Definitions

  • Weaving machines and other machines generally have a central control that communicates with assemblies and / or devices that are required to operate the weaving machine.
  • Bus systems can be provided for communication between internal and external devices of the weaving machine as well as components and assemblies of the same and the weaving machine control, as has become known, for example, from DE 4238600 C2 for knitting machines.
  • a central processing unit interacts with motor control units via a bus in order to control them.
  • the motor control units are connected to the bus in parallel and are addressed via addresses.
  • CAN buses For data communication between a central control device and several subordinate participants e.g. Weft insertion devices, weft brakes, sensors and actuators are known as so-called CAN buses, which manage with three lines, namely CANH, CANL and ground.
  • CAN buses CAN stands for Control Area Network
  • the participants can receive data from the central control device, namely the weaving machine control, and return data to it. You can also communicate with each other.
  • each subscriber In order to make this possible, each subscriber must be assigned a separate address, which he recognizes as an identifier when he is to be addressed, and which he sends in order to correctly identify the sender of the transmitted data packet.
  • Looms have a large number of devices, assemblies and other elements that are connected to a CAN bus as participants. Such devices are, as mentioned above, the weft feed devices, the weft brakes, sensors or actuators. If a weaving machine is set up, the individual addresses of each participant (device) must be carefully documented so that no address is assigned twice. If changes are made, this is only possible based on the existing documentation. With a flexible configuration and changeability of the weaving machine, this represents a considerable difficulty with regard to the equipment for carrying out additional functions.
  • the control system or control method creates a possibility of integrating additional devices into the existing system without having to manually check or set them for address compatibility.
  • the devices are to be connected to the existing data bus and are automatically arranged in the system during an initialization procedure. This is achieved by individually and sequentially addressing devices that can be configured by the weaving machine control, that is to say devices with an initialization trigger line, so-called ITL devices. If they are addressed, they are assigned an individual address that is saved both on the device and on the weaving machine control.
  • the weaving machine control organizes the assignment of the addresses so that each configurable device (ITL device) receives a single address that is only assigned once and therefore only serves to address this one device.
  • additional addresses can be assigned several times (group addresses) in order to be able to address several devices with one shipment.
  • the configurable ITL devices are still without an address. You will therefore be addressed individually and in terms of hardware.
  • an additional line is used for this. If a CAN bus with the lines CANH and CANL and ground is used as the bus, at least one further line must be provided, the ITL line. This goes from the weaving machine control to everyone Devices that are arranged one behind the other in the additional line. Each device preferably has an input and an output. A switch is preferably provided between the input and the output and is open during the initialization of this device. The first signal coming from the weaving machine control can therefore only reach the device that is directly connected to the weaving machine control. It is activated and switched to initialization mode.
  • the switch After initialization, the switch is closed so that the next device in the chain receives the initialization signal and can start exchanging data with the weaving machine control. In this way, theoretically, an unlimited number of individual devices can be addressed one after the other and initialized individually.
  • the system is also open to permanently configured devices, e.g. for a dobby. These do not take part in the initialization, and the weaving machine control does not assign their addresses again.
  • the machine can be expanded at any time with additional devices and individual devices / assemblies can also be expanded or reduced without further notice; e.g. the number of weft feeders can be changed.
  • the weaving machine control checks its environment, i.e. it checks what devices are connected to the bus and assigns them to its address space.
  • the type and number of devices on the bus enable the weaving machine control system to automatically identify which functions are in operation or are operating less, which means that they can work properly after initialization. With this measure, the weaving machine control recognizes the number and functionality of existing system components, ie Actuators, sensors, devices etc. themselves. Accordingly, it also assigns addresses itself using this method.

Abstract

L'invention concerne un système de commande (1) permettant de commander des accessoires, des actionneurs, des capteurs et autres équipements d'une machine, notamment d'un métier à tisser. Les accessoires (3, 4, 5, 6) de ce système de commande (1) sont reliés à un dispositif de commande (2) par un bus CAN (7). En plus du bus CAN (7), au moins une autre ligne ITL-HIN permet de relier entre eux tous les accessoires (3, 4, 5) configurables par logiciel. La ligne ITL-HIN traverse tous les accessoires (3, 4, 5) en passant, dans chaque accessoire (3, 4, 5), par un commutateur (10) qui est ouvert avant l'initialisation. Par une fermeture successive des commutateurs, les accessoires (3, 4, 5) sont reliés les uns après les autres au signal ITL et ainsi activés les uns après les autres afin de se voir attribuer par le dispositif de commande (2) leur adresse individuelle qui leur sera utile lors du fonctionnement ultérieur.
