The invention discloses a distributed optical wireless-WiFi-Zigbee network comprising an optical wireless exchange system, a distributed host and a several distributed slaves, wherein the optical wireless exchange system communicates with the distributed slaves through a WiFi module, and the distributed host communicates with the distributed slaves through a Zigbee wireless module. According to the distributed optical wireless-WiFi-Zigbee network disclosed by the invention, effective coverage of 50-200m is realized by using the Zigbee wireless communication technology, and the distributed host performs data communication with the distributed slaves through a Zigbee protocol; and the distributed host further transmits data to the optical wireless exchange system through the WiFi. As WiFi access pointS can be concentrated in a control room, multiple distributed slaves can be accessed through the WiFi, the slaves adopt the Zigbee communication technology, therefore each salve does not need to communicate by using the WiFi, which reduces the cost, and in addition, short address inquiry and a communication function according to two bytes are realized by using the Zigbee protocol, thereby effectively improving the reliability, security and flexibility and the system, and realizing the collection of distributed data.
