Specifically, the controller is an industrial personal computer, the industrial personal computer is powered on and started up, and when the industrial personal computer detects that the power-on is completed, a first trigger signal for controlling the first switch element and the second switch element is generated. The first switch piece and the second switch piece can keep the access state after receiving the first trigger signal, and at the moment, the first power supply can supply power to the industrial personal computer and the load. It can be appreciated that an industrial personal computer is coupled to the load, the industrial personal computer being capable of controlling the operation of the load.

Meanwhile, the first switch piece also receives the first trigger signal and keeps a closed state, and the first power supply is transmitted to the load through the first switch piece, so that power is supplied to the load. When the industrial personal computer is normally shut down, the industrial personal computer does not continuously send the first trigger signal to the first switch piece and the second switch piece, the second switch piece loses self-locking, countdown is started, and the first switch piece is disconnected to enable the load to be powered off.

In particular, the power supply circuit has a voltage regulating function, enabling the controller to operate at a suitable voltage. The power supply circuit also has a separate power supply function, and can supply power to the controller under the condition that the first power supply does not supply power to the controller.

In some embodiments, the controller is an industrial personal computer. After the industrial personal computer is started, the current signal at the second power supply is continuously detected, and the current signal at the second power supply is continuously detected, so that the second power supply is stable in power supply to the industrial personal computer. When no current signal is detected at the second power supply, the shutdown step is executed, electricity is taken from the energy storage element, and the energy storage element supplies power to the industrial personal computer to ensure that the industrial personal computer enters a shutdown program and ensure the running stability.
In other embodiments, when the starting of the industrial personal computer is not completed, the first power supply does not supply power to the second power supply any more, and at the moment, the industrial personal computer cannot detect a current signal at the second power supply because the starting of the industrial personal computer is not completed, so that the industrial personal computer is powered down along with the second power supply. It can be understood that because the industrial personal computer is not started at the moment, no program needs to be shut down, and the industrial personal computer can be directly powered off and shut down.
In one possible design, the power supply system further includes: and the second end of the third switching piece is configured as a signal output end and used for sending the first trigger signal to the first switching piece and the second switching piece.

When the current flowing to the fourth switching element is larger than the first set current value, the fourth switching element is in an off state, and the current cannot continuously flow. When the current flowing to the fuse is larger than the second set current value, the fuse is blown to disconnect the circuit, and the current does not continue to flow. Wherein the first set current value is smaller than the second set current value.

The user can control the on-off state of the second switch piece through the fifth switch piece. When a user needs to start the controller, the fifth switch piece is directly operated, and the second switch piece can be in a closed state, so that current can flow to the controller through the second switch piece, and the power supply effect of the controller is achieved.
In some embodiments, the fifth switching element is a self-resetting switch and the second switching element is a time-delay relay. The self-reset switch is directly connected with the control end of the delay disconnection relay, a user can send a second trigger signal to the delay disconnection relay by triggering the self-reset switch to enable the delay disconnection relay to be in a closed state, the delay disconnection relay starts countdown after being closed, and in the countdown process, the delay disconnection relay receives the first trigger signal and is in a self-locking state, namely the delay disconnection relay continuously keeps a path state.
