Abstract
An electronic nose alarm controller consists of sensor array with temperature control, information collecting and optimizing module, threshold setting comparing module, optoacoustic alarm unit, voltage converting and controlling module and conrolled electric appliance. It can detect several kinds of gas simultaneously. Inside the sensor probe array, there is a temperature controlling heater controlled by informatino collecting and optimizing module which can optimize the working temperature of the gas sensor according to environment temperature and outlet high-quality processed multiple componnet gas signal. The threshold setting comparing module sends out alarm signal after judgment and comparison. The present invention can monitor multiple component gas with high precision and low cost.
Description
Alarm controller of electronic nose belongs to gas-monitoring and mode identification technology, be applicable in many gaseous environments, to gas detect, monitor, warning and gas identification.
Existing gas-monitoring and warning system all are single gas alarm system, general all is to be made of single gas sensor and detection alarm circuit, as: coal gas leakage alarming device commonly used, smog control and warning system are only to realize coal gas or a certain gas detection.Under many circumstances, in the test environment normally multiple gases mix, need warning system that several species of gasses is detected simultaneously and monitors, therefore if use traditional warning system in the same area, to realize detection and monitoring to multiple gases, many complete equipments will be set, so not only increased the detection cost, and because the existence of intrinsic cross-sensitivity between the gas sensor, can make that the resultant error that detects is very big, influenced the precision of measuring, also can cause false alarm sometimes owing to detecting and monitor error.
In order to overcome the shortcoming of the above legacy system, the invention provides a kind of alarm controller of electronic nose that can detect and monitor many components mixed gas simultaneously.
The present invention is by being with temperature controlled sensor array, information acquisition and optimization process module, threshold design comparison module, acoustic-optic alarm, voltage transitions and control module and controlled electrical equipment to form.Gas sensor array probe is made of the gas with various sensor sensitive a plurality of, works as environmental change, according to the measurand difference, can change gas sensor and form new sensor array, requires to extremely up to meeting monitoring.Place the interior well heater of sensor array under information acquisition and optimization process module controls, can realize optimal control to the sensor array response temperature, thereby obtain best measurement temperature, scope is 150 ℃～500 ℃, the sensor signal that obtains has just realized the electric nasus system of a miniaturization in conjunction with software optimization algorithm and threshold design comparison module, when certain measurand in the mixed gas surpasses established standards, can accurately send warning with acoustooptic form, start the electrical equipment that is attached thereto by power source conversion and control module simultaneously, with the rapid concentration that reduces the harmful gas in institute's control scope, to prevent disaster.
The invention has the advantages that, adopt the inner gas sensor array probe that is equipped with well heater, can detect and monitor multiple gases simultaneously, and can be according to the transposing of popping one's head in easily of different environment.Information acquisition and optimization process module are to the measuring-signal of sensor array, adopt unique algorithm, carry out signal front-end processing and optimize merging, and the working temperature of sensor array adjusted, it is operated under the optimum temperature, obtain the signal output of stable ideal, guaranteed system's signal of outputting high quality continuously and stably; The threshold design comparison module can manually be set according to the difference of any gas national standard, and having avoided the alarm work object can only be the situation of single concentration gases.Whole electric nasus system is optimized, is reported to the police from collection, the processing of signal, traditional as compared with the past pure gas alarm, improved the interference problem that cross sensitivity brings effectively, detection and monitoring accuracy have been improved greatly to multicomponent gas, and greatly reduce the cost of measurement, help in environmental monitoring is from now on used, further promoting.
Accompanying drawing is an embodiment of the invention synoptic diagram,
Fig. 1. be system works synoptic diagram of the present invention;
Now in conjunction with the accompanying drawings the present invention is further described:
The present invention is by being with temperature controlled sensor array 1, information acquisition and optimization process module 2, threshold design comparison module 3, acoustic-optic alarm 4, voltage transitions and control module 5 and controlled electrical equipment to form.
This alarm is placed the multicomponent gas environment, energized starts after by the step-down ballast and has temperaturecontrol sensor array 1 and start working, at this moment information acquisition and optimization process module module 2 are according to the situation of environment, carry out temperature optimization control to having temperaturecontrol sensor array 1 internal heater, and select its optimum working temperature, to guarantee the stable of response signal.Simultaneously, the signal of information acquisition and 2 pairs of sensor arraies of optimization process module is gathered, merges, is amplified, obtain desirable input with the threshold ratio that guarantees the back than threshold design comparison module 3, when the harmful gas input value of measuring surpasses the standard value that sets according to national environmental standard, acoustic-optic alarm 4 sends signal, start controlled electrical equipment by voltage transitions and control module 5 simultaneously, it is minimum to make that harmful gas concentration drops to, and gas concentration is closed controlled electrical equipment after recovering normally automatically in controlled area charactert.
