Communication protocol switching method, data transmission method, wireless sensor and system

Abstract

The embodiment of the invention discloses a communication protocol switching method, a data transmission method, a wireless sensor and a system. The communication protocol switching method comprises following steps of automatically switching the communication protocol of the wireless sensor from a first communication protocol to a second communication protocol when the wireless sensor can obtain electric energy from a wireless charging base; and transmitting stored data to the wireless charging base through the second communication protocol when the wireless sensor establishes communication connection with the wireless charging base. According to the methods, the sensor and the system, when the wireless sensor is charged, the communication protocol is automatically switched, and therefore the data stored by the wireless sensor can be transmitted to the wireless charging base. Compared with the prior art, the methods, the sensor and the system have the advantages that the communication protocol can be automatically switched, the data is transmitted, matching errors are avoided, and therefore data loss is avoided.

Description

technical field [0001] The invention relates to a wireless sensor, in particular to a communication protocol switching method applied to a wireless sensor, a wireless sensor and a system. Background technique [0002] Because low-power wireless sensors generally cannot meet the power consumption requirements of high-speed standard protocols, in order to meet low power consumption, compatibility and bandwidth requirements at the same time, it is necessary to integrate low-speed standard protocols and high-speed sensors on a low-power and low-cost wireless platform. Non-standard protocol, switch according to specific needs. When users need to connect with personal smart devices such as mobile phones and tablets, switch to standard protocols; when users need to transmit large amounts of data through high-speed and low-power consumption with special devices, switch to high-speed non-standard protocols. However, at present, the protocol switching of the product needs to be carri...

Problems solved by technology

Since the operation process involves multiple steps such as protocol selection, scanning, pairing, and confirmation, it is very cumbersome. When there are multiple devices in a short distance, matching errors are often prone to occur, resulting in data loss
