Unified supervision and preservation.

In one embodiment of the present application, refer to FIG. 3 , which is a circuit diagram of a main control module provided by an embodiment of the present application. Referring to Figure 3, the main control module includes a main control chip U2A and a main antenna terminal RF1. The first pin 46 of the main control chip U2A is connected to the first pin 2 of the main antenna terminal RF1, and the second pin 1 and the third pin 3 of the main antenna terminal are both connected to the ground GND.

In one embodiment of the present application, refer to FIG. 4 , which is a circuit diagram of an anti-tamper detection module provided by an embodiment of the present application. Referring to Figure 4, the tamper detection module includes: a first transistor Q1, a second transistor Q2, a first photoresistor R2, a first resistor R3, a second resistor R15 and a third resistor R18. The first end of the first photoresistor R2 is used to connect the voltage VBAT output by the power module. The second end of the first photoresistor R2 is connected to the first end of the first resistor R3, the first end of the second resistor R15 and the third resistor. Connect the first end of R18. The second terminal of the first resistor R3 is connected to the ground GND. The second terminal of the second resistor R15 is connected to the base of the first transistor Q1.

The second end of the third resistor R18 is connected to the base of the second transistor Q2. The collector of the second transistor Q2 is connected to the third pin 74 of the main control chip U2A, and the emitter of the second transistor Q2 is connected to the ground GND.

For example, when installing an intelligent detection device on a cargo transport box, the cover plate needs to be used to seal the contact surface between the intelligent detection device and the outside to protect the intelligent detection device from water and other hazards. Thus, the anti-tamper detection module is in a sealed state.

The working principle of the anti-tamper detection module in the embodiment of this application is as follows:

In the dark state under sealed conditions, the resistance value of the first photoresistor R2 becomes larger, so the voltage of the base of the second transistor Q2 is low level, and the second transistor Q2 does not conduct. When the outer cover of the intelligent detection equipment is removed, that is, when someone wants to remove the intelligent detection equipment on the cargo transport box, light will shine on the first photoresistor R2. At this time, the resistance of the first photoresistor R2 becomes smaller, which causes the voltage of the base of the second transistor Q2 to increase, and the collector and emitter of the second transistor Q2 are connected, so that the second transistor Q2 The level of the collector of tube Q2 is pulled low. Since the collector of the second transistor Q2 is connected to the third pin 74 of the main control chip U2A of the main control module, the main control module can detect the low-level signal output by the anti-tamper detection module. Therefore, corresponding alarm information can be generated when the low-level signal is detected, and at the same time, the first position information of the intelligent detection device is collected, and then the alarm information and the first position information are sent to the data center platform. The alarm information may include corresponding alarm time information. Therefore, the anti-tamper detection module can detect when the intelligent detection equipment is dismantled and alarm in time, thereby realizing the alarm traceability function when the intelligent detection equipment is dismantled.

In one embodiment of the present application, refer to FIG. 5 , which is a circuit diagram of a state detection module provided by an embodiment of the present application. Referring to FIG. 5 , the status detection module includes a first sensor U4, a third transistor Q4, a fourth resistor R10, a fifth resistor R11, a sixth resistor R12 and a seventh resistor R9. The first end of the fourth resistor R10 is connected to the third pin 14 of the main control chip U2A, and the second end of the fourth resistor R10 is connected to the base of the third transistor Q4. The emitter of the third transistor Q4 is connected to the ground GND, and the collector of the third transistor Q4 is connected to the second pin 2 of the first sensor U4. The first pin 1 of the first sensor U4 is connected to the first end of the fifth resistor R11, and the second end of the fifth resistor R11 is used to connect the power output terminal VBAT of the power module. The third pin 3 of the first sensor U4 is connected to ground GND. The fourth pin 4 of the first sensor U4 is connected to the first end of the sixth resistor R12. The second end of the sixth resistor R12 is connected to the fourth pin 15 of the main control chip U2A. The second end of the sixth resistor R12 is also connected to the first end of the seventh resistor R9, and the second end of the seventh resistor R9 is connected to the fifth pin 19 of the main control chip U2A.

