Description

Technical Field

[0001] This utility model relates to the field of control technology, and in particular to a traffic control device and a traffic control system. Background Technology

[0002] Access control systems are required in many aspects of daily life and production, such as public transportation and intercity railways. Current access control systems typically include turnstiles equipped with verification devices. Pedestrians must stop at the turnstile to swipe their cards, scan their faces, or scan QR codes before proceeding. If pedestrians find it inconvenient to swipe their cards or scan their faces (e.g., carrying a lot of luggage) or are unfamiliar with these operations (e.g., elderly people unfamiliar with the equipment), they may linger at the turnstiles for longer periods, impacting overall traffic efficiency and increasing the probability of accidents.

[0003] Therefore, contactless access technology has emerged. Contactless access technology is a smart access method that aims to allow users to quickly complete the passage process without having to stop at the gate to swipe cards or scan faces, through technologies such as automatic positioning, automated identity recognition, and payment settlement. Contactless access technology can be applied to transportation, security, and commerce, effectively improving passage efficiency and optimizing user experience. Utility Model Content

[0005] In a first aspect, this utility model provides a passage control device, comprising: an electronic fence detection module for detecting whether an entry into an electronic fence has occurred; a positioning module for communicating with a gate to achieve positioning; and a control module coupled to the electronic fence detection module and the positioning module, wherein the control module controls the positioning module to start working in response to the electronic fence detection module detecting entry into the electronic fence, and controls the positioning module to stop working in response to the electronic fence detection module detecting departure from the electronic fence.

[0006] Optionally, the positioning module includes a UWB chip.

[0007] Optionally, the electronic fence detection module includes a Bluetooth chip.

[0008] Optionally, the Bluetooth chip is a Bluetooth Low Energy chip.

[0009] Optionally, it further includes: a power module for supplying power to the positioning module; wherein, in response to the electronic fence detection module detecting entry into the electronic fence, the control module controls the power module to supply power to the positioning module, and in response to the electronic fence detection module detecting leaving the electronic fence, the control module controls the power module to stop supplying power to the positioning module.

[0010] Optionally, the power module is a rechargeable battery.

[0011] Optionally, it may also include: a first display unit electrically connected to the control module, wherein the control module is further configured to control the display state of the first display unit according to the remaining power of the power module.

[0013] Optional features also include: an NFC chip.

[0014] Optionally, it may also include a security chip, wherein the positioning module is electrically connected to the security chip.

[0015] Secondly, this utility model embodiment provides a passage control system, including: the passage control device described above; and a gate.

[0016] Compared with the prior art, the technical solution of this utility model embodiment has the following beneficial effects:

[0017] In this embodiment of the utility model, the access control device includes: an electronic fence detection module, a positioning module, and a control module. The electronic fence detection module is used to detect whether someone has entered the electronic fence. The positioning module is used to communicate with the gate to achieve positioning. The control module is coupled to the electronic fence detection module and the positioning module. The control module controls the positioning module to start working in response to the electronic fence detection module detecting entry into the electronic fence, and controls the positioning module to stop working in response to the electronic fence detection module detecting exit from the electronic fence.

[0018] In the above solution, an electronic fence detection module is installed in the access control device. When the access control device is detected entering the electronic fence, the positioning module starts working to locate the device. When the access control device is detected leaving the electronic fence, the positioning module stops working. That is, by setting up the electronic fence detection module to start and stop the positioning module, the positioning module only works within the electronic fence area and does not work outside the electronic fence. The solution provided by this embodiment can reduce the power consumption of the access control device.

[0019] Furthermore, the solution provided by this utility model embodiment automatically switches the state of the positioning module based on the detection results of the electronic fence detection module, without requiring manual operation by the user, which helps to improve the user experience.

Using a rechargeable battery as the power module in the above solution helps avoid frequent battery replacements. Attached Figure Description

[0022] Figure 2 This is a schematic diagram illustrating an application scenario of a passage control device according to an embodiment of this utility model.

