The acceleration sensor LSM6DS3TR sends the information of the acceleration direction and the angular rate direction detected at this moment to the main control chip R818 through the communication protocol established by the I2C communication interface.
As shown in fig. 4, a schematic diagram of a person detection flow of a card reader device with an anti-theft function is provided, and the method is applicable to the card reader device shown in fig. 1 or 2, and specifically may include:
step one, an infrared emitting diode receives signals through an input/output I/O port. Specifically, a main control chip R818 arranged in the face card machine is connected with the infrared emitting diode HMIRA55T through a main control PWM port (I/O port), the main control chip R818 is connected with the infrared receiving head SNM437 through a main control RX port (I/O port), and the main control chip R818 continuously emits a pulse signal with a certain frequency to the infrared emitting diode through a pulse width modulation PWM port.
And step two, the infrared emitting diode emits pulse signals with fixed frequency, wherein the infrared emitting diode receives the signals sent by the main control chip and converts the signals into infrared signals which can be identified by the infrared receiving head to send.
And step three, judging the direction of the person approaching the card machine through the infrared signal received by the infrared receiving head. When the person is detected to approach the card machine from the front side in the infrared mode, the person reflects an infrared emission signal to the front side receiving head; if no person approaches the card machine in any direction, the card machine is positioned on a screen saver interface and does not give an alarm; when the infrared detection personnel get close to the card machine from the side, the personnel reflect the infrared signal to the side receiving head.
Wherein, under the condition that infrared detection is carried out to the personnel approaching the card machine from the front and the personnel reflect the infrared emission signal to the front receiving head, the method can also comprise the following steps:
and step 1, receiving the reflected infrared signal by an infrared receiving head. Specifically, the main control chip continuously transmits a pulse signal with a certain frequency to the infrared emitting diode through the PWM port, and the infrared emitting diode receives the signal and converts the signal into an infrared signal which can be identified by the infrared receiving head; the infrared receiving head receives the reflected infrared signal. That is, when a person approaches the card from the front or the side, the person is detected by the front infrared emitting device and reflected back to the receiving head SNM437 by the infrared signal.
Step 2: the main control chip calculates the actual distance S1 between the personnel and the card machine through S =1/2 VT. Specifically, the receiving head transmits the received infrared signal to the main control chip, and the main control chip measures the horizontal distance S of a person in front of the card machine by using the infrared distance measurement principle, so that the horizontal position coordinate information S1 of one person can be obtained. Wherein, general card machine will set up an image frame at the screen interface of punching the card for correct personnel punch the card distance d1 (the people stands in the card machine in front to the horizontal distance of card machine), personnel only align the edge of face with the image frame, just can carry out the operation of punching the card of people's face, if will force to dismantle the card machine, personnel must be close to the card machine, then the distance to the card machine this moment must be less than d1, the horizontal distance of side personnel to the card machine also can have a safe threshold value d2.
And step 3: the interval is 0.5S, and the main control chip obtains the actual distance S2 of the card machine through S =1/2VT calculation personnel. Specifically, when the infrared emitting diodes and the infrared receiving heads which are positioned above and on the side face of the screen detect that a person approaches the card machine for the first time and the distance coordinate is S1, the infrared emitting diodes which are positioned on the front face at the interval of 0.5S perform infrared distance measurement again to obtain the distance coordinate information S2 of the person.
And 4, step 4: and the distance is 0.5S, and the main control chip calculates the actual distance S3 from the personnel to the card machine through S =1/2 VT. Specifically, the infrared emitting diode on the front side continuously emits pulse signals with fixed frequency, the infrared receiving head converts the received infrared signals into electric signals which can be identified by the chip, and the main control chip R818 calculates to obtain the coordinate information S3 of the position of the person at the moment by using the infrared distance measuring principle.
And 5: the average value of the three ranges & S1= (S1 + S2+ S3)/3 is calculated, and it is determined whether it is within the set threshold d1, that is, & S1< d1. Specifically, an average value of three times of equal interval time ranging is calculated as a final person distance position coordinate, an average value of the three times of ranging & S1= (S1 + S2+ S3)/3 can be obtained by using an average value calculation formula, the final person distance position coordinate obtained by infrared ranging is compared with a card machine front distance d1 set by a main control chip R818, if & S1< d1, it is indicated that the current person distance from the card machine is in an abnormal state, but it is not excluded that the person distance position acquisition and judgment of the first to fifth steps are continued because the position of an careless station is too close to the card machine when the person performs the card punching operation.
