utility model content:
the purpose of this utility model is to provide a kind of multiple sensor signals acquisition processing device.
above-mentioned object is realized by following technical scheme:
a kind of multiple sensor signals acquisition processing device, its composition comprises: Metal shielding shell, described Metal shielding shell is built with pcb board, described pcb board is equipped with input interface, described input interface is electrically connected with power module, and described power module is electrically connected with decoupling capacitor, and described decoupling capacitor is electrically connected with differential amplifier, described differential amplifier is electrically connected respectively with sensor group and shunt capacitance, and described shunt capacitance is electrically connected with output interface.
described multiple sensor signals acquisition processing device, described power module, described decoupling capacitor, described differential amplifier, described shunt capacitance, described output interface are all contained on described pcb board, and it is outside that described sensor group is arranged on described Metal shielding shell; Described sensor group comprises temperature sensor, humidity sensor, seal sensor, pressure transducer.
beneficial effect:
1. when the utility model uses, described sensor group is placed on the relevant position needing the equipment carrying out information acquisition, input interface and output interface are electrically connected with supporting messaging device, after switching on power, the various information of equipment by after the collection of sensor group through being transferred to messaging device by after differential amplifier process; The decoupling capacitor be electrically connected with power module helps the electric current of circuit with stable, and the radio-frequency component be mixed with in the alternating current of high-frequency current and low-frequency current filters by shunt capacitance.
the utility model have employed the differential amplifier circuit of restraint speckle, and voltage gain is less, effectively the amplification of restraint speckle signal, so the prestage being used in amplifying circuit can obtain low-noise characteristic; When PCB plate makes, input and output are directly received on circuit board, input and output signal is made directly to deliver to circuit board and output, shorten input and output line, cut down the number of intermediate links, vital role is served to reduction noise and good input, output signal.
the utility model have employed Metal shielding shell shielding, shielding external interference that can be good, and does good ground connection, have employed the interference of decoupling capacitor and shunt capacitance suppression power supply simultaneously.
