Power monitoring solution, replacing PLC

Although just registered, let me complete this task.

To put it simply, our company's ** software FieldMonitor is referred to as FM.

To be honest, it refers to the advantages of ifix and intouch and integrates most of the domestic standard and non-standard protocols.

That is to say, as long as the power meter, whether it is IEC103 or MODBUS, is connected to the serial port of the computer, this software can collect it.

Don't let me write**You can send me an internal message.

Data acquisition and communication, row database configuration, screen production and dynamic display, server redundancy options, alarm recording and response (support mobile phone SMS alarm), ODBC database connection, process variables and database fields correspond, data storage and reading and writing, and realize seamless interface with crystal reports, historical reports, real-time reports, row printing reports, recipe applications, data batch management, Serial communication server (**dial, GPRS, CDMA, Serial port direct connection), support CDMA, broadband remote data, image monitoring, system information recording all operation information and system event information, user management, to achieve operation level differentiation, network server, implement client server structure, support secondary development, support remote real-time and historical data access (GPRS, CDMA, BROADBAND, ADSL), built-in vbscript script, support screen and global script, historical data storage and data analysis, support OPC server and client, Plant-wide data integration and processing packages.

To sum up, it supports most manufacturers' PLC products. It supports the functions of most of the commonly used host computer monitoring software.

I can send you a trial version, use it and find me.

It depends on how many points you monitor, if the amount of data is not very large, you can directly use the touch screen to establish communication with the instrument through modbus, and you can communicate in real time. In this way, the purpose of communication can be achieved.

If you have a large amount of data, you may need configuration software.

You don't need a PLC, I've done a good job of configuration, it's quite convenient, but I don't know how many sets of power meters you have to communicate, but it shouldn't be difficult.

It's simple, do you pay for it, I'll do it for you.

The security protection of the power monitoring system is to strengthen the information security management of the power monitoring system and prevent hackers and malicious attacks and infringements on the power monitoring systemThe regulations formulated to ensure the safe and stable operation of the power system were deliberated and adopted by the Office of the Director of the National Development and Reform Commission, and promulgated by Order No. 14 of the National Development and Reform Commission of the People's Republic of China on August 1, 2014, and came into force on September 1, 2014.

Power monitoring. With the development of power production technology and management level, higher requirements are put forward for the security protection of power monitoring systems, and the relevant management regulations and technical measures need to be improved and strengthened accordingly, which is mainly reflected in the following two aspects: First, at the technical level, with the rapid development and application of new technologies such as distributed energy, distribution network automation, and smart grids, the use of wireless public networks for data communication by power monitoring systems is becoming more and more common, and corresponding security protection measures need to be formulated;

The Stuxnet worm attack on the Bushehr nuclear power plant in Iran reflects the need to further strengthen the safety management of the power industrial control system and equipment in the production control area. Practical problems reflected in work practice on the protective measures for remote maintenance of equipment, the safety protection measures of intelligent substations, and the longitudinal boundary protection strength of non-controlled areas also need to be further clarified and standardized.

The complete set of solutions provided by Shanghai Juren Electric Power, the power monitoring system mainly realizes the close integration of relay protection and other equipment and integrated automation and networking, which is reflected in integration and resource sharing, remote control and information sharing. With the remote terminal unit and microcomputer protection device as the core, the control, signal, measurement, billing and other circuits of the power terminal are incorporated into the power intelligent information integration and data server system, forming a complete set of networked and intelligent hollowing out power equipment, and upgrading the traditional equipment and devices will effectively improve the technical level and level of power equipment and improve the performance of the power system.

Principles to be observed by power monitoring system manufacturers when designing systems.

Advancement. Make full use of computer network technology and advanced communication and control methods to establish a set of coal mine power monitoring system with advanced technology, complete functions and simple management. The system has a variety of communication interfaces in advance, and fully considers the expansion and compatibility of the system.

Change the previous substation to adopt the mode of PLC or single-chip microcomputer, and use the monitoring station embedded in the Congzhou computer, which can not only realize the data collection and function, but also realize the local display of data and rich operation functions, and can flexibly change the embedded computer built-in software according to the actual situation of the site.

