Description
Technical field
The present invention relates to mobile phone, particularly relate to a kind of mobile phone that can detect and report to the police the concentration of toxic gas such as alcohol or carbon monoxide in the gas.
Background technology
At present, because people drive when intoxicated, the contingency that causes on duty has caused tremendous loss for resident and society.Relevant statistics show, only the traffic accident whole nation of causing because of driving when intoxicated the first half of the year in 2003 has 5666, causes 1944 people's death, and accident death rate is every 0.34 people, per 3 are just caused 1 people's death, are much higher than every 0.15 people's average accident death rate.
Equally, gas poisoning fatal accident has caused tremendous loss also for resident and society.Relevant data shows that in recent years, Beijing's gas poisoning fatal accident frequently takes place, and particularly during the warming of 2002-2003, the gas poisoning fatal accident sharply rises.According to statistics, 63 of gas poisonings take place during this period altogether, dead 99 people, accident plays number rising 57% on year-on-year basis, and death toll rises 90%.
The problems referred to above are owing to lack a kind of can carrying to a great extent, and the checkout gear that can use whenever and wherever possible, make people can't learn due to the own alcohol and the concentration and unsafe condition of toxic gases such as coal gas that reaches at one's side.Described toxic gas comprises flammable toxic gas and incombustibility toxic gas, and wherein flammable toxic gas comprises liquefied gas, natural gas, coal gas, butane, propane, methane, alcohol etc.; The incombustibility toxic gas comprises hydrogen sulfide, ammonia, carbon monoxide, sulfur dioxide, smog etc.Yet the checkout equipment of toxic gases such as present alcohol or carbon monoxide generally all is the special equipment that is not easy to carry, and they can not satisfy the requirement that people use whenever and wherever possible.And extensively popularize at present, can carry, and the mobile phone that can use does not whenever and wherever possible but have this function.Simultaneously, also still not having toxic gas checkout gears such as the portable alcohol of other type or carbon monoxide up to now occurs.
On the other hand, with regard to the gas sensor of toxic gases such as alcohol or carbon monoxide detection usefulness, its kind is more.By used gas sensitive and gas-sensitive property difference, can be divided into semiconductor-type, solid electrolyte formula, electric chemical formula, catalytic combustion type, high score minor etc.At present, gas sensor is to low-power consumption, multi-functional, integrated direction development, and this just makes that gas sensor is embedded into general handheld device (as mobile phone) becomes possibility.
Summary of the invention
The present invention is intended to address the above problem, can carry and provide a kind of, so that understand the concentration situation of user oneself and toxic gases such as alcohol at one's side and coal gas at any time, and in time adopt an effective measure and break away from and avoid danger, reduce the mobile phone with alcohol or toxic gas detection and warning function of carrier's life and property loss.
For achieving the above object, the invention provides a kind of mobile phone with alcohol or toxic gas detection and warning function, it is to be connected with a Detection Circuit that is used for alcohol or toxic gas detection on the main circuit of the inside of mobile phone.
The present invention also can be furnished with an external gas-detecting device that is used for alcohol or toxic gas detection on mobile phone, this gas-detecting device is made of the housing of band plug and the Detection Circuit that is contained in the housing, during use the housing plug is inserted the communication interface of mobile phone.
Detection Circuit is formed by gas sensor, analog to digital converter and gas detecting controller serial connection, and Detection Circuit is connected with the mobile phone central processing unit by the gas detecting controller, which is provided with communication interface.
The gas detecting controller is a single-chip microcomputer, and its input is connected with analog to digital converter, and its output is connected with the mobile phone central processing unit by its communication interface.
Gas sensor comprises alcohol sensor and toxic gas sensor, and they are connected in the input of analog to digital converter.
Detection Circuit is separately set on the circuit board, and circuit board then is contained in the mobile phone by the bottom.Detection Circuit also can be set to one with the inside main circuit of mobile phone.
Alcohol or toxic gas detect the Keyboard Control by mobile phone, and the detection data of quantification are presented on the lcd screen of mobile phone.
The external gas-detecting device can be by the powered battery that places in the housing, or is powered by battery of mobile telephone.
The software control flow process that Detection Circuit of the present invention is carried out alcohol or toxic gas detection is as follows:
A, user send by keypad for cellular phone and detect instruction;
After b, mobile phone central processing unit receive the instruction of the start detection that the user sends, the instruction of start detection is delivered to the gas detecting controller, on lcd screen, shows simultaneously and detect log-on message;
After c, gas detecting controller receive the instruction of the start detection that mobile phone sends, send the startup conversion instruction to analog to digital converter, and cycle detection analog to digital converter EOC whether, if its EOC, just read the data after the conversion, and to its compensate, treatment for correcting, the data after handling are sent to the mobile phone central processing unit;
D, mobile phone central processing unit enter waits for that the gas detecting controller sends testing result information, if the gas detecting controller is finished detection, the mobile phone central processing unit is according to the testing result that receives, whether decision needs to start the warning the tinkle of bells, and the result that will detect is presented on the lcd screen.
Operation principle of the present invention after the keyboard start detection operation by mobile phone, is sent sense command to Detection Circuit, the gas detecting controller start detection process of Detection Circuit by the central processing unit of mobile phone as shown in Figure 4.When gas sensor touch gas to be detected after, can change the concentration information of detected gas into the signal of telecommunication, by signal amplification circuit this signal of telecommunication is amplified to the input range that analog to digital converter needs, this moment, analog to digital converter changed the analog electrical signal of input into corresponding digital information, by single-chip microcomputer this digital information is handled, after the compensation, data after handling are sent to the mobile phone central processing unit by standard communication I2C or UART, this processor is presented at result data on the LCD screen then, reports to the police by the tinkle of bells in case of necessity.
The present invention makes people can understand the concentration situation of oneself and toxic gases such as at one's side alcohol and coal gas at any time, and in time adopts an effective measure and break away from and avoid dangerous, reduces life and property loss.Obviously, the present invention can significantly reduce the accident of poisoning and causing owing to alcohol or toxic gas.
