Problems solved by technology

Third, the microwave output power can be continuously adjusted at present, but the industrial production line still stays at manual adjustment of the microwave output power
However, in most microwave heating and drying occasions, the microwave power does not change correspondingly with the change of load temperature.

Abstract

A distributed type microwave heating and drying control device comprises a temperature sensor used for measuring the temperature of materials and further comprises a microwave power meter, a CAN bus, a PID controller based on a neural network and a microwave executing unit based on the neural network, wherein the microwave power meter is used for measuring the microwave refection power, and the CAN bus is used for transmitting temperature data, microwave refection power data and the numerical value of the microwave output power. Temperature signals collected by the temperature sensor and reflection power signals collected by the microwave power meter are sent to the CAN bus, the PID controller based on the neural network obtains the corresponding temperature and the corresponding reflection power from the CAN bus and takes the corresponding temperature and the corresponding reflection power as input of the PID controller, the numerical value, processed through an algorithm, of the microwave output power is sent to the corresponding microwave output executing unit, and the microwave output executing unit receives the numerical value of the microwave output power and outputs microwaves with the corresponding power. According to the device, the output power is adjusted in real time according to changes of the temperature of a load, and therefore the heating process or the drying process is made to be safe, efficient and rapid, and the aim of saving energy is achieved.

Description

technical field [0001] The invention relates to a distributed real-time microwave heating and drying control device and method. Background technique [0002] There are many applications of microwave heating or drying. At present, there are several methods for power control. First, when heating similar to a household microwave oven, different power levels can be selected, and the constant power can be output at regular intervals. Second, the microwave power is controlled by increasing or decreasing the number of magnetrons through switching devices such as relays. Third, the microwave output power can be continuously adjusted at present, but the industrial production line still stops at manual adjustment of the microwave output power. Compared with traditional methods, microwave heating and drying have the characteristics of fast speed and high efficiency, but if the power is not properly controlled, it will cause energy waste and even cause safety accidents. During the hea...
