Abstract

The invention discloses a ZigBee-CAN based information issue terminal. The terminal comprises a determination unit used for determining whether user terminals accessing a network are specific user terminals needing data reception or not; a quantity estimation sub-unit used for estimating the quantity of the user terminals in the network; a transmitting unit used for receiving data information transmitted by a temperature sensor and transmitting data signals to a CAN bus controller; a CAN bus control unit used for receiving CAN network transmission instruction data signals and transmitting monitoring data through a CAN bus protocol; a ZigBee transmitting-receiving unit used for receiving ZigBee network monitoring data and transmitting instruction data to the specific user terminals. The terminal realizes communication connection between a wired network and a wireless network and is advantaged by security, low price, high reliability, easy expansion, and the like.

Description

technical field [0001] The invention relates to the field of network technology, in particular to an information publishing terminal based on ZigBee-CAN. [0002] Background technique [0003] With the development of wireless communication technology, wireless communication equipment continues to mature, and the cost is further reduced. However, in areas where the working environment is relatively harsh and wiring is difficult, the cost of providing wired networks is relatively high; wireless transmission networks can solve this problem , but the transmission distance and transmission quality of the wireless transmission network are limited. [0004] The inventor found in the process of research that CAN bus, as a mature field bus technology, has the characteristics of high reliability, good real-time performance and low cost; ZigBee wireless communication technology has low cost, low power consumption, low speed and Working in the license-free frequency band, it can be wi...
