Common sense of embedded industrial control touch screen all-in-one machine nowadays, smart phones and embedded industrial control touch screen all-in-one machines are indispensable electronic products in our daily applications. In the field of industrial applications, industrial tablet computers and embedded fanless industrial personal computers are in the forefront. These products belong to one kind of electronic computer. Since they are electronic computers, they all have core components such as CPU, GPU, RAM, ROM, etc. Today we will talk about the difference between RAM and ROM. RAM (Running memory)And ROM (Storage memory) The performance of embedded fanless industrial personal computer products is also very important. RAM (Running memory)Is through some kind of capacitor (DRAM, SRAM or RRAM) If data is stored, the data will disappear immediately after power failure, but the data throughput speed is very fast. ROM is the storage memory that can save data after power failure and provide extremely fast access when needed. We will not delve into it here. The usual solid state drive for industrial tablets (SSD) U disk and SD card use a storage medium called NAND, traditional storage media and mechanical hard disk (HHD) , That is, the traditional CD storage, can keep the stored data from being lost after power failure, and can be used for storing data. Embedded industrial control touch screen integrated machine has been widely used in many fields such as transportation, electric power, metallurgy, communication, aerospace, petrochemical and so on. However, in industrial fields requiring human-computer interaction, the application and advantages of industrial tablet computers are especially prominent. Its performance is more and more close to the traditional embedded industrial control touch screen integrated machine, and its expansion performance is also increasingly diverse and rich. As one aspect of the finalized extended application, extended acquisition data Board and extended Switch device board are more common. Today, we will make a brief explanation on expanding the application of switching device boards, especially those switching devices: Current-type full-control device BJT: continuous base current control is turned on, if the base current is 0, it is turned off; The switching frequency is moderate; Bipolar; Current-type semi-control device SCR: Pulse Gate current control is turned on, and trigger signal cannot be controlled to be turned on and off; Low switching frequency; Bipolar; Current-type full-control device GTO: Positive Pulse Gate current control is turned on, negative pulse gate current (Larger)Control shutdown; Low switching frequency; Bipolar; Voltage type full control device P- MOSFET: positive continuous gate voltage control is turned on, negative continuous gate voltage control is turned on and kept off; High switching frequency; Unipolar; Voltage-type full-control device IBGT: positive continuous gate voltage control is turned on, negative continuous gate voltage control is kept off; High switching frequency; Bipolar; Voltage type full control device MCT: positive pulse voltage control is turned on and negative pulse voltage control is turned off; Higher switching frequency (Below IGBT); Bipolar; Voltage type full control device SIT: continuous voltage control off and on; High switching frequency; Unipolar; The slogan of the Internet of Things is ringing year by year, and many new technologies and products are constantly being applied. As a key part of the control system, computers are essential to execute and output instructions. First of all, from the working environment, the control system is generally in the computer room, the dust is big, the environment is general, this is the industrial tablet computer can adapt, the commercial computer is absolutely playable. If nothing else, the accumulated dust will also make commercial computers unable to work. Therefore, in terms of environmental adaptability, industrial computers will be better than commercial computers. Secondly, in terms of the intensity of work, commercial computers are also slightly insufficient in this respect because they have to keep working at all times and have higher requirements for heat dissipation and hardware. Industrial tablets, on the other hand, can maintain good heat dissipation and work continuously for a long time. Therefore, from the above point of view, the embedded industrial control touch screen all-in-one machine is more suitable for the field of internet of things than commercial computers.
