Technical field
The utility model relates to sensing technology, gas detection monitoring field, specifically a kind of sensor detector.
Background technology
The quantity of present gas sensor test system and test sensor seldom, what have once can only test a sensor, testing efficiency is not high.Though what have can test a greater number, its build-out resistor or employing fixed resistance value, or need by artificial replacement, make that performance is relatively more difficult between the sensor.
The utility model content
The purpose of this utility model provides a kind of sensor detector, with solve existing multiple sensor can not be simultaneously with the problem of environment measurement.
The utility model comprises power supply, sensor, build-out resistor, computer control instruction transmission interface, and described sensor is divided into 8 group 16 the tunnel, every group of shared cover build-out resistor of two sensors; The positive pole of described power supply links to each other with the input end of sensor; The output terminal of sensor links to each other with the input end of build-out resistor, and the output terminal of build-out resistor links to each other with the negative pole of power supply; The control input end of build-out resistor links to each other with computer control instruction transmission interface interface by the resistors match control device.
The utility model principle: test macro adopts 16 tunnel circuit design, and every two-way is one group, and being divided into is 8 groups, because the shared cover build-out resistor of two sensors of every group of test circuit.16 road circuit start simultaneously when system works, simultaneously synchronous working.So it can realize the performance of two sensors under identical condition relatively.Build-out resistor between each group is chosen relatively independently, and its resistance is chosen and is independent of each other, and the performance during different build-out resistors coupling is relatively under equivalent environment can to reach a plurality of sensors.Same environment measurement when can realize multiple sensor has overcome the shortcoming that traditional measurement can only be measured a sensor at every turn.Increased the quantity of system testing sensor, promoted the testing efficiency of test macro greatly, saved the test duration widely sensor.
Below in conjunction with accompanying drawing the utility model is described in further detail.
