chrispeng [ad_1]
As an important part of the mine information and communication system, the mine wireless communication system is playing an increasingly important role in modern large and medium-sized mining enterprises. The mine wireless communication system has the functions of communication (voice communication, digital packet communication), dispatch (telephone dispatch, meeting tandem), control and information collection, etc., and is used in mine production dispatch, command and unit internal communication. At the same time, with the continuous improvement of the automation level of mining enterprises, the requirements for communication equipment are getting higher and higher, and the development of wired communication to mixed communication with/without has become a general trend.
Using TD-SCDMA technology to provide 3G data services
Datang Telecom promotes the development of the Internet of Things industry through its own advantages in TD networks, chip design and manufacturing, terminal applications, and information security, and assists customers in actively exploring business applications in new environments. Through the effective combination of TD technology, perception layer technology and new applications, and the unique high spectrum utilization and large capacity of TD-SCDMA, it will fully satisfy the interconnection of things and things in mining enterprises, and the industrialization and informatization of mining production. Combine.
Regarding the application layer, network layer and sensor layer involved in the Internet of Things industry, Datang Telecom has accumulated strong technical reserves in the fields of ID, GSM industrial modules, 3G terminal modules, 3G industrial modules, TD network terminal equipment, and wireless broadband. At present, it provides sensing layer chips and modules for IoT applications, network layer wireless mobile communication end-to-end solutions, and application layer industry application software.
According to the actual requirements of users, the KT151 mine wireless communication system independently developed by Datang Telecom adopts the 3G mobile technology of my country’s independent intellectual property rights-TD-SCDMA technology to form a private underground wireless network to realize mobile communication above and below the mine. In addition to providing traditional voice, short message and other services, it can also provide 3G services such as videophone, video surveillance, broadband data access, and at the same time realize unified number management, integrated dispatch and unified management of wired and wireless communication networks through intelligent dispatch switches Network management can not only meet the needs of single mine wireless communication applications, but also meet the needs of large mining groups for multi-mine network roaming. It can provide users in the mining industry with overall solutions and improve the management level and production efficiency of enterprises.
Multi-service integration of communication platform
Adopt the KT151 mine wireless communication system based on my country’s independent intellectual property rights and advanced 3G mobile technology standards to form a wireless mobile private network in the mining area to realize mobile communication above and below the mine, and realize wired and wireless integrated dispatching through integrated intelligent dispatching switches Features. Its core equipment, SP30-AVS switching dispatcher, integrates various TDM, VoIP and mobile advanced technologies in the communication field, and relies on the company’s existing Intranet network to build a multi-service integrated communication platform for the company. This system adopts advanced software and hardware technology and telecommunication-level design to ensure the high reliability of the equipment.
On the user side, SP30-AVS provides wired, wireless, and packet integrated access methods. The wireless communication system adopts the TD-SCDMA mode to form an underground wireless mine private network to realize underground mobile communication and 3G data services. The communication network has the following functions: the establishment of a private network for the underground TD-SCDMA wireless communication system in the mine area to realize underground mobile communication; realize the short message service between mobile phone users; provide 3G data services on the basis of the voice service; the system network side provides multiple A kind of interface, which can be connected to the circuit-switched network through E1 digital relay or COTK analog relay, and the digital relay signaling method supports No.7/PRA; it is connected to the data network through an IP interface; it can realize wired and wireless unified number management, Integrated scheduling and unified management.
