Problems solved by technology

[0003] The above-mentioned low-voltage power distribution system can solve the problems of power supply, control and maintenance in the production of enterprises. However, if the enterprise is large in scale, has multiple production workshops, has many production equipment, is more complicated, and the location is relatively scattered, each low-voltage power distribution The cabinet 13 needs to receive a variety of operating status information of the production equipment 14 in real time and send it to the main controller 11, which affects the data processing capabilities of each voltage distribution cabinet 13 and the main controller 11, as well as the There are high requirements for data communication capabilities between enterprises, which will lead to the cost of installing and operating low-voltage power distribution systems for enterprises
[0004] Most of the operating status information of production equipment is a low-range voltage signal. For example, a 1V-5V analog signal is used to represent the temperature range of 0-100 degrees, and a 1V or 5V signal is used to represent the switching signal of the equipment. The low-voltage signal is in the In long-distance transmission, due to problems such as high-voltage signal interference, large deviations may occur, resulting in a large gap between the operating status of the production equipment displayed on the display 12 and the actual operating status of the production equipment, directly affecting the production efficiency and production safety of the enterprise.
[0005] Applying the above-mentioned low-voltage power distribution system, when the production equipment or the low-voltage power distribution cabinet 13 breaks down, maintenance personnel need to rush to the main control room to check the cause of the failure, and then bring relevant maintenance data to the failed production equipment or low-voltage power distribution cabinet Maintenance at 13 places affects the response speed of equipment maintenance, increases the burden on maintenance personnel, and reduces the efficiency of equipment maintenance

Embodiment Construction

[0024] In the present invention, a display screen is set on the low-voltage power distribution cabinet to display the operation state information of the production equipment connected to the low-voltage power distribution cabinet. The requirements of the data processing capacity of the electric cabinet, and avoid the error display of the operating status information due to interference and distortion during the transmission process, and improve the accuracy of displaying the operating status of the production equipment.

[0025] The invention stores maintenance data in the low-voltage power distribution cabinet. When the low-voltage power distribution cabinet or the production equipment connected to the low-voltage power distribution cabinet fails, the maintenance personnel can directly retrieve the maintenance data from the low-voltage power distribution cabinet. According to the maintenance data Maintain the low-voltage power distribution cabinet and its connected production ...
