Description

Technical Field

[0001] The invention relates to the field of electric power equipment, in particular to a machine room warning device. Background Art

[0002] When the power distribution cabinet in the computer room is undergoing maintenance and overhaul, the power must be turned off before the cabinet can be opened for operation. In addition, in order to remind the operator, warning signs need to be placed on the front and rear doors of the working cabinet, such as hanging a "Work Here" sign and a "Running Equipment" red curtain on the adjacent cabinet.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1, reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a machine room warning device, which can ensure that the cabinet 101 will display a safety signal only when it is safely unlocked, and will display a warning signal when the cabinet 101 is unsafe and cannot be operated, and includes:

[0027] The installation component 100 includes a cabinet 101 and a control unit 102 disposed on the top of the cabinet 101. The control unit 102 is provided with a signal transmission device, a signal receiving device and a processing chip, so that the warning device of the cabinet 101 can be operated by remote control. Preferably, the control unit 102 can be associated with the work ticket module of the master station OMS. By clicking on the door of the cabinet 101 at the work location on the APP or the master station OMS system, the light warning change and automatic locking can be realized, thereby reducing the risk of staff accidentally operating the non-working cabinet 101 and reducing maintenance costs; and,

[0028] The warning component 200 includes a door lock 201, a sensor structure 202 arranged inside the door lock 201, and a warning light structure 205 arranged above the door lock 201. The locking rod structure of the door lock 201 is installed on the door of the cabinet 101, and the lock box matched with the locking rod is installed on the door frame. The warning light structure 205 will display a specific color light to indicate whether the cabinet 101 is safe, which serves as a warning. The door lock 201 can be remotely controlled and automatically unlocked or locked, and the warning light structure 205 is associated with the door lock 201. When the door lock 201 is completely locked, the warning light will display the relevant color light.

[0029] Specifically, the control unit 102 can be associated with the main station OMS work ticket module. The staff can click on the door of the cabinet 101 at the workplace on the handheld computer to change the light warning and automatically lock it, which can reduce the risk of the staff accidentally operating the non-working cabinet 101.

[0030] Example 2, reference Figures 1 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a specific warning process of the warning light structure 205 of the computer room warning device. The side of the cabinet 101 is provided with a cabinet door 103, and the door lock 201 is provided on the outside of the cabinet door 103. The side of the door lock 201 is provided with an unlocking structure 203, and the unlocking structure 203 can automatically unlock and lock. The top of the unlocking structure 203 is provided with an external interface 204, and the external interface 204 provides an interface for controlling the unlocking structure 203 from the outside.

[0031] Furthermore, the warning light structure 205 includes a light strip 205f arranged on the side of the cabinet door 103, and the unlocking structure 203 includes an electric telescopic rod 203a arranged on the side of the door lock 201, and the movable end of the electric telescopic rod 203a is connected to the locking rod of the door lock 201, and the electric telescopic rod 203a is used to control the extension and retraction of the locking rod, thereby realizing automatic unlocking and locking.

[0032] Furthermore, the unlocking structure 203 further includes a filter capacitor 203c, a protection resistor 203d and an electric socket 203b, wherein the filter capacitor 203c is electrically connected to the electric telescopic rod 203a, the electric socket 203b is electrically connected to the electric telescopic rod 203a, the filter capacitor 203c is connected in parallel to the electric socket 203b, the protection resistor 203d is electrically connected to the electric telescopic rod 203a, and the electric socket 203b is connected to the external interface 20 4 is electrically connected, the power socket 203b is connected to the power supply to power the electric telescopic rod 203a, and the filter capacitor 203c can filter out high-frequency noise in the circuit to protect the circuit. However, since the unlocking structure 203 is arranged on the powered cabinet 101 in the power station, it is prone to failure. When a failure occurs, it will lead to failure to unlock. At this time, it is necessary to use the external interface 204 to connect the external power supply, and drive the electric telescopic rod 203a to unlock through the power socket 203b, so as to ensure that the unlocking can be achieved even if the circuit fails.

[0033] Furthermore, the warning light structure 205 also includes a control chip 205a, a red light 205b, a green light 205c, a first resistor 205d, and a second resistor 205e. The red light 205b and the green light 205c are both arranged inside the light bar 205f. The control chip 205a is electrically connected to the red light 205b, the control chip 205a is electrically connected to the green light 205c, the red light 205b is connected in parallel to the green light 205c, and the first The resistor 205d is connected in series with the red light 205b, and the second resistor 205e is connected in series with the green light 205c. The algorithm is written in advance in the control chip 205a. Through remote control and monitoring, when the power inside the cabinet 101 is cut off and it is safe to operate, the door lock 201 can be opened, and the warning light will show the green light 205c, indicating that the cabinet door 103 can be opened for maintenance. When the power inside the cabinet 101 is not cut off, the door lock 201 is in a locked state, and the warning light shows the red light 205b, indicating that the cabinet door 103 cannot be opened.

[0034] Specifically, the operator remotely monitors the internal situation of the cabinet 101. When the power inside the cabinet 101 is cut off and it is safe to operate, the door lock 201 can be opened and the warning light will show a green light 205c. When the power inside the cabinet 101 is not cut off and the door lock 201 is in a locked state, the warning light will show a red light 205b, which can prevent the risk of electric shock caused by the staff's misoperation. At the same time, if the control circuit fails and cannot be unlocked normally, the external interface 204 can be used to connect an external power supply to drive the electric telescopic rod 203a to unlock through the power socket 203b.

[0035] Example 3, reference Figures 1 to 5, which is the third embodiment of the present invention. Different from the previous embodiment, the sensor structure 202 includes an infrared generator 202a arranged on the inner wall of the door lock 201, and an infrared receiver 202b is arranged above the infrared generator 202a. The infrared receiver 202b is arranged on the inner wall of the door lock 201. The sensor structure 202 also includes a sensor chip 202c, and the sensor chip 202c is electrically connected to the red light 205b. When the door lock 201 is in the unlocked state, the lock rod is driven to retract by the electric telescopic rod 203a, and is separated from the matching When the cabinet door 103 is in the closed lock frame, the infrared ray emitted by the infrared generator 202a will be received by the infrared receiver 202b, so the signal of the infrared receiver 202b is transmitted to the control chip 205a, and the control chip 205a controls the green light 205c to light up, indicating that the cabinet door 103 can be opened safely. When the locking rod is extended into the lock frame, the infrared ray generated by the infrared generator 202a is blocked by the locking rod and cannot be transmitted to the infrared receiver 202b, so the signal is transmitted to the control chip 205a, and the control chip 205a controls the red light 205b to light up, indicating that the cabinet door 103 is locked and there is a risk in opening the door.

[0036] Specifically, the sensor can detect whether the door lock 201 is locked, and transmit different signals to the control chip 205a in the warning light structure 205, controlling the red light 205b or the green light 205c in the warning light structure 205 to light up, providing a warning signal to the staff to prevent the staff from causing safety risks due to misoperation.
