Description
Technical field
The utility model belongs to the intelligent transportation control field.
Background technology
At present, intelligent traffic signal lamp control system and intelligent traffic administration system technical field are in order to administer traffic jam issue, proposed many solutions, transport information is induced gradually and is admitted by vehicle supervision department, and city road and crossing all start to adopt the induction information board to guide and shunt.One of them control mode is that crossing arranges and treats row district to increase vehicular traffic in the signal period, alleviation crossing communication pressure.Crossing arranges treats that the row district has two aspects to need to consider: 1) treat the setting in row district, traffic programme department completes; 2) treat row district's special-purpose guiding display screen, guiding driver scheme according to the rules enters and treats the row area.In the prior art situation, having product to be provided with guidance information can be with the variable area to be transferred display screen of signal lamp indicator signal.But this series products intelligence shown according to the particular schedule mode, in case crossing traffic signal dispatching mode changes, display screen can't work.
Domestic motor vehicles are increasing, and urban road also is faced with congested traffic problem day by day, and traffic congestion causes the delay of time, and vehicle supervision department introduces multiple technologies, adopt various measures to alleviate the urban road that day by day blocks up.Crossing is set treats that row district has been applied to many urban road crossing as a solution, for can not widening road or increase the crossing of number of lanes, the solution of a kind of relative efficiency of can yet be regarded as.The row district that treats that arranges according to crossing need to provide the demand of navigation information.
Summary of the invention
The utility model provides a kind of special use guiding display screen that can use various traffic signals scheduling modes, to meet the row district intersection information prompting demand that remains that arranges.The utility model device is reliable and stable, and the information faces switching in time, can be according to traffic signaling equipment instruction configuration display mode; The guiding clear display; According to precisely switching is set immediately, the display mode retouching operation is simple.The Installation and Debugging simple operation.
The utility model is achieved by the following technical solution: the special-purpose guiding of a kind of band communication interface display screen, its technical characteristics are that the control of communication module link information is controlled and is connected navigation information display module formation with output module with output module, information;
It is that model is that the STC12C2052AD chip is connected signals collecting optocoupler 817, output is controlled field effect transistor 9540 and formed that described information is controlled with output module;
Described communication module is that the 232 serial signal interface chips of MAX232 and 485 serial communication interface chips that model is 65HVD3082 form by model;
Described navigation information display module is the LED display module.
The utility model takes into full account safety and reliability, and communication and two kinds of mode of operations of self study are provided, and supports simultaneously to realize by communication interface setting and the query function of information display mode.This guiding display screen of turing has simple installation, controls the characteristics such as flexible.
Description of drawings:
Fig. 1 is the special-purpose guiding of a kind of band communication interface display screen schematic diagram;
Fig. 2 the utility model applied topology structural drawing;
Fig. 3 shows figure for guiding.
Embodiment:
As shown in Figure 1,1 is communication module, and MAX232 is 232 serial signal interface chips, and 65HVD3082 is 485 serial communication interface chips.2 control and output module for information, and central authorities process and adopt STC12C2052AD, signals collecting partly to adopt optocoupler 817, and output adopts field effect transistor 9540, the judgement of completion system signal, system call and information output control work.3 is the LED display module, and module adopts the mode of sketching the contours, and saves cost.
As shown in Figure 2, the utility model application is comprised of traffic signals main control system and special-purpose guiding display screen.8 special-purpose guiding display screens of the maximum support of native system.The utility model innovation that is applied to native system is to introduce serial communication mode control information display mode, makes the information display mode controlled; Add the dynamic vehicle figure to make information more humane in demonstration information; In demonstration information, " crossing is met block up and entered " is shown in red eye-catching, has more alarming effect.
As shown in Figure 1, Figure 3, the utility model relates to the special-purpose guiding of a kind of band communication interface display screen, and this device comprises communication module, information control and output module, navigation information display module and face shield and shell four parts.1) current module section comprises 232/485 communication pattern, adopts chip MAX232 and 65HVD3082; 2) information is controlled and output module, and central authorities process and adopt STC12C2052AD, signals collecting partly to adopt optocoupler 817, and output adopts field effect transistor 9540; 3) guiding display part, content comprises three parts: the information of 1. turning left: " the left-hand rotation car enters area to be transferred " (word)+dynamically arrow (the figure)+dynamic vehicle sign (figure) of turning left, sketch the contours with the green LED pipe; 2. the information of keeping straight on: " straightgoing vehicle enters and treats the row district " (word)+dynamically arrow (the figure)+dynamic vehicle sign (figure) of keeping straight on, sketch the contours with the green LED pipe; 3. information warning: " crossing is met block up and entered " (word), sketch the contours with the red LED pipe.4) face shield and shell, this part relate in particular to face shield and adopt polycarbonate, are different from frangible acrylic material.The STCK12C2052AD single-chip microcomputer, adopt 1 clock/machine cycle, enhancement mode 8051 kernels.
