According to Korean Patent Laid-Open Publication No. 10-2009-0072339 (Method for detecting the failure of opening and closing valves of a heating pipe of a boiler using an overheat protection function), "In a method of controlling operation of preventing overheating (boiling) of each known control system, a boiler is overheated And entering the anti-boiling operation mode, the microcomputer in the controller checks the number of rooms (i) having the heating mode "on" state among the several remote controllers and sets the number n of rooms to be checked having the initial "0" state. 1 "Incrementing step; Open all heating pipe shut-off valves installed in several heating pipes to dilute the heating water to a uniform temperature, and continue to operate the circulation pump of the boiler for a predetermined time, Circulating and diluting all heating pipes; and when the circulating pump is driven for a predetermined time and stopped, all other heating pipe shut-off valves are closed and “1” is incremented above. Performing only the combustion operation of the boiler by opening only the heating pipe open / close valve corresponding to the number of the inspection target rooms (n) determined by the TMS, and determining whether the heat exchanger tapping temperature of the boiler is lower than the reference superheat (boiling) temperature. And if the tapping temperature is higher than the reference value, the error is displayed on the display unit of the remote controller installed in the corresponding room. Determining whether the number of rooms to be checked (n) obtained as a result of the result is equal to the number (i) of the rooms in the heating mode " on " as a result of the determination, and the number of rooms to be checked up previously (n); ), And if it is not the same, return to the step of incrementing the number of rooms "n" to be checked by "1". If i = n, it is detected whether or not an error has occurred. If there is no room in which the error is detected as a result of the above detection, it is recognized as a failure of the boiler itself and the boiler check mark is displayed on the display of the controller. It is characterized in that it comprises a step of indicating to check, so that if the overheat protection error (or boiling error) of the boiler occurs, the boiler itself failure and each heating control valve opening valve or AIR PURGE failure of each room control system It can be displayed separately so that after-sales service (A / S) can be easily carried out, as well as greatly improving the merchandise and reliability of the boiler itself.

2 is a flow chart showing the operation flow of the heating piping system using a sensor according to the present invention.

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

1 is a block diagram showing the configuration of a heating piping system using a sensor according to the present invention, wherein the heating piping system is a supply pipe 16 for supplying hot water and a heating section heated by the supply pipe 16. Three blocks and a return tube 17 to warm and reheat the first to third blocks are provided.

In this case, the first to third blocks are for illustrative purposes and may vary depending on the heating area of the building, namely, the number of floors, or building characteristics, that is, apartments, officetels, and studios.

On the other hand, according to a control signal is installed between the heat source equipment 14 for warming the hot water of the return pipe 17, the return pipe 17 and the heat source equipment 14, the flow rate or pressure difference of the return pipe 17 It is provided with a sensor 15 for measuring.

Here, the various devices 11 may be any device that can receive the current heating pipe state, such as a room controller attached to the wall of the room or an app of a smart phone. For example, a PDA owned by the A / S staff of a boiler company and a computer that can access the Internet.

In other words, the heating piping system of the house or the heating piping system of the occupied office can be checked in real time from a computer with internet access, so the branch office of the local boiler company or the regional management office can check the normal status of the heating piping system installed in the area. It can be checked periodically to improve work efficiency or service efficiency.

On the other hand, the sensor 15 may be a variable flow rate sensor or a pressure difference sensor, if the variable flow rate sensor is provided in the heat source equipment 14 may be used without changing the flow rate sensor, but the present In the specification, a specific operation flow will be described using a variable flow sensor.

2 is a flow chart showing the operation flow of the heating piping system using a sensor according to the present invention, the supply pipe 16, the return pipe 17, the sensor 15, the heat source equipment 14, the control unit 12, the display unit (13) looks at the heating pipe control method using the sensor using the various devices (11).

A second step (S22) of setting an alarm condition by receiving a setting value for an alarm condition from the user through the various devices 11 is performed.

The controller 12 proceeds to a third step S23 of calculating a set value in order to compare a value currently measured by the sensor 15.

The controller 12 performs a fourth step S24 of determining whether a value currently measured in the third step S23 is lower than a set value.

If the value currently measured in the fourth step S24 is lower than the set value, a fifth step S25 of transmitting a cleaning signal from the controller 12 to the various devices 11 is performed.

On the other hand, the above-described heating pipe control method is applicable to both individual heating and district heating, but in the case of district heating can receive the fluctuation flow rate from the central control room.

In detecting the value of the flow rate in the heating pipe, when receiving a flow value through communication from another device, that is, including the flow rate for each heating section, the flow rate for each heating section receives a value by checking the flow rate by opening a sphere.

This value is used to monitor the fluctuating flow rate to generate a cleaning signal.In the case of non-communication devices, the system checks the total flow rate and gives a contact signal so that the entire flow rate can flow through the device at regular intervals. The cleaning signal is generated by monitoring the flow rate value. In the case of the differential pressure sensor, a cleaning signal is generated by monitoring the variable differential pressure value using the same algorithm as described above.

In addition, the range for the variable flow rate value or the variable differential pressure value may be set to vary the setting range according to the site and heating load conditions.

As described above, when the heating pipe is controlled using the sensor, the degree of blockage of the pipe can be checked numerically, so that the user can display the degree of blockage of the heating pipe by numerical value or clean the heating pipe by voice or image. I can display it to the administrator.
