As shown in fig. 1 and 2, in order to ensure timeliness and stability of wireless communication, the present embodiment implements data transmission in two ways, namely, direct data transmission between a signal acquisition and transmission end and a data receiving platform, and data acquisition and transmission of the signal acquisition and transmission end is forwarded to the data receiving platform through a plurality of wireless repeaters for data transmission, where the direct data transmission has a shorter delay and a higher timeliness, and is suitable for use in a scene without environmental interference, and the wireless repeaters have a longer delay and a higher stability, and are suitable for use in a scene with outdoor weather changes.
Wherein the multifunctional electronic system for wireless communication comprises: the system comprises a signal acquisition transmitting terminal 1, a data receiving platform 2, a plurality of wireless repeaters 3, a topological network data transmission system 4 and an acquisition point positioning system 5.
The signal acquisition transmitting terminal 1 is used for acquiring data; the data receiving platform 2 is used for receiving the collected data sent by the signal collecting and transmitting terminal 1 in a wireless communication mode.
The signal acquisition transmitting terminal 1 is internally provided with a wireless communication module, the same data receiving platform 2 is internally provided with a wireless communication module, the signal acquisition transmitting terminal 1 and the data receiving platform 2 directly transmit data through the wireless communication module, and it needs to be added to explain that the wireless communication module of the embodiment can be selected from a Zigbee communication mode, a WiFi communication mode or a local area network communication mode.
The plurality of wireless repeaters 3 are respectively and sequentially arranged between the signal acquisition transmitting terminal 1 and the data receiving platform 2, and are used for transmitting the acquisition data transmitted by the signal acquisition transmitting terminal 1 to the data receiving platform 2 through the plurality of wireless repeaters 3 and transmitting the acquisition data to the data receiving platform 2 in a wireless communication mode.
The topology network data transmission system 4 is disposed in the data receiving platform 2 and is used for establishing a data transmission line among the plurality of wireless repeaters 3.
The acquisition point positioning system 5 is installed in the signal acquisition transmitting terminal 1 and used for determining the acquisition position of the signal acquisition transmitting terminal 1.
The data receiving platform 2 determines the actual position of the signal acquisition transmitting terminal 1 through the acquisition point positioning system 5, the data receiving platform 2 selects the wireless repeater 3 as the communication starting point according to the actual position, the wireless repeater 3 participating in wireless communication is determined according to the topology network data transmission system 4 to form a data transmission line, and the acquired data of the signal acquisition transmitting terminal 1 is transmitted to the data receiving platform 2 through multi-stage transshipment.
Therefore, the mode of the data receiving platform 2 for receiving the transmission data of the signal acquisition transmitting terminal 1 is divided into two data transmission modes, namely a direct wireless communication transmission mode and a data forwarding wireless communication mode; the communication duration of the direct wireless communication transmission mode is shorter than the communication duration of the data forwarding wireless communication mode.
When the data receiving platform 2 selects the direct wireless communication transmission mode, the wireless communication function of the wireless repeater 3 is suspended, and the port in direct wireless communication with the signal acquisition transmitting terminal 1 is started, and when the data receiving platform 2 selects the data forwarding wireless communication mode, the wireless communication function of the wireless repeater 3 is started, the port in wireless communication with the wireless repeater 3 is started, and the port in direct wireless communication with the signal acquisition transmitting terminal 1 is closed.
The data conversion selection of the direct wireless communication transmission mode and the data forwarding wireless communication mode is mainly determined by a comparison result of the communication time length of the direct wireless communication transmission mode and the communication time length of the data forwarding wireless communication mode, when the communication time length of the direct wireless communication transmission mode exceeds the communication time length of the selected data forwarding wireless communication mode, the data forwarding wireless communication mode needs to be converted for the stability and timeliness of communication, and the specific implementation principle is as follows:
the data receiving platform 2 is internally provided with a direct communication time calculating unit 21 and a data forwarding communication time calculating unit 22, and the direct communication time calculating unit 21 calculates the communication time of the direct wireless communication transmission mode according to the sending time point of the acquired data sent by the signal acquisition and transmission terminal 1 and the receiving time point of the acquired data actually received by the data receiving platform 2.
