Sensing network system for monitoring vehicle-mounted hazardous article and monitoring method

Abstract

The invention relates to a vehicle mounted dangerous articles control sensor network system, including: a dangerous articles detection sensor, installed around dangerous articles; a video acquisition device, installed above the dangerous articles, for acquiring and outputting video signals; a display screen, connected with the video acquisition device, for receiving video signals output from the video acquisition device; a wire transmission module, connected with the video acquisition device and the display screen, for transmitting the video signals from the video acquisition device onto the display screen; a signal processing module, for receiving analog induction signals and outputting digital sensing signals; a wireless transmission module, connected with the signal processing module, for transmitting outside in a wireless mode; a central control module, for receiving the digital sensing signals and determining to output control signals when the digital sensing signals represent the occurrence of dangerous articles and heterogeneous; a short message alarm module, connected to the central control module, transmitting alarming short messages to mobile phone of appointed users in a short message mode; a audible alarm module, connected to the central control module, for receiving the control signals transmitted from the central control module through a CDMA wireless network; a GPS locating module, installed on vehicles transporting dangerous articles, for reporting the accuracy position of vehicles toward control center in real time. The invention also provides a monitoring method, which effectively reduces work intensity of staff, improves reliability of vehicle mounted dangerous articles carriage, and can reduce false dismissal rate and false alarm rate.

Description

technical field [0001] The present invention relates to a vehicle-mounted dangerous goods monitoring sensor network system, in particular to a vehicle-mounted dangerous goods monitoring sensor network system that monitors the whole process of the transportation process of dangerous goods, and the system can monitor the state of the vehicle-mounted dangerous goods throughout the process , Once any abnormal situation such as position movement, physical and chemical property change, liquid leakage, gas leakage, etc. is detected, the system will carry out remote control at any time. Background technique [0002] In our country, with the improvement of people's awareness of safety precautions, the application fields of security products are becoming more and more extensive. At the same time, the wide application of digital technology and the internationalization of the market have led to the development trend of digitalization, automation and networking in security products.
