The utility model content
The purpose of the utility model provides a kind of pressure type temperature controller contact state of can gathering can gather a milliampere remote transfer signal value again, is that Temperature numerical is sent device through the data acquisition change that standard 101 stipulations send to industrial control host with the conversion of signals after gathering.
The technical solution that realizes the utility model purpose is following: a kind of pressure type temperature controller milliampere remote transfer signal has the Source Data Acquisition change to send device; Comprise mainboard in assume diamond in shape box-like shell 1 and the shell; The said upper end that assumes diamond in shape box-like shell is provided with 6 way switch contacts; Be numbered S1, S2, S3, S4, S5, S6, said mainboard is provided with analog signal conditioner circuit, AD sample circuit, switch acquisition circuit, single-chip microcomputer, RS232 interface; The analog signal conditioner circuit is connected with the AD sample circuit through spi bus, and the AD sample circuit is connected with single-chip microcomputer through bus; Single-chip microcomputer is connected with the switch acquisition circuit with filtering circuit through the level isolation.This device in single-chip microcomputer instruction down, the temperature controller data that once collected to the industrial control host transmission in per 0.5 second with 9600 fixedly baud rate.Also be provided with milliampere remote transfer signal and gather contact, be numbered 61,62, be provided with 24V WV contact, be numbered 63; Be connected with the switch acquisition circuit through mainboard; The RS232 interface 4 of box-like shell 1 lower end of assuming diamond in shape is connected with industrial control host through data line.
This device to the milliampere resistance teletransmission output signal of temperature controller promptly the resistance value between 61 and 62 gather, numbering 63 contact is the 24V WV contact that provides for temperature controller; Insert the make and break contact loop of tested temperature controller simultaneously, the main processing block of working value, rreturn value, the switch changed position situation of switch motion being delivered to industrial control host through communication carries out unified processing to above-mentioned data; With the conversion of signals after gathering is that Temperature numerical sends to industrial control host through standard 101 stipulations.
Compared with prior art, this novel beneficial effect shows:
1, this Design of device and employing have realized idea that the basic calibration points of temperature controller and contact verification are carried out simultaneously the temperature controller verification working time having been shortened 50%.
2, realize data acquisition and temperature transmitter integratedly first, realize becoming temperature value to pass to industrial control host the milliampere data-switching with software.Can checking precision and verification efficient have been improved so that testing crew when having overcome daily manual verification, is converted into the error that causes after the temperature with the milliampere value like this.
3, this data acquisition unit is designed to active type, can provide for temperature controller+the 24V working power, and this method not only can reduce wiring, also can practice thrift a power supply changeover device that converts 220V into 24V, also can effectively reduce potential safety hazard.
