Embodiment Construction

[0014] Example. This example takes the Sharp R-3E56 microwave oven as the prototype, and monitors it with a computer. In the signal detection and conversion device, the single-chip microcomputer of the single-chip unit 1 adopts 8751, and the output pins P00-P07 of the 8751 are connected to the microwave oven button control circuit through electronic switches (U4A-U4D, U5A-U5D), and then connected to the main control of the microwave oven. The state signal input end of the chip U1 constitutes the output part of the microwave oven interface unit 2; the input pins P10-P17 of the 8751 are connected to the state signal output end of U1 to constitute the input part of the microwave oven interface unit 2. The RXD pin and TXD pin of 8751 perform two-way data transmission with the computer through the computer interface unit 3 formed by the standard serial port.

[0015] After the computer sends a signal to control the microwave oven, the 8751 MCU receives the serial data from the RXD...

Abstract

A method for monitoring microwave oven by computer features a signal detecting-converting device is used, which is composed of single-chip microprocessor unit, microwave oven interface unit, and computer interface unit. The signals can be converted and transmitted between microwave oven and computer by means said device. Its advantages include flexible monitor and intelligent and remote control.

Description

technical field [0001] The invention relates to a monitoring method and a device for a microwave oven, in particular to a method and a device for monitoring a microwave oven by using a computer. Background technique [0002] At present, the monitoring of microwave ovens is mainly realized through buttons. The key monitoring is intuitive, but it must be operated on site. Moreover, remote monitoring cannot be realized, and the level of intelligent control is also very limited. Contents of the invention [0003] The purpose of the present invention is to give full play to the functions of computers owned by more and more families, and to provide a method for monitoring microwave ovens with a computer and a used signal detection and conversion device. By using the method and device of the invention, the control of the microwave oven can be intelligentized, and remote monitoring can also be realized. [0004] In order to achieve the purpose of the above invention, the techni...
