Description

Technical Field

[0001] The present application relates to the field of gate control, and in particular to a gate control method and device, electronic equipment and storage medium. Background Art

[0002] The gate system is mainly composed of a box, a barrier, a movement, a control module and other components. The barrier can be used to regulate the entry and exit of pedestrians and effectively control the flow of people. At present, most office buildings, schools, and high-speed rail station entrances use gates to control the interception and release of pedestrians. They use cards, certificates, codes, etc. to verify the identity and open the barrier to pass through. If the recognition fails due to special reasons such as facial changes or poor network signals, the waiting time will be increased, causing dangerous congestion of people; in addition, the gate relies on infrared rays to determine the departure of the object. If the infrared detection next to the gate is covered when the previous person passes, the barrier will remain open, and the inaccessible object will also be able to enter, which may cause certain safety hazards to enterprises or individuals; or for the three-roller gate, if you are holding large luggage or carrying things in both hands, it is not only easy to cause damage to the gate and cannot be used normally, but also easy to cause certain safety hazards to the object.

[0003] There is currently no effective solution to the above problems in the prior art. Summary of the invention

[0008] Optionally, after issuing the alarm, the method further comprises: canceling the alarm after neither the first millimeter wave radar device nor the radio frequency identification reader / writer recognizes the first target object.

[0009] Optionally, the method also includes: when the second millimeter-wave radar device identifies that the second target object is passing in the opposite direction, controlling the gate to sound an alarm; after the first millimeter-wave radar device and the second millimeter-wave radar device identify that an object with matching tag information has passed through the gate, controlling the gate of the gate to close.

[0010] Optionally, the method further includes: controlling the gate to cancel the alarm when the second millimeter-wave radar device and the first millimeter-wave radar device fail to identify the second target object; or controlling the gate to cancel the alarm when the radio frequency identification reader recognizes the tag information of the second target object and the tag information of the second target object is consistent with the pre-stored tag information.

[0011] Optionally, the method further includes: if the tag information of the first target object is not identified, identifying the first target object that enters the gate again in the forward direction by using the radio frequency identification reader / writer.

[0012] In the second aspect, the present application provides a control device for a gate, comprising: a first identification module, used to identify a first target object that is entering the gate in the forward direction through a radio frequency identification reader / writer; a first control module, used to continue to control the gate of the gate to be normally open when it is identified that the tag information of the first target object is consistent with the pre-stored tag information; a second control module, used to control the gate to issue an alarm and identify the movement trajectory of the first target object through a first millimeter-wave radar device to control the opening and closing state of the gate when it is identified that the tag information of the first target object is inconsistent with the pre-stored tag information, or the tag information of the first target object is not identified, wherein the first millimeter-wave radar is used to identify objects between the radio frequency identification reader / writer and the gate.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0027] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] In order to solve the problem of low gate efficiency and great safety hazards in the prior art, the present application provides a gate control method, such as Figure 1 As shown, the steps of the method include:

[0029] Step 101, identifying a first target object entering the gate through a radio frequency identification reader;

[0030] In the embodiment of the present application, the RFID reader is an RFID reader based on RFID (Radio Frequency Identification) technology. That is, the RFID reader in the embodiment of the present application can identify a specific target and read and write related data through radio signals without the need to establish mechanical or optical contact between the recognition system and the specific target. Compared with the high requirements for face recognition accuracy in face recognition, the RFID reader in the embodiment of the present application can directly identify a specific target, such as a work badge or other documents. Compared with the complexity of face recognition, the recognition efficiency of a specific target through an RFID reader is higher.

[0031] Step 102, when it is identified that the tag information of the first target object is consistent with the pre-stored tag information, continue to control the gate of the gate machine to be in a normally open state;

[0032] In the embodiment of the present application, the tag information is information that can uniquely identify the first target object, for example, each target object has a unique corresponding identification code. In addition, the gate of the gate machine in the embodiment of the present application is normally open in the normal state, that is, as long as the identified object is a passable object (the identified tag information is consistent with the pre-stored tag information), it can directly pass through the gate. Compared with the prior art, the gate is a three-roller gate or a four-roller gate. Even if it is a passable object, the object needs to turn the three-roller gate before passing. The gate in the present application is in a normally open state. When the identified object is a passable object, it can pass directly without any operation of the object, and its passage efficiency is higher.

