COMMUNICATION SCHEME FOR COAL MINE INTEGRATED SCHEDULING

BACKGROUND OF THE PLAN:

The coal mine scheduling communication system is an important component of coal mine safety production. The advanced production scheduling command system ensures fast and accurate information transmission through diverse means, ensuring coal mine production safety.

SOLUTION:

The intrinsically safe program-controlled scheduling machine and touch screen scheduling console for mining use have rich integrated scheduling functions, supporting administrative scheduling integration, enabling one click scheduling, direct telephone, group call, group answer, group call, full call, multi-party call, forced insertion, forced disconnection, monitoring, recording and other functions. They can also achieve interconnection and coordination with gas alarm, video surveillance, personnel positioning and other systems to improve production management efficiency.

PRINCIPLES OF SCHEME DESIGN

1. Meet the safety and production needs of both above and below the well

Coal production is mainly carried out underground, with harsh working environments (small working areas, poor lighting, humidity, and corrosiveness), multiple unsafe factors (mainly the threat of water, fire, gas, roof accidents, etc.), and high personnel and equipment mobility, among many other special factors. From the perspective of the operation process, there is also a characteristic of multi job joint flow operation underground. This type of operation often involves many heavy equipment, and the transportation, installation, and commissioning coordination between equipment require high requirements. Information transmission must be timely and accurate. At the same time, the management department and production auxiliary links of coal mine ground have all the characteristics of ground factory production. So the coal mine communication network must meet both the safety and production needs underground, as well as the needs of surface production, command, management, and people's lives.

In the design of the coal mine communication network, the principle of one-time planning, step-by-step implementation, and long-term benefits should be followed. Fully utilizing advanced and comprehensive digital scheduling equipment configuration, with a flexible and reliable network structure, to create a modern intelligent coal communication network that can meet the short-term and long-term needs of coal production scheduling and command.

2. A highly reliable production scheduling communication system serves as a guarantee

Most mining group companies rely on factors such as multiple mining sites and long distances between mines. Therefore, it is required that the coal private network dispatch communication should fully utilize the concept of integrated network and adopt an integrated network communication platform. In addition to establishing an administrative communication system and a general dispatch command center, it is also necessary to establish production dispatch communication systems for the first and second mines, each equipped with digital programmable dispatch machines. The general dispatch command center can centrally dispatch and manage the subordinate mine dispatch command centers, enabling the general dispatch personnel to establish contact with any telephone in any communication system at any time through the dispatch console, achieving the requirements of speed, convenience, and one click access. It is possible to establish contact with higher-level dispatchers at any time and form a network with each other. The telephones in each mining area can be dialed equally to meet the needs of modern and advanced coal mining production scheduling and command.

3. Effectively ensuring the reliable operation of equipment

With the continuous improvement of modernization in coal production, the requirements for communication methods and system functions are also increasing. Ensuring timely, accurate, and rapid transmission of communication information is extremely important for coal production and operation. The construction of the system requires the integration of wireless communication and several scheduling programmable scheduling machines to form an integrated scheduling communication network structure; It is necessary to have independent and comprehensive hardware and software measures to detect faults. Once a fault occurs, it should automatically isolate and perform location diagnosis. There should be technologies such as primary and backup redundancy, decentralized control, software fault tolerance, etc., which can independently survive and be clearly separated in terms of structure, function, business, and equipment management to effectively ensure the reliable operation of equipment.

COMPOSITION OF MINING INTEGRATED SCHEDULING SYSTEM：

1. Scheduling host: The scheduling host should implement all call functions, switching functions, scheduling functions, multi system linkage, and networking functions, and can adopt different configurations according to user needs.

2. Dispatch console: The dispatch console is a platform for carrying out specific operations. Dispatchers can observe the usage status of all dispatch users through the dispatch console and perform dispatch operations. The dispatch station sets buttons to correspond with the called number, enabling one click calling from the dispatch station.

3. PC terminal maintenance: The role of terminal maintenance is to control and maintain the work of the digital scheduling host, including data management, maintenance, conference call management, and billing management functions.

4. Full channel recording system: Record any communication line in the entire system.

5. Dispatch machine wiring system: composed of mining communication cable MHYV, mining cable distribution box, explosion-proof telephone junction box, etc.

6. Main products for host matching (optional): mining telephone coupler, mining communication cable, communication line comprehensive protector, intrinsic safety explosion-proof telephone.
