Valve information transmitting and receiving device for water separator valve {VALVE INFORMATION TRANSMITTING AND RECEIVING DEVICE FOR WATER VALVE}

TECHNICAL FIELD The present invention relates to a valve information transmitting and receiving device for a water valve, and more particularly, from a tap water valve (gate valve or butterfly valve) installed in an underground valve chamber or a valve box, valve information (valve year of manufacture). The present invention relates to a valve information transmitting and receiving device for a dilution valve, in which a distillation valve operation manager can easily obtain a distillation valve installation site.

Although a water separator valve (gate valve or butterfly valve) may be operated by a handle, a water separator valve used in a water supply drainage system is, as illustrated in FIG. 2, mostly inside the valve chamber 17 or the valve box 19. Since it is installed in the lower part, most of the key opening / closing valves operated by the metal (mainly cast iron or steel) valve key 23 are the same. The valve key 23 is composed of a key box 25 having a rectangular hollow, a handle 29 that can be held and turned by a worker, and a long stem 27 connecting the key box 25 and the handle 29. It is configured. Therefore, all the water valves operated by the valve key 23 have a valve seat 3, as shown in FIG. 2, and the upper side of the valve seat 3 has a key box () of the valve key 23. The metal valve cap 5 in which the square head 7 inserted into 25 is detachably joined. Although only the front view of the gate valve connected to the piping 15 was shown in figure, the butterfly valve also has the metal valve cap 5 the same point.

Most tap water valves are buried underground. If the distillation valve or piping is installed shallowly from the ground, the distillation valve or the piping may be damaged by the pressure or shock applied from the ground, so the valve chamber should be as low as 1 ~ 2m and as deep as 8 ~ 10m. (17) or the valve box (19) is to be installed in this place to install a water separator valve. If the valve chamber 17 is wide and an operator can enter and exit, it also serves as a manhole function, and the ground opening is closed with a manhole cover at this time. However, as shown in FIG. 2, when the valve chamber 17 is narrow or when only the valve box 19 is installed without the valve chamber, the operator cannot enter or exit the interior, and the ground opening is closed by the drawer 21. . Since the space where the distillation valve is installed is a valve chamber or a valve box in the ground, water and earth and sand are easily introduced around the distillation valve and are dark even during the day because there is no separate lighting.

The person who manages the distillation valve installed in this way (hereinafter referred to as “operation manager”) is illustrated in FIG. 1 for determining the replacement time of the distillation valve, requesting repair of the distillation valve, opening and closing the valve for repairing the pipeline, and the like. The year (manufacturer), the standard (diameter) of the valve by the installation point, the valve seat rotation speed when opening and closing the valve by the installation point (in this specification, such information necessary for the operation management of the valve is referred to as "valve information"). Must be known correctly). In particular, the dimensions (diameter) of the distillation valve are important information for the distillation valve operation manager because it allows them to know at what stage in the drainage system (e.g., the final consumer stage, the pressurization stage, or intermediate stage). The valve stem rotation speed is very important because when the valve is opened or closed to close or open the dividing valve, it may damage the valve disc, causing water leakage, and damage the screw and nut to shorten the distillation valve life. Information. Such valve information is information that must be accurately identified whenever necessary to open and close the water supply, such as temporary local separation of the water supply pipe, establishment of the water supply pipe, and maintenance and cleaning of the water supply pipe.

Conventional water supply pipe and water valve operation managers have stored the information about each valve in the book, but each operation manager has a large number of water valves to manage, and not only frequent replacement of the operation manager. Since new water valves and pipelines have been frequently installed or abolished, it is difficult to effectively use the loaded valve information when the water valve needs to be opened and closed.

The valve information can be displayed on the cover or the manhole cover, but the cover or the manhole cover is installed in a place where a vehicle or a person passes, so that the marking can be easily removed, and in the case of the manhole, several dividing valves are installed in one manhole. In this case, there is a problem that it is difficult to identify which distillation valve is related to the valve information displayed on the manhole cover.

Although valve information can be displayed on the water dispenser valve, most of the water dispenser valves are installed in the valve chamber or the valve box, and valve opening and closing is done by opening the manhole cover or the lid and opening the valve. Even in one case, there is a problem that it is difficult to accurately identify it on the ground.

