Millimeter-wave radar works in the millimeter-wave band, which can identify very small targets, and at the same time measure the distance and speed of the target with high precision. In addition, the millimeter-wave radar has strong anti-interference ability and is not affected by the environment. Therefore, millimeter wave radar has been widely promoted in the civilian field, such as: vehicle reversing radar. The laser ranging sensor is a sensor that uses a laser diode to aim at the target to generate a laser pulse, and calculates the target distance by receiving and calculating the reflected light signal.

At present, how to remind the user to take the card at the first time has become one of the important ways to improve user experience and ensure the security of customer accounts.

The dotted line angle between the ATM machine and the scanning direction of the millimeter wave radar 110 is β. Meanwhile, by adjusting the parameters of the millimeter wave radar 110, the millimeter wave radar 100 can only scan users within the (-β, β) range; Under the condition that the millimeter wave radar 100 can at least scan the users within the range of (-β, β), the users of (-β, β) are screened out by the information fusion processing device 200 . Through the measurement of the millimeter wave radar 100 , the position information and speed information of the user within the scanning range are transmitted to the information fusion processing system through RS-232.

The laser ranging sensor 120 is a laser diode aimed at the target to emit laser pulses. After being reflected by the target, the laser light is scattered in all directions, and part of the scattered light returns to the sensor receiver, and is imaged to the photodiode after being received by the optical system.

In the embodiment of the present invention, the millimeter wave radar 110 is used to collect user location information, and send the user location information to the information fusion processing device 200 through the data transmission interface 101 at a first time interval.

The laser ranging sensor 120 is used to collect distance information, and send the distance information to the information fusion processing device 200 through the data transmission interface 101 at a second time interval.

It is worth noting that both the first time interval and the second time interval can be set according to actual needs. As an optional solution, the first time interval and the second time interval should be set as small as possible, so that the user's position can be real-time The information and distance information are sent to the information fusion processing device 200 .

Step 101, receiving detection data sent by the detection device, the detection data includes user location information and distance information.

Step 102, performing fusion processing on the user's location information and distance information to obtain a card withdrawal warning result.

Step 103: If the pre-warning result of card withdrawal includes pre-warning information of card non-taking, send the pre-warning information of not taking card to the pre-warning device, so that the pre-warning device can pre-warn the pre-warning of not taking the card according to the pre-warning information of not taking the card.

It is worth noting that the acquisition, storage, use, and processing of data in the technical solution of this application all comply with the relevant provisions of national laws and regulations. The user information in the embodiments of this application is obtained through legal and compliant channels, and the acquisition, storage, use, and processing of user information are authorized and agreed by the customer.

In the technical solution provided by the embodiment of the present invention, the detection data sent by the detection device is received, and the detection data includes user location information and distance information; the user location information and distance information are fused to obtain the card retrieval warning result; if the card retrieval warning result is Including the early warning information of not taking the card, the early warning information of not taking the card is sent to the early warning device, so that the early warning device can carry out the early warning of not taking the card according to the early warning information of not taking the card, and can carry out fusion detection of the user's user location information and distance information, the first Remind the user to take out the card in time to ensure the security of the user's account and improve the user experience.

Fig. 5 is a flow chart of another early warning method for card withdrawal provided by an embodiment of the present invention. As shown in Fig. 5, the method includes:

Step 201, receiving user location information sent by the millimeter wave radar through the data transmission interface at a first time interval.

In the embodiment of the present invention, each step is executed by an information fusion processing device.

In the embodiment of the present invention, the first time interval may be set according to actual needs, so as to realize real-time reception of user location information sent by the millimeter-wave radar.

Step 202, receiving the distance information sent by the laser ranging sensor through the data transmission interface according to the second time interval.

In the embodiment of the present invention, the second time interval can be set according to actual needs, so as to receive the distance information sent by the laser ranging sensor in real time.

Specifically, when the card slot is not blocked, the distance information collected by the laser ranging sensor is the distance from the position of the laser ranging sensor to the left side of the card slot, or the distance from the position of the laser ranging sensor to the left side of the ATM. The distance between the sides; when the card slot is blocked, the distance information collected by the laser ranging sensor is the distance from the position of the laser ranging sensor to the blocking object.

