[0002] With the rapid development of urban construction, power cable trenches and joint wells, as an important infrastructure of the power system with a large stock, it is imperative to conduct online monitoring on them.

[0003] The inventor found that in the urban distribution of power cable trenches and joint wells, they have the characteristics of large quantity, relatively independent and scattered, and there are no power supply and wired communication conditions on site, making it difficult to implement unified management and monitoring, which brings inconvenience to the monitoring of power cable trenches and joint wells. In particular, the independent power supply batteries of the monitoring devices for power cable trenches and joint wells are in a trusteeship state, and the continuous power supply time is short, which brings a huge workload to the later maintenance of the monitoring devices for power cable trenches and joint wells. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a power supply management system, a power supply and a method for a monitoring device of a trench and a joint well.

[0007] The main control unit is used for performing power management scheduling according to the detection and judgment results;

[0008] The two monitoring units are used for respectively detecting and judging the power supply outputs of the first type of devices and the second type of devices in the monitoring device of the trench and the joint well; when judging the output power supply of the first type of devices, when the output current is greater than a preset value, an automatic stop power supply instruction is sent through the main control unit, and when the output current is less than the preset value, an automatic resume power supply instruction is sent through the main control unit; when judging the output power supply of the second type of devices, the power supply cycle is judged, and the main control unit determines whether to send a continue power supply instruction according to the judged power supply cycle; wherein, the power consumption of the first type of devices is less than that of the second type of devices.

[0009] Further, the main control unit is also connected to a power management unit; the power management unit is used for monitoring the remaining power, monitoring the output current, and monitoring the output voltage.

[0010] Further, the main control unit is also connected to a clock unit; the clock unit is used to provide time for the main control unit so that the main control unit can judge the current battery power usage situation.

[0011] Further, a coulomb meter is used to calculate the input power and output power of the power supply, and the power consumption is calculated according to the working time output by the real-time clock.

[0012] Further, the main control unit is connected to a monitoring platform through a communication unit.

[0017] Further, when judging the output power supply of the first type of device, if it is detected that the output current does not exceed the preset value, the power supply output is controlled, and if it is detected that the output current exceeds the preset value, the power supply is only output within the set working time, and the output is turned off after exceeding the set working time.

[0018] Further, when judging the output power supply of the second type of device, clock detection is performed to detect whether the power supply cycle has arrived. If so, the intermittent power supply port is opened for output, otherwise, the clock detection continues; after the intermittent power supply port is opened for output, it is closed after working for the set duration, and then the clock detection process is entered again.

[0029] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0030] Embodiment 1:

[0031] As Figure 1As shown in the figure, this embodiment provides a power supply management system for trench and joint well monitoring devices, including a main control unit, and a power management unit, a clock unit, two monitoring units, a communication unit, a battery unit, and a temperature unit connected to the main control unit;

[0032] The main control unit is configured as the MCU of the intelligent power supply device and is used for power management scheduling according to the detection and judgment results; the main control unit can also be used for processing data and transmitting data.

[0033] The two monitoring units are used to respectively detect and judge the power supply outputs of the first-class devices and the second-class devices in the trench and joint well monitoring devices; when judging the output power supply of the first-class devices, when the output current is greater than the preset value, an automatic stop power supply outward instruction is issued through the main control unit, and when the output current is less than the preset value, an automatic resume power supply outward instruction is issued through the main control unit; when judging the output power supply of the second-class devices, the power supply cycle is judged, and the main control unit determines whether to issue a continue power supply outward instruction according to the judged power supply cycle; among them, the power consumption of the first-class devices is less than that of the second-class devices;

[0034] Specifically, the two monitoring units use two external outputs of the power supply. One is a constant power supply output port, which is used to connect to the first-class low-power devices, devices with a low power consumption between 0 and 20 mA. When the output current is greater than the set value, the power supply outward is automatically stopped; when the output current is less than the set value, the power supply outward is automatically resumed; the other is a controllable output port, which is used to connect to the second-class devices with larger power consumption, devices with a low power consumption between 20 mA and 200 mA. The power supply cycle and the power supply duration can be set, and the power supply is carried out according to the power supply cycle.

[0035] The power management unit is used for monitoring the remaining power, monitoring the output current, and monitoring the output voltage, and accurately calculating the remaining power according to the monitoring of the output current and the output voltage.

[0036] The clock unit is used to provide accurate time for the main control unit so that the main control unit can judge the current battery power usage situation. Specifically, in some other embodiments, a coulomb meter can be used to calculate the input power and output power of the power supply, and the power consumption can be calculated according to the working time output by the real-time clock.

[0037] The communication unit is used for 485 communication between the main control unit and the monitoring platform to realize the online monitoring function of the intelligent power supply device itself;

[0038] The battery unit is the battery pack of the device; the temperature unit is used for temperature monitoring inside the device. It can be understood that the temperature unit is a temperature sensor, which can be set in the trench and joint well to detect the overall environmental temperature, or set on the monitoring equipment in the trench and joint well to detect the temperature of the monitoring equipment, or also set in the power supply management system to monitor its temperature.

[0039] Through the power supply management system of the monitoring equipment in the trench and joint well in this embodiment, intelligent management of the power supply in the power cable trench and joint well can be realized, so as to provide power support for the online or semi-offline monitoring equipment of cables, joints and the environment for three to five years.

[0040] Embodiment 2:

[0041] This embodiment provides a power supply management method for the monitoring equipment in the trench and joint well, which adopts the power supply management system of the monitoring equipment in the trench and joint well as described in Embodiment 1, including:

[0042] Used to respectively detect and judge the power supply output of the first type of equipment and the second type of equipment in the monitoring equipment of the trench and joint well; when judging the output power supply of the first type of equipment, when the output current is greater than the preset value, automatically stop supplying power outward, and when the output current is less than the preset value, automatically resume supplying power outward; when judging the output power supply of the second type of equipment, determine whether to continue supplying power outward according to the judged power supply cycle.

[0043] When judging the output power supply of the first type of equipment, if it is detected that the output current does not exceed the preset value, control the power supply output; if it is detected that the output current exceeds the preset value, the power supply is only output within the set working time, and the output is closed after exceeding the set working time.

[0044] When judging the output power supply of the second type of equipment, perform clock detection to detect whether it reaches the power supply cycle. If so, open the intermittent power supply port to output, otherwise continue clock detection; open the intermittent power supply port to output, close it after working for the set duration, and then enter the clock detection process again.

[0045] The method for managing the remaining power is to accurately calculate the input and output power of the battery using a coulomb meter, and accurately calculate the consumed power according to the working time output by the real-time clock. Total power - consumed power = remaining power.

[0046] When it is monitored that the temperature inside the device reaches the warning value or alarm value, send a warning signal or alarm signal to the platform in time to notify the platform management personnel.

[0047] Embodiment 3:

[0048] A power supply for a monitoring device of a pipe trench and a connection well adopts the power supply management system for the monitoring device of the pipe trench and the connection well as described in Embodiment 1.