[0033] Step 103, when it is identified that the tag information of the first target object is inconsistent with the pre-stored tag information, or the tag information of the first target object is not identified, the gate is controlled to issue an alarm and identify the movement trajectory of the first target object through the first millimeter wave radar device to control the opening and closing state of the gate, wherein the first millimeter wave radar is used to identify the object between the radio frequency identification reader and the gate.

[0034] It can be seen that in the embodiment of the present application, when the identified object is an impassable object, or the tag information of the object is not identified, an alarm can be issued to notify the security object, and the movement trajectory of the object can also be identified by the millimeter wave radar device. If the impassable object continues to pass through the gate, the gate can be controlled to close. If the impassable object exits the gate, the alarm can be lifted and the gate can be kept in a normally open state without affecting the passage of other impassable objects.

[0035] It can be known from the above steps 101 to 103 that in the embodiment of the present application, the gate of the gate machine is in a normally open state. Therefore, when the first target object passing in the forward direction is identified and passed by the radio frequency identification reader, the first target object can be allowed to pass directly without any other operation. In addition, if the tag information of the first target object is inconsistent with the pre-stored tag information or the tag information is not identified, the movement trajectory of the first target object can be further identified by the first radar millimeter wave device to control the opening and closing state of the gate. For example, if the impassable object continues to pass through the gate machine, the gate can be controlled to close, or if the impassable object exits the gate machine, the gate is kept in a normally open state, which does not affect the passage of other passable objects. Through the embodiment of the present application, compared with the prior art, not only the recognition efficiency of the gate machine can be improved, but also the passage efficiency can be guaranteed to be high when the recognition efficiency is high.

[0036] In a specific example, there may be a situation where recognition is unavailable, for example, the recognized object is blocked, and the tag information of the object may need to be recognized again. Therefore, if the tag information of the first target object is not recognized, the first target object that enters the gate again in the forward direction can be recognized by the RFID reader.

[0037] In the embodiment of the present application, multiple RFID readers can be set to meet the needs of different target objects. For example, taking work ID as an example, the work ID of each target object entering the gate is usually worn on the chest, but the height of each target object is different. Therefore, two RFID readers can be set up to identify objects of different heights to improve the recognition efficiency of the target object's tag information. Based on this, the method of identifying the first target object entering the gate in the forward direction through the RFID reader involved in the above step 101 can further include:

[0038] Step 11, identifying the first target object entering the gate by the first RFID reader / writer and / or the second RFID reader / writer; wherein the first RFID reader / writer and the second RFID reader / writer are arranged inside the gate and at different heights on the same vertical line.

[0039] It can be seen that in the embodiment of the present application, by using two RFID readers at different heights on the same vertical line inside the gate, target objects of different heights can be identified. Specifically, the recognition width of the two RFID readers is the width of a person, which can avoid identifying multiple objects at the same time and causing misidentification of tag information. If two objects are identified at the same time, the tag information of one of them is consistent with the pre-stored one, and the tag information of the other is not identified, then it is unclear which object is a passable object. However, in some cases, even if the recognition width of the RFID reader is the width of a person, it is possible to identify the tag information of two or more objects. At this time, if the identified tag information can all match, then voice broadcast "all can pass" can be made. If there are inaccessible objects, the name of the passable object can be voice broadcast, such as "XXX can pass", so that the security object can be reminded to further confirm who can pass and who cannot pass. In other words, after multiple target objects are identified at the same time, voice broadcast can be made according to the matching recognition results of the tag information for reminder. In addition, there is an area where the heights of the two RFID readers in the embodiment of the present application overlap. If the target to be identified by the current target object is in this area, only one of the two RFID readers is required to identify the tag information. As for the non-overlapping areas, this is to meet the needs of objects of different heights.

