Abstract
The utility model discloses a multistation radio transmission dash testing device, and the utility model solves the problem that the existing dash testing device has inconvenient usage and inaccurate testing. The utility model includes a main machine. Two groups of photoelectric emission modules and photoelectric reception modules, a control module and a radio emission module are arranged at the position of the end point. The main machine is made up by a control part and a wireless reception part. The control module, the radio emission module and the photoelectric reception modules are arranged in the middle of the two groups of photoelectric emission modules. The photoelectric emission modules emit photoelectric signals. When no testers pass through the end point, the photoelectric reception modules can receive the photoelectric signals continuously. When the tester passes through the end point, and the photoelectric signals are intercepted, the control module controls the encodes of the testers by which the photoelectric signals are intercepted which are emitted by the radio emission module. The wireless reception part receives the encodes emitted by the radio emission module. Through decoding, the data is input to the control part. The control part judges the sequence and the testing time that the tester reaches the end point.
