Description

Technical Field

[0001] The present invention belongs to the technical field of lightning protection monitoring, and relates to a lightning protection monitoring system, and in particular to an intelligent lightning protection monitoring system, method, electronic equipment and storage medium. Background Art

[0002] In recent years, my country's railway construction has developed rapidly, especially the development of high-speed railways has been rapid. More and more electronic and microelectronic equipment are used in railway communication and signal equipment, which are also very susceptible to lightning strikes. Lightning protection of equipment is an important measure to protect the normal operation of electronic, microelectronic and electrical equipment. Lightning protection facilities damaged by lightning will directly affect the normal use of communication and signal equipment, interfere with the normal order of railway transportation, cause a large number of train delays, and reduce transportation efficiency.

[0003] In view of this, there is an urgent need to design a new lightning protection monitoring system to overcome at least some of the above-mentioned defects of the existing lightning protection monitoring system. Summary of the invention

[0004] The present invention provides an intelligent lightning protection monitoring system, method, electronic device and storage medium, which can greatly improve the lightning protection risk of equipment. Monitoring personnel can monitor the working status of the lightning protection ground wire and SPD at the remote control end, and can promptly discover problems in the use of lightning protection equipment.

[0005] To solve the above technical problem, according to one aspect of the present invention, the following technical solution is adopted:

[0006] An intelligent lightning protection monitoring system, the intelligent lightning protection monitoring system comprising: a server and at least one lightning protection device, the server being connected to each lightning protection device respectively;

[0007] The lightning protection device includes an intelligent monitoring host, a ground resistance monitoring module, a lightning current monitoring module, a discharge monitoring module and a degradation monitoring module; the intelligent monitoring host is connected to the ground resistance monitoring module, the lightning current monitoring module, the discharge monitoring module and the degradation monitoring module respectively;

[0008] The intelligent monitoring host is used to receive information from the ground resistance monitoring module, the lightning current monitoring module, the discharge monitoring module and the degradation monitoring module, and communicate with the server;

[0009] The grounding resistance monitoring module is used to monitor the resistance value of the grounding resistance, and send the monitored grounding resistance value to the intelligent monitoring host;

[0010] The lightning current monitoring module is used to continuously measure the current passing through the tower through a current mutual inductance coil installed at the grounding point; the normal current when there is no lightning strike, the lightning current when lightning strikes, the duration of lightning strikes, and the lightning strike time and number of lightning strikes are recorded through the entire intelligent lightning protection monitoring system;

[0011] The discharge monitoring module is connected to the current transformer to obtain the lightning current, lightning duration and number of lightning strikes at the moment of lightning strike, and send the obtained data to the intelligent monitoring host;

[0012] The degradation monitoring module is connected to the lightning arrester to obtain the status of each switch quantity of the lightning arrester and send the obtained data to the intelligent monitoring host.

[0013] As an embodiment of the present invention, the grounding resistance monitoring module is used to measure the grounding resistance; when current flows from the grounding body into the soil, resistance will appear in the soil, namely the grounding resistance; the grounding resistance includes the connection between the grounding body and the equipment, the grounding body itself and the sum of the resistance between the grounding body and the soil.

[0014] As an embodiment of the present invention, the lightning current monitoring module senses the current flowing through the ground wire by installing a current transformer on a cable connected to the ground terminal; the current is a leakage current or a lightning current; the induction ratio of the current transformer is 300A / 100ma;

[0015] The current transformer outputs current, and the circuit design allows this output to flow through the resistor R; the central processor of the intelligent monitoring host collects the voltage on the resistor R through the analog-to-digital conversion module ADC; the basic principle of analog-to-digital conversion is to convert a continuous analog signal into a discrete digital signal; this involves sampling, quantization and encoding of analog signals; sampling is to select some discrete points of the analog signal in time, and quantization is to map the values ​​of these sampling points to a limited number of digital values, and finally convert these digital values ​​into binary form through encoding; in order to make the data stable and smooth, multiple acquisitions will be performed here, removing the maximum and minimum values ​​and the average value; the average value is obtained and then converted to obtain the induced current, that is, the grounding current; the calculation process is as follows:

[0016] The voltage U across the resistor R R Calculation: By formula It turns out that: Among them, U R is the voltage value on the resistor R, U ref is the reference voltage value; AD ref is the ADC module resolution value;