[0040] In the embodiment of the present application, after identifying an impassable object, the movement trajectory of the object can be further identified by the first millimeter wave radar device. If the impassable object continues to pass through the gate, the gate can be controlled to close to prevent the object from passing through the gate. If the impassable object does not continue to pass through the gate, the gate of the gate can be controlled to continue to remain in a normally open state to ensure the normal passage of other objects. Based on this, the method involved in the above step 103 in the embodiment of the present application of identifying the movement trajectory of the first target object by the first millimeter wave radar device to control the opening and closing state of the gate can further include:

[0041] Step 21, when the first millimeter wave radar device identifies that the first target object does not continue to pass, the gate is controlled to continue to be normally open, and the gate machine is controlled to continue to issue an alarm;

[0042] Step 22, when the first millimeter-wave radar device identifies that the first target object continues to pass, the gate is controlled to continue to issue an alarm, and after the first millimeter-wave radar device identifies that the object before the first target object has passed through the gate, the gate of the gate is controlled to close.

[0043] It can be seen that in the embodiment of the present application, if an impassable object is identified, the movement trajectory of the object will continue to be identified through the first millimeter-wave radar device to determine whether to close the gate. That is, in the embodiment of the present application, the trajectory of a passable object can be identified by the first millimeter-wave radar device, and only after the passable object passes, the gate of the gate machine will be controlled to close to ensure the normal passage of the passable object. It can be seen that in the embodiment of the present application, the first millimeter-wave radar device can not only restrict the passage of impassable objects, but also ensure the normal passage of passable objects, ensuring the passage efficiency while also ensuring the accuracy of the passage.

[0044] In the embodiment of the present application, after the alarm is issued, the method of the embodiment of the present application further includes:

[0045] Step 31, canceling the alarm after the first millimeter wave radar device and the radio frequency identification reader / writer fail to identify the first target object.

[0046] It can be seen that if an impassable object is identified, even if the impassable object may continue to pass, it may exit the gate after hearing the alarm, that is, the first millimeter wave radar device and the radio frequency identification reader / writer have not identified the impassable object. At this time, the gate can be controlled to release the alarm and return to the normal identification process. That is, in the embodiment of the present application, the movement trajectory of the impassable object can be further identified by the first millimeter wave radar device and the radio frequency identification reader / writer to determine whether the impassable object accidentally enters or forcibly passes through the gate.

[0047] In the embodiment of the present application, for the passage of the gate, in some cases, there may be a target object that uses the gate entrance as the gate exit, that is, the target object may pass in the opposite direction. In the embodiment of the present application, the second millimeter wave radar device can be used to identify the object passing in the opposite direction. If an object passing in the opposite direction is identified, an alarm needs to be issued and the gate of the gate needs to be closed. Based on this, Figure 2 As shown, the method steps of the embodiment of the present application may also include:

[0048] Step 201, when the second millimeter wave radar device recognizes that the second target object is passing in the opposite direction, the gate is controlled to issue an alarm;

[0049] Step 202: After the first millimeter wave radar device and the second millimeter wave radar device identify that an object with matching tag information has passed through the gate, the gate of the gate is controlled to be closed.

[0050] The second millimeter wave radar device in the embodiment of the present application is arranged inside the gate and at a position where an object passing through the reverse channel can be identified. It can be seen that in the embodiment of the present application, after the second millimeter wave radar device identifies an object passing in the reverse direction, it can first identify the object passing normally and then close the gate of the gate, which can prevent the object from passing through the gate in the reverse direction without affecting the normal passage, thus avoiding the occurrence of potential dangers.

[0051] Further, in the embodiments of the present application, Figure 2 Based on this, the method of the embodiment of the present application is as follows Figure 3 As shown, it may also include:

[0052] Step 301, when the second millimeter wave radar device and the first millimeter wave radar device fail to identify the second target object, control the gate to release the alarm; or,

[0053] Step 302: When the RFID reader recognizes the tag information of the second target object and the tag information of the second target object is consistent with the pre-stored tag information, control the gate to release the alarm.

