Description

Technical Field

[0001] The invention relates to the technical field of rolling shutter doors, in particular to a detection and control method and a device for an electric rolling shutter door. Background Art

[0002] At present, with the continuous development of the domestic economy, financial activities are becoming more frequent, and financial units and financial outlets are increasing day by day. How to ensure the safety of personnel, equipment and funds of various financial units is an important issue in the current financial security field. According to the physical prevention requirements of the Ministry of Public Security GA745-2017, anti-theft doors or rolling shutters should be installed at the entrances and exits connecting the customer activity area of ​​the bank-type self-service bank with other areas. The electric rolling shutter door controller does not have a corresponding detection device, and it relies entirely on the limit to open and close the rolling shutter door. It is impossible to determine whether there are objects blocking it below, and it cannot be closed or other objects or people are involved in the upward process. Accidents occur from time to time, causing objects to be crushed and rolling shutter doors to be damaged. GA38-2015 requires the installation of anti-theft locks on the basis of meeting GA745. Due to the interference of universal frequencies and the increase of the bank's own wireless equipment, the normal communication between the ground lock and the controller is affected, which further increases the failure of damaging the rolling shutter door blades, causing serious economic losses to the bank. Summary of the invention

[0003] In order to solve the problems in the above-mentioned background technology, the present invention provides a detection control method and device for an electric rolling door.

[0004] The technical solution adopted by the present invention to solve the technical problem is: an electric rolling door detection control method, by high-frequency sampling of the current value of the rolling door motor, according to the change of the motor current value, the state of the electric rolling door is detected and controlled, and the specific steps of the detection control method are as follows:

[0005] Step A: After the electric rolling door is newly installed or the control device is replaced, the rolling door is opened and closed twice. During the operation of the rolling door, the motor current is sampled at high frequency. Each sampling data is first filtered by a first-order low-pass filter and then processed by the arithmetic mean filter method to obtain a sampled current value. The current sampled current value is periodically compared with the previous sampled current value to obtain a current difference. During the process of opening and closing the rolling door twice, the maximum current difference obtained is set as the initial current change value I;

[0006] Step B: perform high-frequency sampling of the motor current during the startup period from when the motor is powered on to normal operation, and set the current value obtained by first filtering the current value sampled at the startup period with a first-order low-pass filter and then filtering it with an arithmetic mean value as the current reference value;

[0007] Step C: After the motor runs normally, the motor current is sampled at high frequency. Each sampling data is firstly processed by a first-order low-pass filter and then by an arithmetic mean filtering method to obtain a sampled current value. The first sampled current value is compared with the current reference value obtained in step B. The subsequent sampled current values ​​are periodically compared with the previous sampled current value. The current difference after each sampling comparison is set as the current current change value △I;

[0008] Step D: compare the difference between the current change value △I and the initial current change value I in step A and set it to Ia, that is, Ia=△II, and determine whether the rolling door encounters resistance during operation according to the size of the difference Ia; when the difference Ia exceeds the preset resistance current protection value, and the duration t that the difference Ia exceeds the resistance current protection value is greater than one sampling period, the rolling door encounters resistance during operation, and the motor stops running;

[0009] When the difference Ia is less than the preset resistance current protection value, it is a normal current fluctuation during the operation of the rolling door, and the motor can operate normally;

[0010] Step E: When the difference Ia is less than the preset resistance current protection value and the difference Ia is greater than the initial current change value I, the difference Ia is updated to a new initial current change value I, so as to realize the detection and control of the friction change during the aging and operation of the adaptive rolling door motor;

[0011] Step F: Each time the motor runs thereafter, steps B to E are repeated, and the initial current change value I in the difference Ia=△II is substituted into the most recently updated value I to calculate the current difference Ia.

[0012] Furthermore, the sampling frequency in steps A to C is 10 to 200 Hz, and the stability and sensitivity of the current sampling value are improved by a higher sampling frequency.

