Embodiment

[0022] figure 1 It is a principle schematic diagram of a specific embodiment of the low-power wireless data acquisition system of the present invention.

[0023] In this example, if figure 1 As shown, the low-power wireless data acquisition system includes a data processing server S, a ZigBee wireless personal area network Z, and multiple data acquisition nodes T.

[0024] In this embodiment, the ZigBee wireless personal area network Z includes three ZigBee router nodes, one ZigBee coordinator node and three data convergence nodes.

[0025] The data acquisition nodes are divided into three groups: the first group has I 1 1 ~1 I , the second group has J 2 I ~2 J , The third group has K 3 1 ~3 K Corresponding to data aggregation nodes 1-3 respectively. A low-power wireless data acquisition system consists of two processes:

[0026] 1. Data collection process

Abstract

The invention discloses a low-power wireless data acquisition system comprising a data processing server, a data acquisition node and a ZigBee wireless personal area network, wherein the data acquisition node comprises at least one sensor module and a wireless transmit-receive module, the sensor module takes charge of acquiring data, and the wireless transmit-receive module takes charge of transmitting the acquired data; and the ZigBee wireless personal area network also comprises at least one data convergence node with a ZigBee terminal, takes charge of receiving the acquired data from the data acquisition node, packs into ZigBee network data and then transmits to a ZigBee router node or a ZigBee coordinator node. The invention enables the whole system to achieve ideal cluster tree topology under an easiest condition and have lower powder consumption relative to the traditional wireless network applying the cluster tree topology and omits the secondary development of a network layer of a ZigBee protocol by combining a point-to-point wireless transceiver with the ZigBee wireless personal area network, thereby greatly shortening the development period.

Description

technical field [0001] The invention belongs to the technical field of data acquisition, and more specifically relates to a low-power consumption wireless data acquisition system. Background technique [0002] At present, ZigBee technology is used more and more in the field of data acquisition and wireless sensor network (WSN). ZigBee technology is a short-distance, low-complexity, low-speed two-way wireless communication technology, mainly used for data transmission between various electronic devices with short distances and low transmission rates and typical periodic data, intermittent data and low latency data transmission applications. [0003] ZigBee wireless network is mainly composed of ZigBee coordinator, ZigBee router and ZigBee terminal. In the prior art, the application of ZigBee wireless network in the field of data acquisition is mainly to embed the data acquisition device in the ZigBee terminal as the acquisition node, but in some specific occasions, especial...