[0054] It can be seen that in the embodiment of the present application, after identifying the object passing in the opposite direction, the movement trajectory of the target object can be further identified. If neither the second millimeter-wave radar device nor the first millimeter-wave radar device identifies the object passing in the opposite direction, it indicates that the object passing in the opposite direction has exited the gate. At this time, there is no need to continue to issue an alarm and the alarm can be lifted. In addition, if the second target object enters the wrong entrance, the tag information of the object is identified by the radio frequency identification reader after a period of time after it is identified in the direction channel, and when the tag information of the object is consistent with the pre-stored tag information, it indicates that the object can pass normally, and the alarm can be lifted at this time.

[0055] The present application is explained below in conjunction with the specific implementation of the embodiment of the present application. The specific implementation provides an intelligent control method for gates based on RFID. In this specific implementation, the gate has no obstruction (i.e., no gate) in the normal state, and the relevant information of the tag within the detection range corresponding to the reader is obtained in real time through RFID, and transmitted to the background management system for analysis and matching, and the matching information is synchronously transmitted to the millimeter-wave radar, alarm, and obstruction system. For objects with abnormal tags or without tags, the millimeter-wave radar can be used to detect the activity trajectory of the passing object in real time, and the alarm and obstruction can be called to perform different operation steps for different abnormal situations, effectively improving the passage efficiency of the passing object and effectively and reasonably controlling the execution status of the gate for different situations.

[0056] Based on this, combined Figure 4It can be seen that the gate starts to operate and the gate is initially in the normally open state. Install RFID readers and antennas, as well as millimeter-wave radars on the gate, and bind them to the background management system respectively. Install the RFID reader and antenna on the inside of the gate entrance X1 (first RFID reader) and X2 (second RFID reader), install the millimeter-wave radar X3 (first millimeter-wave radar device) between the reader and the gate, and X4 (second millimeter-wave radar device) at the gate exit, behind the gate (specific location as shown in the figure below). Figure 4 As shown in the figure, the RFID reader and the antenna, the millimeter wave radar, the alarm, the barrier control system, and the background management system are connected to each other. Set h as the reading range of the RFID reader (h is the width that only one person can pass through), which is also the detection area range of the millimeter wave radar X3 and X4. Set the forward direction of the object to be from a to b. Based on this, the method steps in this specific implementation are as follows: Figure 5 As shown, it may include:

[0057] Step 501, the gate is running and the gate is always open.

[0058] Step 502, if the object enters the gate from the forward direction (i.e., from a to b);

[0059] Step 503, determine whether there is a label, if there is a label, execute step 504, if there is no label, execute step 507.

[0060] Step 504, detect the tag and transmit it to the backend management system for analysis and matching;

[0061] Step 505, synchronously returning the analysis and matching results to the gate, alarm and X3;

[0062] Step 506: Check if the tag information is consistent. If it is consistent, the vehicle can be directly allowed to pass. If it is inconsistent, an alarm is issued.

[0063] Step 507: X1 / X2 does not detect the tag, and X3 does not receive the tag matching information returned by the background;

[0064] Step 508, X3 detects that someone is passing;

[0065] Step 509, issuing an alarm;

[0066] Step 510, detecting whether the object continues to pass, if yes, executing step 511, if no, executing step 512;

[0067] Step 511, continue to alarm, X3 continues to monitor, and pops up the gate after ensuring that the previous person has passed;

[0068] Step 512, continue to alarm, and the gate remains in the initial normally open state;

[0069] Step 513, the tag exits the gate, and the alarm stops if it is not within the X1 / X2 reading range;

[0070] Step 514, if the object enters the gate from the reverse direction (i.e., from b to a), the millimeter wave radar X4 detects the position of the object;

[0071] Step 515, the millimeter wave radar X4 detects the reverse passage of a person;

[0072] Step 516, calling the alarm system to trigger the alarm, synchronously detecting the position information of other objects at X3 / X4, and popping up the gate in time to control the reverse passage while ensuring the safety of other objects.

[0073] Step 517, when X4 detects that the object exits the gate exit and passes forward, the alarm is stopped and the gate returns to the initial normally open state.

[0074] Since the current gates rely on recognition cards, faces, barcodes / QR codes for passage, and the barriers used are mostly swing gates and three-roller gates, if the flow of people is too large and the recognition accuracy is not high due to special reasons, it is easy to cause congestion. For three-roller gates, it is extremely inconvenient for people with a lot of luggage to pass, and it is more likely to cause damage to the gate machine. In addition, if the infrared judgment is blocked artificially, it is easy to cause the gate machine to open abnormally, which poses certain safety hazards to enterprises or individuals.