The data forwarding communication time calculation unit 22 determines the position of the signal acquisition transmitting terminal 1 according to the acquisition point positioning system 5, determines the number of the wireless repeaters 3 constituting the data transmission line of the data forwarding wireless communication mode, and calculates the communication time length of the data forwarding wireless communication mode according to the number of the wireless repeaters 3, wherein the communication time length of the data forwarding wireless communication mode is positively correlated with the number of the wireless repeaters 3 in use, and the communication time length of the data forwarding wireless communication mode is longer as the number of the wireless repeaters 3 in use is larger.
When the communication duration of the direct wireless communication transmission mode is longer than that of the data forwarding wireless communication mode, the data receiving platform 2 converts the direct wireless communication transmission mode into the data forwarding wireless communication mode.
Of course, the communication duration of the direct wireless communication transmission mode calculated by the direct communication time calculation unit 21 has a certain delay, and when sudden severe weather occurs, the direct communication time calculation unit 21 can calculate the communication duration of the direct wireless communication transmission mode only after completing direct wireless communication once, which may cause data loss and communication failure, and thus, the calculation mode of the direct communication time calculation unit 21 has a great passivity.
As is well known, the quality of outdoor wireless communication is affected by weather, electromagnetic waves of the wireless communication can only be transmitted in a straight line basically, diffraction phenomena are weak, the absorption and scattering effects of rain and fog on the radio waves are large, the attenuation of the rain is mainly due to the scattering and absorption effects of the radio waves caused by rain, the absorption on the radio waves in the fog plays a major role in comparison with the scattering, and therefore, the direct communication between the signal acquisition transmitting terminal 1 and the data receiving platform 2 is easily affected by the environment.
The data forwarding wireless communication mode composed of the plurality of wireless repeaters 3 is equivalent to a signal transfer station between the signal acquisition transmitting terminal 1 and the data receiving platform 2, and can shorten the communication distances between the signal acquisition transmitting terminal 1 and the wireless repeaters 3, between the wireless repeaters 3 and the wireless repeaters 3, and between the wireless repeaters 3 and the data receiving platform 2, thereby ensuring the stability of data transmission and ensuring that data is not lost.
Therefore, the data receiving platform 2 collects the collection environment factors of the signal collection transmitting terminal 1 in real time, and converts the data forwarding wireless communication mode into the direct wireless communication transmission mode according to the collection environment factors, wherein the collection environment factors include wind power and rainfall.
An environment analysis model is arranged in the data receiving platform 2 and used for determining the corresponding relation between the communication time of the direct wireless communication transmission mode and the collection environment factors.
The data receiving platform 2 compares the communication time of the direct wireless communication transmission mode calculated by the direct communication time calculating unit 21 with the time delay communication time calculated by the environment analysis model to correct the environment analysis model until the communication time of the direct wireless communication transmission mode is the same as the time delay communication time calculated by the environment analysis model.
Therefore, the corrected environment analysis model can determine the time delay communication time length of the direct wireless communication transmission mode according to the current collection environment factors, and when the time delay communication time length calculated by the environment analysis model is longer than the communication time length of the data forwarding wireless communication mode, the direct wireless communication transmission mode is timely converted into the data forwarding wireless communication mode.
The budget transmission duration of the direct wireless communication transmission mode is calculated in real time by adopting the real-time environment analysis model, and the communication mode conversion between the direct wireless communication transmission mode and the data forwarding wireless communication mode can be performed in time, so that the timeliness of data transmission of wireless communication is ensured, and meanwhile, the stability of data transmission can be ensured.
Similarly, when the delay communication time of the signal acquisition transmitting terminal 1 is shorter than the communication time of the data forwarding wireless communication mode, the data receiving platform 2 switches to the direct wireless communication transmission mode for data transmission, and when the delay communication time of the signal acquisition transmitting terminal 1 is longer than the communication time of the data forwarding wireless communication mode, the data receiving platform 2 switches to the data forwarding wireless communication mode for data transmission.
