Embodiment Construction

[0041] Further illustrate the present invention below in conjunction with accompanying drawing and specific embodiment:

[0042] 1. Reference figure 1, a water level automatic remote control detection device is composed of 1. embedded control center, 2. working DC power supply, 3.GPRS module, 4.GPS module, 5. water level pressure sensor, 6. remote management center computer, and its working steps are as follows :

[0043] a. The device is packaged in a metal box and connected to the water level sensor and solar power supply through a shielded cable.

[0044] b. The embedded control center is connected to the working power supply module. After the power supply, the embedded control center starts to work, circularly detects the changes of various module parameters, calculates and analyzes the detection results and sends the information to the remote management center computer, and at the same time receives the remote management center computer. Control instructions and execut...

Abstract

The invention discloses a method for automatically updating a navigation channel chart according to water level change. The method comprises the following steps: mounting a water level automatic remote control detection device on a river reach; transmitting the detected water level information to a management center computer by the water level automatic remote control detection device; receiving and issuing water level data by the management center computer; receiving the water level data and analyzing and processing the water level data by a terminal computer; and automatically modifying water deep point data value in an electronic navigation channel chart and the color of a relevant chart layer according to the processing result by a terminal computer. According to the method disclosed by the invention, remote real-time monitoring of a shipping department and a water conservancy department for the water level of rivers can be facilitated; the water level of key points of the rivers can be looked up at an office by a management department; and the electronic navigation channel chart suitable for the current water level can be automatically updated according to the change of the water level and further the safety navigation of the ship is guided.

Description

technical field [0001] The invention relates to a river waterway map, in particular to a method for automatically detecting, sending and receiving river water levels and automatically updating an electronic waterway map according to the received water level information. Background technique [0002] In recent years, GPS navigation technology has become more and more widely used in automobiles, more and more vehicles are installed, and the accuracy of navigation is also getting higher and higher. However, the application of this technology on inland ships has been greatly limited. The main reason is that the water level of the inland river varies greatly with the seasons, and the water depth varies greatly between the wet season and the dry season, especially in the reservoir area and upstream rivers. The drivable surface of the road is constant, but the drivable surface of the river changes with the change of the water level. Therefore, if the navigation map of the ship-bo...
