Description
Technical field
The utility model relates to a kind of single chip computer teaching instrument, is specifically related to a kind of Sensor Gas and detects Teaching Module.
Background technology
In the last few years, along with the raising of people's living standard, the recoverable amount of China's automobile rises year by year, and the frequent accidents caused of driving when intoxicated occurs, and for this reason, drunk driving is listed within the scope of criminal law by China.So devise the curricula of sensor alcohol detection in sensor teaching, student is allowed to fully understand the Principle and application of gas sensor, the practical competence of student can not only be improved, and there is the effect of law publicity, allow student have cognition definitely to the illegal row of drunk driving.The biosensor assay case of current most domestic teaching has alcohol detection sensor, but needs and corresponding chamber support the use, and its module integration degree is very high, the switching can not carrying out different sensors uses, Students in Teaching can operational readiness low, be unfavorable for student's hands-on.And alcohol detection Sensor box price is higher, cause instruction cost high.
Summary of the invention
The utility model is high for existing biosensor assay case integrated level, cannot external, switch different sensors and carry out the problem of education experiment, the Sensor Gas devising a kind of pluggable switching detects Teaching Module.
Design proposal of the present utility model is as follows: a kind of Sensor Gas detects Teaching Module, the light-emitting diode display, the button keyboard that comprise power supply, processor and be connected with processor, also include analogue collection module, be connected with processor, for pick-up transducers voltage signal and convert the discernible input signal of processor to, analogue collection module connects direct insertion chip carrier socket by pluggable wiring, and for grafting sensor chip, each pin circuit of chip carrier socket is pluggable.
This Teaching Module is also provided with sound and light alarm module, is connected with processor, is provided with alarm lamp and buzzer siren.Adopt pilot lamp flicker and buzzing two kinds of type of alarms.
This Teaching Module is also provided with debugging interface, is connected with processor, and for being connected with computing machine by processor, carry out on-the-spot teaching detail programming, student can programme at scene on computers, and then programming enters in the processor of Teaching Module, carries out programming test.
Gas sensor, is inserted in chip carrier socket, for measurement gas parameter, and converts voltage signal to.Adopt chip type sensor, as MQ3 alcohol sensor, MQ2 smoke transducer and other gas sensors such as methane, carbon dioxide.When sensor chip output pin is different, the circuit connection of adjustable chip carrier socket, adapts to different sensors chip pin and arranges.
This Teaching Module applying flexible, can realize compile on-line and go, and sensor adopts socket direct insertion, and directly plug can change gas with various sensor into, be conducive to the hands-on to student, a merit is multiplex, has not only saved experimental cost but also arrived teaching purpose.Solve that chamber cost in sensor teaching is high, consume energy high problem, provide the intelligent sensor that a kind of cost is low, usefulness is low to detect Teaching Module.
Accompanying drawing explanation
Fig. 1 is a kind of sensor Alcohol mental disorders Teaching Module theory structure schematic diagram;
Fig. 2 is control panel structural representation;
Wherein, 1 power switch, 2 arrange key, and 3 concentration arrange key, 4 alarm lamps, 5 hummers, 6LED display.
Embodiment
Below in conjunction with specific embodiment and Figure of description, the utility model is described in further detail.Specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
Embodiment: as shown in Figure 1, a kind of sensor Alcohol mental disorders Teaching Module, by power supply, single-chip microcomputer, sound and light alarm module, Keysheet module, light-emitting diode display, analogue collection module and alcohol sensor are formed, wherein analogue collection module, be connected with single-chip microcomputer, be provided with A/D convertor circuit, for gathering the voltage signal of alcohol sensor and converting the discernible input signal of single-chip microcomputer to, analogue collection module connects direct insertion chip carrier socket by pluggable wiring, for grafting alcohol sensor chip, each pin circuit of chip carrier socket is pluggable, regulate the connection of sensor chip output pin as required.Alcohol sensor adopts MQ3 alcohol sensor chip, is directly inserted on chip carrier socket.
Sound and light alarm module, is provided with alarm lamp and buzzer siren.Adopt pilot lamp flicker and buzzing two kinds of type of alarms.
This Teaching Module is also provided with debugging interface, is connected with processor, for being connected with computing machine by processor, carries out on-the-spot teaching detail programming.
Keysheet module is provided with power switch, arranges key, concentration arranges key, and be arranged on a control panel, light-emitting diode display, the pilot lamp of sound and light alarm module and hummer are also arranged on the control panel, and its layout as shown in Figure 2.The operation setting of control panel: switch on power switch 1, light-emitting diode display shows current real time environment alcohol concentration.Press and once arrange key 2, light-emitting diode display most significant digit display "+" or "-" arranges the alcohol concentration upper limit.When environment alcohol concentration higher than arrange upper limit alarm pilot lamp 4 glimmer, hummer 5 sounding alarm; When environment alcohol concentration is lower than arranging in limited time, alarm lamp 4 extinguishes, hummer 5 stop alarm.
This Teaching Module utilizes MQ3 gas sensor to measure alcohol concentration in air, and be converted to voltage signal, convert to after digital signal through A/D change-over circuit and pass to Single Chip Microcomputer (SCM) system, the process of signal is carried out by single-chip microcomputer and respective peripheral circuit thereof, and pass through the alcohol concentration value of light-emitting diode display display measurement, if fruit measured value exceeds setting range value, then sound and light alarm module carries out sound and light alarm.Alcohol concentration value in air ambient can be detected, and by the Keysheet module threshold values different according to different environment sets, sound and light alarm is carried out to point out harm to the threshold values exceeded.
This module application is flexible, can realize compile on-line and go, environmentally requires setting alcohol concentration scope pond.In the module, MQ3 alcohol sensor adopts direct insertion chip carrier socket to connect, so directly plug can change MQ2 smoke transducer and other gas sensors such as methane, carbon dioxide into, a merit is multiplex, has not only saved experimental cost but also arrived teaching purpose.
Be the utility model preferred embodiment in sum, all changes made according to technical solutions of the utility model, all belong to protection domain of the present utility model when the function of producing does not exceed the scope of technical solutions of the utility model.
