Description
Technical Field
[0001] The present application relates to the technical field of automobile anti-theft, and in particular to the technical field of an automobile anti-theft system based on a locator. Background Art
[0002] In the field of car anti-theft, traditional anti-theft systems mainly rely on mechanical locks, electronic alarm devices and remote control units to protect vehicles from theft. These systems usually include sensors installed inside or outside the vehicle (such as vibration sensors, tilt sensors), alarms connected to them, and remote control keys held by the owner.
[0003] Traditional anti-theft systems focus on preventing theft from happening, but provide limited help after the vehicle is stolen. One of the most notable issues is the difficulty in locating the vehicle: once the vehicle is stolen, it can be very difficult to recover it. In addition, most anti-theft system remote control keys only work within a short distance and cannot receive signals beyond a certain range.
[0004] If the remote key is lost or damaged, restoring access to the vehicle may become complicated. In terms of security, although a variety of encryption technologies and rolling code mechanisms have been introduced to prevent copying attacks, there is still a risk of cracking, especially when facing professional thieves. Summary of the invention
[0005] In response to the above problems, this application proposes a car anti-theft system based on a locator. By utilizing the technical features of AirTag, AirTag is embedded into the car anti-theft system to provide users with a more intelligent, safe and convenient solution.
[0006] To achieve the above objectives, this application adopts the following technical solutions:
[0007] A car anti-theft system based on a locator comprises an anti-theft device provided with a power supply circuit, wherein the anti-theft device is built in the car;
[0008] A remote controller provided with a battery, the remote controller being capable of controlling the anti-theft device;
[0009] A first AirTag module is built into the anti-theft device, and the first AirTag module is powered by the power supply circuit.
[0010] This application simplifies the usage process by building the first AirTag module into the anti-theft device and powering it with its power circuit. Car owners do not need to carry additional tracking devices. By using AirTag's precise positioning capabilities and Apple's "Find My" network, the vehicle's location can be easily found even without GPS coverage.
[0011] At the same time, the extensive private network ensures that any Bluetooth-enabled Apple device can anonymously help detect and report the vehicle's location, increasing the possibility of recovering a stolen vehicle.
[0012] In some possible implementations, a second AirTag module is further included in the remote control, and the second AirTag module is powered by the battery.
[0013] By embedding a second AirTag module in the remote control, car owners can not only track the location of the vehicle, but also monitor the status of the remote control in real time. If the remote control is accidentally lost or stolen, the owner can quickly locate and retrieve the remote control through the "Find My" app. This not only protects important control devices, but also prevents potential security risks such as unauthorized vehicle access.
[0014] In addition, the second AirTag module enhances the redundancy and reliability of the overall system. Even if there is a problem with the first AirTag module of the immobilizer, the second AirTag module in the remote control can still provide location information to ensure that the vehicle is always trackable. This dual protection mechanism significantly increases the possibility of recovering the vehicle, especially in an emergency.
[0015] In some preferred embodiments, the first AirTag module and the second AirTag module use Bluetooth low energy communication.
[0016] In some preferred implementations, the Bluetooth low energy uses a 2.4 GHz frequency band.
[0017] In some possible implementations, the anti-theft device further includes a host chip, an output drive circuit, an input conversion circuit, and a wiring harness connection terminal.
[0018] In some possible implementations, the anti-theft device further includes an RF receiving module connected to the host chip, and the RF receiving module is connected to an RF receiving antenna.
[0019] In some possible implementations, the remote controller further includes a remote control encoding chip.
[0020] In some possible implementations, the remote controller further includes an RF transmitting circuit connected to the remote control encoding chip, and the RF transmitting circuit is connected to the PCB antenna. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following examples further illustrate the features of the present application and other related features to facilitate understanding by technicians in the same industry:
[0028] First of all, a car anti-theft device is an electronic device installed on a vehicle to prevent unauthorized persons from starting or moving the vehicle. It is usually installed concealed inside the cockpit or engine compartment. These locations are not only convenient for connecting to the vehicle's electrical system, but also difficult to be easily discovered or damaged by the outside world. In other words, the car's anti-theft device is built into the car.
[0029] Correspondingly, the remote control is a portable electronic device that can control the anti-theft device, allowing the user to control certain functions of the car from a certain distance. It communicates with the car through wireless signals, and the most common application is unlocking and locking the car doors. The remote control can also be used to make the vehicle sound the horn and flash the turn signal to indicate the vehicle's location and facilitate finding the vehicle.
[0030] The AirTag module is an accessory designed for tracking personal items. It has a built-in U1 chip (UltraWideband technology) that can achieve accurate location detection and communicate with other devices using Bluetooth low energy technology. AirTag is designed with privacy and security in mind, using anonymous encrypted broadcast messages to ensure the secure transmission of location information.
[0031] Ultra-Wideband (U1) chip: On compatible Apple devices, such as iPhone 11 and later models, the U1 chip provides more accurate spatial awareness, allowing users to find the exact location of the AirTag through the "Precise Find" feature.
[0032] Bluetooth Low Energy (BLE): AirTag uses BLE technology for short-range wireless communication. This connection method has low power consumption, low cost, and is widely used in various IoT devices. BLE devices can broadcast information and establish connections with other compatible devices without direct pairing or displaying in the Bluetooth device list.
[0033] 2.4GHz band: BLE operates in this frequency band, which is also used for other wireless technologies such as Wi-Fi and Zigbee. This means that AirTag can use ubiquitous infrastructure to communicate but will not interfere with other devices using the same frequency band.
