pair cable above, because it is used, it is used in the soil. The different wires, the cable 700 for serial connection, and the cable 710 for the 35 $ line with the external power supply can be the same. The actual ~ earing case shown in Figure 4c is further omitted. The external power supply 60 is provided by the monitoring host 400 and is responsible for providing power and ground (i.e., the outer 22 201005301 power supply 60 and the monitoring host 400 are combined into the same device). Please note that each of the detecting devices 100 in Figures 4b to 4d is still connected to the grounding ground 50, but is not shown for the sake of simplicity. As mentioned above, the two interfaces 150 of each detecting device 100 may be identical, and there is no limitation as to which one must be used to connect the previous stage, and which one must be used to connect the detecting device 100 of the subsequent stage. However, when implementing the system as shown in FIG. 4c, it is often specified that one interface 150 is used to connect the previous level 0 (farther from the monitoring host 400), and the other interface 150 is used to connect the latter level (from the monitoring level). Host 400 is closer). The purpose of setting such a sequence is that when the monitoring host 400 finds that the state of the detecting device 100 is abnormal, it can be known that the detecting device 100 is generated by the foregoing connecting sequence (that is, the state abnormality can be known. Detecting the position of the device 100). This is very helpful for repairing and managing the system shown in Figure 4c. This should not be difficult to infer the details of a connector that is familiar with similar daisy chain methods. ® It should be emphasized again that although the above mentioned mainly the wearing of the wristband is the main detection object of the detection device, the wristband is also the most common anti-static mechanism for the operator, but the detection device The spirit can be applied to any anti-static mechanism that touches two human skins with two wires and then leaks static electricity from the two wires. It is not limited to wristbands. Moreover, in addition to the grounding mechanism of the two wires, the special electrical connection method of the present invention is more suitable for detecting a wristband using a single wire, which is another major difference and improvement from the prior application. 23 201005301 As shown in Figure 5a, a worker 80 using a single-wire wristband 30 typically needs to be mated with a grounded conductive floor 90 (typically the worker 80 also wears a shoe loop 33 to enhance electrical conductivity). The detecting device 100 of the present embodiment is substantially identical to the foregoing detecting device 100 for two wires. Thus, interface 110 is also suitable for use with a two-wire wrist strap or other grounding mechanism, but with a suitable connector (not shown), a single wire 32 of wristband 30 and an appropriate line in interface 110 are connected. The detecting device 100 shown in Fig. 5b uses an interface 160 which is only suitable for a single-conductor twisted wire, and is also not connected between the interface 160 and the interface 120 connected to the grounding ground 50. In addition to this, the single-wire and double-wire detection devices 100 can be identical. As indicated by the dashed lines in Figures 5a and 5b, the circuit detected by the microprocessor circuit 200 of the detecting device 100 is the wire 32, the wristband 30, the body of the worker 80, the conductive floor 90, and then the ground, back. It is to the microprocessor circuit 200 (or, in other words, to detect the resistance seen between the interface 120 and the wire 32). ® Therefore, unlike the grounding mechanism of the two-wire, the grounding mechanism of the detecting device 100 for the two wires constitutes a loop inside the device, and the grounding mechanism for the single wire is formed by the earth. Please note that the above-mentioned grounding backup, electrostatic leakage mode, simultaneous monitoring of other grounding mechanisms in series or parallel, network connection, and wireless detection of the presence of the staff are all applicable to the 5a and 5b diagrams. Detection device 100. Moreover, the same detecting device 100 can simultaneously detect the grounding mechanism of each one or more single wires and two wires. These 24 201005301 changes should all be derived from the above embodiments, so I will not repeat them. The above description of the specific embodiments is intended to provide a more detailed description of the features and spirit of the present invention, and is not intended to limit the scope of the present invention. On the contrary, it is intended to cover a variety of changes and equivalences within the scope of the patent application to which the present invention is intended.
