During the animal health supervision practices，some problems always existed，such as the inadequate production data，low informationalized level，as well as the broken traceability information chain. In order to solve these problems，through the technology integration of Internet of Things，Big Data and mobile internet，a supervision system for livestock product quality and safety named as“Chengdu Smarter Animal Health Inspection System”was completely established，which has digitized the supervision service and significantly enhanced the capacity of epidemic management and animal health supervision. Here，the construction idea，overall framework，essential components and operation mechanism were introduced. In addition，the development directions of continuously progressing core technology，standards and specifications，analysis and application of big data and marketization service were also prospected，hoping to provide some reference for upgrading the working mode of animal health service.
