The other end of the push-button switch S is grounded through the third resistor R3.

[0044] The working principle of the above embodiment is as follows: when battery 5 is not lost, battery 5 presses and closes the button switch S, the base of the first NPN transistor QN1 is grounded through the button switch S and the third resistor R3, and the first NPN transistor QN1 is turned off. The control module receives a high-level signal through the collector of the first NPN transistor QN1 and determines that battery 5 is present.

The remote control system is set up in the main control room, so that the staff in the main control room can promptly discover that battery 5 in box 1 has been stolen.

[0050] According to some embodiments, the detection switch 9 includes a photosensitive switch D2, and the main board 6 is provided with a third detection circuit and a control module, such as...

[0052] The photosensitive switch D2 can be a photosensitive electronic component such as a photoresistor or a photodiode, and this application does not limit it.

[0053] The working principle of the above embodiment is as follows: when the battery 5 is not lost, the battery 5 covers the photosensitive switch D2 in the groove 10, the photosensitive switch D2 is turned off, the fourth NPN transistor QN4 is grounded through the eleventh resistor R11 and the twelfth resistor R12, the fourth NPN transistor QN4 is turned off, the base of the fifth NPN transistor QN5 is grounded through the fourteenth resistor R14, the fifth NPN transistor QN5 is turned off, the control module receives a high-level signal through the collector of the fifth NPN transistor QN5, and determines that the battery 5 exists.

[0055] According to some embodiments, such as Figure 2 As shown, the emergency lighting centralized power supply also includes a limit switch 11, which is located at the outlet edge of the first cavity 3.

[0056] When the cover 8 is closed, neither the display 7 nor the remote control system issues a notification; when the cover 8 is opened, the display 7 issues an audible and visual alarm and notifies the remote control system, which is located in the main control room, enabling personnel in the main control room to promptly detect the theft of batteries 5 from the enclosure 1. The dual detection of the limit switch 11 and the detection switch 9 enhances the anti-theft capability of the centralized power supply for emergency lighting.

[0057] When staff need to open the case 8 to remove battery 5, they enter a password on the display 7 to open the case 8.