[0017] Through Ohm's law formula: U = IR; we can get: Due to the mutual inductance ratio of 300A / 100ma,

[0018] As an implementation mode of the present invention, the intelligent monitoring host includes a power management module, the power management module includes a power supply voltage adjustment module, and the power supply voltage adjustment module is used to adjust the power supply voltage;

[0019] When regulating voltage, the MC34063 power chip mainly relies on some key parameters and formulas to achieve precise output voltage control; these formulas involve input voltage, output voltage, internal switch voltage drop, voltage divider resistor value, and duty cycle parameters;

[0020] For the calculation of input voltage, the formula is as follows:

[0021] Vin=Vout+Vd+(Vout*(Rdiv1+Rdiv2) / Rdiv2)

[0022] Where Vin is the input voltage, Vout is the output voltage, Vd is the internal switch voltage drop of the chip, and Rdiv1 and Rdiv2 are the resistance values ​​of the voltage divider resistors;

[0023] For the calculation of output current, the formula is:

[0024] Iout=(Vout*(1-D)) / (Rsc*D)

[0025] Where, Iout is the output current; D is the duty cycle, that is, the ratio of the switch power tube conduction time to the period; Rsc is the current detection resistor;

[0026] In addition, when MC34063 is used as an adjustable DC-DC converter, the output voltage regulation also depends on the external voltage divider resistors R1 and R2; the specific output voltage calculation formula is:

[0027] Vout=1.25*(1+(R2 / R1))

[0028] Through this formula, the appropriate resistance values ​​of R1 and R2 can be selected according to the actual output voltage required to achieve precise voltage regulation.

[0029] As an embodiment of the present invention, the intelligent monitoring host includes a data acquisition and evaluation module, the data acquisition and evaluation module includes a sine wave implementation module, and the sine wave implementation module is used to generate a sine wave;

[0030] The analog converter DAC converts digital signals into analog signals; it outputs the corresponding analog voltage or current according to the input digital code value; to achieve the output of sine wave, it needs to combine external circuits and programming control;

[0031] The process of outputting a sine wave includes:

[0032] Generate digital samples of the sine wave: First, a digital sample of the sine wave needs to be generated. This can be done in a number of ways, using a lookup table (LUT) or in real time. The lookup table method is usually faster but requires more storage space. Real time calculation can generate samples dynamically when needed, but may be limited by the speed of the processor.

[0033] Programming the DAC: Use the appropriate programming interface to transfer digital samples to the MAX531 analog converter. Write code based on the MAX531 data sheet to properly set the DAC inputs and trigger conversions.

[0034] External filtering: Since the DAC output is stepped, you need a low-pass filter to smooth the output and make it closer to a sine wave. The design of the filter depends on the required sine wave frequency and accuracy.

[0035] Adjusting amplitude and offset: By adjusting the amplitude and offset of the digital samples input to the DAC, the amplitude and DC bias of the output sine wave are controlled;

[0036] Synchronization and clock: If the frequency of the sine wave needs to be precisely controlled, an external clock or synchronization signal is used to drive the DAC conversion process;

[0037] Test and calibrate: After completing the above steps, test the output to ensure that it meets your sine wave requirements; adjust the filter design or digital sample generation method as needed to optimize performance.

[0038] As an implementation mode of the present invention, the lightning current monitoring module is used to detect lightning data; the sensor is installed in the area to be monitored, and is used to perceive the surrounding environment in real time. The sensor transmits the collected lightning data to the data processing unit; the data processing unit processes and analyzes the received data, and adopts the standardized calculation formula as follows:

[0039]

[0040] Among them, μ is the mean of the current data, and σ is the standard deviation of the current data; then the difference between each data point and the total mean is squared and summed to calculate the standard deviation. According to the standard deviation, the data is divided into several groups and the second highest mean is found. Then the lightning current intensity is classified according to the obtained current. The classification formula is as follows:

[0041]

[0042] In this way, a more accurate instantaneous lightning current can be obtained, and the obtained lightning current can be displayed in real time and summarized and analyzed by statistics and big data;

