The utility model content
The purpose of this utility model is for overcoming defective and the deficiency that prior art exists, disclose a kind of contact that is suitable for large microwave equipment few, connect up less, efficient height, reliability height, cost is low and be easy to " fieldbus " and the modular control apparatus of installation and maintenance.This Design of device thinking is to be starting point with the control linkage to microwave generator in the microwave equipment, quote advanced " fieldbus " control technology (FCS) and in conjunction with integrated building block technique, with the field apparatus that possesses digital computation and digital communication ability as network node, with " fieldbus " as the tie of realizing digital communication between node, constitutes the Control Network of digital, transmitted in both directions, full dispersion, multiple-branching construction.The technical solution adopted in the utility model is: a kind of control device of microwave equipment, comprise the I/O module and functional module and the connected sensor that are connected with master controller, transmitter, driver, executive component, switching device, it is characterized in that master controller connects sensor by fieldbus, transmitter, driver, executive component, switching device, wherein, fieldbus connects sensor respectively by some accommodation function modules, transmitter, driver, executive component, switching device is provided with communications adapter between master controller and the fieldbus; Accommodation function module is parallel to the fieldbus that is provided with a plurality of interfaces; Microwave heating unit of each accommodation function module control linkage, a microwave heating unit is meant a fuel tank assembly or an air-cooled heating chamber; A fuel tank assembly contains 3～6 transformers and 3～6 magnetrons corresponding with it, and air-cooled heating chamber contains 3～6 transformers and corresponding with it 3～6 magnetrons and air-cooler.
Press fieldbus and modular control apparatus that such scheme is implemented, owing to adopted advanced " FCS " technology and distributed I/O module, system element and external control wiring have been reduced significantly, simplify the design of equipment and control device and reduced the workload and the error rate of the manufacturing, Installation and Debugging, also therefore reduced production, debugging and the maintenance cost of equipment.The utility model is with " FCS " system and organic combination of distributing I/O building block technique, not only for be extensive use of standardized " fieldbus " provide one general and make this system operate in the platform of the Industrial PC+WINDOWS/NT of standard, and provide favourable technical support for the development of microwave equipment to maximization, universalization and standardization aspect.The utlity model has certain technical advance and vast market prospect.
