In the embodiment of the invention, the multi-path adjusting group is arranged, so that the multi-path adjusting group can heat the microwave equipment together, thereby improving the working efficiency of the microwave equipment and enhancing the flexibility of the adjustment of the microwave equipment.
In the embodiment of the present invention, the microwave monitor 300 may be obtained in various manners, and in one possible implementation manner, the microwave monitor 300 may be an existing device purchased as needed, and at this time, the functions of controlling the microwave generator 100 and the microwave regulator 200 in the embodiment of the present invention may be implemented by using some functional components in the microwave monitor 300; in yet another possible implementation, the microwave monitor 300 may be a minimum micro-control system that is set according to the operational needs to ensure the micro-control unit operates. For example, in an example, the microwave monitor 300 may be a micro-control system designed based on an AVR XMEGA chip of ATMEL corporation, where the inside of the micro-control system may include processors ATXMEGA128A1U, 8K static random access memory, 8K (boot) +128K (app), 2K internal FLASH eeprom, 12-way analog-to-digital converter, 4-way digital-to-analog converter, 32-way pulse width modulation, 78 general input/output interfaces, 8 sets of serial ports, and the like, and the outside of the microwave monitor 300 may include an RS-485 communication interface, an RS-232 debug serial port, 4-way on-chip digital-to-analog converter, 7-way on-chip pulse width modulation, 10-way analog-to-digital converter, a plurality of general input/output interfaces, and the like.
Therefore, in the embodiment of the invention, the minimum micro control system which ensures the work of the micro control unit is adopted as the microwave monitor, so that on one hand, the microwave monitor can be ensured to normally complete the monitoring task, on the other hand, the structural arrangement of the microwave monitor can be simplified, each functional component in the microwave monitor can play a larger role, and the development cost of equipment can be saved.
Further, the collecting module 310 may be configured to detect microwave output signals output by each adjusting group, and for the microwave output signals output by each adjusting group, the processing module 320 may determine control signals of each adjusting group. Thus, the microwave adjuster 200 may adjust the phase adjusting modules in each adjusting group according to the control signal, so that the phases of the microwave output signals output by each adjusting group are different from each other, and meanwhile, the microwave adjuster 200 may adjust the power amplifier adjusting modules 220 in each adjusting group according to the control signal, so that the powers of the microwave output signals output by each adjusting group are different from each other.
In a specific implementation, the control signal may be determined by the processing module 320 according to characteristics of the microwave output signal, where the determination manner of the control signal may be multiple, for example, the processing module 320 may generate the control signal corresponding to each path of the adjusting group according to the microwave output signal of each path of the adjusting group acquired by the acquisition module 310, or may generate the control signal corresponding to each path of the adjusting group according to the microwave output signal of the multiple paths of the adjusting groups acquired by the acquisition module 310. In an example, if the acquisition module 310 monitors that the microwave device is not uniformly heated, the processing module 320 may determine that directions of microwave output signals corresponding to multiple paths of adjusting groups of the microwave adjusting device are relatively concentrated, at this time, a control signal generated by the processing module 320 may include a phase adjusting instruction corresponding to each path of adjusting group, so that the multiple paths of adjusting groups may respectively adjust phases of the microwave output signals of each path of adjusting group according to the control signal, thereby enabling the microwave adjuster 200 to generate microwave output signals in multiple directions, and enhancing uniformity of heating of the microwave device. In another example, the acquisition module 310 monitors that the operating temperature generated by the microwave output signal of a certain path of adjusting group in the microwave adjuster 200 is higher, and at this time, the processing module 320 may include a power amplifier adjusting instruction corresponding to the path of adjusting group in the control signal, so that the path of adjusting group may adjust the gate voltage of the power amplifier of the path of adjusting group according to the control signal, thereby reducing the operating temperature generated by the microwave output signal of the path of adjusting group and improving the heating flexibility of the microwave device.
