Hereinafter, an embodiment of an apparatus and method for alarming and maintaining an anti-freeze system using a freeze prevention system and a smart device according to the present invention will be described with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a schematic diagram illustrating an alarm and maintenance device of a system for preventing a frost damage using a smart device according to an embodiment of the present invention. Referring to FIG.

As shown in FIG. 1, the alarm and maintenance apparatus of the anti-freeze system using the smart device according to an embodiment of the present invention includes an anti-freeze system 100, a server 210, a database 220, And includes a computer 310 and a smart device 320 as means for receiving alarm information according to the operation state of the freeze prevention system 100 and remotely controlling the operation of the freeze prevention system 100. [

The frost protection system 100 detects the state of the piping.

For example, the frost protection system 100 can detect the piping temperature or the temperature (water temperature) of the water contained in the piping, and the flow rate and the flow rate through the piping. Therefore, it may include at least one sensor (for example, an acceleration sensor, an ultrasonic sensor, a temperature sensor, a pressure sensor, a flow velocity / flow rate sensor, a velocity sensor, etc.) for detecting the pipe temperature, water temperature, flow rate and flow rate.

The frost protection system 100 controls the operation of the piping.

For example, the frost protection system 100 can directly heat the water in the pipe or the pipe, or control the temperature around the pipe. To this end, it may include an electric heater 121 (see FIG. 2) for directly heating water in the plant.

The frost protection system 100 can also numerically control the valve 122 (see FIG. 2) connected to the piping. That is, the degree of opening of the valve can be controlled. The valves 122 are electrically remotely controlled valves and may be connected in series with a manual valve (not shown) manually opened / closed by the user. It is not necessary to connect a separate manual valve (not shown) in series when the valve 122 includes a manual operation function.

In other words, the valve 122 is a valve capable of remotely controlling the discharge direction of water, so that the discharge direction is set to the manual valve side connected in series at the normal time, and the discharge direction of the water is immediately set to the outside at the time of remote control. The opening degree of the valve 122 can be controlled to control the flow rate and the flow rate. The larger the opening of the valve 122, the greater the flow rate and the flow rate, and the smaller the opening of the valve 122, the smaller the flow rate and flow rate.

Since the piping for heating generally has a circulation structure, it does not cause freezing or freezing as long as the boiler (not shown) operates. However, when the water is not used for a long time at a low temperature, Freezing or freezing will occur in the case where water is not discharged from the water.

Therefore, the freezing prevention system 100 can prevent freezing or freezing of the piping by automatically controlling the heating or flow rate (or the flow rate) (when the mode is set to the automatic mode). If the automatic mode is not set, the status is notified to the administrator, and the freezing prevention system 100 is remotely controlled by the manager so as to prevent freezing or freezing of the piping.

The frost protection system 100 alerts the administrator of the state of the piping and receives remote control from the manager.

For example, the freezing prevention system 100 collects and stores information on the state of the piping 10, that is, the piping temperature, the water temperature, the temperature around the piping, the flow rate and the flow rate, (Or a critical point set for an alarm to an administrator before freezing or freezing occurs) at which the freeze wave can occur, and then, when the state of the pipe reaches the critical point, And output it to the server 210. The controller receives the remote control signal from the controller that receives the alarm signal, and controls the temperature, flow rate, and flow rate of the pipeline to prevent freezing or freezing.

Meanwhile, the freezing prevention system 100 outputs the status information of the piping to the server 210 at regular time intervals (or periodically), compares the state of the piping with the server 210 to see whether the piping reaches the critical point, When the state of the pipe reaches the critical point, the state of the pipe and an alarm signal may be directly outputted to the manager (i.e., the manager terminal). That is, the state of the piping and the alarm signal can be output through the computer 310 or the smart device 320 which is an administrator terminal.

The server 210 receives a remote control signal from the manager (i.e., an administrator terminal) and transmits the remote control signal to the wireless wave management system 100. The wireless wave management system 100 controls the wireless wave management system 100, By controlling the temperature, flow rate and flow rate, freezing or freezing can be avoided.

