Industrial Automation
Background
The technical performance of concrete mixing equipment of batch plants can directly affect the quality and service life of the construction projects. Concrete batch plants need to perform routine maintenance to timely detect, maintain and repair any defective parts of the mixing equipment, to reduce damage and prevent equipment from being unable to perform normal production operations. The fault elimination and maintenance of concrete mixing equipment were traditionally done by local service departments of the manufacturer, or by manufacturer employees sent to the site. This will not only bring after-sales service costs high, but will also affect the production progress of the batch plants.
Intelligentization is the ultimate development direction of mechanical equipment, the concrete mixing equipment is no exception. InHand introduces a remote maintenance system for concrete mixing equipment based on PLC and wireless communication technology, using InHand 4G industrial router IR915. The maintenance staff can perform remote diagnosis, early warning and maintenance of the mixing equipment in real time while away from the production site.
InHand Reomte Monitoring Solution
The monitoring system of concrete mixing equipment consists PLC, edge computing gateway InRouter915 and cloud monitoring center.
● The InHand edge computing gateway InRouter915 connects one or more field PLCs to form a field network of concrete mixing equipment, collect data of field controllers and sensors, and upload the data intelligently with local caching mechanism.
● The edge computing gateway runs a data acquisition APP within and transmit the APP data to the cloud monitoring center through MQTT protocols. In this way, data reliability, real-time and security are ensured, and data flow costs is saved.
● The field data is uploaded to the cloud monitoring center, maintenance staff can remotely diagnose, pre-alert and maintain the mixing equipment in real time away from the production site, and can monitor a large number of concrete mixing stations.
