Description

Standard protocol based boiler and water heater cascade integrated remote management system and method

The present invention relates to a standard protocol-based boiler and water heater cascade integrated remote management system and method, and more particularly, to a standard protocol-based boiler and water heater for parallel and remote control of a cascade device comprising a series of units Cascade integrated remote management system and method thereof.

In general, the boiler industry is applying small boilers or small water heaters in parallel to the medium and large boiler / water heater market. Such a system that connects small boiler / water heaters in parallel is called a cascade system.

Cascade system advantages can be classified into three major categories.

First, cascaded systems can be used to build energy-saving systems.

Medium boilers / water heaters are less than 90% efficient, while small home boilers / water heaters guarantee high efficiency of at least 95% and up to 98%.

In addition, the medium boiler / water heater is operated on / off in the partial load operation, while the domestic boiler / water heater is capable of partial load operation from the minimum of 10% to the maximum of 100%.

Second, the cascade system is economical in the reduction and maintenance of the installation space.

In other words, in order to install a medium boiler / water heater, it is necessary to secure a space for maintenance in all directions, while the Cascade system uses a small boiler / water heater for home use, so it is possible to install a wall, so there is no need for a separate maintenance space. In addition, if the boiler / water heater is oversized, the statutory safety manager must be appointed as mandatory.However, the cascade system is constructed by connecting several small households, so it is not necessary to select a separate statutory safety manager. It's a system.

Third, the cascade system can be used to build a non-stop system.

In other words, if a failure occurs in any part of the medium boiler / water heater system, there is a case in which a redundant facility is constructed to prevent the operation of the building itself. However, Cascade system is composed of several small boiler / water heaters in parallel structure, so even if one breaks down, other equipment is running, so 100% output is impossible, but some parts can be operated. There is an advantage to build a system that can not be.

As described above, although there are various advantages of the cascade system, there are some problems to be solved in order to use a domestic boiler / water heater in an industrial facility.

In industrial facilities, all facilities are linked to the central control server, so the information and setting values of the domestic boiler / water heater should be transmitted to the central control server.

Since the industrial central control server is constructed as a standard protocol based system, the small boiler / water heater must support the standard protocol to transmit information to the central monitoring board.

In addition, since several small boiler / water heaters are connected, it is impossible to find a failure even if the manager does not look closely.

In addition, in order to apply a small boiler / water heater to a medium-sized system, additional automatic control and facility piping such as a separate circulation pump, a temperature sensor, and a pressure sensor must be added, and an automatic control device is also required.

On the other hand, medium-sized boilers / water heaters are used to build heating and hot water systems in buildings at home and abroad, but nowadays, small boilers / water heaters are bundled into one group to replace medium boilers / water heater systems for energy saving and space reduction. Cascade system is applied.

In other words, several household boilers / water heaters are configured in parallel and applied to industrial use.

In order to apply the domestic boiler / water heater to the industrial, the central control system should be able to check the status value of the boiler / water heater in real time for the safety of the system.

However, communication protocols used in small boiler / water heater are different from company to company, so it is not possible to link with standard protocol based central control system, so it is simply composed of start / stop by contact point, and status information has pipe or tank temperature. Check the normal operation of the boiler / water heater.

In addition, a manager is separately designated for each building, and the manager judges the driving status and abnormality. The management system by such manpower may have an error determination due to the error of the manager and there is a problem that is not economical because additional manager cost is required.

In addition, if an error occurs in the boiler / water heater, the AS time is long because the manager receives the AS, which is a direct cause of the prolongation of equipment downtime.

In order to solve the above problems, the present invention installs a standard protocol-based integrated controller in a boiler / water heater Cascade system, converts all the data of the boiler / water heater of a non-standard protocol into a standard protocol, and provides a centralized control server and an integrated remote management server.
