Background technology
Computer in the computer room of Internet bar and each middle and primary schools, junior college, universities and colleges of undergraduate course computing machine classroom and units such as each R﹠D institution, bank does not adopt anti-theft measure mostly at present, though the computer of part adopts the antitheft mode of various machineries, as:
1, adopt the computer antitheft cabinet: antitheft cabinet generally is equipped with special-purpose snap close, reserves the mechanical lock upper lock position, need unblank just can open cabinet the tamper-proof design of fuselage steel plate;
2, install the rack computer antitheft additional: install cupboard additional to loom, and pin with timber or iron gate;
3, adopt closed-circuit control Internet bar computer antitheft: the some closed circuit camera probes of inner installation are monitored in the Internet bar, are equipped with special monitoring computer at control and monitor console and monitor, and can also realize recording function in monitoring; But the antitheft mode of machinery is because of with low content of technology, unreliable, destructible, can not monitor in real time, and is still hard to guard against, can't satisfy the requirement of computer antitheft.
In addition, also have the mode of the computer employing alarm of minority, as:
1, install the Chassis Intrusion simple alarm additional: adopt magnet induction control, magnet one separately sends chimes of doom immediately, need not to transform cabinet, only needs alarm is attached to the interior survey of cabinet.But this alarm is subject to magnet to be disturbed, and as adhere to a strong magnets at the cabinet iron-clad, this alarm lapses; Adopt little button cell, serviceable life is short, and voltage is low, and the chimes of doom that sends can be very not high, to can't hear chimes of doom in the noisy computerized environment; Can only prevent that entrance of cabinet is stolen, can not prevent that computer is local stolen as the chassis power supply back from other; Can not be antitheft to valuable peripheral hardwares such as LCD;
2, the on-the-spot special alarm of computer: in a single day cabinet is opened, alarm sends the high-decibel alarm sound, the cabinet start detects adopts the special electronic switch, not responded to by magnet, damage resistance is strong, and the while, an alarm can detect the unlatching of cabinet left baffle, front apron and chassis power supply, realized the omnibearing protection of cabinet, but there is shortcoming: battery is short service time, frequently changes the battery trouble; And do not have indication after the dead battery, easily cause and fail to report the police; The cost height, the battery expense is big, and user's difficulty is born.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of computer theft deterent alarm that utilizes dual power supply device power supply mode and energy intelligent conversion is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of computer theft deterent alarm comprises alarm host machine, single-chip microcomputer, pir intrusion detector device, Peripheral Interface, cabinet detector switch interface, wireless launcher and supply unit, and it is characterized in that: supply unit comprises DC voltage-stablized source apparatus and battery; Wherein, described pir intrusion detector device connects Peripheral Interface, and described Peripheral Interface connects single-chip microcomputer, and described single-chip microcomputer connects wireless launcher and cabinet detector switch interface, and described supply unit is to each device device power supply.
And described battery adopts lithium battery.
And described wireless launcher adopts high-quality copper telescopic antenna, and this antenna has 5 joints, and the length of every joint is 10-15 centimetre.
And described alarm host machine connects audible-visual annunciator.
Advantage of the present utility model and good effect are:
1, the utility model adopts DC voltage-stablized source apparatus and the two devices of battery that alarm is powered, and under the situation of civil power outage, battery carries out powered operation immediately; When battery electric quantity was not enough, alarm can send warning message notice computer control personnel according to the pre-set programs of single-chip microcomputer it is changed.Even outage, this alarm still can operate as normal, and be unaffected, prevent the loss that alarm causes because of outage.
2, the utility model is reasonable in design, adopts Wireless transmission mode that computer is carried out intelligent alarm, by the pir intrusion detector device main frame is connected with display, prevents that computer is stolen; Simultaneously, adopt the pattern of dual power supply to avoid that not have the computer that electricity causes stolen because of power supply, and this device function of also having anti-dismounting warning, short-circuit alarming, breaking alarming, damage preventing alarm and preventing from reporting by mistake.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
A kind of computer theft deterent alarm, as shown in Figure 1: a kind of computer theft deterent alarm, comprise alarm host machine 7, single-chip microcomputer 1, pir intrusion detector device 2, Peripheral Interface 3, cabinet detector switch interface 4, wireless launcher 5 and supply unit 6, it is characterized in that: supply unit 6 comprises DC voltage-stablized source apparatus and battery; Wherein, described pir intrusion detector device 2 connects Peripheral Interface 3, and described Peripheral Interface 3 connects single-chip microcomputer 1, and described single-chip microcomputer 1 connects wireless launcher 5 and cabinet detector switch interface 4, and described supply unit 6 is to each device device power supply.Described battery adopts lithium battery; Described wireless launcher 5 adopts high-quality copper telescopic antenna, and this antenna has 5 joints, and the length of every joint is 10 1 15 centimetres; Described alarm host machine 7 connects audible-visual annunciator.
