Application of Data Acquisition IO Module in Thermal Power Plant System3636R Invensys Triconex system
The Ethernet IO module is a data acquisition and control device. It uses Ethernet as a communication method to transmit data from various industrial control sensors and actuators to computers or other devices for management and monitoring. As a modern energy supply base, thermal power plants need to widely apply various intelligent control technologies to improve operational efficiency, reduce costs, and improve safety. In this context, the application of barium rhenium Ethernet IO modules is particularly important.
In the application of thermal power plants, the main function of the barium rhenium Ethernet IO module is to achieve real-time monitoring and control of the production process. By connecting to various sensors and actuators, the barium rhenium Ethernet IO module can collect real-time environmental parameters, machine operation status, and other data of the thermal power plant. By analyzing and processing these data, commanders can understand the operation of the thermal power plant and make corresponding adjustments. Compared to traditional automatic control systems, the barium rhenium Ethernet IO module has the advantages of stronger flexibility, faster reaction speed, and higher accuracy, which can greatly improve the operational efficiency and reliability of thermal power plants.
The real-time monitoring and control of thermal power plants require many capabilities of barium rhenium Ethernet IO modules. Here are several common application scenarios:
Firstly, the barium rhenium module can monitor parameters such as gas flow and water flow in thermal power plants. These parameters are crucial for ensuring the normal operation of the thermal power plant. Once these parameters undergo abnormal changes, the DO channel can be connected to the barium rhenium Ethernet IO module, and the alarm signal will immediately sound to remind the command personnel to handle it. Meanwhile, due to the fact that the barium rhenium Ethernet IO module can collect these data in real-time and transmit it to the monitoring system for recording, it can provide better technical support for quality management in thermal power plants.
Secondly, the barium rhenium Ethernet IO module can also monitor the operating status of mechanical equipment in thermal power plants. This includes parameters such as temperature, pressure, vibration, etc. By monitoring and analyzing these parameters, the barium rhenium Ethernet IO module can detect machine equipment faults in a timely manner, thereby avoiding the expansion of losses. In addition, during machine equipment maintenance, historical data recorded by the barium rhenium Ethernet IO module can be used to develop more scientific and reasonable maintenance plans, reduce maintenance costs, and improve maintenance efficiency.
Finally, the barium rhenium Ethernet IO module can also help thermal power plants achieve distributed control. We can remotely control and monitor multiple areas of the thermal power plant by connecting multiple barium rhenium modules to a network. This not only reduces the on-site debugging of equipment, but also strengthens the evaluation of equipment reliability.
In summary, the barium rhenium Ethernet IO module has unique advantages in real-time monitoring and control of thermal power plants. It can help command personnel monitor machine data in real-time, discover abnormal information, take timely measures to avoid impacts, and improve production efficiency and safety.
Remote IO modules based on Ethernet communication are widely used in the field of industrial IoT
With the development of IIOT (Industrial IOT) industrial Internet of Things technology, many traditional assets need to be connected to the internet to achieve unified data collection, analysis, processing, and storage, breaking the traditional phenomenon of device information silos. Therefore, the MQTT Ethernet IO acquisition module M160T, which supports the Internet of Things protocol, is able to unleash its potential by being compatible with existing devices and able to connect to IoT platforms. The MQTT Ethernet IO acquisition module will be widely used in industrial IoT, such as smart property, smart parks, smart factories, smart transportation, smart water conservancy, smart agriculture, smart campuses, smart communities, smart distribution, smart water conservancy, and many other industries.
Ethernet communication technology is a mature communication technology that has been widely applied. Therefore, Ethernet communication is the first choice for enterprises to connect various assets to the Internet of Things platform. Its reasons are stable and reliable, mature technology, fast transmission speed, and fast construction wiring.3636R Invensys Triconex system
For traditional various assets, such as low-voltage distribution rooms, air compressor rooms, property and living pump rooms, street light control, liquid level collection, temperature and humidity collection, etc., through the MQTT Ethernet IO collection module, they can be quickly connected to the Internet of Things platform.
So, what characteristics do MQTT Ethernet IO modules need to have when used in IoT solutions? The details are as follows:
1. Actively connect to cloud platforms:
Based on the characteristics of Ethernet communication networking, the Ethernet IO acquisition module must support the TCP Client function, which is not only the TCP client function, so that the Ethernet IO module can actively connect to the IoT platform without the need for complex settings such as peanut shells;
2. Compatible with existing systems:
Support TCP Server and Modbus TCP protocol functions, which can be compatible with traditional upper computer systems or device access of HMI”s TCP client;
3. Access to IoT platforms:
Supports standard MQTT protocol and Modbus TCP protocol, and can be connected to various MQTT protocol IoT platforms such as Huawei Cloud and Alibaba Cloud, or traditional SCADA and DCS systems;
4. Rich IO interfaces and scalability:
There are various types of data to be collected on site, and it is necessary to support the collection of various devices such as 4-20Ma, RS485, DI, DO, etc. At the same time, it is also necessary to have the ability to read RS485 device instrument data or expand the functions of the IO acquisition module;
5. Easy installation method:
The volume of the control box is very limited, so it is necessary to use directly inserted and unplugged wiring terminals, as well as a rail installation method.
