Embodiment 1

[0046]Example 1: Limiting conditions, set the signal strength of the central router to -52dbm at a certain moment when there is no interfering device, and set the number of interfering devices at different times to be 1 or 2 when there is an interfering device 3. When the above-mentioned interference devices exist, the signal strength of the central router is -57dbm, -60dbm, -67dbm, and the difference between the signals generated by different numbers of interference devices is set as L. According to the formula:

[0047]

[0048] The calculated difference between the signals generated by different numbers of interference devices is -5dbm. When estimating the signal strength of the center router for different interference devices, the estimated data is fed back to the wireless channel quality adjustment module to adjust the channel quality of the center route.

Embodiment 2

[0049] Embodiment 2: Restricted conditions: Restricted conditions, set the signal strength of the central router to be -51dbm when there is no interfering device at a certain moment, and set the situation where there is an interfering device, wherein the number of interfering devices at different times is 1, 2, 3, 5, when the above-mentioned interference devices exist, the signal strength of the central router is -53dbm, -57dbm, -60dbm, -68dbm, and the difference between the signals generated by different numbers of interference devices is set to L, According to the formula:

[0050]

[0051] The calculated difference between the signals generated by different numbers of interference devices is -4.25dbm. When estimating the signal strength of the center router for different interference devices, the estimated data is fed back to the wireless channel quality adjustment module to adjust the channel quality of the center route.

Embodiment 3

[0052] Embodiment 3: restrictive conditions, the total length of the data link of the wireless channel of the described setting current center router at a certain moment is 5600 bits, and the number of links is 4, and the delay time of each link is 0.2 second, and the current channel The data transmission rate is 5600bps, and the data delay time is set to Z, according to the formula:

[0053]

[0054] It is calculated that the time delay of the wireless channel at a certain moment of the current central router is 1.8 seconds, and the set threshold is 2 seconds. If the set threshold is not exceeded, no processing is performed.

Abstract

The invention discloses a signal receiving adjustable system based on data communication. The system comprises a central routing configuration information acquisition module, a different-moment signal strength monitoring module, an adjacent wireless equipment interference module, a wireless channel quality adjusting module and a quick response communication center. The central route configuration information acquisition module acquires basic configuration of a central router for wireless signal transmission, the signal strength monitoring module monitors route signal strength at different moments, and the adjacent wireless device interference module acquires the number of interference devices at adjacent positions of a route. The wireless channel quality adjusting module adjusts the quality of a wireless channel according to the detected route signal strength, the quick response communication center responds to the adjustment of the signal strength, so that the number of interference devices around the central router is detected, the influence degree of the interference devices on signals is monitored, and the signal propagation speed of the central router is sent to a user in real time for checking.

Description

technical field [0001] The invention relates to the field of data communication, in particular to an adjustable signal receiving system based on data communication. Background technique [0002] Data communication is a new communication method produced by the combination of communication technology and computer technology. To transmit information between two places, there must be a transmission channel. According to different transmission media, there are wired data communication and wireless data communication. But they all connect the data terminal and the computer through the transmission channel, so that the data terminals in different places can share the software, hardware and information resources. [0003] The signal is the electromagnetic code of data, and the signal contains the data to be transmitted. Signals generally take time as the independent variable, and a certain parameter (amplitude, frequency or phase) representing the message (or data) as the dependen...