Practicability. To meet the business needs of users, it has the functions of monitoring information collection, processing, investigation, infiltration, investigation, analysis, etc., and realizes the remote monitoring of the coal mine power supply system and the automation of underground substations. The system can be operated independently or seamlessly connected to the whole mine integrated automation platform system, and can realize the remote browsing function of power supply system automation through the web mode.

Reliability. Strict control in hardware design, selection, production process and process, etc., fully consider all factors in the construction of software environment and application system to ensure the high reliability of the system in special environments, and the power monitoring station itself has a rear power supply, which can ensure the normal transmission of data for 4 hours in the case of power failure.

Economical. On the basis of considering the supplier's credibility and maintenance service capabilities, the selection and configuration of the equipment follows the principle of optimal performance, and the system is designed to consider future upgrades and expansions, so that the cost of later maintenance and upgrading is very low.

Scalability. Reserve hardware and software interface resources for the expansion of the power system in the future, and only need to add low-level equipment and software settings when increasing the monitoring of the substation in the future.

The power monitoring system is generally 3 levels.

2. Communication layer: gateway line, mainly used to transmit the data collected by the instrument to the system platform through wiring or wireless mode;

3. Acquisition layer: intelligent instruments, mainly through intelligent electric sparrow lead attitude meter, intelligent water meter, steam meter, thermal energy meter and other instruments with communication functions for energy data collection.

PLC is a programmable logic controller, which is generally programmed with a ladder diagram to realize the logic control of local IO.

PLC remote monitoring I have used the solution of Detu information, but you can remotely read and write the PLC register through the mobile phone or PC web page.

To put it simply, a PLC is a CPU with an integrated block or microprocessor. However, the PLC is empty inside, and the integrated block CPU is different from the integrated block and the CPU is that the manufacturer has set up and programmed the application inside it, as long as it is directly assembled on the circuit board, it can work directly through the peripheral components on the circuit board and power-on, and various functions of the integrated block and CPU can be realized. But the only drawback is that its program function application is fixed and cannot be changed.

When the PLC is purchased, the internal content is empty, and we need to add the application to the PLC to implement the external demand function. You can also write a program, you can clear a program, or you can modify the program after writing a program.

The remote monitoring of PLC is generally achieved through Ethernet, and is realized by 4G mobile communication, such as the 4G gateway.

Power line network technology, abbreviated as PLC, refers to a communication method that uses power lines to transmit high-frequency data and voice signals. The modem of the power line network is referred to as "power cat", which is plugged into the user's computer at one end, and the other end is plugged into any of the popular power outlets at home, which can achieve a transmission rate of up to 200 Mbps or 500 Mbps, so as to achieve Internet access, channel reception, and video play.

For the future, power line network technology will face dual considerations of technology and market, due to the interference caused by voltage changes affecting the quality of the Internet, the number of electricity consumption during peak periods fluctuates greatly, PLC chips are mainly from Europe and the United States, and national laws and regulations are not clear, etc., will seriously restrict the benign development of power line network technology, and its future road to friends to return to travel is by no means smooth sailing.

SCADA (supervisory control and data acquisition) system, that is, data acquisition and monitoring and control system. The SCADA system is a computer-based DCS and power automation monitoring system.

DCS is the English abbreviation of distributed control system, which is also called distributed control system in the domestic automatic control industry. It is a new type of computer control system relative to the centralized control system, which is developed and evolved on the basis of the centralized control system.

PLC is the abbreviation of programmable logic controller, which is mainly used to realize the control of on-site switching and the acquisition of analog quantity.

So obviously, SCADA is the largest, with DCS underneath, and PLC is their front-end action executor.

Plate B belongs to the electrical application sector, which is divided into: B0 (Siemens series PLC) B2 (Schneider series PLC) B3 (A-B series PLC) B4 (automation system related knowledge) B5 (industrial instrumentation related) B6 (low-voltage electrical part) B8 (medium and high voltage electrical part) B9 (electrical automation other).
