For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, detailed descriptions of well-known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic diagram showing a configuration of a wireless cornering control system using a BCM according to the present invention.

Referring to FIG. 2, the present invention includes several chambers 110 installed in each of the chambers, an angle valve controller 120 for receiving signals from the main chambers and adjusting the opening amount of each valve, A main room controller 100 for receiving data on the current state of the valve controller 120 and storing and displaying the data and controlling the respective valve controllers 120 and the room controllers 110, And a BCM (Boiler Control Module) 130 connected by a PLC (Power Line Communication) and transmitting a control signal of the main room controller to the boiler 140.

The main room controller 100 includes a wireless communication unit 102 for communicating with the cubic valve controller 120 and the room controllers 110 and a PLC communication unit 101 for communicating with the BCM 130, 140 and the microcomputer 103 for data processing required for controlling the respective valves 122. It also includes a display unit and a key input unit 104 for the user.

Particularly, since the main room controller 100 receives power from the BCM 130, it is not necessary to provide a separate power source, and the system can be controlled stably even when a large current is consumed.

The cubic valve controller 120 controls a driver to adjust the opening amount of each valve in response to a control signal from the main room controller 100 and has a wireless communication unit for wireless communication with the main room controller 100.

The room heaters 110 are installed in the respective rooms to control heating of each room according to a user's operation and are provided with a wireless communication unit 111 for communicating with the main room cone 100. The power source unit 112 Battery type.

The BCM 130 includes a first communication unit 131 of a power line communication system for communicating with the main room 100 and a second communication unit 132 for communicating with the boiler .

In general, the boiler or the cubic control system uses a communication protocol unique to each manufacturer. The second communication unit 132 employs a communication protocol of the same standard as the communication protocol used in a boiler of any kind, RS-485 communication protocol is adopted, and communication is possible even when communication protocols are different.

In particular, when the communication protocols of the boiler are different, the second communication unit performs mutual communication between the boiler and the BCM through the general-purpose RS-485 communication module. Recognize the communication protocol of the boiler based on the preset values preset in the BCM using the DIP switch built into the BCM or the automatic recognition method. As an example of a communication method for controlling the boiler in the communication protocol, a method of changing the contact value to the A contact or the B contact according to the state of the contact of the boiler may be applied.

The BCM 130 may be connected between the boiler 140 and the main room 100 or may be connected to the main room 100 as a separate unit.

3 is a flowchart illustrating a time division transmission and reception method applied to wireless communication between a main room controller and a room controller according to the present invention.

Referring to FIG. 3, in the wireless communication between the main room controller 100 and the room controller 110, each room controller 110 is assigned a unique ID, and transmission / reception intervals are separately set for the respective IDs. Thereafter, it wakes up according to its own cycle, attempts wireless communication with the main room controller 100, receives an ACK signal from the main room controller 100, or switches to the sleep mode when its cycle ends.

By using such a transmission / reception system, it is possible to prevent a communication failure that may occur due to simultaneous transmission of data, and to reduce wake-up time of each room controller 110, thereby reducing unnecessary battery consumption.

In the meantime, the room-specific room controller 100 and the main room controller 110 minimize the data transmission error that may occur in the wireless communication by using the retry transmission / reception system that transmits the transmission packet five times during wireless communication.

When the battery remaining amount falls below a predetermined value, the battery replacement message is turned on so that the user can easily know the battery replacement time, and the main room con- When the communication state of each room controller 110 is periodically checked and communication is disabled for 240 seconds or more, a function of forcibly turning on / off the valve actuator of the room is activated in the main room controller.

It will be apparent to those skilled in the art that various modifications and equivalent arrangements may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
