[0037] After introducing the technical solutions of the embodiments of the present invention, various non-limiting implementation methods of the present application are described in detail below.

[0038] In one or more embodiments, Figure 1 As shown, this embodiment provides a method for online monitoring of the accuracy of a gateway table, including the following processing procedures:

[0039] Step 1: Obtain the temperature, humidity, voltage, current and pulse data of the gateway meter in real time;

[0040] In the specific implementation, the collection of temperature, humidity, voltage, current and pulse data of the gateway meter includes the following processing procedures: based on the temperature monitor, humidity monitor, voltage transformer, current transformer and pulse quantity collector set at the preset position of each gateway meter, the signal collection of temperature, humidity, voltage, current and pulse data is realized, and the signals collected by each gateway meter are centrally transmitted to the main station server using a multi-level transmission method.

[0041] In the specific implementation, the multi-level transmission is specifically as follows: the gateway table on the terminal side is divided into several groups based on the adjacent relationship, each group of gateway tables transmits the collected signals to a common data acquisition unit, the data acquisition unit compresses the collected signals of several gateway tables through the gateway table branch controller and forwards them to the industrial computer, and the industrial computer sends the integrated signal to the main station server.

[0042] In the specific implementation, the method also needs to obtain the location data of the gateway table, and use the location data as the unique identifier of the temperature, humidity, voltage, current and pulse data collected by each gateway table. When the accuracy of the gateway table is detected to be abnormal, the location of the abnormal gateway table is determined by the unique identifier.

[0043] Specifically, Figures 2 to 5 As shown in the example, the method described in this embodiment adopts the following hardware settings in specific implementation:

[0045] The input end of the gateway table branch controller 1 is electrically connected to the output end of the data acquisition unit 2, the output end of the gateway table branch controller 1 is electrically connected to the input end of the industrial computer 3, and the output end of the industrial computer 3 is connected to the input end of the master station server 4 through a network communication signal;

[0046] The output end of the gateway table branch controller 1 is electrically connected to the input end of the industrial computer 3. The industrial computer 3 is a reinforced enhanced personal computer with dustproof, moisture-proof, corrosion-proof, radiation-proof and other characteristics, which effectively ensures the accuracy of the data. The output end of the industrial computer 3 is connected to the input end of the main station server 4 through a network communication signal. The main station server 4 includes a data storage unit 401, a data processing unit 402, a data analysis unit 403 and a data calling unit 404.

[0047] It should be noted that the main station server 4 and the cloud server 5 are connected via a two-way network communication signal. The data storage unit 401 can be backed up to the cloud through the cloud server 5, so that when the data storage unit 401 is damaged, historical data can be retrieved through the cloud server 5.

[0048] The main station server 4 is connected to the mobile unit 6 via a two-way network communication signal, the output end of the main station server 4 is electrically connected to the input end of the alarm unit 7, and the input end of the main station server 4 is connected to the output end of the image monitoring unit 8 via a network communication signal.

[0049] The input end of the data acquisition unit 2 is electrically connected to the output ends of the first gateway table 9 , the second gateway table 10 and the third gateway table 11 , respectively.

[0050] The data acquisition unit 2 includes a temperature monitor 201 , a humidity monitor 202 , a voltage transformer 203 , a current transformer 204 and a pulse quantity collector 205 .

[0051] The image monitoring unit 8 includes an automatic focusing camera 801, a video dynamic recognition unit 802, a video frame labeling unit 803, a video transmission unit 804 and a video storage unit 805. The automatic focusing camera 801 can automatically focus on the dynamic objects through the video dynamic recognition unit 802, so as to ensure that the dynamic objects can be seen clearly. The network communication is one or more of a communication network, a local area network, a wide area network and a satellite communication network.

[0052] The main station server 4 includes a data storage unit 401 , a data processing unit 402 , a data parsing unit 403 and a data calling unit 404 .

[0053] The cloud server 5 includes a cloud storage unit and a data reading unit, and the cloud storage unit is used to store data in the cloud.

[0054] The mobile unit 6 includes a mobile phone and a tablet, and the mobile phone is used to enable the staff to receive prompts in time.

[0055] The alarm unit 7 includes an alarm light and a speaker. The alarm light is used to enable the staff to find abnormalities in time.

