When an error occurs in the power connection status, the working power supply is locked to prevent the system from being generated when the connection is incomplete. Destruction. The protection module 10 further includes: a latching unit 11, a display unit 12, and a switching unit 13. The display unit 12 may be a light emitting diode (LED).

Page 6 1225588 Case No. 9137541 Amendment V. Invention Description (3) It is composed and connected to a standby power source SB. This standby power source SB is a standing standby power source (Standby ρ 〇wer) in the information processing system. When the subsystem When the power supply connection status with the information processing system is incomplete, the standby power supply SB is transmitted to the ground terminal G through the display unit 12 to make the display unit 12 emit a bright light to display its abnormal state, and the latch unit 11 is a A Programmable Logic Controller (PLC) is used to control the working power. When the power connection status of the subsystem is normal, a switching signal is sent to the switching unit 1 3, and the switching unit 13 can be a transistor (Transistor). ), And is connected to the latch unit 11 and the display unit 12. When the switching unit 13 receives the switching signal, the switching causes the light of the display unit 12 to go out. The detection module 20 is connected to the protection module 10 and can detect the electrical connection status of the subsystem. The detection module 20 is used to detect the status of the protection module 10, and when the power connection status of the subsystem is normal, the judgment method is based on the switching signal generated by the latching unit 11 as the basis. When all the power connection states are normal, the information processing system can be started, and at the same time, the status of the information processing system is transmitted to the power status display element 21 for display. If the detection module 20 detects that the electrical connection status of the subsystem is incomplete, the detection module 20 will turn off the power, regardless of whether the power start button 30 is activated. When the detection module 20 detects that the electrical connection status of the subsystem is complete, the detection module 20 waits for the power-on button 30 to start to turn on the power. Next, the method for detecting and protecting the connection state of the power supply according to the present invention is described in detail. Please refer to FIG. 2 for a flowchart of the method for detecting and protecting the connection state of the power supply according to the present invention. The method for detecting and protecting the power supply connection state of the present invention has the following

Page 7 1225588 _ Case No. 91137541 V. Description of the invention (4) The steps of the year / month / △ day correction process: first start the auxiliary power (step 2 0 0), and then the detection module 2 0 judges the information processing system. Whether the power button is turned on (step 210). If the power is not turned on, the detection module will continuously detect it. If the power button is turned on, determine whether the power connection status of each subsystem and interface is normal (step 2 2 0) If the power connection status of each subsystem is normal, the power status display element 21 displays the correct power connection status message (step 2 3 0). If the power connection status of each subsystem is abnormal, the power status display element 2 1 Display the power connection status error message (step 2 40).

Finally, the device for detecting and protecting the connection state of the power supply according to the present invention will be described with reference to an embodiment. Please refer to "Figure 3", which is an embodiment of the device for detecting and protecting the connection state of the power supply according to the present invention.

The device for detecting and protecting the connection state of the power supply of the present invention is set in an information processing system. The information processing system includes a complex array protection module 1 0 a to 1 0 η, which are respectively used for a display subsystem and an interface. When the power is connected to the information processing system, and when an error occurs in the power connection status, the working power supply is locked to prevent damage caused by starting the system when the connection is incomplete, and it is connected to the standby power supply SB to lock the power supply. When the user presses the power start button 30, the present invention detects the power connection status between the information processing system and each subsystem and interface. If the power connection status of any subsystem is incomplete, then the sub-system is connected. The system's protection modules 10 a to 1 0 η will send a display message to notify the user, and each protection module 1 0 a to 1 0 η will also send its status to the detection module 20 for integration, if all The power connection status of the subsystems is very good. A green light is displayed on the power status display element 21 to indicate that the power connection status is good, and the information processing system program is started. If the power connection status of some subsystems is incomplete, Power
