Embodiment Construction

[0042] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0043] figure 1 It is a flowchart of a method for preventing multi-user terminal access conflicts provided by an embodiment of the present invention, as shown in figure 1 As shown, the steps include:

[0044] Step S101: Pre-assign a unique user identifier ID to each user terminal working in time division mode.

[0045] Further, when the number of user terminals is large, the user identifiers IDs of each user terminal may be grouped, so that multiple activated user terminals are grouped into an access queue for accessing the network. For example, the user terminal is divided into two groups, the grouping base number of the first group is 0xxH, and the gr...

Abstract

The invention discloses a method and device for preventing access collision of multiple user terminals. The method comprises the following steps: a specific user ID is allocated for each user terminal working in a time division mode in advance; when multiple user terminals working in a time division mode are activated at the same time and access a network, each user terminal determines a corresponding network access time slot according to the allocated user ID so that the user terminals activated at the same time forms an access queue for accessing the network; and each user terminal in the access queue accesses the network in sequence according to the determined time slot and sends data frames. The method has the advantages of largely reducing access collision and improving the use rate of channels when multiple user terminals are activated at the same time and need network access.

Description

technical field [0001] The invention relates to the field of micro-power Internet of Things, in particular to a method and device for preventing multi-user terminal access conflicts. Background technique [0002] The modern world is a world of high-speed automation. In addition to being connected to computers, various devices can also be connected to each other. The easiest way to connect to automation is to use serial communication. Today, compared with wired technology, wireless technology has the advantages of low cost, easy portability, and no need for wiring. It is widely used in various devices and systems, such as handheld devices, battery-powered devices, industrial data acquisition systems, wireless remote control systems, intelligent communities Non-parking charging system, etc. The quality of the wireless communication protocol is directly related to the security of the system, the bit error rate and the speed of the system operation. Therefore, in various wirele...
