The server 110 in this embodiment may be understood as a platform side (e.g. "X group"), and the intelligent terminal 130 of the distribution person may be understood as a distribution person side; the intelligent terminal 130 may be a smart phone, a tablet computer, etc. bound by the distribution personnel, and of course, the intelligent terminal 130 of the internal personnel may be understood as a user side, and is a smart phone, a tablet computer, etc. bound by the user; the intelligent access control devices 120 may be understood as security parties, and each intelligent access control device 120 corresponds to an area (such as a district interior, an office building interior, etc.), and since a district may have a plurality of different doors, different intelligent access control devices 120 may correspond to the same area, which is not limited herein. For convenience of description, the embodiment uses an intelligent access control device 120 as an example, but should not be construed as limiting the application.
For example, the server 110 may be configured to assign a delivery order to the intelligent terminal 130 bound to the delivery person, and obtain the MAC address of the intelligent terminal 130, and issue the delivery order as a temporary MAC address to the target intelligent access control device 120, where the destination of the delivery order is located in the area of the target intelligent access control device 120, and the delivery order must be 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 area, and thus, the temporary MAC address is issued to the target intelligent access control device 120, which may be a plurality of intelligent access control devices 120 in the area, which is not limited herein.
For example, the target intelligent entrance guard control apparatus 120 may include an entrance guard control module 121 and an entrance guard gate 122, and the entrance guard control module 121 includes a main control unit 1211, a wireless communication unit 1213, an upper communication unit 1212, and a driving unit 1214. The main control unit 1211 is configured to perform a wireless communication-based intelligent access control method, so as to implement the function of the wireless communication-based intelligent access temporary pass system 100.
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.
After the server 110 obtains the MAC address of the intelligent terminal 130 bound to the dispatcher, and issues the MAC address as a temporary MAC address to the target intelligent entrance guard control device 120, the main control unit 1211 of the entrance guard control module 121 in the target intelligent entrance guard control device 120 may execute step S10.
Step S10: the method comprises the steps of obtaining a temporary MAC address sent by a server and received by an 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 the MAC address of an intelligent terminal corresponding to a delivery order distributed by the server, the destination of the delivery order is located in an area where the intelligent access control device is located, and the intelligent terminal is an intelligent terminal bound by a delivery 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, and 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 the external intelligent terminals 130 (the external intelligent terminals 130 are distinguished from the previous intelligent terminals 130 in terms of names, and the external intelligent terminals 130 may be intelligent terminals 130 of residents in the cell, or may be intelligent terminals 130 of distribution personnel, or may be intelligent terminals 130 of other pedestrians) in real time, and establish wireless communication with the intelligent terminals 130, acquire the device MAC addresses of the intelligent terminals 130, and detect the signal strength when communicating with the wireless communication unit as the device information corresponding to the intelligent terminals 130. Then, the main control unit 1211 may perform step S20.
Step S20: and acquiring the equipment information received by the wireless communication unit, wherein the equipment information is acquired by the wireless communication unit through wireless communication with an external intelligent terminal, and the equipment information comprises an equipment MAC address and signal strength of the external intelligent terminal.
In the present embodiment, the main control unit 1211 may acquire device information (including a device MAC address and signal strength of the external smart terminal 130) received by the wireless communication unit 1213.
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: judging whether the equipment MAC address belongs to a pre-stored MAC address, 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 intelligent terminal 130 used by the resident is pre-stored, as the permanent MAC address, and of course, a conventional modification operation such as changing, deleting, etc. may be performed) and a temporary MAC address (for example, the MAC address of the intelligent terminal 130 bound by the dispatcher is pre-stored, as the temporary MAC address).
The main control unit 1211 may determine whether the device MAC address belongs to the pre-stored MAC address by determining whether the device MAC address is pre-stored by the main control unit 1211 through a table lookup matching method.
For the case that the device MAC address does not belong to the pre-stored MAC address, the main control unit 1211 may determine that the device MAC address does not belong to the pre-stored MAC address without performing other operations.
