Problems solved by technology
[0004] In terms of software, similar wireless serial port module products at home and abroad are mainly based on Zigbee technology, which has a large amount of code, which makes the system cost high and consumes a lot of power.
Moreover, when two subnets based on Zigbee technology coexist, they will interfere with each other, and communication collisions will occur. Data communication in one subnet will wake up the other subnet, thereby reducing communication efficiency, and the power consumption of the system will increase accordingly.

The invention relates to a short-distance wireless communication system based on an IEEE802.15.4 technique, which consists of a transmission layer and a serial universal module, wherein the transmission layer and the serial universal module are connected in a wireless way based on the IEEE802.15.4 technique. The short-distance wireless communication system has the advantages that the structure of a hardware part is simple, and the short-distance wireless communication system can be configured and connected according to the actual condition of the site, so that a plurality of wireless and wire communication techniques can be organically combined to ensure that the functions of the short-distance wireless communication system are more complete and the application of the short-distance wireless communication system is more extensive; a soft part is an improvement based on the IEEE802.15.4 technique, so that the system has lower cost, less power consumption, strong anti-interference capability and high communication efficiency.
Description
Technical field: [0001] The invention belongs to the technical field of short-range wireless communication, and in particular relates to a short-range wireless communication system based on IEEE802.15.4 technology and a software program applicable to the system. Background technique: [0002] At present, the communication platforms used for wireless monitoring at home and abroad are mainly composed of scattered nodes relying on GPRS / GSM SMS or traditional analog communication technology. / GSM node monthly fee, and node power consumption is also large, not suitable for battery power supply, inconvenient to use. [0003] In terms of hardware, several companies at home and abroad are engaged in the development and sales of similar short-range wireless general-purpose modules, but most of their products are concentrated in wireless serial port modules. In many applications, data needs to be transmitted to computers or servers quickly; in other applications, such as field enviro...
