Abstract
The utility model is a biological environment recording instrument, which consists of a sensor, an A/D conversion module, a CPU, a power supply module and an outer housing. The sensor, the A/D conversion module, the CPU and the power supply module are all arranged on a circuit board, the sensor consists of five sensors each of which is connected separately and accordingly with the input port of the A/D conversion module to achieve the simultaneous testing for the temperature, relative humidity, light intensity, noise and air pressure. An external device which is connected with CPU output control port and to connect computer is provided on the outer housing, an operating on-off and power indicating light are arranged on the surface of the outer housing. The utility model having a small volume, simple structure, easy operating, can real-time track record the environmental temperature, relative humidity, light intensity, noise and air pressure; all the parameters can be displayed on a computer screen and be proceed relative parameters analysis through corresponding software. The model is an ideal learning tool for present pupils in primary schools and secondary schools to proceed science and environment supervision and research study.
Description
Technical field
The utility model is a kind of coenocorrelation registering instrument.
Background technology
For school eduaction, because the support of the technology of shortage, the teaching and the experiment in past lose contact with reality, shortage is got in touch with surrounding environment, mainly be that the teacher is being shone the textbook demonstration, the student is being shone teacher's imitation, even is dissimilated as the operation of having only the paper pen, make the student feel uninteresting, lost the consciousness of innovation and the space of thinking development to a certain extent.Especially environmental monitoring and the exploration study experiment of carrying out at students in middle and primary schools, instruments used for education are simple, be simply equipped, can not proceed from the reality and satisfy students in middle and primary schools' the interest and start to test desire of seeking knowledge, do not reach the perfect purpose of theory and practice item combination.
The utility model content
The purpose of this utility model is be to solve the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, be convenient to the coenocorrelation registering instrument learning and grasp.
The utility model is achieved in that a kind of coenocorrelation registering instrument, by sensor, A/D converter, CPU, power module and shell constitute, sensor, A/D converter, CPU, power module is arranged on the circuit board, described sensor is made of 5 sensors, respectively with the corresponding connection of input end of A/D converter, to realize temperature, relative humidity, light intensity, noise, detect in the time of atmospheric pressure, described power module is connected with the power control terminal of CPU and A/D converter respectively, working power is provided for CPU and A/D converter, shell is provided with the Peripheral Interface that is connected with the output control terminal of CPU, to be connected with computer, case surface is provided with run switch key and power supply warning light.
Also can be provided with two general purpose I/O interface that is connected with CPU on the described shell, with external two other sensors.
The model of described CPU can be the P80C552 central processing unit.
The utility model is simple in structure, easy and simple to handle, can carry out real-time track record to temperature, relative humidity, light intensity, noise, the atmospheric pressure of environment, all data can show in computer and carry out the related data analysis by supporting corresponding software, are the ideal tools that present students in middle and primary schools carry out science and environmental monitoring and inquiry study.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail:
With reference to figure 1, the coenocorrelation registering instrument is by sensor, A/D converter 6, CPU7, power module 9 and shell constitute, sensor, A/D converter 6, CPU7, power module 9 is arranged on the circuit board, described sensor is by 5 sensors 1,2,3,4,5 constitute, respectively with the corresponding connection of input end of A/D converter 6, with to temperature, relative humidity, light intensity, noise, atmospheric pressure carries out real-time track record, described power module 9 is connected with the power control terminal of A/D converter 6 with CPU7 respectively, working power is provided for CPU7 and A/D converter 6, power module 8 can adopt the mode of No. 5 batteries of two joints to power.CPU7 can adopt the P80C552 central processing unit, RAM storer with 8K, A/D conversion and various external apparatus interface with 10 as serial communication interface, keyboard scanning circuit, 2 general purpose I/O interfaces etc., can make the serviceability of registering instrument improve greatly.Two general purpose I/O interface that is connected with CPU7 that is provided with on the shell, can be external again two other sensors, as pH value sensor, other temperature sensors, carbon dioxide sensor or the like, expanded the usable range of registering instrument.The Peripheral Interface that is connected with output control terminal CPU7 that be provided with on the shell can be connected with computer 8, so that experimental data is analyzed.Case surface is provided with run switch key and power supply warning light.
When the utility model registering instrument uses, at first connect computing machine, press the run switch button, the warning light flicker, by supporting software, every experimental data that sensor is collected in the automatic detection record instrument of computing machine, and finish the work of treatment of experimental data.The data of gathering can be made various ways such as figure, form, numerical table, the data of gathering can also send among the Excell easily, and can carry out the simple mathematical statistical computation, but also offline operation, to be collected finishing, the student can carry out data with the computer instrument and download, and each experiment sample can contain 256 sample datas.Coenocorrelation registering instrument volume of the present utility model is little, only is 100 * 60 * 20, and is easy to carry, and the student can carry out indoor, outdoor environment measurement like a cork.