[0013] Further, in step C, when each sampling data is processed by the arithmetic mean filtering method after the first-order low-pass filtering and the sampling current value exceeds 1.2 times the rated current value of the motor, it is a motor failure or a sampling process failure; the motor is stopped to protect the motor and detect sampling errors in time.

[0014] Furthermore, the resistance current protection value in step D and step E is I+0.2A, and the resistance current protection value is set according to the motor power of the rolling door and can be used to adjust the resistance sensitivity.

[0016] The current sampling module of the current acquisition device is used to perform high-frequency sampling of the motor current. The current sampling signal is subjected to multiple smoothing and filtering processes by the first multi-order signal filtering module. The current sampling signal is then amplified by the signal amplifier. The amplified current sampling signal is then subjected to the final filtering process by the signal filtering module. The final current sampling signal is output to the analysis and processing device via the sampling signal output module.

[0017] The second multi-order signal filtering module of the analysis and processing device is used to perform a first-order low-pass filtering on the current sampling signal output by the sampling signal output module and then perform arithmetic mean filtering to meet the analysis and processing requirements. The analysis microprocessor is used to perform arithmetic mean filtering on the current sampling value and compare the defined values. The external trigger module is used to connect external devices for manual interaction such as keyboards and switch buttons. The motor control module is used to control the rolling door motor.

[0018] Further preferably, the current sampling module is provided with a constantan wire sampling resistor for motor current sampling, and the resistance of the constantan wire sampling resistor is 5mR; its maximum withstand current is not less than 20A, and the current sampling module can provide accurate and effective current sampling values.

[0019] Furthermore, the analysis microprocessor is a single chip microcomputer, which can process and calculate the current sampling value data by setting moving weighted or recursive averaging method, arithmetic averaging method, limiting method, limiting mean method, median value method and other methods.

[0020] Furthermore, the first multi-order signal filtering module and the second multi-order signal filtering module are provided with a low-pass filtering circuit to achieve smoothing filtering processing on the current sampling signal, thereby improving the stability and sensitivity of the sampling value.

[0023] The method automatically updates the initial value I within a reasonable fluctuation range during the detection process, and detects and controls the changes in friction during the aging and operation of the rolling door motor, which greatly improves the stability and sensitivity of the detection control.

[0024] The sampling frequency is 10-200HZ. The stability and sensitivity of the current sampling value are improved through a higher sampling frequency.

[0025] The preset resistance current protection value is I+0.2A. The resistance current protection value is set according to the rolling door motor power and is used to adjust the resistance sensitivity.

DETAILED DESCRIPTION

[0040] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0041] like Figure 1 As shown, a detection and control method for an electric rolling door is provided, which detects and controls the state of the electric rolling door according to the change of the motor current value by continuously sampling the current value of the rolling door motor at high frequency. Figure 3 The current variation waveform of the existing rolling shutter door is shown in FIG. Figure 4 To implement the current waveform diagram of the present invention, the specific steps of the detection control method are as follows:

[0042] Step A: After the electric rolling door is newly installed or the control device is replaced, the rolling door is opened and closed twice. During the operation of the rolling door, the motor current is sampled at high frequency. Each sampling data is first filtered by a first-order low-pass filter and then processed by the arithmetic mean filter method to obtain a sampled current value. The current sampled current value is periodically compared with the previous sampled current value to obtain a current difference. During the process of opening and closing the rolling door twice, the maximum current difference obtained is set as the initial current change value I;

[0043] Step B: perform high-frequency sampling of the motor current during the startup period from when the motor is powered on to normal operation, and set the current value obtained by first filtering the current value sampled at the startup period with a first-order low-pass filter and then filtering it with an arithmetic mean value as the current reference value;

[0044] Step C: After the motor runs normally, the motor current is sampled at high frequency. Each sampling data is firstly processed by a first-order low-pass filter and then by an arithmetic mean filtering method to obtain a sampled current value. The first sampled current value is compared with the current reference value obtained in step B. The subsequent sampled current values ​​are periodically compared with the previous sampled current value. The current difference after each sampling comparison is set as the current current change value △I;