In the embodiment of this application, the intelligent detection device is installed on the cargo transport box. For example, when the circulating foldable box is used, the four foldable sides need to be raised. And if the circulating foldable box is not in use, the four foldable surfaces around the circulating foldable box are folded away. If the cargo transport box is a recyclable foldable box such as a pallet box, the intelligent detection device can be installed at the bottom of the recyclable foldable box near any foldable surface, and can be detected through the status detection module based on the obstruction detection principle. Whether the corresponding foldable surface is opened or not is used to determine whether the circulating foldable box is used.

For example, when the cargo transport box is a non-foldable closed or open box for loading goods, the intelligent detection device can be installed inside the box, and the status detection module can also be used based on the principle of obstruction detection. Detect whether there are obstructions within the preset range to determine whether there are goods inside the box, so as to understand the use of the box.

The working principle of the status detection module in the embodiment of this application is as follows:

Pin 1 and pin 2 of the first sensor U4 form a signal transmitting device. Pin 3 and pin 4 of the first sensor U4 form a signal receiving device. When the circuit starts working, the main control chip U2A of the main control module outputs a high level through pin 14 and pin 15 respectively. Among them, the high level output by the main control chip U2A through pin 14 passes through the fourth resistor R10 and is input from the base of the third transistor Q4, causing the base and emitter of the third transistor Q4 to conduct. Since pin 1 of the first sensor U4 is connected to the fifth resistor R11, the fifth resistor R11 is connected to the power output terminal VBAT of the power module. This causes the electrical signals of pin 1 and pin 2 of the first sensor U4 to form a complete electrical circuit, so that the transmitting device of the first sensor U4 starts to emit signals. The high level output by the main control chip U2A of the main control module through pin 15 is input from pin 4 of the first sensor U4 after passing through the sixth resistor R12. Since the pin 3 of the first sensor U4 is directly connected to the ground GND, the receiving device of the first sensor U4 also forms a complete electrical circuit, so that the receiving device of the first sensor U4 starts to receive signals. Then, the receiving device end of the first sensor U1 is connected to the pin 19 of the main control chip U2A through the seventh resistor R9 to perform ADC signal sampling. According to the principle that when the first sensor places obstructions in different ranges above the probe, the signal value at the sensor receiving end will be different. The main control module calculates the collected voltage signal to determine the usage status of the pallet.

It should be noted that the first sensor U4 can be an active sensor (such as a light detection and ranging (lidar) sensor, a radio detection and ranging (radar) sensor, etc.), which can emit a signal toward the surrounding environment and detect the emitted signal. Sensors that reflect to scan the surrounding environment.

For example, a ranging (lidar) sensor can determine the distance to environmental features as it scans a scene to assemble a "point cloud" indicative of reflective surfaces in the environment. This can be done, for example, by determining individual points in a point cloud: sending a laser pulse and detecting the return pulse reflected from an object in the environment (if present), and then determining the distance to the object based on the time delay between the sending of the pulse and the reception of the reflected pulse. distance. Thus, for example, a three-dimensional map of points indicating the location of reflective features in the environment can be generated.

It can be understood that when the intelligent detection device is applied to a non-foldable closed or open cargo transport box for loading goods, the intelligent detection device needs to be installed inside the cargo transport box. At this time, the detection range needs to be determined based on the size of the cargo transport box, the specifications of the cargo carried, etc. (the distance between the cargo and each surface or point inside the cargo transport box after loading the cargo), so that the first step can be further determined based on the detection range. Sensor type.

In the embodiment of the present application, the usage status of the cargo transport box can be determined based on the voltage value at the receiving device end of the status detection module collected by the main control module. For circular foldable boxes, if an obstruction is detected, it means that the foldable surface is raised and the box is in use. If there is no obstruction, it means that the foldable surface is folded and the box is not in use. For non-foldable closed or open boxes used to load goods, if an obstruction is detected, it means that there is goods inside the box and the box is in use. If there is no obstruction, it means that there is no cargo inside the box and the box is unused.

In one embodiment of the present application, refer to FIG. 6 , which is a flow chart of steps in which the main control module performs ADC sampling of voltage signals to obtain status information of the cargo transport box provided by the embodiment of the present application. Including but not limited to step S601 to step S603.

Step S601: Compare the first voltage with a preset voltage threshold, where the first voltage is the voltage sampled by the ADC.

