Description

Technical Field

[0001] The present invention relates to the field of remote control of distribution cabinets, and specifically to a remote control system and method for distribution cabinets based on intelligent Internet of Things technology. Background Art

[0002] A distribution cabinet is an electrical device that facilitates piecemeal power configuration. It is a power distribution device used in the power supply equipment system for power distribution, control, metering, and connection of cables. The distribution cabinet plays roles such as on-off, control, or protection in the power generation, transmission, distribution, power conversion, and consumption of the power system. Therefore, the distribution cabinet occupies a very important position in the entire power industry. There are a large number of electrical components in the distribution cabinet, and faults often occur. After a fault occurs, the corresponding power supply situation will be affected. It is obvious that repairing the distribution cabinet after problems occur will affect normal power distribution. Therefore, it is very important to timely know the working conditions of the electrical components inside the distribution cabinet.

[0003] All the existing equipment placed in the distribution cabinet is live. When staff need to operate on the distribution cabinet, the steps are cumbersome and there are safety hazards. Therefore, a remote control system is needed to remotely control the distribution cabinet to improve the control efficiency and control safety of the distribution cabinet. At the same time, during the use of the distribution cabinet, it is necessary to frequently monitor the distribution cabinet, and the monitoring is often carried out by staff going to the site in person. This not only wastes time, but also the monitoring effect is not good. It is impossible to monitor the distribution cabinet in real time and ensure the continuous and stable operation of the distribution cabinet.

[0004] In view of the above technical problems, the present application proposes a solution. Summary of the Invention

[0005] In the present invention, the operating environment information is collected, and after generating an action signal, the execution effect is synchronously verified, realizing dual collection of the environment information and its own action information in the distribution cabinet, realizing monitoring of abnormal environmental interference and its own action abnormality in the distribution cabinet. At the same time, data comparison is carried out using the distribution cabinet information obtained each time to realize dynamic verification of the communication network of the distribution cabinet. When detecting deterioration of the channel quality, the communication path is automatically switched, solving the problem that there is no real-time monitoring and verification mechanism for the control execution, operating environment, and communication network of the distribution cabinet in the remote control system of the distribution cabinet, and it is easy to cause losses due to malfunction of the distribution cabinet control, and a remote control system and method for distribution cabinets based on intelligent Internet of Things technology are proposed.

[0006] The object of the present invention can be achieved by the following technical solutions:

[0007] The remote control system for distribution cabinets based on intelligent Internet of Things technology includes a remote monitoring module, a control center, and a communication supervision module. The remote monitoring module is used to monitor the operation of the distribution cabinet and execute feedback, obtain the operating environment information and action execution feedback, and send the operating environment information and action execution feedback to the control center;

[0008] The communication supervision module is used to verify the communication situation of the distribution cabinet, evaluate the communication situation according to the verification result, complete the communication switching of the distribution cabinet according to the evaluation result, and send the communication switching result to the control center;

[0009] The control center obtains the operating environment information and action execution feedback through the remote monitoring module, evaluates and judges the operating environment information, obtains the operation evaluation of the distribution cabinet, and sends the distribution cabinet evaluation through the network;

[0010] The control center can generate and send a distribution cabinet action signal to the execution feedback unit, and the execution feedback unit executes the distribution cabinet action signal;

[0011] The communication supervision module sends the communication situation to the control center. The control center makes an operation judgment on the communication situation, obtains a communication maintenance result, and displays the communication maintenance result.

[0012] As a preferred embodiment of the present invention, the remote monitoring module includes an operating environment monitoring unit and an execution feedback unit. The operating environment monitoring unit is used to monitor the operation of the distribution cabinet;

[0013] When the operating environment monitoring unit monitors the operation of the distribution cabinet, the collected operation information includes the humidity rise and fall rate, the temperature distribution difference, and the internal temperature limit value;

[0014] When the operating environment monitoring unit obtains the humidity rise and fall rate, it collects the humidity data in the distribution cabinet through a sensor, synchronously records the humidity data and the time when the humidity data is collected, and calculates according to the difference between the time interval and the humidity data to obtain the humidity rise and fall rate;

[0015] The operating environment monitoring unit collects temperature data at different positions in the distribution cabinet through a sensor, synchronously records the collection position, the collected temperature data, and the collection time, and selects the highest temperature data and the lowest temperature data from the temperature data of all positions recorded at the same moment and records them as the internal temperature limit value;

[0016] The operating environment monitoring unit calculates the average value of the temperature data of all positions at the same moment to obtain the average temperature, and calculates the difference between the temperature data of each position and the average temperature, and records the difference as the temperature distribution difference.