[0023] Figure 3 This is a schematic diagram of another passage control device in an embodiment of this utility model. Detailed Implementation

[0024] As described in the background section, contactless access technology is a smart access method that uses automatic positioning, automated identity recognition, and payment settlement to allow users to quickly complete the access process without having to stop at the gate to swipe a card or scan their face. In practical applications, users can carry access control devices to achieve contactless access.

[0025] Specifically, the access control device carried by the user can communicate with the turnstile, enabling the turnstile to determine the user's location and obtain user data for authentication. User authentication includes at least one of the following: identity authentication, device authentication, and account authentication. If the user is successfully authenticated, the turnstile allows the user to pass; if the user fails authentication, the turnstile prevents the user from passing. Successfully authenticated users are allowed to enter a specific area.

[0026] In public transportation scenarios (such as buses, subways, high-speed rail, trains, airplanes, and ferries), turnstiles can be used in public transportation scenarios, where users carry access control devices to enter and exit the station.

[0027] In building access control scenarios, turnstiles can be installed in buildings, and users carry access control devices to enter and exit the building.

[0028] In practice, a turnstile can be a device or equipment capable of controlling its own state to allow or restrict user access. For example, a turnstile can be a roller gate, swing gate, or wing gate. As a variation, a turnstile can be an automatic door or similar device.

[0029] In practical implementation, the access control device is a customized electronic device for achieving seamless access. The device may include a housing and a circuit board, with the circuit board containing a UWB chip. The UWB chip communicates with the turnstile to determine the user's location. The positioning module is typically always operational so that the turnstile can locate and authenticate the user before they pass through, avoiding any impact on access efficiency. However, this approach results in a relatively high power consumption for the access control device.

[0030] In view of this, in the embodiment of the present utility model, the access control device includes: an electronic fence detection module, a positioning module, and a control module, wherein the electronic fence detection module is used to detect whether someone has entered the electronic fence; the positioning module is used to communicate with the gate to achieve positioning; the control module is coupled to the electronic fence detection module and the positioning module; the control module controls the positioning module to start working in response to the electronic fence detection module detecting entry into the electronic fence, and controls the positioning module to stop working in response to the electronic fence detection module detecting exit from the electronic fence.

[0031] In the above solution, an electronic fence detection module is installed in the access control device. When the access control device is detected entering the electronic fence, the positioning module starts working to locate the device. When the access control device is detected leaving the electronic fence, the positioning module stops working. That is, by setting up the electronic fence detection module to start and stop the positioning module, the positioning module only works within the electronic fence area and does not work outside the electronic fence. The solution provided by this embodiment can reduce the power consumption of the access control device.

[0032] Furthermore, the solution provided by this utility model embodiment automatically switches the state of the positioning module based on the detection results of the electronic fence detection module, without requiring manual operation by the user, which helps to improve the user experience.

[0033] Reference Figure 1 , Figure 1 This is a structural schematic diagram of a passage control device according to an embodiment of this utility model. Figure 1 As shown, the access control device 10 may include: a positioning module 101, an electronic fence detection module 102, and a control module 103.

[0034] In practical implementation, the positioning module 101 can be used for positioning. Specifically, the positioning module 101 achieves positioning by communicating with a positioning anchor point. For example, the positioning anchor point can be set at the turnstile (…). Figure 1 (Not shown). In specific implementation, based on the communication between the positioning module 101 and the anchor point, the gate can know the location of the access control device 10 based on existing positioning technology.

[0035] In one embodiment, the positioning module 101 may include an ultra-wideband (UWB) chip. Specifically, the UWB chip can transmit data using non-sinusoidal narrow pulses at the nanosecond to microsecond level, and typically uses algorithms such as Time Difference of Arrival (TDoA) to achieve positioning detection. UWB chips have advantages such as high accuracy, short latency, and low power consumption, enabling precise positioning. It should be noted that the positioning module 101 can also employ various other suitable positioning technologies for user positioning detection; this embodiment is not limited to these methods.

[0036] Furthermore, the electronic fence detection module 102 can be used to detect whether the access control device 10 has entered the electronic fence. In other words, the electronic fence detection module 102 can be used to detect whether a user has entered the electronic fence. It should be noted that the electronic fence detection module 102 can use existing electronic fence technology to detect whether someone has entered or left the electronic fence.

