Description
本發明係有關於一儀表資訊之偵測記錄系統，特別係指一種遠端智慧偵測控制儀表之無線物聯網系統之方法及其裝置。The present invention relates to a detection and recording system for instrument information, and more particularly to a method and device for a wireless Internet of Things system for remote intelligent detection and control of instruments.
關於家家戶戶所使用的天然氣瓦斯表、電表及水表等，其在每隔一定的時間需讀表記錄其上的度數，俾結算每戶使用的度數而收取費用，其傳統方法係以人工方式由一抄表員至每戶的儀表處來讀表並記錄；隨著電子技術的發展，一種可攜式電子產品可以由一抄表員攜帶至每戶的儀表處來獲取儀表的資訊而可縮短讀表及記錄的時間，但常遇有用戶不在家或儀表周遭的地形地物的遮蔽等因素，而無法即時完成讀表抄表的工作。As for the natural gas meters, electricity meters and water meters used by every household, the readings on the meters need to be read and recorded at regular intervals so as to settle the usage of each household and collect the fees. The traditional method is for a meter reader to read and record the meters manually at each household's meter. With the development of electronic technology, a portable electronic product can be carried by a meter reader to each household's meter to obtain meter information and shorten the time for reading and recording. However, it is often the case that the user is not at home or the terrain around the meter is blocked, and the meter reading work cannot be completed immediately.
其中，隨著電子技術的發展，藉由一種微電腦天然氣瓦斯表的開發，各用戶的微電腦天然氣瓦斯表資訊以有線方式集結於一傳送器，然後再以有線電話網路方式傳送至一抄表中心，前述有線抄表方式具有建置及維護成本高且系統通信不穩定的缺點；後續發展出一區域無線讀表的方式，其即在每一儀表搭載一無線子機以無線方式傳輸儀表的資訊，一抄表員可攜帶一無線接收器至一用戶門口來喚醒無線子機而接收儀表的資訊，前述區域無線抄表方式仍具有成本高且系統通信不穩定的缺點，且喚醒每一無線子機需1~2分鐘的時間成本及耗電量大。Among them, with the development of electronic technology, through the development of a microcomputer natural gas meter, the information of each user's microcomputer natural gas meter is gathered in a transmitter in a wired manner, and then transmitted to a meter reading center in a wired telephone network manner. The aforementioned wired meter reading method has the disadvantages of high construction and maintenance costs and unstable system communication; subsequently, a regional wireless meter reading method was developed, which is to equip each meter with a wireless handset to transmit the meter information in a wireless manner. A meter reader can carry a wireless receiver to a user's door to wake up the wireless handset and receive the meter information. The aforementioned regional wireless meter reading method still has the disadvantages of high cost and unstable system communication, and it takes 1 to 2 minutes to wake up each wireless handset, and the power consumption is high.
另一種接收傳遞方式是採用NB-IOT窄頻物聯網(Narrowband Internet of Things)的公有協定方式，其係每一微電腦天然氣瓦斯表搭載一使用者身分模組(Subscriber Identity Module，SIM)之一通訊設備以全球行動通訊系統(Global System for Mobile Communications，GSM)方式來進行傳遞接收的溝通，每一通訊設備搭載一SIM卡及喚醒的運作時間約1分鐘，也是高成本及耗電量大。Another receiving and transmitting method is to adopt the public protocol of NB-IOT narrowband Internet of Things. Each microcomputer natural gas meter is equipped with a communication device with a subscriber identity module (SIM) to communicate with the global system for mobile communications (GSM). Each communication device is equipped with a SIM card and the operation time of waking up is about 1 minute, which is also high cost and consumes a lot of power.
本發明之主要目的即在提供一種遠端智慧偵測控制儀表之無線物聯網系統之方法及其裝置，其具有無線方式偵測控制儀表之功效而免除人工式讀表抄表的工作。The main purpose of the present invention is to provide a method and device for a wireless Internet of Things system for remote intelligent detection and control of instruments, which has the effect of wirelessly detecting and controlling instruments and eliminating the work of manual meter reading.
本發明之次要目的即在提供一種遠端智慧偵測控制儀表之無線物聯網系統之方法及其裝置，其能即時偵測異常資訊而進行處理。A secondary purpose of the present invention is to provide a method and device for a wireless Internet of Things system for remote intelligent detection and control of instruments, which can detect abnormal information in real time and process it.
本發明之再一目的即在提供一種遠端智慧偵測控制儀表之無線物聯網系統之方法及其裝置，其具有省電之功效。Another object of the present invention is to provide a method and device for a wireless Internet of Things system for remote intelligent detection and control of instruments, which has the effect of saving power.
