Task
Based on the 51 single-chip microcomputer, simulate the whole process of the washing machine to complete the following:
- Power supply circuit, designed to meet the requirements of the power input
- Washing machine weight detection module to detect the weight of clothes in the drum
- Water level detection, used to control the amount of water added to the washing machine
- Washing machine lid detection for safety detection to prevent accidents
- Button control, switch between multiple laundry modes
- LED digital tube displays the remaining washing time
- LED Status Knowledge Current Mode
- Buzzer alarm, when there is an abnormal situation such as the lid of the washing machine is opened halfway
- Inlet and outlet water control, relay solenoid valve
- Washing Motor Control

实现对洗衣机整个洗衣过程的控制，包括进水、洗涤、漂洗、排水、脱水五个过程。
标准：洗涤60秒，漂洗20秒，脱水10秒。---90秒
快速：洗涤40秒，漂洗20秒，脱水10秒。---70秒
轻柔：洗涤30秒，漂洗15秒，脱水10秒。---55秒
洗涤和漂洗：电机正转3秒，暂停2秒，反转3秒
