Description

A kind of automatic calling for help method

Technical field

The present invention relates to electronic technology field, refer to especially a kind of automatic calling for help method.

Background technology

The development of automobile has not only produced great function to social economy, and the mankind's life has also been brought to important impact.Automobile has become the main traffic instrument of people's trip, and its convenience is that aircraft, steamer and train are incomparable.

China is as newly emerging economy, become global first automobile consumption state, and the vehicle guaranteeding organic quantity of China has been broken through hundred million at present.Car is many, and road has been blocked up, and traffic hazard is also more and more.

In rural area or night, the traffic hazard death that has a nearly half is succoured and is caused timely owing to can not get, and misses best warning opportunity, or when salvor arrives in, injures and deaths situation is underestimated, and life preserver carries incomplete, and rescue timely and effectively cannot be provided.

How warning message being provided timely and effectively, making rescue personnel have comprehensive understanding to injures and deaths situation, is current problem demanding prompt solution.

Summary of the invention

Unresolved the problems referred to above, the present invention proposes a kind of automatic calling for help method.

Technical scheme of the present invention is achieved in that

A kind of automatic calling for help method, comprises the following steps:

By being arranged on the subepidermal networks of pressure sensors of vehicle, impingement position and dynamics are detected;

By A/D converter, the shock dynamics value signal of analog form is converted to digital form;

By seat sensor, detect the personnel positions distribution situation of seat top;

By sex, height, body weight, blood group, the emergency call connection information of memory stores human pilot;

By GPS locating module output vehicle precise position information;

By single-chip microcomputer, shock dynamics value signal and numbering are gathered, report is clashed in output, and packs with personnel positions distributed intelligence, human pilot information and vehicle position information;

By wireless communication module, package information is sent to Surveillance center by wireless network.

Alternatively, the each pressure transducer in described networks of pressure sensors has fixed number, numbers corresponding impingement position.

The invention has the beneficial effects as follows: by networks of pressure sensors, detect impact events, and will clash into report and personnel positions distributed intelligence, human pilot information package, by wireless network, send to Surveillance center, Surveillance center makes injures and deaths prediction according to clashing into report, carries timely and effectively corresponding tool, medical equipment and lifesaving blood to rescue site.

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the process flow diagram of a kind of automatic calling for help method of the present invention.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

In rural area or night, the traffic hazard death that has a nearly half is succoured and is caused timely owing to can not get, and misses best warning opportunity, or when salvor arrives in, injures and deaths situation is underestimated, and life preserver carries incomplete, and rescue timely and effectively cannot be provided.

The present invention detects impact events by networks of pressure sensors, and will clash into report and personnel positions distributed intelligence, human pilot information package, by wireless network, send to Surveillance center, Surveillance center makes injures and deaths prediction according to clashing into report, carries timely and effectively corresponding tool, medical equipment and lifesaving blood to rescue site.

As shown in Figure 1, a kind of automatic calling for help method of the present invention, comprises the following steps:

By being arranged on the subepidermal networks of pressure sensors of vehicle, impingement position and dynamics are detected;

By A/D converter, the shock dynamics value signal of analog form is converted to digital form;

By seat sensor, detect the personnel positions distribution situation of seat top;

By sex, height, body weight, blood group, the emergency call connection information of memory stores human pilot;

By GPS locating module output vehicle precise position information;

By single-chip microcomputer, shock dynamics value signal and numbering are gathered, report is clashed in output, and packs with personnel positions distributed intelligence, human pilot information and vehicle position information;

By wireless communication module, package information is sent to Surveillance center by wireless network.

In said method, the each pressure transducer in described networks of pressure sensors has fixed number, numbers corresponding impingement position.

Preferably, described single-chip microcomputer is dsp processor.

Above-mentioned dsp processor can be TMS320F2812DSP, is 32 fixed DSPs, and the AD data acquisition that it has EVA, EVB task manager and supporting 12 16 passages, has abundant Peripheral Interface, as CAN, SCI etc.The ADC module of TMS320F2812 is 12 bit resolutions, has the analog to digital converter of pipeline organization, the built-in dual-sampling hold circuit of TMS320F2812, and while keeping data acquisition, window has independently pre-calibration to control.And permission system is to same Channel-shifted repeatedly, allow user to carry out over-sampling algorithm, this more traditional single transformation result has increased more solution, is conducive to improve the precision of sampling.There are multiple trigger sources can start ADC conversion.Switching time fast, ADC clock can be configured to 25MHz, and the highest sampling bandwidth is 12.5MSPS.While building data acquisition system (DAS) with TMS320F2812, needn't external ADC, avoided complicated hardware design.

The present invention detects impact events by networks of pressure sensors, and will clash into report and personnel positions distributed intelligence, human pilot information package, by wireless network, send to Surveillance center, Surveillance center makes injures and deaths prediction according to clashing into report, carries timely and effectively corresponding tool, medical equipment and lifesaving blood to rescue site.

The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
