Problems solved by technology

However, there is interference in the GPS systems of different tire cranes, and the GPS system signal of the tire cranes close to the bridge crane will also be interfered by the bridge crane
In addition, the data of the GPS positioning system is easy to be tampered with, the security is not high, and the positioning data needs to be constantly corrected

Embodiment Construction

[0023] Such as figure 1 As shown, steering switch (2), display (3), driving encoder (4), trolley encoder (5), spreader encoder (6), tire crane PLC (7), alarm (8), box Bit management system (9) is all connected with computer (1). The wharf electronic map is surveyed and drawn in advance and stored in the computer (1). The driving encoder (4) is on the driving motor to measure the traveling distance of the tire crane, the trolley encoder (5) measures the position of the trolley, the spreader encoder (6) measures the height of the spreader, and all position information is sent to the computer (1) for processing Conversion. The container location management system (9) provides the tire crane bay position information, and the tire crane PLC (7) provides the spreader signal and the spreader lock signal. When the tire crane turns, the steering switch (2) sends left or right turning information to the computer (1). Display (3) is installed in the driver's compartment, and displays...

Abstract

The invention provides a container tyre crane and hanger full-field positioning system using encoders. According to the invention, the system stores a pre-mapped electronic map of a wharf and the initial position of a tyre crane in a computer, then converts the pulse number of a travelling tyre crane encoder on the basis of the computer and a reduction ratio so as to acquire the locations of the tyre crane in the full field, and then acquires the position of a trolley and the height of a hanger through a trolley encoder and a hanger encoder so as to further position the crane in the full field; moreover, the system verifies and updates information about container models and tyre crane positions in real time according to hanger signals and hanger lock signals provided by a tyre crane PLC and stowage location provided by a container position management system.

Description

technical field [0001] The invention relates to a container tire crane, in particular to the positioning of the container tire crane and the spreader in the entire container yard. Background technique [0002] At present, most of the positioning of container tire cranes and spreaders in the yard on the port terminal is through the GPS system. However, there is interference in the GPS systems of different tire cranes, and the GPS system signal of the tire crane close to the bridge crane will also be interfered by the bridge crane. In addition, the data of the GPS positioning system is easy to be tampered with, the security is not high, and the positioning data needs to be constantly corrected. Contents of the invention [0003] In order to realize the positioning of container tire cranes and spreaders in the whole field, the present invention provides a whole field positioning system for container tire cranes and spreaders using encoders. Stored in the computer, and then ...
