Abstract
This utility model discloses a sensor signal processing circuit which comprises of a sensor and a monolithic processor that linked with the sensor,there still set a signal processing modular in the monolithic processor. Sensor may be gas type, or the other type. The sensor signal processing circuit that this utility model provides has elimated the comparator circuit portion to which sensor signal output should goes to in current technology,directly lead sensor signal to the monolithic processor, directly analysiss and processes siganal via sensor signal processing modular setup by monolithic processor, processed signal after being processed by corresponding modular in monolithic processor display or activate actuator. Said circuit has improved the accuracy of sensor circuit greatly, decreased the production costs of circuit.
Description
Technical field
The utility model relates to a kind of electronic communication field, is specifically related to a kind of sensor signal processing circuit.
Background technology
Sensor is a kind of commonplacely measurement, a detecting instrument in the commercial production field, is usually used in the content of detected gas, pressure of fluid or the like.Detected signal carries out next step action being transported to controller unit after treatment.
The existing sensors signal processing circuit after sensor 1 detects respective substance, export the end input of device 2 as a comparison of corresponding signal, and the input of the other end of comparer is by adjustable resistance RW and resistance R dividing potential drop gained as shown in Figure 1.Comparator output signal is connected to microprocessor microcontroller 3, and single-chip microcomputer receives the output signal of comparer, carries out respective handling and moves for demonstration or to performer with output signal.But sensor 1 does not need to change at any time the resistance of adjustable resistance RW simultaneously at composition that detects material or content in this sensor signal processing circuit, manipulates inconvenience; And the resistance of adjustable resistance is difficult to accurate assurance, thereby the accuracy of detection of total system is reduced.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, detection signal accurate sensor signal processing circuit.
The utility model is achieved through the following technical solutions:
Design a kind of sensor signal processing circuit, comprise sensor and the single-chip microcomputer that is connected with sensor, in single-chip microcomputer, also be provided with the sensor signal processing module.
Sensor can be a gas sensor, also can be the sensor of other types.
The utility model compared with prior art has following remarkable advantage:
Sensor signal processing circuit provided by the utility model, abandoned in the prior art sensor signal output comparator circuit part extremely, directly sensor signal is caused in the sensor signal processing module that is provided with in the single-chip microcomputer, directly signal is carried out analyzing and processing by micro treatment module, improve the degree of accuracy of sensor circuit greatly, reduced the production cost of circuit.
Description of drawings
Fig. 1 is the schematic block circuit diagram of prior art;
Fig. 2 is a schematic block circuit diagram of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
With reference to shown in Figure 2, a kind of sensor signal processing circuit, sensor 1 can be detectors, also can be hydrodynamic pressure detection etc.The signal that sensor 1 is detected exports the sensor signal processing module 21 of single-chip microcomputer 3 to and carries out analyzing and processing, and the signal after the processing is moving for demonstration or to performer with output signal through respective handling.
The utility model is simple in structure, only need to increase a little processing module in existing single-chip microcomputer and get final product Substitute the comparator circuit of prior art, need not adjust adjustable resistance, the cost of both having saved has and has improved biography The certainty of measurement of sensor testing circuit.
Claims (2)
1, a kind of sensor signal processing circuit, the single-chip microcomputer (3) that comprises sensor (1) and be connected with sensor is characterized in that: also be provided with sensor signal processing module (21) in the described single-chip microcomputer.
2, sensor signal processing circuit according to claim 1 is characterized in that: described sensor is a gas sensor.
