Description
Technical Field
[0001] This invention belongs to the field of personal item security technology, specifically a portable multi-device minimalist hardware collaborative security system. Background Technology
[0002] With the diversification of public security scenarios and the continuous increase in the value of residents' personal property, the demand for theft prevention and loss prevention of personal items such as wallets, documents, mobile terminals, and portable bags is becoming increasingly urgent. The market has put forward higher requirements for the reliability, ease of use, synergy, and anti-interference of personal security products.
[0003] Currently, most personal anti-theft and anti-loss security products are designed with software as the core and wireless communication as the core architecture. They generally rely on wireless transmission methods such as Bluetooth and WiFi, as well as mobile apps and processor programs to achieve device pairing, status monitoring, and alarm control. In practical applications, they have many insurmountable technical defects and cannot meet users' needs for highly reliable personal security in all scenarios. These products are not only highly dependent on software and wireless communication, making them susceptible to failure due to device status and external environment, and have poor anti-interference capabilities, but also have cumbersome configuration processes and high usage thresholds, making it difficult for the elderly and children to operate independently. At the same time, they lack hardware-level alarm priority management mechanisms, which can easily lead to conflicts between multiple device alarms and delays in handling high-risk scenarios. Furthermore, they lack physical anti-tampering and anti-hacking designs, making them easy to disassemble and block signals, posing significant security risks. In addition, the wireless module and processor need to work continuously, resulting in high power consumption and insufficient battery life. Moreover, function upgrades and fault repairs all rely on software updates, leading to high daily use and maintenance costs. Summary of the Invention
[0004] The purpose of this invention is to provide a portable, multi-device, minimalist hardware collaborative security system to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable multi-device simplified hardware collaborative security system, comprising a single master terminal and multiple heterogeneous slave terminals;
[0006] The main control terminal has a built-in pure hardware control unit, frequency identification unit, priority decision unit, alarm unit, independent power supply module and anti-tampering unit. The frequency identification unit is a hardware resonant circuit with at least one set of fixed resonant frequencies, and the resonant frequencies are fixed in the frequency identification unit by fuses.
[0007] The heterogeneous slave terminal includes at least one of the following: a passive card for personal use, a magnetic terminal for bags, and a mobile phone patch terminal. Each of the heterogeneous slave terminals has a built-in physical monitoring unit and a signal interaction unit. The heterogeneous slave terminal and the master control terminal establish a primary status monitoring link through a contact-type physical connection or magnetic field coupling to achieve primary status monitoring.
[0008] The frequency identification unit acquires the signals of the heterogeneous slave terminals through frequency resonant coupling and automatically identifies the type of the heterogeneous slave terminals. The priority decision unit is built based on pure logic gate circuits and is used to realize fixed priority alarm decision. When the first-level status monitoring link is in an abnormal state of disconnection, sudden change, removal, cutting or disconnection, the pure hardware control unit controls the alarm unit to trigger the priority alarm corresponding to the heterogeneous slave terminal within a preset time threshold after the abnormal state occurs.
[0009] The connection method includes at least one of magnetic field coupling, magnetic connector, conductive wire, pull rope, steel wire rope, conductive clamp, normally closed switch, and tripping structure; and the frequency identification unit collects the signal of the heterogeneous slave terminal through mirror resonant coupling to achieve automatic identification and signal authenticity verification, and the decision logic of the priority decision unit is linked with the signal authenticity verification result.
[0010] As a further preferred embodiment of this technical solution: the priority decision unit is constructed using a NAND gate chip and a hardware self-locking circuit. The rule for the fixed priority alarm decision is that different resonant frequencies correspond to different alarm priorities, wherein the priority of the close-fitting anti-pickpocketing alarm corresponding to the low frequency band is higher than the priority of the close-fitting anti-drag alarm corresponding to the mid frequency band; the priority of the close-fitting anti-drag alarm corresponding to the mid frequency band is higher than the priority of the mobile phone anti-forgotten alarm corresponding to the high frequency band; when a high-priority alarm is triggered, the priority decision unit automatically blocks the low-priority alarm signal.
