Control system for a jacquard mechanism, jacquard mechanism and weaving machine equipped with such a system

An electronic board for a control system for at least one Jacquard mechanism for forming shed, the least one Jacquard mechanism having electromechanical selection devices including electromagnets, the electronic board comprising

• an at least one intermediate controller,
• all electromagnet control units of the control system that are connected to the at least one intermediate controller, and
• connecting tracks between the at least one intermediate controller and the electromagnet control units, and
• wherein the control system comprises
• a primary controller intended to communicate with a weaving machine equipped with the Jacquard mechanism and including at least one memory to store weave pattern data and at least one computer able to generate the publication and modification of this pattern data,
• at least two secondary controllers, each electrically connected to the primary controller and each able to control a group of electromechanical selection devices, each secondary controller having at least one memory for storing weave pattern data and at least one computer,
• the electromagnet control units, each associated with at least one electromechanical selection device, each control unit being electrically connected to a secondary controller and having a shift register for receiving activation states of the electromagnets that it controls, and
• the at least one intermediate controller in direct electrical connection with one of the secondary controllers and with at least two electromagnet control units.