[0056] In a specific implementation, the acquisition of the temperature, humidity, voltage, current and pulse data of the gateway meter is specifically performed by collecting the temperature, humidity, voltage, current, pulse data and position information of the first gateway meter 9, the second gateway meter 10 and the third gateway meter 11 monitored by the image monitoring unit 8 through the temperature monitor 201, humidity monitor 202, voltage transformer 203, current transformer 204 and pulse quantity collector 205 set in the gateway meter, and transmitting the information to the gateway meter branch controller 1 through an electrical signal. The first gateway meter 9, the second gateway meter 10 and the third gateway meter 11 are all connected in parallel with each other, and the first gateway meter 9, the second gateway meter 10 and the third gateway meter 11 are all connected in series with a circuit breaker. The first gateway meter 9, the second gateway meter 10 and the third gateway meter 11 are all independently connected in parallel with energy consumption modules. The energy consumption modules are turned on and off by electrical signals, and the circuit breakers are turned on and off by electrical signals. The energy consumption modules and the circuit breakers are connected to the main station server 4 by electrical signals and are controlled by the main station server 4.

[0057] In a specific implementation, the gateway table branch controller 1 compresses the data collected by multiple data acquisition units 2 and sends it to the industrial computer 3 through an electrical signal, and the industrial computer 3 sends it to the main station server 4 through network communication. The main station server 4 parses the compressed data through the data parsing unit 403 to obtain decrypted signal data for subsequent gateway table accuracy analysis.

[0058] Step 2: Based on the obtained pulse data and current, determine the relationship between the electrical frequency of the pulse data and the electrical frequency of the current. When the electrical frequency of the pulse data exceeds the preset threshold range and is different from the electrical frequency of the current, it is preliminarily determined that the accuracy of the gateway meter is abnormal.

[0059] In a specific implementation, the data processing unit 402 inside the main station server 4 determines the magnitude of the electrical frequency of the pulse data and the magnitude of the electrical frequency of the current. When the electrical frequency of the pulse data is too large or too small and is different from the magnitude of the electrical frequency of the current, it is considered data abnormality, and the alarm unit 7 is directly activated to give a prompt, and an alarm message is sent to the mobile unit 6 (i.e., the mobile terminal device);

[0060] Step 3: For data initially judged to be abnormal, compare the obtained temperature, humidity, voltage and current data with the pre-stored normal historical data. If the difference in the comparison result exceeds the preset threshold range, it is determined that the accuracy of the gateway table is abnormal, and an alarm is issued; and, by controlling the start and stop of the energy consumption module connected in series with the gateway table, the value change of the gateway table is obtained. If the value change meets the energy consumption of the energy consumption module, if not, it is determined that the accuracy of the gateway table is abnormal, and an alarm is issued.

[0061] In a specific implementation, the start and stop of the energy consumption module connected in series with the gateway meter is controlled by: an energy consumption module is set for each gateway meter, a circuit breaker is set between the energy consumption module and the optical port meter, and the start and stop control of the energy consumption module is realized by controlling the opening and closing of the circuit breaker, wherein the energy consumption module can be a resistor element or a low-power LED lamp. It can be understood that other low-power energy consumption modules can also be used in the specific implementation.

[0062] Specifically, after initially determining that the data is abnormal, the data processing unit 402 compares the temperature, humidity, voltage and current with the historical records in the data storage unit 401. When the temperature, humidity, voltage and current data differ too much from the historical records and the set interval range, a prompt is issued through the alarm unit 7 and the mobile unit 6.

[0063] When the data is judged to be normal, the data is saved in the data storage unit 401 as a reference for subsequent data comparison, and an additional copy of the data is saved in the cloud server 5;

[0064] Furthermore, in the solution described in this embodiment, video acquisition is also performed through the image monitoring unit 8. Specifically, the first checkpoint table 9, the second checkpoint table 10 and the third checkpoint table 11 are continuously monitored through the automatic focusing camera 801, and the video data is continuously transmitted to the main station server 4 through the video transmission unit 804, and the video storage unit 805 stores the ten-minute short video;

[0065] In a specific implementation, when the video dynamic recognition unit 802 detects that the length of the dynamic video clip in the video storage unit 805 is up to three minutes, the video frame labeling unit 803 will mark the video and transmit the short video to the main station server 4 through the video transmission unit 804.

[0066] In a specific implementation, the scheme described in this embodiment periodically turns on the energy consumption module to observe the changes in the digital display of the gateway meter, and whether the digital display changes cover the energy consumption of the energy consumption module, so as to further observe the accuracy of the gateway meter; specifically, by periodically selecting to close the circuit breaker connected in series to the first gateway meter, the second gateway meter, or the third gateway meter, the digital display changes of the gateway meter of the circuit breaker connected in series that is not closed are observed, so as to conduct technical analysis.

