Machinery monitoring device based on 4G network cloud server

The invention provides a machinery monitoring device based on a 4G network cloud server, which comprises engineering machinery and a cloud server. A 4G communication module is arranged on the engineering machinery and the cloud server; the engineering machinery and the cloud server are in communication connection through the 4G communication module; a GPS module is arranged on the engineering machinery, so that longitude, latitude and speed information of a vehicle to be monitored can be obtained in real time through the GPS module on the map; high precision positioning information of the engineering vehicle at any location and in any time can be obtained; the corresponding association between online and offline states of data transmission network is completed; and an ultrasonic sensor isarranged on an oil tank of the engineering machinery. According to the machinery monitoring device based on the 4G network cloud server, remote real-time monitoring is completed utilizing a computer,and the machinery in the f
