Heartbeat method based on TC wireless networking communication product

Abstract

The invention provides a heartbeat method based on a TC wireless networking communication product, and the wireless networking comprises wireless control end equipment and at least one wireless receiving end equipment. The heartbeat method comprises the steps that (1) the wireless control end equipment distributes heartbeat information to the wireless receiving end equipment according to a protocol; (2) the wireless control end equipment and all the wireless receiving end equipment unify time reference; (3) under the same time reference, each piece of wireless receiving end equipment calculates heartbeat time sent by the corresponding wireless receiving end equipment in a sequence mode according to the address and the heartbeat interval of the wireless receiving end device; (4) all the wireless receiving end equipment actively and sequentially sends heartbeats to the wireless control end equipment according to heartbeat time in a self-number-reporting mode; (5) after receiving the heartbeat sent by the wireless receiving end equipment every time, the wireless control end equipment replies data to the corresponding wireless receiving end equipment, and bidirectional confirmation is carried out. According to the invention, the problem of heartbeat time sequence is considered when the product accesses the network, so that the problem of co-frequency interference is effectively avoided.

Description

technical field [0001] The invention relates to a heartbeat method based on TC wireless networking communication products, belonging to the technical field of wireless communication. Background technique [0002] When communicating with wireless devices, if you want to ensure normal and stable communication during operation, heartbeat sending and receiving between products is an essential function. If the heartbeat processing between wireless devices is not good enough, there will be serious co-channel interference, which will lead to communication failures during wireless communication, which will directly affect the use of the devices. Therefore, only an accurate heartbeat solution can ensure the normal operation of wireless devices. communication. [0003] Traditional wireless networking communication products can achieve normal and stable communication when the heartbeat interval is long, but when the heartbeat interval is short, there will be a high probability of co-f...

AI Technical Summary

Problems solved by technology

Although the above-mentioned patent can solve the communication problem between wireless networking communication products to a certain extent, in the actual application process, because it uses the control node to actively send heartbeat information to the controlled node according to the broadcast message and scheduling message, so in the application For wireless firefighting equipment with a short heartbeat interval, the above problems still exist, that is, when the heartbeat interval is long, the communication can be normal and stable, but when the heartbeat interval is short, there will be a high probability that some wireless receivers will Co-channel interference of equipment and failure of data reporting
