Abstract

The invention provides heater unit temperature field acquisition test equipment based on a PLC; the equipment mainly comprises a draw-bar box; a power supply, a touch screen, the PLC, a plurality of temperature sensors and a plurality of paths of temperature acquisition modules are arranged in the draw-bar box; all electric parts are integrated on one mounting plate, and embedded and fixed in thedraw-bar box; a switch power supply converts the commercial power AC 220V into a DC 24 V power supply through an AC / DC converter, thus powering up the touch screen and the PLC. The temperature sensorsgather the heater unit temperature field surface temperature; the temperature acquisition modules can upload the gathered data to the PLC; the touch screen stores and outputs the temperature of eachacquisition point and a change curve. The test equipment is simple and compact in structure, controllable in period, good in reliability, easy to control, and can realize multi-point real time data acquisition, thus greatly improving the heater unit temperature field test verification efficiency.

Description

technical field [0001] The invention relates to the technical field of temperature acquisition, in particular to a PLC-based acquisition test equipment for the temperature field of a heater. Background technique [0002] In the industrial production process, temperature is one of the most common and important physical process parameters. With the development of society, the requirements for temperature measurement in industry are getting higher and higher, and the range of measurement data is also increasing. [0003] The heater directly heats the heating wire to make the air temperature rise, and through the rotation of the fan, the air is circulated to make the indoor temperature rise, and the temperature signal is collected through the NTC, and the appropriate temperature control method is used to achieve the desired temperature. The traditional heater temperature test equipment is a hand-held temperature tester, which cannot perform multi-channel acquisition at the same...
