Detailed ways

Make the present invention with reference to accompanying drawing 1, Fig. 2. The relay protection plug-in intelligent storage cabinet includes a cabinet body 1, a cabinet door 2, a touch-sensitive LCD screen 5 and a main control unit 6. A touch-sensitive LCD screen 5 and a main control unit 6 are provided, and the main control unit 6 is connected with the touch-sensitive LCD screen 5 through a data line, and the data is input to the processor on the main control unit 6 through the touch-sensitive LCD screen 5, and the main control unit The data processed by the processor on the control unit 6 is output to the touch-sensitive LCD screen 5 for display. It is characterized in that: a vertical support plate 12 is fixed in the cavity of the cabinet body 1, and a plug-in is arranged on the vertical support plate 12. The placement device is provided with a heating device at the bottom of the cavity of the cabinet body 1, and a limit switch 8 is provided on the plug-in placement device. The limit switch 8 is connected to the main control unit 6 through a wire. When it is inside, it touches the limit switch 8, and the limit switch 8 transmits the signal to the main control unit 6. After the signal is processed by the main control unit 6, it is transmitted to the touch-sensitive LCD screen 5 for display. In this way, the touch-sensitive LCD screen 5 can display the location and model of the relay protection plug-in storage, which is convenient for management and use.

The plug-in placement device includes an upper clamping plate 7, a lower clamping plate 11, a clamping groove 9 and a positioning bolt 10, the vertical support plate 12 is provided with a vertical chute, and the two ends of the upper clamping plate 7 are respectively Be fixed in the chute of two vertical support plates 12 by positioning bolt 10, the two ends of lower clamping plate 11 are respectively fixed in the chute of two vertical support plates 12 by positioning bolt 10, upper clamping plate 7 and lower clamping plate 11 are parallel to each other, and the bottom panel of the upper cardboard 7 and the top panel of the lower cardboard 11 are provided with mutually symmetrical card slots 9, and the relay protection inserts are inserted in the mutually symmetrical upper and lower card slots 9.

The limit switch 8 is fixed on the inner end of the card slot 9 of the lower card plate 11, and the limit switch 8 can be contacted after the relay protection plug-in is inserted, so that the corresponding card slot can be displayed on the touch-sensitive LCD screen 5 9 for the model number of the plug-in.

The heating device includes a heater 13, a temperature and humidity sensor 14, a temperature and humidity display screen 3 and a switch 4, the temperature and humidity sensor 14 and the heater 13 are fixed at the bottom of the cabinet 1 cavity, and the temperature and humidity display screen 3 and the switch 4 are located on the cabinet door 2, the heater 13 and the switch 4 are connected by wires, the temperature and humidity sensor 14 is connected to the temperature and humidity display screen 3 by data lines, when the temperature and humidity in the cabinet body 1 are on the temperature and humidity display screen 3 When the display fails to meet the standard, the system will automatically turn on the heater 13 for heating and dehumidification; if the automatic control fails or manual intervention is required in the environment, the heater 13 can be turned on or off manually through the switch 4 .

There are multiple plug-in placement devices, so that the upper clamping plate 7 and the lower clamping plate 11 are also provided with multiple sets, so as to place a plurality of different types of relay protection plug-ins; There are multiple groups.

The main control unit 6 is connected with the barcode scanner through a data line.

The present invention is used indoors, and all metal parts should be well grounded. When the temperature in the cabinet 1 is lower than the lower limit (set to 15° C.) or the humidity is higher than the upper limit (set to 40%), the heater 13 is started to ensure a good storage environment. The plug-in statistical management module (namely the main control unit 6) is realized through an ARM-based embedded system. The collection and positioning of the plug-in information is realized through barcode scanning and the limit switch 8 on the card slot 9 , and the human-computer interaction operation is performed through the touch-sensitive LCD screen 5 . When the cabinet door is opened, the management system enters the working state, and the barcode scanning device is opened. After the scanning is completed, the plug-in is inserted into the empty card slot 9 . If the scanning fails or there is no barcode label, you can manually select the corresponding model in the menu. After inserting in place, the system will prompt that the operation is successful and the storage is complete. The touch LCD screen 5 provides browse and search functions, and can check the storage space situation and the reserved quantity and position of various plug-ins at any time. When taking it, directly open the cabinet door 2 to take it out. After the system detects that the plug-in is pulled out, it will prompt to select the purpose (factory station name). After the selection is completed, the system will prompt that the operation is completed. The database of plug-in model/barcode and plant name is preset and maintained by computer, without on-site input. The access records can be output immediately through the built-in small printer, and the complete list can also be exported to the computer. The system uses the USB interface to communicate with the computer, and can directly operate files on the computer side. The whole system is easy to learn and easy to use.
