WIRE WATER SUPPLY VALVE OPENING AND SHUTTING TYPE WIRELESS CONTROL SYSTEM IN HEATING APPARATUS AND THE CONTROLLING METHOD THEREOF}

The present invention relates to a wireless control system and control method for opening and closing a hot water supply valve in a heating system, and more particularly, transmission data according to a comparison between a set temperature in each heating zone and a current room temperature, and a temperature controller installed in the heating zone.

In general, the heating method for residential and office spaces, such as apartments or offices, is divided into central heating or individual heating depending on whether a valve for opening and closing a hot water supply valve is provided for each heating zone. The piping diagram is shown in FIG.

That is, as shown therein is connected to the outlet of the boiler 10, the boiler 10 for circulating the heating water obtained by generating the heat energy required for heating and heating the storage water therein to the indoor side to circulate the heating water Each heating is performed by the inlet distribution valve (or hot water supply valve) 14 and the heating water provided by the inlet distribution valve 14 which adjust the outlet pipe 12 and its outlet pipe 12 to regulate the amount of heating water. It consists of a heating pipe 16 piped in the heating zone to heat the zone, a discharge distribution valve 20 and a discharge pipe 18 for discharging the circulating water (heating water) circulated through the heating pipe 16 to the boiler. Here, the temperature controller 17 is installed in each heating zone (A1, A2, A3), but only one may be installed as a whole.

Here, in describing the present invention, the same parts as in the prior art will be omitted.

As shown in the drawing, after comparing the set temperature in the heating zone with the room temperature, the temperature controller 100 for wireless output by adding a device identification code to the transmission data for controlling the corresponding hot water supply valve 14, Independently installed in the heating zones A1, A2, A3, the valve control device 200 for receiving the transmission data and controlling the hot water supply valve 14 corresponding to the device identification code is installed in the heating hot water valve portion. It is composed.

The temperature control device 100 is a temperature detector 102 equipped with a temperature sensor to detect the room temperature in the heating zone (A1, A2, A3) and a temperature setting unit (temperature controller) for setting the optimum temperature in the heating zone. 104, each of the A / D conversion unit 106 and the A / D conversion unit for digitally converting the temperature data detected by the temperature detection unit 102 and the temperature setting unit 104 and the predetermined temperature data. A transmission control unit for outputting transmission data to which a device identification code assigned to each temperature controller 104 is added in order to control the corresponding hot water supply valve 14 according to the comparison result of the detection data and the setting data applied from 106; 108, and a modulator / PLL unit (110, 112) for modulating the output transmission data, and transmits the transmission data via the transmission unit 114 with the carrier frequency.

In addition, the valve control apparatus 200 is configured to receive and demodulate the transmission data from the temperature control apparatus 100 according to the device identification code included in the receiver 202 and the demodulator 206 and the demodulated transmission data. The corresponding hot water supply valve 14 is composed of a reception control unit 208 for generating a control signal for driving the valve driving unit 214 to open and close.

Reference numeral 204 denotes a PLL unit for separating the carrier frequency from the transmission data, and 212 denotes an SCR for driving the valve drive unit 214 by the reception control unit 208.

The valve control apparatus 200 further includes a device identification code storage unit 210 that stores all the device identification codes of the temperature controller 100 independently installed in the heating zone.

The operation of the present invention configured as described above will be described with reference to the accompanying drawings.

First, the temperature controller 100 is installed in one or more heating zones A1, A2, A3, ..., and is disposed in an arbitrary heating zone according to temperature data provided from the plurality of temperature controllers 100. A valve control device 200 for controlling the opening and closing operation of the hot water supply valve 14 is provided at a predetermined position (preferably near the heating hot water valve).

Of course, since the temperature control device 100 is wirelessly connected to the valve control device 200, it can be arbitrarily mounted at an appropriate position in the heating zone.

At this time, each temperature control device 100 has a device identification code is built in each, valve control device 200 can be identified by the device identification code for all the temperature control device is stored in the device identification code storage unit 210. Will be.

In such a state, the room temperature in any heating zone (eg, A1) is set to, for example, 20 ° C. by operating the temperature controller 104, and then heating is started (steps 300 and 302). The digital conversion is applied to the transmission control unit 108, and the temperature detection unit 102 detects the room temperature at regular intervals or continuously, and the detected temperature is also digitally converted and then the transmission control unit 108 Is applied (step 304).

Then, the transmission control unit 108 compares the applied set temperature data and the detected temperature data and determines whether to heat the heating (step 306). If the current detection temperature data is smaller than the set temperature data (step 308 No), i.e., if it is detected below 20 ° C, heating can be continued (step 310), whereas if the detected temperature data is larger than the set temperature data (YES in step 308), i.e., if it exceeds 20 ° C In order to close the valve corresponding to the heating zone, the transmission control unit 108 adds and outputs a device identification code for identifying a thermostat to the transmission data (step 314).

The output data is transmitted through the transmitter 114 along with the carrier frequency generated by the PLL unit 112 after a series of modulation processes in the modulator 110.

The output data is amplified by the receiver 202 of the valve control apparatus 200 spaced a predetermined distance, and then demodulated to the original data by the demodulator 206 and applied to the receiver controller 208.

Then, the reception control unit 208 confirms that the transmission data is transmitted from the temperature controller installed in which heating zone, the device identification code storage unit 210 searches the same device identification code to confirm the temperature controller. . For example, when the device identification code of the temperature control device included in the transmission data and installed in the predetermined heating zone is '001', the reception control unit 208 receiving the device identification code is stored in the device identification code storage unit 210. The same device identification code is stored and the heating device is identified in which heating zone.

Then, the reception control unit 208 closes the corresponding hot water supply valve 14 by driving the valve driving unit 214 installed in the heating zone according to the device identification code and the control signal for closing the valve (step 316).

In such a process, when the corresponding hot water supply valve is closed, the heating hot water flowing to the heating pipe of the heating zone is blocked, thereby preventing the room temperature from rising any further.

On the other hand, when the detection temperature is lower than the set temperature or the hot water supply valve 14 is closed in accordance with the above-described process, the temperature detector 102 in the heating zone continues to detect the room temperature, and the detection result If the current room temperature falls below 20 ° C, the transmission control unit 108 transmits the temperature data together with the device identification code to the valve control unit 200, and opens the valve to supply the heated hot water again. .

Of course, when the heating stop command is applied, the heating is stopped regardless of the indoor temperature and the detected temperature in the heating zone (step 312).

According to the present invention, when the indoor temperature and the set temperature are output to the transmission control unit while the indoor temperature of each heating zone is adjusted differently, the transmission control unit together with the device identification code for identifying each heating zone. Transmission to the valve control device, the valve control device can wirelessly control the opening and closing operation of the valve corresponding to the heating zone.

As described above, according to the present invention can supply the heating hot water for each heating zone to maximize the heating effect as well as to minimize energy waste due to unnecessary heating, wireless between the temperature control device and the valve control device Since the frequency is used, the piping work for laying the wiring required for the conventional heating can be omitted, thereby saving work time and cost.

Moreover, since each of the temperature regulating device and the valve adjusting device is operated according to the device identification code, it is possible to prevent a malfunction in which another valve adjusting device is operated.

And because the temperature control device uses a power supply means such as a battery, it is possible to select the appropriate height and location according to the convection conditions and heating conditions in the heating zone, thereby maximizing the heating efficiency.