The present invention has been made to solve the above-mentioned problems in the operation management of the conventional water valve, the first problem to be solved by the present invention can readily obtain the valve information necessary for the water valve operation manager at the water valve installation site immediately. The present invention provides a valve information transmitting and receiving device for a dilution valve.

The second problem to be solved by the present invention is to provide a valve information transmitting and receiving device for a dilution valve that can minimize the power consumption of the valve information transmission unit installed in the dividing valve.

The third problem to be solved by the present invention is the valve information transmitting and receiving device for the water discharge valve that the valve cap emits light so that the valve key can be easily inserted into the valve cap when opening and closing the water discharge valve installed in the ground using the valve key on the ground To provide.

The first object of the present invention described above is composed of a valve information transmitting unit provided in the valve cap of the dividing valve, and a valve information receiving output unit provided in a portable terminal, the valve information transmitting unit and the memory storing the valve information number; And a radio frequency transceiver for wirelessly transmitting the valve information number stored in the memory, and a microcontroller unit for controlling the radio frequency transceiver to transmit the valve information number stored in the memory only under a predetermined condition. The valve information receiving output unit includes a radio frequency transceiver for receiving a valve information number from the valve information transmitting unit, a memory storing valve information matching the valve information number, and valve information matching the valve information number received by the radio frequency transceiver. Voice synthesis or text to external voice Or a valve information transmitting / receiving device for a dilution valve, characterized in that it comprises a valve information display device for outputting a text.

The second object of the present invention described above further includes a trigger switch that is triggered by light, magnetic field, or impact on the valve information transmitting unit, and a human light is applied to the trigger switch. This is solved by having the microcontroller unit control the memory and the radio frequency transceiver to transmit the valve information number only when an impact is applied.

The third object of the present invention described above further includes an LED (LED) controlled by the microcontroller unit in the valve information transmitting unit, wherein the microcontroller unit has a light, magnetic field or impact applied to the trigger switch. This is solved by controlling the LED to flash temporarily before or after transmitting the valve information number.

According to the present invention, a number of distillation valves installed in the water supply and drainage system store valve information numbers unique to the distillation valve for each distillation valve in the valve cap, and under constant conditions (valve cap shock by the user, flash irradiation, Or the valve information number is transmitted to the terminal carried by the valve operation manager in response to the approach of the magnet, and the terminal displays the valve information corresponding to the valve information number transmitted from the dividing valve on the terminal by voice or text. The valve information transmitter can easily obtain the necessary valve information at the distillation valve installation site immediately, and there is no constant condition (valve cap shock, flash irradiation, or magnet access by the user). Since the operation is stopped to consume no power, the power consumption of the valve information transmission unit installed in the dividing valve is reduced. When the valve is opened and closed, if a certain condition (shock, light or magnetic field) is applied, the LED (LED) installed in the valve cap emits light, so the valve key is used when opening and closing the distillation valve installed in the ground using the valve key from the ground. There is an effect that can be easily inserted into the valve cap.

As shown in FIG. 2, the valve cap 5 is coupled to the valve seat 3 at the upper end of the dilution valve. The valve cap 5 has an upper rectangular head 7 (usually a square pillar shape that extends toward the lower part), a flange 9 extending outward from the lower corner of the rectangular head, and the valve stem 3. The upper end of the neck 11 is inserted and fixed.

The valve information transmitting part 31 preferably forms a downward groove on the upper surface of the square head 7 of the valve cap 5 and is installed there. At this time, it is preferable to protect the valve information transmitter 31 from foreign substances such as moisture and soil by filling the groove completely with resin such as epoxy while the valve information transmitter 31 is inserted. . The groove formed in the square head 7 is preferably a circular groove, and the substrate shape of the valve information transmitter inserted therein is preferably formed in a rectangular shape to stand in a vertical direction, or in a circular shape to lay down horizontally.

