Abstract: 【Objective】 The purpose of the study was to trace vehicles for the transport and harmless handling of pigs die of diseases from the harmless treatment plant to the circulation of safety traceability between collection points. 【Method】The system takes the transport vehicle for the harmless treatment of dead pigs as the research object. The system frame is designed with a three layer structure: a data service layer, a data processing layer, and a data collection layer. The data collection layer is composed of Beidou/GPS dual mode receiver, a temperature sensor, a wireless radio frequency reader, an active electronic label, and a GPRS wireless transmission module. The study sought to collect the transport vehicle location information, compartment temperature information, and disinfection point vehicle active electronic tag information of the traceability safety system of the transport vehicle for harmless handling of dead pigs, and then transfer this data. The location information of the transport vehicle is mainly gathered by use of the collected data of the Beidou navigation and positioning system. The GPS navigation and positioning data from the WGS-84 coordinate system was converted to the BJ-45 coordinate system of the Beidou navigation and positioning system, and the GPS navigation and positioning system was used to modify the data when the Beidou navigation positioning system data appeared to show a larger deviation, to achieve the purpose of improving the acquisition accuracy of the transport vehicle location information. The data processing layer was implemented to extract, modify, and store the collected data. The data service layer mainly provided information services for the staff and monitoring department. This system was developed by using C# language in a Studio Visual 2010 integration environment and using SQL language to store and modify the data in the database server SQL 2008. 【Result】 The function of the system includes route safety management, disinfection safety management, temperature monitoring, control management, health and epidemic prevention management, and safety pre-warning management. An ant colony algorithm was used to carry out the simulation of transport vehicle path planning for the harmless handling of dead pigs away from large farms, living groups, and other areas in the driving region. The simulation result was realistic, and it provides a reference for transport vehicles for the harmless handling of dead pigs to plan a reasonable path in the designated transport area. The traceability safety system of the transport vehicle for the harmless handling of dead pigs provides management staffs of harmless treatment plants with monitoring of transport vehicles, intelligent allocation of transport vehicles, compartment temperature monitoring, and vehicle information query functions. The system carried out on-site testing in a harmless handling of dead pigs pilot plant in Lianshui County, Jiangsu Province. The result showed that the hardware module of the system runs stably, the network packet loss rate was 0.26%, and the vehicle identification error rate was 0.97%. Through the ArcGIS monitoring and management function module, continuous monitoring of the transport vehicles running routes was done for 2 hours. Testing of the temperature monitoring management function, and the disinfection safety management function showed that each module of the system was working properly, and met the requirements of the traceability safety system of the transport vehicle for the harmless handling of dead pigs. Meanwhile, it can provide services for a monitoring and management department of animal health and epidemic prevention through the monitoring client by means of telephone, network, and short messages. It can also send the monitoring data such as vehicle running route, compartment temperature, and other information to the supervision department in real time to realize the implementation of the comprehensive supervision and management of a transport vehicle for the harmless treatment of dead pigs and ensure animal health and safety. 【Conclusion】This study has provided an effective method off safety management for a transport vehicle for the harmless treatment of dead pigs, accomplished the comprehensive supervision and management of transport vehicle for the harmless treatment of dead pigs, and reasonably avoided the occurrence of animal health and safety incidents. As it provides a reference for other harmless treatment of dead pigs die of diseases integrated management systems, it has practical value.