[0034] Find My Network Protocol: This is a private network composed of hundreds of millions of Apple devices, and all participating devices will anonymously help find lost items that join this network. The working principle of this network is based on Bluetooth discovery and location sharing, but it fully respects user privacy and will not disclose any personal information.
[0035] iCloud is a cloud service provided by Apple for data backup, synchronization, and support for services such as Find My. With iCloud, you can log in to other Apple devices or visit icloud.com to find lost items or devices even if your device is not with you.
[0036] AirTag itself does not connect directly to the Internet; instead, it relies on a global private network of nearby Apple devices - the "Find My" network. Any Bluetooth-enabled Apple device can anonymously detect and report the location of nearby AirTags to iCloud without consuming its own battery life. This information is encrypted and only provides location updates to the owner of the AirTag.
[0037] Please refer to Figure 1 and Figure 2 In this case, a car anti-theft system based on a locator includes an anti-theft device 1 provided with a power circuit, which is built into the car as described above, and a remote controller 2 paired with the anti-theft device 1, which can control the anti-theft device 1.
[0038] The anti-theft device 1 includes a host chip, an output drive circuit, an input conversion circuit, and a wiring harness connection terminal. As a connection method with the remote controller 2, an RF receiving module connected to the host chip is provided, and the RF receiving module is connected to an RF receiving antenna.
[0039] The remote controller 2 includes a battery and a remote control coding chip. As a connection method with the anti-theft device 1, an RF transmitting circuit connected to the remote control coding chip is provided inside, and the RF transmitting circuit is connected to a PCB antenna.
[0040] Please refer to reference 3 where the anti-theft device 1 is built into a car, and a locator is built into the anti-theft device 1. The locator built into the anti-theft device 1 is a first AirTag module, and the first AirTag module is powered by the power supply circuit.
[0041] This application simplifies the usage process by building the first AirTag module into the anti-theft device and powering it with its power circuit. Car owners do not need to carry additional tracking devices. They only need to use the car owner's mobile phone 3, using AirTag's precise positioning capabilities and Apple's "Find My" network, so that the vehicle's location can be easily found even without GPS coverage.
[0042] Furthermore, a locator may also be built into the remote controller 2, and the locator built into the remote controller 2 is a second AirTag module, and the second AirTag module is powered by the battery.
[0043] Specifically, the first AirTag module and the second AirTag module use Bluetooth low energy communication. Preferably, the Bluetooth low energy uses the 2.4 GHz frequency band.
[0044] Please refer to Figure 3 and Figure 4 . At this time, first use the search function of the owner's mobile phone 3 iPhone, that is, the "Find My" application to turn on Bluetooth and connect to the first AirTag module. After locking the car and leaving the Bluetooth low energy radiation range of its first AirTag module, such as 50 meters, a positioning location will be marked. The GPS of the owner's mobile phone 3 generates positioning information and saves it in this query function APP, that is, the "Find My" application APP. At this time, the owner's mobile phone 3 is in a state of pre-binding the locator ID.
[0045] If you are looking for a parking space in a large shopping mall where parking instructions are not available, you can first use the "Find My" app on the owner's iPhone to find the location within the Bluetooth low energy radiation range that can connect to the first AirTag module. Then use the beeping sound of the remote control to find the car.
[0046] At the same time, the extensive private network ensures that any Bluetooth-enabled Apple device can anonymously help detect and report the vehicle's location, increasing the possibility of recovering a stolen vehicle.
[0047] Please refer to Figure 5 For example, once the first AirTag module is marked as lost (for example, the user selects "Lost Mode" in the "FindMy" app), it will start sending encrypted Bluetooth signals. These signals contain unique but anonymous information that identifies the AirTag.
[0048] When a nearby passerby's mobile phone 5iPhone or other Bluetooth-enabled Apple devices such as watches, tablets, laptops, etc. (even if they do not belong to the owner of the AirTag) enters the Bluetooth range of the first AirTag module, these devices can detect the Bluetooth signal from the first AirTag module.
[0049] The device that detects the signal of the first AirTag module will transmit the ID and location information of the first AirTag module back to the iCloud cloud through end-to-end encryption 4. At this time, the way to locate this location information may be GPS, signal base station, or IP network point.
[0050] During this process, all data is processed anonymously to ensure that the user's privacy is not violated. Only the registered owner of the first AirTag module, that is, the owner's mobile phone 3 bound to the locator ID, can view this new location information in his "Find My" application. The "Find My" application is the query function APP mentioned above.
[0051] Once the location information is uploaded to iCloud4 and verified successfully, the owner of the first AirTag module will receive a notification informing them that their lost first AirTag module has been found and providing the latest location information.
[0052] Please refer to Figure 6 In another application example, the owner can also track the location of the vehicle and monitor the status of the remote controller 2 in real time through the second AirTag module built into the remote controller 2. If the remote controller 2 is accidentally lost or stolen, the owner can quickly locate and retrieve the remote controller 2 through the "Find My" application, through the mobile phone 5 of passers-by and its new location uploaded to the iCloud cloud 4. This not only protects important control devices, but also prevents potential security risks such as unauthorized vehicle access.
[0053] In addition, the second AirTag module enhances the redundancy and reliability of the overall system. Even if there is a problem with the first AirTag module of the anti-theft device 1, the second AirTag module in the remote control 2 can still provide location information to ensure that the vehicle is always trackable. This dual protection mechanism significantly increases the possibility of recovering the vehicle, especially in an emergency.
[0054] As mentioned above, the present application protects a car anti-theft system based on a locator, and all technical solutions that are the same or similar to the present case should be deemed to fall within the protection scope of the present case.
