[0075] In some embodiments, the control modules 14 of several electrical cabinets are communicatively connected; when any electrical cabinet is in an abnormal state due to fire or action of a protective device, the remaining electrical cabinets instruct the electrical cabinet in the abnormal state.

[0076] Some other embodiments of the present invention provide a control method for an intelligent panel eyebrow system of an electrical cabinet, which is used to control the intelligent panel eyebrow system as described in any of the above embodiments, and the control method includes:

[0077] Acquire electrical cabinet status information of the current electrical cabinet, wherein the electrical cabinet status information at least includes environmental fire information, electrical cabinet power-on status information, electrical cabinet door opening and closing status information, and protection device action status information;

[0078] Determine the current operating state of the electrical cabinet according to the electrical cabinet state information, wherein the current operating state of the electrical cabinet includes a first state, a second state, a third state and a fourth state;

[0079] According to the current operating status of the electrical cabinet, the corresponding sound and light broadcast of the operating status is carried out.

[0080] Specifically, the first operating state is used to indicate that the electrical cabinet is not powered on, no fire has occurred, and the protection device is not activated; the second operating state is used to indicate that the electrical cabinet is powered on, no fire has occurred, and the protection device is not activated; the third operating state is used to indicate that the electrical cabinet is powered on, no fire has occurred, and the protection device has been activated; the fourth operating state is used to indicate that a fire has occurred in the electrical cabinet;

[0081] Among them, in the second operating state, the third operating state and the fourth operating state, only when the door of the electrical cabinet is in the closed state, the voice broadcast is performed according to the current operating state of the electrical cabinet.

[0082] In some embodiments, when the electrical cabinet is in the third operating state or the fourth operating state, the intelligent panel systems of other electrical cabinets will receive and display alarm information to provide maintenance personnel with on-site working condition information. In a specific embodiment, each control module is interconnected through an RS-485 bus to define a master-slave communication protocol; the master cabinet periodically polls the status of each slave cabinet, and the slave cabinet actively reports abnormal events; when any electrical cabinet triggers the third or fourth state, the master cabinet receives the alarm code, and the LED screens of all interconnected cabinets synchronously display the abnormal cabinet number and status color, and the master cabinet voice module broadcasts a global alarm to achieve the purpose of quickly locating the fault.

[0083] In a specific embodiment, the specific execution logic of the control method is as follows:

[0084] Get the power-on status information of the electrical cabinet S power , electrical cabinet door opening and closing status information S m , Environmental fire information S f , protection device action status information S d , infrared probe status information S hw The above information can use "0" and "1" to represent opposite states. For example, the protection device action state information S d When it is 0, it means that the protection device is not in action, and the protection device action status information S d When it is 1, it indicates that the protection device has been activated.

[0085] When the electrical cabinet is not powered on, no fire occurs, and the protection device is not activated, the electrical cabinet is determined to be in the first operating state, and the background color of the LED display screen is green;

[0086] When the electrical cabinet is powered on, no fire has occurred and the protection device has not been activated, the electrical cabinet is judged to be in the second operating state. If the electrical cabinet door is not opened and the infrared probe detects a person approaching, the voice broadcast "This cabinet is powered on, please open the door"; and the background color of the LED display screen is displayed in white;

[0087] When the electrical cabinet is powered on, no fire has occurred and the protection device has been activated, the electrical cabinet is judged to be in the third operating state. If the electrical cabinet door is not open, the voice broadcast "xx cabinet device tripped"; and the background color of the LED display screen flashes red and green alternately;

[0088] In any case, when a fire occurs in the electrical cabinet, the electrical cabinet is determined to be in the fourth operating state. If the electrical cabinet door is not opened, a voice announcement is made "A fire has occurred in this area, please evacuate as soon as possible"; and the background color of the LED display screen is displayed in red.

[0089] It should be noted that, in the second operating state, the third operating state and the fourth operating state, voice broadcast is performed according to the current operating state of the electrical cabinet only when the cabinet door is closed, because this is to avoid false alarms caused by maintenance operations.

[0090] In addition, under normal circumstances, when the staff opens the electrical cabinet, the name of the current electrical cabinet and whether the cabinet is powered on will be announced by voice.

[0091] In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0092] Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