Step 203 , according to the user location information, determine whether there is target user information, if yes, perform step 204 ; if not, perform step 201 .

In the embodiment of the present invention, the user location information includes the distance between each user and the millimeter wave radar, the user orientation between each user and the millimeter wave radar, and the user speed of each user. Wherein, the user orientation is the relative angle between the user and the straight ahead of the millimeter-wave radar scan.

In the embodiment of the present invention, step 203 specifically includes:

Step 2031 , judging whether there is a candidate user whose user speed is zero, if not, execute step 2032 ; if yes, execute step 2033 .

In the embodiment of the present invention, the user speed of each user is judged. If there is no user whose user speed is zero, it indicates that each user is in a mobile state, that is, not a target user who is using an ATM machine, and continues to execute step 2032 If there is a user whose user speed is zero, it indicates that the user in a static state is a queue user or a user using an ATM machine, and the user whose speed is zero is determined as a candidate user, and step 2033 is continued.

Step 2032, determine that there is no target user information, and continue to execute step 201.

In the embodiment of the present invention, if each user is in a moving state, it indicates that there is no target user, and it is determined that there is no target user information, and the detection needs to be continued, and step 201 is continued.

Step 2033 , judging whether there are multiple candidate users, if yes, execute step 2034 ; if not, execute step 2035 .

In the embodiment of the present invention, if the number of candidate users is multiple, it indicates that there are both queuing users and users who are using the ATM machine, and it is necessary to further determine the target user from the candidate users, and continue to perform step 2034; if there is only one candidate user , indicating that the user is using the ATM machine, that is, the target user, the target user information can be determined directly, and step 2035 is continued.

Step 2034: Determine the target user according to the distance and user orientation between each candidate user and the millimeter-wave radar, the target user information includes the distance between the target user and the millimeter-wave radar, user orientation and user speed, and continue to step 204 .

In the embodiment of the present invention, the user orientation is the relative angle between the user and the front of the millimeter-wave radar scan. Specifically, taking the position of the millimeter-wave radar shown in Figure 2 as an example, according to the distance between each candidate user and the millimeter-wave radar and the user's orientation, the horizontal distance from the millimeter-wave radar in the horizontal direction is selected from multiple candidate users The user whose h is h and the user's orientation is closest to β (that is, the angle obtained by subtracting the user's orientation from β is the smallest) is determined as the target user.

Step 2035: Determine the candidate user as the target user, and the target user information includes the distance between the target user and the millimeter-wave radar, the user's orientation, and the user's speed.

In the embodiment of the present invention, the candidate user is a user who is using the ATM machine, that is, the target user.

Step 204 : Calculate the number of distance changes according to the plurality of distance information. If the number of distance changes is odd, perform step 205 ; if the number of distance changes is even, perform step 203 .

In the embodiment of the present invention, when the card slot is not blocked, the distance information collected by the laser ranging sensor is the distance from the position of the laser ranging sensor to the left side of the card slot, or the distance from the position of the laser ranging sensor The distance to the left side of the ATM is the same as the distance information received by the information fusion processing device, and the distance information will not change. When the user uses the ATM, the behavior of inserting and removing the card will occur. Every time the card is inserted and removed, the card slot will be blocked. The distance information measured by the laser ranging sensor is the position of the laser ranging sensor. The distance to the hand or the card, the distance information at this time is inconsistent with the distance information measured when the card slot is unobstructed, and the distance information received by the information fusion processing device will change. When the information fusion processing device detects a change in the distance information for the first time, it indicates the user's card insertion operation; when it detects the distance information change for the second time, it indicates the user's card removal operation, and so on. Therefore, the current operation of the user can be judged by counting the number of times the distance information changes.

Take the initial value of the number of distance changes as 0 or any even number as an example. Specifically, if the number of distance changes is an odd number, it indicates that the user's current operation is a card insertion operation, and the current card slot is in a card state, and proceed to step 205; if the distance changes If the number of times is an even number, it indicates that the user's current operation is to take out a card, and the target card slot is in a state of no card, and the step 203 is continued.

