Industrial wireless remote control equipment capable of being actively and emergently stopped and method

Abstract

The invention relates to industrial wireless remote control equipment capable of being actively and emergently stopped and a method. The equipment comprises a remote control emitter, a remote control receiver, an emergent stop switch and a power control device, wherein the remote control emitter is used for emitting a wireless remote control signal; the remote control receiver is used for receiving the wireless remote control signal of the remote control emitter so as to control the operation of controlled equipment according to the wireless remote control signal; the emergent stop switch is disconnected normally and connected with the remote control emitter, and when the emergent stop switch is closed, the remote control emitter is promoted to send an emergent stop signal; the power control device is used for controlling the power of the controlled equipment and connected with the remote control receiver; the power control device is provided with a normally closed first connection point, and when the remote control receiver receives the emergent stop signal, the first connection point is disconnected so as to disconnect the power of the controlled equipment, thus the invention can shorten the stopping time of equipment out of control.

Description

technical field [0001] The invention relates to an industrial wireless remote control device, in particular to an industrial wireless remote control device and method capable of actively and urgently stopping the work of a controlled device when the device is out of control. Background technique [0002] In industrial equipment, there are usually two modes of operation of the equipment, one is long-term operation, and the other is inching operation. In the so-called long-term control mode, the electrical control circuit is equipped with a "self-protection" circuit. Once the operator presses a run button, the equipment starts running. Afterwards, if the operator releases the operation button, the equipment can still continue to operate. To stop the operation of the device, you need to press the "Stop" button again. [0003] In jog control mode, there is no "self-protection" circuit in the electrical control circuit. Once the operator presses a run button, the equipment st...

Problems solved by technology

This is a passive emergency stop method. Since this process takes 0.4 to 0.5 seconds, it is not conducive to the need to stop the out-of-control equipment as soon as possible in an emergency
