Embodiment

[0019] Example: as attached figure 1 As shown, the general-purpose PC 3 is used to run data processing and display software. There are 8 wireless collection nodes in the system, that is, the first to eighth wireless collection nodes N1, N2, ... N8. The wireless convergence node 2 is based on the CC2530 chip design of Texas Instruments, and works in the 2.45GHz frequency band. attached figure 2 For the time slot allocation method of the present invention, in the figure: the wireless convergence node allocates time slots of suitable length according to the amount of data collected by each wireless collection node: node 1 time slot, node 2 time slot....node N time slot .

[0020] In the embodiment, the system adopted by the wireless data collection method consists of 8 wireless collection nodes first, second, ... the eighth N1, N2, ... N8 and 1 wireless convergence node 2, a general-purpose PC Machine 3 and data processing and display software constitute. N wireless collect...

Abstract

The invention relates to a wireless data collecting method based on dynamic time slot allocation, and belongs to field of data collecting and wireless communication application. According to the wireless data collecting method, a plurality of wireless collection nodes are evenly distributed around a wireless sink node; transmission timeslots and timeslot lengths of the wireless collection nodes are dynamically controlled by the wireless sink node according to the number of data collected by each collecting node; the timeslot length distributed to each wireless collection node is in direct proportion to the number of data collected by the node; distributed data collecting is achieved by the wireless collecting nodes in cooperation with each other, and data are sent to the wireless sink node; the data are sent to a PC by the wireless sink node and are analyzed and processed by data processing software on the PC, and the result is displayed afterwards. The wireless data collecting method based on dynamic time slot allocation facilitates arrangement and installation, effectively improves data transmission efficiency of a distributed data collecting system, and has wide application prospects in fields like industrial monitoring and military.

Description

technical field [0001] The invention belongs to the fields of data collection and wireless communication applications, and relates to a wireless data collection method based on dynamic time slot allocation. Background technique [0002] The data acquisition system has a wide application prospect in the fields of industry, military affairs, agriculture and so on. In the industry, it is often necessary to measure the parameters of various equipment online. For example, the oil drilling platform needs to monitor the pressure, speed and other parameters of multiple points on the platform in real time; the coal excavation surface needs to monitor the pressure, gas concentration and displacement of multiple points on the excavation surface in real time and other parameter information; large bridges need real-time monitoring of their bridge deck vibration, swing, pressure and other parameter information; super high-rise buildings need real-time monitoring of their staircase vibrati...
