Description

A kind of device of detecting a lie

Technical field

This utility model relates to a kind of device of detecting a lie.

Background technology

At present a lie detector of specialty need have more the position at measured's chest, brain, arm etc. multiple sensors is set, complex structure, and volume is bigger, operates also more complicated, and for the ordinary people, it is very inconvenient using professional a lie detector.

The utility model content

The purpose of this utility model is, a kind of device of detecting a lie is provided, and it can utilize mobile phone that the measured is detected a lie, simple in structure, advantages of small volume, simple to operate, easy to use.

The technical scheme of this utility model: a kind of device of detecting a lie, comprise mobile phone, also comprise the single-chip microcomputer that is arranged on the mobile phone, ultrasonic transmitter-receiver that is connected with single-chip microcomputer and alarm module.

In aforesaid a kind of device of detecting a lie, said ultrasonic transmitter-receiver is arranged on the mobile phone, through being located at the exploration hole transmitting-receiving ultrasonic signal on the mobile phone, or is connected with USB mouth on the mobile phone through data wire.

In aforesaid a kind of device of detecting a lie, also be provided with signal amplification circuit, A/D convertor circuit between single-chip microcomputer and the ultrasonic transmitter-receiver.

In aforesaid a kind of device of detecting a lie; Also comprise the memory element that is connected with single-chip microcomputer; Be used to store the normal range value that palmic rate, respiratory frequency, blood pressure and body temperature change, also store the algorithm that ultrasonic signal is converted into palmic rate, respiratory frequency, blood pressure and body temperature delta data.

In aforesaid a kind of device of detecting a lie, said alarm module is a speaker.

Compared with prior art; This utility model utilizes ultrasonic technology to obtain measured's palmic rate, respiratory frequency, blood pressure and body temperature change information; The ultrasonic transmitter-receiver of special use is arranged on mobile phone inside; Perhaps be connected with the USB mouth of mobile phone and carry out transfer of data, make simple in structure, advantages of small volume, easy to carry through data wire; Single-chip microcomputer is set in mobile phone, and single-chip microcomputer storage ultrasonic signal transfer algorithm changes normal range value with preset palmic rate, respiratory frequency, blood pressure and body temperature, judges whether to exceed normal range value; If exceed normal range value; The speaker of mobile phone can be reported to the police, and shows that the measured lies, and the operator only needs ultrasonic transmitter-receiver is pressed close to measured's chest; Whether this utility model just can be tested the measured automatically and lie, simple to operate, easy to use; Because on mobile phone, increased the function of detecting a lie, also increased the interest of cell phone entertainment, improved user's experience.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment this utility model is further described.

The embodiment 1 of this utility model: a kind of device of detecting a lie, its structural representation is as shown in Figure 1, comprises mobile phone, also comprises the single-chip microcomputer 1 that is arranged on the mobile phone, the ultrasonic transmitter-receiver 2 and the alarm module 3 that are connected with single-chip microcomputer 1.Said alarm module 3 is a speaker.Said ultrasonic transmitter-receiver 2 is arranged on the mobile phone, and through being located at the exploration hole transmitting-receiving ultrasonic signal on the mobile phone, ultrasonic transmitter-receiver 2 is the ultrasonic transmission/reception chip, can adopt CX20106A.Also be provided with signal amplification circuit 5, A/D convertor circuit 6 between single-chip microcomputer 1 and the ultrasonic transmitter-receiver 2.Also comprise the memory element 7 that is connected with single-chip microcomputer 1; Be used to store the normal range value that palmic rate, respiratory frequency, blood pressure and body temperature change, also store the algorithm that ultrasonic signal is converted into palmic rate, respiratory frequency, blood pressure and body temperature delta data.

The embodiment 2 of this utility model: a kind of device of detecting a lie, its structural representation is as shown in Figure 2, comprises mobile phone, also comprises the single-chip microcomputer 1 that is arranged on the mobile phone, the ultrasonic transmitter-receiver 2 and the alarm module 3 that are connected with single-chip microcomputer 1.Said alarm module 3 is a speaker.Said ultrasonic transmitter-receiver 2 is connected with USB mouth 4 on the mobile phone through data wire, and the ultrasonic signal of reflected back can send on the mobile phone through data wire.Also be provided with signal amplification circuit 5, A/D convertor circuit 6 between single-chip microcomputer 1 and the ultrasonic transmitter-receiver 2.Also comprise the memory element 7 that is connected with single-chip microcomputer 1; Be used to store the normal range value that palmic rate, respiratory frequency, blood pressure and body temperature change, also store the algorithm that ultrasonic signal is converted into palmic rate, respiratory frequency, blood pressure and body temperature delta data.

The operation principle of this utility model: the measured answers a question, and ultrasonic transmitter-receiver 2 is pressed close to measured's chest, and ultrasonic transmitter-receiver 2 begins to send ultrasonic signal to the measured, and receives the ultrasonic signal that reflects.Signal amplification circuit 5 on the mobile phone, A/D convertor circuit 6 carry out signal amplification, AD conversion process to the ultrasonic signal that receives respectively; Transfer algorithm in mobile phone single-chip microcomputer 1 reading cells 7 is converted to palmic rate, respiratory frequency, blood pressure and body temperature changing value with ultrasonic signal.The normal range value that preset palmic rate, respiratory frequency, blood pressure and the body temperature of storage changes in single-chip microcomputer 1 reading cells 7; Judge that palmic rate, respiratory frequency, blood pressure and body temperature changing value are whether in the normal range value that reads; If not in normal range value; Just explain that the measured tells a lie, alarm module 3 can be play preset music and report to the police; If in normal range value, not lie of measured just is described.The flow chart of its operation principle is as shown in Figure 3.
