The connecting plate 33 serves to connect and support the connecting base 20, and a certain gap is created between the connecting base 20 and the cabinet body 30. The connecting base 20 is positioned near the opening of the cabinet body 30 to facilitate connection of the alarm module 10 thereto.

[0035] Furthermore, a switch device 32 and a handle 34 are provided in the cabinet 30, and the switch device 32 can be manually opened and closed by the handle 34. Through holes are provided on the top and bottom of the cabinet 30 to facilitate wiring so that the switch cabinet can be connected to the mains, and the connection socket 20 is connected to the power supply line in the switch cabinet.

[0036] When the cabinet door 31 is closed, the alarm module 10 is connected with the connecting seat 20 to be in conduction, at this time, when the switch device 32 or the main circuit fails or reaches the set threshold value, the alarm signal can be directly sent out by the alarm module 10; when the cabinet door 31 is in an open state, the switch is in a disconnected state or a low risk state, that is, when the staff is overhauled or maintained. After the cabinet door 31 is opened, the alarm module 10 is disconnected with the connecting seat 20, that is, they do not contact each other, which achieves the effect of energy saving to a certain extent.

In particular, the control signal can also be transmitted through the conductive PIN point 15, that is, the control module is controlled through special instructions, such as changing the color of the indicator light bead or the vibration frequency of the buzzer.

[0039] Specifically, the first kind of data transmission is actually the transmission of electrical signals between the conductive PIN point 15 and the connecting seat 20, which can be analog signals or digital signals, depending on the design and needs of the system; and the second kind of data transmission is to obtain the switch state information by the judgment module 21, and then transmit the data signal through the communication between the first wireless communication module and the second wireless communication module. Optionally, the first communication module and the second wireless communication module can adopt one of Bluetooth, IrDA (infrared data transmission), ZigBee and WiFi.

[0040] In the embodiment, the alarm module 10 adopts an indicator light and a buzzer, wherein the lamp bead of the indicator light is provided with a three-color lamp bead capable of changing RGB values, that is, the basic function of the indicator light in a general state can be realized by system control, and different colors are used to represent various states. Then in a special case, the alarm is realized by changing the flashing frequency and color of the lamp bead, that is, a red light that constantly flashes. The buzzer is used to make the alarm signal more far and eye-catching.

[0041] Further, the shell of the alarm module 10 is composed of a base 11 and a cover 12, the base 11 is in a cylindrical structure as a whole, and the cover 12 is provided with a guide block 122 integrally formed on one side of the cover 12. In particular, in order to facilitate the alarm module 10 to be conveniently fitted on the cabinet door 31, a fixing ring 13 is further sleeved on the end of the cover 12.

[0042] The fixing ring 13 is made of silica gel or rubber material, that is, when the alarm module 10 passes through the cabinet door 31, the alarm module 10 is fixed by sleeving the fixing ring 13. The cabinet door 31 is provided with a circular hole 311 for the alarm module 10 to pass through, and a guide groove 312 matched with the guide block 122 is arranged on the top of the circular hole 311. The fixing ring 13 and the cover 12 are in interference fit, and the connecting end of the fixing ring 13 and the cover 12 is a deformation area 132, which is slightly smaller in diameter than the diameter of the cover 12. When the fixing ring 13 is sleeved on the cover 12, the pressure on the cover 12 increases, so that the friction between them is greater, further enhancing the connection effect.

Then in special cases, the alarm is realized by changing the flashing frequency and color of the lamp bead, that is, the red light flashes constantly. The buzzer is to make the alarm signal be transmitted farther and more eye-catching.

[0050] Further, the shell of the alarm module 10 is composed of a base 11 and a cover 12 which is threadedly connected with the base 11, the base 11 is in a cylindrical structure, and the cover 12 is provided with a guide block 122 on one side, in particular, in order to facilitate the alarm module 10 to be conveniently fitted on the cabinet door 31, the end of the cover 12 is further provided with a fixing ring 13.