It is worth noting that if the initial value of the number of distance changes is any odd number, if the number of distance changes is an even number, it indicates that the user's current operation is a card insertion operation, and the current card slot is in a card state; if the number of distance changes is an odd number, it indicates that the user The current operation is to remove the card, and the target card slot is in the state of no card, so I won’t repeat it here.

In the embodiment of the present invention, step 204 specifically includes:

Step 2041 , judging whether the current distance information and the next distance information of the current distance information are the same, if they are the same, execute step 2042 ; if they are different, execute step 2043 .

In the embodiment of the present invention, if the two successively received distance information are the same, it indicates that the user's operation state of the card has not changed, and the execution continues to step 2042; if the two successively received distance information are different, it indicates that the user's operation status of the card If the operating state changes, continue to execute step 2043 .

Step 2042, determine the next distance information as the current distance information, and continue to execute step 2041.

In the embodiment of the present invention, the distance change is judged sequentially for each received distance information. Specifically, each time a piece of distance information is received, the next distance information of the current distance information is determined as the new current distance information, the received distance information is determined as the next distance information of the new current distance information, and step 2041 is repeatedly executed.

Step 2043 , add 1 to the set number of distance changes to obtain the accumulated number of distance changes, and repeatedly execute step 2042 .

In the embodiment of the present invention, the initial value of the number of distance changes may be set according to actual requirements.

Specifically, if the two successively received distance information are different, the number of distance changes is added by one to obtain the accumulated number of distance changes, and step 2042 is continued.

Step 205, secondly judge whether the target user information exists, and obtain the result of the second judgment.

In the embodiment of the present invention, if the user's current operation is a card insertion operation, and the current card slot is in a card state, it is necessary to judge whether the target user still exists, and obtain a second judgment result.

Specifically, according to the user location information received in real time, it is judged whether there is target user information. It is worth noting that the method for the secondary determination of the target user information is the same as step 203, and will not be repeated here.

Step 206: Generate a card withdrawal warning result according to the second judgment result, if the card withdrawal warning result includes no card withdrawal warning information, perform step 207; if the card withdrawal warning result includes no card withdrawal warning, perform step 204.

Specifically, if the second judgment result exists, it indicates that the user has not taken the card but is still using the ATM machine, and generates an early warning result for taking the card without warning, and continues to perform step 204; if the second judgment result does not exist, it indicates that the user has not taken the card. If the card has already left the ATM, a pre-warning result of card pre-emption is generated, and step 207 is continued.

Step 207 , sending the pre-warning information of not taking the card to the pre-warning device, so that the pre-warning device can perform pre-warning of not taking the card according to the pre-warning information of not taking the card.

In the embodiment of the present invention, the pre-warning information of not taking the card is sent to the pre-warning device through the data transmission interface, and the pre-warning device performs the pre-warning of not taking the card in response to the pre-warning information of not taking the card. It is worth noting that the early warning method can be set according to actual needs, including but not limited to one or any combination of voice broadcast, ringing and light reminders, and the embodiment of the present invention does not limit the early warning method. As an optional solution, considering the diversity and complexity of user groups, a combination of voice broadcast and light reminder can be used to give users an early warning of card failure.

The present invention adopts the multi-sensor combination of the most rapidly developed millimeter-wave radar and the relatively mature laser ranging sensor, and through the fusion processing of the data information collected by the two, it can effectively detect whether the user takes the card when leaving the ATM, If the user does not take the card, the user is reminded to take the card through voice broadcast and light reminder, which improves the user experience of the user and reduces the risk of account funds being taken away by others due to the user not taking the card.

It is worth noting that the acquisition, storage, use, and processing of data in the technical solution of this application all comply with the relevant provisions of national laws and regulations. The user information in the embodiments of this application is obtained through legal and compliant channels, and the acquisition, storage, use, and processing of user information are authorized and agreed by the customer.