[0011] The fixed priority alarm decision rules are embedded in the NAND gate chip and the self-locking circuit through hardware wiring and cannot be modified by software, external configuration signals or parameter adjustments.
[0012] As a further preferred embodiment of this technical solution: the main control terminal also has a built-in wireless communication module. When the primary status monitoring link fails to work properly due to physical disconnection, magnetic field coupling failure, or distance exceeding a preset range, the pure hardware control unit controls the wireless communication module to be automatically activated. The wireless communication module performs secondary anti-forgotten monitoring and triggers secondary alarms based on the wireless signal strength being lower than a preset signal strength threshold or the wireless connection being disconnected. Moreover, the secondary alarms and the priority alarms triggered by the primary status monitoring link are independent of each other and do not interfere with each other.
[0013] As a further preferred embodiment of this technical solution: the wireless communication module is at least one of a Bluetooth BLE module, a UWB module, and an RF module, and the wireless communication module is activated only when the first-level status monitoring link fails, and is in a dormant state in other states.
[0014] As a further preferred embodiment of this technical solution: the anti-tampering unit includes a metal shielding layer and an anti-tamper trigger normally closed switch. The metal shielding layer covers the inner side of the housing of the main control terminal, and the anti-tamper trigger normally closed switch is connected in series in the main circuit of the main control terminal. When the housing of the main control terminal is disassembled, the anti-tamper trigger normally closed switch triggers a disassembly signal. The pure hardware control unit controls the alarm unit to trigger a first-level alarm according to the disassembly signal and cuts off the power supply circuit of the wireless communication module.
[0015] As a further preferred embodiment of this technical solution: the master control terminal and each of the heterogeneous slave terminals are provided with a standardized hardware expansion interface, which is a pin-type socket or a magnetic contact, and is used to connect external functional expansion modules.
[0016] As a further preferred embodiment of this technical solution: the external functional expansion module is at least one of a photosensitive monitoring module, a temperature sensing early warning module, and an active deterrence module; the pure hardware control unit controls the alarm unit to trigger an alarm based on the working signal transmitted by the external functional expansion module, or directly activates the external functional expansion module to perform deterrence actions such as flashing, releasing dye, or spraying.
[0017] As a further preferred embodiment of this technical solution: the activation signal of the active deterrence module is a combination of the rapid disconnection signal and the impact signal collected by the primary state monitoring link.
[0018] As a further preferred embodiment of this technical solution: the main control terminal has a physical button on its housing surface, which is used to send a global mute command or a forced reset command to the pure hardware control unit; at least one of the heterogeneous slave terminals supports dual-mode adaptation of passive mode or active mode, wherein the heterogeneous slave terminal in passive mode achieves power supply and signal recognition synchronously through mirror magnetic field coupling with the main control terminal, without the need for an additional power supply module.
[0019] As a further preferred embodiment of this technical solution: the independent power supply module built into the main control terminal is a long-lasting power supply module, which can continuously power the device for several months in a preset working mode; the frequency identification unit realizes automatic resonant coupling, terminal identification and automatic arming within a preset time when the heterogeneous slave terminal approaches its preset coupling distance range.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] 1. In this invention, the system adopts a pure hardware architecture without software, MCU / CPU, program, or APP, avoiding problems such as system crashes, program failures, signal interference by jammers, Bluetooth / WIFI disconnection, and permission restrictions in traditional solutions; the physical main monitoring link response delay is ≤0.1 seconds, which can accurately respond to instant theft behaviors such as pickpockets pulling away instantly, dragging violently, or cutting, and can be adapted to various extreme security scenarios, achieving zero missed alarms and zero delay.
[0022] 2. In this invention, the system achieves automatic identification, type differentiation and automatic arming of heterogeneous slave terminals through mirror resonant coupling. No Bluetooth pairing, software settings, manual configuration or any other operation is required. It enters the ready-to-arm state as soon as it is powered on. Arming can be completed when the slave terminal is brought close to the master terminal at a preset distance. It can be used without barriers by the elderly, children and non-technical people.
