For convenience of explanation, the present embodiment is exemplified by one smart door access control device 120, but the present application is not limited thereto.
For example, the server 110 may be configured to assign a delivery order to the intelligent terminal 130 bound by the delivery personnel, and obtain the MAC address of the intelligent terminal 130, and send the MAC address to the target intelligent access control device 120 as a temporary MAC address, where the destination of the delivery order is located in the area of the target intelligent access control device 120, and the delivery order is completed through the access gate 122 of the target intelligent access control device 120. Different intelligent access control devices 120 may correspond to the same region, and therefore, the temporary MAC address here is issued to the target intelligent access control device 120, which may be a plurality of intelligent access control devices 120 in the region, and this is not limited herein.

The main control unit 1211 is configured to execute the intelligent access control method based on wireless communication, so as to implement the function of the intelligent access temporary passing system 100 based on wireless communication.
Referring to fig. 2, fig. 2 is a flowchart of an intelligent access control method based on wireless communication according to an embodiment of the present application.
In this embodiment, the intelligent access control method based on wireless communication is applied to the main control unit 1211 of the access control module 121 and may include step S10, step S20, step S30, step S40 and step S50.

Step S10: and acquiring a temporary MAC address sent by the server received by the upper communication unit, pre-storing the temporary MAC address, and adding the temporary MAC address into a pre-stored MAC address list, wherein the temporary MAC address sent by the server is an MAC address of an intelligent terminal corresponding to a distribution order distributed by the server, the distribution order is targeted in an area where the intelligent access control device is located, and the intelligent terminal is an intelligent terminal bound by a distribution person assigned by the server.
In this embodiment, the main control unit 1211 may obtain the temporary MAC address sent by the server 110 and received by the upper communication unit 1212, pre-store the temporary MAC address, and add the temporary MAC address to the pre-stored MAC address list.
The wireless communication unit 1213 may detect, in real time, the external smart terminal 130 entering the sensing range (where the external smart terminal 130 is distinguished from the foregoing smart terminal 130 in name, and the external smart terminal 130 may be the smart terminal 130 of the resident in the local cell, the smart terminal 130 of the distributor, or the smart terminal 130 of other pedestrians), establish wireless communication with the smart terminals 130, obtain the device MAC addresses of the smart terminals 130, and detect the signal strength when communicating with the smart terminals, as the device information corresponding to the smart terminals 130.

It should be noted that the real-time detection process of the wireless communication unit 1213 and the process of pre-storing the temporary MAC address by the main control unit 1211 are independent of each other, and there is no strict execution sequence distinction, which is not limited herein.
After acquiring the device information, the main control unit 1211 may perform step S30.
Step S30: and judging whether the equipment MAC address belongs to a pre-stored MAC address or not, wherein the pre-stored MAC address comprises a permanent MAC address and a temporary MAC address.
In this embodiment, the main control unit 1211 may determine whether the device MAC address belongs to a pre-stored MAC address, where the pre-stored MAC address includes a permanent MAC address (for example, the MAC address of the smart terminal 130 used by the resident is pre-stored as the permanent MAC address, and may be modified, deleted, or the like) and a temporary MAC address (for example, the MAC address of the smart terminal 130 bound by the delivery personnel is pre-stored as the temporary MAC address).
The main control unit 1211 determines whether the device MAC address belongs to the pre-stored MAC address, which may be determined by the main control unit 1211 determining whether the device MAC address is pre-stored by table lookup and matching.

In addition, since the pre-stored MAC address may be a permanent MAC address or a temporary MAC address, the main control unit 1211 does not need to be erased for the permanent MAC address. In order to ensure the reliability of the security system, a corresponding elimination operation needs to be performed on the temporary MAC address. Therefore, the main control unit 1211 may perform step S50 for the case where the device MAC address belongs to the temporary MAC address.
Step S50: and if the equipment MAC address belongs to the temporary MAC address, eliminating the equipment MAC address from the pre-stored MAC address list after generating control information.
In this embodiment, the main control unit 1211 may remove the device MAC address from the pre-stored MAC address list after generating the control information.

