The invention provides a whole-process real-time electronic scale type intelligent supervision management system for an oil tank truck. The system comprises a vehicle-mounted terminal and a monitoringplatform; the vehicle-mounted terminal is connected with the monitoring platform through a wireless data network; the vehicle-mounted terminal is connected with a monitoring unit on the oil tank truck through a data line; the monitoring unit monitors the liquid level, the pressure, valve switching, the position, the surrounding environment and other data of the oil tank truck; and the monitoringplatform comprises a streaming media service layer, a protocol analysis layer, a data processing layer and a platform service layer, and can be connected with multiple kinds of clients through application interfaces (API) to form an application service layer for interaction between the clients and the monitoring platform, so that interconnection, intercommunication, mutual control and other various applications can be realized. According to the system, remote real-time monitoring and analysis of the liquid level, the pressure, the leakage, the position, the valve switching, a vehicle track, the surrounding environment and other states of the oil tank truck can be realized, thereby providing information support for dispatching delivery, equipment management and decision-making operation inthe hazardous chemical industry.
