Protocol, it belongs to a kind of communication protocol used by distributed control systems for underlying communication. Well, it is a communication protocol and plays a relatively important role in the field of automation control. This agreement is a product produced by Eschenbach, the United States. Anyway, it is a technology they proposed to achieve interoperability between devices and conduct reliable communication, that is, reliable operation, message transmission between devices, transmission of control signals, etc., which are the uses.
If we need to figure out the agreement, we actually need to do a lot of things with many key elements. The first point is chip.
This chip is a very core component or component product in the protocol. Simply put, the chip is regarded as this set of chips, which is the core device. It just needs to understand what the role is like the commander, and it can control and maintain the basic operations of the equipment, etc. Basic operations are relatively normal calculations and control the operation of the equipment. It has three built-in 8-bit CPUs, which handle different transactions and there are three CPUs. Some CPUs are doing communication control work, such as communicating with other chips to do control and convey relevant messages, some specialize in data processing at the MAC (media access control layer) layer, and there is also a managed application, such as calling and querying on the application side
The second point is the communication medium.
The protocol can use a variety of communication media for communication and communication work. Commonly, twisted pair cables are used the most, and wired transmission is common. Why? Because it is convenient to wiring, the requirements for laying are not that difficult. It is used in very common scenarios, many scenarios can be used, many, whether it is a simple office or a complex park environment, industrial control site environment, etc., and many environments, basically, they may encounter laying situations, and they are used a lot, and signal transmission has such reliability and advantages. Wired is very good and reliable. In addition, radio, optical fiber and power lines can all be used. These are used as Lon-Works media, which can make wiring convenient or overcome the weaknesses of special areas (special examples such as optical fibers for complex electromagnetic areas, etc.).
There is also the key point.
This protocol has a standard application framework based on the application framework. This set of situations is constructed on the seventh level of the ISO/OSI communication model. The application can be regarded as a broad classification. Here, it provides infrastructure support for the realization of interoperability between devices and other devices and provides a similar support structure concept. Based on this, various specific applications can be operated according to the rules framework, so that multiple devices can communicate well under the same information architecture rules, so that communication is much more convenient and convenient.
Let’s explain this through a little bit of Q&A.
Some friends would like to ask, for example, why is the protocol used in the same direction and scope? What are the advantages of protocol communication? Speaking of Hachi's unique protocol, it contains the physical layer, MAC layer, and network layer communication standards, and has strong anti-interference performance and is very powerful. For example, in an industrial environment, if other messy signals are interfering with each other, this protocol guides the device to transmit on twisted pair to ensure that the data is stable, ensuring that the signal is not easily distorted or lost, etc. are rarely happening. Other protocols without similar mechanisms may be easily interfered by external interference and cause some errors. And some protocols that extend the gender of communication media are not as rich as that.
For example, what industry scenarios are most suitable for using agreements! Well, in many scenarios such as smart home and smart building, such as the lighting of the hotel automatic system and the unified allocation and control between various equipment, its distributed control characteristics can be greatly utilized and used to achieve good results. In commercial buildings, ventilation equipment coordinates and uniformly commands and adjusts temperature. This purpose is to coordinate indoors, and the overall adjustment of comfortable air conditioning and ventilation is also good. In addition, industrial factory control equipment production rhythm and process are also widely used in this type of production, so that the equipment can work through the agreement in an orderly manner and exert corresponding performance. In fact, many environments involve distributed and require the control, adjustment and monitoring of these demand-type equipment scenarios.
In terms of energy optimization, many buildings or factories need to calculate the energy consumption of equipment, etc. to improve the situation. Using protocols, you can use chips and other equipment to accurately obtain a lot of data, unit values, etc. energy consumption, and pass it to the upper energy monitoring system for specific analysis. For example, which machine tools consume electricity last month to calculate the amount, conduct energy efficiency analysis and compare similar factories to make corresponding strategies and adjust the situation. This is a very typical example. Data communication and analysis are used to achieve subsequent adjustment purposes. This is a very beneficial situation to achieve the purpose of energy saving and optimization, save costs for enterprises and make control more effective and reliable, and the application is quite widespread, and the results can be seen everywhere. These are very good in terms of wide application. Provide global procurement services for weak current intelligent products! Moreover, with the continuous development of the industry, I think it will definitely expand and explore the update scenarios and existing basic scenarios, and will develop and grow and improve a lot. Give full play to better serve in various industries and industries, and there will be technological innovations and continuous improvements as technology continues.
