Problems solved by technology
[0003] In the prior art, because the voltage level of the digital control signal of the diesel locomotive is inconsistent with the voltage level of the digital control signal acquisition module of the current electric locomotive, it cannot meet the needs of the internal power reconnection control and cannot handle the increased internal power reconnection. The control signal output by the coupling conversion device is detected, so that the operation safety of electric locomotives and diesel locomotives cannot be guaranteed accordingly

The invention discloses an internal electric reconnection control signal collecting device which is built in an electric locomotive control system. The system comprises a central processing unit, a digital value input and output device and an internal electric reconnection signal converting device which are sequentially connected, wherein the signal collecting device is connected with the internalelectric reconnection signal converting device and a central control unit, receives a plurality of internal electric reconnection control signals output by the internal electric reconnection signal converting device and matched with an internal electric reconnection signal transmitting cable at the interval of collecting time, converts the internal electric reconnection control signals into feedback signal data corresponding to the internal electric reconnection control signals one to one through a multifunctional vehicle bus, and sends the feedback signal data transmitted to a diesel locomotive control system to the central control unit. The purpose of collecting internal electric reconnection control signals is achieved, the monitoring and diagnosis method of the internal electric reconnection control signals is formulated, and the operating safety guarantee of an internal electric reconnection marshalling locomotive is achieved.
Description
technical field [0001] The invention relates to the field of multiple locomotive reconnection marshalling, in particular to an internal electric reconnection control signal acquisition device for electric locomotive marshalling to control diesel locomotive marshalling and a diagnostic method thereof. Background technique [0002] With the rapid development of railway technology, heavy-duty has become an important development direction in the field of rail transit. In order to haul heavier cargo, electric locomotives form multi-machine reconnection groups through twisted train buses. At present, this technology is in the domestic market. has been widely used outside. In fact, electric locomotives are not limited to being reconnected with electric locomotives through the twisted train bus, electric locomotives can also be reconnected with diesel locomotives through hard wires that meet the AAR S-512 standard, so it can be used without changing the hardware of diesel locomotive...
