EVOC IPC common faults and solutions

Memory is one of the most important components in industrial motherboards, which is mainly used to temporarily store the computing data in the CPU and the data exchanged by external memory. In the operation of industrial computers, there may be incompatibility between memory and industrial motherboards. The following is an introduction to the incompatibility of memory with industrial motherboards ...

1. Investigation and Review The way to check is to check whether the appearance of the industrial motherboard and the parts are abnormal. When overhauling the industrial motherboard, the first thing to do is to investigate whether the capacitors on the industrial motherboard are bulging, leaking or severely damaged; The resistor and capacitor pins are ...

The temperature is not suitable for the maintenance of the hard drive, if the case temperature reaches 30 degrees Celsius, the temperature of the internal hard drive will reach 40 degrees or higher. We can briefly DIR our industrial computer to achieve the effect of reducing the ambient temperature. 1. Replace high-power CPU and hard disk fan (hard disk fan to...

The main categories of industrial computers are: IPC (PC bus industrial computer), PLC (programmable control system), DCS (loose control system), FCS (field bus system) and CNC (numerical control system). 1、IPC ...

Vibrating Due to the different application occasions of embedded industrial computers, such as wall-mounted and vehicle-mounted, the vibration may be strong in the process of use, and special anti-vibration treatment is required for embedded industrial computers, such as the use of solid state drives, memory and other accessories for reinforcement treatment. compatibility ...

Downtime is a common fault of the industrial computer, and the ability to solve the downtime can ensure the high reliability and real-time function of the industrial computer. The following is an analysis of the common causes and solutions of industrial computer downtime. 1. Too much dust causes downtime ...

During the use of the industrial computer, the user mistakenly deleted the system file, resulting in an abnormal function of the industrial computer; The industrial computer was invaded by a virus Trojan horse, which led to problems in the system; Some fault prompts frequently pop up on the desktop, and the industrial computer needs to be reinstalled in the system. Strictly speaking, the industrial computer ...

First of all, let's start with the structure of the industrial computer. Our industrial computers are made of all-aluminum alloy structure, which is completely sealed, and there is no electric fan inside for heat dissipation, so there is usually some heat on the outside of the IPC case. Demonstrate that the CPU or other electronic data can be used to ...

Appearance: The industrial computer is generally a closed chassis, with industrial wind planning, solid structure, waterproof, dustproof, seismic and other characteristics. Desktops, on the other hand, generally use open chassis, general wind planning, and relatively simple structure. Function: Industrial computer generally uses embedded system planning, ...

The capacitive screen can be simply regarded as a screen composed of four layers of composite screens: from the outside to the inside, they are glass protective layer, conductive layer, non-conductive glass screen, and conductive layer. The innermost conductive layer plays the role of shielding the internal electrical signal, and the middle conductive layer has direct ...

Fault 1: The mouse is only moved in a small area or is forbidden to touch This usually happens when you first install the drive, run the contact screen calibration procedure. After changing the resolution of the industrial tablet, the contact screen calibration procedure is also run. Fault 2: Mouse 1 ...

One. How to use the case fan correctly --- importance of the direction of the case fan If you find that the fan is installed, the heat dissipation performance of the host is not improved or even becomes worse, it is likely that the direction of the fan is reversed.

With the development of a new generation of information technology such as artificial intelligence, big data, and the Internet of Things, the industrial control system has begun to develop in the direction of intelligence, networking, and digitalization. Embedded industrial computer is a major development in recent years.

Parallel interface, referred to as parallel port. The parallel port of the industrial computer uses a 25-pin D-connector. The so-called "parallel" means that 8-bit data is transmitted together through parallel lines, so that the data transmission speed is greatly improved, but the length of the parallel transmission line is limited, and due to the increase in length, the disturbance will increase.

Compared with traditional PC computers, industrial computers are more used in harsh environments, so industrial computers have more and more stringent requirements in terms of easy maintenance, heat dissipation, dustproof, product cycle, size, etc., therefore, it has created the unique characteristics of industrial computers. ...

1. PCI is the abbreviation of Peripheral Component Interconnect (Peripheral Component Interconnect specification), which is the main expansion slot of industrial computers, and it is also the type of slot with the most on the board of industrial motherboards.

In fact, the industrial computer is not much different from the general computer, but the power supply and motherboard are nominally more stable and reliable than the general computer, after all, the requirements of the industrial site are a little higher than the civilian one, and the so-called industrial computer encounters similar problems to the general computer, such as the black screen of the crash can not be started ...

With the growing demand for new technologies, in the development of touch products, capacitive touch screens are becoming larger and larger, and the use of writing devices similar to paper and pen has become more intuitive and convenient. The most common way manufacturers can support the function of a stylus is to use an active stylus ...

With the modernization, high-tech and sophistication of electronic equipment, it is necessary to rely on an automatic testing system to complete the on-site rapid testing of electronic equipment. The radar automatic test system is based on the "PCI bus test software channel", aiming at the needs of the radar machine test.

Serial port is a very common device communication protocol on industrial motherboards, and most industrial motherboards contain more than two serial ports based on RS-232. The serial port sends and receives bytes on a bit-by-bit basis, which is slower than parallel communication on a byte-by-byte basis, but the serial port can be used in the use of a single wire.