[0023] 3. In this invention, the alarm priority is permanently fixed through the wiring of NAND gate chips and hardware self-locking circuits, and cannot be modified by software, external configuration signals or parameter adjustments. Furthermore, when a high-priority alarm is triggered, it will automatically block low-priority signals, thus solving the conflict problem of simultaneous alarms in traditional multi-device security solutions from a physical perspective.
[0024] 4. In this invention, the system incorporates a triple hardware anti-tampering structure: a built-in copper metal shielding layer, an anti-tamper normally closed switch, and fuse parameter solidification. The metal shielding layer effectively resists strong external electromagnetic interference, ensuring stable resonance identification and signal transmission. The anti-tamper normally closed switch is connected in series with the main alarm circuit; removing the casing triggers the highest priority alarm and cuts off the power supply to the wireless module, preventing malicious disassembly. Core parameters such as resonant frequency, alarm priority, and distance threshold are solidified by a one-time fuse, making them unmodifiable and unerasable. Combined with the signal authenticity verification mechanism of mirror resonance coupling, this further strengthens security protection and effectively resists malicious cracking, parameter tampering, and human sabotage.
[0025] 5. In this invention, the main control terminal and all heterogeneous slave terminals have reserved pin-type and magnetic standardized hardware expansion interfaces, which support hot-swapping. Pure hardware expansion modules such as photosensitive monitoring, temperature warning, and active deterrence can be connected without modifying the original circuit of the main control terminal. After the expansion module detects the trigger condition, it directly links with the priority decision unit to realize alarm, warning or active deterrence actions.
[0026] 6. In this invention, a single master terminal supports multiple heterogeneous slave terminals, which can simultaneously protect various types of personal valuables such as wallets, ID cards, bags, mobile phones, and tablets. The slave terminals can be installed in a flexible manner to meet the personalized security needs of different users. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Example
[0033] Please see Figure 1 - Figure 4 As shown, a portable multi-device minimalist hardware collaborative security system includes a single master terminal and multiple heterogeneous slave terminals.
[0034] Heterogeneous refers to at least two terminals that differ significantly in physical form, power supply method, or installation method.
[0035] The main control terminal has a built-in pure hardware control unit, frequency identification unit, priority decision unit, alarm unit, independent power supply module and anti-tampering unit. The frequency identification unit is a hardware resonant circuit with at least one set of fixed resonant frequencies preset, and the resonant frequencies are fixed in the frequency identification unit through fuses.
[0036] The heterogeneous slave terminals include at least one of the following: passive card for personal use, magnetic terminal for bags, and mobile phone patch terminal. Each heterogeneous slave terminal has a built-in physical monitoring unit and signal interaction unit. The heterogeneous slave terminals and the master terminal establish a primary status monitoring link through contact physical connection or magnetic field coupling to achieve primary status monitoring.
[0037] The frequency identification unit acquires signals from heterogeneous slave terminals through frequency resonant coupling and automatically identifies the type of heterogeneous slave terminals. The priority decision unit is built based on pure logic gate circuits and is used to implement fixed priority alarm decision. When the first-level status monitoring link is disconnected, abruptly changed, removed, cut off or pulled out, the pure hardware control unit controls the alarm unit to trigger the priority alarm corresponding to the heterogeneous slave terminal within a preset time threshold after the occurrence of the abnormal state.
[0038] The connection method includes at least one of magnetic field coupling, magnetic connector, conductive wire, pull rope, steel wire rope, conductive clamp, normally closed switch, and tripping structure; and the frequency identification unit collects signals from heterogeneous slave terminals through mirror resonant coupling to achieve automatic identification and signal authenticity verification. The decision logic of the priority decision unit is linked with the signal authenticity verification result. The mirror resonant coupling means that the resonant frequency of the slave terminal and the identification frequency of the master terminal are mirror-corresponding, or the signal is verified bidirectionally through load modulation.
