Near Phoenix, Arizona, in the southwestern United States, there is a semi-underground bungalow building. This house is the first electronic residence in the United States built by the American Motorola Semiconductor Company. This electronic house is controlled by an electronic system composed of five microcomputers. The electronic house faces south and faces north, and has a porch, living room, living room, dining room, bedroom, bathroom, laundry room, kitchen, garage and swimming pool. Its ridge-like roof is equipped with an array of solar cells. The door of this house faces a gentle slope built according to the terrain, and a solar collector is installed on the sunny side. This set of solar cell arrays and thermal collectors provides the electrical and thermal energy needed by the house. The windows on both sides of the roof are made of translucent optical glass, which allows light to enter, but most of the heat generated by direct sunlight is rejected outside the window, which can keep the interior warm in winter and cool in summer. However, the work of controlling indoor temperature and humidity is mainly done by computers. In addition, computers also do many tasks such as energy saving, anti-theft, fire prevention, and information storage. The owner of the house can pre-set the indoor temperature and humidity for every day or even a week, compile it into a program and store it in the computer. The temperature and humidity sensors installed in the house input the relevant parameters detected through a converter with 32 channels into the microcomputer in charge of air conditioning. After analysis and comparison, this computer issues instructions to control the automatic opening and closing of doors and windows to maintain the predetermined temperature and humidity indoors. In addition to this passive air conditioning that does not consume electricity, computers can also use active air conditioning. The residence is equipped with several optional air-conditioning and heating systems. Refrigeration devices or cooling water circulation devices can be used to cool down, and solar collectors or electric heaters can be used to heat up. The water temperature of the swimming pool is also adjusted by computer-controlled solar collectors and water pumps to maintain a suitable water temperature. A microcomputer is responsible for the management of lights and various electrical facilities in the house. It switches lights on and off regularly, checks the power usage of each household appliance separately, and records the time and energy consumed to keep the total power consumption within a fixed value. There is no door lock visible in this modern electronic house, but no one who knows its secrets can get in. There is a keypad punching machine outside each door. Just press a few keys, enter the correct code, and the electronic interlocking mechanism opens, and the door will quietly open. These door openings use "passwords" that the owner of the house can change every few days, or even every few hours, and the "passwords" that can be changed are unlimited. Of course, a skilled thief will inevitably sneak in illegally, but if he can get in, getting out will not be so easy. Each room is equipped with a motion detector. Once an uninvited guest is discovered, the microcomputer that performs the security and defense function will suddenly turn on the lights. The speaker installed at the door of each room will sound an alarm. The computer will automatically alert the police and display the location of the uninvited guest on the surveillance screen. Each room is also equipped with smoke detectors. When a fire occurs, the microcomputer will automatically cut off the power supply and alert the fire brigade. What is interesting is the microcomputer in charge of fire protection and anti-theft. As long as a special code is entered into it, the computer's speech synthesizer will replace the host and thank the guests through the loudspeaker. In addition to storing information and programs related to their work, the computer memory in this house can be used by the owner of the house to compile a "memo calendar" at any time. Input sporadic information such as holidays, appointments, things to do, items that need to be purchased, etc. cataloged by date. Just press the button every morning, and the TV screen will remind you what you should do today. The five microcomputers, closed-circuit television systems, various sensors, etc. inside this house are connected by special communication lines into an electronic control system. The advent of the microprocessor opened up a new field of computer application in the home. Home computers are all microcomputers. Microcomputers, which are mainly composed of microprocessors, firstly showed their talents in household appliances, and then showed their talents in residential air conditioning and security. It is expected that they will also show their talents in playing the role of "electronic housekeeper" in household account management, education, entertainment, medical care, etc. Nowadays, electronic homes in the United States are being improved. In addition to the above-mentioned centralized functions, they are striving to add appropriate software parts in education, entertainment, medical and other aspects to realize the so-called "family common" full-featured electronic homes. In addition, the next round of electronic housing design will highlight network functions, making this kind of housing a member of the "global village".
