2 Ways to Monitoring Machine OEE Rate

In industrial production, equipment is often in different states, such as maintenance, shutdown, etc., which makes it difficult to evaluate production efficiency, the return on investment of machinery and equipment, and the vacancy rate, which brings cost assessment to many manufacturing companies. certain difficulties. Therefore, it is very important to collect the equipment utilization rate OEE of the factory floor.

The equipment on the factory floor is difficult to wire and there are many types of equipment. Therefore, specific solutions need to be adopted according to different situations.

1. The factory workshop equipment is not suitable for wiring

In this case, because the device is not convenient for wiring, it needs to use wireless transmission. There are two types of wireless transmission, one is WIFI and the other is Lora. Because WIFI is affected by the stability of the WIFI router, Lora wireless technology is generally used. . As shown below:

Through the WT101 wireless Lora andon status acquisition module, the signal of the device andon is collected, and the status of the device is judged according to the signal. Then the WT101 wireless Andon acquisition module transmits the data wirelessly to the Lora gateway S281 through Lora, and the S281 wireless Lora gateway transmits the data to the host computer or cloud platform through the Ethernet or 4G network according to the Modbus TCP or MQTT protocol. In this way, the collection of OEE of equipment utilization rate in the factory workshop is realized.

The characteristics of this scheme are: low cost, simple and easy to use.

2. The situation of factory workshop equipment can be wired

In this case, the device status can be collected through the M210T Ethernet remote IO module or the M210E dual-port cascadable Ethernet I/O module, because the Ethernet IO module supports the MQTT protocol, the Modbus TCP protocol, and the Modbus RTU protocol, so it can be directly transmitted to the remote industrial Internet of Things platform, and can also be transmitted to the local host computer system, thus realizing the collection of equipment utilization rate.

Through the above two methods, OEE data collection of the utilization rate of machinery and equipment in the factory workshop can be easily realized, thereby improving the utilization rate of equipment and equipment.
