DCS System for PG-EXT

Naval Line

The Distributed Control System (DCS) is designed for the management of SPEICH windscreen wiper motors and window auxiliary devices. It consists of a microcontrollers network, integrated on board of each motor, in communication via CAN bus. For PG-EXT straight line wipers, DCS system have the following features:

  • two operating modes: in perfect synchronization, both in continuous and intermittent mode, and at  the maximum wiping speed for all the wipers;
  • the management of the wipers in groups that can have different working modes, each other independent;
  • wiring simplified due to a reduced number of wires and to the wiper control units connected one to the other like in a chain. The control unit is designed to have the possibility to remove the electronic board without interrupting the CAN bus communication;
  • great flexibility in varying the composition of the groups, modifying the park position side and adding items to the system (control panels, wipers and auxiliary devices) even after installation;
  • to drive auxiliary devices (electrovalves for water/air, remote switches for window and frame heaters) directly from the control unit.

Operation modes

CAN bus commands can be generated from a control panel, with a standard keypad from us proposed, from a gateway connected with switches installed by the customer on the consolle or directly from the integrated bridge system.

We propose two softouch panel types with standard graphic and customizable number of groups:

  1. DCS.ST panel: allows to operate up to 5 groups from 1 up to 8 wipers;
  2. DCS.ST.CS panel: allows to operate up to 12 groups from 1 up to 8 wipers.

In addition to the wipers it is possible to drive up to 4 auxiliary devices for each group, in particular:

  • the electrovalves for window washer equipment;
  • the compressed air electrovalves for purging water pipes;
  • the heated glasses remote switches;
  • the wipers anti-icing heater;

When the customer wants to compose the control panel with his own switches and lights, they can be connected to a gateway (code DCS.GW) able to communicate with the CAN bus network. With this device you can operate:

  • up to 5 groups from 1 up to 8 wipers ;
  • up to 4 auxiliary for each group;

The DCS control system can be interfaced with the integrated bridge system via a dedicated CAN bus port. In this case SPEICH company provides the protocol for the development of the necessary software. A general recommendation is to use also a backup standard panel for testing or emergency purposes.
