Description
Technical field
The present invention relates to data collecting field, particularly a kind of exclusive data acquisition system.
Background technology
Auto-monitor of surrounding air quality has become the major technique means of China's urban environment air quality monitoring.The data acquisition of ambient air quality monitoring system (AQMS, Air quality Monitoring System) normally realizes by custom-designed data acquisition hardware device.As shown in Figure 1, existing ambient air quality monitoring system, whole hardware of data acquisition is by industrial computer (computing machine) and the expansion card of communicating by letter (being generally the PCI serial port expanding module), and the signals collecting panel is formed.In order to realize that the pollutant analysis instrument in the AQMS measuring system is calibrated, the distribution control circuit of pair calibrating device can also be arranged and to the power control circuit of calibration solenoid valve.
Existing gas pollutant analyser concentration data uses RS-232 (multidrop) mode directly to be sent to industrial computer, and pellet, meteorologic parameter, station voltage etc. are then gathered by TP9400 (black box).The inner switching value IO channel that also has some of black box can realize the control to the gas calibration device.
TP9400 is a data collector as a signal collecting device that designs for environment friendly system specially, and it has following principal feature:
± 12V or+5V power supply;
2.16 the road is single-ended or difference input, 16 precision (± 3Mv), range ± 10V;
3.8 the input of way word, the output of 8 way words;
4.13 road frequency input;
5.RS-232 communication interface (can power) by Serial Port Line;
The AQMS system also needs wind speed when measuring various gaseous contaminants and inspirable particle concentration, wind direction, and atmospheric pressure, humiture, meteorologic parameters such as station voltage are monitored, for meteorological research and assessment provide reliable foundation.But wind speed, wind direction, atmospheric pressure, temperature, humidity sensor, station voltage, electric current, signal form that sensors such as station temperature provide and range may be inequality, for amplitude and the precision that guarantees signal, before meteorologic parameter is gathered, need to use a meteorologic parameter display instrument power supply to be provided for each meteorological sensor, and the signal of meteorological sensor output adjusted, signal form after the processing, unification is 0～5V voltage, the analog channel that re-uses TP9400 is gathered.All digital data acquisitions and analog acquisition function are integrated in one the hardware unit, resource relative fixed, inconvenient flexible expansion analog channel or digital channel; Integrated design makes reliability reduce, in case equipment failure, possible all passages are cisco unity malfunction all.
By the characteristics of TP9400 " 16 tunnel single-ended or difference inputs, 16 precision (± 3Mv), range ± 10V ", according to the Error Calculation and the evaluation method of ADC converter, the error preresearch estimates of AD conversion is not less than 3Mv.As can be known when carrying out the analog channel collection, because the function ratio of acquisition module is more single, can only be with the voltage signal (range can not be set) in 16 the acquisition mode collection fixed range, therefore precision is fixed, dumb, can not satisfy the different requirements under the multiple condition, signal also may be subjected to the influence of communication distance.Existing TP9400 uses digital output channel DO to come the gas calibration device is controlled, and digital quantity and analog quantity functional module all integrate is inconvenient to expand.
Aspect data read, monitoring software must have the driving of 9400TP on the supervisory control comuter, can only read each simulation and switching value data according to certain protocol.Therefore, concentrating and fixing of function makes the reliability of system and extensibility reduce.The singularity of equipment, specificity, like product manufacturer rareness has caused the specificity of agreement.
