Problems solved by technology

[0010] The technical problem to be solved by the present invention is that the bus driver in the prior art cannot know whether he has obtained the priority signal when driving to the intersection, and the non-bus driver cannot know whether the signal light provides the priority signal for the bus without Change the lights according to the normal changing rules, so that neither bus drivers nor non-bus drivers can take corresponding measures according to the current signal light status, and are in a relatively passive state

Embodiment 1

[0055] This embodiment provides a bus signal priority control system with an information display board, including a vehicle-mounted device, a data processor, and an information display board;

[0056] The on-vehicle device includes a radio frequency signal sending unit: used to send radio frequency signals, and requests to pass through preferentially;

[0057] The data processor includes a radio frequency signal detection unit: it is arranged on the lane where the vehicle enters the intersection, and has serial number information associated with the release phase, and is used to receive the radio frequency signal sent by the radio frequency signal sending unit;

[0058] Instruction output unit: connected to the radio frequency signal detection unit, obtains the serial number information of the radio frequency signal detection unit that receives the radio frequency signal, determines the release phase, controls the intersection signal light, and provides priority signals for the...

Embodiment 2

[0082] The difference between this embodiment and embodiment 1 is that, as image 3 As shown, the priority signal prompt unit includes an image projection module, and the priority signal processing unit includes an image processing module, and the image processing module processes the priority signal into an image signal and projects it on the windshield of the bus through the image projection module .

[0083] In step c, the priority signal processing unit uses an image processing module to process the priority signal into an image signal and sends it to the priority signal prompting unit; in the step d, the priority signal prompting unit uses an image projection module to convert the The image signal processed by the visual image processing module is projected on the windshield to prompt the driver.

[0084] During specific implementation, the image projection module projects the priority signal on the windshield and at the same time the audio prompt module prompts the driver...

Abstract

The invention relates to a bus signal priority control system with an information display board, which comprises a vehicular device with radio-frequency signal transmitting modules and a data processing unit with a radio-frequency signal detecting module. The vehicular device further comprises priority signal prompting units, which are in one-to-one correspondence to the radio-frequency signal transmitting modules and have unique defined ID (identification) information. The system further comprises a priority signal processing unit which is used for acquiring the ID information of the priority signal prompting units and processing the priority signals to transmit the same to the corresponding priority signal prompting units. Signal transmission between the priority signal processing unit and the priority signal prompting units is realized through a wireless communication unit. The information display board is arranged at a crossing to prompt drivers in two directions of whether any buses acquire the priority signals or not and how signal lamps change next, the drivers in the two directions can respond instantly to decide whether to continue driving through the crossing or decelerating and parking to wait according to the prompting information on the information display board.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a bus signal priority control system and method with an information display board. Background technique [0002] Urban public transport is an important part of green transportation and low-carbon life. With the rapid development of social economy, urban population is becoming more and more dense, and the problem of urban road congestion is becoming more and more prominent, which has also become an important factor affecting people's living standards. In order to alleviate traffic congestion and meet people's travel needs, signal priority control is implemented on public transport vehicles, which has been widely used at home and abroad. [0003] Existing Chinese patent document CN 101458873A discloses a kind of real-time control method of bus priority signal based on RFID, RFID electronic chip is installed on the bus, and the second RFID reader and the first RFID reader ...