[0017] As a preferred embodiment of the present invention, the operating environment monitoring unit compares the humidity rise and fall rate with a set threshold. If the humidity rise and fall speed is greater than the set threshold, a normal ventilation signal is generated. If the humidity rise and fall rate is less than the set threshold, an abnormal ventilation signal is generated;

[0018] The operating environment monitoring unit compares the internal temperature limit value with the set temperature limit threshold range. If the internal temperature limit values are all within the temperature limit threshold range, a normal temperature signal is generated. If any one of the internal temperature limit values is outside the temperature threshold range, an abnormal temperature signal is generated;

[0019] The operating environment monitoring unit calculates the standard deviation of the temperature distribution difference to obtain a distribution characteristic value. If the distribution characteristic value is greater than the set threshold, a circulation abnormal signal is generated. If the distribution characteristic value is not greater than the set threshold, a circulation normal signal is generated.

[0020] As a preferred embodiment of the present invention, after receiving the power distribution cabinet action signal, the execution feedback unit executes the power distribution cabinet action signal, obtains the execution result after the execution is completed, compares the obtained execution result with the power distribution cabinet action signal. If the comparison passes, an action completion signal is fed back. If the comparison fails, an action failure signal is fed back, and the action completion signal or the action failure signal is sent to the control center.

[0021] As a preferred embodiment of the present invention, the communication supervision module includes a communication verification unit and a communication switching unit. The communication verification unit conducts verification supervision through the information transmission between the power distribution cabinet and the control center. The method of verification supervision is as follows:

[0022] The communication verification unit obtains the operating environment information through the operating environment monitoring unit every certain period of time and records the operating environment information. The communication verification unit compares the operating environment information obtained multiple times to obtain the change situation of the operating environment information. If the number of consecutive times that the operating environment information has not changed exceeds the set number of times, it is determined that the communication is abnormal. If the operating environment information is not obtained, it is determined that the communication is interrupted. Otherwise, it is determined that the communication is normal, and the communication interruption or communication abnormality is fed back to the communication supervision module.

[0023] As a preferred embodiment of the present invention, after detecting communication interruption or communication abnormality, the communication switching unit obtains the currently running network mode through the communication supervision module, switches the network mode, and generates a switching signal to be sent to the control center. After receiving the switching signal, the control center switches the sensor network in the power distribution cabinet to change the information transmission network.

[0024] As a preferred embodiment of the present invention, after generating the switching signal, the communication switching unit simultaneously feeds back the switching signal to the communication supervision module. After receiving the switching signal, the communication supervision module monitors the communication situation determined by the communication verification unit. If communication interruption or communication anomaly still occurs, a switching failure signal is generated and an alarm reminder is sent through the network. If normal communication is generated, a switching completion signal is generated.

[0025] A remote control method for a power distribution cabinet based on intelligent Internet of Things technology includes the following steps:

[0026] Step 1: Monitoring the operating environment information of the power distribution cabinet;

[0027] Step 2: Analyzing and warning the operating environment information;

[0028] Step 3: Executing the action signal of the power distribution cabinet and feeding back the execution result;

[0029] Step 4: Comparing the changes in the operating environment information to judge the normality of the network connection;

[0030] Step 5: Switching and correcting the network and judging the switching completion result.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. In the present invention, through the acquisition of the operating environment information and action feedback by the remote monitoring module, the dual acquisition of the environment information and its own action information in the power distribution cabinet is realized. Combining the data processing and fault prediction capabilities of the control center, the monitoring of environmental interference anomalies and its own action anomalies in the power distribution cabinet is realized, significantly improving the real-time performance and abnormal response accuracy of the power distribution cabinet status monitoring.

[0033] 2. In the present invention, through the continuous acquisition and data comparison of the power distribution cabinet information by the communication supervision module, the dynamic verification of the communication network of the power distribution cabinet is realized. When the channel quality deterioration is detected, the communication path is automatically switched, solving the problems of control failure caused by communication interruption and the problems of delayed or ineffective abnormal reporting in the traditional system.

[0034] 3. In the present invention, through the instruction linkage architecture of the execution feedback unit and the control center, the execution effect is synchronously verified after the action signal is generated, improving the success rate of remote control operations, and being able to give a timely warning reminder when the remote operation is not successful, avoiding the losses caused by the failure of the power distribution cabinet action execution.

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1:

[0040] Please refer to Figure 1 - Figure 2 As shown, the remote control system for power distribution cabinets based on intelligent Internet of Things technology includes a remote monitoring module, a control center, and a communication supervision module. The remote monitoring module is used to monitor the operation of the power distribution cabinet and execute feedback, obtain the operating environment information and action execution feedback, and send the operating environment information and action execution feedback to the control center. The remote monitoring module includes an operating environment monitoring unit and an execution feedback unit. Among them, the operating environment monitoring unit is used to monitor the operation of the power distribution cabinet, and the execution feedback unit is used to generate action execution feedback;

[0041] When the operating environment monitoring unit monitors the operation of the power distribution cabinet, the collected operating information includes the humidity rising and falling rate, the temperature distribution difference, and the internal temperature limit value;

[0042] The specific method is as follows: when the operating environment monitoring unit obtains the humidity rising and falling rate, it collects the humidity data in the power distribution cabinet through a sensor, synchronously records the humidity data and the time when the humidity data is collected, and calculates according to the time interval and the difference of the humidity data to obtain the humidity rising and falling rate;