[0037] In one embodiment, the electronic fence detection module 102 may include a Bluetooth chip. That is, the electronic fence may be a Bluetooth electronic fence. For example, the Bluetooth chip may be a Bluetooth Low Energy chip.

[0038] In other embodiments, the electronic fence may also be a virtual geofence defined based on other existing technologies.

[0039] In specific implementation, the control module 103 is coupled to the electronic fence detection module 102 to obtain the detection results of the electronic fence detection module 102. Specifically, when the electronic fence detection module 102 detects entry into the electronic fence, it outputs an entry signal to the control module 103; and when it detects leaving the electronic fence, it outputs a leave signal to the control module 103. The control module 103 is also coupled to the positioning module 101 to control the state of the positioning module 101. Specifically, the control module 103 outputs a start signal to the positioning module 101 to trigger its operation, and outputs a stop signal to the positioning module 101 to trigger it to stop operating.

[0040] The control module 103 can control the state of the positioning module 101 based on the detection results of the electronic fence detection module 102.

[0041] More specifically, if the electronic fence detection module 102 detects that the access control device 10 has entered the electronic fence, the control module 103 controls the positioning module 101 to start working. If the electronic fence detection module 102 detects that the access control device 10 has left the electronic fence, the positioning module 101 is controlled to stop working.

[0042] The control module 103 can be a hardware circuit. After receiving the entry signal from the electronic fence detection module 102, the hardware circuit outputs a start signal to the positioning module 101 to trigger the positioning module 101 to start working; otherwise, it outputs a stop signal to the positioning module to stop the positioning module 101 from working.

[0043] Alternatively, the control module 103 can also be implemented based on an existing microcontroller unit (MCU). After receiving the entry signal, the MCU outputs a start signal to the positioning module 101; otherwise, it outputs a stop signal.

[0044] In specific implementations, the access control module 10 may further include: a power supply module ( Figure 1 (Not shown) Among them, the power module can be used to power the positioning module.

[0045] In one possible implementation, if the electronic fence detection module 102 detects that the access control device 10 has entered the electronic fence, the control module 103 can control the power module to electrically connect with the positioning module 101, so that the power module supplies power to the positioning module 101, thereby controlling the positioning module 101 to start working. If the electronic fence detection module 102 detects that the access control device 10 has left the electronic fence, the control module 103 can control the power module to disconnect from the positioning module 101, so that the power module stops supplying power to the positioning module 101, thereby controlling the positioning module 101 to stop working.

[0046] More specifically, the access control device 10 may include a switch, one end of which is connected to the output terminal of the power module, and the other end of which is connected to the power input terminal of the positioning module 101. If the electronic fence detection module 102 detects that the access control device 10 has entered the electronic fence, the control module 103 may control the switch to close, thereby electrically connecting the power module and the positioning module 101. If the electronic fence detection module 102 detects that the access control device 10 has left the electronic fence, the control module 103 may control the switch to open, thereby disconnecting the power module from the positioning module 101.

[0047] In another possible implementation, the positioning module 101 is in a sleep state outside the electronic fence area. The sleep state refers to the positioning module 101 operating in a low-power mode. In the sleep state, the positioning module 101 does not perform positioning but can receive a wake-up signal from the control module 103 to end the sleep state and begin operation at any time. If the electronic fence detection module 102 detects that the access control device 10 has entered the electronic fence, the control module 103 can wake up the positioning module 101, causing it to enter a sleep state from the operating state. If the electronic fence detection module 102 detects that the access control device 10 has left the electronic fence, the control module 103 can control the positioning module 101 to enter a sleep state from the operating state, thereby stopping the positioning module 101 from operating.

[0048] In a variation, if a transaction is detected to be completed or a user remains within the geofence for an extended period of time, the control module 103 can also control the positioning module 101 to stop operating.

[0049] It should be noted that within the scope of the electronic fence, the positioning module 101 is always in an active state to locate the user. However, outside the scope of the electronic fence, the positioning module 101 is in a dormant state or a turned-off state. The turned-off state means that the positioning module 101 is powered off.