The main control unit 1211 may perform step S40 for the case where the device MAC address belongs to a pre-stored MAC address.

In this embodiment, the main control unit 1211 may determine the interval distance based on the signal strength, and generate control information when the interval distance meets the distance condition, and send the control information to the driving unit 1214, so that the driving unit 1214 controls the gate 122 to open based on the control information.
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 erase for the permanent MAC address. In order to ensure the reliability of the security system, a corresponding elimination operation is required for the temporary MAC address. Accordingly, 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 the 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.
By acquiring and pre-storing the temporary MAC address (the MAC address of the intelligent terminal 130 corresponding to the delivery order allocated by the server 110) issued by the server 110, adding the temporary MAC address to a pre-stored MAC address list, and by acquiring the device information (including the device MAC address and the signal strength of the external intelligent terminal 130) received by the wireless communication unit 1213; then judging whether the equipment MAC address belongs to a pre-stored MAC address (comprising a permanent MAC address and a temporary MAC address); if the device MAC address belongs to the pre-stored MAC address, the separation distance is determined based on the signal strength, and when the separation distance meets the distance condition, control information is generated and sent to the driving unit 1214, so that the driving unit 1214 controls the gate 122 to open based on the control information. Further, if the device MAC address belongs to the temporary MAC address, after the control information is generated, the device MAC address is removed from the pre-stored MAC address list. In this way, a temporary pass instruction can be established for the distribution personnel, and the MAC address of the intelligent terminal 130 bound by the distribution personnel is temporarily pre-stored, so that the distribution personnel can use the MAC address of the intelligent terminal 130 bound by the distribution personnel to pass through the intelligent access control device 120. After the distribution personnel enter, the equipment MAC address (namely the MAC address of the intelligent terminal 130 bound by the distribution personnel) can be eliminated from the pre-stored MAC address list, so that before the distribution personnel receives a distribution order in the area next time, the distribution personnel cannot utilize the bound MAC address of the intelligent terminal 130 again through the intelligent access control device 120, the safety of the district (or building such as office building) is greatly improved, the convenience of the personnel in the district can be ensured, and the entrance is not required to be taken. In addition, the mode can realize contactless access control verification, does not need people (inside personnel, using a permanent MAC address; distribution personnel, using a temporary MAC address) to perform close-range manual card swiping verification, is very convenient, does not need to enter personal privacy information such as faces and fingerprints, and improves the safety of the personal information. Overall, the scheme can realize that users and distribution personnel can pass the gate entrance guard machine without operation (time can be saved for the distribution personnel), and the hardware requirement on the intelligent gate entrance guard control device 120 is lower, so that the manufacturing cost can be reduced.
In this embodiment, the wireless communication unit 1213 may be a bluetooth module, and the corresponding signal strength is an RSSI (Received Signal Strength Indication ) value, and then the main control unit 1211 may determine the interval distance in the following manner:
for example, the master unit 1211 may substitute the RSSI value into the following formula:
wherein d represents a separation distance; RSSI represents an RSSI value; a represents a signal strength when the transmitting end is separated from the receiving end by 1 meter, that is, a signal strength value when the external intelligent terminal 130 is separated from the wireless communication unit 1213 by 1 meter; n represents an environmental attenuation factor; abs () represents an absolute value function.
Thus, the separation distance d can be calculated by the formula (1).
By adopting the bluetooth module as the wireless communication unit 1213, the intelligent terminals 130 near the intelligent access control device 120 (the access control module 121 and the access gate 122) can be effectively detected, and bluetooth communication can be established to obtain the interval distance between the intelligent terminals 130, so as to determine whether to open the access gate 122. The calculation mode 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 transmitting it 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 gate 122, where the current state is an open state or a closed state, the open state indicates that the gate 122 is in a process of being opened or a state of being kept open, and the closed state indicates that the gate 122 is in a process of being closed or a state of being kept closed.
