Transporting dangerous goods is a very high-risk industry, so if you reduce the risk?
Dangerous goods transport GPS vehicle management system can monitor the position, speed, direction, environment, etc. of the transport vehicle in real time, so that the control center can make correct measures to avoid huge losses and serious threats to the local ecosystem and personal safety. The following is a brief introduction to the dangerous goods transport GPS vehicle management system.
First, the overall design of the system
Overall, the GPS vehicle management system for dangerous goods vehicles consists of three parts: the vehicle GPS terminal, the space satellite transmission system and the customer service center. The vehicle GPS terminal is mainly composed of various sensors and information collection systems. It is responsible for transmitting the real-time data such as the position of the vehicle, the speed of the vehicle, the driving environment and the temperature inside and outside the vehicle to the control center through the satellite transmission system, and then the customer service center for the entire dangerous goods vehicle. The hardware and software of the GPS vehicle management system are coordinated and processed to centrally realize services such as monitoring, scheduling, pick-up/warning, and image processing.
Second, the construction of software and hardware systems
The car client selects the SiRF Starlll third-generation chip, which uses a four-core processor and runs the memory above IG. At the same time, the hard disk drive where the operating system requires is more than 10G. The server side selects a CPU with a running frequency of 2.3 GHz or higher, and the running memory is above 4G, and at the same time requires at least 100G of the drive where the operating system is located. The software system is based on the proprietary operating system developed by Microsoft system WINDOWS, and the database engine uses MSSQL Server2008.

Third, functional design
1. Vehicle tracking and monitoring
The GPS vehicle management system establishes a fast, accurate and effective information transmission channel between the vehicle and the monitoring center. The customer service center can control the basic vehicle status such as the position, speed and form direction of the dangerous goods transport vehicle at any time, and quickly dispatch the dispatch. The instructions can also provide the necessary service information for the vehicle.
2, speed / parking alarm
In the specified sections and road conditions, the dangerous goods transport vehicle needs to maintain a certain speed and ensure the smoothness of the vehicle. The customer service center can collect the current situation of the driving section in advance, and then preset the driving speed for each section. When the actual driving speed exceeds or falls below the set threshold, the alarm system automatically sends a warning message to remind the driver to remain within the specified speed range, or to ask the driver to report the specific situation.
3, emergency alarm
Dangerous goods transportation is actually a special transportation task. It is inevitable that some unexpected situations will occur. When the vehicle encounters an emergency, the driver only needs to press the emergency alarm. The GPS vehicle terminal will automatically issue an alarm command to the customer service center. Corresponding automatic data collection, the location of the vehicle will be automatically displayed on the monitoring platform of the customer service center, and the sound and light will be prompted. At the same time, when a vehicle encounters a car accident, road condition damage, vehicle failure, etc., it can report to the service center in time through the alarm system, waiting for the processing of the command center, and must not increase the accident risk because of blind treatment.

4, remote control
When the dangerous goods transport vehicle fails or is in a traffic accident and the driver cannot control it, the customer service center can send a fuel cut/electric command to the GPS vehicle terminal equipped with the control device when the fault is confirmed, and then the control system will automatically perform When the oil is cut off or the power is cut off, the vehicle will not ignite, and the probability of secondary accidents caused by vehicle oil leakage or electric spark is greatly reduced, which improves the overall safety factor level of the vehicle.
The dangerous goods transportation vehicle management system developed based on GPS communication technology realizes all-weather, multi-faceted and full-section monitoring of transportation vehicles, effectively reducing the probability of occurrence of safety accidents and improving the safety factor during the transportation of dangerous goods. In the near future, this system can achieve leapfrog development based on the reform and innovation of information technology and GPS communication technology.
