Ultrahigh frequency RFID and sensor network synthesis controller

Disclosed is a synthesis controller of ultra-high frequency RFID and sensor network, which comprises a microprocessor, an ultra-high frequency RFID read-write module, a sensor network radio frequency communication module, an expanding Flash, an expanding RAM, an extendable I/O interface, a temperature and humidity sensor, a network communication module and a display module respectively connected with the microprocessor, and a power supply providing electrical source for the system as well as a management module. The network communication module selects the mode of Ethernet or RS485 bus to communicate with a control computer. The extendable I/O interface includes general input and output pins, an SPI interface, an I C interface and a UART interface. The controller forms a hazardous chemical warehousing supervision system which integrates warehousing management and warehouse monitoring into one and comprehensively applies the RFID technique and sensor network technique. The recognition to targets such as personnel, goods and vehicles can be realized based on the RFID technique, and the intelligence of warehousing environment can be realized based on the sensor network technique, thereby meeting the requirements of distributed monitoring on environmental parameters such as temperature, humidity and ingredients and jointly providing the basic data for the hazardous chemical warehousing supervision system.
