Middex-Electronic controller Germany Middex-Electronic model Middex-Electronic price

The Middex-Electronic controller integrates the basic components of an electronic computer, such as the central processing unit (also known as the CPU, mainly composed of an arithmetic logic unit and a control unit), memory, bus, and input/output interfaces, onto a single silicon chip using integrated circuit technology. Due to the small size of the microcontroller (only finger-sized) and its powerful functionality (equivalent to a simple computer), it is widely used as a controller in electronic devices. From advanced defense weapons like missiles and rockets to modern household appliances such as televisions and microwave ovens, microcontrollers are invariably used as controllers. Therefore, from a control perspective, it is often referred to as a single-chip controller. The operation of a single-chip microcontroller relies on software, which consists of pre-designed programs stored in memory.

Middex-Electronic controller principle

For all electronic devices equipped with single-chip microcontrollers, the working principle naturally depends on the specific device. However, the most basic principle is: 1) receiving information from the external environment via input interfaces and storing it in memory. This information mainly includes two parts: data from sensors such as temperature and pressure sensors; and manual input from human intervention, such as switch or button operations. 2) The central processing unit in the single-chip microcontroller performs high-speed arithmetic processing on the input data according to the program. 3) The results of the processing are sent via output interfaces to control actuators, such as relays, motors, and light bulbs. This process repeats continuously, meaning the microcomputer in the system constantly monitors various information and makes timely adjustments to ensure normal system operation.

Middex-Electronic controller applications

Since smart electronic devices are often carried outdoors, their energy consumption requirements are very high. Therefore, energy-saving control modules are often designed to extend the standby time of smart electronic devices. The application of microcontroller technology in energy-saving control is mainly divided into the following aspects: First, when smart electronic devices are used outdoors, they are mostly in a light-load mode. In this case, energy-saving control is needed to further reduce power consumption while ensuring basic functions. By collecting data from smart electronic devices, the microcontroller can roughly infer that the current device load is low, allowing it to reduce voltage and current output to achieve energy savings. Second, the microcontroller can control the rhythm of energy consumption. For example, in the Xiaomi Mi Band, digital data such as heart rate, sleep, and step count are collected and stored locally, then reported at a minute-level frequency. When information is not being reported, the device is in a low-energy state. When reporting information, there is some network transmission consumption. The microcontroller can control the energy consumption rhythm, keeping the band in a low-energy state for most of the time, allowing standby time to reach more than seventy-two hours.