Step 6: and (5) circulating three times to obtain and judge the distance positions of the personnel from the first step to the fifth step. If the average values of the three distance measurements obtained at the moment are all & S1< d1, the fact that the distance between the person and the position coordinate is too close to be smaller than the set threshold value d1 can be judged.
And 7: and a timer arranged in the main control chip is used for timing, and whether the stay time of the personnel is within the time threshold range or not is judged (the stay time of the personnel in the card machine is not too long, and the personnel is judged to be abnormally close to the card machine if the stay time is too long).
And step 8: and determining that the approach of the personnel is abnormal approach based on the fact that the stay time of the personnel is within the time threshold range, and starting the gyroscope to judge the attitude angle.
And step 9: and judging that the attitude angle &2 of the card machine is greater than the set threshold value &1 of the system at the moment.
When a person approaches the card machine from the front or the side of the screen of the card machine, the card machine is forcibly detached, and at the moment, because the fixed installation position of the card machine is changed, the built-in gyroscope LSM6DS3TR can also trigger the attitude angle (acceleration and angular rate) detection of the gyroscope along with the change of the installation position of the card machine, and a normal threshold range &1 of the attitude angle can be set through the main control R818. If the attitude angle detected by the gyroscope is within the range of the threshold value &1, the response of the gyroscope LSM6DS3TR is not triggered; if the gyroscope is installed outdoors and the attitude angle of the gyroscope is changed by changing the position of the card machine due to wind and other inefficacy factors and the change &2< &1 & gt of the attitude angle of the gyroscope is caused, the gyroscope does not report the attitude angle information to the main control chip R818 at the moment; if the person forcibly carries out the violent disassembly, the posture angle detected by the gyroscope is &2> &1, and at the moment, the gyroscope sends the detected abnormal posture angle information to the main control chip R818 through a communication protocol.
Step 10: and transmitting the alarm signal to the mobile phone server through Wi-Fi.
The main control chip reports to the server through a WIFI communication interface of the storage card SDMMC, and the WIFI module WF-R189-SSH1 transmits signals to the mobile phone server, so that alarm is triggered. Optionally, the red RGB indicator light of the card machine is always on for warning.
Step 11: the mobile phone server receives the signal and sends out an alarm prompt.
Wherein, under the condition that infrared detection detects that personnel approaches the card machine from the side surface and the personnel reflect infrared signals to the side surface receiving head, the method can also comprise the following steps:
and step 1, receiving the reflected infrared signal by an infrared receiving head. Specifically, the main control chip continuously transmits a pulse signal with a certain frequency to the infrared emitting diode through the PWM port, and the infrared emitting diode receives the signal and converts the signal into an infrared signal which can be identified by the infrared receiving head; the infrared receiving head receives the reflected infrared signal. That is, when a person approaches the card from the front or the side, the person is detected by the front infrared emitting device and reflected back to the receiving head SNM437 by the infrared signal.
Step 2: the main control chip calculates the actual distance S1 between the personnel and the card machine through S =1/2 VT. Specifically, the receiving head transmits the received infrared signal to the main control chip, and the main control chip measures the horizontal distance S of a person in front of the card machine by using the infrared distance measurement principle, so that the horizontal position coordinate information S1 of one person can be obtained. Wherein, general card machine will set up an image frame at the screen interface of punching the card for correct personnel and punch the card distance d1 (the people stands in the card machine the preceding horizontal distance to the card machine), personnel only align the edge of face with the image frame, just can carry out the operation of people's face punching the card, if will force to dismantle the card machine, personnel must be close to the card machine, then the distance to the card machine this moment must be less than d1, the horizontal distance of side personnel to the card machine also can have a safety threshold value d2.
And 3, step 3: the interval is 0.5S, and the main control chip obtains the actual distance S2 of the card machine through S =1/2VT calculation personnel. Specifically, when the infrared emitting diodes and the infrared receiving heads which are positioned above and on the side face of the screen detect that a person approaches the card machine for the first time and the distance coordinate is S1, the infrared emitting diodes which are positioned on the front face at the interval of 0.5S perform infrared distance measurement again to obtain the distance coordinate information S2 of the person.