The main control unit 1211 may determine whether the interval distance is within the first distance range when the current state is the off state, and generate control information to transmit to the driving unit 1214 when the interval distance is within the first distance range.
The main control unit 1211 may determine whether the interval distance is within the second distance range when the current state is the on state, and generate control information to transmit to the driving unit 1214 when the interval 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 criteria are set for different states (on state or off state) of the current state of the gate 122: for the case that the gate 122 is in the closed state, by judging whether the interval distance is within the first distance range, and when the interval distance is within the first distance range, generating control information and sending the control information to the driving unit 1214; for the case that the gate 122 is in the open state, it is determined whether the interval distance is within a second distance range, and when the interval distance is within the second distance range, control information is generated and sent to the driving unit 1214, where a maximum distance value of the second distance range is greater than a maximum distance value of the first distance range. The situation can fully consider that when the gate 122 is in a closed state, the gate is only required to be normally opened, and the time is less; when the gate 122 is in an open state, the following person is usually caused to accelerate the entry of the foot, so that the situation such as collision, falling and the like is easy to occur. If the door control is judged to be opened according to the normal judgment distance (the first distance range), the door control gate 122 is closed, and the following personnel enter the first distance range to be opened, so that the door control gate 122 is frequently opened and closed, the energy is wasted, the aging of the door control gate 122 is easier to cause, and psychological tension is caused to the following personnel. Therefore, when the gate 122 is in the open state, different judging standards are adopted when the gate 122 is in the closed state, so that more sufficient time is reserved for later personnel, the conditions of collision, falling and the like caused by the urgent running of the personnel are avoided as much as possible, energy sources can be saved, and the aging of the gate 122 is slowed down.
Illustratively, the interval between the entrance and the exit of the gate 122 is greater than a set distance y meters (e.g., greater than 5 meters, greater than 10 meters, etc., and 5 meters are an example), and the time required for the gate 122 to change from open to closed is t seconds (e.g., 3 seconds, 5 seconds, etc., and 3 seconds are an example).
Then the maximum value of the first distance range is x 1 Meter (e.g. 2 meter, 3 meter, etc., preferably 2 meter), the maximum value of the second distance rangeIs x 2 Meters (e.g., 5 meters, 8 meters, etc.), wherein the set distance y is greater than the maximum x of the second distance range 2 And x is 1 And x 2 The following conditions are satisfied:
x 1 +1.5t≥x 2 ≥x 1 +0.5t， (2)
wherein 0<t is less than or equal to 5.
Determining the maximum value of the first distance range as x in this way 1 And the maximum value of the second distance range is x 2 And the maximum value x of the second distance range is determined in consideration of the time t seconds required for the gate 122 to switch from open to closed 2 Is a value of (a). The coefficient 0.5 is a low value and can be regarded as a speed of a person walking normally in an area between the first distance range and the second distance range (in the sensing range of the wireless communication unit 1213), and the coefficient 1.5 is a high value and can be regarded as a speed of a rider (e.g., a delivery person) and a driver (e.g., a resident) in an area between the first distance range and the second distance range (in the sensing range of the wireless communication unit 1213), so that appropriate coefficient values can be selected and set according to different cell conditions (e.g., whether the rider can pass through, whether the driver can pass through, an actual traffic road condition in an area between the first distance range and the second distance range, etc.). And, the maximum value of the second distance range is located in the effective communication range (usually 10 meters or more) of the bluetooth module (or the common wireless communication unit 1213 such as WIFI) so as to ensure the feasibility of the scheme.
In this embodiment, for the case where the device MAC address belongs to the temporary MAC address, after generating the control information, the main control unit 1211 may further record a passing time point of generating the control information, 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 delivery person has a non-loyalty of clicking in advance to complete the delivery order based on the traffic time point and the completion time point of the delivery order corresponding to the MAC address of the device.
