Reference numerals 1 and 2 in FIG. 1 are signal generators that limit the running speed of the train, and 3 and 4 are transmission lines that send signals to the iron rail and provide a speed limit signal to the upper side of the train.

In addition, 7 is the train's wheels and axles, which are elements that constitute a part of the transmission line, and 8 and 9 are on-board antenna parts, which have the function of inducing the speed limit signal flowing to the transmission lines 3 and 4.

界部での車上側受信機器への影響を調べることは
重要である。 At the boundary between the adjacent transmission lines 3 and 4, the signals from the signal generators 1 and 2 may be interrupted or overlapped for the antennas 8 and 9 on the vehicle top, as shown in Fig. 2. and received. The reception results from these adjacent parts may result in no signal for the onboard equipment, or one of them may receive a signal with a higher level, or as a result of a combination, it is determined that neither signal is the same. Therefore, it is important to investigate the effect on the on-vehicle receiving equipment at this boundary.

問題を有していた。 In this way, speed signals are transmitted from the ground side to the top of the train for security and automatic operation when trains are running, but in actual routes, speed signals are received on the top of the train near the boundaries of adjacent signal transmission paths. The operating state of equipment is unstable and transient, and therefore there has been a need for a test method that can test this in a stationary state. Furthermore, in new transportation systems, etc., there is a problem in that the operating state of receiving equipment on the vehicle cannot be known unless actual vehicle tests are carried out on actual tracks.

器等価試験方法を提供することを目的とする。 This invention was developed in view of the above points, and in order to equivalently test the influence of mutual signals on adjacent signal transmission lines on the ground side on an actual line, two transmission lines are arranged as a pair. By applying independent test signals to this transmission line at predetermined time intervals, it is possible to eliminate the need for actual vehicle tests on actual tracks, even in railways and new transportation systems that use rubber tires. It is an object of the present invention to provide an equivalent test method for on-board equipment for train control, which allows reception tests of on-board antennas in various overlapping states of nearby signals to be efficiently carried out in a stationary state.
