METHOD AND DEVICE FOR CONTROL AND PREPARATION OF SAND STOCK IN THE SAND BUNKER OF SAND-SPREADING DEVICES IN VEHICLES, IN PARTICULAR RAIL VEHICLES

摘要

1. A method of monitoring the supply of sand in the sand bunker of a sand-distributing device of a vehicle, in particular a rail vehicle, especially an express train or a fast train, and a pulse sensor is provided, for example, a selenium photocell, for monitoring the level of sand supply by which it is displayed in a control point, in particular in the area where the driver is located, for example on the instrument panel, characterized in that using a diagnostic system control the flow of sand supplied by sand do to the injector, and the report on the control point on the flow of sand flow past it. ! 2. The method according to claim 1, wherein the sand flow is sent to successive cells of the cell wheel, characterized in that the number of revolutions of the cell wheel is measured, after which, for example, using a table or computer, the volume of sand is also measured per unit time and displayed in the form of flow per unit time at a checkpoint, mainly in the area where the driver is located. ! 3. The method according to claim 1, characterized in that upon reaching a predetermined effective operating time, an appropriate signal is sent to the control system or to the driver’s cab for servicing the sand distributing device. ! 4. The method according to any one of claims 1 to 3, characterized in that the rotational speed of the cell wheel is controlled by a tacho signal, and the amount of sand is continuously adjusted depending on the speed of movement. ! 5. A device for implementing the method according to any one of claims 1 to 3, characterized in that the cell wheel drive is adjustable with a suitable electronic control unit