本發明之另一目的即在提供一種遠端智慧偵測控制儀表之無線物聯網系統之方法及其裝置，其能提供大量數據的統計分析。Another object of the present invention is to provide a method and device for a wireless Internet of Things system for remote intelligent detection and control of instruments, which can provide statistical analysis of a large amount of data.

該網路伺服器單元16係藉由通用封包無線服務技術(GPRS, General Packet Radio Service)而具有網際網路功能而電性連接該廣播收發單元14，用以接收及傳遞該廣播收發單元14之該第二無線收發資訊模組之資訊。The network server unit 16 has an Internet function through General Packet Radio Service (GPRS) and is electrically connected to the broadcast transceiver unit 14 to receive and transmit information from the second wireless transceiver information module of the broadcast transceiver unit 14.
該應用服務單元18如一天然氣公司係具有網際網路功能而電性連接該網路伺服器單元16，其至少包含一第三中央處理單元及一資訊資料庫用以接收儲存該廣播收發單元16之該第二無線收發資訊模組之資訊及傳遞控制各該感知裝置12所對應的儀表11之使用狀態之指令，例如，當偵測到其中一儀表一直處於天然氣壓力為低壓狀態，則該應用服務單元18之資訊資料庫會發出警訊，用以該應用服務單元18主動來解決是否有漏氣的危險性，當偵測到其中一儀表已繳納使用天然氣之欠費，則該應用服務單元18之資訊資料庫會發出訊息，用以該應用服務單元18即時地傳遞指令來控制該儀表11為開啟狀態。The application service unit 18 is a natural gas company that has Internet functionality and is electrically connected to the network server unit 16. It includes at least a third central processing unit and an information database for receiving and storing information from the second wireless transceiver information module of the broadcast transceiver unit 16 and transmitting instructions for controlling the usage status of the meters 11 corresponding to each of the sensing devices 12.

When it is detected that one of the meters has paid the arrears for the use of natural gas, the information database of the application service unit 18 will issue a message so that the application service unit 18 can immediately send instructions to control the meter 11 to be turned on.
各該感知裝置12之第一無線收發資訊模組係以一低功耗廣域網路(Low Power Wide Area Network，LPWAN)之無線通訊方式來對應該廣播收發單元14而接收及傳遞資訊，該低功耗廣域網路之無線通訊係為一預定頻率及採用一私有協定。The first wireless information transceiver module of each sensing device 12 receives and transmits information in response to the broadcast transceiver unit 14 using a wireless communication method of a low power wide area network (LPWAN). The wireless communication of the low power wide area network is a predetermined frequency and adopts a private protocol.
該廣播收發單元14之該第二無線收發資訊模組係包含一使用者身分模組(Subscriber Identity Module，SIM)以全球行動通訊系統(Global System for Mobile Communications，GSM)方式而可經由一屬於該網路伺服器單元16之基地台來對應該網路伺服器單元16而接收及傳遞資訊，其包含該廣播收發單元14的時間對應該網路伺服器單元16的時間。The second wireless transceiver information module of the broadcast transceiver unit 14 includes a subscriber identity module (SIM) that can receive and transmit information to the network server unit 16 via a base station belonging to the network server unit 16 in a global system for mobile communications (GSM) manner, including the time of the broadcast transceiver unit 14 corresponding to the time of the network server unit 16.
各該感知裝置12係常態性睡眠，其通常係自我計時而喚醒及其對應的儀表有異常訊息而喚醒。Each of the sensing devices 12 is in normal sleep mode, and is usually awakened by self-timing and by abnormal signals from its corresponding instrument.
該廣播收發單元14係以一系列主要時段的時間對各該感知裝置12進行一主要廣播及通知下一次該主要廣播時間，其中，每一主要時段依序包含一第一時段及一第二時段之時序。The broadcast transceiver unit 14 performs a main broadcast to each of the sensing devices 12 at a series of main time periods and notifies the next main broadcast time, wherein each main time period sequentially includes a first time period and a second time period.
