The novel purpose of this use is to overcome the defective that exists in the prior art, and a kind of integrated key that can make accuracy that key measures mutually and reliability better effects if transmitter mutually is provided.
For achieving the above object, the technical scheme of the utility model provides a kind of integrated key phase transmitter, comprising:
Detecting signal unit comprises being arranged near the mutually sensor of key to be detected, is used for the acquisition pulse signal, and pulse signal is sent to signal processing unit;
Signal processing unit; Comprise the filtering circuit, comparison shaping circuit and the single-chip microcomputer that are connected in turn on the circuit board; Be used to receive the pulse signal that detecting signal unit sends; And said pulse signal handled, through output terminal result is sent to first delivery unit and/or second delivery unit then;
First output unit is exported the pulse signal of receiving signal processing unit through photoisolator and impact damper;
Second output unit converts the pulse signal of receiving signal processing unit into current signal output through photoisolator, digital to analog converter and converter successively.
For the ease of measuring a plurality of key phase parts in a plurality of key phase equipment or same the equipment; Optimized technical scheme; Be that described sensor has one at least, also can use a plurality of of the same type or sensors of various types, can use current vortex sensor like said sensor.
In order to protect the normal operation of transmitter, further optimized technical scheme is, said transmitter also comprises power module, is used to each unit power supply.
For transmitter is not destroyed; Further optimized technical scheme is; Comprise housing; Said signal processing unit, first output unit and second output unit are arranged in the housing, on the panel of said housing, are provided with the interface that connects detecting signal unit, are provided with the first output unit interface, second output unit interface and the reset key.
The advantage of the utility model is with beneficial effect: this integrated key transmitter mutually adopts advanced integrated electronic circuit, has and monitors accuracy and reliability preferably; Because sensor can be a plurality of, can measure a plurality of key phase parts in a plurality of key phase equipment or same the equipment; Owing to comprise and can play a protective role housing to transmitter.
