Definitions

  • the invention relates to a correction control for an irrigation system consisting of pipelines which are carried by tower towers and are coupled to one another and are moved at right angles to the pipe axis. The movement can also take place in such a way that a point of the pipeline is held and this moves in a circle around this point.
  • Such systems are known under the name CENTER PIVOT or LINEAR - MO VE SYSTEME. As a rule, they are driven by electric motors that are mounted on the individual towers. The straight alignment of these systems is achieved by switching the individual motors on and off.
  • each tower which is connected via a supply cable to the central control cabinet (control center), which is usually located at the pivot point of the system.
  • the main circuit for the drive motors and the control voltage for the control units are transmitted via this cable.
  • the main parts of the control center are a transformer for the control voltage, a main switch that provides the electrical supply to the system, a switch for the forward and backward movement of the system, a percentage timer for the speed control of the last tower and a switch that sets the system in motion or stops. Because the speed of each drive motor is fixed, each tower would run at the same speed when the system was started. With CENTER PIVOT systems, however, the tower located further inward must travel a proportionally shorter distance in order to make a 360 ° turn.
  • the tower located further inside must run for a proportionally shorter period of time in order to keep the system straight.
  • the Percent timer built in which fixes the speed of the system. If this is set to 100%, the contactor of the last tower operator motor closes, which means that 400 volts are continuously supplied to the engine and the tower runs continuously. For irrigation reasons, it is necessary to run the system at lower speeds, with the percentage timer being set to 50%, for example, which means that the end tower 1 is in operation for 30 seconds within a minute and stands still for 30 seconds.
  • This tower is also known as the control tower. No scanning device is arranged on this, since no deflection of a subsequent tower has to be registered here. There is a scanning device in the inner towers, which transmits the degree of angulation between two towers via a transmission part and a switch cam to two microswitches, one switch serving as a work switch and the other as a safety switch.
  • the transmission part on the penultimate tower is moved forward with the control cam; at a certain angle, the switch cam actuates the microswitch, whereupon the contactor closes and the drive motor sets the tower in motion. This runs until it is in a straight line with the last tower.
  • This type of correction control has the disadvantage that not all towers can be controlled centrally from one point, that all tower motors can run simultaneously, and not the cause in the event of a buckling run and the exact position of the Error can be recognized, and the realignment must take place "manually" after a buckling run.
  • US Pat. No. 4,569,481 A speaks of a suitable alignment system of the type that is usually provided for center pivot irrigation machines. Control units that sit on the individual tower towers and a central control unit that is connected to the individual tower towers or their control units are not further disclosed in the latter document.
  • US 5 246 164 A and WO 00/15987 AI describe an irrigation system for the targeted irrigation or fertilization of a field with different areas, for example different soil conditions.
  • Such an irrigation system comprises sensors for the detection of moist or dry spots, the type and size of the vegetation, or the soil composition.
  • the valves of the individual sprinklers are controlled by a common control unit in accordance with the evaluation of the resulting data.
  • US 5 246 164 A gives more information on the straight alignment of the main arm.
  • the outermost tower is the control tower, which is crucial for the movement of the other towers.
  • Electromechanical devices monitor the relative alignment between the towers and set the motor of the respective tower in motion to ensure straight alignment.
  • a central one A control unit which centrally monitors the alignment of the individual towers and controls the motors centrally, is not disclosed.
  • the invention relates to a correction control for movable pivot irrigation systems, consisting of pipelines coupled to one another by towers 3, 4, 5, 6, these towers being aligned with one another via a control unit 7 mounted centrally on the tower.
  • Fig. 6 shows a tower with a control unit 7 and a scanning device 8 for determining the relative position to the neighboring towers.
  • the scanning device 8 consists of a transmission part and a switching cam 9 connected to it.
  • FIG. 7 shows the control unit 7 on an enlarged scale from different sides.
  • the control unit comprises a switching cam 9 connected to the scanning device 8, by means of which microswitches 12, 13 which can be actuated, the switch 12 serving as a work switch and the switch 13 as a safety switch, and a contactor 11.
  • each CAN node can be controlled centrally, this opens up new possibilities for controlling a CENTER PIVOTS, determining the maximum number of moving towers and setting the moving towers that are in operation at the same time.

Abstract

L'invention concerne une commande d'un système d'arrosage comprenant des conduites tubulaires accouplées entre elles et porteuses de tourelles mobiles. A chacune de ces tourelles sont associés un moteur d'entraînement et une unité de commande électrique, ainsi qu'un dispositif palpeur pour l'établissement de la position relative par rapport aux tourelles voisines, en liaison coopérante avec ladite unité de commande. L'invention est caractérisée en ce que le système d'arrosage comprend une unité de réglage centrale (2) communiquant avec les unités de commande (7) associées aux tourelles (3, 4, 5, 6), et en ce que ces unités de commande émettent des messages, en particulier des données sur les positions relatives desdites tourelles (3, 4, 5, 6), à l'unité de réglage centrale (2), éventuellement reçoivent des ordres de ladite unité de réglage centrale (2) et exécutent ces derniers.
