Description

Technical Field

[0001] The present invention relates to the field of wireless communication, and specifically to a wireless signal communication system and method based on one transmitter and multiple receivers. Background Art

[0002] Signals include data signals and analog signals. An analog signal refers to information represented by a continuously varying physical quantity, and the amplitude, frequency, or phase of its signal varies continuously with time, or within a continuous time interval, the characteristic quantity representing the information can take on any value at any instant. A digital signal refers to a signal whose independent variable is discrete and whose dependent variable is also discrete. In this signal, the independent variable is represented by an integer, and the dependent variable is represented by one of a finite number of digits. In a computer, the magnitude of a digital signal is commonly represented by a binary number with a finite number of bits.

[0003] An analog signal is a form of energy propagation. It refers to a signal that is continuous in time (uninterrupted) and whose numerical amplitude also varies continuously and uninterruptedly (traditional audio and video signals). For example, a sound wave causes the medium it passes through to vibrate, and the sound wave can be measured by its frequency (in cycles per second or Hertz (Hz)). Digital signals are transmitted through a medium by representing binary numbers as electrical pulses (where each pulse is a signal element). The voltage on the line varies between high and low states. For example, a high level can be used to transmit binary 1, and a low level can be used to transmit binary 0. Bandwidth is a term referring to the number of bits transmitted per second through a link.

[0004] During long-distance transmission, signals degrade due to attenuation, noise, and interference from other wires in a wire bundle. Analog signals can be amplified periodically, but if the signal is corrupted by noise, the amplified signal is a distorted one. In contrast, digital signals can be more reliably transmitted over long distances because they can be easily extracted from noise and retransmitted.

[0005] In signal transmission to multiple receivers, it is often sent according to the distance or order of the receivers. However, due to inconsistent receiving performance and signal processing times of different receivers, the signal receiving duration and signal receiving quality at the receivers are different. This application aims to screen different receivers through the historical data of signal reception at the receivers and the virtual reception duration, and directionally select signal receivers for signal reception. Summary of the Invention

[0006] The purpose of the present invention is to provide a wireless signal communication system and method based on one transmitter and multiple receivers to solve the problems in the prior art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

Among them, the transmitter user instruction input acquisition module, the unspecified receiver analysis and selection module, and the transmission time limit adaptation module for different receivers are interconnected through an intranet. The unspecified receiver analysis and selection module and the transmission time limit adaptation module for different receivers are respectively connected to the receiver data reception synchronization response module and the data transmission status real-time feedback module through the intranet;

[0009] The transmitter user instruction input acquisition module is used to obtain the user's instructions at the transmitter, select different receivers for signal transmission according to different user instructions. The unspecified receiver analysis and selection module is used to analyze the performance of different receivers and make selections according to the performance of different receivers. The transmission time limit adaptation module for different receivers is used to monitor and analyze the time limits of the reception times of different receivers. The receiver data reception synchronization response module is used to feedback the successfully received data signal to the transmitter during the process of the receiver receiving data. The data transmission status real-time feedback module is used to monitor the current data transmission status according to the data transmitted internally between the transmitter and different receivers.

[0010] By adopting the above technical solution: The transmitter user instruction input acquisition module includes a receiver data interaction information matching sub-module and a real-time transmitter user instruction decoding and classification sub-module. The receiver data interaction information matching sub-module is used to detect the number of receivers currently connected to the transmitter, obtain the basic parameter data of each receiver, and perform information interaction between the basic parameter data of each receiver and the transmitter. The real-time transmitter user instruction decoding and classification sub-module is used to decode the user instructions input at the transmitter, determine whether there is a specified receiver for the currently decoded user instructions. When there is a specified receiver for the decoded user instructions, the user instruction signal is sent according to the specified receiver. When there is no specified receiver for the decoded user instructions, the category of the currently decoded user instruction signal is determined, classified according to different signal categories, and the category of the user instruction signal is sent to the unspecified receiver analysis and selection module.

[0011] By adopting the above technical solution: the non-designated receiver analysis and selection module includes a user instruction and receiver performance intersection analysis sub-module and a different receiver historical signal transmission performance analysis sub-module. The user instruction and receiver performance intersection analysis sub-module is used to match the receivers that can process the current user instruction signal category, mark the matched receivers, count the marked receivers, and send them to the different receiver historical signal transmission performance analysis sub-module.

