Problems solved by technology

For the system with master-slave input, the reliability of the system is improved, but only when the master input is abnormal, the backup input will be activated. work, purely on standby
For the main input, long-term operation will accelerate the end of its life. For the standby input, the long-term standby state will also cause factors such as the aging of various devices to affect its performance, and it has not been fully used, resulting in redundant resources. waste
For the system with master-slave input, at present, software program is mainly used to realize switching control, which can realize various controls, and the control methods are flexible and diverse, but the program is complicated

Embodiment Construction

[0034] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0035] An interlocking device of the present invention comprises a first device, a second device, a switch, first to fifth control switches, and a load. The first device and the second device are respectively connected via the normally open contacts of the first control switch , the normally open contact of the second control switch is connected to the load to form the main circuit, and also includes a control circuit, which includes the first to third branches connected to the first power supply and the second power supply The fourth and fifth branches between the two ends;

[0036] The first branch circuit includes a fault dry contact of the first device and a control coil of a third control switch connected in series;

[0037] The second branch circuit includes a fault dry contact of the second device and a control coil of the fourth ...

Abstract

The invention relates to an interlocking apparatus and a control method thereof. A relay and a switch is employed. When one input device fails, input signals are provided by automatic switching to the other device. When two input devices are faultless, any device is manually selected to work through a selector switch. A redundant device works alternatively as master / slave device, thereby effectively preventing the phenomenon that one device works for a long time, and the other device does not work for a long time, and maximally utilizing system resources. The apparatus has stable function, control is simple and the cost is low.

Description

technical field [0001] The invention relates to a redundant circuit control device, in particular to an interlock device and a control method thereof. Background technique [0002] In order to improve the reliability of the load and prevent the failure of a single input from affecting the reliable operation of the equipment, in the prior art, the general practice is to provide the main input to the load and at the same time equip a backup input with the same performance as the main input to cooperate with the control device Or use software control so that when the main input is normal, the redundant backup input does not work, and when the main input fails, it automatically switches to the backup input to ensure the operation of the load. For the system with master-slave input, the reliability of the system is improved, but only when the master input is abnormal, the backup input will be activated. Work, purely on standby. For the main input, long-term operation will accel...
