All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The station reporting monitoring system is a high-precision, all-weather and global radio positioning and monitoring system, and provides three-dimensional position, speed and time information for users in real time. Currently, station reporting monitoring has wide and successful application in many fields.
The station reporting module has strong functions, and particularly, the differential GPS can provide higher-precision positioning.
The navigation information can be further combined with a microcomputer, and the data of the station reporting module is processed more complexly by utilizing the superiority of system programming, so that the greater potential of the station reporting monitoring system is exerted.
The station reporting module is used for uploading the moving carrier in real time, and the precision and the real-time performance of the data of the receiver are one of key factors influencing the station reporting resolving precision. The key point of the present invention is how to perform dynamic real-time ranging, how to synchronize, extract data in real time, and ensure the accuracy and stability of evidence.
Referring to fig. 1, the present invention provides a technical solution: an interval automatic alarm method based on station reporting data comprises the following steps:
the method is based on the hardware of a station reporting module, adopts the GPS84 coordinate, judges the station reporting time by using GPS data, and acquires real-time station reporting data which comprises time, station, longitude, latitude, speed, direction and driver and passenger information. And pushing the data into the functional service, calculating the data through the service, and performing sectional type detection and assessment on the vehicle running condition according to the set interval range and the assessment standard.
The scheme mainly comprises 2 parts: user equipment, functional services.
1. The user reception apparatus section:
the station reporting data is the basis for positioning by the system, and the purpose of applying station reporting positioning can be realized only by the receiver.
The tasks of the station signal receiver are as follows: the method can capture signals of satellites to be detected selected according to a certain satellite height cut-off angle, track the operation of the satellites, convert, amplify and process the received GPS signals so as to measure the propagation time of the GPS signals from the satellites to a receiver antenna, interpret navigation messages sent by the GPS satellites and calculate the three-dimensional position, the three-dimensional speed and the time of an observation point in real time. The structure of the station reporting receiver is divided into an antenna unit and a receiving unit.
2. And a function service part:
after the vehicle-mounted station reporting module captures and tracks satellite signals, the pseudo distance and the distance change rate from the receiving antenna to the satellite can be measured, and data such as satellite orbit parameters can be demodulated. According to the data, the microprocessor computer in the receiver can perform positioning calculation according to a positioning calculation method, calculate the information of the geographical longitude and latitude, the height, the speed, the time, the station and the like of the user, and then transmit the information into the server, so that the service can calculate whether the vehicle reaches the preset operation standard according to the information.
Wherein, the coordinate system adopted by the GPS is a WGS-84 coordinate system.
The WGS-84 coordinate system is the coordinate system adopted by the current GPS, and ephemeris released by the GPS
The parameters are based on this coordinate system. The WGS-84 coordinate system is known collectively as the World geodetic System-84 (World geodetic coordinate system, 84). The WGS-84 coordinate system is established by the United states department of defense mapping in 1987 and replaces the WGS-72 coordinate system adopted by the GPS at the time
The system becomes the coordinate system used for the GPS. The origin of coordinates of the WGS-84 coordinate system is located in the center of mass of the earth, the Z axis is parallel to the polar axis direction of the protocol earth defined by the time element BIH1984.0, the X axis points to the intersection point of the meridian plane and the equator of the earth defined by the time element BIH1984.0, and the Y axis, the X axis and the Z axis form a right-handed system. As shown in fig. 2 below, the earth is a sphere with a complex surface, and people derive an approximate ellipsoid by taking a "terrestrial body" formed by an imaginary average stationary sea surface as a reference, and theory and practice prove that the ellipsoid approximates an ellipsoid rotating around an ellipse with the short axis of the earth as an axis, and the ellipsoid can be expressed by a mathematical formula, and points on the natural surface are integrated on the ellipsoid, so that the ellipsoid can be calculated.
The station reporting module comprises a data processing module, the data processing module receives data from a serial port and places the data in a cache, the cache is a long string of byte streams before further processing, and the information cannot be utilized before classification and extraction. Therefore, the information of each field must be extracted from the buffered byte stream by a program and converted into the actual useful positioning information data. Similar to other communication protocols, the information extraction of the station data must first specify the frame structure, and then the extraction of each positioning information can be completed according to the frame structure. As used herein, a receiver whose data sent to a computer consists primarily of header, trailer, and intraframe data, primarily "$", "#", etc. The frame head marks the composition structure of the data in the subsequent frames, and each frame takes the carriage return symbol and the line feed symbol as the frame tail to mark the end of one frame.
The application scenario of the invention is as follows:
scene one: the public transportation enterprise needs to know whether the current vehicle is carried out according to the plan
Through the functional design of this scheme, through acquireing the real-time data of reporting a stop of current vehicle, whether the current vehicle reachs this station on time of calculating, perhaps still need several stations to arrive this station, the operation condition of current vehicle is demonstrated through the result is audio-visual to in time adjust the running state of vehicle.
Scene two: the public transport enterprise has special lines and adopts different section examination modes
In cities, lines with complex road conditions usually exist, the situation difference between different places is large, assessment cannot be performed according to the same standard, the assessment needs to be distinguished and treated, and the assessment can be flexibly performed in a segmented manner according to different interval standards.
Scene three: constantly reminding drivers of the standard gap with the expected operation
In daily operation, especially in morning and evening peak periods, a plurality of uncontrollable factors can occur to cause delay, congestion and the like, a follow-up driver can not accurately grasp the difference from a predicted standard, and the scheme can accurately prompt the current condition of the driver in real time so that the driver can adjust in time.
The invention utilizes the real-time stop reporting monitoring and checking technology to realize that the bus real-time inter-partition checking system does not need to additionally expand the bus hardware, plays a great role in controlling cost and improving the cost performance of products, and can be integrated into a future Intelligent Transportation System (ITS) to ensure that the system is intelligent. With the acceleration of the informatization process, the GPS must play an increasingly important role in modern traffic engineering.
