Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The main realization idea of the invention is: using the Bluetooth bracelet to bind with the prisoner outside the prison, the Bluetooth bracelet establishes a connection with the external staff through the Bluetooth, and the client of the supervisor is installed in the mobile of the prisoner. In the terminal, the client of the supervisor connects to the server of the management terminal through the Internet; when the Bluetooth bracelet is disconnected from the client of the supervisor, the client of the supervisor sends a message of disappearing alarm to the server of the management terminal; The external client is disconnected from the server of the management terminal The server generates a fault alarm and saves it. The Bluetooth bracelet periodically sends the Bluetooth address to the external staff. The external client sends the Bluetooth address and the GPS location information of the mobile terminal to the server of the management terminal. The server sets the electronic fence and serves as a prisoner. When the scope of activities exceeds the preset activity range, the “cross-border warning” message is sent to the client and server of the prisoner; in addition, if the Bluetooth bracelet is broken, the demolition alarm message will be sent to the external staff. And the server, the server will send the saved information to the supervisory client in real time, effectively realizing the supervision of the prisoner.

The following is a detailed description of this low-power anti-demolition Bluetooth bracelet, as shown in Figure 1:

The invention provides a low-power anti-demolition Bluetooth wristband, comprising a ring body, wherein the ring body has a built-in anti-demolition circuit, and the anti-demolition circuit is as shown in FIG. 1 and includes a Bluetooth chip. 1. Power supply 2, resistor R, capacitor C and conductive loop 3. The conductive circuit 3 is a closed circuit, which is embedded in the ring body and distributed along the circumferential direction of the ring body, so that if the wristband works normally, the conductive circuit 3 is turned on; if the wristband is broken, Then the conductive loop is broken. One end of the conductive circuit 3 is connected to one end of the power source 2 through a resistor R, and the other end is connected to an interrupt interface of the Bluetooth chip 1 , that is, an Int interface; the capacitor is connected between the Int interface and the ground; The other end is connected to the Bluetooth chip 1.

The anti-demolition circuit further includes a crystal oscillator circuit 4, specifically, a 32 MHz crystal oscillator circuit and a 32.678 KHz crystal oscillator circuit connected to the Bluetooth chip 1; the 32 MHz crystal oscillator circuit is used to provide a clock source for the internal clock and In the RF transceiver; the 32.678KHZ crystal oscillator circuit is used Sleep timer and precise wake-up time.

The anti-demolition circuit further includes an LED alarm circuit module 5 connected to the Bluetooth chip 1; the LED alarm circuit module 5 is configured to illuminate an LED when the Bluetooth disconnection or the conductive loop is disconnected. Because Bluetooth loses connection or the conductive circuit is disconnected, it is abnormal and the time is short. Therefore, the LED light is not bright during normal operation, which saves energy.

The tamper-evident circuit further includes an antenna module 6, the antenna module 6 including a radio frequency antenna circuit matching a 2.4 GHz transmission frequency band and a filter network circuit.

Further, the function of accessing a capacitor between the Int interface and the ground is as follows:

The function of the capacitor is “AC-blocking DC”. Therefore, when static, the Int interface is high level, no current flows through the capacitor, which saves energy. At the same time, the capacitor also functions as a storage filter. On the one hand, the bracelet can be filtered out. The high frequency interference introduced by the loop, on the other hand, when the bracelet is broken (the conductive loop is disconnected), the capacitor is discharged through the Int interface and returns to a low level. The resistor R in the circuit is a pull-up resistor, which is generally 20k ohms; and the capacitor can be selected to be less than 1nf for the following reasons.

When the bracelet loop is broken and disconnected, the potential of the Int port satisfies the discharge formula of the capacitor:

τ=R _i C (2)

Where V _cc is the supply voltage (high level), t is the time, τ is the time constant, C is the capacitance, and R _i is the resistance of the discharge loop (the internal resistance of the Int interface).

The Int interface of the Bluetooth chip CC2541, when the falling edge trigger input is set, the internal resistance R _{i is} about 10M ohms. Therefore, when the capacitance C=1nf is selected, τ=100ms can be calculated according to the formula (2). The discharge of the Int interface level (capacitor C) is shown in Figure 2.

It can be seen that when the power supply voltage is V _cc =3V and the capacitance C is selected to be less than 1nf, then after t>2τ=200ms, the Int interface level will be below 0.42V, which is low level.

Set the corresponding Int interface to trigger on the falling edge. When the bracelet is broken, the Int interface returns from low level to low level within 200ms. The falling edge will trigger the interrupt service program of the Bluetooth chip CC2541. The main function is to send a “demolition alarm” to the Bluetooth bracelet. The connected terminal saves the demolition alarm information to the flash memory of the Bluetooth chip CC2541.

The Bluetooth chip 1 further includes an 8 KB RAM random storage and a 2 KB Flash memory; the Flash memory is used to store the teardown alarm information. The flash memory of the Bluetooth chip has the function of not losing power data, so the alarm information in the Flash cannot be cleared by the prisoner, and must be cleared by the administrator using special equipment or programs. This has the potential to prevent the prisoner from breaking the bracelet and then deleting the alarm information in the bracelet and cheating.

The invention provides a low-power anti-demolition Bluetooth wristband, which adopts a low-power Bluetooth 4.0 chip, wherein the demolition circuit fully considers a low-power design, introduces a grounding capacitor, and has no DC power consumption during normal operation; The alarm LED lamp has no power consumption during normal operation, so that the power consumption of the wristband is extremely low. The wristband provided by the present invention can work for at least half a year with a button battery; the conductive loop is provided in the Bluetooth bracelet, once artificial Demolition, the Bluetooth bracelet can immediately send a “demolition alarm” to the terminal connected to the Bluetooth bracelet, and save the demolition alarm information in the flash memory of the bracelet, which cannot be eliminated by itself.