Step S602: When the first voltage exceeds the preset voltage threshold, it is determined that the cargo transport box is in an unused state.

Step S603: When the first voltage does not exceed the preset voltage threshold, it is determined that the cargo transport box is in use.

In the embodiment of the present application, the main control module collects the voltage output from the receiving device of the status detection module, and can further compare the collected first voltage with the preset voltage threshold to determine whether there is an obstruction, so as to determine whether there is an obstruction. The obstruction determines the usage status of the cargo transport box. Specifically, when the first voltage exceeds the preset voltage threshold, it means that there is no obstruction, and it can be determined that the cargo transport box is in an unused state. When the first voltage does not exceed the preset voltage threshold, it indicates that there is an obstruction, and it can be determined that the cargo transport box is in use.

For example, when the voltage output by pin 4 of the first sensor U4 collected by the main control module is greater than 1350mV, it means that the cargo transport box is in an unused state and there is no cargo inside the box. When the voltage output by pin 4 of the first sensor U4 collected by the main control module is less than 1350mV, it indicates that the cargo transport box is in use and there is cargo inside the box.

In one embodiment of the present application, refer to FIG. 7 , which is a flow chart of the main control module controlling the intelligent detection device to enter the sleep state according to the embodiment of the present application, including but not limited to step S701 to step S702.

Step S701, when it is detected that the cargo transport box is in an unused state, the unused state is sent to the data center platform and the intelligent detection device is controlled to enter a sleep state.

Step S702, or when receiving the sleep command sent by the data center platform, control the intelligent detection device to enter the sleep state according to the sleep command. The sleep command is triggered when the data center platform receives the status information of the cargo transport box as unused.

In the embodiment of the present application, the preset conditions for controlling the intelligent detection device to enter the sleep state can be set in the main control module in advance. Therefore, when the main control module detects that the current environment meets the preset conditions, it can control the intelligent detection device to enter the sleep state. For example, the preset condition can be set to enter a dormant state when the cargo transport box is not in use. Therefore, when the main control module detects that the cargo transport box is in an unused state, and after sending the unused status information to the data center platform, the main control module controls the intelligent detection device to enter a dormant state.

In the embodiment of the present application, as another feasible implementation method, no precondition setting is performed in the main control module. Instead, when the data center platform receives the status information of the cargo transport box as unused, it sends a message to the main control module. Sleep command, so that the main control module controls the intelligent detection device to enter the sleep state according to the sleep command.

In the embodiment of the present application, when the cargo transport box is in an unused state, it indicates that the cargo transport box is not loaded with goods. At this time, the intelligent detection equipment does not need to work. Therefore, by controlling the intelligent detection equipment to enter the sleep state, power consumption can be saved and the service life of the intelligent detection equipment can be improved.

In the embodiment of the present application, Figure 10 adds a temperature detection module 1004 and a first detection module 1005 to the intelligent detection device shown in Figure 1 . Therefore, compared with the intelligent detection device shown in Figure 1, the intelligent detection device shown in Figure 10 has an additional temperature detection function and a detection function of whether the status detection module is working normally. That is, on the basis of Figure 1, the intelligent detection equipment shown in Figure 10 can also detect the temperature of the cargo transportation box, thereby strengthening the safety management and protection of the cargo during transportation. At the same time, it can be detected whether the status detection module is working normally, which can further ensure the correctness of the detection results of the status detection module. This can ensure the accuracy of the detected usage status of the cargo transport box.

Specifically, the first end of the first detection module 1005 is connected to the power module 1001 for receiving the power voltage transmitted by the power module 1001. The second end of the first detection module 1005 is connected to the third end of the status detection module 1003, and is used to receive the first status signal or the second status signal transmitted by the status detection module 1003; the third end of the first detection module 1005 is connected to the main control The fourth terminal of the module 1006 is used to send the second signal or the third signal to the main control module 1006.

In the embodiment of this application, the first detection module 1005 is connected to the power module 1001, the status detection module 1003 and the main control module 1006. The first detection module 1005 is configured to send a second signal to the main control module 1006 when the status detection module 1003 is working normally, and to send a third signal to the main control module 1006 when the status detection module 1003 is abnormal.

