Abstract

The invention discloses a wireless communication system based on wireless sensors. The wireless communication system comprises a wireless gateway and at least one wireless sensor. A wireless channel connection is established between the wireless sensors and the wireless gateway. When being required to sense information, the wireless gateway broadcasts multiple wakeup packets including a unique code. The wireless sensor performs carrier sense on a wireless channel at a first time window of a WOR wakeup period, receives the wakeup packets if finding a carrier, and then enters a work period to acquire sensed data at a first time segment in the work period and transmit the sensed data and an identification code corresponding to the wireless sensor to the wireless gateway at a second time window. By means of the above way, the wireless communication system may achieve bidirectional communication of the wireless sensor, and is low in power consumption and resistant to collision.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a wireless communication system based on wireless sensors. Background technique [0002] As a new information technology, the Internet of Things can realize informatization, remote management control and intelligence between people and things, things and things. In the existing Internet of Things technology, wireless sensors are usually used as nodes for information collection. [0003] A wireless sensor is a sensor with a power supply battery, a sensing module and a radio frequency module inside itself. Existing wireless sensors usually collect sensing information according to a fixed period and communicate one-way, that is, only transmit signals, in order to save power consumption and increase the power supply time of the power supply battery. However, one-way communication cannot follow the instructions of the control center. In fact, a lot of information co...
