Description

Automatic valve position measuring apparatus by using education effect for each room in each heating system}

The present invention relates to a method for automatically controlling the valve opening amount in each heating system through a learning function, and more particularly, by adding a learning function to each heating system, a time due to a heating imbalance problem caused by a pipe length or an external environmental condition. After measuring the return temperature of each room, the proportion of control of the amount of heat supplied to each room can be drastically reduced by the proportional control method using the learning function. Invented to provide a fast and appropriate distribution of heat required by the unit so that the heating temperature of each room can reach a quick equilibrium state, which can greatly reduce heating efficiency and energy.

Generally, a boiler is used to heat water by using combustion heat and heat generated by burning it using fuel, coal or gas as fuel, or supplying electricity to a heater, and supplying hot water to various heating facilities In the case of a domestic boiler, hot water is supplied to the piping installed on the floor of the room or the like, and is used for supplying hot water through a water pipe or the like.

On the other hand, in buildings with several rooms, such as inns, test houses, and studios, each room is equipped with a separate room temperature controller, an energy-saving automatic heating system that separately controls the room temperature. Each room is equipped with a heating system.

Looking at the configuration of each room heating system, such as a heating source or individual boiler, each room controller and several room cones installed in each room, the living room installed in each room to monitor the status of hot water use, including the heating conditions of each room A central room cone for heating control of a room (for example, a living room) in which the room cone is installed, a valve for controlling the number of heating in each room (ie, a heating water supply control valve) and a valve driver for controlling opening and closing of the valve Doing.

By the way, when the conventional valve heating system adopts a simple on / off control method, the floor temperature is different depending on the size (pipe length) of the room to be heated. The method of controlling the flow rate of the pipe by installing the sensor has a lot of problems of durability and reliability of the sensor.

In addition, even in the case of controlling the return temperature of each pipe (room) by measuring the return temperature in each conventional heating system, the user must set the length of the pipe (room) in advance or set a target return temperature for each room. There is a problem that it takes a lot of time to follow the inconvenience, and to proportionally supply the heat amount of each pipe, and to correct the frequent trajectory of the valve driver to reach the equilibrium point where the heat amount required for each pipe is supplied Not only is this being done, there is a disadvantage that the equilibrium temperature may not be reached even if the opening amount of the valve is modified through frequent frequent corrections.

That is, when the floor temperature is different depending on the size of the room to be heated (pipe length), the floor temperature of each room can be kept similar by using a proportional control system. After the process of adjusting the valve opening degree, the process of adjusting the valve opening degree of each room for the proportional control in the future even under the same heating conditions.

By the way, in the prior art, the amount of opening adjustment of the valve was obtained through proportional control for a certain condition (combination of rooms to be heated), but if the heating is to be performed for the same condition again, the opening degree must be adjusted again. Therefore, it is necessary to repeat the series of steps necessary to control the opening degree, so it takes a long time for the heating temperature to reach saturation.

The present invention has been made to solve such a conventional problem, by adding a learning function to each heating system, the heating control time according to the heating imbalance problem caused by the length of the pipe or the external environmental conditions, etc. In the process of proportionally controlling the amount of heat supplied to each room after measurement, it can be drastically shortened by using the learning function to proportionally control and required for heating pipes of different heating areas. It provides automatic control of valve opening amount in each room heating system through learning function that can greatly reduce heating efficiency and energy by supplying fast and proper distribution of heat quantity. The purpose is to provide.

In order to achieve the above object, the present invention provides a heat source or a boiler, each room controller, an indoor temperature detection sensor, several room cones installed in each room, a central room cone having a learning function key, and a heating number for each room. In each heating system having several valves, several heating return temperature detection sensors for detecting the heating return temperature passing through each valve, and several valve actuators controlling the opening and closing of the valves under the control of the controller. CLAIMS 1.

On the other hand, the user does not "on" the learning function key in the above, or if the learning function application data has not been previously entered into the storage device in itself, or was previously in the heating "on" or heating "off" state If no heating "off" or heating "on" signal is input at any of the room cones, starting proportional control heating for the rooms; Then determining whether the user's desired room temperature has been reached during proportional control for each room; As a result of the above determination, if the room temperature of each room reaches the target temperature desired by the user, the valve opening amount of each room being heated and the tapping temperature of the heat source or the boiler are stored in the storage device, and then the heating control of each room is performed through the known proportional control system. Performing a step; As a result of the above determination, if the room temperature of each room does not reach the desired target temperature, the heating “off” or heating “on” signal is output from any one of the room cones that were previously in the heating “on” or heating “off” state. If it is determined that the change signal is inputted (that is, heating "off" or "on" signal) is inputted, the process returns to the initial stage, and if there is no input of the change signal, the proportional control heating for the rooms is started. Step of returning; characterized in that the further implementation.

As described above, according to the present invention, by adding a learning function to each heating system, the heating control time according to the heating imbalance problem caused by the pipe length or the external environmental conditions is measured and then supplied to each room after measuring the return temperature of each room. In the process of controlling the amount of heat to be proportionally controlled, it is possible to greatly reduce the proportion by using the learning function and to distribute the amount of heat required by heating pipes in different heating areas quickly and appropriately. By supplying the heating temperature of each room to reach an equilibrium state is a very useful invention, such as to significantly reduce the efficiency and energy of heating.

