Description
Technical field
The present invention relates to intelligent self-discipline centralized traffic control (CTC) system that disperses of railway, particularly a kind of data acquisition transmission and the equipment of handling (making station control is concentrated the self-discipline machine) that is used for the CTC system.
Background technology
A new generation disperses self-discipline centralized traffic control system (being called for short FZK-CTC), be under the new situation in the railway great-leap-forward development, computer technology, the communication technology, signalling technique is highly developed and the basis of DMIS system successful implementation on, a kind of later-model train traffic control that puts forward and signal control equipment also will bring a kind of new management pattern of organization of transportation efficiently simultaneously.The FZK-CTC of a new generation will carry out to the transportation management pattern of organization that structural rearrangement, function heavily draw, divide the work to reset, the post resets, and can realize that at the intermediate station that does not have passenger-cargo operation train traffic control is unmanned.After the cancellation of the relevant post of intermediate station train traffic control,, management close, operation-related according to specialty directly, rational principle is set, original post, function and mode of operation are adjusted again and are divided.
The FZK-CTC of a new generation has adopted the theory of disperseing self-discipline, promptly finish Core Features such as route gather, collision detection, control output by the station system, therefore, the station scheme Design of FZK-CTC is extremely crucial in whole a new generation disperses to restrain oneself the centralized traffic control system.
It is the station nucleus equipment that a new generation disperses self-discipline centralized traffic control system that making station control is concentrated self-discipline machine (being called for short LiRC), and its hardware belongs to special-purpose industrial grade computer equipment, at aspects such as reliability, data-handling capacities strict guarantee is arranged.The operating system of station self-discipline machine then is the real-time multi-task operating system of specific customization, in the software design, guarantee efficient, succinct, tight, and through complete comprehensive test.
The self-discipline machine scheme of at present domestic several big arterial railway signalling set producer has their own characteristics each, difference is bigger, probably can be divided into following three types: the one, adopt the special-purpose industrial computer scheme of cPCI structure; The 2nd, adopt common desk-top industrial computer scheme; The 3rd, the special machine scheme of employing particular design.The advantage of preceding two kinds of schemes is that available, ready-made resource is abundanter, and domestic industrial computer product is batch manufacturing, and optional leeway is bigger.Owing to directly select ready-made industrial computer hardware platform for use, the input on hardware just can be fewer during product development.So main energy only need be placed in the software development, thereby the single-piece development progress can be than comparatively fast.Simultaneously, when the market situation of system product was very not bright and clear, because hardware development is few, dropped into just fewer early stage self, is convenient to carry out cost control.Certainly, it also is very tangible adopting the shortcoming of special-purpose industrial computer of cPCI and general industrial computer, the one, and the industrial computer product is difficult to satisfy fully the applied environment and the functional requirement of railway signal system.The railway signal system interface device is many, and interface standard is different; The 2nd, signalling set is among the forceful electric power magnetic environment throughout the year, and is very high to electromagnetic compatibility requirements.Therefore, adopt general-duty industrial computer hardware platform scheme, aspect these two of the electromagnetic protections of Interface design and interface, run into great challenge.In addition, telltale is as the important component part of man-machine interaction, and is when adopting general-duty industrial computer hardware platform, because supporting liquid crystal or CRT monitor need take the bigger area of rack usually, very inconvenient when using at the scene.
Under above-mentioned background, the development goal of centralized traffic control self-discipline machine of new generation just seems clearer and more definite: at first be the requirement of wanting to satisfy systemic-function, this is realized by application software system that mainly the self-discipline machine provides hardware interface and operating system platform; The 2nd, at the complex electromagnetic environment that reality is faced, need provide the measure of certain actv. electromagnetic protection; The 3rd, need dexterity human-computer interaction interface easily.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of reliable and stable the data acquisition transmission and the equipment of handling that are used for railway CTC system for the defective that overcomes above-mentioned prior art existence.