In the embodiment of the present application, the first detection module 1005 is connected to the status detection module 1003 and the main control module 1006, so that when the status detection module 1003 is working normally, it can send a second signal to the main control module 1006 to inform the main control module 1006 The status detection module 1003 works normally, and the detection results of the status detection module 1003 are credible. At the same time, when the status detection module 1003 is abnormal, a third signal can be sent to the main control module 1006 to inform the main control module 1006 that the status detection module 1003 is working abnormally and the detection results of the status detection module 1003 are not trustworthy.

In one embodiment of the present application, refer to FIG. 11 , which is a circuit diagram of the first detection module provided by the embodiment of the present application. As shown in Figure 11, the first detection module includes a fourth transistor Q7, an eighth resistor R30, a ninth resistor R31 and a tenth resistor R32. The emitter of the fourth transistor Q7 is connected to the power output terminal VBAT of the power module, and the base of the fourth transistor Q7 is connected to the first end of the eighth resistor R30. The second end of the eighth resistor R30 is connected to the pin 1 of the first sensor U4 of the status detection module. The collector of the fourth transistor Q7 is connected to the first terminal of the ninth resistor R31, and the second terminal of the ninth resistor R31 is connected to the first terminal of the tenth resistor R32. The second terminal of the tenth resistor R32 is connected to the ground GND. The pin 12 of the main control chip U2A of the main control module is also connected between the second end of the ninth resistor R31 and the first end of the tenth resistor R32.

The working principle of the first detection module in the embodiment of this application is as follows:

When the first sensor U4 in the status detection module is connected normally and works normally, since the emitter of the fourth transistor Q7 is connected to the power output terminal VBAT of the power module, when the first sensor U4 works normally, the first sensor The transmitter circuit of U4 is working normally, so the base of the fourth triode Q7 is pulled down to a low level. According to the principle of the fourth triode as a switching circuit, when the base is at a low level, because the emitter is at a high level VBAT, the base of the fourth transistor Q7 will generate current. Because the fourth transistor Q7 has the function of current amplification, there will be a collector current. The collector current passes through the ninth resistor R31 and the tenth resistor R32 to When the ground forms a loop, a voltage drop will occur at the connection between the ninth resistor R31 and the collector, and then the voltage will be divided through the ninth resistor R31 and the tenth resistor R32, and the signal will be sent to the pin of the main control module U2A for high and low levels. Detection, if the detection result is high level, it means that the first sensor U4 is connected normally and works normally. If the detection result is low level, it means that the first sensor U4 is connected abnormally and cannot work.

The embodiment of the present application can detect whether the status detection module is working normally through the first detection circuit shown in FIG. 11 . Therefore, based on the test results, the accuracy of the use status of the cargo transport box can be ensured.

In one embodiment of the present application, the temperature detection module is connected to the power module and the main control module. The temperature detection module is used to output corresponding voltage data to the main control module according to the temperature of the cargo transport box, so that the main control module can calculate the temperature information of the cargo transport box based on the voltage data, and send the temperature information to the data platform center .

Since the main control module is connected to the temperature detection module, when receiving the voltage data output by the temperature detection module, the temperature information of the cargo transport box can be calculated based on the voltage data. The calculated temperature information is then sent to the data center platform. This can realize the temperature monitoring of cargo transportation boxes and strengthen the safety management and protection of goods during transportation.

In one embodiment of the present application, refer to FIG. 12 , which is a circuit diagram of a temperature detection module provided by an embodiment of the present application. Referring to Figure 12, the temperature detection module includes a first thermistor R40 and an eleventh resistor R41. The first end of the first thermistor R40 is connected to the power output terminal VBAT of the power module, the second end of the first thermistor R40 is connected to the first end of the eleventh resistor R41, and the second end of the eleventh resistor R41 terminal is connected to ground GND. The second pin 21 of the main control chip U2A is also connected between the second end of the first thermistor R40 and the first end of the eleventh resistor R41.

In the embodiment of the present application, the main control module U2A can sample the voltage data in the temperature detection module after passing through the first thermistor R40 through the second pin 21, and then perform calculations based on the voltage data to obtain the temperature value. The calculated temperature value is sent to the data center platform.