[0067] The following is a detailed description of the implementation process of the method described in this embodiment from the perspective of specific implementation, which specifically includes the following processing process:

[0068] 1) The temperature, humidity, voltage, current, pulse flow and position information of the first gateway table 9, the second gateway table 10 and the third gateway table 11 monitored by the image monitoring unit 8 are collected through the set temperature monitor 201, humidity monitor 202, voltage transformer 203, current transformer 204 and pulse quantity collector 205, and transmitted to the gateway table branch controller 1 through electrical signals;

[0069] 2) The gateway table branch controller 1 compresses the data collected by the multiple data collection units 2 and sends the data to the industrial computer 3 through an electrical signal, and the industrial computer 3 sends the data to the main station server 4 through network communication. The main station server 4 analyzes the compressed data through the data analysis unit 403. The compression format of the gateway table branch controller 1 is the same as the analysis format of the data analysis unit 403, so that the accuracy of the data can be effectively guaranteed;

[0070] 3) The data processing unit 402 inside the main station server 4 determines the magnitude of the electrical frequency of the pulse data and the magnitude of the electrical frequency of the current. When the electrical frequency of the pulse data is too large or too small and is different from the electrical frequency of the current, it is considered data abnormality. The alarm unit 7 is directly activated to give a prompt and an alarm message is sent to the mobile unit 6.

[0071] 4) After initially determining that the data is abnormal, the data processing unit 402 compares the temperature, humidity, voltage and current with the historical records in the data storage unit 401. When the temperature, humidity, voltage and current data differ greatly from the historical records and the set range, a prompt is issued through the alarm unit 7 and the mobile unit 6;

[0072] 5) When the data is judged to be normal, the data is saved in the data storage unit 401 as a reference for subsequent data comparison. By continuously saving the data in the data storage unit 401, the entire system can be more perfect, thereby making the detection more accurate, and an additional copy of the data is saved in the cloud server 5;

[0073] 6) The auto-focus camera 801 continuously monitors the first checkpoint table 9, the second checkpoint table 10 and the third checkpoint table 11, and continuously transmits the video data to the main station server 4 through the video transmission unit 804, and the video storage unit 805 stores the ten-minute short video. The specific storage method is to continuously delete the first ten minutes of video, so that the video storage unit 805 does not need a large capacity;

[0074] 7) When the video dynamic recognition unit 802 detects that the length of the dynamic video clip in the video storage unit 805 is as long as three minutes, the video frame labeling unit 803 will mark the video. The specific working principle of the video dynamic recognition unit 802 is to judge the pictures of multiple video frames. When the pictures of the video frames differ too much, it means that there are dynamic objects in the video, and the short video is transmitted to the main station server 4 through the video transmission unit 804.

[0075] 8) Turn on the energy consumption module regularly to observe the changes in the digital display of the gateway meter to see whether the digital display changes cover the energy consumption of the energy consumption module, so as to further observe the accuracy of the gateway meter.

[0076] 9) Regularly select and close the circuit breakers connected in series to the first, second or third gate meters, so as to observe the changes in the digital display of the gate meters of the circuit breakers connected in series, and conduct technical analysis.

[0077] The electrical components in the scheme described in this embodiment are all electrically connected to the controller and the power supply, and the control method is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field, and the provision of power supply is also common knowledge in this field.

[0078] The working principle of the above embodiment is:

[0079] A. The image monitoring unit 8 can continuously monitor the first checkpoint table 9, the second checkpoint table 10 and the third checkpoint table 11 through the automatic focusing camera 801, and can transmit the video data to the main station server 4 through the video transmission unit 804, so as to facilitate the staff to view, and the video storage unit 805 can save the video taken by the automatic focusing camera 801 within ten minutes. When the video dynamic recognition unit 802 detects that the length of the dynamic object in the video reaches three minutes, the video frame labeling unit 803 can mark the video and transmit the video to the main station server 4, so as to facilitate the subsequent staff to view.

[0080] B. The data acquisition unit 2 can collect the temperature, humidity, voltage, current and pulse flow of the first checkpoint table 9, the second checkpoint table 10 and the third checkpoint table 11, and send the data to the main station server 4. The data processing unit 402 can judge the electrical frequency size of the pulse data and the electrical frequency size of the current, so as to judge whether the data is abnormal, and the data processing unit 402 can compare the data with the data in the historical records, so as to effectively reduce the influence of temperature and humidity, and make the detection more accurate, so as to effectively judge the error of the checkpoint table.

[0084] An accuracy abnormality judgment unit is used to compare the data initially judged to be abnormal with the pre-stored normal historical data based on the obtained temperature, humidity, voltage and current data. If the difference in the comparison result exceeds the preset threshold range, it is judged that the accuracy of the gateway table is abnormal and an alarm is issued; and, by controlling the start and stop of the energy consumption module connected in series with the gateway table, the value change of the gateway table is obtained, and whether the value change meets the energy consumption of the energy consumption module, if not, it is judged that the accuracy of the gateway table is abnormal, and an alarm is issued.
