Distant visual computer water level and flow monitor for pre-alarm and disaster prevention

Abstract

The present invention is a computer monitoring device for precaution against natural calamity using the remote visual signals of the water-level and the flow rate. The device comprises a visual signal capturing device used to capture the images of the water-level and the fixed reference at the site, compress and transform the images into the computer digital signals to output and transmit the image signals to a image processing computer through the network transmitting means such as the internet or the internal network; addition to the receipt of the computer image digital signals generated by the visual signal capturing device and the transmission of the signals to a monitoring screen for producing an instant image, the image processing computer performs the computation of the image data in a specific range on the monitoring screen using the dedicated program of the image deduction rule to calculate automatically the water-level, the flow rate and the distance between the water-level and the fixed reference, and displays the calculating result for reference by the monitoring people; if the water-level or the flow rate exceeds a preset warning value, an instant alarm will be produced, or the relevant equipments will be controlled.

Description

technical field [0001] The present invention relates to a remote video monitoring device for water level and flow disaster prevention and early warning computer, in particular to a device that captures actual water body images through video equipment to automatically judge changes in water level and flow at the far end with a computer, and can automatically Issue control signals and warning messages. Background technique [0002] For human daily life, water is one of the indispensable elements. In most areas of our country, it is not easy to store drinking water. Therefore, it is necessary to build reservoirs or dams to store water in order to provide daily livelihood and agriculture. Irrigation is required, but in the face of variable climate, over-development of slope land, poor soil and water conservation measures and other factors, whenever the rainfall increases sharply, the water level and flow of the reservoir or river will change rapidly. Without good monitoring, un...

AI Technical Summary

Problems solved by technology

[0004] 1. The measurement of water level and flow rate can only be obtained by personnel arriving at the site, and the general measurement locations are mostly remote, and it takes a long time for traffic to and fro. There are differences that affect the accuracy of the measurement

[0005] 2. Poor sightlines for nighttime surveys, and monitoring personnel are prone to danger

[0006] 3. The quality of monitoring personnel is not uniform, resulting in a lack of consistency in monitoring results

[0007] 4. The use of benchmarks and portable measuring instruments will cause errors due to human factors and the influence of the measurement environment, and it is not convenient to carry

[0008] 5. In the event of severe weather conditions or irresistible disasters, it is impossible to go to the site for survey and measurement

[0009] 6. In the case of floating objects in the water, moss, sediment, and damage to the covering pipeline will be attached to the measuring instrument, which will affect the accuracy of interpretation.

[0010] In view of the unsatisfactory aspects of the above-mentioned known methods of measuring water level and flow, the creators actively researched and developed, and finally produced the "remote video water level and flow disaster prevention and early warning computer monitoring device" of the present invention.