[0050] Reference Figure 2 , Figure 2 This is a schematic diagram illustrating an application scenario of a passage control device according to an embodiment of this utility model. The following is in conjunction with… Figure 1 and Figure 2 An exemplary description is provided for the application scenario of a passage control device according to an embodiment of this utility model.

[0051] like Figure 2 As shown in the illustration, in the application scenario of this utility model embodiment, a turnstile is provided in the user's direction of travel. This utility model embodiment uses a turnstile as an example for description. In practical applications, the turnstile can also be an automatic door, an automatic fence, or other similar equipment.

[0052] like Figure 2 As shown, the turnstile may include a main body 121 and a blocking part 122. For example, the main body 121 may include positioning anchor points. The blocking part 122 can be used to restrict user passage. Specifically, if the blocking device 122 is open, the user can pass through the turnstile; if the blocking device 122 is closed, the user cannot pass through the turnstile.

[0053] As the user moves along the direction of travel, if the electronic fence detection module 102 detects that the user has entered the electronic fence 11, the control module 103 controls the positioning module 101 to start working. The positioning module 101 can be used to determine the user's specific location within the electronic fence.

[0054] Furthermore, if a user enters the authentication area, the access control device can establish a secure data exchange channel with the turnstile, allowing the turnstile to read the user data stored in the access control device. The turnstile then authenticates the user based on the read user data. If authentication is successful, the turnstile's control barrier opens, and the user can continue moving in the direction of travel. If authentication fails, the turnstile's control barrier remains closed, and the user is prevented from passing through the turnstile.

[0055] Furthermore, as the user moves forward, if the system detects that the user has entered the billing area, it can determine that the user has passed through the gate, and thus billing can be performed on the user. It should be noted that in practical applications, the billing area is optional.

[0056] Furthermore, as the user moves, if the system detects that the user has left the electronic fence, the control module 103 can control the positioning module 101 to stop working.

[0057] Reference Figure 3 , Figure 3 This is another access control device in the embodiments of this utility model. For example... Figure 3 As shown, compared to Figure 2 The access control device shown Figure 3 The access control device 10 shown also includes a power module 104, a security chip 105, and a near field communication (NFC) chip 106.

[0058] Specifically, the access control device 10 may further include a power module 104. The power module 104 can be used to supply power to the modules in the access control device 10.

[0059] In one possible implementation, power module 104 can be a rechargeable battery. For example, power module 204 can be a polymer lithium battery, but it is not limited to this.

[0060] In another possible implementation, the power module 104 can be a non-rechargeable battery. For example, the power module 104 can be a coin cell battery.

[0061] For more information about power module 104, please refer to the above text. Figure 1 The relevant descriptions will not be repeated here.

[0062] Furthermore, the access control device 10 may also include a security chip 105, which can be electrically connected to the positioning module 101. The security chip 105 can be used to encrypt the data transmission of the access control device 10 to ensure information security.

[0063] In addition, the security chip 105 can be electrically connected to the power module 104, which can supply power to the security chip.

[0064] Furthermore, the access control device 10 may also include an NFC chip 106. Specifically, while the positioning module 101 is in a closed or dormant state, the user can also use the NFC chip 106 in the access control device 10 to swipe their card for passage. Alternatively, if the gate does not support contactless passage, the user can use the NFC chip 106 in the access control device 10 to swipe their card for passage.

[0065] In one possible implementation, the access control device 10 may further include a first display unit (not shown), which may be electrically connected to the control module 103. The control module 103 may control the display state of the first display unit based on the remaining power of the power module 104.

[0066] For example, if the remaining power of the power module 104 is greater than the first threshold, the color of the first display unit is green. If the remaining power of the power module 104 is less than or equal to the first threshold, the color of the first display unit is red. Through the display status of the first display unit, users can conveniently and promptly know the power status of the power module 104 so that they can charge or replace it in time when the power is low.

[0067] In one possible implementation, the access control device 10 may further include a second display unit (not shown), which may be electrically connected to the control module 103. The control module 103 may control the display state of the second display unit according to the operating state of the positioning module 101.

