The invention discloses a relay contact detection device, and the device comprises a drive circuit which is used for receiving the electric energy of a first power supply, and outputting a first electric signal according to the control rule of a controller; the self-checking circuit is used for transmitting the first electric signal to a first contact of the tested relay when the self-checking circuit is in a non-self-checking state; the controller is used for realizing self-inspection of the relay contact detection device when the self-inspection circuit is controlled to be in a self-inspection state; after the self-checking circuit is controlled to be in a non-self-checking state, whether the first electric signal is received through the input channel acquisition circuit or not is judged, if yes, it is determined that the first contact and the second contact of the tested relay are in a conduction state, and if not, it is determined that the first contact and the second contact of the tested relay are in a disconnection state; and an input channel acquisition circuit. By applying the scheme of the invention, the accuracy of detecting the contact state of the relay can be effectively improved. The invention further provides a train signal control system which has corresponding effects.

    本申请公开了一种继电器触点检测装置,包括:驱动电路,用于接收第一电源的电能,并按照控制器的控制规则输出第一电信号;自检电路,用于当自身为非自检状态时,将第一电信号传输至被测继电器的第一触点;控制器,用于在控制自检电路为自检状态时实现继电器触点检测装置的自检;在控制自检电路为非自检状态之后,判断是否通过输入通道采集电路接收到第一电信号,如果是,则确定出被测继电器的第一触点和第二触点之间为导通状态,如果否,则确定出被测继电器的第一触点和第二触点之间为关断状态;输入通道采集电路。应用本申请的方案,可以有效地提高检测继电器触点状态时的准确性。本申请还提供了一种列车信号控制系统,具有相应效果。
