Misoperation controller and system of contact controlled actuator, method and application

Abstract

The invention discloses a malfunction controller, system, method and application of a contact actuator. By receiving a control command signal, if the control command signal is that at least two point signals act continuously or simultaneously within a set time, Then generate and send the corresponding action command to the corresponding contact actuator, otherwise maintain its non-action state; receive the action feedback information of the contact actuator in real time, if there is a contact actuator action, but does not receive the corresponding If there are at least two control command signals of point signals, a disconnection command is generated and sent to the corresponding contact actuator, otherwise, its action state is maintained. Adopting the anti-maloperation controller or control system provided by the present invention to control the mechanical equipment can effectively prevent the malfunction caused by the sticking of contact actuators such as contactors or the sticking of keys, and solve the safety problem.

Description

technical field [0001] The invention relates to a malfunction controller, system, method and application of a contact actuator. Background technique [0002] At present, there are contact actuators, such as contactors, relays, etc., which are mostly used in control circuits to control the corresponding equipment to perform various actions. The contact arc is too late to recover, and the problem of contact adhesion occurs. [0003] by figure 1 As an example, when the KM1 and other contactors are stuck, the phenomenon of being charged with executing the equipment will occur. For equipment with extremely high safety requirements, if contactor contact adhesion occurs, its action control will malfunction, which is very likely to cause major safety accidents or personal injury. The protective measures that are often used at present are to install multiple emergency stop buttons. Once a malfunction occurs, it will be controlled by emergency stop, but it still cannot avoid accide...

AI Technical Summary

Problems solved by technology

[0002] At present, there are contact actuators, such as contactors, relays, etc., which are mostly used in control circuits to control the corresponding equipment to perform various actions. The contact arc is too late to recover, and the problem of contact adhesion occurs

[0003] by figure 1 As an example, when contactors such as KM1 are stuck, there will be a phenomenon that the device is charged with random actions

For equipment with extremely high safety requirements, if contactor contact adhesion occurs, its action control will malfunction, which is very likely to cause major safety accidents or personal injury

At present, the commonly used protective measures are to install multiple emergency stop buttons. Once a malfunction occurs, it will be controlled by emergency stop, but it still cannot avoid accidents in time.