[0068] For example, if the positioning module is active, the second display unit can be controlled to emit light. If the positioning module is off or in sleep mode, the second display unit can be controlled to remain off. Through the display status of the second display unit, users can intuitively understand the working status of the positioning module 101. If the positioning module 101 malfunctions during passage, users can promptly switch to NFC chip-based card payment to avoid impacting passage efficiency.

[0069] As described above, the access control device in this article is an electronic device for achieving seamless access. The access control device may include a housing and a circuit board, on which the aforementioned positioning module, electronic fence detection module, control module, power module, security chip, and NFC chip are mounted. For example, the access control device can also be integrated into general electronic devices. For instance, the access control device can be integrated into mobile phones, wearable devices, etc.

[0070] This utility model embodiment also provides a passage control system, which may include: a passage control device and a turnstile. Specific details regarding the passage control device and the turnstile can be found in the above description and will not be repeated here.

[0071] As mentioned above, the electronic fence detection module may include a Bluetooth chip, and the access control device may be a transportation card. The issuer of the transportation card can also configure the transportation card data via the Bluetooth chip to achieve personalization and instance functionality. Furthermore, the Bluetooth chip can also be used to connect to user terminals to update the firmware or application data of the access control device.

[0072] As mentioned above, the positioning module may include a UWB chip. In practical applications, the first and second turnstiles in the same specific area are usually close to each other. The first turnstile is used to restrict users from entering the specific area, and the second turnstile is used to restrict users from leaving the specific area. Taking a subway as an example, the turnstiles for entering the station and the turnstiles for exiting the station are close to each other.

[0073] Because the first and second turnstiles in the same specific area are usually close to each other, the UWB chip in the access control device carried by a user about to enter the specific area may connect to the positioning anchor point in the second turnstile. As a result, the first turnstile cannot determine the user's location and cannot perform authentication operations. Alternatively, the UWB chip in the access control device carried by a user about to leave the specific area may connect to the positioning anchor point in the first turnstile. Consequently, the second turnstile cannot determine the user's location and cannot perform authentication operations. In these cases, the incorrect anchor point connection will prevent the user from passing through normally.

[0074] Therefore, upon detecting entry into the electronic fence, the control module sets the operating mode of the UWB chip. For example, if it detects that the device is inside the electronic fence detection module, the control module determines whether the UWB chip is connected to the entrance gate or the exit gate.

[0075] Specifically, the access control device may have a card status indicator, and the positioning anchors in the passage blocking device have type identifiers. The type identifiers may include a first type identifier and a second type identifier. Specifically, the positioning anchors in the passage blocking device used to restrict entry into a specific area have a first type identifier, and the positioning anchors in the passage blocking device used to restrict exit from a specific area have a second type identifier; the first type identifier and the second type identifier are different.

[0076] Furthermore, the card status identifier includes a first status identifier and a second status identifier, which are different. The first status identifier corresponds to a first type identifier, and the second status identifier corresponds to a second type identifier.

[0077] The default state identifier of the UWB chip is the first state identifier. After a user enters the geofence, the UWB chip starts working and can communicate with the positioning anchor points. The data sent out by the UWB chip includes the first state identifier. Correspondingly, the positioning anchor point that receives the state identifier from the UWB chip performs an identifier matching. If the positioning anchor point's type identifier is the first type identifier, the positioning anchor point communicates with the UWB chip for positioning and authentication. If the positioning anchor point's type identifier is the second type identifier, the positioning anchor point does not communicate with the UWB chip.

[0078] Furthermore, after the UWB chip enters a specific area through the channel blocking device, the card status identifier of the UWB chip is modified to the second status identifier.

[0079] Furthermore, when a user is about to leave a specific area, after the user enters the electronic fence, the UWB chip begins to operate and can communicate with the positioning anchor point. The data sent out by the UWB chip includes a second status identifier. Correspondingly, the positioning anchor point receiving the UWB chip's status identifier performs an identifier match. If the positioning anchor point's type identifier is the second type identifier, then the positioning anchor point communicates with the UWB chip for positioning and authentication. If the positioning anchor point's type identifier is the first type identifier, then the positioning anchor point does not communicate with the UWB chip. Furthermore, after the UWB chip blocks the device from leaving the specific area through the channel, the UWB chip's card status identifier is changed to the first status identifier.
