Description
Technical field
The invention belongs to the vehicle-mounted broadcasting system regions of track traffic, and in particular to a kind of new dynamic map denotation system
System.
Background technology
Track traffic does not only have communications and transportation attribute, while also has Name card of city and media and communications attribute concurrently.Traditional LED
Dynamic map has the shortcomings that single display information, poor expandability, can not realize movement across lines, can not meet current orbit
The demand of traffic operation pattern.And LCD dynamic map display systems can realize high-resolution, digital information transmission, multiple solutions
Multi information is shown, passenger can be allowed to be in closing space and remain to keep the information interchange with the external world constantly, fully demonstrate public affairs
Traffic is people-oriented using passenger as this service theory altogether.System can be realized to management and issue of the multi-source to type information,
And multi-source, multiple terminals, information that is parallel, having priority to arrange can be issued.Conventional information type includes small data
The text message of amount and the media information of big data quantity.Text message includes train line relevant information, website relevant information, row
The relevant informations such as car running status relevant information, emergency related information, traffic transfer.Media-related information is included dynamically
Figure designated identification information, advertising message etc..Any of the above information is moved according to the needs of train operation according to logical triggering in LCD
Rationally shown on state map screen, the demand of the visual perception of the passenger more met on the basis of complete running information shows.
Most of all, for circuit extension and train movement across lines problem, traditional LED dynamic maps solution is only
Have and change dynamic map pad pasting or dynamic map integral replacing, for LCD dynamic map solutions, only need simple software
Configuration can be settled easily.The plurality of advantages of LCD dynamic maps makes LCD dynamic map solutions increasingly be transported by track traffic
The favor of company of battalion.
What dynamic map implementation was conventional at present mainly has two kinds of directions：Centralized Control and LCD independent controls.
A. centralized Control
As shown in figure 1, centralized Control sets LCD dynamic maps master controller to complete the LCD of permutation car in drivers' cab
The centralized Control of dynamic map display screen.LCD dynamic map master controllers receive row control information, and according to it is default dynamically
Figure displaying scheme, extract corresponding video media information and synthesized, through train looped network after compressed encoding in the form of MPEG4/2
Transmit to each guest room LCD display.Shown inside guest room LCD display by video solution and A/D conversion driving LCD liquid crystal displays.
B. independent control
Storage, information synthesis, video control and video are internally integrated it as shown in Fig. 2 independent control is LCD and the mould such as show
Block, row control information is received by network or 485 buses, the corresponding multimedia messages of storage inside are called according to default logic,
It is autonomous to realize multidate information processing and display function.
Centralized Control and independent control comparison：
1. in terms of redundancy, independent control is better than centralized Control.Centralized Control realizes control by a lcd controller is unified
System, once controller failure will influence the LCD display of permutation car.For independent control, single screen failure, other displays
Shield unaffected.
2. in terms of later maintenance upgrading, centralized Control is better than independent control.For maintenance upgrade, centralized Control only needs pair
LCD master controllers carry out upgrade maintenance, and independent control will be updated upgrading to all LCD screens.
3. in terms of cost：Centralized Control is better than independent control.For centralized Control, LCD screen need to only realize display function, and
Independent control LCD screen need to have a sophisticated functions such as signal transacting, Video Composition, and cost is of a relatively high.
For current LCD dynamic map display systems development trend, the present invention proposes a kind of new dynamic map denotation
Scheme, using a kind of distributed central control mode.
The content of the invention

RS485 buses connect train PA master controls and receive its row control information issued, the left side of the control centering and right side LCD dynamics
Map master control connects corresponding first LCD display in left side and right side, guest room in guest room respectively by differential signal delivery outlet
Left side and right side are respectively symmetrically provided with polylith LCD display, are connected with each other between the LCD display per side by cascade system,
Each LCD dynamic maps master control of the control centering is connected to train Ethernet, each LCD dynamic maps master by interchanger
Control is solidified with unique IP address, and the video information received by corresponding IP address realizes that the LCD at left and right sides of each guest room shows
Display screen mirror image is shown.
Further, each LCD dynamic maps master control of the control centering is regarded using the output of the differential video way of output
Frequently.
Further, the row control information includes terminus, inception point, when next stop, the next stop, enabling side, broadcast type
And running state information, each LCD dynamic maps master control of the control centering intercept corresponding word in RS485 buses according to agreement
The row control information of section, it is automatic to trigger the corresponding dispaly state of dynamic map, and LCD is output to by the differential video way of output and shown
Display screen is shown.
Further, the LCD display is realized by A/D boards and cascaded.
Further, the LCD display realizes Bypass functions by A/D boards, and LCD display hardware and software failure is certainly
Dynamic to trigger its Bypass function, input/output signal is directly realized by physical connection, ensures the LCD display video letter after failure
Number normally receive.
The beneficial effects of the invention are as follows:
1st, distributed central control mode of the present invention, the LCD dynamic map master controls between each guest room are separate, arbitrarily
LCD dynamic map master control failures do not interfere with other guest rooms, and two LCD dynamic map master controls in same guest room are mutually only
Vertical, side master control failure does not interfere with opposite side and normally shown.
2nd, new dynamic map display system scheme can arrange control information according to train and trigger display respective routes letter automatically
Breath, rail, which exchange, multiplies information, and respective site enabling side instruction picture, left and right sides are triggered automatically according to information of arriving at a station, switch gate information
Dynamic map picture can be according to row information automatic mirror-image above and below train.
3rd, each one difference of LCD master controllers sends mouth and cascades multiple dynamic map screens, and each map screen has
Bypass functions, single display screen failure do not interfere with other display screens and normally shown.
4th, the LCD dynamic map master control quantity that present system needs is few, and its autgmentability is strong, and anti-interference is high, and cost is low.