在該第一時段時，各該感知裝置12在常態性睡眠情況下而可分別地自我計時而喚醒，使得該廣播收發單元14係對各該感知裝置12進行該主要廣播及通知下一次該主要廣播時間，且各該感知裝置12來分別進行如下動作後而睡眠：During the first period, each of the sensing devices 12 can be awakened by self-timing in a normal sleep state, so that the broadcast transceiver unit 14 performs the main broadcast and notifies the next main broadcast time to each of the sensing devices 12, and each of the sensing devices 12 performs the following actions and then sleeps:
1. 可分別地溝通該廣播收發單元14，用以各該感知裝置12的時間對應該廣播收發單元14的時間，使得該廣播收發單元14以批次處理各該感知裝置12或選擇適當的感知裝置12在後續分別地自我計時而喚醒及溝通其餘的感知裝置12接收下一次該主要廣播時間。1. The broadcast transceiver unit 14 can be communicated separately so that the time of each sensing device 12 corresponds to the time of the broadcast transceiver unit 14, so that the broadcast transceiver unit 14 processes each sensing device 12 in batches or selects appropriate sensing devices 12 to self-time separately in the future to wake up and communicate with the remaining sensing devices 12 to receive the next main broadcast time.
2. 對應的儀表有異常訊息的感知裝置12通知該廣播收發單元14，用以該廣播收發單元14處理異常訊息，例如該廣播收發單元14接收一訊息而傳遞予該應用服務單元18，進而該應用服務單元18儲存及/或傳遞指令予該廣播收發單元14來控制各該感知裝置12所對應的儀表11之使用狀態。2. The sensing device 12 of the corresponding instrument notifies the broadcast transceiver unit 14 for the broadcast transceiver unit 14 to process the abnormal message. For example, the broadcast transceiver unit 14 receives a message and transmits it to the application service unit 18, and then the application service unit 18 stores and/or transmits instructions to the broadcast transceiver unit 14 to control the usage status of the instrument 11 corresponding to each sensing device 12.
該第二時段係包含一系列次要時段，每一次要時段作為係包含該批次處理的感知裝置12或選擇適當的感知裝置12的其中一感知裝置12自我計時而喚醒來溝通該廣播收發單元14後而睡眠、對應的儀表有異常訊息的感知裝置12溝通該廣播收發單元而睡眠或前述組合，用以該廣播收發單元14處理溝通的感知裝置；通常批次處理的或選擇適當的感知裝置12的作為是該應用服務單元18所欲進行的主動溝通，而對應的儀表有異常訊息的感知裝置12的溝通是回報溝通。The second time period includes a series of secondary time periods, each secondary time period includes the batch processing sensing device 12 or one of the sensing devices 12 selected to be appropriate wakes up by self-timing to communicate with the broadcast transceiver unit 14 and then goes to sleep, the sensing device 12 whose corresponding instrument has an abnormal message communicates with the broadcast transceiver unit and goes to sleep, or the aforementioned combination, for the broadcast transceiver unit 14 to process the sensing device for communication; usually the batch processing or the selection of appropriate sensing devices 12 is the active communication that the application service unit 18 wants to perform, and the communication of the sensing device 12 whose corresponding instrument has an abnormal message is a report communication.
其中，該廣播收發單元14係提供一時段的時間槽予對應的儀表有異常訊息的感知裝置12以隨機方式選擇彼此不同的時間槽來溝通該廣播收發單元14，這是因為具有相同時間槽的感知裝置12是不能溝通該廣播收發單元14；例如該廣播收發單元14係提供30秒的時間，每3秒為一時間槽，則有10個排序的時間槽可被選擇。Among them, the broadcast transceiver unit 14 provides a time slot of a period of time to the corresponding instrument. The sensing device 12 with abnormal information randomly selects different time slots to communicate with the broadcast transceiver unit 14. This is because the sensing device 12 with the same time slot cannot communicate with the broadcast transceiver unit 14; for example, the broadcast transceiver unit 14 provides 30 seconds of time, and each 3 seconds is a time slot, so there are 10 sorted time slots that can be selected.
在設計上，各該感知裝置12可以0.3秒~3秒來溝通該廣播收發單元14，用以提供對應的儀表之資訊或接收指令來控制對應的儀表11之使用狀態；每一主要時段之該第一時段的批次處理如選擇5~10個感知裝置12，用以在該第二時段之該系列次要時段來逐一喚醒而進行該應用服務單元18藉該廣播收發單元14主動性的溝通，下一個主要時段之該第一時段的批次處理則選擇另外5~10個感知裝置12；另一方面，在該第二時段之該系列次要時段也逐一進行對應的儀表有異常訊息的感知裝置12的回報溝通，用以不斷地確認各該儀表11的正常性。In terms of design, each sensing device 12 can communicate with the broadcast transceiver unit 14 every 0.3 seconds to 3 seconds to provide information of the corresponding instrument or receive instructions to control the usage status of the corresponding instrument 11; for example, 5 to 10 sensing devices 12 are selected for batch processing in the first time period of each main time period, so as to wake them up one by one in the series of secondary time periods of the second time period and conduct active communication with the application service unit 18 through the broadcast transceiver unit 14, and another 5 to 10 sensing devices 12 are selected for batch processing in the first time period of the next main time period; on the other hand, in the series of secondary time periods of the second time period, the feedback communication of the sensing devices 12 with abnormal messages of the corresponding instruments is also conducted one by one, so as to continuously confirm the normality of each instrument 11.