Further, if the device MAC address belongs to the temporary MAC address, the device MAC address is removed from the pre-stored MAC address list after the control information is generated. In this way, a temporary "pass order" may be established for the delivery personnel, and the MAC address of the intelligent terminal 130 bound by the delivery personnel is temporarily pre-stored, so that the delivery personnel may pass through the intelligent access control device 120 by using the MAC address of the intelligent terminal 130 bound by the delivery personnel. After the delivery personnel enter, the MAC address of the equipment (namely the MAC address of the intelligent terminal 130 bound by the delivery personnel) can be eliminated from the pre-stored MAC address list, so that the delivery personnel cannot utilize the MAC address of the intelligent terminal 130 bound by the delivery personnel to pass through the intelligent access control device 120 again before next delivery orders in the area are received, the safety of the community (or buildings such as office buildings) is greatly improved, the convenience of the personnel in the interior can be ensured, and the personnel do not need to take articles from the door. In addition, the mode can realize contactless access control verification, people (internal personnel, using a permanent MAC address; distribution personnel, using a temporary MAC address) are not required to carry out close-distance manual card swiping verification, the method is very convenient, personal privacy information such as faces and fingerprints is not required to be input, and the safety of the personal information is improved. Overall, this scheme can realize that user and delivery personnel do not have the current entrance guard floodgate machine of operation formula (can save time to the delivery personnel), and lower to intelligent access control device 120's hardware requirement, can reduce manufacturing cost.
In this embodiment, the wireless communication unit 1213 may be a bluetooth module, and correspondingly, the Signal Strength is an RSSI (Received Signal Strength Indication) value, and then the main control unit 1211 may determine the separation distance by using the following method:
for example, the master unit 1211 may substitute the RSSI value into the following equation:
wherein d represents a separation distance; RSSI represents the RSSI value; a represents the signal strength when the transmitting end is 1 meter away from the receiving end, i.e., the signal strength when the external smart terminal 130 is 1 meter away from the wireless communication unit 1213; n represents an environmental attenuation factor; abs () represents an absolute value function.
Thus, the separation distance d can be calculated by the formula (1).
The bluetooth module is used as the wireless communication unit 1213, so that the intelligent terminals 130 near the intelligent access control device 120 (the access control module 121 and the access controller 122) can be effectively detected, bluetooth communication is established to obtain the spacing distance between the intelligent terminals 130, and whether the access controller 122 is opened or not is judged. The calculation method can effectively and accurately determine the distance between the intelligent terminal 130 and the Bluetooth module, and the effectiveness of the intelligent access control method based on wireless communication is ensured.
In this embodiment, the specific manner of generating the control information and sending the control information to the driving unit 1214 when the separation distance satisfies the distance condition may be as follows:
the main control unit 1211 may obtain a current state of the access gate 122, where the current state is an open state or a closed state, the open state indicates that the access gate 122 is in the process of being opened or is kept open, and the closed state indicates that the access gate 122 is in the process of being closed or is kept closed.
When the current state is the off state, the main control unit 1211 may determine whether the spaced distance is within the first distance range, and generate control information to transmit to the driving unit 1214 when the spaced distance is within the first distance range.
When the current state is the on state, the main control unit 1211 may determine whether the distance is within the second distance range, and generate control information to transmit to the driving unit 1214 when the distance is within the second distance range. Here, the maximum distance value of the second distance range is greater than the maximum distance value of the first distance range.
Different opening standards are respectively set for different states (opening states or closing states) of the current state of the access gate 122: for the condition that the access gate 122 is in the closed state, by judging whether the separation distance is within the first distance range, and when the separation distance is within the first distance range, generating control information and sending the control information to the driving unit 1214; for the situation that the access control gate 122 is in the open state, it is determined whether the distance is within the second distance range, and when the distance is within the second distance range, the control information is generated and sent to the driving unit 1214, wherein the maximum distance value of the second distance range is greater than the maximum distance value of the first distance range. In such a case, it can be fully considered that the door lock 122 only needs to be normally opened when being in a closed state, and the time spent is short; when the access control gate 122 is in the open state, the situation that the later person accelerates the foot to enter is usually caused, so that