[0002] The oven is a sealed electrical appliance used to bake food. The oven power board is the most important circuit board used to control the function of the oven. Before the oven leaves the factory, it is necessary to test the power board to see if the function of the power board is normal. At present, the inspection is carried out manually, and each indicator is judged manually. Because workers are affected by their education background and emotions, they often make mistakes in judgment, resulting in a greatly reduced pass rate and low work efficiency. Restricted the production efficiency and qualification rate of the oven

Embodiment Construction
[0019] A fully automatic detection circuit for an oven power board, including a main control circuit, the main control circuit is connected to a display circuit, a buzzer circuit, a communication circuit and a relay test circuit, the main control circuit includes an MCU, and the display circuit includes a digital display screen, The buzzer circuit includes a buzzer, and the relay test circuit includes an LED light.
[0020] The MCU model is R5F100FCAFP#X0, of which pins 39, 40 and 41 are connected to the display circuit, pins 29 and 30 are connected to the communication circuit, pins 32 are connected to the buzzer circuit, and pins 16-22 are connected to the relay test circuit. The version number is sent to the MCU, and the MCU makes a judgment. If the version number is consistent with the issued program, proceed to the next step. If the version number is inconsistent, the digital display will display E1, and the buzzer will sound for a long time;
[0021] Next, the communicat...

The invention includes a fully automatic detection circuit for an oven power board, including a main control circuit, which is connected to a display circuit, a buzzer circuit, a communication circuit and a relay test circuit. The invention can replace manual detection and judgment. When there is a problem with the power board of the oven, the buzzer of the detection circuit can automatically sound a long alarm to notify the workers to carry out further detection, thereby avoiding the artificial judgment of the workers and improving the detection efficiency and detection accuracy.
Description
technical field [0001] The invention relates to a fully automatic detection circuit and a detection method for an oven power board. Background technique [0002] The oven is a sealed electrical appliance used to bake food. The power board of the oven is the most important circuit board used to control the function of the oven. Before the oven leaves the factory, it is necessary to test the power board to see if the function of the power board is normal. At present, the inspection is carried out manually, and each index is judged manually. Because workers are affected by their education background and emotions, they often make mistakes in judgment, resulting in a greatly reduced pass rate and low work efficiency. Restricted the production efficiency and qualified rate of oven. Contents of the invention [0003] In view of the present situation of the above-mentioned prior art, the technical problem to be solved by the patent of the present invention is: to provide a detect...