在設計上，各該感知裝置12係常態性睡眠，其自我計時而喚醒後的作為係該廣播收發單元14在廣播或溝通後會發出一個計時封包予各該感知裝置12或溝通的感知裝置12，然後各該感知裝置12或溝通的感知裝置12隨即睡眠而開始計時；對應的儀表有異常訊息的感知裝置12的機制作為係該廣播收發單元14發出一訊息(Flag旗標)後，則對應的儀表有異常訊息的感知裝置12自我喚醒而以隨機方式選擇彼此不同的時間槽來回報其標籤資訊予該廣播收發單元14，然後該廣播收發單元14再依標籤資訊溝通處理該感知裝置12並發出一個計時封包予溝通的感知裝置12，然後溝通的感知裝置12即睡眠而開始計時。In design, each of the sensing devices 12 is in normal sleep state. When it wakes up by self-timing, the broadcast transceiver unit 14 will send a timing packet to each of the sensing devices 12 or the communicating sensing devices 12 after broadcasting or communicating. Then, each of the sensing devices 12 or the communicating sensing devices 12 will sleep and start timing. The corresponding sensing device 12 with abnormal information on the instrument will be activated by the broadcast transceiver unit 14. After sending a message (Flag), the corresponding sensor device 12 with abnormal information on the instrument wakes itself up and randomly selects different time slots to report its tag information to the broadcast transceiver unit 14. Then the broadcast transceiver unit 14 communicates and processes the sensor device 12 according to the tag information and sends a timing packet to the communicating sensor device 12. Then the communicating sensor device 12 goes to sleep and starts timing.
本發明所揭遠端智慧偵測控制儀表之無線物聯網系統之裝置，其中，每一主要時段包含至少一該廣播收發單元14沒有使用該預定頻段之間隔時段，換言之，該廣播收發單元14會在該間隔時段切換至另一預定頻段來廣播，用以一預定的感知裝置12如一段時間沒有收到訊息的感知裝置12會自我喚醒並切換至該另一預定頻段一段時間來接收該廣播收發單元14的廣播訊息，這機制還可以用來通知各該感知裝置12轉換至其他預定頻段來進行溝通，主要係用以解決原來使用的頻段被干擾的問題，用以使該區域感知廣播收發單元10轉換至其他預定頻段來進行溝通。The invention discloses a wireless Internet of Things system for remote intelligent detection and control instruments, wherein each main time period includes at least one interval time period in which the broadcast transceiver unit 14 does not use the predetermined frequency band. In other words, the broadcast transceiver unit 14 will switch to another predetermined frequency band to broadcast during the interval time period, so as to detect a predetermined sensing device 12 that has not received a message for a period of time. The device 12 will wake itself up and switch to the other predetermined frequency band for a period of time to receive the broadcast message of the broadcast transceiver unit 14. This mechanism can also be used to notify each of the sensing devices 12 to switch to other predetermined frequency bands for communication. It is mainly used to solve the problem of interference with the originally used frequency band, so that the regional sensing broadcast transceiver unit 10 can switch to other predetermined frequency bands for communication.
本發明所揭遠端智慧偵測控制儀表之無線物聯網系統之裝置，其中，該廣播收發單元14係可採取該系列主要時段為週期性時間如8、10、12或15分鐘或該系列次要時段為週期性時間如1、2或3分鐘，或者，該系列主要時段及該系列次要時段均為週期性時間。The present invention discloses a device of a wireless Internet of Things system of a remote intelligent detection and control instrument, wherein the broadcast transceiver unit 14 can adopt the series of main time segments as periodic time such as 8, 10, 12 or 15 minutes or the series of secondary time segments as periodic time such as 1, 2 or 3 minutes, or the series of main time segments and the series of secondary time segments are both periodic time.
本發明為節約能源，在設計上，各該感知裝置12在喚醒時而被溝通後即會睡眠，換言之，其中一感知裝置12在喚醒時而沒有被溝通則不會睡眠，例如其中一感知裝置12所使用的頻段被干擾而沒有收到訊息，為此，各該感知裝置12可設計有最大喚醒時間以避免耗電問題。The present invention is designed to save energy. Each of the sensing devices 12 will sleep after being communicated when awakened.
