Real-time weight monitoring method and system of compartment type hazardous chemical substance transport vehicle

The present invention discloses a real-time weight monitoring method and system of a compartment type hazardous chemical substance transport vehicle. The system comprises a vehicle-mounted weight measurement device, a vehicle-mounted terminal, a receiver, a transmitter and an alarm system, wherein the vehicle-mounted weight measurement device measures the weight of a hazardous chemical substance in real time and transmits data to the transmitting device; the transmitting device is used for receiving the data of the weight measurement device and wirelessly transmuting the data; the receiver is connected with the vehicle-mounted terminal and is used for receiving the data from the transmitting device and transmitting the data to the vehicle-mounted terminal; the vehicle-mounted terminal is provided with a memory and a processor; and when the received data are largely different from upper and lower limit values set before transportation, the vehicle-mounted terminal outputs abnormal signals to the alarm system,