[0039] In this embodiment, specifically: the priority decision unit is built using a NAND gate chip and a hardware self-locking circuit. The rule for determining the fixed priority alarm is that different resonant frequencies correspond to different alarm priorities. Among them, the priority of the close-fitting anti-pickpocketing alarm corresponding to the low frequency band is higher than the priority of the close-fitting anti-drag alarm corresponding to the mid frequency band; the priority of the close-fitting anti-drag alarm corresponding to the mid frequency band is higher than the priority of the mobile phone anti-forgotten alarm corresponding to the high frequency band; when a high-priority alarm is triggered, the priority decision unit automatically blocks the low-priority alarm signal.
[0040] The fixed priority alarm decision rules are embedded in the NAND gate chip and self-locking circuit through hardware wiring and cannot be modified by software, external configuration signals or parameter adjustments.
[0041] In this embodiment, specifically: the frequency identification unit is composed of an LC resonant circuit, with three preset fixed resonant frequencies: 1kHz, 2kHz, and 3kHz. These frequency parameters are fixed at the factory via fuses. The 1kHz signal corresponds to a passive card attached to the body, representing the highest priority; the 2kHz signal corresponds to a magnetic terminal for bags, representing medium priority; and the 3kHz signal corresponds to a mobile phone patch terminal. Priority decision: the priority decision unit uses a hardware self-locking circuit built with a 74HC00 NAND gate chip. The circuit logic is designed as follows: when the 1kHz signal is triggered, the circuit locks the high-level output to drive the alarm, and at the same time, it forcibly pulls down the input terminals of the 2kHz and 3kHz channels through the feedback loop, preventing them from triggering the alarm. Similarly, when the 2kHz signal is triggered, the 3kHz channel is blocked.
[0042] Those skilled in the art should understand that the above frequencies are merely examples, and any combination of frequencies that can be distinguished by hardware circuitry and satisfy priority decision logic falls within the protection scope of this invention.
[0043] In this embodiment, specifically: the main control terminal also has a built-in wireless communication module. When the primary status monitoring link fails to work properly due to physical disconnection, magnetic field coupling failure, or distance exceeding the preset range, the pure hardware control unit controls the wireless communication module to be automatically activated. The wireless communication module performs secondary anti-forgotten monitoring and triggers secondary alarms based on the wireless signal strength being lower than the preset signal strength threshold or the wireless connection being disconnected. The secondary alarms and the priority alarms triggered by the primary status monitoring link are independent of each other and do not interfere with each other.
[0044] In this embodiment, specifically: Level 1 status monitoring link: In the default working mode, the terminal status is monitored in real time through physical wires or near-field magnetic field coupling, i.e., at a distance of <10cm. Once the connection line is cut or the magnetic attraction is forcibly separated, the frequency resonance signal disappears instantly or changes abruptly, and the system triggers an alarm within 0.1 seconds.
[0045] Wireless communication module: By default, it is in sleep mode when powered off. It will only turn on the power when the primary link fails, for example, when the user takes the main controller out of the magnetic field coupling range but does not trigger the cut-off alarm (it may be forgotten) or when the pure hardware control unit detects that the distance exceeds the limit (>5 meters).
[0046] When the wireless module is activated, it detects the signal strength. If RSSI < -70dBm, it is determined to be a valid forgetting and triggers a secondary alarm with a "beep" sound. If a high-priority alarm is also triggered at the primary link at the same time, such as during a robbery, the secondary alarm of the wireless module will be suppressed by hardware logic to avoid noise interference with the distress call.
[0047] In this embodiment, specifically: the wireless communication module is at least one of Bluetooth BLE module, UWB module, and RF module, and the wireless communication module is only activated when the first-level status monitoring link fails, and is in a dormant state in other states.
[0048] In this embodiment, specifically: the anti-tampering unit includes a metal shielding layer and an anti-tamper trigger normally closed switch. The metal shielding layer covers the inside of the main control terminal's housing, and the anti-tamper trigger normally closed switch is connected in series in the main circuit of the main control terminal. When the housing of the main control terminal is disassembled, the anti-tamper trigger normally closed switch triggers a disassembly signal. The pure hardware control unit controls the alarm unit to trigger a first-level alarm based on the disassembly signal and cuts off the power supply circuit of the wireless communication module.