The passing time point of the intelligent access control device 120 in the area can be accurately obtained by generating the passing time point of the control information, so that the passing time point of the intelligent access control device 120 in the area can be used as a powerful basis for judging whether the distribution personnel has the non-trustworthiness of clicking in advance to finish the distribution order, the general situation that the distribution personnel clicks in advance to finish the order when not delivering the goods can be effectively checked, benefits of users (such as right of time and the like for guaranteeing the product) can be protected as much as possible, air in the whole distribution industry can be improved in a supervision mode, the quality of the distribution personnel can be improved, the user viscosity can be improved, and multiparty win-over of the platform side (the user satisfaction degree is improved), the user side (the enjoyment of a convenient life style), the distribution personnel side (the benefits of eliminating the distribution personnel with low quality and guaranteeing the high quality distribution personnel) and the security party (the reliability of the security system can be guaranteed, and the manpower and material resources cost on the suspected person can be reduced).
In this embodiment, the specific manner of the master control unit 1211 removing the device MAC address from the pre-stored MAC address list may be: acquiring a current time point; judging whether the interval between the current time point and the passing time point reaches a set duration, wherein the value range of the set duration is 30-150 seconds; and eliminating the equipment MAC address from the pre-stored MAC address list after the interval between the current time point and the passing time point reaches the set duration.
In this implementation, after the interval between the current time point and the passing time point reaches the set duration (the value range is 30-150 seconds), the device MAC address is eliminated from the pre-stored MAC address list, so that a certain time can be reserved for the distribution personnel, and the distribution personnel needs to stop the electric motorcycle at the roadside (possibly in the second distance range or even in the first distance range) because some cells do not allow the electric motorcycle to pass, and take out the article from the trunk through the gate 122. Therefore, the reserved time can reserve reasonable time for the operation of the distribution personnel, and the method has more practicability.
In addition, for the server 110, it may be determined whether the distribution personnel has a dishonest act of clicking in advance to complete the distribution order, which may be specifically performed in the following manner:
The server 110 may determine whether the transit time point is located 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 non-trustworthiness of clicking in advance to complete the delivery order (because the delivery person has not yet reached the gate 122 of the target intelligent gate control device 120). The server 110 may then obtain the estimated delivery time required from the gate 122 of the target intelligent gate control device 120 to the destination of the delivery order (the average time may be obtained from a large amount of past delivery data as the estimated delivery time, although other ways may be selected to obtain the estimated delivery time, which is not limited herein), and correct the actual completion time of the delivery order based on the transit time 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 point of the user feedback of the delivery order (some delivery orders, the user will actively correct the actual delivery time point, some delivery orders, the user will not actively correct, and the user will not actively correct the actual delivery time point will be discussed herein), and determine whether the delivery time point of the user feedback is reliable based on the transit time point and the delivery time point. If so, the server 110 may correct the actual completion time of the delivery order based on the delivery time, where the user-fed delivery time is determined to be reliable when the interval between the delivery time and the transit time corresponds to a reference time range, and the reference time range is determined based on the estimated delivery time.
By the method, the reliability of the delivery time can be effectively judged for the two cases that the passing time point is positioned after 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 server 110 may obtain the estimated delivery time required from the gate 122 of the target intelligent gate 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 (for example, 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). The server 110 may then calculate the reference time range by the following formula:
t′＝t p +aΔt， (3)
wherein t' is the maximum value of the reference duration range; t is t p Representing estimated delivery time; a is the standard deviation number, 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; Δt represents the time standard deviation corresponding to the estimated delivery time.
The reference duration range is calculated by using the formula, and different time standard deviation numbers can be determined by considering the distribution difficulty (such as the conditions of multiple buildings in the interior, difficulty in finding, routing, no elevator and the like) of different cells, so that the method is more in line with the actual conditions and reduces misjudgment. For example, although there are many internal buildings and routes (for example, 20 or more), the time standard deviation value is 3 in the case of an elevator, and 4 in the case of no elevator.
