Abstract
The invention discloses an indoor environment quality monitoring-based data acquisition method. Whether task suspending time of a data acquisition subtask is up is examined; if so, ready state entrance is realized; and when another task with the higher priority is executed completely, CPU control authority is obtained and data acquisition work is started; initialization and setting are carried out on a relevant register in a microprocessor and data acquisition work from a channel 0 to channel 4 is successively completed; the data are transmitted to a data storage subtask and are stored in a NandFlash unit so as to realize further processing by a data processing subtask; and after all work is over, the task is suspended by a delay way. According to the method, the efficiency is high. The digital signal output can be obtained directly and can be read by microprocessor, so that there is no need to carry out setting and initialization of the relevant register of the built-in A/D converter arranged inside the microprocessor; and data acquisition time is saved.
Description
Technical field
The present invention relates to a kind of collecting method based on Indoor Environmental Quality monitoring.
Background technology
At present, the data acquisition of Indoor Environmental Quality monitoring system is all to use sensor to carry out data acquisition, in each sensor assembly typically used, including Temperature Humidity Sensor module, formaldehyde sensor module, ammonia gas sensor module and carbon monoxide transducer module, the inside of these sensors all comprises the A/D converter of a higher precision, data acquisition modes of the prior art is difficult to directly obtain digital signal, the related register needing the A/D converter built-in to microprocessor is configured and initializes so that the efficiency of data acquisition is the lowest.
Summary of the invention
The present invention seeks to provide a kind of collecting method based on Indoor Environmental Quality monitoring for the defect that prior art exists.
The present invention is for achieving the above object, adopt the following technical scheme that a kind of collecting method based on Indoor Environmental Quality monitoring, whether first check for the task suspension time of data acquisition subtask to the time, if being put into ready state to the time, after the tasks carrying of other higher priority, just obtain the control of CPU, and turn-on data collecting work；It is then followed by the related register in microprocessor is initialized and arranged, is sequentially completed the passage 0 data collection task to passage 4；Finally these data being passed to data storage subtask, and store data in NandFlash, in order to data process subtask and are further processed, after all working terminates, this task time delay is hung up.
Beneficial effects of the present invention: the collecting method efficiency of the present invention is high, can directly obtain digital signal output, and by microcomputer reads, the related register of A/D converter that thus need not be built-in to microprocessor is configured and initializes.Save the time of data acquisition.
Accompanying drawing explanation
The data acquisition flow figure of Fig. 1 present invention.
Detailed description of the invention
Shown in Fig. 1, for a kind of collecting method based on Indoor Environmental Quality monitoring, whether first check for the task suspension time of data acquisition subtask to the time, if being put into ready state to the time, after the tasks carrying of other higher priority, just obtain the control of CPU, and turn-on data collecting work；It is then followed by the related register in microprocessor is initialized and arranged, is sequentially completed the passage 0 data collection task to passage 4；Finally these data being passed to data storage subtask, and store data in NandFlash, in order to data process subtask and are further processed, after all working terminates, this task time delay is hung up.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
