Основная компоновка промышленного панельного ПК:
1. Полностью-стальное шасси Полностью-стальное шасси IPC разработано в соответствии со стандартом, который включает защиту от -ударов,-вибрации, защиту{{5 }}электромагнитные помехи и могут быть оснащены пассивной объединительной платой, совместимой с-шиной ПК.
2. Пассивная объединительная плата Слот пассивной объединительной платы состоит из нескольких слотов SA и шины ПК. Количество и расположение слотов ISA или PC следует выбирать в соответствии с требованиями. Доска представляет собой четырех-слойную компоновку с двумя слоями в центре. Разделенный на слой земли и слой питания, этот метод компоновки может уменьшить взаимные помехи логических индикаторов на плате и уменьшить импеданс источника питания. Объединительная плата может быть вставлена в исходные платы, включая платы ЦП, платы производительности, платы управления, O-карты и т. д.
3. Промышленный источник питания представляет собой импульсный источник питания, а баланс и время бесперебойной работы достигает 250,000 часов.
4. CPU card There are many kinds of CPU cards in PC, which can be divided into long cards and half-length cards according to the size, and the processor can be divided into 386, 486, 586, Pl, PIII motherboards according to the size, users can choose according to their own needs. . Its main features are: working temperature 0-60 degree : equipped with a "watchdog" timer: low power consumption, 5V25A when very large.
5. Другие аксессуары Другие аксессуары ПК в основном совместимы с ПК, в основном это ЦП, память, видеокарта, жесткий диск, дисковод, клавиатура, мышь, CD-ROM, дисплей и т.д. К отечественным производителям промышленных планшетных ПК относятся EVOC, North China Industrial Control, Advantech и Ailesi. Зарубежные промышленные планшетные компьютеры Siemens очень хорошо-известны. Промышленный корпус планшета имеет длину 19 дюймов и высоту 4U.
6. Suitable for the platform At present, IPC has been widely used in all aspects of industry and people's life. For example: control the scene, road and bridge tolls, medical treatment, environmental protection, communication, intelligent traffic monitoring, voice, queuing machine, POS, CNC machine tools, fuel dispenser, finance, petrochemical exploration, field portable, environmental protection, military industry, electricity, railway, highway, Aerospace, subway, etc.
Features of industrial tablet PC: Generally speaking, industrial tablet PC is a computer specially designed for the industrial site, and the industrial site generally has a violent touch, and the industrial site generally has a violent touch, with a lot of dust, and a high Electromagnetic field force disturbance and other characteristics, and the general factory is working continuously, that is, there is generally no rest in a year. Therefore, the industrial tablet computer must have the following characteristics compared with the general computer: the chassis adopts the steel structure, and has high anti-magnetic, dust-proof and anti-strike capabilities. There is a special bottom plate in the chassis, and there are PC and ISA slots on the bottom plate. There is a special power supply in the chassis, and the power supply has strong anti-interference ability. Requires the ability to work continuously for a long time. Generally, a standard chassis that is easy to install is used (4U standard chassis is more common). Note: Except for the above features, other foundations are similar. In addition, because of the above professional characteristics, industrial tablet computers of the same grade are more expensive than the general ones, but generally not much different.
Compared with general-purpose computers, the main characteristics of industrial tablet computers are as follows: high reliability. Industrial tablet PCs are often used to control the continuous manufacturing process. During the operation period, no downtime inspection is allowed, and the occurrence of obstacles will cause quality problems and even manufacturing problems. Therefore, industrial tablet PCs are required to have high reliability, low failure rate and short after-sales time. Timeliness is good. The industrial tablet computer must timely control the changes of various parameters of the tool in order to control and monitor the manufacturing process in time. When errors or obstacles are found in the process parameters, an alarm and punishment can be issued in a timely manner. Usually industrial tablet PCs are equipped with real-time multi-task operating system and infix system. Situational compliance.
Due to the insidious environment of the industrial site, industrial tablet PCs are required to have strong environmental adaptability, such as high requirements for temperature/humidity changes: with the ability to prevent dust, corrosion, and shock from being touched: with good electromagnetic compatibility and high Anti-interference capability and high common mode suppression capability. Rich input and output templates. The industrial tablet computer is quite a set of process instruments, dealing with various lights, and requires rich multi-function input and output supporting templates, such as analog, digital, pulse and other input and output templates. The system has good extension and openness. The extended nature of the system is beneficial to the improvement of the automation level of the factory and the continuous expansion of the control range. Adopt an open system layout to facilitate system extension, software upgrade and exchange. Master software package is powerful, with convenient interpersonal interaction, rich screen, good timeliness and other functions: with system configuration and system production function: with timely and experienced trend record and actual function: with timely and experienced trend record and performance function : It has the functions of real-time alarm and accident recall; it has rich control algorithm. The system communication function is strong, and the industrial control system is generally required to be able to form a large-scale computer control system with remote communication function. In order to meet the timeliness requirements, the communication page speed of the industrial tablet computer should be high, and it is in line with foreign standard communication protocols. redundancy.
В местах с высокой надежностью промышленные планшетные компьютеры требуют двойной-машинной работы и резервных систем, включая двойные-станции управления, двойные{2}}операционные станции, двойную-сетевую связь. , системы с двумя источниками питания, сдвоенные источники питания и т. д., с функциями переключения двух-машин, двойным-программным обеспечением для мониторинга машин и т. д., чтобы система никогда не прерывала работу.
