Problems solved by technology

[0006] However, in practical applications, the distance between receiving and transmitting equipment is not fixed, or may change frequently, and it is difficult to know how much transmit power can meet the coverage requirements while reducing interference: if the transmit power is too small, the Leading to the failure of normal communication; if the transmission power is too high, it will cause great interference to other surrounding devices
[0007] It can be seen that it is difficult to solve the above technical problems by artificially adjusting the transmission power in the traditional frequency hopping communication method

Embodiment 1

[0079] See this example for example Figure 5 The flow diagram of the method for automatically adjusting the transmission power in the frequency hopping communication shown, the flow includes the following steps:

[0080] Step 1: After the device is powered on, the transceiver device communicates with the maximum transmission power on a fixed channel, completes initialization, and establishes a connection.

[0081] Step 2: The transceiver device randomly switches to a certain channel X, and the sending device sends data packets with the maximum transmission power.

[0082] Step 3: The transceiver device randomly switches to other channels to continue communication.

[0083] As mentioned above, you can set the number of data packets sent and received by the transceiver device on the same channel, or set the maximum stay time of the transceiver device on the same channel. When the set conditions are met, the transceiver device will switch from the current channel to other chann...

Embodiment 2

[0100] Figure 7 It is a schematic flowchart of a method for automatically adjusting transmission power in frequency hopping communication in Embodiment 2 of the present application, see Figure 7 , the process includes the following steps:

[0101] Step 1: After the device is powered on, the transceiver device communicates with the maximum power on a fixed channel, completes initialization, and establishes a connection.

[0102] Step 2: The transceiver device randomly switches to a certain channel X, and the sending device sends data packets with the maximum transmission power.

[0103] Step 3: The transceiver device randomly switches to other channels to continue communication.

[0104] As mentioned above, you can set the number of data packets sent and received by the transceiver device on the same channel, or set the maximum stay time of the transceiver device on the same channel. When the set conditions are met, the transceiver device will switch from the current channe...

Abstract

This application discloses a method and device for automatically adjusting transmission power in frequency hopping communication. When switching to the target channel for the first time, the sending device sends data packets with the set transmission power; the target channel is any channel in frequency hopping communication ; Before the first packet loss occurs on the target channel, whenever switching back to the target channel, reduce the transmitting power of the sending device on the target channel until the first packet loss occurs on the target channel, increase the transmitting power of the sending device on the target channel, and start Statistically calculate the first data used to calculate the first parameter; then, whenever switching back to the target channel, calculate the first parameter of the target channel according to the first data, and adjust the transmission of the sending device on the target channel according to the first parameter of the target channel Power; wherein, the first parameter is used to characterize the communication quality of the target channel. By applying the technical solution disclosed in the present application, the coverage requirements of the transmitting and receiving parties can be met, and the interference to other devices can be reduced at the same time.

Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular to a method and device for automatically adjusting transmission power in frequency hopping communication. Background technique [0002] Frequency hopping is one of the most commonly used spread spectrum communication methods. Its working principle is: the carrier frequency of the transmission signal transmitted by both parties is discretely changed according to a predetermined law, that is to say, the carrier frequency used in communication is controlled by the pseudo-random change code. Jump randomly. In frequency hopping communication, a certain entire spectrum is divided into multiple channels, each channel occupies a certain bandwidth, and each carrier frequency corresponds to a channel. During the communication process, the receiving and sending parties change the channel at regular intervals to achieve the purpose of anti-interference. [0003] The t...