The above description is directed to the temporary access control system 100 based on wireless communication and the intelligent access control method based on wireless communication applied to the main control unit 1211 in this scheme, and in order to facilitate further understanding of this scheme, the following description is directed to the hardware design of the access control module 121 in the intelligent access control device 120 provided in this scheme.
The wireless communication unit 1213 is mainly used for performing wireless communication with the intelligent terminal 130 in the sensing range, so that a bluetooth module, a WIFI module, or the like may be selected as the wireless communication unit 1213, and a chip integrated with a bluetooth or WIFI function may be selected as the main control unit 1211, so that the main control unit 1211 and the wireless communication unit 1213 are integrated, which is not limited herein. In this embodiment, bluetooth is taken as an example, but this should not be construed as limiting the present application.
For example, when a bluetooth module is selected as the wireless communication unit 1213, the corresponding bluetooth identification circuit may refer to fig. 3, and serial ports are used between the bluetooth identification circuit and the main control unit 1211 for communication, where the bluetooth identification circuit may use an external antenna to increase the identification distance. The Bluetooth identification circuit is formed by combining a Bluetooth chip with necessary peripheral circuits, wherein Bluetooth 4.2 protocol can be operated in the Bluetooth chip. The specific circuit is shown in fig. 3, and will not be described here again.
The gate 122 is internally provided with a relay, and the main control unit 1211 can control the opening and closing of the relay through a triode. And the control line of the door lock in the gate access 122 is connected to the normally open port and the public port of the relay, when the control pin of the relay has a signal, the relay is attracted, the control line of the door lock is electrified, the gate access 122 is opened, and the gate access control circuit (driving unit 1214) correspondingly designed is shown in fig. 4 (the specific circuit is not repeated). Of course, in other modes, the gate 122 may also be a sliding gate, and when the gate 122 is opened, the driving motor drags the gate to slide, so as to open the gate.
In this embodiment, the access control module 121 may further be provided with a corresponding display unit, a key unit, and the like, which is not limited herein.
The display screen of the display unit is responsible for realizing the prompt related to operation or intercom on one hand, setting the prompt of operation on the other hand, and displaying the MAC address of the searched Bluetooth device. Correspondingly, the display circuits of the corresponding designs are shown in fig. 5 and fig. 6, and fig. 5 and fig. 6 are different parts of the display circuits, and the display circuits are obtained by combining (specific circuits are not described in detail).
The key unit is an input portion of a user, by which a room number, setting of parameters, and the like can be input, for example. Here, the circuit design of the key unit is shown in fig. 7 (specific circuits are not described in detail).
Based on this, since the main control unit 1211 is required to have a large number of interfaces (since, in addition to the core function, some other auxiliary functions such as a key unit, a display unit, a communication unit, etc. are required to be satisfied), the functions of the main control unit 1211 are satisfied.
For example, in this embodiment, an IT972 chip is selected as the main control unit 1211, but the application should not be considered as being limited, and other chips meeting functions may be selected according to actual needs during the specific chip type selection, which is not limited herein. When the IT972 chip is used as the main control unit 1211, the corresponding design circuit is shown in fig. 8 and 9 (specific circuits are not described in detail).

Further, if the device MAC address belongs to the temporary MAC address, after the control information is generated, the device MAC address is removed from the pre-stored MAC address list. In this way, a temporary pass instruction can be established for the distribution personnel, and the MAC address of the intelligent terminal 130 bound by the distribution personnel is temporarily pre-stored, so that the distribution personnel can use the MAC address of the intelligent terminal 130 bound by the distribution personnel to pass through the intelligent access control device 120. After the distribution personnel enter, the equipment MAC address (namely the MAC address of the intelligent terminal 130 bound by the distribution personnel) can be eliminated from the pre-stored MAC address list, so that before the distribution personnel receives a distribution order in the area next time, the distribution personnel cannot utilize the bound MAC address of the intelligent terminal 130 again through the intelligent access control device 120, the safety of the district (or building such as office building) is greatly improved, the convenience of the personnel in the district can be ensured, and the entrance is not required to be taken.
