TT＆C software on calculation machine is completed, without the correlation manual operation such as manually opened equipment or controlling opening of valve.The software is also protected with self simultaneously
Protective function, all test parameters in system are provided with the higher limit of alarm, if there is relevant parameter to exceed the situation of the higher limit in test process
Occur, alarm screen is will appear from TT＆C software, point out the particular content of alarm, and alarm signal is sent to PLC by serial communication
The corresponding buzzer warning of control.Can artificially select to continue test experiments when alarm occurs, also be off experiment, if occurring 3 minutes in alarm
Afterwards still without related operation, be stopped for the power-off of whole machine, tester shielded by test system.
7. the TT＆C software of the master station computer in the collection of soil thermal physical property data and apparatus control system is integrated with test pattern selecting module, can carry out
Various test patterns, such as invariable power follow-on test, stationary temperature follow-on test, discontinuity test and inactivity test.Or in test process, from
The Changing Pattern for defining test is tested, and the influence of the heat exchange property under different operating modes to underground heat exchange system is probed into this.
Beneficial effects of the present invention are as follows：
(1) soil thermal property test is completed with the VISA Serial Communications and PLC free-port communications technology of advanced graphical programming software
During parameters data acquisition with automatically save, and completion tester is automatically controlled, reduce tester labour intensity, while
Surrounding environment be it also avoid for the influence tested, test accuracy is greatly improved, the self-protection of tester itself also has certain guarantee,
Prevent fortuitous event from occurring.
(2) based on the integrated of remote monitoring module, site testing data can be checked and is operated at any time, be waited for for a long time without tester
In test site.
