Qualification improvement, scheduling industry leading brands. Get Changzhou mine communications monitoring equipment testing centers issued proof certificate (CCCMT12.0483) safety standard national mining product safety mark issued by the Centre of mining product safety certification mark (MHC130012) and a number of patents. Heng Communications is a leading manufacturer of dispatch equipment, set up in China's major coal resources in Pingdingshan city, is a research, production, sales and service as one of the national high-tech enterprises, products widely used in coal, electricity, metallurgy, oil , mining, chemical, railway, aerospace, transportation, public security, military and other fields, to leading technology to provide our customers with complete system solutions. KTJ119 type mine general and Intrinsically Safe scheduling system is the company through long-term market surveys carried out multiple visits, research and feasibility studies, at home and abroad on the basis of merit scheduler on the use of computer software technology, electronic communications and network technology , the world's most advanced level of production testing process, in strict accordance with the International Telecommunication Union (ITU-TG.712, No. G.713), the relevant provisions of "coal mine production safety rules" and the latest standards of China's telecommunications industry, according to the actual coal mine demand, followed reliability, advanced, stability and usability principles, design and development of a new generation of digital program scheduling system has completely independent intellectual property rights. System features: 1. hot-swappable, mixed into hot backup 2. Board 3. The secondary power supply hot backup unit board failure detection and automatic isolation 5. relay circuitous routing, redundancy 6. Low power consumption 7. Upgrade 8. 9. Scalable strong user interface and a communication port 10. All K20 lightning fast boot time for 3-5 seconds 11. All board work status alarm indicates the maximum number of gates Extension: 64-1792 door Maximum Relay Door Number: 16-1024 Door Advantages: (1) High reliability: the host control system and power system hot backup, system parameters and never lost, the system has automatic fault detection, fault seamless switching, absolutely avoid the system crash. All card have hot plug technology, installation and maintenance are very convenient; all interfaces with overvoltage, overcurrent protection; and anti-lightning through K20 test, with three lightning protection, fully able to meet heavy minefield Special environmental requirements. (2) advanced technology: the introduction of the world's leading technology and automated patch welding wave soldering machine, achieve world-class level. Philips microprocessor hardware and National Semiconductor Corporation, plus the big Mitel communications ASIC VLSI, advanced machine technology, high integration, CPU board uses advanced chip technology, equipped with DSP, FPGA, ASIC, CPU and other ultra-large-scale chip, has the ability to handle high-speed data. (3) designed: a unique combination of centralized and dispersed control, self-contained modules, are using separate sub-board control, board and module directly using PCM bus for communication, information transfer and high reliability user interference ability to improve the overall reliability. Non-blocking switching network system design, capacity: 1024 * 1024 or 2048 * 2048 and other specifications, to ensure the system call, the call, the dispatcher never busy, absolutely smooth. (4) Advanced DSP technology: scheduling conferences using DSP chip technology with independent intellectual property rights, clear sound, set flexible. Support inside and outside the line multi-party conference call. (5) intelligent and reliable power supply: dedicated communication switching power supply. -48V DC can be directly connected with the bottle, in the normal state of the battery-powered automatic charge, will automatically switch the power outage, the battery-powered, ensure that the entire communication network without interrupting the operation. Interfaces with intelligent charging, over-voltage, over current, lightning protection. This system is in addition to the above features, it also has a relay alternate routes, redundant backup; low power consumption, scalable, extensible; faster boot time (3-5 seconds); all the cards work status alarm notification; support DTMF, FSK two modes for audio reception and transmission formats, cut bell design, relay traffic balanced distribution, voice mail and billing system built, permanent storage bill and so on. My company mainly produces all kinds of mining machine scheduling, mine scheduling machine, telephone scheduling machine, coal mine scheduling machine, program scheduling, digital program-controlled scheduling, program-controlled switches scheduling, dispatch scheduling program-controlled switches and other equipment used.
