Technical Field

[0001] The present invention relates to the field of signal communication measurement and control, and in particular to a digital communication system for electronic signal measurement and control equipment. Background Art

[0002] Measurement and control technology is the process of collecting, organizing, processing, and then displaying or issuing control signals on the automation system. The key technology lies in the acquisition and processing of signals. In measurement and control technology, the form of signal transmission and the selected transmission method determine the security and accuracy of the information. In the measurement and control process, the digital communication system used for signal transmission is the top priority of the entire process. Digital communication refers to the use of digital signals as carriers for transmission, or the use of digital signals to digitally modulate the carrier and then transmit it. Its main technical equipment includes transmitters, receivers, and transmission media. When measuring and controlling electronic signals, people can communicate and transmit test signals through digital communication systems and observe in the process. However, general digital communication systems only realize the transmission and communication functions, and are relatively lacking in monitoring and anti-interference during signal transmission, which is not conducive to electronic signal measurement and control. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a digital communication system for electronic signal measurement and control equipment.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: an electronic signal measurement and control equipment digital communication system, including a measurement and control equipment communication system, the measurement and control equipment communication system including a central control console, a test signal monitoring system, a digital signal communication system, a communication debugging switching system and an abnormal interference processing system, the central control console is connected to the test signal monitoring system, the digital signal communication system, the communication debugging switching system and the abnormal interference processing system, the test signal monitoring system is connected to the digital signal communication system, the digital signal communication system is connected to the communication debugging switching system, and the communication debugging switching system is connected to the abnormal interference processing system.

[0005] Preferably, the test signal monitoring system includes an output monitoring module, a receiving monitoring module and a channel monitoring module, the output monitoring module is connected to the receiving monitoring module, and the receiving monitoring module is connected to the channel monitoring module.

[0006] Preferably, the digital signal communication system includes a digital communication module, a signal encryption module, a signal translation module and a transmission comparison module, the digital communication module is connected to the signal encryption module, the signal encryption module is connected to the signal translation module, and the signal translation module is connected to the transmission comparison module.

[0007] Preferably, the communication debugging and switching system includes a wave frequency stabilization module, a channel switching module, a wave frequency debugging module and a communication detection module, the wave frequency stabilization module is connected to the channel switching module, the channel switching module is connected to the wave frequency debugging module, and the wave frequency debugging module is connected to the communication detection module.

[0008] Preferably, the abnormal interference processing system includes an abnormality monitoring module, an interference analysis module, a corresponding adjustment module and a communication synchronization module, the abnormality monitoring module is connected to the interference analysis module, the interference analysis module is connected to the corresponding adjustment module, and the corresponding adjustment module is connected to the communication synchronization module.

[0009] Preferably, the communication detection module performs frequency debugging of signal transmission communication by using a cyclic redundancy check method; wherein the error detection process of signal transmission includes the following steps:

[0010] Let: G(x) divided by X'K(x) is Q(x), then:

[0011] X'K(x)=G(x)Q(x)+R(x)

[0012] Then we can get: T(x)=X'K(x)+R(x)=G(x)o(x)+R(x)+R(x);

[0013] Where "+" is a logical exclusive OR, and we get R(x)+R(x)=0; so we get:

[0014] T(x)=X'K(x)+R(x)=G(x)Q(x)+R(xr)+R(x)=G(x)Q(x)

[0015] Therefore, if the transmission is error-free, T(x) can be divided by G(x). If the remainder is zero, the transmission is error-free; if the remainder is not zero, the transmission is error-free.

[0016] Preferably, the calculation formula used when debugging the wave frequency debugging module is:

[0017] f(t)=f0+kt

[0018] Where f(t) indicates the signal frequency at time t, f0 represents the initial frequency, k represents the frequency modulation slope,

[0019] According to this formula, we can calculate the signal frequency at different time points. By controlling the initial frequency and the frequency modulation slope, we can achieve precise control of the signal frequency, thereby realizing efficient signal transmission and information encoding.

[0020] Preferably, the abnormality monitoring module monitors the communication quality by calculating and monitoring the signal-to-noise ratio, and the specific calculation method is as follows:

[0021] SNR=10log10(p1 / p2)

[0022] Among them, p1 is the effective signal power, p2 is the noise power, and the larger the SNR value is, the greater the effective signal power is than the noise power, and the better the system performance is.

By debugging different frequencies, the stability of signals with different frequencies and between different channels during transmission can be monitored, which is beneficial to signal measurement and control.

[0025] 2. During the frequency modulation test, the communication transmission quality can be detected through the communication detection module. During the signal transmission process, the abnormality monitoring module can be used to monitor abnormal signals in the signal. Then, the interference analysis module and the corresponding adjustment module can be used to shield and reduce the interference of the channel with corresponding intensity according to the signal-to-noise ratio calculated by the detection, which is beneficial for practical use.

The output monitoring module 121 is connected to the receiving monitoring module 122, and the receiving monitoring module 122 is connected to the channel monitoring module 123. The output monitoring module 121 can monitor the output end when the signal test equipment is working, and the receiving monitoring module 122 can monitor the signal receiving end. At the same time, the channel monitoring module 123 can monitor the signal transmission channel.

