In this system, a vehicle transport recorder is developed to record the operations of inputs and outputs of a tank truck via a kind of Hall Effect switch sensors. Wireless data transceivers are designed to start and stop monitoring in the starting stations and destinations automatically. The information recorded by the vehicle transport recorder is collected by a smart card and then it is transferred to the host management software which is developed to manage the transportation data, alarm messages, devices, archives, etc. The integrated and intelligent system has been implemented and applied to practice, and it reduces the loss of petroleum products during the transportation efficiently.   Monitoring, management, tank truck, transportation, smart card, CC1100 chip, wireless data communication.   Nowadays, the wastage of petroleum products in transit becomes higher and higher because of some uncontrollable factors and controllable factors, such as problems of facilities and devices, illegal operations by some people and so on. Along with the increase of petroleum price, the wastage has not only resulted in huge financial loss of petroleum companies, but also brought about the quantity problem of petroleum products. Moreover, it is difficult to monitor and manage the process of tank truck transportation on the spot. Traditionally people use a kind of locking devices, such as lead seals, to lock the input and output (I/O) of a tank truck to prevent illegal operations. However, traditional lead seals can be copied or deciphered easily, and they cannot help people to manage the tank truck transportation conveniently either. In our previous work, we have proposed a management system for tank truck transportation using smart cards [1], and a wireless data acquisition system based on CC1100 chip [2]. In this paper, a novel monitoring and management system for tank truck transportation is presented. It is not a simple electronic lead seal or other locking device, but an intelligent system based on smart card and wireless data communication technologies. In this system, a kind of vehicle transport recorder is developed to monitor I/O of a tank truck via a kind of switch sensors. A wireless data transceiver is developed to seal I/O at the starting station and unseal I/O at the destination automatically. Once an I/O has been sealed, then any opening or closing operation of it is illegal. The vehicle transport recorder records the information about the illegal operations of I/O. The smart card is used to collect the transportation data from the vehicle transport recorder and transfer the data to the host management software which is developed to manage the transportation data, alarm messages, devices, archives, etc. This integrated system links petroleum storage depots, gas stations, petroleum companies and transportation companies together to form a well organized monitoring network. The rest of this paper is organized as follows. In Section 2, some related works are given. In Section 3, the system architecture including the design of vehicle transport recorder is presented. Section 4 shows the approach of wireless data communication which is used in both vehicle transport recorders and wireless data transceivers. In Section 5, the algorithm of transportation data analysis is discussed. Section 6 shows the implementation and results of this system followed by the conclusions.
