Problems solved by technology

However, it has obvious shortcomings in actual use, that is, it cannot realize effective information transmission from upper-layer equipment to lower-layer dormant nodes.
Once the upper layer needs to operate on the lower layer, when transferring data, since the upper layer device cannot know when the underlying device sleeps and wakes up, this communication method cannot be implemented or is extremely unreliable

Embodiment Construction

[0033] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0034] refer to figure 1 As shown, the ZigBee-based communication system of this embodiment includes an upper-layer device, a wake-up device, and a low-power terminal node. Wherein, the wake-up device includes a ZigBee sending module and a ZigBee receiving module, and the ZigBee sending module and the ZigBee receiving module respectively occupy different channels. The ZigBee sending module is used to continuously send control instructions to the low-power terminal nodes when the upper device needs to send control instructions to the low-power terminal nodes. Its specific process is as figure 2 shown.

[0035] combine image 3 As shown, the ZigBee receiving module is used for continuous short-term channel monitoring (the time occupied by channel monitoring does not exceed 1 / 100 of the wake-up cycle of the low-power terminal node); if no data info...

Abstract

The invention discloses a communication system and an awakener based on a double-channel ZigBee. The awakener comprises a ZigBee sending module and a ZigBee receiving module, wherein the ZigBee sending module can continuously send a control instruction to a low-power-consumption terminal node, so that once the low-power-consumption terminal node is awakened, data transmission can be realized, and quick awakening is realized; the ZigBee receiving module continuously intercepts frequency channels and correspondingly processes the type of data information if the data information is intercepted; and therefore, bidirectional reliable communication between the awakener and the low-power-consumption terminal node in a wireless sensor network is realized.

Description

technical field [0001] The invention relates to a wireless sensor network technology, in particular to a communication system and a dual-channel ZigBee-based wake-up device. Background technique [0002] The nodes of the wireless sensor network are often powered by batteries. In order to control the power consumption of the nodes, the main energy-consuming modules in the nodes are often turned off when they are idle to ensure low-power operation. This leads to the inability of nodes to communicate in real time, and also limits the way nodes send and receive information. The distributed mode of wireless sensor network exists, and at the same time, because the time of each node cannot be accurately synchronized, it is impossible to accurately judge the wake-up of the node, so that the reliability of communication cannot be guaranteed. [0003] In order to solve the data collection and transmission requirements in wireless sensor networks while reducing power consumption as mu...
