Description

Electronic kanban system for production management and display method thereof

The present invention relates to the field of industrial production management systems, and more particularly to an electronic signage system for production management and a display method thereof. Background technique'

As China joins the WTO, the competition between enterprises is becoming more and more fierce. Strengthening production management and improving production efficiency are the key to improving the competitiveness of the market. In the production process of enterprises, the traditional management method is to set up a group of grassroots managers such as the squad leader and team leader. Through these squad leaders and team leaders, we directly supervise and manage the grassroots employees at each station.

At present, some electronic kanban systems for enterprise production management have begun to appear in the market, but these traditional electronic kanban systems still have some shortcomings:

1. The production equipment is separate from the kanban system. It is necessary to manually send information related to the current working state of the production equipment to the control center of the kanban system.

2, using the traditional electronic signage system, if you need to know some data of the current working state of the production equipment, you need to use a special measuring instrument, for example, you need to measure the speed of the processing wire, you need to use the speed sensor to measure the speed of the wire when discharging, If you need to measure the speed of processing tablets, you need to use infrared detectors to control the number of drugs discharged from the mouth. However, in this case, different instruments require different measuring instruments. When the same device requires different data, multiple measuring instruments are required. Therefore, the traditional electronic signage system is very complicated to build and the cost is very high. Summary of the invention

For example, the temperature in the oven will be different. The temperature change in the oven can be measured by the thermocouple. When the temperature in the oven is 150 degrees, the micro voltage generated by the thermocouple is 0, 2m is converted by the conversion module. The DC or AC voltage finally collected by the device 200 is 6V. When the temperature in the oven is 200 degrees, the micro voltage generated by the thermocouple is 0,3Γη\ζ, after the conversion module is converted, the DC device finally collected by the collecting device 200 or The AC voltage is 9V. When the temperature in the oven is 300 degrees, the micro voltage generated by the thermocouple is 0, 4mV. After the conversion module is converted, the DC or AC voltage finally collected by the acquisition device 200 is 12V.

For example, the refrigeration equipment is required to maintain power supply, and the DC or AC voltage of the air compressor of the refrigeration equipment can be non-zero when the normal operation is set on the production equipment state calculation unit 302. If the faulty device is not working, the DC or AC voltage of the air compressor is zero. When the collecting device 200 collects the DC or AC voltage of the air compressor of the refrigeration device is zero, the production equipment state calculating unit 302 Refrigeration equipment failure can be obtained by calculation.
