Embodiment 1

[0099] The Beidou precise space-time bus networking communication monitoring terminal includes a Beidou positioning unit, a micro-communication unit, a vehicle-mounted computing unit, a signal transceiver unit, and a display module. The micro-communication unit, the Beidou positioning unit, the vehicle-mounted computing unit, The display modules are connected sequentially, the on-vehicle computing unit is connected to the signal transceiving unit, and the miniature communication unit is connected to the signal transceiving unit.

[0100] The miniature communication unit includes a Beidou / GNSS pilot antenna and a communication antenna for receiving Beidou / GNSS satellite signals and receiving and sending 3G / 4G or WiFi signals.

[0101] The Beidou positioning unit is used to receive the Beidou satellite signal received by the Beidou / GNSS pilot antenna, calculate the difference, and effectively correct the system error in satellite positioning, and combine the inertial navigation s...

Embodiment 2

[0128] As described in Embodiment 1, the working method of the Beidou precise space-time bus networking communication monitoring terminal includes:

[0129] (1) The communication monitoring terminal is installed on each bus, and numbered according to the route; taking the No. 1 bus as an example, the numbers are 1-1, 1-2, ..., 1-n ;

[0130] (2) Time distributed calibration: turn on the Beidou precise space-time bus network communication monitoring terminal, and perform unified time service to the traffic master control center, bus station control center and all buses;

[0131] (3) Beidou positioning: real-time positioning of all buses;

[0132] (4) Sub-meter-level positioning of all buses using ground-based augmentation methods;

[0133] (5) data communication: the positioning information of all buses that will be obtained is sent to traffic total control center, bus stop platform control center respectively by described signal transceiver unit; Calculate the distance betwe...

Embodiment 3

[0137] The working method of the Beidou precise space-time bus networking communication monitoring terminal as described in Embodiment 2, the difference is that the specific positioning method of the step (4) is: use the Beidou differential positioning and inertial navigation combined positioning system to perform all the buses sub-meter positioning,

[0138] The Beidou differential positioning and inertial navigation integrated positioning system adopts the pipeline error propagation model to establish the Kalman filter model system equation, the coordinate system adopts the geographic coordinate system, and the earth is regarded as a spheroid, and the Kalman filter linear model is as follows:

[0139]

[0140] In formula (I): They are state vectors respectively, which are longitude error, latitude error, altitude error, east speed error, north speed error, sky speed error, inertial navigation platform's east, north, sky attitude error angle, Beidou Receiver clock and fr...

Abstract

A Beidou accurate time-space bus networking communication monitoring terminal comprises a Beidou positioning unit, a miniature communication unit, an on-bus computing unit, a signal transceiver unit and a displaying module. The miniature communication unit, the Beidou positioning unit, the on-bus computing unit and the displaying module are successively connected. The on-bus computing unit is connected with the signal transceiver unit. The miniature communication unit is connected with the signal transceiver unit. The Beidou accurate time-space bus networking communication monitoring terminal realizes real-time accurate positioning of the bus in driving and communication between the bus and an upper control center, thereby more accurately estimating arrival time of the bus, so that the passenger can be liberated from waiting without information. Bus scheduling is optimized so that buses are reasonably and uniformly distributed in a line. Communication between the bus, a signal machine control center and a traffic administration bureau master control center is realized. A bus preferable communication strategy is reasonably arranged.

Description

technical field [0001] The invention relates to a Beidou precision space-time bus networking communication monitoring terminal and a working method thereof, belonging to the technical field of intelligent transportation. Background technique [0002] Due to the continuous and rapid development of my country's economy and society, especially the continuous improvement of urbanization and motorization, urban traffic problems have become increasingly serious. Vigorously developing urban public transport has become a major livelihood issue related to the vital interests of the people, which has aroused the attention of governments at all levels. attention and attention. However, looking at the current situation of public transportation in my country, under the circumstance that all kinds of social motor vehicles, bicycles and buses compete for the right to use roads, public transportation vehicles are not running smoothly, causing serious delays. Disadvantages such as poor servic...