As shown in FIG. 3, the valve information transmitter 31 includes a memory 33 in which valve information numbers are stored, a radio frequency transceiver 37 wirelessly transmitting valve information numbers stored in the memory 33, and And a microcontroller unit 35 for controlling the radio frequency transceiver 37 to transmit the valve information number stored in the memory 33 only under a predetermined condition. As shown in FIG. 5, the same valve information number is given to the distillation valve having the same manufacturing year, manufacturer, specification (diameter), and rotation speed, and stored in the memory 33. The memory 33, the radio frequency transceiver 37, and the microcontroller unit 35 may be integrated in one semiconductor chip, such as the nRF24LE1 chip, a system chip of Nordic Semiconductor of Norway.

A trigger switch triggered by a light, a magnetic field, or a shock to give the valve information transmitter 31 a predetermined control condition to the microcontroller unit 35. And the microcontroller unit 35 controls the memory 33 and the radio frequency transceiver 37 to transmit the valve information number only when a person applies light, a magnetic field or an impact to the trigger switch. It is desirable to.

The trigger switch reacts by light includes a CdS cell 41. Since the internal resistance of the CdS cell 41 changes according to the intensity of the light energy irradiated, the intensity of light energy to be irradiated is set to be higher than or equal to a predetermined level. It is possible to input an on signal or an off signal to the microcontroller unit 35 at a predetermined level or less. In this case, the on signal may function as a valve information transmission control condition to the microcontroller unit 35. As illustrated in FIG. 2, the CdS 41 cell 41 may apply light necessary for operation by using the flash 63.

As shown in FIG. 2, the reed switch 43 drives the magnet 13 to the bottom surface of the key box 25 of the valve key 23, and the key box 25 approaches the valve cap 5. The necessary magnetic field can be applied.

In FIG. 3, the shock sensitive switch 39, the CdS cell 41, and the reed switch 43 are connected in parallel to each other to provide a triggering signal to the microcontroller unit 35. It is not necessary to use all of the trigger switches. Only one type of trigger switch (e.g. shock switch) may be used, or only two types (e.g. shock switch and reed switch connected in parallel) may be used. .

In addition, as shown in FIG. 3, the valve information transmitter 31 further includes an LED (LED) 45 controlled by the microcontroller unit 35, and the microcontroller unit 35 is It is preferable to control to temporarily flash the LED 45 before or after transmitting the valve information number when light, magnetic field or impact is applied to the trigger switch 39 or 41 or 43. Why the LED 45 to operate in this way is easy to understand with reference to FIG. There is no separate lighting device inside the valve chamber 17 or the valve box 19 in which the distillation valve is installed, and the distillation valve operation manager is required regardless of day or night (for example, in case of a freezing accident or piping leakage). To open or close the lid (21) or the manhole cover must be opened and closed. Therefore, it is not easy for the dividing valve operation manager to insert the key box 25 of the valve key 25 into the square head 7 of the valve cap 5 in order to open and close the dividing valve. This is because it is difficult to accurately locate the valve cap. However, if the LED 45 flashes in the valve information transmission unit provided in the square head 7 of the valve cap 5 when the trigger switch is activated, the dilution valve operation manager is allowed to enter the key box 25 of the valve key 23 from the ground. ) Can be accurately inserted into the square head (7) of the valve cap (5).

Can be. If necessary, only the valve information voice output devices 57 and 59 for synthesizing the valve information and outputting only voice can be used, or only the text display devices 63 and 65 for characterizing the valve information and outputting them as text. . That is, the valve information display device includes at least one voice output device or a text display device. The voice output device includes a voice synthesizer 57 and a speaker 59, and the text display device includes an LCD driver 63 and an LCD. (LCD). The microcontroller unit 51 receives the valve information number from the radio frequency transceiver 51, reads the valve information corresponding to the valve information number into the memory 55, and outputs the voice output device 63 or 65. The text display devices 63 and 65 control the valve information to be output by voice or text. As shown in FIG. 5, the memory 55 stores valve information matching each valve information number.

According to the configuration of the valve information transmitting and receiving device according to the present invention, the dilution valve operation manager impacts the valve cap 5 with the valve key 25, or the flash 63 is illuminated toward the valve cap 5. When the key box 25 of the valve cap 5 approaches the valve cap 5, the valve information transmitting unit flashes the LED 45 to display the position of the valve cap square head 7, The valve information number is transmitted, and the valve information receiving output unit outputs the valve information corresponding to the valve information number by voice or text.
