Description
Technical field
The utility model relates to a kind of equipment for the railroad train operation monitoring.
Background technology
The LKJ train operation monitoring and recording device is to ensure that train operating safety is the train speed control device of fundamental purpose, is bringing into play significant effect aspect guarantee railway safety and the safety management of propelling engineering.LKJ adopts track data to be stored in the vehicle-mounted data storehouse fully, rely on the reasoning address to transfer track data, this mode can make the demand of ground car information reduce greatly, the situation of flexible adaptation Chinese Railway track data complexity, but for any physical change of circuit, all need to change the vehicle-mounted data of LKJ.
In recent years, great-leap-forward development along with railway, new line is built, the rebuilding construction of old circuit is more and more, and LKJ2000 monitoring record board package can not satisfy the needs that railway high speed develops at aspects such as online updating maintenances of program, data, ground data storage space, data check mode, plug-in unit maintenance managements.Specifically describe as follows:
(1) program/data update mode
The monitoring record plug-in unit is the core component of system as the host module of monitor recording device.Mainly finish the ground line data storage and call, the record of running state data with synchronously, the calculating of control model, the generation of real-time clock, and realize control and management to other modules of system by internal bus.Plug-in unit is not considered relevant renewal controlling mechanism in design, original program and track data adopt the mode of EPROM chip-stored simultaneously, also limited the use of this mode, when at present system program and data being safeguarded, need dismantle device EPROM is taken out, wipe and reprogramming at special programmed circuit, according to the 44th regulation of the [2006] No. 88 file chapter 5 of the Ministry of Railways: use quality for guaranteeing supervising device, the erasable number of times of storage line circuit-switched data chip should be above 5 times.About 100 yuan of the EPROM chip of a slice 1MB shares 4 in the LKJ2000 type main frame, about 400 yuan.Be to calculate for 5 times by the replacing number of times of annual cross-channel data, about 2000 yuan of the cost of track data chip is added the replacing of program chip, and use cost is expensive, causes the waste of a large amount of human and material resources.
(2) data storage capacity
LKJ2000 type monitor recording device is at the beginning of design, and the memory capacity of watchdog routine and ground data is 1MB, uses two EPROM to store, and along with starting of railway speed raising and direct express train train, the data capacity of 1MB can not meet the demands far away.Particularly for the passenger vehicle long routing, the lorry section of the striding office of striding uses, and requires locomotive operation to use unique monitor data, to make things convenient for interoffice and intersegmental exchanges data.For the more Railway Bureau of cross-channel, namely be by the software and hardware transformation to original monitoring record plug-in unit, data storage capacity is promoted to 2MB, can not satisfy request for utilization.Some Railway Bureau implements by data chip of passenger vehicle, data chip of lorry at present, has brought great inconvenience to monitoring management.
(3) verification mode
Arithmetic capability in view of MC68332, the major part of LKJ adopts the mode of verification and verification at present, such as the power on of program, data, the exchange of active and standby machine synchrodata etc., find the error detecing capability wretched insufficiency of verification and mode in using at the scene, cause error in data to use, but the CRC check mode that working strength is higher, existing plug-in unit need to expend a large amount of time, thus the real-time of impact monitoring.
(4) plug-in management
Original plug-in unit is not considered the validity management to plug-in unit when design, a large amount of uses along with supervising device, some producers are for seeking profit, the phenomenon that a large amount of anti-manufacturers processed monitoring plug-in unit occurs, because these manufacturer production techniques fall behind, the material procurement channel is complicated, be difficult to guarantee the quality of production of plug-in unit, brought potential safety hazard to train operation.
Summary of the invention
The purpose of this utility model provides a kind of accurately monitoring record plug-in unit of routine data updating maintenance, raising data storage capacity and assurance renewal data security that makes things convenient for.
For achieving the above object, the utility model is by the following technical solutions:
A kind of monitoring record plug-in unit, described monitoring record plug-in unit obtains more new data from routine data is updated the equipment, more new data is sent among the CPU of monitoring record plug-in unit, CPU will be more new data send into and carry out verification in the CRC processing unit, the more new data after the verification deposits in the routine data storage unit; Simultaneously, the renewal data communication device of CPU after with verification crossed interface and sent.
Described CPU obtains more new data by USB interface or RS232 interface.
Described CPU sends by VME interface, synchronous communication interface or the CAN bus interface more new data after with verification.
Adopt the utility model of technique scheme, have the following advantages:
1) software compatibility is strong, is convenient to management
Application program and ground data that the compatible existing LKJ2000 host monitor record plug-in unit of LKJ2000 host monitor record H plug-in unit newly developed uses, vehicle-mounted software is consistent with the software on ground version when LKJ2000 type train operation monitoring and recording device is upgraded, and is convenient to unified management; And LKJ2000 host monitor record H plug-in unit primary processor also adopts motorola mc68332, identical with LKJ2000 host monitor record plug-in unit at core circuit, peripheral interface, can directly substitute original monitoring record plug-in unit work, be convenient to the unified standard management of motorcycle safety equipment, directly use simultaneously LKJ2000 application program and the data of successfully having used in system-wide, the risk of having avoided program newly developed to exist.
2) online programming of support program, data
LKJ2000 host monitor record plug-in unit adopts EPROM storage program and data, need when system program and data are upgraded dismantle device EPROM is taken out, wipe and reprogramming at special programmed circuit, this kind update mechanism, on the one hand because the continuous plug of monitoring plug-in unit causes relevant connector contact loosening, cause the hidden danger on the safety, each data maintenance all can cause the waste of a large amount of human and material resources on the other hand.LKJ2000 host monitor record H plug-in unit adopts flash as program, data storage medium, program, online data renewal controlling mechanism have been increased, online programming device by special use, finish the online programming of flash, the record of automatically being correlated with, file for future examination, and the online updating of program, data uses special use to update the equipment, and ensures the security of refresh routine and data.
3) large storage space satisfies the long routing needs
Original plate carries the primary control program space and is 1M to the maximum, the ground data space is 2MB to the maximum, the maximum 2M in train operation state record data space, railway high speed and long routing can not have been satisfied to the unified requirement of system-wide data, LKJ2000 host monitor record H plug-in unit adopts 2 32MB flash as vehicle-mounted data and record data storage medium, 1 32MB flash is as the storage space of boot and application program, wherein make plate carry the ground data storage space and expanded 47M, train operation state record data storage space has expanded 16M, improves the availability of LKJ2000 type train operation monitoring and recording device.
4) has the CRC operation processing unit
Have the CRC operation processing unit at H type monitoring record plug-in unit, improve the security of usage data.
5) has the ID recognition function
