Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0050] 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 :

[0051] a. The device is packaged in a metal box and connected to the water level sensor and solar power supply through a shielded cable.

[0052] 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 instructio...

Abstract

The invention discloses a method automatically generating dredged channels according to water-level variation. A water-level automatic remote control detecting device is installed at stream segment and sends detected water-level information to a management center computer, the management center computer receives and releases water-level data, a terminal computer receives the water-level data and analyzes and processes the data, and the dredged channels are generated automatically according to processed results. By applying the method automatically generating the dredged channels according to the water-level variation, a navigation department and a water conservancy department can conveniently perform long-distance real time monitoring to river levels, a management department can check water levels of river hey points and historical records of the water levels in real time in the office and analyze variation rule of the water levels according to the historical records of the water levels. Unattended water-level monitoring can be achieved, and the dredged channels suitable for current water levels are generated automatically according to the water levels and are used for guiding ships to sail safely.

Description

technical field [0001] The present invention relates to a river channel map, especially a method for automatically detecting, sending, and receiving river water levels and automatically generating navigation channels based on the received water level information. Background technique [0002] In recent years, the application of GPS navigation technology on inland ships has been developed to a certain extent, but many problems have also been encountered. One of the important problems is that the waterway of the inland river does not have clear boundaries like the highway, so there are serious hidden dangers in terms of traffic safety and efficiency. [0003] Now, there are also some manufacturers' electronic waterway charts that add virtual navigation channels, that is, draw two lines on both sides within a certain range in Hanoi to simulate navigation channels. This method must be drawn manually, and after the water surface elevation value changes, it needs to be redrawn ma...