And 4, step 4: and the distance is 0.5S, and the main control chip calculates the actual distance S3 from the personnel to the card machine through S =1/2 VT. Specifically, the infrared emitting diode on the front side continuously emits pulse signals with fixed frequency, the infrared receiving head converts the received infrared signals into electric signals which can be identified by the chip, and the main control chip R818 calculates to obtain the coordinate information S3 of the position of the person at the moment by using the infrared distance measuring principle.
And 5: the average value of the three ranges & S2= (S1 + S2+ S3)/3 is calculated, and it is determined whether it is within the set threshold d2, i.e., & S2< d2. Specifically, an average value of three times of equal interval time ranging is calculated as a final distance position coordinate of the staff, an average value of the three times of ranging is obtained by using an average value calculation formula, and & S2= (S1 + S2+ S3)/3, the final distance position coordinate of the staff obtained by infrared ranging is compared with a front distance d2 of the card machine set by the main control chip R818, if & S2< d2, it is indicated that the current distance of the staff from the card machine is in an abnormal state, but it is not excluded that the distance position of the careless station is too close to the card machine when the staff performs the card punching operation, and therefore, the distance position obtaining and judgment of the staff in the first step to the fifth step are continued at this time.
And 6: and (5) circulating three times to obtain and judge the distance positions of the personnel from the first step to the fifth step. If the average values of the three distance measurements obtained at this time are & S2< d2, it can be judged that the distance between the person and the position coordinate is too close and smaller than the set threshold value d2.
And 7: and a timer arranged in the main control chip is used for timing, and whether the stay time of the personnel is within the time threshold range or not is judged (the stay time of the personnel in the card machine is not too long, and the personnel is judged to be abnormally close to the card machine if the stay time is too long).
And 8: and determining that the approach of the personnel is abnormal approach based on the fact that the stay time of the personnel is within the time threshold range, and starting the gyroscope to judge the attitude angle.
And step 9: and judging that the attitude angle &4 of the card machine is greater than the system set threshold &3 at the moment.
When people approach the card machine from the front or the side of the screen of the card machine, the card machine is forcibly detached, at the moment, because the fixed installation position of the card machine is changed, the built-in gyroscope LSM6DS3TR can trigger the attitude angle (acceleration and angular rate) detection of the gyroscope along with the change of the installation position of the card machine, and a normal attitude angle threshold range &3 can be set through the main controller R818. If the attitude angle detected by the gyroscope is within the range of the threshold value &3, the gyroscope LSM6DS3TR response is not triggered; if the gyroscope is installed outdoors and the attitude angle of the gyroscope is changed by 4< & gt 3 due to the position change of the card machine caused by wind and other inefficacy factors, the gyroscope does not report the attitude angle information to the main control chip R818; if the person forcibly carries out the violent disassembly, the posture angle detected by the gyroscope is &4> &3, and at the moment, the gyroscope sends the detected abnormal posture angle information to the main control chip R818 through a communication protocol.
Step 10: and transmitting the alarm signal to the mobile phone server through Wi-Fi.
The main control chip reports to the server through a WIFI communication interface of the storage card SDMMC, and the WIFI module WF-R189-SSH1 transmits signals to the mobile phone server, so that alarm is triggered. Optionally, the red RGB indicator light of the card machine is always on for warning.
Step 11: the mobile phone server receives the signal and sends out an alarm prompt.
In the embodiment, the human face card machine in the market generally performs anti-theft protection only by adopting a single accelerometer or gyroscope, if personnel cut off the power supply of the card machine in a special mode, the card machine cannot alarm the violent disassembly card machine, and great potential safety hazards exist. This embodiment adopts infrared range finding response and gyroscope acceleration and angular rate direction to detect the mode that combines together and carries out safety inspection, can just send the warning when unusual approaching, greatly reduced the potential safety hazard that adopts the power off mode to bring, infrared range finding technique is used comparatively extensively at present, moreover because the infrared transmitting and receiving device low price that adopts compares with the multisensor detection mode that adopts on the market, has very big cost advantage.
