[0032] Embodiment 1

[0033] As Figures 1-5 shown, this embodiment discloses a switch cabinet with an alarm system, which includes a cabinet body 30, a cabinet door 31 rotatably arranged on the cabinet body 30, and an alarm system. The alarm system includes a connection seat 20 and an alarm module 10 installed on the cabinet door 31, and the connection seat 20 is arranged in the box through a connecting plate 33. The connecting plate 33 is in a Z-shaped structure, one end of which is fixed to the connection seat 20 by bolts, and the other end is connected to the cabinet body 30 by bolts. The connecting plate 33 plays a role in connecting and supporting the connection seat 20, and there is a certain gap between the connection seat 20 and the cabinet body 30. The connection seat 20 is arranged near the opening of the cabinet body 30, which is convenient for the alarm module 10 to be connected thereto.

[0034] Furthermore, a switching device 32 and a handle 34 are also arranged in the cabinet body 30, and the switching device 32 can be manually opened and closed through the handle 34. Through holes are provided at both the top and the bottom of the cabinet body 30 for wire routing to connect the switch cabinet to the mains, and the connection seat 20 is connected to the power supply line in the switch cabinet.

[0035] When the cabinet door 31 is closed, the alarm module 10 is connected and conducted with the connecting seat 20. At this time, when the switch device 32 or the main circuit fails or reaches the set threshold, an alarm signal can be directly sent out through the alarm module 10; when the cabinet door 31 is in the open state, in this case, most switches are in the off state or low-risk state, that is, during maintenance or repair by staff. After the cabinet door 31 is opened, the alarm module 10 is disconnected from the connecting seat 20, that is, they do not contact each other, achieving a certain degree of energy-saving effect.

[0036] Specifically, to achieve the above purpose, one end of the alarm module 10 is provided with a conductive PIN point 15, and the connecting seat 20 is provided with a power supply module 22, and the power supply module 22 is provided with a contact point 221 for the conductive PIN point 15 to cooperate with to supply power to the alarm module 10. That is, the alarm module 10 contacts the contact point 221 of the power supply module 22 through the conductive PIN point 15 to supply power to the alarm module 10 and transmit data. Optionally, the alarm module 10 is one or a combination of an indicator light, a buzzer, and a vibrator, and the alarm module can be combined or selected according to actual needs.

[0037] The connecting seat 20 is also provided with a judgment module 21 and a first wireless communication module, and the alarm module 10 is provided with a second wireless communication module. That is, in the alarm system, there are two communication methods between the alarm module 10 and the connecting seat 20: wireless communication and conductive PIN point 15 contact communication. The switch state information data is obtained, and then the judgment module 21 analyzes whether a specific value reaches the preset threshold. If it reaches, an alarm signal is sent to the alarm module 10 for alarm. Particularly, a 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 beads or the vibration frequency of the buzzer.

[0038] Specifically, the first data transmission is actually the transmission of electrical signals between the conductive PIN point 15 and the connecting seat 20. These electrical signals can be analog signals or digital signals, depending on the system design and requirements; the second data transmission is to obtain the switch state information through the judgment module 21, and then the data signal is transmitted 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 Association), ZigBee, and WiFi.

[0039] In this embodiment, the alarm module 10 uses an indicator light and a buzzer. The lamp beads of the indicator light are three-color lamp beads with changeable RGB values. That is, through the system control, the indicator light can realize the basic functions of the indicator light under normal conditions, and different colors are used to represent various states. Then, in special cases, the alarm is realized by changing the flashing frequency and color of the lamp beads, that is, the continuously flashing red light. The buzzer is to make the alarm signal be transmitted farther and more prominently.

[0040] Further, the housing of the alarm module 10 is composed of a base 11 and a cover 12. The base 11 is a cylindrical structure as a whole, and a guide block 122 integrally formed with the cover 12 is provided on one side of the cover 12. In particular, in order to facilitate the alarm module 10 to be easily assembled on the cabinet door 31, a fixing ring 13 is also sleeved at the end of the cover 12.

[0041] The fixing ring 13 is made of silicone or rubber as a whole. 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. A round hole 311 for the alarm module 10 to pass through is provided on the cabinet door 31, and a guide groove 312 for cooperating with the guide block 122 is provided at the top of the round hole 311. An interference fit exists between the fixing ring 13 and the cover 12, and one end of the fixing ring 13 connected to the cover 12 is a deformation area 132, and its diameter is slightly smaller 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 frictional force between the two is greater, further enhancing the connection effect.

