Problems solved by technology

[0003] At present, in the Zigbee network, there are many types of sensors. The traditional data transmission method is that one sensor corresponds to one transmission method, that is, for each different type of sensor, the data collected by the sensor is encapsulated by a specific protocol, and then Transmission to the back-end server, this data transmission method is difficult to adapt to multi-source sensors, and increases the complexity of the back-end server when parsing data

Embodiment 1

[0072] Embodiment 1 provides a kind of multi-source data transmission method based on Zigbee network, comprises the following steps:

[0073] S1. The sending end collects the data of the sensor, and processes it according to the format of the general frame: the general frame includes the data field, loads the collected data into the data field of the general frame, and edits the frame header of the data field of the loaded general frame, The end of the frame is respectively replaced, encapsulated into several first data frames, and all the first data frames are arranged according to the order of the collected data.

[0074] The format of the general frame is: frame header (3 bytes) + frame identification (1 byte) + serial number in the current frame (1 byte) + remaining number in the current frame (1 byte) + short address of the slave node ( 2 bytes) + data field (n≤18 bytes) + CRC check (2 bytes) + frame end (3 bytes), n is a positive integer.

[0075] The resulting first da...

Embodiment 2

[0098] Embodiment 2 provides a Zigbee network-based multi-source data transmission method, except that the format of the general frame in steps S1 and S3 is different from that of Embodiment 1, and the rest of the steps are the same.

[0099] In order to realize the inspection function, the format of the general frame in embodiment 2 is: frame header (3 bytes)+frame identification (1 byte)+current frame sequence number (1 byte)+residual number in the current frame frame ( 1 byte) + slave node short address (2 bytes) + data domain (n≤18 bytes) + CRC check (2 bytes) + frame tail (3 bytes), n is a positive integer, the obtained The data field of a first data frame includes TransactionMode (business mode), and TransactionMode is used to select a function to be implemented. In this embodiment, TransactionMode selects an audit function.

[0100] The resulting first dataframe is as follows:

[0101] The first data frame 1 (data length 19 bytes)

[0102]

[0103] The first data f...

Embodiment 3

[0118] Embodiment 3 provides a Zigbee network-based multi-source data transmission method, except that the format of the general frame in steps S1 and S3 is different from that of Embodiment 1, and the rest of the steps are the same.

[0119] In order to realize the communication function, the format of the general frame among the embodiment 3 is: frame header (3 bytes)+data domain length (1 byte)+data domain (n bytes)+CRC check (2 bytes)+ Frame end (3 bytes), n is a positive integer.

[0120] The resulting first dataframe is as follows:

Abstract

The invention discloses a multi-source data transmission system based on a Zigbee network and relates to the field of wireless data transmission. A sending end of the system collects data of a sensor and processes the data according to a format of a general frame for packaging the data into a plurality of data frames; judges whether the length of each data frame is greater than 32 bits or not, divides, re-framing and arranging the data frames whose lengths are greater than 32 bits and performs frame verification of the data frames whose lengths are smaller than or equal to 32 bits; and transmits the data frames subjected to frame verification. A receiving end receives and detects the data frames; judges whether the frame footer of a data domain is detected or not, repeats receiving detection if no frame footer is detected, restores the data subjected to replacement treatment and stores if the frame footer is detected until all the data frames are received, detected and restored. Finally, the data collected by the sending end is acquired. According to the invention, uniform transmission of multi-source sensor information is realized, adaptability to the multi-source sensor is improved and complexity in data analysis of a rear-end server is reduced.

Description

technical field [0001] The invention relates to the field of wireless data transmission, in particular to a multi-source data transmission system based on Zigbee network. Background technique [0002] Zigbee, translated as "Zigbee" in China, is an emerging short-distance, low-power, low-cost, low-complexity, self-organizing wireless communication technology, similar to Bluetooth, and is mainly suitable for automatic control and remote control field, which can be embedded in various devices. [0003] At present, in the Zigbee network, there are many types of sensors. The traditional data transmission method is that one sensor corresponds to one transmission method, that is, for each different type of sensor, after the data collected by the sensor is encapsulated by a specific protocol, and then Transmission to the back-end server, this data transmission method is difficult to adapt to multi-source sensors, and increases the complexity of the back-end server when parsing data...