Among them, the signal reception performance monitoring includes monitoring the receiver sensitivity, the distance between the receiver and the transmitter, the peripheral interference rate of the receiver, and the signal error rate of the receiver, and analyzing the current receiver signal reception performance index according to the monitoring data of the different marked receivers.

[0012] By adopting the above technical solution: the different receiver historical signal transmission performance analysis sub-module monitors the receiver sensitivity, the distance between the receiver and the transmitter, the peripheral interference rate of the receiver, and the signal error rate of the receiver, and sets the historical reception data sensitivity of the different currently marked receivers as M1%, M2%, M3%, …, M n-1 %, M n %, the peripheral interference rate of the receiver is N1%, N2%, N3%, …, N n-1 %, N n %, the signal error rate of the receiver is K1%, K2%, K3%, …, K n-1 %, K n %, the distance between the receiver and the transmitter is L1, L2, L3, …, L n-1 , L n , and it is set that the distance between the receiver and the transmitter is within 0 - 1 km, the influence rate of the distance on the data transmitted by the transmitter is C1%, the distance between the receiver and the transmitter is within 1 - 2 km, the influence rate of the distance on the data transmitted by the transmitter is C2%, the distance between the receiver and the transmitter is within 2 - 3 km, the influence rate of the distance on the data transmitted by the transmitter is C3%. When the distance between the receiver and the transmitter is greater than or equal to 3 km, the current receiver is refused to be connected. It is set that the integrity of the data transmitted by the transmitter historically accessed by a certain receiver is F. Among them, according to the complete coefficient of the data signal within the interval [1, 100], the historical comprehensive performance index of the current receiver is set as U. According to the formula:

[0013]

[0014] Calculate the historical comprehensive performance index of the different currently marked receivers, sort the historical comprehensive performance indexes of the different marked receivers in descending order, select from the sorted list from high to low according to the specified number of receivers to be accessed, and send the selected receivers to the different receiver transmission time limit adaptation module.

When the input user instruction does not specify a reception time limit, sort the times when the receivers receive the analog data signal, and select the receivers for reception from high to low according to the sorted list. When the input user instruction specifies a reception time limit, set the specified reception time limit as Tg. Among them, the reception time limit fluctuates by R% up and down from the current specified reception time limit. Set the specified reception time limit for the current receiver as:

The historical signal transmission performance analysis sub-module for different receivers monitors the receiver sensitivity, the distance between the receiver and the transmitter, the peripheral interference rate of the receiver, and the signal error rate of the receiver. Set the sensitivity of the historical received data of a certain receiver marked currently to 97%, the peripheral interference rate of the receiver to 6.1%, the signal error rate of the receiver to 3.2%, and the distance between the receiver and the transmitter to 1.7 km. Set that the distance between the receiver and the transmitter is within 1 - 2 km, and the influence rate of the distance on the data transmitted by the transmitter is 3%. Set the integrity of the data transmitted by the transmitter historically accessed by a certain receiver to 96, and set the historical comprehensive performance index of the current receiver to U.

[0067] 1km ≤ 1.7km < 2km

[0068] U = 96 * 97% * (1 - 6.1%) * (1 - 3.2%) * (1 - 3%) ≈ 82.1%

Set the sensitivity of the historical received data of a certain receiver marked currently to 89%, the peripheral interference rate of the receiver to 4%, the signal error rate of the receiver to 4.7%, and the distance between the receiver and the transmitter to 0.6 km. Set that the distance between the receiver and the transmitter is within 0 - 1 km, and the influence rate of the distance on the data transmitted by the transmitter is 1.7%. Set the integrity of the data transmitted by the transmitter historically accessed by a certain receiver to 93, and set the historical comprehensive performance index of the current receiver to U. According to the formula:

[0071] 0km ≤ 0.6km < 1km

[0072] U = 93 * 89% * (1 - 4%) * (1 - 4.7%) * (1 - 1.7%) ≈ 74.4%

[0073] It is calculated that the historical comprehensive performance index of the different receivers marked currently is 74.4%.
