Embodiment Construction

[0016] According to FIG. 1 , the valve unit consists of a plurality of electro-pneumatic valves ( 1 ) connected together, the fluid and electrical connections of which are produced by means of individually assigned base elements ( 2 ). The individual base elements ( 2 ) are likewise connected together and have a common channel guide (not shown) for the fluid supply.

[0017] Each valve (1) contains an electronic transceiver in which the identification of the valve in the form of a serial number, the identification of the function of the valve, the date of manufacture and the identification of the batch number are stored.

[0018] The reading means assigned to each transceiver (3) on the side of the base element (2) comprises a plurality of individual RFID read heads (4), via parallel lines with individual signal transmission lines (5), each The read head leads to the entrance of a multiplexer unit (6). In order to read the individually assigned information content of each tra...

Abstract

The invention discloses a valve unit with a plurality of valves linked together for switching a pressurized air flow, where electronic means of valve detection consisting of individual valve-side transponders and a reading device are provided, where the reading device consists of individual RFID read heads, each allocated to a transponder, as well as an RFID reading unit common to all RFID read heads, and where the RFID read heads are connected with the RFID reading unit via a multiplexer unit.

Description

technical field [0001] The invention relates to a valve unit for switching compressed air flows with a plurality of valves connected together, wherein each valve is assigned to at least one basic element of the system for fluid and / or electronic applications and is provided with a separate Valve detection electronics consisting of transponders on the valve side and reading devices on the base element side. Background technique [0002] The scope of application of the pneumatic valve unit mainly extends to the pneumatic automatic control system, with which the machining process is carried out. In one valve unit, there are several valves for controlling pneumatic components (such as air cylinders) that are combined together at a local location and can thus be supplied with compressed air and electronic control signals in a central supply . The valve unit can also have a plurality of valves whose basic elements are integrated directly into the housing, wherein the channel sec...
