Vantagens e aplicações do computador industrial embarcado

Embedded industrial computer is industrial computer. The so-called industrial computer is different from our personal PC. Essentially it's still a computer. It is called an industrial computer only because it is used in an industrial scene. Of course, it is far better than a personal PC in terms of stability and reliability.

The embedded industrial computer can also customize different functions according to different usage scenarios, and has a very rich expansion of i/o functions. The running system has also been modified. Very streamlined.

Embedded industrial computer, more fashionable name is box computer or fanless industrial computer, embedded industrial computer is a compact computer specially designed for industrial sites.

Embedded industrial computers often operate in harsh environments and have higher data security requirements. Therefore, industrial computers are usually specially designed for reinforcement, dust-proof, moisture-proof, corrosion-proof, and radiation-proof.

Embedded industrial control also has very high requirements for scalability, and the design of the interface needs to meet specific external devices. Therefore, in most cases, the industrial computer needs to be customized separately to meet the demand.

Ordinary PCs are mainly civilian-grade, and there are not many requirements in the physical environment. Industrial PCs are generally used in places with harsh environments, and have higher requirements for data security. Therefore, industrial PCs are usually specially designed for reinforcement, dust-proof, moisture-proof, corrosion-proof, and radiation-proof.

Next, we analyze the advantages and differences between ordinary PCs and industrial computers from the aspects of functionality, heat dissipation scheme, stability and reliability, reliability, real-time performance, scalability, and compatibility of ordinary PCs and industrial computers:

1. Functionality:
Industrial personal computers are specific needs and have specific functions, while ordinary PCs mainly meet the needs of the public and have multiple functions.

2. Cooling scheme:
Industrial computer motherboards pay attention to heat dissipation efficiency, while ordinary PCs focus on appearance.

3. Expandability:
Because the industrial computer adopts the base plate + CPU card structure, it has strong input and output functions, and can expand up to 20 boards, which can communicate with various peripherals and boards on the industrial site, such as road controllers, video surveillance systems, and vehicles. Detectors, etc. are connected to complete various tasks.

4. Stability and reliability:
Industrial personal computers have very high requirements for stability. The functions emphasized by PCs are satisfactory, and the performance can be avant-garde, but the stability is far inferior to industrial personal computers. As for the service life, it depends on the configuration of all aspects of the product. In terms of reliability, the industrial computer has dust, smoke, high/low temperature, humidity, vibration, corrosion and rapid diagnosis and maintainability. Its MTTF is more than 100,000 hours, while the MTTF of ordinary PCs is only 10,000-15,000 hours.

5. Compatibility:
The industrial control function can use resources such as ISA and PCI at the same time, and supports various operating systems, multi-language assembly, and multi-tasking operating systems.

6. Reliability:
The industrial computer has dust, smoke, high/low temperature, humidity, vibration, corrosion and rapid diagnosis and maintainability. Its MTTF is more than 100,000 hours, while the MTTF of ordinary PCs is only 10,000-15,000 hours.

Seven, real-time:
The industrial computer performs real-time online detection and control of the industrial production process, responds quickly to changes in working conditions, and performs timely collection and output adjustment (the watchdog function is not available in ordinary PCs), self-resetting in case of distress, ensuring system stability. normal operation.

application:
1. Application of embedded industrial computer in the field of patrol robots
With the development of artificial intelligence technology, the development of patrol robots is gradually rising. The intelligent patrol robot uses the technology of the Internet of Things, integrates laser + inertial navigation + GPS positioning technology, realizes intelligent patrol, and realizes the identification, detection and analysis of people, things and objects through various sensors and thermal imaging technology , You can also broadcast reminders or publicize related content through language, which greatly liberates manpower and improves work efficiency. According to different indoor and outdoor patrol scenarios, different types of indoor and outdoor patrol robots, fixed-point patrol server robots, and special department-specific robots can be selected.

The robot control system is the brain of the robot and the main factor that determines the function and performance of the robot. The control of the robot's movement position, posture, trajectory, and operation sequence in the workspace is inseparable from the support of the industrial computer. Due to the relatively harsh working environment of the patrol robot, the requirements for the hardware of the control system are more stringent, and an industrial computer with excellent processing performance that can adapt to a wide temperature environment is required. The compact mini size and durable fanless design of the embedded industrial control host can withstand the requirements of harsh industrial environments to ensure stability and durability, and truly achieve small body and large energy!

2. Application of embedded industrial computer in the field of machine vision
Machine vision system is to use machines instead of human eyes to make various measurements and judgments. It is an important branch of computer science. It integrates technologies in optics, mechanics, electronics, computer software and hardware, etc. Recognition, artificial intelligence, signal processing, optomechanical integration and other fields. The rapid development of technologies such as image processing and pattern recognition has also greatly promoted the development of machine vision. Automated visual inspection solutions enable improved product quality in the food and beverage, pharmaceutical, automotive, semiconductor and other industries. From the display position of fixed to mobile video cameras, high-speed three-dimensional analysis, etc., all need to use machine vision to replace manual work.

In principle, the machine vision system is mainly composed of three parts: image acquisition, image processing and analysis, output or display. As the main control device of the management center of the machine vision system, the embedded industrial control host is used with image analysis and processing software to calculate features. According to the calculation results, the industrial computer controls the actuator to perform actions such as classification, elimination, and alarm.

3. Application of embedded industrial computer in intelligent transportation industry
The fully automatic electronic toll collection system (ETC, Electronic Toll Collection) is one of the service functions of the intelligent transportation system. The ETC system uses the automatic vehicle identification technology to complete the wireless data communication between the vehicle and the toll station, and carries out the automatic induction identification of the vehicle and the exchange of related toll data. The computer network is used to process the charging data, so that a fully automatic electronic charging system can be realized without parking or setting a charging window.

The embedded industrial control host is mainly used in the lane controller of the expressway toll system. Through the serial port, DIO and video acquisition card, the on-site roadside read-write controller (RSU), on-board unit (OBU), traffic lights, alarms, and character superimposition Toll controller, fee display, automatic railing machine, canopy signal light, vehicle detector, ground sense coil, camera, card reader, etc. are integrated to control to realize charging. And control the lift and drop bars, so as to achieve the purpose of vehicle passage.

The ETC driveway machine industry tends to be integrated and integrated design, and the requirements for internal space are more stringent. The embedded industrial control function can well meet the needs of integrated and miniaturized field applications. The wide temperature fanless design can effectively improve the long-term operation requirements. reliability and stability.