[0043] The control center compares the humidity rising and falling rate with the set threshold. If the humidity rising and falling speed is greater than the set threshold, a normal ventilation signal is generated. If the humidity rising and falling rate is less than the set threshold, a ventilation abnormal signal is generated;

[0044] The operating environment monitoring unit collects the temperature data at different positions in the power distribution cabinet through a sensor, synchronously records the collection position, the collected temperature data, and the collection time, and selects the highest temperature data and the lowest temperature data from all the temperature data recorded at the same moment, and records them as the internal temperature limit value;

[0045] The control center compares the internal temperature limit value with the set temperature limit threshold range. If the internal temperature limit values are all within the temperature limit threshold range, a normal temperature signal is generated. If any one of the internal temperature limit values is outside the temperature threshold range, a temperature anomaly signal is generated;

[0046] The operating environment monitoring unit calculates the average value of the temperature data at all positions at the same moment to obtain the average temperature, and calculates the difference between the temperature data at each position and the average temperature, and records the difference as the temperature distribution difference;

[0047] The control center calculates the standard deviation of the temperature distribution difference to obtain the distribution characteristic value. If the distribution characteristic value is greater than the set threshold, a circulation anomaly signal is generated. If the distribution characteristic value is not greater than the set threshold, a circulation normal signal is generated.

[0048] The control center records the operation evaluation results of the power distribution cabinet with the ventilation normal signal, ventilation anomaly signal, temperature normal signal, temperature anomaly signal, circulation anomaly signal and circulation normal signal, and sends the power distribution cabinet evaluation results through the network;

[0049] The control center can generate and send a power distribution cabinet action signal to the execution feedback unit. After receiving the power distribution cabinet action signal, the execution feedback unit executes the power distribution cabinet action signal, and obtains the execution result after the execution is completed. The obtained execution result is compared with the power distribution cabinet action signal. If the comparison passes, an action completion signal is feedback. If the comparison fails, an action failure signal is feedback, and the action completion signal or action failure signal is sent to the control center. The control center can give a warning reminder according to the feedback action failure signal, so that the management personnel can timely discover the action execution faults existing in the power distribution cabinet and perform maintenance in time to reduce the impact scale caused by the power distribution cabinet faults.

[0050] The communication supervision module includes a communication verification unit and a communication switching unit. The communication supervision module verifies the communication situation of the power distribution cabinet through the communication verification unit, evaluates the communication situation according to the verification result, and completes the communication switching of the power distribution cabinet according to the evaluation result through the communication switching unit, and sends the communication switching result to the control center;

[0051] The method for the communication verification unit to verify and supervise through the information transmission between the power distribution cabinet and the control center is as follows:

[0052] Every certain period of time, the communication verification unit obtains the operating environment information through the operating environment monitoring unit, records the operating environment information, compares the operating environment information obtained multiple times, and obtains the change situation of the operating environment information. If the number of consecutive unchanged times of the operating environment information exceeds the set number, it is determined that the communication is abnormal. If the operating environment information cannot be obtained, it is determined that the communication is interrupted. Otherwise, it is determined that the communication is normal, and the communication interruption or communication abnormality is fed back to the communication supervision module;

[0053] After detecting communication interruption or communication abnormality, the communication switching unit obtains the currently running network mode through the communication supervision module, switches the network mode, generates a switching signal and sends it to the control center. After receiving the switching signal, the control center switches the sensor network in the power distribution cabinet, changes the information transmission network, and attempts to restore the network connection by changing the network, such as switching between dual-ring industrial networks, different signal frequency bands, switching between wired and wireless networks, and changing the network topology relay information transmission route;

[0054] After generating the switching signal, the communication switching unit simultaneously feeds back the switching signal to the communication supervision module. After receiving the switching signal, the communication supervision module monitors the communication situation determined by the communication verification unit. If communication interruption or communication abnormality is still generated, a switching failure signal is generated and an alarm reminder is sent through the network. If communication normality is generated, a switching completion signal is generated.

[0055] Embodiment 2:

[0056] Please refer to Figure 1 - Figure 2 As shown, the remote control method for the power distribution cabinet based on the intelligent Internet of Things technology includes the following steps:

[0057] Step 1: Matrix monitoring of various operating environment information in the power distribution cabinet, and statistical analysis of the monitored information;

[0058] Step 2: Classify the monitored operating environment information, perform data combination operations and threshold judgment analysis according to different classified operating environment information, and realize the early warning of the operating environment of the power distribution cabinet;

[0059] Step 3: Send the power distribution cabinet action signal through the network, execute it via the controller, and at the same time collect and feedback the execution result through the sensor, report the action execution situation according to the feedback result, and generate an early warning reminder when the action execution is abnormal;

[0060] Step 4: Continuously count the operating environment information, compare the change situation between the continuous data of the operating environment information, so as to reflect the authenticity of data transmission and judge whether the network connection is normal;

[0061] Step Five: When the network connection is abnormal, switch and correct the network, and re-verify the network connection after the switch is completed, and give a warning reminder according to the verification result.