[0043] The ground resistance monitoring module is used to fit the data based on the least squares method using a cubic polynomial to smooth a set of data to reduce noise and fluctuations in the data; for a data point (y_i) ((Ix = -2, -1, 0, 1, 2)), a cubic polynomial (ly = ax^3 + bx^2 + cx + d) can be used to fit these five points; where (lx) is the position of the data point and (ly) is the corresponding data value; for the two end points of the data sequence, since it is impossible to find enough adjacent points for smoothing, other methods may need to be used for special processing, such as using boundary conditions or reducing the number of smoothing points;

[0044] The intelligent monitoring host includes a lightning arrester alarm module, and the lightning arrester alarm module is used to issue an alarm message;

[0045] The lightning arrester is used to protect electrical and electronic equipment when struck by lightning. It contains multiple lightning protection units. The lightning arrester can identify the power lightning protection box and lightning distribution cabinet based on the monitored data and send out alarm signals of different levels. The lightning arrester data is grouped into FLQ[8]. The conversion formula corresponding to each group of data is:

[0046] When FLQ>0, calculate the remainder of FLQ divided by 2: remainder = FLQ mod 2. Add remainder to the beginning of the string RS; update FLQ to the quotient of FLQ divided by 2: If FLQ becomes 0, stop the loop;

[0047] Get the status of multiple groups of lightning arresters or distribution cabinets; according to the parameters set by the system, you can get the status of the lightning protection box or lightning protection distribution cabinet of the power supply.

[0098] The present invention discloses an intelligent lightning protection monitoring system. Figure 1 This is a schematic diagram of the composition of an intelligent lightning protection monitoring system in one embodiment of the present invention; please refer to Figure 1 The intelligent lightning protection monitoring system includes: a server 2 and at least one lightning protection device 1, and the server 2 is respectively connected to each lightning protection device 1. The lightning protection device 1 includes an intelligent monitoring host 11, a grounding resistance monitoring module 12, a lightning current monitoring module 13, a discharge monitoring module 14 and a degradation monitoring module 15; the intelligent monitoring host 11 is respectively connected to the grounding resistance monitoring module 12, the lightning current monitoring module 13, the discharge monitoring module 14 and the degradation monitoring module 15.

[0099] The intelligent monitoring host 11 is used to receive information from the grounding resistance monitoring module 12, the lightning current monitoring module 13, the discharge monitoring module 14 and the degradation monitoring module 15, and communicate with the server 2. The grounding resistance monitoring module 12 is used to monitor the resistance value of the grounding resistance, and send the monitored grounding resistance value to the intelligent monitoring host.

[0100] The lightning current monitoring module 13 is used to continuously measure the current passing through this place through the current mutual inductance coil installed at the grounding point of the iron tower; by monitoring this current, the normal current when there is no lightning strike, the lightning current when the lightning strike occurs, the lightning strike duration, and the lightning strike time and number of lightning strikes are counted through the entire intelligent lightning protection monitoring system. The discharge monitoring module 14 is connected to the current transformer to obtain the lightning current, lightning strike duration and number of lightning strikes at the moment of lightning strike, and send the obtained data to the intelligent monitoring host. The degradation monitoring module 15 is connected to the lightning arrester 3 to obtain the status of each switch quantity of the lightning arrester 3, and send the obtained data to the intelligent monitoring host.

[0101] In one embodiment of the present invention, when the grounding resistance monitoring module 12 is monitoring the grounding resistance, when current flows from the grounding body into the soil, resistance will appear in the soil, namely, the grounding resistance; the grounding resistance includes the connection between the grounding body and the equipment, the grounding body itself, and the sum of the resistance between the grounding body and the soil.

[0102] If the resistance of the connection is ignored (the resistance of the connection is very small and can be ignored), the expression of the grounding resistance can be obtained as follows:

[0103]

[0104] In formula (1), R jd is the grounding resistance; p is the soil resistivity; R0 is the radius of the imaginary metal hemisphere;

[0105] Generally, the grounding device is required to have a small grounding resistance, and after laying, it is measured at a certain period. Principle wiring for measuring grounding resistance. The grounding body is replaced by an imaginary hemisphere, and the existence of electrodes 2-3 is ignored. Assuming that a current I flows into the earth through the power electrode 1, the current density on the sphere at a distance x from the center of the electrode is:

[0106]

[0107] Where j(x) is the current density on the spherical surface at a distance x from the center of the sphere; I is the current flowing into the ground through the hemisphere; x is the distance from the spherical surface to the center of the sphere;

[0108] Assuming the resistivity of the soil is ρ, the electric field strength on the spherical surface at a distance X from the center of the sphere is

[0109] E(x)=j(x)ρ

[0110] Because the potential difference between any two points in the electric field is equal to the line integral of the electric field strength between the two points, assuming that the potential at infinity is zero, the potential at a distance x (x ≥ r) from the center of the sphere is:

[0111]

[0112] The distance between the electrode 2 and the center of the sphere is X = d 12 , so the potential difference between the two is:

[0113]

[0114] Where R0 is the radius of the hemispherical electrode.