In one embodiment of the present application, refer to Figure 13, which is a flow chart of steps for the main control module to obtain the temperature information of the cargo transport box according to the voltage data provided by the embodiment of the present application, including but not limited to step S1301 to step S1302.

Step S1301: Calculate the corresponding resistance based on the voltage data.

Step S1302: Obtain the temperature information of the cargo transport box based on the resistance and the corresponding relationship between resistance and temperature.

In the embodiment of this application, the corresponding resistance value can first be calculated by collecting the voltage, and then based on the corresponding relationship between the resistance and the temperature, the temperature of the cargo transport box can be determined.

For example, referring to FIG. 12 , if the first thermistor R40 in FIG. 12 adopts a negative temperature coefficient NTC thermistor. Then the resistance of the first thermistor R40 will decrease as the temperature increases. Because the first thermistor R40 and the eleventh resistor R41 form a series voltage dividing circuit. The total voltage is the output voltage VBAT of the power circuit. The voltage after passing through the first thermistor R40, that is, the voltage sampled by the main control module ADC is Vadc. Then there is the formula Vadc=VBAT/(R41+R40)*R41. Since the eleventh resistor R41 is a fixed-value resistor, R40, that is, the resistance value of the first thermistor R40, can be calculated based on the voltage Vadc sampled by the main control module ADC and the formula. According to the change curve of the resistance value of the first thermistor with temperature or the corresponding relationship between the resistance value of the first thermistor and temperature, the corresponding temperature at the resistance value can be obtained. This temperature is the temperature of the cargo transport box.

In the embodiments of the present application, the correspondence table between the measured actual ambient temperature and the resistance can also be calibrated in advance through experiments. Therefore, the validity and accuracy of the calculated temperature value can be determined by detecting whether the temperature value calculated according to theory is within the range of the corresponding table.

In one embodiment of the present application, refer to FIG. 14 , which is a flow chart of steps executed by the main control module provided in the embodiment of the present application after acquiring the temperature of the cargo transport box. Including but not limited to step S1401 to step S1403.

Step S1401: When the temperature of the cargo transport box obtained according to the temperature information is lower than the first preset temperature threshold, the intelligent detection device is controlled to enter a sleep state.

Step S1402: When the duration of the intelligent detection device in the dormant state exceeds the preset duration, wake up the intelligent detection device and enter the working state.

Step S1403, or when receiving a wake-up command sent by the data center platform, wake up the intelligent detection device to enter the working state.

In the embodiment of this application, after the main control module calculates the temperature of the cargo transport box, if the temperature is lower than the first preset temperature threshold, it will control the intelligent detection device after sending the temperature of the cargo transport box to the data center platform. Enter hibernation state. At this time, since the intelligent detection equipment is not working, no power is consumed. It can reduce power consumption in low temperature environments and extend the service life of intelligent detection equipment.

For example, when it is detected that the temperature of the cargo transport box is lower than -40 degrees, the intelligent detection device is controlled to enter a sleep state.

In the embodiment of this application, after the smart detection device enters the sleep state, the main control module will start to accumulate the time the smart detection device is in the sleep state. When the duration exceeds the preset time, the smart detection device will be awakened to enter the working state. At this time, the main control module will re-collect the voltage data output by the temperature detection module, and calculate the temperature of the cargo transport box again based on the re-collected voltage data. If the temperature is still lower than the preset temperature threshold. Then control the intelligent detection device to enter the sleep state again. And if the temperature is not lower than the preset temperature threshold, the intelligent detection device is controlled to keep working.

In the embodiment of this application, as another feasible implementation manner, after the main control module controls the intelligent detection device to enter the sleep state, if it receives a wake-up command sent by the data center platform, it directly wakes up the intelligent detection device and enters the working state. That is to say, after the smart detection device enters the sleep state, even if the smart detection device is in the sleep state for less than the preset time, it will wake up directly as long as it receives the wake-up command. This ensures timely response when intelligent detection equipment is required to perform detection work and upload data. At the same time, remote control of intelligent detection equipment can also be realized.

In one embodiment of the present application, after the main control module calculates the temperature of the cargo transport box according to the steps shown in Figure 5, it can compare the temperature of the cargo transport box with the second preset temperature threshold. When the goods are transported When the temperature of the box exceeds the second preset temperature threshold, alarm information is generated, and the temperature and alarm information are sent to the data center platform.

