With the advent of the era of knowledge economy and network economy, intelligent housing has become the fundamental guarantee for a new lifestyle in the new century. With the rapid advancement of social informatization, people’s attention to housing is no longer limited to room area, surrounding environment, transportation, etc., but more interest and attention are placed on communication with the outside world, information services, and safety precautions. , Property management, etc. This requires traditional residential communities to adopt advanced technology to extend their service functions.
CONEXTOP(
www.conextop.com
) Is a German-based supplier of equipment networking products and solutions, with more than 10 years of experience in equipment networking product development. The NePort series is a highly integrated, high-performance RJ45 product for embedded device networking servers released by CONEXTOP in early 2002. It provides customers with a set of simple, high-performance and low-cost network connections in a small size. By using it, any device with a standard serial port can be easily connected to the Ethernet. NePort has a 10M/100M Ethernet interface, and can transmit TCP/UDP packets to multiple data receiving devices at the same time. And provide 1-2 high-speed serial ports, the baud rate can be as high as 921600bps. Lingchuang Technology (www.creativetop.com) cooperates with Conextop of Germany, and promotes and sells its serial server products and products for conextop in the country. With modules and network single chips, conextop has a global market share of hundreds of thousands of serial networking devices, and is one of the most established manufacturers of device networking and data center management technology. Since its establishment in 2001, Lingchuang Technology has been committed to the development of embedded products and providing effective solutions. Through 7 years of experience, he has guided the technological development and technological innovation of the industry, and has made some immeasurable progress. Through the cooperation relationship with conextop, we are looking forward to working with you to make the whole market next. The peaceful age brings more powerful solutions.
This system is mainly an intelligent community solution based on the existing Ethernet. The whole system includes the following systems: residential monitoring system, emergency alarm system, automatic meter reading and access control system, network office system, telephone system, broadband network system, network service system, etc. The key to this system is how to effectively process the access control and three-meter automatic reading data directly uploaded to the management center of the community, which can make full use of the German conextop company (
www.conextop.com
) Serial server serial networking module plus some serial devices such as 232, 485 access control, smoke alarm, remote electric water meter, etc., and through the broadband network system of the community, so as to realize the centralized monitoring and management of data, and achieve the maximum configuration of manpower and material resources. .
Serial server serial to Ethernet module mainly completes the conversion of Ethernet TCP/IP protocol and measurement and control equipment fieldbus RS-232, RS-485, RS-422 and other protocols at the network layer, and completes the interconnection between Ethernet and fieldbus networks. Realize data exchange between different Ethernet and fieldbus networks. In this smart community, the existing network and conextop’s serial server serial port to Ethernet module are used to organically integrate various serial port subsystems in the community. Using Neport’s TCP/IP Server/Client’s intelligent residential community control technology based on Ethernet communication means, it can integrate residential building anti-theft alarm, disaster alarm, emergency help, remote automatic transmission of water and electricity three meters, access control system, household appliances control , Electronic bulletin and other functions in one, centralized management and control system through the broadband network system of the community.
As a transparent data transmission terminal, Neport can be added with a conversion IC to make a plug-in serial server, which is connected to the central control computer through the community broadband line network; the central control computer can monitor and manage each Neport serial server and use the database Save the relevant data of the household. It can also be embedded in some serial communication devices such as access control machines, time attendance machines, smoke alarms, etc. in the form of modules, so that the original serial devices can directly communicate in the form of network ports, and the central control computer has networking functions for these devices. Access control machines, attendance machines, smoke alarms, etc. are monitored and managed to achieve unified management of data.
The network communication interface is responsible for processing the network transmission protocol. The data packets input from the network are processed with all protocol headers, and reassembled into complete application layer data in the buffer, and sent to the intelligent control unit through the asynchronous communication port. The data sent from intelligent units such as intelligent anti-theft alarm, disaster alarm, emergency help, water and electricity multi-meter remote automatic reading, access control system, household appliance control, etc. are packaged in the communication interface unit and added to the protocol header to a host on the network or For multiple hosts, the media access protocol is Ethernet IEEE802.3, and the network transmission protocol uses TCP/IP or UDP/IP.
Application software is divided into management system software, alarm monitoring system software and so on. On the basis of no need to change the original software used in serial communication, the virtual serial port software developed by conextop company based on serial server serial port to Ethernet module serial port networking can realize gas leak alarm, fire alarm system, emergency help system, Remote meter reading system, data management, equipment control, access control system and other functions.
For outdoor community entrance and exit control, install the IC machine at the entrance of the community. These IC machines can be converted by embedding Neport serial port to Ethernet module before leaving the factory to become a network-type TCP/IP access control machine, or through a plug-in based on Neport module The serial port server is connected to the Internet. Residents in the community can enter and exit with their IC cards. If the IC card is lost, report the loss immediately and cancel the card information. Visitors must register for entry and exit. The structure is relatively simple, which will greatly simplify the difficulty of construction and system maintenance. Security: A TCP point-to-point connection is used between the device and the network management system, and the device does not receive any data packets from the IP address of the non-network management system.
