Problems solved by technology

[0002] The existing backup power automatic input device is put into the backup power supply after the working power supply is powered off for a long time, the operation time is long, and the power equipment has a period of power failure time, which may affect the normal operation of the system
Moreover, most of the existing backup power automatic input devices use PLC-type control devices, plus an HMI human-machine interface to realize the display function. Such a structure is complex and costly, and the control speed and accuracy cannot be well guaranteed. The existing backup power automatic input device has the defects of slow action speed, complex structure, poor efficiency, high cost, poor operability, and single control mode, which can no longer meet the strict functional requirements in industrial production.

Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention is further described:

[0017] See attached figure 1 , 2 , the connection is to connect the power supply unit 1 with the CPU control unit 2, the display control unit 3, the input unit 4, the output unit 5, the analog unit 6, and the link unit 7. The power supply unit 1 is connected with other units and provides its working power. Both the CPU control unit 2 and the display control unit 3 use low-power and high-performance STM32F2 processors; the power supply unit uses AC and DC switching power supplies; each unit adopts a modular design , the CPU control unit 2, the input unit 4, the output unit 5 and the analog unit 6 realize the data transmission between each unit through the parallel bus on the link unit 7, and the CPU control unit 2 and the display control unit 3 through the link unit The serial bus on 7 realizes the data transmission between the units, the CPU control unit 2 and the communicati...

Abstract

The invention relates to a multi-functional relay and a control method thereof. The connection of the multi-functional relay is that a power supply unit is connected with a CPU (Central Processing Unit) control unit, a display control unit, an inlet unit, an outlet unit and an analog quantity unit through a link unit. The CPU control unit, the inlet unit, the outlet unit and the analog quantity unit are directly communicated through a parallel bus of the link unit, the CPU control unit and the display control unit are communicated in accordance with a certain protocol through a serial bus of the link unit, the CPU control unit and a communication unit are communicated through a parallel bus in the CPU control unit, the power supply unit and other units are connected through the link unit to supply a device with working power supply. Compared with the prior art, the multi-functional relay achieves an independent modular design, is more reliable and stable, easy to maintain, low in cost and high in real-time performance, has an operation recording function, and is a control device which can detect parameters of a power system in real time during the operation of the power system.

Description

technical field [0001] The invention relates to a multifunctional relay and a control method thereof, which relate to the technical field of electric power system intelligent control. Background technique [0002] The existing automatic switch-in devices for standby power supply are put into standby power supply only after the working power supply has been powered off for a long time. The operation time is long, and the power equipment has a period of power-off time, which may affect the normal operation of the system. Moreover, most of the existing backup power automatic input devices use PLC-type control devices, plus an HMI human-machine interface to realize the display function. Such a structure is complex and costly, and the control speed and accuracy cannot be well guaranteed. The existing automatic input device for backup power has the defects of slow action speed, complex structure, poor efficiency, high cost, poor operability, and single control mode, and can no lon...
