Abstract
The utility model discloses a prison escape-proof electronic wrist strap, consisting of a wrist strap part and a circuit part. The wrist strap part comprises a shell body (1), a hand strap (2) and a buckle (3). The shell body consists of an upper shell and a lower shell; the shell body is internally provided with a circuit board (5) and a battery (6); the hand strap is fixed at the two ends of the shell body and is internally provided with a wire (8) with a snake-shaped route; and the buckle is used for fixing the hand strap at the two sides. The utility adopts an active RFID technology (2.4G HZ) to realize the location of prisoners in the prison and help to prison service staffs to realize the intelligent management of the prisoners in the prison. The utility model fills the gap that the national prison system has no identifying location to the prisoners in the prison. The electronic wrist strap has small volume and light weight, is waterproof, avoids demolition, has long service life and is comfortable for wearing. The electronic wrist strap has 14 expansion paths, is compatible with a 802.11b, g wireless protocol, and can be seamlessly connected with a standard Access Point. The electronic wrist strap has adjustable emissive frequency, a built-in motion sensor and a built-in temperature sensor.
Description
Technical field
The utility model belongs to technical field of electronic products, and what relate generally to is the anti-electronics wrist strap of escaping in a kind of prison.
Background technology
REID is a kind of automatic identification technology that rises the nineties in 20th century, is to utilize radiofrequency signal to realize that by space coupling (alternating magnetic field and electromagnetic field) contactless information transmission and the information of passing through to be transmitted reach the technology of identifying purpose.Ultimate principle from the information transmission, REID in low-frequency range based on transformer coupled model (NE BY ENERGY TRANSFER between elementary and secondary and signal transmission), at high band based on the space coupling model of radar detection target (radar emission electromagnetic wave signal run into target then carry target information return radar receiver).The frequency of operation of definition RFID product has the interior different product that meets various criterion of frequency range of low frequency, high frequency and very high frequency(VHF) at present, and the RFID product of different frequency range has different characteristics.(100～500KHz) are mainly used in gate inhibition's control, bio-identification, door lock for vehicle to low-frequency range; High frequency (13.65kHz) is mainly used in gate inhibition's control, smart card, single grade label, library and electronic document supervision; (866～956MHz) are mainly used in luggage processing, Fare Collection System to ultrahigh frequency; Microwave (2.45GHz) is mainly used in item tracing, Fare Collection System.Still there is not at present the report of system applies at the prison.
Summary of the invention
The purpose of this utility model is to propose a kind of prison to prevent escaping the electronics wrist strap, is applicable in the prison personnel under detention is discerned the location, to assist prison political affairs personnel the personnel under detention is managed.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is as follows: it is made of wrist strap part and circuit part, wrist strap partly comprises housing, hand band and buckle, housing is made up of last lower house, is provided with circuit board and battery in housing, and the hand band is fixed on the two ends of housing, the belt body tip designs has the double-side saw teeth groove, be provided with the tinsel of snakelike cabling in the belt body, link to each other with tamper alarm module on the housing interior circuit board, buckle is used for fixing both sides hand band.
The active RFID technology (2.4GHz) that adopts the utility model realizes personnel under detention in the prison is positioned, and assists the intelligent management of prison political affairs personnel realization to the prison personnel under detention.Filled up China's prison system the personnel under detention has not been had the blank that identification is located.Its volume is little, and is in light weight, waterproof, tamper, long service life, comfortable wearing.Have and use the interior location receivers of ISM band 2.4GHz Signals ﹠ Systems to communicate and use the ability that energizer is communicated by letter in the low frequency 125KHz Signals ﹠ Systems simultaneously.Have 14 extended channels, compatible 802.11b, the g wireless protocols, can with standard A ccess Point seamless link.Have adjustable transmission frequency and in-built motion sensor and temperature sensor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a circuit block diagram of the present utility model.
Among the figure: 1, housing, 2, the hand band, 3, the double-side saw teeth groove, 4, buckle, 5, circuit board, 6, battery.7 waterproof washers, 8, tinsel.
Concrete implementation
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1, present embodiment is made of wrist strap part and circuit part.Wrist strap comprises housing 1, and hand band 2 and buckle 4, housing 1 are made up of upper and lower casing, and it is firm not fragile to adopt the ABS engineering plastics to make, and enclosure interior is installed hardware circuit board 5 and battery 6.Consider the requirement of waterproof, the junction of last lower house and screw mounting hole place all are equipped with waterproof washer 7.Lower house is designed to arc according to ergonomics, the applying arm.Housing installs back ultrasound wave seam.Hand band 2 is slotted by the housing both sides and is fixed on the two ends of housing, and it is better that hand band 2 adopts soft rubbers to make pliability, and design has double-side saw teeth groove 3 to can be used for fixedly securing wrist strap on the belt body end.All be equipped with the tinsel 8 with snakelike cabling in the belt body of both sides, as shown in the figure, flexible circuit board 8 links to each other with tamper module on the circuit board 5.The disconnection of belt body and damage all can cause triggering the alarm signal of tamper module.Buckle 4 is used for fixing both sides hand band, is divided into the seat of honour and chassis two parts, and the belt body space is reserved in two parts junction, and seat of honour design has four slightly resilient clamps, and is corresponding with four draw-in grooves on the chassis, combines closely behind the fastening, can't manually separate.Two parts also design for arc, the applying arm.Encapsulating is shut after the buckle closure.
In conjunction with shown in Figure 3, circuit part adopts the T2 circuit module of AeroScout company as Fig. 2, by the high frequency transceiver module, and the low frequency receiver module, control module, the tamper alarm modules, power module, motion and temperature sensor are formed.Control module is for being that eight high-speed microprocessors are responsible for controlling high-frequency model transmitting-receiving locator data, and the low frequency module of control can detect two-way low frequency trigger pip simultaneously.The chip aerial that the high frequency transceiver module is used for the integrated RF transceiver of monolithic of ISM band and is used for this frequency range by a slice is formed, be used for the location receiving equipment (LR) of preventing the system of escaping between communicate by letter, to the locating information of LR transmission wrist strap.Low frequency module mainly is made up of the antenna of a slice low-power LF ASK receiver and one group of square crossing, is connected with single-chip microcomputer PTC2--PTC4 in the control module by the I2C bus; Low frequency module receives the trigger pip of 125KHz in real time, and influences the content of wrist strap to the locating information of location receivers transmission, is used for the state that wrist strap is judged by system.The tamper alarm module mainly is made of the tinsel in 8 single-chip microcomputers of a slice and the belt body, and is connected with control module, detects hand band metal wire built-in state in real time.Power module is converted to each functional module required voltage with the output of the lithium battery of 3.6V 1000mhA.Motion and temperature sensor can be monitored wrist strap motion conditions and environment temperature, can change some attribute of wrist strap such as transmission frequency etc. according to situation of change to embody also in locating information.