[0115] Now ignore the existence of hemispherical electrode 1, assume that electrode 3 is an ideal hemispherical electrode, and current I flows out of the earth from electrode 3. Similar to the above analysis, the potential difference generated by electrode 3 between 1 and 2 is:

[0116]

[0117] In fact, the current in the soil is the superposition of the current fields formed by the two ideal hemispherical electrodes 1 and 3, so the potential difference between electrodes 1 and 2 can be expressed as:

[0118]

[0119] From formula (1), we can know that the grounding resistance of grounding body 1 is If the formula (6) Then we have:

[0120]

[0121] Right now

[0122] Let d 12 =ad 13 , then d 23 =(1-a)d 13 ,Depend on have to:

[0123]

[0124] It can be seen that if electrode 3 is not at infinity, electrode 2 only needs to be placed between electrodes 1 and 3, 0.618d away from the ground body. 13 The grounding resistance can be accurately calculated by equation (8); this is the basic principle of the 0.618 method or compensation method.

[0125] In one embodiment of the present invention, the lightning current monitoring module 13 senses the current flowing through the ground wire by installing a current transformer on the cable connected to the ground terminal; the current is leakage current or lightning current; the induction ratio of the current transformer is 300A / 100ma. The current transformer outputs current, and the output is made to flow through the resistor R through the circuit design; the central processing unit of the intelligent monitoring host collects the voltage on the resistor R through the analog-to-digital conversion module ADC; the basic principle of analog-to-digital conversion is to convert continuous analog signals (such as voltage, temperature, etc.) into discrete digital signals; this involves sampling, quantization and encoding of analog signals; sampling is to select some discrete points of the analog signal in time, and quantization is to map the values ​​of these sampling points to limited digital values, and finally convert these digital values ​​into binary form through encoding; in order to make the data stable and smooth, multiple acquisitions will be performed here, and the maximum and minimum values ​​will be removed and the average value will be removed; the average value is obtained and then the induced current, that is, the ground wire current size, can be obtained by conversion; the calculation process is as follows:

[0126] The voltage U across the resistor R R Calculation: By formula It turns out that: Among them, U R is the voltage value on the resistor R, U ref is the reference voltage value; AD ref is the ADC module resolution value;

[0127] Through Ohm's law formula: U = IR; we can get: Due to the mutual inductance ratio of 300A / 100ma,

[0128] In one embodiment of the present invention, the intelligent monitoring host includes a power management module, and the power management module includes a power voltage regulation module, and the power voltage regulation module is used to regulate the power voltage.

[0129] When regulating voltage, the MC34063 power chip mainly relies on some key parameters and formulas to achieve precise output voltage control; these formulas involve input voltage, output voltage, internal switch voltage drop, voltage divider resistor value, and duty cycle parameters;

[0130] For the calculation of input voltage, the formula is as follows:

[0131] Vin=Vout+Vd+(Vout*(Rdiv1+Rdiv2) / Rdiv2)

[0132] Where Vin is the input voltage, Vout is the output voltage, Vd is the internal switch voltage drop of the chip, which is generally 1.5V; Rdiv1 and Rdiv2 are the resistance values ​​of the voltage divider resistors;

[0133] For the calculation of output current, the formula is:

[0134] Iout=(Vout*(1-D)) / (Rsc*D)

[0135] Where, Iout is the output current; D is the duty cycle, that is, the ratio of the switch power tube conduction time to the period (percentage); Rsc is the current detection resistor;

[0136] In addition, when MC34063 is used as an adjustable DC-DC converter, the output voltage regulation also depends on the external voltage divider resistors R1 and R2; the specific output voltage calculation formula is:

[0137] Vout=1.25*(1+(R2 / R1))

[0138] Through this formula, the appropriate resistance values ​​of R1 and R2 can be selected according to the actual output voltage required to achieve precise voltage regulation.