[0037] The digital signal communication system 13 includes a digital communication module 131, a signal encryption module 132, a signal translation module 133 and a transmission comparison module 134. The digital communication module 131 is connected to the signal encryption module 132, the signal encryption module 132 is connected to the signal translation module 133, and the signal translation module 133 is connected to the transmission comparison module 134. People can use the digital communication module 131 to realize signal communication transmission of signal measurement and control equipment. During transmission testing, the signal encryption module 132 can be used to encrypt digital signals, and the signal translation module 133 can be used to translate and decrypt them. Through the transmission comparison module 134, the integrity of the translated signal information can be compared with the test file, that is, the digital communication transmission channel can be preliminarily verified.

[0038] The communication debugging and switching system 14 includes a frequency stabilization module 141, a channel switching module 142, a frequency debugging module 143 and a communication detection module 144. The frequency stabilization module 141 is connected to the channel switching module 142, the channel switching module 142 is connected to the frequency debugging module 143, and the frequency debugging module 143 is connected to the communication detection module 144. During the communication test, the frequency stabilization module 141 can stabilize the frequency of the test signal, and the channel switching module 142 can switch channels according to test needs, thereby realizing the test of different signal transmission channels. At the same time, the frequency debugging module 143 can debug the frequency of the test signal, and by debugging different frequencies, the stability of the transmission between signals of different frequencies and different channels can be achieved. During the frequency modulation test, the communication detection module 144 can realize the detection of the communication transmission quality.

[0039] The abnormal interference processing system 15 includes an abnormal monitoring module 151, an interference analysis module 152, a corresponding adjustment module 153 and a communication synchronization module 154. The abnormal monitoring module 151 is connected to the interference analysis module 152, the interference analysis module 152 is connected to the corresponding adjustment module 153, and the corresponding adjustment module 153 is connected to the communication synchronization module 154. During the signal transmission process, the abnormal monitoring module 151 can monitor the abnormal signal in the signal, and then the interference analysis module 152 and the corresponding adjustment module 153 can shield and reduce the interference of the corresponding intensity of the channel according to the signal-to-noise ratio calculated by the detection, and the communication transmission process can be synchronized through the communication synchronization module 154.

[0040] The communication detection module 144 uses a cyclic redundancy check (CRC) check to debug the frequency of the signal transmission communication. The error detection process of the signal transmission includes the following steps:

[0041] Let: G(x) divided by X'K(x) is Q(x), then:

[0042] X'K(x)=G(x)Q(x)+R(x)

[0043] Then we can get: T(x)=X'K(x)+R(x)=G(x)o(x)+R(x)+R(x);

[0044] Where "+" is a logical exclusive OR, and we get R(x)+R(x)=0; so we get:

[0045] T(x)=X'K(x)+R(x)=G(x)Q(x)+R(xr)+R(x)=G(x)Q(x)

[0046] Therefore, if the transmission is error-free, T(x) can be divided by G(x). If the remainder is zero, the transmission is error-free; if the remainder is not zero, the transmission is error-free.

[0047] The calculation formula used when debugging the wave frequency debugging module 143 is:

[0048] f(t)=f0+kt

[0049] Where f(t) indicates the signal frequency at time t, f0 represents the initial frequency, k represents the frequency modulation slope,

[0050] According to this formula, we can calculate the signal frequency at different time points. By controlling the initial frequency and the frequency modulation slope, we can achieve precise control of the signal frequency, thereby realizing efficient signal transmission and information encoding.

[0051] The abnormality monitoring module 151 monitors the communication quality by calculating and monitoring the signal-to-noise ratio. The specific calculation method is as follows:

[0052] SNR=10log10(p1 / p2)

[0053] Among them, p1 is the effective signal power, p2 is the noise power, and the larger the SNR value is, the greater the effective signal power is than the noise power, and the better the system performance is.

[0054] Working principle:

[0055] In actual use, people can realize signal communication transmission of signal measurement and control equipment through the digital communication module 131, use the signal encryption module 132 to encrypt digital signals during transmission testing, and use the signal translation module 133 to translate and decrypt. Through the transmission comparison module 134, the integrity of the translated signal information can be compared with the test file, that is, the digital communication transmission channel can be preliminarily verified. Through the output monitoring module 121, the output end of the signal test equipment can be monitored when it is working, and the receiving monitoring module 122 can be used to monitor the signal receiving end. At the same time, the signal transmission channel can be monitored through the channel monitoring module 123. During communication testing, the frequency of the test signal can be stabilized through the frequency stabilization module 141. The channel switching module 142 can switch channels according to test needs, thereby realizing the test of different signal transmission channels. At the same time, the frequency debugging module 143 can debug the frequency of the test signal. By debugging different frequencies, the stability of signals of different frequencies and different channels during transmission can be achieved. During the frequency modulation test, the communication detection module 144 can detect the communication transmission quality. During the signal transmission process, the abnormality monitoring module 151 can monitor the abnormal signals in the signal. Afterwards, the interference analysis module 152 and the corresponding adjustment module 153 can shield and reduce the interference of the corresponding intensity of the channel according to the signal-to-noise ratio calculated by the detection. The communication synchronization module 154 can synchronize the communication transmission process.
