The invention discloses a virtual
program control temperature test instrument and belongs to the technical field of mechanical and electrical product test. The instrument mainly comprises an upper computer, a power supply module, a temperature sensor, a
signal conditioning module, a singlechip and a
serial port server, wherein the temperature sensor consists of a 24-path K-type thermal electric couple; a
signal acquired by the thermal electric couple is amplified by the
signal conditioning module and is subjected to cold junction compensation and A / D conversion to generate a temperature
digital signal to be stored in the
internal memory of the singlechip; a temperature value is transmitted to the
serial port server through a
serial port of the singlechip; and the serial port
server converts a serial port signal into an
Ethernet signal so as to realize
remote communication with the upper computer. The
software of the upper computer automatically judges whether temperature rise is accordant with a standard and realizes setting of a temperature acquisition frequency, the definition of a temperature channel, real-time display of a temperature test value, drawing of a
temperature curve and automatic generation of a
test report. The test instrument has a simple test form, can improve the intellectuality, accuracy and reliability of a
system and meets the requirements of current networked tests.
