Problems solved by technology
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 collected according to timing is not required by the control center, resulting in a large amount of garbage data, which also increases the workload of wireless sensors and increases power consumption
Moreover, if the existing wireless sensors use two-way communication, they need to be in a high-current monitoring state for a long time, resulting in very large power consumption and cannot be powered by disposable batteries.
Therefore, the existing wireless sensors can only achieve two-way communication or low power consumption unilaterally, and cannot achieve both
[0004] There is still a problem with existing wireless sensors. If multiple wireless sensors communicate with the same control center in an environment, wireless signals will collide in the air, causing the collected signals to be unable to be accurately transmitted to the control center.

The invention discloses a wireless communication system based on a wireless sensor. The wireless sensor carries out the monitoring of a wireless gateway channel through the bidirectional channel transmission of a wireless gateway and at least one wireless sensor, selects an information package comprising a recognition code for response, and completes the data communication with the wireless gateway. The system achieves the bidirectional communication of the wireless gateway and the wireless sensor in the above mode, is low in power consumption, and is resistant to collision.
Description
Technical field [0001] This application relates to the field of communication technology, and 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 sensor module, and a radio frequency module inside. Existing wireless sensors usually collect sensing information in a fixed period and only transmit signals in one-way communication to save power consumption and increase the power supply duration of the power supply battery. However, one-way communication cannot be achieved in accordance with the instructions of the control center. In fact, a lot of information collected accord...
