Problems solved by technology

The maintenance and debugging of this industrial I / O board and industrial output board is time-consuming and laborious, and it is necessary to reconnect the industrial I / O board and industrial output board to the relay every time.
[0004] In addition, due to the limited drive and control capability of a single industrial I / O board and industrial output board for relays, when more relays are used, the number of industrial I / O boards and industrial output boards needs to be increased accordingly
At present, the motherboard of the main control computer has only a few card slots for the installation of I / O boards and industrial output boards, thus limiting the number of relays used

Abstract

The invention relates to a relay control apparatus, a control system and control methods. The relay control apparatus receives control signals output by a master control computer, and outputs driving signal to connect or disconnect the relay. An interface module transmits control signals for data communication among control apparatuses. A control module receives the control signals output by the interface module, verifies the integrity of the control signals and parses parsing control parameters. If the control signals are complete and the control parameters are valid, the control module outputs an execution signal for controlling on / off of the relay, and outputs a state signal indicating execution control signal to the master control computer by the interface module. The driving module receives execution signal and outputs the driving signal after amplifying the execution signal. The invention further provides a control method for the relay control apparatus, a relay control system employing the relay control apparatus, and a control method of the relay control system.

Description

technical field [0001] The invention relates to a control device, in particular to a control device for controlling a relay. The present invention also relates to a control method using the above control module, a control system using the above control device, and a control method of the control system. Background technique [0002] In the field of industrial control, for the control of the relay matrix, the existing method is to use the industrial I / O board and the industrial output board to complete the relay control. Wherein, the industrial I / O board and the industrial output board are installed in the expansion card slot of the main board of the main control computer, and are electrically connected to the relay through the interface of the industrial I / O board and the industrial output board. [0003] In the use of industrial I / O boards and industrial output boards, it is often necessary to maintain and debug the hardware of industrial I / O boards and industrial output b...
