Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0038] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0039] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0040] Figure 1This is a schematic diagram of the structure of a DC power supply screen temperature monitoring system provided by an embodiment of the present disclosure. Figure 1 The DC power supply panel includes: a rectifier module 200 and a filter module 201 connected in sequence. The DC power supply panel temperature monitoring system 100 includes:

[0041] A first voltage sensor 101 , a second voltage sensor 102 , a voltage comparator 103 , a controller 104 , a temperature sensor module 105 , and a data processor 106 .

[0042] The first voltage sensor 101 is used to be connected to the output end of the rectifier module 200 of the DC power supply panel. The second voltage sensor 102 is used to be connected to the output end of the filter module 201 of the DC power supply panel. The first voltage sensor 101 and the second voltage sensor 102 are both connected to the voltage comparator 103.

[0043] The voltage comparator 103 is connected to the controller 104 . The controller 104 is connected to the temperature sensor module 105 . The temperature sensor module 105 is connected to the data processor 106 .

[0044] In this embodiment, the first voltage sensor 101 and the second voltage sensor 102 are both sensors for measuring voltage information in a circuit and converting the information into an electrical signal or other forms of information output. The voltage comparator 103 is an electronic device that can perform logical judgment based on two input voltage values, usually including two input terminals and one output terminal, and its logical judgment method is equivalent to an AND gate circuit. The temperature sensor module 105 is composed of a plurality of sensors that can sense temperature information and convert it into a usable output signal. The controller 104 is an electronic device or component for managing, commanding and regulating other devices or systems, thereby realizing control of other devices. The data processor 106 is a chip that saves, analyzes and processes received data with data calculation as the center.

[0045] In this embodiment, since the DC power supply panel includes a rectifier module and a filter module, wherein the input end of the rectifier module is usually connected to an AC power supply to convert AC power into DC power, and its output end is connected to a filter module, and the filter module further filters the DC power to reduce power ripples and noise, and the output end of the filter module is connected to an external load to provide power for each external load. Since there may be errors in the output voltages of these two modules in practical applications, the output voltages of different modules of the DC power supply panel can be monitored separately by setting two voltage sensors. Among them, the first voltage sensor 101 is used to connect to the output end of the rectifier module 200 of the DC power supply panel, directly collect the voltage data output by the rectifier module 200 of the DC power supply panel, and transmit the collected data to the voltage comparator 103. The second voltage sensor 102 is used to connect to the output end of the filter module 201 of the DC power supply panel, collect the output voltage after filtering, and also transmit the collected data to the voltage comparator 103. After receiving the two voltage acquisition values, the voltage comparator 103 compares and analyzes the two acquisition voltages according to the pre-set warning value. Only when both voltage values ​​exceed the warning value, it proves that the DC power supply panel is in a high-intensity output state, which may generate a lot of heat and cause the temperature to rise, thus posing a potential high-temperature warning risk. Therefore, the voltage comparator 103 outputs a corresponding temperature monitoring signal to the controller 104.

[0046] The controller 104 is connected to the temperature sensor module 105. After receiving the corresponding temperature monitoring signal, the controller 104 sends a corresponding control signal to the temperature sensor module 105 to start the temperature sensor module 105 to start monitoring. In addition, the temperature sensor module 105 is connected to the data processor 106. The temperature sensor module 105 uploads the collected data to the data processor 106 in real time, and the data processor 106 performs data analysis to determine whether there is a potential safety fault in the current DC power supply screen. When the voltage data monitored by the first voltage sensor 101 and the second voltage sensor 102 recovers to below the warning value, the voltage comparator 103 can send a corresponding stop monitoring signal to the controller 104, and the controller 104 controls the temperature sensor module 105 to stop the temperature monitoring work.

[0047] From the above, it can be concluded that the present embodiment can determine the actual working output state of the DC power supply panel by monitoring the voltage thereof, thereby utilizing the controller 104 to implement monitoring and control of the temperature sensor module 105, so as to cope with the flexibly changing temperature monitoring requirements, improve the system application flexibility and monitoring efficiency, and also save energy and achieve an environmental protection effect.

[0050] The plurality of temperature sensors 107 are respectively used to be connected to the plurality of external power distribution units 300 in a one-to-one correspondence. The plurality of temperature sensors are all connected to the data processor 106 .

[0051] In this embodiment, since the DC power supply panel includes a main output unit and a plurality of power distribution units, the temperature sensor module 105 may include a plurality of temperature sensors 107, wherein each temperature sensor is used to be connected to a corresponding external power distribution unit 300, thereby realizing distributed temperature monitoring of the DC power supply panel. Among them, the temperature sensor is a sensor that can sense temperature information and convert it into a usable output signal. According to the monitoring data of each temperature sensor, the monitored data can be uploaded to the data processor 106, and the data processor 106 centrally analyzes and processes all the data, so as to better judge the temperature state of the current DC power supply panel.

[0052] From the above, it can be concluded that this embodiment can configure multiple temperature sensors 107 according to actual conditions to achieve distributed temperature monitoring of each external distribution unit 300, and obtain the temperature monitoring values ​​of different distribution units more intuitively and clearly, thereby improving the accuracy of temperature monitoring and reducing the accident rate.

Among them, the relay module includes multiple relays, the controller 104 is connected to the multiple relays, and each relay is respectively connected to a temperature sensor corresponding to control the switch of each temperature sensor. When the controller 104 sends a corresponding control signal, the multiple relays control the corresponding multiple temperature sensors 107 to start according to the signal. The controller 104 can realize the centralized control process of multiple temperature sensors 107 through multiple relays. When the controller 104 receives a stop monitoring signal from the voltage comparator 103, it can control multiple relays to turn off the corresponding temperature sensors to stop the temperature monitoring work.

[0058] It can be concluded from the above that the present embodiment can better realize the control process of multiple temperature sensors 107 through multiple relays, thereby ensuring that the multiple temperature sensors 107 change their working states in time according to real-time changing monitoring requirements, thereby improving the control flexibility of the system.

Among them, multiple temperature sensors 107 are connected to the positioning module, and the positioning module obtains the positioning information of each temperature sensor. The positioning module is connected to the data processor 106, and the positioning module sends the positioning information of each temperature sensor to the data processor 106.

[0063] The temperature warning value is set in advance by the staff. When the data processor 106 analyzes the collected data of each temperature sensor and obtains data that exceeds the temperature warning value, that is, temperature abnormality occurs, the specific location of each temperature sensor can be determined through the positioning information of the temperature sensor, so as to find the corresponding external distribution unit 300. By adjusting the output power of the DC power supply panel, the temperature fault of the distribution unit can be eliminated in time to prevent the occurrence of safety accidents in advance.
