Abstract: The relay safety system provided by the present invention includes a relay, an emergency stop device, a trigger detection circuit, a sticking detection circuit, and a power-off circuit. The emergency stop device is used to generate an emergency stop signal. The trigger detection circuit connects the relay and the emergency stop device, and is used to convert the emergency stop signal into a trigger signal. The sticking detection circuit is connected to the trigger detection circuit and the relay, and is used to detect the sticking signal generated by the relay, and generate a power-off signal according to the trigger signal and the sticking signal. The power-off circuit is connected to the emergency stop device, the relay and the sticking detection circuit, and receives the power-off signal, and disconnects the power of the relay according to the power-off signal.

Abstract: The teaching equipment of an electromechanical system provided by the present invention is used to connect an emergency stop loop of electromechanical equipment, including a multi-stage key switch, an enabling switch and a safety control device. The multi-stage key switch is used to switch between a first mode and a second mode. The multi-stage key switch generates a switching signal during switching. The enabling switch is connected to the emergency stop loop. The safety control device is used to receive the switching signal. The safety control device includes a transient emergency stop circuit and a disconnection loop time. The safety control device triggers the emergency stop loop to enter the emergency stop state according to the switching signal. The emergency stop state includes that the transient emergency stop circuit interrupts the emergency stop loop until the disconnection loop time is up.