[0045] Step D: compare the difference between the current change value △I and the initial current change value I in step A and set it to Ia, that is, Ia=△II, and determine whether the rolling door encounters resistance during operation according to the size of the difference Ia; when the difference Ia exceeds the preset resistance current protection value, and the duration t that the difference Ia exceeds the resistance current protection value is greater than one sampling period, the rolling door encounters resistance during operation, and the motor stops running;

[0046] When the difference Ia is less than the preset resistance current protection value, it is a normal current fluctuation during the operation of the rolling door, and the motor can operate normally;

[0047] Step E: When the difference Ia is less than the preset resistance current protection value and the difference Ia is greater than the initial current change value I, the difference Ia is updated to a new initial current change value I, so as to realize the detection and control of the friction change during the aging and operation of the adaptive rolling door motor;

[0048] Step F: Each time the motor runs thereafter, steps B to E are repeated, and the initial current change value I in the difference Ia=△II is substituted into the most recently updated value I to calculate the current difference Ia.

[0049] Furthermore, the sampling frequency in steps A to C is 10 to 200 Hz, and the stability and sensitivity of the current sampling value are improved by a higher sampling frequency.

[0050] Further, in step C, when each sampling data is processed by the arithmetic mean filtering method after the first-order low-pass filtering and the sampling current value exceeds 1.2 times the rated current value of the motor, it is a motor failure or a sampling process failure; the motor is stopped to protect the motor and detect sampling errors in time.

[0051] Furthermore, the resistance current protection value in step D and step E is I+0.2A, and the resistance current protection value is set according to the motor power of the rolling door and can be used to adjust the resistance sensitivity.

[0052] like Figure 2As shown, an electric rolling door detection control device includes a current acquisition device 1 and an analysis and processing device 2 connected thereto; the current acquisition device 1 includes a current sampling module 11, a first multi-order signal filtering module 12, a signal amplifier 13, a signal filtering module 14, and a sampling signal output module 15; the current sampling module 11 is connected to the input end of the signal amplifier 13 through the first multi-order signal filtering module 12, and the output end of the signal amplifier 13 is connected to the sampling signal output module 15 through the signal filtering module 14; the analysis and processing device 2 includes a second multi-order signal filtering module 21, an analysis microprocessor 22, an external trigger module 23, and a motor control module 24; the analysis microprocessor 22 is respectively connected to the second multi-order signal filtering module 21, the external trigger module 23 and the motor control module 24; the sampling signal output module 15 of the current acquisition device 1 is connected to the second multi-order signal filtering module 21 of the analysis and processing device 2.

[0053] The current sampling module 11 of the current acquisition device 1 is used to perform high-frequency sampling of the motor current. The current sampling signal is subjected to multiple smoothing filtering processes through the first multi-order signal filtering module 12. The current sampling signal is then amplified through the signal amplifier 13. The amplified current sampling signal is then subjected to a final filtering process through the signal filtering module 14. The final current sampling signal is output to the analysis and processing device 2 through the sampling signal output module 15.

[0054] The second multi-order signal filtering module 21 of the analysis and processing device 2 is used to perform a first-order low-pass filtering on the current sampling signal output by the sampling signal output module 15 and then perform arithmetic mean filtering to meet the analysis and processing requirements. The analysis microprocessor 22 is used to perform arithmetic mean filtering on the current sampling value and compare the defined values. The external trigger module 23 is used to connect to external devices for manual interaction such as keyboards and switch buttons. The motor control module 24 is used to control the rolling door motor.

[0055] The current sampling module 11 is provided with a constantan wire sampling resistor for motor current sampling. The constantan wire sampling resistor has a resistance of 5mR and a maximum withstand current of not less than 20A, which can provide the current sampling module 11 with accurate and effective current sampling values.

[0056] The analysis microprocessor 22 is a single chip microcomputer, which can process and calculate the current sampling value data by setting moving weighting, recursive averaging, arithmetic averaging, limiting method, limiting mean method, median value method and other methods.

