Data acquisition system gateway acquisition plant efficiency

In industrial production , Devices are often in different states , Like maintenance 、 Shutdown and other states , It is difficult to evaluate the production efficiency and the return on investment of machinery and equipment 、 Use vacancy rate, etc , It brings certain difficulties to the cost evaluation of many manufacturing enterprises . therefore , Collect the equipment utilization rate of the factory workshop OEE It's very important .
There is difficulty in wiring factory workshop equipment 、 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 .

 

The characteristics of this scheme are ： The cost is low 、 Simple and easy to use .

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 .