The connecting plate 33 is a Z-shaped structure, one end of which is fixed to the connection seat 20 by bolts, and the other end is connected to the cabinet body 30 by bolts. The connecting plate 33 plays a role in connecting and supporting the connection seat 20, and there is a certain gap between the connection seat 20 and the cabinet body 30. The connection seat 20 is arranged near the opening of the cabinet body 30 to facilitate the connection between the alarm module 10 and it.

[0044] When the cabinet door 31 is closed, the alarm module 10 is connected and conducted with the connection base 20. At this time, when the switch device 32 or the main circuit fails or reaches the set threshold, an alarm signal can be directly sent out through the alarm module 10 to the outside; while when the cabinet door 31 is in the open state, in this case, half of the switches are in the off state or low-risk state, that is, during maintenance or repair by the staff. After the cabinet door 31 is opened, the alarm module 10 is disconnected from the connection base 20, that is, they do not contact each other, achieving the effect of energy saving to a certain extent.

[0045] Specifically, to achieve the above purpose, one end of the alarm module 10 is provided with a conductive PIN point 15, and the connection base 20 is provided with a power supply module 22, and the power supply module 22 is provided with a contact point 221 where the conductive PIN point 15 cooperates to supply power to the alarm module 10. That is, the alarm module 10 contacts the contact point 221 of the power supply module 22 through the conductive PIN point 15 to supply power to the alarm module 10 and conduct data transmission. Optionally, the alarm module 10 is one or a combination of an indicator light, a buzzer, and a vibrator, and the alarm module can be combined or selected according to actual needs.

[0046] The connection base 20 also includes a judgment module 21 and a first wireless communication module, and the alarm module 10 is provided with a second wireless communication module. That is, in this alarm system, there are two communication methods between the alarm module 10 and the connection base 20: wireless communication and PIN needle contact communication.

[0047] Specifically, the first data transmission is actually the transmission of electrical signals between the conductive PIN point 15 and the connection base 20. These electrical signals can be analog signals or digital signals, depending on the system design and requirements; while the second data transmission is to obtain the switch state information through the judgment module 21, and then conduct data signal transmission through the communication between the first wireless communication module and the second wireless communication module. Optionally, the first wireless communication module and the second wireless communication module can adopt one of Bluetooth, IrDA (Infrared Data Association), ZigBee, and WiFi.

[0048] In this embodiment, the alarm module 10 adopts an indicator light and a buzzer. The lamp beads of the indicator light are provided with three-color lamp beads that can change RGB values. That is, through system control, the basic functions of the indicator light can be realized in the normal state, and different states can be represented by different colors. Then, in special cases, an alarm is realized by changing the flashing frequency and color of the lamp beads, that is, continuously flashing red light. The buzzer is used to make the alarm signal be transmitted farther and more prominently.

[0049] Furthermore, the housing of the alarm module 10 is composed of a base 11 and a cover 12. The base 11 is a cylindrical structure as a whole, and a guiding block 122 is provided on one side of the cover 12. In particular, in order to facilitate the installation of the alarm module 10 on the cabinet door 31, a fixing ring 13 is sleeved at the end of the cover 12.

[0050] The fixing ring 13 is made of silicone or rubber as a whole. That is, after the alarm module 10 passes through the cabinet door 31, the alarm module 10 is fixed by sleeving the fixing ring 13. A round hole 311 for the alarm module 10 to pass through is provided on the cabinet door 31, and a guiding groove 312 for cooperating with the guiding block 122 is provided at the top of the round hole 311. An interference fit exists between the fixing ring 13 and the cover 12, and one end of the fixing ring 13 connected to the cover 12 is a deformation area 132, whose diameter is slightly smaller than that of the cover 12. After the fixing ring 13 is sleeved on the cover 12, the pressure on the cover 12 increases, so that the frictional force between the two is greater, further enhancing the connection effect.

[0051] As Figures 6-7 shown, on the basis of Embodiment 1, a groove 121 for cooperating with the connection of the fixing ring 13 is provided on the cover 12 of the alarm module 10 in this embodiment. That is, the fixing ring 13 is fixed and limited through the groove 121 to prevent the alarm module 10 from falling due to impact, further increasing its fixing effect. A wedge-shaped groove 131 is also provided near one side of the cover 12, and a strong magnetic ring 14 is embedded in it. Since the cabinet door 31 is generally made of iron or an iron-containing alloy, the fixing ring 13 with a magnetic ring structure can increase the connection strength and stability between the alarm module 10 and the cabinet door 31.