The smart device 320 may be implemented to be suitable for various functions but may change or expand a substantial part of functions through an application program (APP). For example, (Smart phone), a smart tablet, a smart pad, a smart TV, a smart key, and a smart card.

Especially for smart phones, it integrates data communication functions such as internet access to existing mobile phone functions. In other words, even if you do not connect to a wired Internet or a WiFi that requires you to use a fixed password, smart devices can access the Internet anytime and anywhere via the mobile communication network, It is advantageous to be able to connect directly to the network.

Therefore, according to the present invention, by utilizing the advantages of the smart device as described above, various data related to the maintenance and repair of the freezing prevention system and software And confirms the operation state of the water and piping through the connected server, so that the maintenance work can be performed remotely easily at anytime and anywhere. You can also search for stored information.

The smart device 320 and the computer 310 may be referred to as an administrator terminal.

At this time, the server 210 may be a computer having an IP (Internet Protocol) address registered in advance, a computer logged in using a pre-registered ID and password, or a computer connected using an address (e.g., a MAC address) The server can be connected to a server storing various data and software related to the maintenance of the freeze protection system through the computer, and the manager can check the operation state of the water and the piping through the connected server 210, It is easy to remotely perform maintenance work on the piping.

At this time, the server 210 includes a mobile management server (second server) 212 that manages access to the freeze prevention system using a smart device and a web management server (third server) that manages access to the freeze prevention system using a computer Server) 213, which are shown in FIG. (First server) 211 (first server) for managing the database 220 in which various data and software related to the management of the servers (e.g., the mobile management server and the web management server) and the maintenance of the freeze prevention system are stored ). That is, it may include servers that perform separate functions.

FIG. 2 is an exemplary diagram showing a schematic configuration of a frost protection system according to an embodiment of the present invention.

2, a freeze prevention system according to an embodiment of the present invention includes a temperature detection unit 110, a temperature and flow rate control unit 120, a heater 121, a valve 122, a control unit 130, A communication unit 140, and a storage unit 150.

The temperature detecting unit 110 detects the pipe temperature, the temperature of the water contained in the pipe, and the temperature around the pipe.

The temperature detector 110 may include at least one or more sensors for detecting temperatures at the various positions.

The temperature detector 110 periodically detects the temperatures in real time under the control of the controller 130 and outputs the detected temperatures to the controller 130. [

The temperature and flow rate controller 120 controls the temperature of the water flowing through the pipe 10. The temperature of the water may be controlled using a separate heater 121 or may be controlled using a boiler (not shown) connected to the pipe 10.

However, unlike the circulating heat pipe which discharges and inflows from the boiler (not shown), in the case of the water pipe, only when the manual valve (for example, faucet) connected to the end of the pipe is opened and water is discharged, ) Can control the pipe temperature by flowing the heated water.

A valve 122 and a manual valve such as a faucet (not shown) are connected in series to the end of the pipe 10 and the valve 122 (for convenience, Remote control valve "). The valve 122 is preferably of a solenoid type that is electrically controlled, but may be controlled by hydraulic or pneumatic, electric, or other actuator method.

The valve 122 may automatically operate according to preset conditions. In other words, when the valve 122 can not be remotely controlled, it is automatically operated to prevent freezing or freezing of the pipe. In other words, the valve 122 may be configured to be remotely controlled by the control unit 120, or may be configured to automatically operate itself without a remote control signal. For convenience of explanation, the configuration and operation of the automatically operated valve (hereinafter referred to as an automatic control valve to distinguish it from the remote control valve) will be described in a separate drawing (see FIGS. 4 and 5 ). Therefore, the valve (remote control valve) 122 can be configured to further include a remote control function in the automatic control valve 400. [

The valve 122 may be installed for every pipe, and may be installed at an inlet connected to each pipe from a boiler (not shown) or an end connected to a manual valve (not shown) of each pipe.

Here, the heater 121 directly controls the temperature of the pipe by using a hot wire (not shown) to prevent the water in the pipe from being frozen. However, the boiler (not shown) There is a difference that piping is not frozen.