6. Industrial grade design
The industrial environment is harsh, and the Ethernet IO module must adopt an industrial grade design to ensure continuous and stable operation in harsh environments.
Through the MQTT Ethernet IO acquisition module, there is no need to replace various existing enterprise assets and the digital transformation of accessing IoT platforms can be quickly achieved. Therefore, the MQTT Ethernet IO acquisition module will be widely used in industrial IoT, such as smart properties, smart parks, smart factories, smart transportation, smart water conservancy, smart agriculture, smart campuses, smart communities, smart power distribution, smart water conservancy, and many other industries.
What is the function of an IO chip
Io generally refers to input and output devices, where I is the input and O is the output. The input to the IO port of the chip is the external signal transmission to the chip, while the output is the internal signal transmission to other devices. The input and output are relative. In short, in a broad sense, the control of input and output interfaces is called an IO chip, and network cards are also considered IO or array cards.
The CPU must read and write data to external registers or ROMs on RAM or other hardware through IO commands (such as input/output commands). For example, reading a keyboard involves accessing external registers on the keyboard through the 60H port, and the chip on the keyboard scans the keyboard. Pressing or holding down a key for a long time will cause the chip to generate corresponding scan or break codes, which will be written to the external register of the 60H port, so that the CPU can achieve the purpose of controlling the keyboard. Therefore, I think IO chips should refer to a large category. The CPU already has powerful IO instructions and corresponding control buses.
51 microcontroller IO port input and output mode_ Four usage methods for IO ports
The traditional 51 microcontroller IO interface can only be used as a standard bidirectional IO interface. If it is used to drive LED, it can only be driven by injecting current or using a transistor external expansion drive circuit.
Current injection method: LED positive pole connected to VCC, negative pole connected to IO port. If the IO is at a high level, the two poles of the LED are at the same level, and there is no current, the LED will turn off; IO is at low power level, current flows from VCC to IO, and LED lights up. But when you connect the positive pole of the LED to the IO interface and the negative pole to GND, placing the IO interface at a high level will cause the LED to light up. However, due to the insufficient pull-up capability of the IO interface, the brightness is not ideal. The following method can be used to solve this problem.
Push-pull working mode: The positive and negative poles of the LED are connected to two IO ports, and then the positive IO interface is set as the push-pull output, while the negative IO interface is set as the standard bidirectional current input. The push pull method has strong pull-up ability and can achieve high-level LED driving.
Four usage methods for IO ports3636R Invensys Triconex system
From the perspective of the characteristics of the I/O port, the P0 port of Standard 51 is an open drain structure when used as an I/O port, and in practical applications, a pull-up resistor is usually added; P1, P2, and P3 are all quasi bidirectional I/Os with internal pull-up resistors, which can be used as both input and output. The I/O port characteristics of the LPC900 series microcontroller have certain differences, and they can be configured into four different working modes: quasi bidirectional I/O, push pull output, high resistance input, and open drain.
Compared with Standard 51, the quasi bidirectional I/O mode differs in internal structure but is similar in usage. For example, when used as an input, it must first write “1” to set it to high level before reading the level state of the pin.!!!!! Why is it like this? Please refer to the diagram below for analysis.
The characteristic of push-3636R Invensys Triconex systempull output is that it can drive a large current regardless of whether it outputs high or low levels. For example, when outputting high levels, it can directly light up the LED (by connecting several hundred ohm current limiting resistors in series), which is difficult to achieve in quasi bidirectional I/O mode.
The characteristic of high impedance input mode is that it can only be used as an input, but it can obtain relatively high input impedance, which is necessary in analog comparator and ADC applications.
The open drain mode is similar to the quasi bidirectional mode, but there is no internal pull-up resistance. The advantage of open drain mode is good electrical compatibility. If the external pull-up resistor is connected to a 3V power supply, it can interface with a 3V logic device. If the pull-up resistor is connected to a 5V power supply, it can also interface with a 5V logic device. In addition, the open drain mode can also conveniently implement the “line and” logic function.
For the explanation of the above question, there is this information:
High resistance state is a common term in digital circuits, referring to an output state of a circuit that is neither high nor low. If the high resistance state is input into the next level circuit, it has no impact on the lower level circuit, just like not connected. If measured with a multimeter, it may be high or low, depending on what is connected afterwards.
High resistance states can be understood as open circuits during circuit analysis. You can think of it as having a very high output (input) resistance. His limit can be considered suspended.
Typical applications of high resistance states:
1. On the bus connected structure. There are multiple devices hanging on the bus, and the devices are connected to the bus in a high impedance form. This automatically releases the bus when the device does not occupy it, making it easier for other devices to gain access to the bus.
2. Most microcontroller I/O can be set to high impedance input when used, such as Lingyang, AVR, and so on. High resistance input can be considered as having infinite input resistance, indicating that I/O has minimal impact on the preceding stage and does not generate current (without attenuation), and to some extent, it also increases the chip”s resistance to voltage surges.