the situations of collision, falling and the like are easy to occur. If the door is opened according to the normal judgment distance (the first distance range), the door lock 122 is closed, and the following person enters the first distance range to open the door, which results in frequent opening and closing of the door lock 122, wastes energy, and is more likely to cause aging of the door lock 122 and psychological stress on the following person. Therefore, when the access control gate 122 is in the open state, the more sufficient time is reserved for the following personnel by adopting different judgment standards when the access control gate is in the closed state, so that the situations of collision, falling and the like caused by urgent running of the personnel are avoided as much as possible, energy can be saved, and the aging of the access control gate 122 is slowed down.
Illustratively, the distance between the entrance and the exit of the access gate 122 is y meters or more (e.g., 5 meters or more, 10 meters or more, and 5 meters as an example), and the time required for the access gate 122 to switch from on to off is t seconds (e.g., 3 seconds, 5 seconds, and 3 seconds as an example).
Then the maximum value of the first distance range is x1M (e.g. 2 m, 3 m, etc., preferably 2 m), and the maximum value of the second distance range is x2Meter (e.g., 5 meters, 8 meters, etc.), wherein the set distance y is greater than the maximum x of the second distance range2And x is1And x2The following conditions are satisfied:
x1+1.5t≥x2≥x1+0.5t， (2)
wherein t is more than 0 and less than or equal to 5.
In this way, the maximum value of the first distance range is determined to be x1And the maximum value of the second distance range is x2And the maximum value x of the second distance range is determined considering that the time required for the entrance guard gate 122 to switch from on to off is t seconds2The value of (a). The coefficient 0.5 is a low value, and may be regarded as a speed (within the sensing range of the wireless communication unit 1213) when a person normally walks in the area between the first distance range and the second distance range, and the coefficient 1.5 is a high value, and may be regarded as a speed (within the sensing range of the wireless communication unit 1213) of a riding person (e.g., a delivery person) and a driving person (e.g., a resident) in the area between the first distance range and the second distance range, so that an appropriate coefficient value may be selected and set according to different cell conditions (e.g., whether the riding person is allowed to pass through, whether the driving person is allowed to pass through, an actual traffic road condition in the area between the first distance range and the second distance range, etc.). Moreover, the maximum values of the second distance ranges are all located in the effective communication range of the bluetooth module (or the common wireless communication unit 1213 such as WIFI)(typically 10 meters and more) to ensure feasibility of the solution.
In this embodiment, for the case that the device MAC address belongs to the temporary MAC address, after the control information is generated, the main control unit 1211 may further record a passing time point at which the control information is generated, and associate the passing time point with the device MAC address; the transit time point and the associated device MAC address are returned to the server 110 through the upper communication unit 1212. The server 110 may determine whether the distributor has a dishonest behavior of completing the distribution order by clicking in advance based on the passing time point and the completion time point of the distribution order corresponding to the device MAC address.
The passing time point of the intelligent access control device 120 of the area where the delivery personnel can reach (can also be understood as passing) can be accurately obtained by utilizing the passing time point for generating the control information, can be used as a strong basis for judging whether the delivery personnel has a non-honest behavior of clicking in advance to finish the delivery order, can effectively check the general situation that the delivery personnel click in advance to finish the order without reaching the object, can protect the interests of the user (such as the rights and interests of similar right and interests guarantee products such as 'right keeping' and the like) as much as possible, is good for improving the quality of the delivery personnel by monitoring, thereby improving the viscosity of the user, realizing the reliability of a platform party (improving the satisfaction degree of the user), a user party (a convenient living mode), a delivery personnel party (eliminating the delivery personnel with low quality, guaranteeing the interests of the delivery personnel with high quality) and a security protection party (capable of ensuring the reliability of a security system, reducing the cost of manpower and material resources spent on screening suspicious alien personnel).
In this embodiment, the specific way for the main control unit 1211 to remove the device MAC address from the list of pre-stored MAC addresses may be: acquiring a current time point; judging whether the interval between the current time point and the passing time point reaches a set time length or not, wherein the value range of the set time length is 30-150 seconds; and after the interval between the current time point and the passing time point reaches the set duration, eliminating the equipment MAC address from the pre-stored MAC address list.