[0075] In this regard, the RFID reader on the gate in this specific implementation method identifies and reads the data of the tag entering the reading and writing range, and transmits the received data to the background management system for information matching. If it matches the information in the database, the person can pass through the gate directly, avoiding the congestion of people caused by the speed of the gate identification device, improving the efficiency of passage, and avoiding behaviors that are prone to safety hazards such as pinching and injuring people due to abnormal closure of the gate; if the corresponding data item is not found in the database, an alarm will be issued and a blocking plate will pop up for interception, effectively preventing illegal intrusion of people who do not meet the requirements, and ensuring the safety of life and property of people or enterprises. In addition, with the assistance of millimeter-wave radar, people without tags can be effectively detected and people with abnormal tags can be prevented from following.

[0076] Corresponding to the above Figure 1 The present application also provides a gate control device, such as Figure 6 As shown, the device comprises:

[0077] The first identification module 602 is used to identify the first target object entering the gate through the radio frequency identification reader;

[0078] The first control module 604 is used to continue to control the gate of the gate machine to be in a normally open state when the tag information of the first target object is identified to be consistent with the pre-stored tag information;

[0079] The second control module 606 is used to control the gate to issue an alarm and identify the movement trajectory of the first target object through the first millimeter wave radar device to control the opening and closing state of the gate when the tag information of the first target object is identified to be inconsistent with the pre-stored tag information, or the tag information of the first target object is not identified. The first millimeter wave radar is used to identify the object between the radio frequency identification reader and the gate.

[0080] Through the device of the embodiment of the present application, the gate of the gate machine is in a normally open state. Therefore, when the first target object passing in the forward direction is identified and passed by the radio frequency identification reader, the first target object can be allowed to pass directly without any other operation. In addition, if the tag information of the first target object is inconsistent with the pre-stored tag information or the tag information is not identified, the movement trajectory of the first target object can be further identified by the first radar millimeter wave device to control the opening and closing state of the gate. For example, if the impassable object continues to pass through the gate machine, the gate can be controlled to be closed, or if the impassable object exits the gate machine, the gate is kept in a normally open state without affecting the passage of other passable objects. Through the embodiment of the present application, compared with the prior art, not only the recognition efficiency of the gate machine can be improved, but also the passage efficiency can be guaranteed to be high when the recognition efficiency is high.

[0082] In an optional implementation of an embodiment of the present application, the second control module in the embodiment of the present application may include: a first control unit, used to control the gate to continue to be open and control the gate machine to continue to issue an alarm when the first millimeter-wave radar device identifies that the first target object continues to pass, and a second control unit, used to control the gate machine to continue to issue an alarm when the first millimeter-wave radar device identifies that the first target object continues to pass, and control the gate of the gate machine to close after the first millimeter-wave radar device identifies that the previous object of the first target object has passed through the gate machine.

[0083] In an optional implementation of the embodiment of the present application, after the alarm is issued, the device in the embodiment of the present application may further include: a second control module, which is used to cancel the alarm after the first millimeter wave radar device and the radio frequency identification reader / writer fail to identify the first target object.

[0084] In an optional implementation manner of the embodiment of the present application, the device in the embodiment of the present application may also include: a third control module, used to control the gate to issue an alarm when the second millimeter-wave radar device identifies that the second target object is passing in the opposite direction; a fourth control module, used to control the gate of the gate to close after the first millimeter-wave radar device and the second millimeter-wave radar device identify that the object with matching tag information has passed through the gate.

[0085] In an optional implementation manner of the embodiment of the present application, the device in the embodiment of the present application may also include: a fifth control module, used to control the gate to cancel the alarm when the second millimeter-wave radar device and the first millimeter-wave radar device fail to identify the second target object; or, a sixth control module, used to control the gate to cancel the alarm when the radio frequency identification reader recognizes the tag information of the second target object and the tag information of the second target object is consistent with the pre-stored tag information.