[0049] In this embodiment, specifically: the master terminal and each heterogeneous slave terminal are equipped with a standardized hardware expansion interface. The standardized hardware expansion interface is a pin-type socket or a magnetic contact. The standardized hardware expansion interface is used to connect external functional expansion modules.
[0050] In this embodiment, specifically: the external functional expansion module is at least one of a photosensitive monitoring module, a temperature sensing early warning module, and an active deterrence module; the pure hardware control unit, based on the working signal transmitted by the external functional expansion module, links and controls the alarm unit to trigger an alarm, or directly activates the external functional expansion module to perform deterrence actions such as flashing, releasing dye, or spraying. The release of dye includes, but is not limited to, the following two methods:
[0051] Ink sac rupture: The internal sealed ink sac is punctured or crushed by a mechanical triggering structure (such as a firing pin or a squeezing component), and the dye is instantly released by the internal pressure.
[0052] Dye spraying: The dye in the storage tank is actively sprayed out through a micro pump, compressed gas or electromagnetic drive device;
[0053] Furthermore, as can be seen from the above embodiments, the specific structure for achieving dye efflux is not limited to this. Any mechanism that uses equivalent substitution to transfer the dye from the inside of the terminal to the outside and attach it to the target is included in the disclosure of this invention.
[0054] In this embodiment, specifically: the activation signal of the active deterrence module is a combination of a rapid disconnection signal and an impact signal collected by the primary state monitoring link.
[0055] In this embodiment, specifically: the inner side of the main control terminal shell is wrapped with a copper metal shielding layer, which not only prevents external electromagnetic interference, but also serves as part of the anti-tamper sensor.
[0056] The main circuit has a micro-switch that is normally closed and connected in series with the housing seam.
[0057] The anti-tamper logic is as follows: Once the outer casing is pried open, the normally closed switch pops open, the circuit is broken, the pure hardware control unit detects the open circuit, immediately drives the buzzer to emit a maximum volume alarm, and physically cuts off the VCC power supply line of the wireless module through the MOSFET. Even if the attacker quickly reassembles the outer casing, the wireless module is already powered off and cannot send a "stop alarm" command or reveal its location. Secondly, the system has reserved a standardized hardware expansion interface, allowing users to connect an external active deterrent module. Trigger conditions: The system not only monitors "disconnection" but also "impact". When the accelerometer (implemented by a hardware comparator) detects a severe impact, accompanied by a rapid disconnection of the connection line, the two form a logical combination that directly triggers the deterrent module to perform a strobe and spray, without the need for complex software judgment.
[0058] In this embodiment, specifically: a physical button is provided on the surface of the main control terminal's housing. The physical button is used to send a global mute command or a forced reset command to the pure hardware control unit; at least one heterogeneous slave terminal supports dual-mode adaptation of passive mode or active mode. In the passive mode, the heterogeneous slave terminal achieves power supply and signal recognition synchronously through mirror magnetic field coupling with the main control terminal, without the need for an additional power supply module.
[0059] In this embodiment, specifically: the independent power supply module built into the main control terminal is a long-lasting power supply module, which can continuously power the device for several months in the preset working mode; when the frequency identification unit is within the preset coupling distance range of the heterogeneous slave terminal, it can achieve automatic resonant coupling, terminal identification and automatic arming within a preset time.
[0060] In this embodiment, specifically: some heterogeneous slave terminals, such as personal cards, support passive mode. They do not have internal batteries, but instead use the alternating magnetic field emitted by the master terminal to draw power and modulate the load changes back to the master terminal. This method allows the slave terminals to theoretically have unlimited lifespan and are extremely thin and easy to hide. The independent power supply module of the master terminal adopts a low-power design. In pure hardware monitoring mode, the standby current is only in the microamp level. With a large-capacity lithium-ion battery, it can work continuously for more than 12 months.
[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
