Abstract
The utility model relates to electric coded test equipment for testing a closed loop. A closed-loop electric coded technology can be used for testing a closed loop and effectively testing whether information is transmitted to a track indeed rather than testing the code sending fault caused by wire mixing or wire distributing fault. The electric coded test equipment is used for sending the code to electric coded interface equipment by an existing electric coded control circuit, the electric coded control circuit is used for sending carrier frequency information to a steel track, the electric coded interface equipment at another end is used for sending the carrier frequency information to track circuit receiving-end equipment, the track circuit receiving-end equipment is used for sending the carrier frequency information to shift frequency test equipment by an electric cable, and logical operation equipment is used for comparing the information to test the consistency. The electric coded test equipment can be used for timely testing whether train-carried information is existed in the steel track timely to discover the conditions of track breaking and code falling and avoid the compulsory brake of the train since the train-carried information can not be timely discovered to be existed in the steel track.
Description
Technical field
The utility model belongs to the railway signal technology field, is specifically related to a kind of coding checkout equipment of closed loop inspection.
Background technology
Existing railway in-station codification technology is owing to the stack that is two technology is synthetic; The two-layer skin problem of ubiquity; The locomotive signal information that system sends only is to be superimposed upon on the track circuit, and whether its information has sent on the track really, is not effectively detected; Existing detection alarm circuit just detects whether operate as normal of transmitting apparatus itself, and whether can not detect whole system operation intact.
The closed loop coding technology can realize that closed loop detects, and can whether send to track really to its information and effectively detect, but the signaling mistake that can not cause swinging cross or distribution mistake occurring is checked.
Summary of the invention
The purpose of the utility model provides whether the real-time omnidistance detection locomotive signal information of a kind of ability is sent to track really, also inspection sends to the information coding checkout equipment whether correct closed loop is checked on the rail.
The technical scheme that the utility model adopted is:
A kind of coding checkout equipment of closed loop inspection is characterized in that:
Include No. 1 coding interfacing equipment and No. 2 coding interfacing equipments;
Be connected with existing coding control circuit on No. 1 coding interfacing equipment, be connected with the coding transmitting apparatus on the existing coding control circuit, the coding transmitting apparatus is connected with logical operation equipment;
Be connected with track circuit on No. 2 coding interfacing equipments and receive end equipment, track circuit receives to be connected with on the end equipment shift frequency checkout equipment, and the shift frequency checkout equipment is connected with logical operation equipment;
Be connected with microcomputer interlocking on the logical operation equipment.
Adopt the serial communication mode to connect between described logical operation equipment and the microcomputer interlocking; Adopt serial communication or netting twine communication mode to connect between shift frequency checkout equipment and the logical operation equipment.
Be connected with panalarm on the described logical operation equipment.
The utlity model has following advantage:
The utility model can detect in the rail of track circuit whether do not have the train on-vehicle information in time, can in time find disconnected rail, fall the situation of sign indicating number; Logical operation equipment is checked information that self generates and the reception information that track circuit information, transmitting apparatus sent; Realize the closed loop inspection of ground on-vehicle information transmission; Thereby; Avoid the train forced brake that causes owing to no train on-vehicle information in the rail that can not find track circuit in time as much as possible, to greatest extent the driving accident that causes thus of minimizing.Compare with closed loop coding, the utility model need not be provided with relay, has reduced the distribution amount; Cost is low, and design, construction and maintenance are all comparatively simple.
Description of drawings

Among the figure, 1-1 coding interfacing equipment, 2-rail, the existing coding control circuit of 3-; 4-coding transmitting apparatus, 5-microcomputer interlocking, 6-shift frequency checkout equipment, 7-logical operation equipment; The 8-panalarm, the 9-track circuit receives end equipment, 10-2 coding interfacing equipment.
Embodiment
Below in conjunction with embodiment the utility model is carried out detailed explanation.
The coding checkout equipment of a kind of closed loop inspection that the utility model is related is provided with two coding interfacing equipments, and promptly No. 1 coding interfacing equipment 1 and No. 2 coding interfacing equipments 10 are connected on the rail 2.Be connected with the existing coding control circuit 3 that existing relay is encoded on No. 1 coding interfacing equipment 1, be connected with coding transmitting apparatus 4 on the existing coding control circuit 3, coding transmitting apparatus 4 is connected with logical operation equipment 7.Be connected with track circuit on No. 2 coding interfacing equipments 10 and receive end equipment 9, track circuit receives to be connected with on the end equipment 9 shift frequency checkout equipment 6, and shift frequency checkout equipment 6 is connected with logical operation equipment 7.Be connected with microcomputer interlocking 5 and panalarm 8 on the logical operation equipment 7.Adopt the serial communication mode to connect between logical operation equipment 7 and the microcomputer interlocking 5; Adopt serial communication or netting twine communication mode to connect between shift frequency checkout equipment 6 and the logical operation equipment 7.
Coding transmitting apparatus 4 through existing coding control circuit 3 to No. 1 coding interfacing equipment 1 signaling; Coding interfacing equipment 1 sends carrier frequency information to rail; At No. 2 coding interfacing equipments 10 of the other end carrier frequency information is passed to track circuit and receive end equipment 9, track circuit receives end equipment 9 through cable carrier frequency information to be passed to shift frequency checkout equipment 6.Logical operation equipment 7 obtains information needed such as turnover station teleseme LXJ, ZXJ, track section through the transmission medium that is connected with microcomputer interlocking 5 from microcomputer interlocking 5.Coding software in the logical operation equipment 7 is intact to carry out computing with the information that collects, and forms the coding of electronic code and the coding of existing relay coding and compares; When sending and receiving car route, 7 logical operations of logical operation equipment go out the code that should send at certain section of certain time, and like L, LU, U, HU, HB, UU, U2 etc., formation and coding design identical logic; When handling route, the information of logical operation software through collecting in the logical operation equipment 7 calculates each each track section of the moment of sending and receiving car route and should send the code of what frequency, and operation result should be the same with the coding circuit of relay coding.Carry out consistency check relatively with the shift frequency that obtains from shift frequency checkout equipment 6 and from the shift frequency that coding transmitting apparatus 4 obtains, inconsistently then provide warning, thereby check out that effectively distribution mistake, swinging cross, broken string cause the signal upgrading through panalarm 8; Whether not only can detect whether operate as normal of transmitting apparatus itself, it is intact to detect whole system operation.