It can be understood that the second preset temperature threshold can be determined according to the cargo carried in the cargo transport box. For example, if you are carrying some fruits and vegetables, in order to maintain the freshness of the fruits and vegetables, you need to set the corresponding temperature threshold. Therefore, when the temperature of the cargo transport box is detected to exceed the temperature threshold, an alarm can be issued so that the data center platform can remind relevant personnel to handle it.

It is understandable that due to different cargoes being carried, the corresponding temperature thresholds are different. Therefore, the temperature threshold after the temperature threshold is set can be sent to the main control module through the data center platform.

It can be understood that when the cargo being carried does not require temperature monitoring, the voltage data output by the temperature detection module can be collected from time to time through the main control module. Or the main control module collects the voltage data output by the temperature detection module at certain intervals.

It can be understood that when the cargo transport box carries goods that require low temperature detection, the low temperature threshold can be preset. Then it is sent to the main control module through the data center platform, so that the main control module generates alarm information when it detects that the temperature of the cargo transport box is lower than the low temperature threshold. The temperature of the cargo transport box and the corresponding alarm information can then be uploaded to the data center platform.

In one embodiment of the present application, refer to FIG. 15 , which is a flow chart of steps that can be performed by the main control module provided by the embodiment of the present application. Including but not limited to step S1501 to step S1502.

Step S1501: When receiving the first request sent by the data center platform, control the intelligent detection device to enter the sleep state according to the first request.

Step S1502: When receiving the second request sent by the data center platform, control the intelligent detection device to enter the working state according to the second request.

The embodiments of this application take into account that the corresponding working status of the intelligent detection device may also be different depending on the cargo loaded in the cargo transport box. Therefore, the method of presetting relevant control programs in the main control module is not very applicable. That is, once the control program is set, the intelligent detection equipment can only be used to detect cargo transport boxes loaded with a certain type of cargo, which has limitations. . Therefore, in the embodiment of the present application, the data center platform issues instructions to the main control module to control the working status of the intelligent detection equipment, so that the intelligent detection equipment can be used to detect boxes containing any goods. Specifically, when the data center platform determines that the intelligent detection device does not need to work based on the data uploaded by the main control module, it can send a first request to the main control module, so that the main control module controls the intelligent detection module to enter the sleep state according to the first request. When the data center platform determines that the intelligent detection device needs to work based on the data uploaded by the main control module, it can send a second request to the main control module, so that the main control module controls the intelligent detection module to enter the working state according to the second request.

For example, when the data center platform receives that the status information of the cargo transport box uploaded by the main control module is unused, it can send a first request to the main control module. Or, when the data center platform determines that it only needs to detect the cargo transport boxes at intervals based on the data and cargo information uploaded by the main control module, it can send a second request to the main control module when it needs to obtain detection data. The main control module controls the intelligent detection equipment to enter the working state to detect relevant data such as temperature, etc., and then uploads the detected data to the data center platform. Then, after obtaining the relevant data, the data center platform can send a first request to the main control module, so that the main control module controls the intelligent detection device to enter a sleep state according to the first request.

The embodiment of this application realizes remote control of intelligent detection equipment through the data center platform, which can effectively save the power consumption of intelligent detection equipment and improve the service life of intelligent detection equipment.

In one embodiment of the present application, the main control module is also used to enter the sleep state or the working state according to preset rules. The preset rules include:

Set the timetable for the main control module to enter the sleep state or the working state, so that the main control module switches states according to the timetable.

Or set the sleep duration or working duration of the main control module, so that the main control module switches states according to whether the duration of the sleep state reaches the sleep duration or according to whether the duration of the working state reaches the working duration.

Or set the interval time for entering the sleep state or the working state, so that the main control module enters the sleep state or the working state at intervals.

The preset rules in the embodiment of this application can be determined based on the specific type of cargo loaded in the cargo carrying box, etc. Through the setting of preset rules, the corresponding intelligent detection equipment can be controlled in a targeted manner according to the nature of the goods. It can save power consumption as much as possible and extend the service life of intelligent detection equipment while fully and effectively utilizing resources.