The temperature and flow rate controller 120 may control the heater 121, the boiler (not shown), and the valve 122 under the control of the controller 130, and may detect an operation result according to the control It is possible.

The controller 130 can detect the change in the flow rate or the flow velocity that varies when the valve 122 is opened and closed and outputs the detected information to the controller 130. The controller 130 controls the storage unit 150 To be compared with the flow rate or the flow velocity data that varies depending on the amount of opening and closing of the valve 122 stored in the valve 122, so as to determine whether it is a normal operation or an abnormal operation within an error range.

The controller 130 performs an operation for preventing freezing or freezing of the piping 10 according to an operation mode of the freeze prevention system 100 (for example, an automatic mode or a remote control mode). For example, by controlling the heater 121, the boiler (not shown), and the valve 122 to maintain a warm state at a critical temperature (for example, 0 degree) at which freezing or freezing may occur, (Or critical flow rate) of the critical flow rate. The critical temperature may be lower if there is a flow rate in the pipe and the critical temperature may be higher if there is no flow rate in the pipe.

The control unit 130 performs a control operation to prevent freezing or freezing of the pipe 10, and then checks whether the control operation is normally performed. That is, it is checked whether the freezing prevention system 100 operates normally.

The control unit 130 outputs a signal for controlling the heater 121 or the valve 122 that directly heats the water in the equipment to prevent freezing or freezing of the water in the heating unit 121 and the valve 122. However, The normal control may not be performed due to the failure so that the pipe temperature or the water temperature may be kept below the critical point. If the control unit 130 additionally controls the heater 121 or the valve 122 This is because the situation may deteriorate. That is, it is confirmed that the freeze prevention system 100 is in a normal operating state to improve the reliability.

The storage unit 150 stores the temperature detection information, flow rate and flow rate detection information, temperature control information, flow rate, and flow rate control information in real time.

The information stored in the storage unit 150 (e.g., temperature detection information, flow rate and flow rate detection information, temperature control information, flow rate, and flow rate control information) is periodically transmitted to the server 210 in consideration of a communication load. The transmission period of the information is adjusted according to the communication load.

The communication unit 140 transmits information (or data) stored in the storage unit 150 to the server 210 under the control of the controller 130 or transmits a remote control signal from the server 210 to the server 210 And outputs the received signal to the control unit 130.

The communication unit 140 is connected to the server 210 in a wired or wireless manner.

For example, the communication unit 140 can communicate via serial communication including RS232 and RS485, Bluetooth, USB, and Ethernet. In addition, various communication methods can be applied.

Here, the flow rate (or flow rate) is the amount of water flowing through the pipe during the unit time. There are various reasons for the increase of the flow rate. One of the reasons is that the flow rate (Or flow rate) is increased, and the other cause is that the flow rate is increased due to leakage of water due to the cooling of the pipe due to the fall of the temperature.

Therefore, according to the present invention, it is possible to prevent the occurrence of additional leakage by blocking (or closing) the corresponding valve (the valve provided at the front end of the leaked pipe) when the pipe is leaked by the freeze of the pipe, A valve connected to the end of the pipe to which the faucet is connected, or a valve connected to the beginning of the pipe to which the boiler is connected) is opened (or closed) in advance to discharge or block the water, .

Or by heating the temperature of the air around the pipe or pipe by the heating method, freezing or freezing can be prevented.

In the freeze prevention system 100 according to the present invention, the operation for preventing freezing or frost may be performed automatically or may be performed remotely by receiving a remote control signal from an administrator (i.e., an administrator terminal). However, in all cases where the automatic control or the remote control is performed, an alarm operation can be performed to inform the manager (i.e., the administrator terminal) of the state of the piping.

As described above, the present invention enables not only the operation for preventing freezing of the pipe or the freezing of the pipe, but also the automatic quick response (e.g., blocking of the leaked valve) when freezing or freezing occurs in the pipe.

Hereinafter, an alarm and maintenance method of a frost prevention system using a smart device according to an embodiment of the present invention will be described.

