Embodiment approach 1

[0023] Implementation mode 1: if figure 1 As shown, the outdoor power distribution cabinet waterproof system described in this embodiment includes a single-chip microcomputer control module, a water level monitoring module, a drainage control module, a GPS module, an infrared receiving module, a display module, a power management module, a GSM wireless information transmission module, an infrared Remote control and monitoring center client;

[0024] The single-chip control module can use stm32 series chips with high performance, low cost and low power consumption. The single-chip control module communicates with the GSM wireless information transmission module through the serial port, and transmits the data to the monitoring center client.

[0025] The water level monitoring module converts the water level signal into an electrical signal and transmits it to the MCU control module to obtain the water level information inside the power distribution cabinet; when the water level...

Embodiment approach 2

[0029] Implementation mode 2: if figure 2 As shown, in the outdoor power distribution cabinet waterproof system described in this embodiment, the water level monitoring module is composed of a sensitive capacitor, an operational amplifier and an analog-to-digital converter, and the two capacitive plates of the sensitive capacitor are placed vertically with the bottom of the power distribution cabinet. The water in the center of the two capacitor plates will affect the voltage on both sides of the capacitor plates. After the voltage is amplified by the second-stage operational amplifier, its voltage value conforms to the input range of the analog-to-digital converter, and is converted into a digital value by the analog-to-digital converter. The quantity is input to the single-chip microcomputer control module, and the single-chip microcomputer control module calculates whether there is currently accumulated water and the depth of the accumulated water.

[0030] The calibration...

Embodiment approach 3

[0035] Implementation mode 3: if image 3 As shown, in the outdoor power distribution cabinet waterproof system described in this embodiment, the power management module is composed of a backup lithium battery, a voltage conversion circuit, a lithium battery charging circuit, a single-chip microcomputer control module, other module power supply circuits, and a power distribution cabinet power switch circuit.

[0036] The power management module provides the required working power to the microcontroller control module and other modules, and controls the power on and off of the power distribution cabinet through the power switch circuit of the power distribution cabinet.

[0037] When there is no accumulated water in the power distribution cabinet or the accumulated water can be discharged normally, the power switch of the power distribution cabinet is in the on state, and the power management module uses the voltage conversion circuit to convert the voltage of the power distribu...

Abstract

The invention discloses a waterproof monitoring and processing system for an outdoor power distribution cabinet, and belongs to the field of power distribution cabinets. A water level monitoring module is used for collecting water level information in a power distribution cabinet and transmitting the information to a single-chip microcomputer control module; and a drainage control module is controlled by the single-chip microcomputer control module and controls a motor to drain water in the power distribution cabinet. a GSM wireless information transmission module is used for remote information transmission and can transmit the water level, the position and emergency power-off information received by the single-chip microcomputer control module to a monitoring center; a power supply management module maintains the power supply of the whole system and can cut off the power supply of the power distribution cabinet when drainage fails to prevent irreversible damage to circuits in the power distribution cabinet; a monitoring center client can check the water level and geographical position information of different power distribution cabinets in real time and receive emergency power-offinformation. The design of the outdoor power distribution cabinet waterproof system is realized so that the power distribution cabinet installed in the outdoor humid environment is enabled to have the functions of accumulated water monitoring and automatic drainage.

Description

technical field [0001] The invention relates to a waterproof monitoring and processing system for an outdoor power distribution cabinet, which belongs to the field of power distribution cabinets. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] The classification...
