Abstract

The invention provides an emergency stop circuit, including an emergency stop switch, a relay control signal generation circuit, a relay circuit, a delay circuit and a processor, wherein the processor is used to send the first emergency stop signal of the emergency stop switch according to the user's request And / or the emergency stop switch reset signal; the emergency stop switch is used to receive the user's request to generate the second emergency stop signal of the emergency stop switch, and is also used to receive the emergency stop switch reset control signal to realize reset; the relay control signal generating circuit It is used to generate a relay control signal according to the switch reset signal, the first emergency stop signal or the second emergency stop signal; the delay circuit is used to delay through the second emergency stop signal and the emergency stop switch reset signal Generate the emergency stop switch reset control signal after hours. The invention can realize the switching, locking and restarting functions of the emergency stop switch.

Description

technical field [0001] The invention relates to the technical field of an emergency stop switch, and specifically relates to an emergency stop switch circuit and an emergency stop and reset method for the emergency stop switch. Background technique [0002] At present, according to the requirements of the national standard, the existing charging piles have the function of emergency stop button, and the specific specification requires that after the emergency stop switch is pressed, the charging will drop to the safe voltage range within a limited time, and it has the property of preventing misoperation . [0003] According to the investigation, most of the current emergency stop switches are contact switches, which cannot realize the property of preventing misoperation, and cannot realize the reset of the switch. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art, and provide an emergency stop switch circuit...