3 is a flowchart illustrating an alarm and maintenance method of a frost protection system using a smart device according to an embodiment of the present invention.

3, the controller 130 of the frost protection system 100 detects at least one of the temperature (water temperature) of the water in the pipe 10, the temperature of the pipe, or the temperature around the pipe in real time (S101 ). Also, although not shown in the drawing, the flow rate or flow rate of the pipe 10, or the change in the flow rate or the flow rate, is detected.

In operation S102, the sensed information (e.g., piping temperature, water temperature, temperature around the pipe, flow rate and flow rate, change in flow rate and flow rate, and valve control information) are stored.

The state of the piping can be determined using the sensed information.

That is, it can be determined whether there is a possibility of freezing or freezing of the pipe. The information about the critical temperature or the critical flow rate (critical flow velocity) that may cause freezing or freezing is stored in advance. The critical temperature or critical flow rate (critical flow rate) information may be set by the manufacturer or administrator of the system. Therefore, it may be set temperature or set flow rate (set flow rate).

The pipe 10 can be prevented from freezing or freezing by keeping the set temperature or the set flow rate (set flow rate) or more.

The operation of determining the state of the pipeline may be performed by the controller 130 of the system 100 or may be performed by the server 210 receiving the information transmitted from the system 100, It can be done on both sides. This is because it is necessary to perform the freezing or the freeze prevention operation of the piping 10 even when the abnormal low temperature phenomenon or the communication disconnection state occurs.

The control unit 130 or the server 130 determines whether the water temperature or the pipe temperature is lower than the set temperature from the sensed information (for example, the pipe temperature, the water temperature, the temperature around the pipe, the flow rate and the flow rate, (S103).

That is, when there is a possibility of freezing or freezing from the sensed information (e.g., pipe temperature, water temperature, temperature around pipe, flow rate, flow rate, YES), an alarm is output to an administrator terminal (for example, an administrator's smart device) registered in advance (S104).

In other words, the server 210 compares the status of the piping to the critical point of the detected information, and then, when the status of the pipeline reaches the critical point, the status of the pipeline and an alarm signal to the administrator terminal And the remote control signal is received from the manager terminal and transmitted to the radio wave management system so that the radio wave management system can control the temperature of the pipe, the discharge direction of the water, the flow rate in the pipe And flow rate.

The controller 130 or the server 210 performs a maintenance operation to maintain the piping in a predetermined state to prevent freezing or freezing of the piping 10 (if the automatic mode is set) (S105) . That is, the temperature of the piping or the water flowing in the piping is maintained at a constant level, or the water flowing inside the piping is forcibly discharged and maintained at a certain flow rate or higher than the flow rate to prevent freezing or freezing. In case of the remote control mode, the remote control signal transmitted from the manager can be received and the maintenance operation can be performed remotely.

Then, the controller 130 or the server 210 checks whether the freeze prevention system 100 operates normally (S106). That is, the maintenance operation must be performed when the freezing prevention system 100 is in normal operation to prevent additional safety accidents. For example, the operating state can be determined according to whether the temperature has increased by the power applied to the heater 121 and the application time, or the flow rate or flow rate has been adjusted by the opening / closing control of the valve 122 Or a response signal output from the heater 121 or the valve 122, and determines whether the response signal is normally operated.

If the freezing prevention system 100 is not in the normal operation state (NO in step S106), the flow returns to step S104 to output an alarm to the administrator, and a maintenance operation corresponding to the abnormal operation state of the freezing prevention system 100 (S105). For example, stopping and initializing the additional control of the heater 121 and the valve 122, and allowing the manager to check the status.

When the freeze protection system 100 is in a normal operation state (YES in step S106), the alarm operation (S104) and the maintenance operation (S105) of the pipeline are performed normally.

As described above, the present invention can improve the reliability of the system by determining whether the operation of the freeze prevention system 100 is normal and controlling the maintenance operation of the pipeline, and can prevent the occurrence of secondary safety accidents And prevent freezing or freezing by aggressive operation such as temperature control, flow rate and flow rate control.
