Embodiment 1
[0029] see figure 1 , The embodiment of the present invention provides an alarm device for an outdoor power cabinet, including: a card reader 101 , a door sensor 102 , a camera 103 , a microcontroller 104 and an alarm 105 .
[0030] Among them, the card reader is set on the outdoor power cabinet to read the user's identity information. When the door sensor detects that the door of the outdoor power cabinet is opened abnormally, the microcontroller triggers the camera to take pictures, and the alarm Sound the alarm.
[0031] It can be seen that when the outdoor power cabinet is damaged, the alarm can be reported in time, which reduces the probability of theft of the power cabinet, thereby ensuring the normal operation of the power system.
Embodiment 2
[0033] see figure 2 , The embodiment of the present invention provides an outdoor power cabinet alarm device, including: a card reader 101 , a door sensor 102 , a camera 103 , a microcontroller 104 , an alarm 105 and a short message sending and receiving device 106 .
[0034] Specifically, the short message sending and receiving device is electrically connected to the microcontroller, and the card reader is set on the outdoor power cabinet to read the user's identity information. When the door sensor detects that the door of the outdoor power cabinet is opened abnormally, the micro The controller triggers the camera to take pictures, and at the same time the alarm sounds and sends an alarm message to the preset device.
[0035] It should be noted that the preset device may be a certain device of the remote console, or may be a handheld electronic device of the maintenance operator, such as a mobile phone, a pager, and the like.
[0036] The purpose of this embodiment is to a...
Embodiment 3
[0038] see image 3 , The embodiment of the present invention provides an alarm device for an outdoor power cabinet, including: a card reader 101 , a door sensor 102 , a camera 103 , a microcontroller 104 , an alarm 105 and a power supply 107 .
[0039] Specifically, the power supply is electrically connected to the microcontroller and is used to supply power to the microcontroller. The working principle of the alarm device of the outdoor power cabinet in this embodiment is similar to the first embodiment, which is: the card reader is set on the outdoor power cabinet to read the identity information of the user. When the cabinet door is opened abnormally, the microcontroller triggers the camera to take pictures, and at the same time the alarm makes an alarm sound and sends an alarm message to the preset device.
[0040] It should be noted that the preset device may be a certain device of the remote console, or may be a handheld electronic device of the maintenance operator, s...
