Phone lockers for all of us not in a strange, because we can seen in supermarkets, shopping malls, railway stations and other places, can not help us store some items easy to carry, the operation is relatively easy to Ha, of course, the credit Thanks to the control system, there is no good control system, and it is no good at using beautiful cabinets. Next, let Xiaobian introduce the control system of the mobile phone locker.
There is an important device in the mobile phone locker, which is sent to the SCM. What is a SCM?
Microcontroller (Microcontrollers) is an integrated circuit chip using VLSI technology is the central processing unit CPU having a data processing capability, random access memory RAM, a read only memory ROM, a variety of I / O ports and interrupt system, the timer / counter functions (display driving circuit may further include a pulse width modulation circuit, an analog multiplexer, a / D converter circuit, etc.) into a small but complete configuration of a microcomputer system on a silicon wafer, in the industrial Wide application in the field of control. From the 80s of the last century, from the then 4-bit, 8-bit microcontrollers, to the current 300M high-speed microcontroller.
Contemporary microcontroller systems are no longer only developed and used in bare metal environments. A large number of dedicated embedded operating systems are widely used in a full range of microcontrollers. The high-end MCUs that handle the cores of PDAs and mobile phones can even use dedicated Windows and Linux operating systems directly.
SCM, also known as a single-chip microcontroller, is not a chip that performs a certain logic function, but integrates a computer system into a single chip. Equivalent to a miniature computer, compared with the computer, the microcontroller only lacks I/O devices. In a nutshell: A chip becomes a computer. Its small size, light weight, and low price make it easy to learn, apply and develop. At the same time, learning to use a microcontroller is a good choice for understanding computer principles and structures.
The use of single-chip microcomputer has been very extensive, such as smart meters, real-time industrial control, communications equipment, navigation systems, household appliances and so on. Once the MCU to spend a variety of products, you can play the efficacy of product upgrades, often preceded by the adjective before the name of the product - "smart", such as smart phones lockers.
Cell phone locker on a single machine features
The microcontroller has a small size, low power consumption, control powerful, flexible extension miniaturization and ease of use, various forms MCU may constitute a control system, data acquisition system, a communication system, signal detection system, a wireless sensing system, monitoring and control System, robot and other application control systems. For example, intelligent management of factory assembly lines, intelligent control of elevators, various alarm systems, and networking with computers constitute secondary control systems.
The single camera is suitable for the mobile phone locker so that the mobile phone locker is continuously developed, the update speed is fast, and the application prospect is wide. Because the single-chip microcomputer combines software and hardware components, it is small in size, flexible, and highly integrated. It can be easily embedded in other systems.
