Description
[technical field]
The utility model relates to the railway electronic equipment, specifically relates to a kind of multisensor syste that is applied to motor-car base or motor-car that utilization is carried out location.
[background technology]
According to China Railway High-speed net construction plan, national provincial capital and railway terminal city are supporting overhaul of train-set base of EMUs or motor-car utilization institute constantly building.
The following several parts of overhaul of train-set base or motor-car utilization reason are formed: throat, bicycle parking factory, washing track, one-level repair that the storehouse is repaiied in storehouse, secondary Xiu Ku, three level Four, Pyatyi is repaiied the storehouse.
In maintenance of EMUs vehicle and maintenance process, be divided into:
One-level is repaiied: move 4000 kilometers or 48 hours and carry out once utilization overhaul comprehensively;
Secondary is repaiied: move 30,000 kilometers or 30 days and carry out once special maintenance;
Repair for three grades: accumulative total is moved 450,000 kilometers or 1 year;
Level Four is repaiied: accumulative total is moved 900,000 kilometers or 3 years;
Pyatyi is repaiied: accumulative total is moved 1,800,000 kilometers or 6 years;
Investigate China in Beijing of building, Shanghai, 4 the overhaul of train-set bases in Wuhan and Guangzhou, following common characteristic is all arranged:
1. in large scale, rationally distributed (motor car inspection and repair base, Beijing is taken up an area of 1800 mu);
2. overhaul vehicle numerous (bicycle parking ability 70 row, service ability at different levels 20 row);
3. maintenance vehicle (CRH1, CRH2, CRH3, CRH5, CRH380A etc.) is more;
4. vehicle is shunt frequent in maintenance base or motor-car institute;
5. weather conditions differ greatly;
Base scheduling at present mainly depends on comprehensive video and manual type motor-car parking maintenance such as bicycle parking factory, maintenance at different levels storehouse and schedule is dispatched.
Therefore need more science, efficient, the motor-car location positioning system is accomplished following function reliably:
1, EMUs get into the identification in maintenance base.Promptly begin position from throat, and can follow the tracks of and locate with regard to the perception motor-car at motor-car.
2, can accomplish that current maintenance base motor-car is respectively deposited, passed through, the comprehensive tracking and the inquiry of job state.
Can the motor-car positional information be represented to scheduling, operating personnel through interface intuitively and use.
Can store the foundation of each motor-car position history information as further optimization work.
According to the interior over the next several years further requirement to EMUs tracking and position of the demand and motor car inspection and repair base, we design and have accomplished new EMUs tracking and location positioning system.
Also have at present towards the motor-car in motor-car base and follow the trail of and location positioning system, but comprehensively examine these systems to have following shortcoming:
Shortcoming 1: the EMUs operation information obtains microcomputer interlocking (monitoring) information that depends on.
In the daily production work of EMUs, microcomputer interlocking (monitoring) information belongs to high-level, confidentiality information.Microcomputer interlocking belongs to independently system simultaneously, is difficult for producing the relevance relation with external system.So EMUs location tracking information obtain from lock file reliability, independence, the exploitativeness that obtains to be unfavorable for the location tracking system.
EMUs are followed the trail of with location positioning system should belong to fully independently that information is obtained, transmission, treatment system, just can ensure extensive use in all parts of the country thus.
Shortcoming 2: the EMUs identity information depends on RF ID (radio frequency identification) technology.
Under EMUs CRH1, CRH2 type car, an active RF tag has been installed; Need carry out simultaneously the position of identification at throat etc.; RF ID card reader is installed, when vehicle through the time can read the label information under this vehicle, thereby can confirm testing vehicle register.
Use the RFID mode to confirm that EMUs identity price is higher, each station track is about 40,000 RMB, and RFID reader device complex structure is unfavorable for later maintenance simultaneously.
Shortcoming 3:CRH3, CRH380A do not install label card.
Make newly at present that CRH3 does not install label card in the motor train unit train of 350 kilometers of speed per hours, novel EMUs such as CRH380A are not all installed this label card.
So based on the EMUs tracking of RFID recognition technology and the system of location positioning bigger defective is arranged, can not accomplish EMUs simultaneously and follow the trail of and location positioning work.
Shortcoming 4: existing system exists multiple bus structures and heterogeneous network system.
Have multiple bus and network systems such as RS485, RS232, CAN, TCP/IP in existing EMUs tracking and the location positioning system, and these heterogeneous network systems just can insert the netscape messaging server Netscape based on x86 after all need transferring.Too much heterogeneous network system is unfavorable for system construction, maintenance and reliability service.
Shortcoming 5: existing system fault-free remote inquiry and fault teleprocessing function.
Can't be in the existing system through the operating state of each transducer of long-range acquisition, field apparatus; After going wrong simultaneously, can't come handling failure through long-range.
This system needs 7 * 24 mode of operations, and the turnover motor-car base of EMUs all possibly take place in 7 * 24 simultaneously, so this system must complete errorless reliability service.Can hardly be avoided but break down in the reality, how in time to find fault after breaking down, in time handling failure is of crucial importance with regard to what become simultaneously.
Shortcoming 6: each transducer of existing system uses star-like connection.
Each position transducer uses the Y-connection mode in the existing system, is unfavorable for system wiring and maintenance.Because the motor-car area of base is huge, need to use a large amount of position transducers, use the Y-connection mode can increase the capital construction amount, increase the system wiring difficulty.Star system is unfavorable for system implementation and maintenance simultaneously.
Shortcoming 7: each position transducer of existing system uses switching value to export as state.
Each position transducer uses single switching value to export as state in the existing system.Promptly use a certain level to represent that the place ahead has motor-car to park, use an other level to represent not have motor-car to park.Along with the growth of service time, sensing system can wear out, and the output of switching value is that judgement is just exported through threshold values.Maintenance system can't obtain transducer ageing state and suitable adjusting threshold values, thereby has increased system failure probability and maintenance difficulties.
Use the unidirectional output of switching value simultaneously, and can not input information, control centre uncontrollable with revision working sensor state.