The following describes the binding and management methods of prisoners based on this Bluetooth bracelet:

First, the method for binding the wristband of the supervisor is introduced. As shown in FIG. 2, the method is based on the Bluetooth bracelet, and specifically includes:

In step A1, the Bluetooth bracelet periodically sends a Bluetooth address to the external client;

In step A2, when detecting that the conductive loop built in the Bluetooth wristband is disconnected, the Bluetooth wristband sends a teardown alarm message to the external police client, and saves the teardown alarm information in the flash memory of the Bluetooth wristband.

Specifically, the mobile terminal of the wristband and the prisoner outside the prison sends a Bluetooth address (MAC address) to the mobile terminal of the prisoner outside the prison through a Bluetooth connection, and sends a “demolition alarm” message when the conductive loop is disconnected. In other words, the Bluetooth bracelet is bound to the prisoner outside the prison, and the external personnel are identified and monitored through the Bluetooth address and the “demolition alarm” information.

Specifically, the mobile terminal introduced in the embodiment of the present invention is a smart phone.

The following describes the method for binding the supervisor client. As shown in Figure 3, the method is based on the interaction between the client and the Bluetooth bracelet and the server, including:

Step B1: The external client receives the Bluetooth address periodically sent by the Bluetooth bracelet, and sends the Bluetooth address to the server.

Specifically, the supervisor client is installed in a smart phone of a prisoner outside the prison, and the smart phone has a Bluetooth communication function, so that the Bluetooth wristband information can be received and read by a general-purpose smart phone. .

In step B2, the external client receives the teardown alarm information sent by the Bluetooth bracelet, and proceeds to the management terminal. The server at the end sends the teardown alarm information;

Step B3: When the distance between the mobile terminal and the Bluetooth bracelet is greater than the preset distance and the Bluetooth connection is interrupted, the external client sends a disappearing alarm message to the server;

Specifically, in order to prevent the supervising personnel from placing the smart phone somewhere and leaving the smart phone far away, the embodiment of the present invention designs the transmission power consumption of the Bluetooth wristband: when the smart phone leaves the distance of the wristband by 10 m. The smart phone sends a "disappearance alert" message to the server, and the server provides the information to the supervisor client to notify the manager to take action. This step is actually to bind the smartphones of the prisoners outside the prison to the prisoners.

In step B4, the supervisor client periodically sends the GPS location information of the mobile terminal positioning to the server.

Specifically, the smart phones all have a GPS positioning function. When the smart phone of the prisoner and the prisoner of the prisoner are bound, the location of the smart phone is roughly equivalent to the position of the prisoner, and the smart phone can be used. Supervising the prisoner to monitor the location.

The following describes the supervisor management method. As shown in FIG. 4, the method is based on the interaction between the server and the supervisor client and the supervisor client, and specifically includes:

In step C1, the server receives and saves the Bluetooth address sent by the supervisor client in real time;

In step C2, the server receives and saves the demolition alarm information sent by the supervisor client;

Specifically, the “demolition alarm” is the most serious alarm information, and it is also the guarantee that the system can operate reliably. It is generally malicious and needs to be eliminated! Information is also in the flash memory of the Bluetooth chip Save, you can not recover on your own, you need to supervise the prisoner to the designated location to pay special personnel to recover, this can prevent the prisoner outside the prisoner to remove the Bluetooth bracelet and delete the possibility of demolition alarm information.

Step C3: The server receives and saves the disappearance alarm information sent by the supervisor client, and records the time of disappearing the alarm;

Specifically, when a “disappearance alert” occurs, the administrator may take measures: if the Bluetooth connection can be restored within 5 minutes, the prisoner is considered to be in a normal active state; if the connection is interrupted for more than 5 minutes, depending on the length of time The supervisor may request the prisoner to submit a written report or otherwise communicate with the supervisor.

Step C4: The server receives and saves the GPS location information sent by the supervisor client, and sends the cross-border alarm information to the supervisor client when the preset activity area is exceeded;

Specifically, the server of the management terminal is provided with an electronic map, and according to the GPS information of the smart phone of the prisoner, the position of the supervisor can be located, and the electronic fence is set, and when the supervisor passes the electronic fence, the terminal is managed. The server will automatically send a “cross-border warning” to the client of the supervising personnel, and notify the prisoner to return in time.

Sending a submission to the supervisor client when the time of the fault alarm exceeds a preset time Instructions for written reporting.

If the mobile phone of the prisoner is dead, the mobile phone is restarted, the network is switched, the signal is not good, etc., the mobile phone is disconnected from the server of the management terminal, and the server managing the terminal will form a "fault alarm" alarm message. . A treatment similar to “disappearing alarm” can be adopted. If the connection can be restored within 5 minutes, the mobile phone is in a normal active state; if the connection is interrupted for more than 5 minutes, according to the length of time, the supervisor can request the prisoner Submit a written report or otherwise communicate with the regulated person.

Specifically, the information stored by the server for various types of prisoners includes: identity information, Bluetooth address, various types of alarm information, GPS location information, etc.; the server provides the information to the supervisory client for query and display, facilitating the manager in time. Supervision of prisoners outside the prison.

The following describes the supervisor management system, as shown in Figure 5, including:
