Two common OEE monitoring methods for equipment utilization

How to improve the utilization of equipment is a common problem in the manufacturing industry , On the technical , Generally, monitoring equipment is used to monitor the movement rate OEE To calculate , So as to improve the utilization rate of equipment 、 Reduce the idle rate of equipment to improve business efficiency . But the equipment environment of factory workshop is complex , There are wiring difficulties 、 There are many types of equipment , therefore , Specific solutions need to be adopted according to different situations .

One 、 The factory workshop equipment is not suitable for wiring

under these circumstances , Because the equipment is not convenient for wiring , Therefore, wireless transmission is required , Wireless transmission has 2 Kind of , One is WIFI, One is Lora, because WIFI suffer WIFI The impact of router stability , So we usually use Lora Wireless technology . As shown in the figure below ：

adopt WT101 wireless Lora Safety lamp status acquisition module , Collect the signal of equipment lighting , Judge the status of the equipment according to the signal . then WT101 The wireless lighting acquisition module passes the data through Lora Wireless transmission to Lora gateway S281 On ,S281 wireless Lora The gateway passes through Ethernet or 4G The network follows Modbus TCP or MQTT The protocol is transmitted to the upper computer or cloud platform . Thus, the equipment utilization rate of the factory workshop is realized OEE Collection .

Two 、 The situation that the equipment in the factory workshop can be wired

        In this case , Can pass M210T Ethernet Remote IO Modules, or M210E Dual port cascadable Ethernet I/O The module collects equipment status , Because Ethernet IO Module support MQTT Deal with the Modbus TCP agreement , And support Modbus RTU agreement , Therefore, it can be directly transmitted to the remote industrial Internet of things platform , It can also be transmitted to the local host computer system , Thus, the acquisition of equipment movement rate is realized .

 

Through the above two methods , It can easily realize the utilization rate of mechanical equipment in the factory workshop OEE Data collection , So as to improve the utilization of equipment .
