Description
Technical field
The utility model relates to a kind of computer equipment, more precisely a kind of computer housing with anti-theft alarm function.
Background technology
Computer housing is a kind of very important computer hardware equipment, each computer is all configured with a cabinet, the equipment such as hard disk, CPU of computer is all configured in cabinet, because computer housing is more valuable, so the object of a lot of thief stealing can be become, if computer housing will be caused larger economic loss by thief's stealing, therefore, a kind of computer housing with anti-theft alarm function can be produced.
Summary of the invention
The purpose of this utility model is to provide a kind of computer housing with anti-theft alarm function.
The purpose of this utility model is by realizing with under type:
A kind of computer housing with anti-theft alarm function, comprise machine case body (1), it is characterized in that the bottom of machine case body (1) is provided with pressure transducer (2), in machine case body (1), be provided with power supply (3) and wiring board (5), have switch (4) in the outer setting of machine case body (1).
Described wiring board (5) is provided with amplifying circuit (6), A/D change-over circuit (7), single-chip microcomputer (8), contrast device (9) and hummer (10).
Described power supply (3) is connected to described switch (4) and single-chip microcomputer (8) successively.
Described pressure transducer (2) is connected to described amplifying circuit (6), A/D change-over circuit (7) and single-chip microcomputer (8) successively.
Described single-chip microcomputer (8) is electrically connected with described contrast device (9) and hummer (10) respectively.
The utility model compared with prior art has the following advantages: on computer housing, arrange burglar alarm due to adopting, so just can play good anti-theft effect.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structured flowcharts of the present utility model.
In figure: 1, machine case body, 2, pressure transducer, 3, power supply, 4, switch, 5, wiring board, 6, amplifying circuit, 7, A/D change-over circuit, 8, single-chip microcomputer, 9, contrast device, 10, hummer.
Embodiment
With reference to accompanying drawing 1,2 as follows:
A kind of computer housing with anti-theft alarm function, comprise machine case body 1, pressure transducer 2, power supply 3, switch 4, wiring board 5, amplifying circuit 6, A/D change-over circuit 7, single-chip microcomputer 8, contrast device 9 and hummer 10, it is characterized in that the bottom of machine case body 1 is provided with pressure transducer 2, power supply 3 and wiring board 5 is provided with in machine case body 1, switch 4 is had in the outer setting of machine case body 1, wiring board 5 is provided with amplifying circuit 6, A/D change-over circuit 7, single-chip microcomputer 8, contrast device 9 and hummer 10, power supply 3 is connected to switch 4 and single-chip microcomputer 8 successively, pressure transducer 2 is connected to amplifying circuit 6 successively, A/D change-over circuit 7 and single-chip microcomputer 8, single-chip microcomputer 8 is also electrically connected with contrast device 9 and hummer 10 respectively, open switch 4, when machine case body 1 is positioned on computer desk, the force value that pressure transducer 2 is measured equals to contrast the value arranged in device 9 after amplifying circuit 6 and A/D change-over circuit 7 are changed, hummer 10 can not sound the alarm, when there being people to be moved away from from computer desk by machine case body 1, the force value that pressure transducer 2 is measured will change, single-chip microcomputer 8 can trigger hummer 10, make it sound the alarm, the utility model structure is simple, be easy to manufacture.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
