Problems solved by technology

[0005] The problem existing in the existing ZigBee data acquisition system is that the data collected by the system is usually transferred and output by the coordinator. When the amount of collected data is large, this single-channel output is likely to cause data blockage
In addition, when the channel is abnormal, the data transmission will be directly interrupted, which may easily cause data loss

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] The data collection system based on ZigBee communication proposed by the present invention includes a server, multiple transfer devices and multiple collection terminals. The acquisition terminal obtains external data, and transmits the data to the relay device through the Zigbee network, and the relay device is then connected to the local area network, and the data is sent to the server for storage. Each transit device can establish an independent transmission data channel.

[0026] In order to be able to automatically select the transfer device for transmission of collected data, the system adopts the following working methods.

[0027] Add collection terminal situation

[0028] Step 1: When the newly added collection terminal is powered...

Abstract

The invention relates to a data acquisition system based on ZigBee communication. The system comprises a server, a plurality of transfer apparatuses and a plurality of acquisition terminals. When each acquisition terminal uploads data, one transfer apparatus is randomly selected in the plurality of transfer apparatuses so as to carry out transmission so that a data obstruction condition is reduced. By using a system response mechanism, when one transfer apparatus has a fault, other channels are automatically adjusted to so that a data loss condition caused by a channel fault is avoided and stability and robustness of a communication system are increased.

Description

technical field [0001] The invention relates to a data acquisition system based on ZigBee communication. Background technique [0002] ZigBee is a low-power LAN protocol based on the IEEE802.15.4 standard. ZigBee technology is characterized by short distance, low complexity, self-organization, low power consumption, and low data rate. It is mainly suitable for the fields of automatic control and remote control, and can be embedded in various devices. In short, ZigBee is a cheap, low-power short-range wireless networking communication technology. [0003] ZigBee technology uses dynamic routing to organize the network. Dynamic routing means that the path of data transmission in the network is not pre-set, but before data transmission, by searching all the paths available on the network at that time, analyzing their positional relationship and distance, and then selecting one of the paths for routing. data transmission. The path selection can use the "gradient method", tha...
