1. System Overview
In the process of improving the logistics safety management system of hazardous chemicals, Tianyizhonghe designed a set of risks based on radio frequency technology (RFID), global satellite positioning system (GPS) and wireless communication system GPRS/CDMA technology for transportation problems. The chemical transportation monitoring and management system realizes the full traceability of hazardous chemical information, the full monitoring of transportation vehicles, the unified integration of production, transportation, and storage system information, and the system’s automatic real-time alarm and other functions. On this basis, the extended application of the installation of temperature, humidity, pressure, vibration and other sensors is proposed to ensure the safe transportation of hazardous chemicals.
2. System composition
The system consists of passive RFID radio frequency tags, portable PDAs, fixed readers, electronic locks and monitoring centers. The monitoring center uses the monitoring management system to monitor hazardous chemicals in real time.
Companies producing, transporting, and warehousing hazardous chemicals have their own independent management systems. The monitoring and management system develops an information query system based on the data interfaces provided by the production management system, transportation management system and warehouse management system, and calls in real time to view information about hazardous chemicals in the independent systems of production plants, transportation and storage.
Through the global positioning system GPS module and wireless communication GPRS/CDMA module installed on the transport vehicle, the driving route of the transport fleet is displayed on the interface of the real-time information management system. The status information of the portable PDA and the fixed reader to read and write hazardous chemicals and the alarm information of the electronic lock will be uploaded to the real-time information management system in real time, so as to achieve the purpose of monitoring and management.
3. Implementation process
Production
Manufacturers paste passive electronic tags on single pieces or packages of hazardous chemicals, and use portable PDAs or fixed readers to enter the information of hazardous chemicals into passive electronic tags, including name, model, quantity, weight, All information related to pressure, temperature, manufacturer, etc.
transportation
Before transporting hazardous chemicals onto the vehicle, transport personnel use portable PDAs to read and write hazardous chemicals affixed with passive electronic tags, including the vehicle number, vehicle model, maximum load capacity of the vehicle, and driver’s name on the vehicle where the hazardous chemical is loaded , Company and other information. This information can be transmitted to the monitoring and management system through the communication function of the PDA.
Use an electronic lock system to replace the traditional lead seals for electronic monitoring and management of cargo containers. The electronic lock has low power consumption, is simple, practical, easy to operate, reusable, economical, and has the dual functions of mechanical locking and electronic sealing. When there is a need to unload on the way, the vehicle-mounted personnel use the handheld PDA to input the password of the electronic lock, and the electronic lock is unlocked to load and unload the goods. This action will be monitored in real time by the monitoring center. For vehicles that do not need to be unloaded midway, the consignee can only enter the password when arriving at the destination to unlock the electronic lock. If the electronic lock is illegally disassembled in the middle, it will report to the monitoring center immediately.
The transportation vehicles are equipped with GPS and GPRS/CDMA systems, and the driving route will be displayed in real time on the electronic map of the monitoring system.
Warehousing
When the hazardous chemicals arrive at the destination, unlock the electronic lock. Receiving personnel use portable PDA/fixed readers to read and write information, including: receiving company, consignee, quantity of goods, whether there are any abnormal problems, etc. After the management system of the monitoring center receives the information and confirms the safe receipt, the transportation monitoring process is completed.
4. System function
Full traceability of hazardous chemical information
In the entire process from production, transportation to storage, the information is transmitted to the monitoring center in real time through the reading and writing of portable PDA or fixed reader at every link of the dangerous chemicals.
Full monitoring of transportation vehicles
The driving position and route of the transportation vehicles are displayed and updated in real time on the electronic map of the monitoring center, which is convenient for management personnel to dispatch the vehicles in real time.
Unified integration of production, transportation, and warehousing system information
The information query system can use the access rights of the monitoring center to query the transportation of hazardous chemicals information on the independent management systems of the production, transportation, and storage companies. Its data information can be correspondingly integrated to provide data analysis for planning and decision-making and data comparison with real-time information management systems for monitoring management.
Real-time alarm
When the electronic lock is opened or damaged in violation of regulations, the monitoring center will immediately receive an alarm message.
The driving route of the chemical dangerous goods transportation vehicle can be specified in advance. If the route is shifted, the monitoring and management system will automatically alarm.
When the monitoring system displays the driving route of the transportation vehicle, it will obtain the data of the driving speed of the vehicle. Once the speeding is detected, the system will automatically alarm.
When transport personnel use portable PDA to enter information about the hazardous chemicals that will be loaded into the vehicle, the monitoring center will obtain the weight of the loaded single or package of hazardous chemicals and the maximum load capacity of the transport vehicle, and the system will automatically determine the transport If it is overweight, the system will alarm if it is overweight.
other functions
System management: Various operating parameters of the system can be set and modified, and the operating status of the system can be adjusted.
Statistical reports: Customize and develop various reports according to requirements for easy statistical summary.
Authority management: can adopt role-based authority management settings to improve the security of the system.
5. Function extension
The transportation vehicles are equipped with sensors for temperature, pressure, inclination angle and leakage of dangerous chemicals. When a dangerous situation is about to occur, the information can be transmitted to the monitoring center through GPRS/CDMA to report to the police in time to prevent accidents.
Install vibration sensors on the transportation vehicles, if the vehicle collides, it will promptly report to the monitoring center, especially in the event of a major accident, when the on-site personnel are no longer able to call for help, the automatic alarm of the sensor is convenient for rescuers to rush to the scene for rescue as soon as possible.