It should be particularly noted that, the conversion from the direct wireless communication transmission mode to the data forwarding wireless communication mode needs to be performed under the condition that the wireless repeater 3 exists between the signal acquisition transmitting terminal 1 and the data receiving platform 2, if the distance between the signal acquisition transmitting terminal 1 and the data receiving platform 2 is smaller than the distance between the wireless repeater 3 and the data receiving platform 2, the mode conversion is not needed, and the timeliness and stability of the data transmission after the data forwarding wireless communication mode is converted are lower than those of the direct wireless communication transmission mode.
Namely, the data receiving platform 2 determines the position of the signal acquisition transmitting terminal 1 according to the acquisition point positioning system 5, and converts the direct wireless communication transmission mode according to the position of the signal acquisition transmitting terminal 1, the data receiving platform 2 compares the position of the signal acquisition transmitting terminal 1 with the position of the wireless repeater 3 closest to the data receiving platform 2, and when the position of the signal acquisition transmitting terminal 1 is smaller than the position of the wireless repeater 3 closest to the data receiving platform 2, the data receiving platform 2 still uses the direct wireless communication transmission mode.
The data receiving platform is further provided with a data correction unit, the data correction unit is used for correcting the received transmission data of the signal acquisition transmitting terminal 1 so as to eliminate interference of an acquisition environment, the data correction unit comprises a corrector determining unit and an online correction unit, the corrector determining unit is used for determining an environment interference correction function of the transmission data, and the online correction unit is used for correcting the environment interference of the transmission data so as to achieve lossless transmission from the signal acquisition transmitting terminal to the data receiving platform.
As shown in fig. 3, based on the above-mentioned structure of the multifunctional electronic system for wireless communication, the present invention provides a communication method comprising the steps of:
step 100, monitoring an acquisition environment of a signal acquisition transmitting terminal in real time, and setting up a communication scene of a direct wireless communication transmission mode and a data forwarding wireless communication mode between the signal acquisition transmitting terminal and a data receiving platform, wherein the acquisition environment is an environmental factor influencing the communication duration of the direct wireless communication transmission mode;
step 200, calculating the budget transmission time length of the direct wireless communication transmission mode according to the acquisition environment, determining the number of wireless repeaters of the data transmission line participating in the data forwarding wireless communication mode according to the position of the signal acquisition transmitting terminal, and determining the communication time length of the data forwarding wireless communication mode according to the number of the wireless repeaters;
and 300, comparing the budget transmission time length with the communication time length of the data forwarding wireless communication mode, selecting a direct wireless communication transmission mode or a data forwarding wireless communication mode according to the comparison result, and performing online correction on the transmission data by using the data correction unit.
In step 300, the online modification method for transmission data includes:
the acquisition environment may cause the transmission data to deviate in the transmission process, that is, the transmission signal received at the signal receiving platform is the signal data after the environmental interference amount is added to the transmission signal of the signal acquisition transmitting end, and in order to remove the environmental interference amount, the transmission signal received at the signal receiving platform is the same as the transmission signal at the signal acquisition transmitting end, that is, the lossless transmission between the signal acquisition transmitting end and the signal receiving platform is realized, the implementation provides an online correction method for removing the environmental interference amount, which specifically includes:

The method can realize wireless approximation of the data relationship between the test transmitting signal and the test transmission signal under the condition of sufficient data quantity of the test transmitting signal and the test transmission signal, namely, the data relationship between the test transmitting signal and the test transmission signal can be quantized into nonlinear mapping with input and output in a certain fixed form, and F is a first nonlinear mapping function body in a form of no specific mathematical expression, namely, the test transmission signal is obtained by modifying the first nonlinear mapping function body on the test transmission signal, so that the first nonlinear mapping function body F can be used for carrying out environmental interference modification on the transmission signal of the signal receiving platform to obtain modified transmission data without environmental interference, namely, the transmission signal data which is transmitted from a signal acquisition transmitting end to the signal receiving platform end in a lossless manner.
