Problems solved by technology

[0006] However, for many small canals and open water networks, especially in developing countries, the technical equipment required to install motion automation is prohibitively expensive
For larger canals, the technical equipment required for the installation may be well worth the investment, but maintaining the installation is almost impossible due to the very open nature of such systems, which are fragile and exposed to a variety of different elements , such as wear, storm events, lightning, oxidation, vandalism, etc.

Embodiment Construction

[0049] figure 1 A schematic overview of a canal control system according to the invention and a method of using it at measurement points at or around a local structure (reference point of the canal system) when a trusted individual can act as the local operator. refer to figure 1 , indicating figure 1 Portions of Canal System 2 are depicted. A route 3 through the canal system to be followed by a local operator shows the layout of several measurement points at or around a local structure 4 of the canal system, such as adjustable gates or pumps. Each local structure 4 is marked by an identifier 5 such as a pie chart or a QR code. A marker is used as a reference for determining the absolute position of any local point in space. For example, the absolute position and orientation in space of any fixed part of a local structure may be used as a reference for determining water levels or settings of adjustable actuators included at that particular local structure.

Abstract

The invention relates to a canal control system for controlling the water level or water flow in a canal system (2), comprising: (a) a centralized master controller (20), (b) a local slave controller (30), (c) a wireless communication system between the centralized master controller and the local slave controller, (d) a (fixed) reference point (8) or (movable) marker (11) relating to the water level in the canal system, and (e) an adjustable actuator (9) in the canal system, such as agate or pump, whereby the local slave controller comprises a mobile device (13) capable of displaying a human- readable instruction which an operator can act upon to set the adjustable actuator. The operator takes a picture of the water level and / or of the setting of the adjustable actuator. The data of the picture is used for updating a mathematical model of predictive control of the canal system and for calculating the setting of the present actuator and for determining which actuator is to be visited next by the operator.

Description

technical field [0001] The present invention relates to canal control systems. In particular the invention relates to a canal control system comprising a centralized master controller and local slave controllers. Background technique [0002] The term canal system used in this article should be interpreted broadly. The canal system may be an irrigation canal system, a drainage canal system, or a river with adjustable control structures such as sluices in its course. [0003] Canals and open water networks around the world are used to transport water. For irrigation, water needs to be transported from its source to the user, while for drainage, large volumes of (rain) water need to be drained from the area. To manage the flow of water, structures such as downflush gates, overflush gates and pumps were built in the canal. By adjusting the configuration of these structures, flow can be directed through the canal, to side canals, and into and out of the reservoir. Changing ...
