Abstract
A system for managing an open storage area by means of a global position system (GPS) comprises a server (2), a GPS base station (1) installed at a fixed position of the open storage area, a group of GPS devices (3) and a loading and unloading control operation terminal (5) electrically connected with the GPS base station (1) and the group of GPS devices (3). When a loading and unloading machine places an object in a certain storage region of the open storage area, the GPS devices (3) fixed on the loading and unloading machine acquire longitude and latitude values of the position where the GPS devices (3) are located, correct acquired values according to position error corrected values sent by the GPS base station (1) through the same group of satellites and send the acquired values to the loading and unloading control operation terminal (5) electrically connected with the GPS devices (3). The loading and unloading control operation terminal (5) confirms the numbers of the region, line, row and layer of a position where the object is placed and sends the data to the server (2). The system for managing the open storage area by means of the GPS has the advantages that a real-time kinematic (RTK) technology is applied to the open storage area to accurately position the object, the problem of poor positioning accuracy of a single GPS device is solved, the position where the object is placed can be accurately and quickly recorded, field operation is simplified and facilitated, and the efficiency and the accuracy of the existing operation can be improved.
Description
Technical fieldThe present invention relates to stacking or the de-stacking of object, relate in particular to by GPS and effectively manage the open storage ground method and system.
Background technologyGoods for open storage ground is stacked management, and prior art generally all is to adopt the position that the manual record goods is stacked, and is example with the Container Yard: well-known, container refers to have certain intensity, rigidity and specification and specializes in the large-scale loading container that turnover is used.Each container has unique number, is made up of 11 codings, and preceding 4 is letter, and back 7 is numeral; The profile of container is rectangular parallelepiped, and common Container Dimensions has: 20 feet, 40 feet, 45 feet.International standard is a TEU unit by 20 1 chis.Container is pressed the international standard manufacturing, the data of every kind of box size, for example:
20 forty equivalent unit 40s are called for short 20GP, and physical dimension is: 6.1M * 2.44M * 2.59M
40 forty equivalent unit 40s are called for short 40GP, and physical dimension is 12.2M * 2.44M * 2.59M
Container Yard is the place of depositing container, for ease of management and to reasons such as operating area, environment layout requirements, the stockyard can be divided into a plurality of districts, general 2 bit digital that adopt identify, container is stacked by row, column, floor again in each district, therefore, determine in the stockyard its position of certain container by: district, row, column, floor are described.For example certain stockyard, container place recorded information is " 01130807 ", shows that namely this container lot is in 01 district, 13 row, 08 row, 07 floor.
All containers on Container Yard all need to know its position, but a Container Yard is often stacked up to ten thousand containers simultaneously, in appearance except size, color, Company Logo's difference, can not be from distinguishing some concrete containers in appearance.Therefore container is deposited on the stockyard, the case number (CN) of necessary accurate recording container and the spatial field position in its stockyard, place coding as position, the field misregistration of container, will bring the work of looking for case and overturning in the stockyard, waste a large amount of time, and manpower, device resource.
Classic method is the position input system again that manual paper records each container, but along with the operating efficiency of Container Yard improves, require the space availability ratio in stockyard to improve, bigger Container Yard site work has all adopted portable terminal now, replace manual paper record as handheld terminal computer, car-mounted terminal computer, come case number (CN) and a position information of record set vanning by computer systems and networks, but prior art is still by manual input mode information typing management system, not only input speed is slow, and the meeting input error, reduce work efficiency.
Prior art GPS (GPS) and RTK(Real-time kinematic, also be the dynamic real-time difference) technology, utilize two or one group of identical satellite of many GPS receivers simultaneous observation, can eliminate satellite orbital error, receiver clock error and ionosphere and tropospheric refraction error etc.Adopt the RTK technology can make bearing accuracy reach the centimetre-sized precision, thereby satisfy the needs of container actual location.
RTK technology maturation is applied in measurement, survey field, and its principle of work is: be installed in and just can carry out three-dimensional localization after GPS receiver on the base station is observed 4 satellites simultaneously, calculate the accurate coordinate of base station.Owing to exist orbit error, clocking error, atmospheric effect, multipath effect and other errors, the coordinate that calculates and the known coordinate of base station are different, there is error, base station utilizes the data chain that resultant positioning error modified value number is sent, received by subscriber station, and the subscriber station coordinate that it resolves is revised.Obtain revised user coordinates at last, cancellation the common error of base station and subscriber station, for example satellite orbital error, atmospheric effect etc. have improved bearing accuracy, precision can reach decimeter grade or higher, and this technology maturation is applied to measurement, survey field.
Summary of the inventionThe technical problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind ofly to manage the method and system of open-air goods yard by GPS, solves prior art and has the not high and problem such as make mistakes easily of manual typing, efficient.
