Description
Technical field
The utility model belongs to the chromacoder in comprehensive operation vehicle, relates in particular to the device of voltage swing conversion between comprehensive operation vehicle and mobile unit.
Background technology
Comprehensive operation vehicle and railcar are mainly used in the task such as electrification maintenance, emergency repair rescue on high-speed railway.Comprehensive operation vehicle is single-unit marshalling, vehicle commander is about 18m, in order to better realize the mutual of LKJ and ATP information, ATP car controlling exports usual instructions, unloading can not be exported with urgent, comprehensive operation vehicle can reach operation field fast, carries out rapidly the tasks such as multifunctional comprehensive operation, site examining and repairing, emergency repair rescue.But the working condition signal of comprehensive operation vehicle, key signal are DC24V, the interface signal of mobile unit (ATP and LKJ) is DC110V, therefore the device of an increase voltage transitions is needed, the DC24V signal provided by vehicle is converted to DC110V signal, be installed in the LKJ of comprehensive operation vehicle, use the H type monitoring host computer in prime mover group.
Utility model content
The problem that the utility model solves is for providing one between comprehensive operation vehicle and mobile unit for the chromacoder of voltage transitions, can normal working communication between the comprehensive operation vehicle making voltage different and mobile unit.
The utility model is achieved through the following technical solutions:
A kind of chromacoder realizing voltage signal conversion, chromacoder is between ATP equipment and LKJ equipment, the 12 road signals from ATP equipment or LKJ equipment enter 12 tunnel signal conversion processes unit respectively, each signal conversion processes unit includes the transient voltage suppression circuit and filter circuit that are connected successively, the output of described filter circuit connects voltage conversion circuit, and is equipped with LED indicating circuit in each road signal conversion processes unit.
Described transient voltage suppression circuit includes Transient Suppression Diode, diode, resistance, electric capacity, and diode and resistance parallel circuits after connecting and electric capacity are contacted and formed series circuit, and Transient Suppression Diode is in parallel with described series circuit.
Described filter circuit is RC filter circuit.
The utility model has following beneficial effect: the interface signal of the DC110V of the signal of the DC24V of comprehensive operation vehicle and mobile unit can couple together by the utility model, namely provides 8 tunnels 24V to be changed the ability of 110V; 110V is changed the ability of 24V by 4 tunnels, and then realizes the communication between comprehensive operation vehicle and mobile unit.
Accompanying drawing explanation
Fig. 1 is theory structure schematic diagram of the present utility model.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of chromacoder realizing voltage signal conversion, chromacoder is between ATP equipment and LKJ equipment, the 12 road signals from ATP equipment or LKJ equipment enter 12 tunnel signal conversion processes unit respectively, each signal conversion processes unit includes the transient voltage suppression circuit and filter circuit that are connected successively, the output of filter circuit connects voltage conversion circuit, and is equipped with LED indicating circuit in each road signal conversion processes unit.
Rated voltage DC24V, voltage change range DC16.8V-30V; Rated voltage DC110V, voltage change range DC77V-137.5V.
Chromacoder is mainly used in the conversion of 24V and 110V voltage signal, is mainly installed on synthetic detection vehicle at present, uses with LKJ equipment/ATP coordinative composition of equipments.Device adopts CT63 series electric connector to be external interface, device is designed with ST1T, ST2T two interfaces, and ST1T interface connects locomotive 24V working condition signal and 24V unloading output signal arrives ATP device; ST2T connects LKJ main frame and exports 110V working condition signal and unloader signal.Chromacoder matches with CTCS2-200T equipment entrucking, and can not install chromacoder during the entrucking of CTCS2-200H equipment, the system block diagram of scheme asks for an interview accompanying drawing 1.
Above-mentioned every road transient voltage suppression circuit all includes Transient Suppression Diode, diode, resistance, electric capacity, and diode and resistance parallel circuits after connecting and electric capacity are contacted and formed series circuit, and Transient Suppression Diode is in parallel with described series circuit.As shown in Figure 2, in an embodiment of the present utility model, Transient Suppression Diode model is SMBJ30A.
Above-mentioned filter circuit is RC filter circuit.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and be implemented, can not limit protection range of the present utility model with this.In addition to the implementation, the utility model can also have other execution modes, and all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection range of the present utility model.