[0057] The first multi-order signal filtering module 12 and the second multi-order signal filtering module 21 are provided with low-pass filtering circuits to achieve smooth filtering processing of the current sampling signal, improve the stability and sensitivity of the sampling value, and meet the processing operation requirements.

[0058] The signal amplifier 13, the analysis microprocessor 22 and the motor control module 24 are connected to a power supply module 3, and the power supply module 3 is used to supply power to the inside of the device.

[0059] like Figures 1-2 As shown, the implementation process of this method is further described below in combination with the electric rolling door detection control device. By continuously sampling the current value of the rolling door motor at a high frequency, the state of the electric rolling door is detected and controlled according to the change of the motor current value, such as Figure 3 The current variation waveform of the existing rolling shutter door is shown in FIG. Figure 4 To implement the current waveform diagram of the implementation process of the present invention, the specific steps of the detection and control method are as follows:

[0060] Step A: After the electric rolling door is newly installed or replaced with a control device, the rolling door is opened and closed twice. The current acquisition device 1 samples the motor current at high frequency during the operation of the rolling door. The analysis and processing device 2 first passes each sampling data through a first-order low-pass filter and then performs an arithmetic mean filtering method to obtain a sampled current value. The current sampled current value is periodically compared with the previous sampled current value to obtain a current difference. In the process of opening and closing the rolling door twice, the maximum current difference obtained is set as the initial current change value I;

[0061] Step B: the current acquisition device 1 performs high-frequency sampling of the motor current during the startup period from when the motor is powered on to normal operation, and the analysis and processing device 2 performs a first-order low-pass filtering and then arithmetic mean filtering on the current value obtained during the startup period to set the current value as the current reference value;

[0062] Step C: After the motor runs normally, the current acquisition device 1 samples the motor current at high frequency, and the analysis and processing device 2 obtains the sampled current value by first filtering each sampled data with a first-order low-pass filter and then performing arithmetic mean filtering. The first sampled current value is compared with the current reference value obtained in step B, and the subsequent sampled current values ​​are periodically compared with the previous sampled current value. The current difference after each sampling comparison is set as the current current change value △I, such as Figure 5 As shown;

[0063] Step D: The analysis and processing device 2 compares the difference between the current change value △I and the initial current change value I in step A and sets it to Ia, that is, Ia=△II, and determines whether the rolling door encounters resistance during operation according to the size of the difference Ia; when the difference Ia exceeds the preset resistance current protection value, and the duration t that the difference Ia exceeds the resistance current protection value is greater than one sampling period, it means that the rolling door encounters resistance during operation, and the motor control module 24 stops the motor operation, such as Figures 6 to 9 As shown;

[0064] When the difference Ia is less than the preset resistance current protection value, the analysis and processing device 2 determines that it is a normal current fluctuation during the operation of the rolling door, and the motor can operate normally;

[0065] Step E: When the difference Ia is less than the preset resistance current protection value and the difference Ia is greater than the initial current change value I, the analysis and processing device 2 updates the difference Ia to a new initial current change value I, thereby realizing detection and control of the friction change during the aging and operation of the adaptive rolling door motor.

[0066] Step F: Each time the motor runs thereafter, steps B to E are repeated, and the initial current change value I in the difference Ia=△II is substituted into the most recently updated value I to calculate the current difference Ia.

[0067] The sampling frequency in step A to step C is 10 to 200 Hz, and the stability and sensitivity of the current sampling value are improved by a higher sampling frequency.

[0068] In step C, when each sampling data is processed by the arithmetic mean filtering method after the first-order low-pass filtering and the sampling current value exceeds 1.2 times the rated current value of the motor, it means that the motor is faulty or the sampling process fails, and the motor is stopped to protect the motor and detect sampling errors in time.

[0069] The resistance current protection value in step D and step E is I+0.2A, and the resistance current range value is set according to the motor power of the rolling door, which is used to adjust the resistance sensitivity of the rolling door.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
