Abstract

The invention discloses an experimental data recording device and method and an experimental system, and the device comprises a radiation detection unit which collects electromagnetic waves in a laboratory and transmits electromagnetic signals corresponding to the collected electromagnetic waves to a main control unit; if it is determined that the electromagnetic intensity of the electromagnetic signal reaches a preset intensity threshold value, the main control unit receives and records experimental communication data, transmitted by the data interface, of the test equipment; and processing the experimental communication data of the test equipment under the condition that the electromagnetic intensity of the electromagnetic signal is within a preset test intensity interval to obtain corresponding relation information between the electromagnetic intensity of the electromagnetic signal and the experimental communication data of the test equipment under the preset test intensity interval. According to the scheme, the radiation detection unit and the main control unit are arranged to record and process the communication data of the test equipment such as the display equipment in the experiment process, so that lines which are easy to interfere in the data lines of the display equipment are checked according to the recorded data, and convenience and accuracy are achieved.
