Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] Such as figure 1 As shown, in this embodiment, a method for a wireless gateway to automatically select an idle working frequency point includes the following steps:
[0022] Step 1. When the wireless gateway newly establishes a network, the wireless gateway sends a frequency point search frame through an overlay call;
[0023] Step 2. Other network node modules within the jurisdiction of the wireless gateway will respond if they receive the frequency point search frame;
[0024] Step 3. If the wireless gateway receives a response, it considers the frequency point to be occupied, then adjusts the frequency point and returns to step 1; if it does not receive a response and confirms the preset number of times, it considers the frequency point to be free, and the wireless gateway Set this frequency point as the working frequency point.

The invention discloses a method for automatically selecting idle working frequency points by a wireless gateway and a computer readable storage medium, and belongs to the field of wireless ad hoc network communication systems. The method comprises the following steps: step 1, when a wireless gateway newly builds a network, the wireless gateway sends out a frequency point search frame in an overlay calling mode; step 2, other network node modules within the jurisdiction of the wireless gateway respond if receiving the frequency point search frame; step 3, if the wireless gateway receives a response, considering that the frequency point is occupied, adjusting the frequency point and returning to the step 1; and if the response is not received and is confirmed for a preset number of times, the frequency point is considered to be idle, and the wireless gateway sets the frequency point as a working frequency point. When a network is newly built, a new idle working frequency point is foundby automatically avoiding an existing ad hoc network working frequency point nearby. Therefore, the wireless signal collision interference is avoided.
Description
technical field [0001] The invention belongs to the technical field of Internet of Things wireless communication, and specifically relates to a method for a wireless gateway to automatically select an idle working frequency point and a computer-readable storage medium. Background technique [0002] Wireless networks have been widely used in the field of Internet of Things, many of which work in the form of ad hoc networks. When building a new wireless network, engineering personnel need to have detailed records of the working frequency points of nearby networks and strictly manage them by area. Otherwise, the working frequency points of the newly built network will collide with the existing network, causing signal interference. In addition, in the process of production and warehouse management, wireless gateways of different frequency points need to be produced, marked, stored and transferred in different categories, which increases the difficulty and cost of management. ...