And a step (S6) of returning to the first step (S1) when the change signal of the previous state (that is, the heating " off " or " on " signal) is input.

On the other hand, when the user does not "on" the learning function key in step S1, or when learning function application data is not previously input to the storage device in the step S2, or in step S6. ), If no heating " off " or heating " on " signal is input to any of the room cones that were previously in the heating " on " or heating " off " state, starting proportional control heating for the rooms ( S7);

As a result of the above determination, if the room temperature of each room reaches the desired target temperature of the user, the valve opening amount of each room being heated and the tapping temperature of the heat source or the boiler are stored in the storage device (S9), and then each room is known through the known proportional control system. Performing heating control of the apparatus (S10);

As a result of the determination in step S8, if the room temperature of each room does not reach the desired target temperature, the heating " off " or the " heating " It is determined whether the ON "signal is input (S11), and when the change signal of the previous state (that is, the heating" off "or" on "signal) has been inputted, the process returns to the first step S1. Returning to the step (S7) to start the proportional control for the heating; characterized in that the further implementation.

At this time, the heating "on" signal is transmitted from the room cone (3), the room temperature is lower than the user's heating set temperature, or when the user presses the heating "on" switch or heating set in each room The valve is characterized in that either state when the "on" time.

The operation and effect of the method of the present invention having the above steps will be described as follows.

First, each room heating system to which the method of the present invention is applied includes a room controller 2 including a heat source or a boiler 1 including a district heating system, a storage device such as a learning function key 81 and an EEPROM, and the like. Each room is equipped with an indoor temperature detection sensor 31 and detects the heating return temperature passing through several room cones 3 installed in each room, several valves 4 for controlling the heating water in each room, and valves 4 in each room. Several heating return temperature detection sensors 6 and several valve drivers 5 for controlling the opening and closing of the valves 4 under the control of the controller 2.

In the controller 2 of each heating system having such a configuration, it is usually determined whether the user "turns on" the learning function key 81 for operating the proportional control system for each room installed in the central room cone 8 (S1). If the user "turns on" the learning function key 81, it is determined whether the learning function application data for each room desired to be heated is already input to the storage device in the self (S2).

As a result of this determination, if the learning function application data is already input, the opening amount of the valve 4 and the tapping temperature of the heat source or the boiler 1 of the rooms in which the heating "on" signal is transmitted among the several room cones 3 are transmitted. It is carried out by applying to the learning function application data (S3).

That is, a series of opening amount adjustments to the valves 4 of the respective rooms in which the heating " on " signal is transmitted, and the opening amount and heat source of the valves 4 of the rooms in the heating " on " Alternatively, the tapping temperature of the heat source or the boiler 1 may be adjusted, including the valve opening amount of each room to be heated by using data inputted in a memory device such as EEPROM without adjusting the tapping temperature of the boiler 1. Automatic control and heating.

Therefore, not only can the heating temperature for each room be increased to the temperature desired by the user in a short time, but also the heating temperature of each room can be quickly and appropriately distributed and supplied by the heating piping of each room with different heating areas. Achieves a fast equilibrium state, which significantly reduces heating efficiency and energy.

In addition, the controller 2 determines whether the user's room temperature (that is, the target temperature) has been reached for each room of the user by applying the learning function application data as described above (S4). When the room temperature reaches the desired target temperature of the user to control the heating of each room through a known proportional control system for each room corresponding to the input control program (S5).

However, as a result of the above determination, if the room temperature of each room does not reach the desired target temperature of the user, the heating "off" or heating at any one of the room cones 3 which were previously in the heating "on" or heating "off" state. It is determined whether the "on" signal is input (S6), and if the change signal of the previous state (that is, the heating "off" or "on" signal) is input, the subsequent steps of returning to the first step S1 are repeated. do.

At this time, the heating "on" signal is transmitted from the room cone (3), the room temperature is lower than the user's heating set temperature, or when the user presses the heating "on" switch or heating set in each room When the valve is "on" time means either state.

On the other hand, if the user has not "on" the learning function key in the first step (S1) of the steps, or if the learning function application data is not previously input to the storage device in the step (S2) or If no heating "off" or heating "on" signal is input to any of the room cones that were previously in the heating "on" or heating "off" state in step S6, then the general proportional control heating for the rooms It will start (S7).

In this way, the general proportional control for each room determines whether the target temperature is reached at the room temperature for each room desired by the user (S8), and if the room temperature of each room reaches the desired target temperature for the user to apply the learning function later. The valve opening amount and the tapping temperature of the heat source or the boiler of each heating room are stored in the storage device (S9), and then heating control of each room is performed through a known each room proportional control system (S10).

However, as a result of the determination in step S8, if the room temperature of each room does not reach the desired target temperature of the user, the heating is “off” or at any one of the room cones that were previously in the heating “on” or heating “off” state. It is determined whether the heating "on" signal is input (S11), and when the change signal of the previous state (that is, the heating "off" or "on" signal) is input, the process returns to the first step S1 and repeats the subsequent steps. If there is no input of the change signal, the process returns to step S7 of starting general proportional control heating for the rooms and repeats the subsequent steps.