In the implementation mode, after the interval between the current time point and the passing time point reaches the set time length (the value range is 30-150 seconds), the MAC address of the equipment is eliminated from the pre-stored MAC address list, so that a certain time can be reserved for distribution personnel, and the distribution personnel need to stop the electric motorcycle at the roadside (possibly located in the second distance range or even the first distance range) because the electric motorcycle is not allowed to pass through in some districts, and take out the articles from the standby box to pass through the access gate 122. Therefore, the reserved time can be reserved for the operation of the distribution personnel, and the method is more practical.
In addition, the following method may be specifically adopted for the server 110 to determine whether the delivering personnel has a dishonest behavior of completing the delivery order by clicking in advance:
the server 110 may determine whether the transit time point is after the completion time point of the delivery order.
If the transit time point is after the completion time point of the delivery order, the server 110 may determine that the delivery person has a dishonest behavior of clicking in advance to complete the delivery order (because the delivery person has not yet reached the gate 122 of the target smart gate 120). The server 110 may then obtain the estimated delivery time (an average time may be obtained from past mass delivery data as the estimated delivery time, or may alternatively obtain the estimated delivery time in other manners, which is not limited herein), which is required from the gate 122 of the target smart gate 120 to the destination of the delivery order, and correct the real completion time point of the delivery order based on the transit time point and the estimated delivery time. For example, the transit time point plus the estimated delivery time is taken as the actual completion time point of the delivery order.
If the transit time point is not located after the completion time point of the delivery order, the server 110 may obtain the delivery time points fed back by the user of the delivery order (some delivery orders, the user may actively correct the actual delivery time point, some delivery orders, the user may not actively correct, and the discussion is about the case where the user corrects the actual delivery time point), and determine whether the delivery time points fed back by the user are reliable based on the transit time point and the delivery time points. If the time interval between the delivery time point and the passing time point fed back by the user meets the reference time length range, the reference time length range is determined based on the estimated delivery time.
By the method, the reliability of the delivery time can be effectively judged according to two conditions that the passing time point is positioned behind the completion time point of the delivery order and the passing time point is positioned before the completion time point of the delivery order, and the real completion time point of the delivery order can be accurately corrected.
For example, the server 110 may determine the reference duration range based on the following:
the server 110 may obtain the estimated delivery time required from the access gate 122 of the target smart access control device 120 to the destination of the delivery order. And, the server 110 may obtain a time standard deviation corresponding to the estimated delivery time (e.g., a time standard deviation corresponding to 10 minutes of the estimated delivery time is 3 minutes, and a time standard deviation corresponding to 15 minutes of the estimated delivery time is 5 minutes). Then, the server 110 may calculate the reference duration range by the following formula:
t′＝tp+aΔt， (3)
wherein t' is the maximum value of the reference duration range; t is tpRepresenting an estimated delivery time; a is the number of standard deviations, which is determined by the distribution difficulty of the area where the target intelligent access control device 120 is located, and the value is 2-4; Δ t represents the time standard deviation corresponding to the estimated delivery time.
The reference time length range is calculated by using the formula, the distribution difficulty (such as the conditions of more internal buildings, difficulty in finding, route winding, no elevator and the like) of different cells can be considered, the number of different time standard deviations can be determined, the actual condition is better met, and the misjudgment is reduced. For example, although there are many internal buildings and detours (for example, 20 or more), in the case of elevators, the number of time standard deviations takes a value of 3, and many internal buildings and detours (for example, 20 or more), and in the case of no elevator, the number of time standard deviations takes a value of 4.

The Bluetooth identification circuit is formed by combining a Bluetooth chip with necessary peripheral circuits, wherein a Bluetooth 4.2 protocol can be operated in the Bluetooth chip. The specific circuit is shown in fig. 3, and is not described herein again.

Correspondingly, the correspondingly designed display circuit is shown in fig. 5 and 6, and fig. 5 and 6 are different parts of the display circuit, which are combined to obtain the display circuit (details of the circuit are not repeated).
Illustratively, the key unit is an input section of the user, and by pressing a key, a house number, setting of parameters, and the like can be input. Here, the circuit design of the key unit is shown in fig. 7 (the detailed circuit is not repeated).

In this embodiment, an IT972 chip is taken as the main control unit 1211 for example, but the invention should not be construed as being limited to this application, and when a specific chip is selected, other chips satisfying the function may be selected according to actual needs, and the invention is not limited herein.
