Description
Technical field
This utility model relates to a kind of early warning system, specifically a kind of industrial automation intelligent monitoring early warning system.
Background technology
Industrial automation is exactly that the various parameters in commercial production are for controlling purpose, realize various process control, in whole commercial production, reduce the operation of manpower as far as possible, and the energy beyond animal can be made full use of with various information to carry out production work, namely it is called that industrial automation produces, and makes the process that industry can carry out production automatically be called industrial automation.
In industrial processes, the measurement problem of various flow medias and the accurate of flow measure oneself becomes an important content in the field such as current industrial TT&C system, energy measurement management.Also all it be unable to do without flow measurement problem in industries such as petrochemical industry, food medicine, processing and manufacturings simultaneously, then traffic monitoring just pours down in the common pass of subjects and rapidly grows up, and flow techniques also absorbs and applies diversified scientific law and process means.
In traffic monitoring, the signal kinds of input is relatively more, and a part is flow signal, and another part is then the physical quantity signal closely bound up with flow, for instance temperature, pressure etc., and these signals directly affect the measurement of the precision of traffic monitoring, particularly gas flow；Egg is in existing traffic monitoring, and the process of the signal such as temperature, pressure is very coarse, is typically all after directly adopting sensor acquisition and sends into processor, and accuracy of detection is low, also result in the less stable of system simultaneously.
Utility model content
The purpose of this utility model is in that to provide a kind of industrial automation intelligent monitoring early warning system, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of industrial automation intelligent monitoring early warning system, including controller, gain control module, alarm module, LED display module, flow transducer, analog switch and front end processing block, described controller connects LED display module respectively, key-press module, alarm module, wireless sending module, interface module, clock circuit, A/D convertor circuit, gain control module and traffic frequency signal deteching circuit, gain control module is also connected with amplifier, amplifier is also respectively connected with A/D convertor circuit and analog switch, analog switch is also connected with front end processing block, front end processing block is also respectively connected with flow transducer, temperature sensor and pressure transducer.
As further program of the utility model: described controller adopts P89C51RD2 single-chip microcomputer.
As this utility model further scheme: described temperature sensor adopts platinum resistance thermometer sensor, Pt100, and adopts trilinear method to measure resistance value.
Compared with prior art, the beneficial effects of the utility model are: this utility model industrial automation intelligent monitoring early warning system, controller is sent after being optimized process to the temperature in traffic monitoring process, pressure monitoring, make system accuracy high, stability is high, system structure is simple, and cost is low, and volume is little.
Accompanying drawing explanation
Fig. 1 is the schematic block circuit diagram of industrial automation intelligent monitoring early warning system.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of industrial automation intelligent monitoring early warning system, including controller, gain control module, alarm module, LED display module, flow transducer, analog switch and front end processing block, described controller connects LED display module respectively, key-press module, alarm module, wireless sending module, interface module, clock circuit, A/D convertor circuit, gain control module and traffic frequency signal deteching circuit, gain control module is also connected with amplifier, amplifier is also respectively connected with A/D convertor circuit and analog switch, analog switch is also connected with front end processing block, front end processing block is also respectively connected with flow transducer, temperature sensor and pressure transducer；Described controller adopts P89C51RD2 single-chip microcomputer；Described temperature sensor adopts platinum resistance thermometer sensor, Pt100, and adopts trilinear method to measure resistance value.
Operation principle of the present utility model is: refer to Fig. 1, in traffic monitoring, the signal kinds of input is relatively more, a part is flow signal, another part is then the physical quantity signal closely bound up with flow, such as temperature, pressure etc., these signals directly affect the measurement of the precision of traffic monitoring, particularly gas flow.
Temperature sensor adopts platinum resistance thermometer sensor, Pt100, in order to measure resistance value accurately, eliminates the impact of lead resistance, and we adopt trilinear method to measure resistance value.
When measuring flow, the signal that various sensors are sent here will carry out anti-interference process, otherwise will be buried by noise signal.Such as when measuring the millivolt input signal after pressure transducer conversion, if it is untreated, the signal of so only small several millivolts will be buried, because A/D converter is also restricted to the signal amplitude of input, additionally the current signal of differential pressure pick-up transmission can not directly be measured, just can measure after being converted into voltage signal, all these are desirable that and input signal are carried out suitable process, therefore we introduce small signal process circuit as front end processing block, the amplification to various signals is also had to require also different, we have employed gain control module to control gain.
Due to the restriction of volume and consider cost, therefore in the detection process of multiple sensor signal, multiple passages share an amplifier, the amplified device of multiple signals delivers to A/D change-over circuit after processing, owing to each input quantity is sent to the signal level difference of amplifier, the gain of amplifier also should difference.
When the various signals that controller receives are beyond setting value, shown by LED display module and pass through alarm module output alarm signal, by wireless sending module, remote terminal being sent alarm signal simultaneously；Key-press module is for the various parameter values of initialization system；Interface module adopts RS232, it is possible to connect the equipment such as printer and system is extended.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that.