[0139] In one embodiment of the present invention, the intelligent monitoring host includes a data acquisition and evaluation module, and the data acquisition and evaluation module includes a sine wave implementation module, and the sine wave implementation module is used to generate a sine wave.

[0140] The analog converter DAC converts digital signals into analog signals; it outputs the corresponding analog voltage or current according to the input digital code value; to achieve the output sine wave, it needs to be combined with external circuits and programming control.

[0141] The process of the sine wave realization module outputting a sine wave includes:

[0142] Generate digital samples of the sine wave: First, a digital sample of the sine wave needs to be generated. This can be done in a number of ways, using a lookup table (LUT) or in real time. The lookup table method is usually faster but requires more storage space. Real time calculation can generate samples dynamically when needed, but may be limited by the speed of the processor.

[0143] Programming the DAC: Use the appropriate programming interface to transfer digital samples to the MAX531 analog converter. Write code based on the MAX531 data sheet to properly set the DAC inputs and trigger conversions.

[0144] External filtering: Since the DAC output is stepped, you need a low-pass filter to smooth the output and make it closer to a sine wave. The design of the filter depends on the required sine wave frequency and accuracy.

[0145] Adjusting amplitude and offset: By adjusting the amplitude and offset of the digital samples input to the DAC, the amplitude and DC bias of the output sine wave are controlled;

[0146] Synchronization and clock: If the frequency of the sine wave needs to be precisely controlled, an external clock or synchronization signal is used to drive the DAC conversion process;

[0147] Test and calibrate: After completing the above steps, test the output to ensure that it meets your sine wave requirements; adjust the filter design or digital sample generation method as needed to optimize performance.

[0148] In one embodiment of the present invention, the lightning current monitoring module is used to detect lightning data; the sensor is installed in the area to be monitored, and is used to sense the surrounding environment in real time. The sensor transmits the collected lightning data to the data processing unit; the data processing unit processes and analyzes the received data, and adopts the standardized calculation formula as follows:

[0149]

[0150] Among them, μ is the mean of the current data, and σ is the standard deviation of the current data; then the difference between each data point and the total mean is squared and summed to calculate the standard deviation. According to the standard deviation, the data is divided into several groups and the second highest mean is found. Then the lightning current intensity is classified according to the obtained current. The classification formula is as follows:

[0151]

[0152] In this way, a more accurate instantaneous lightning current can be obtained, and the obtained lightning current can be displayed in real time and summarized and analyzed by statistics and big data;

[0153] The measurement and alarm function of auxiliary resistance is crucial to ensure the safety and performance of the grounding system, and improves the measurement accuracy and system reliability. The grounding resistance monitoring module is used to fit the data based on the least squares method using a cubic polynomial to smooth a set of data to reduce noise and fluctuations in the data; for the data point (y_i) ((Ix=-2,-1,0,1,2)), a cubic polynomial (ly=ax^3+bx^2+cx+d) can be used to fit these five points; where (lx) is the position of the data point, and (ly) is the corresponding data value; for the two endpoints of the data sequence, since it is impossible to find enough adjacent points for smoothing, other methods may need to be used for special processing, such as using boundary conditions or reducing the number of smoothing points;

[0154] According to the principle of least squares method, the measured grounding resistance data is statistically analyzed to understand the concentration trend and discreteness of the data. The abnormal data can also be analyzed to obtain the following alarm contents: the interference signal is too large; the auxiliary current pole resistance is too large or disconnected; the grounding resistance pole resistance is too large or disconnected; the DC component is too large; the ground resistance is greater than 150; the auxiliary voltage pole is disconnected; the auxiliary resistance value is too large.

The lightning arrester can identify the power lightning protection box and lightning protection distribution cabinet according to the monitored data, and issue different levels of alarm signals, grouping the lightning arrester data into FLQ[8]. The conversion formula corresponding to each group of data is:

[0156] When FLQ>0, calculate the remainder of FLQ divided by 2: remainder = FLQ mod 2; add remainder to the beginning of the string RS; update FLQ to the quotient of FLQ divided by 2: If FLQ becomes 0, stop the loop;

[0157] Get the status of multiple groups of lightning arresters or distribution cabinets; according to the parameters set by the system, you can get the status of the lightning protection box of the power supply or the lightning protection distribution cabinet.
