Description

Network box of fountain network control system

The present invention generally relates to a fountain control technology installed in an open water tank or a bottom-type water tank, and more particularly, it is easy and simple to install a system for controlling elements such as a nozzle, a submersible lamp, and a pump constituting the fountain. The present invention relates to a network box of a new fountain network control system that is easy to remotely control and that the error state of each fountain component can be easily monitored using two-way communication during the control process.

In general, the fountain is a device that creates a specific decorative atmosphere using the water by spraying the water contained in the reservoir to the high pressure upwards. The fountain consists of a number of nozzles, submersible lamps (or fountain lamps) and pumps in the water of the reservoir, and each nozzle is provided with a solenoid valve. In recent years, LED lighting fountains have been installed for nighttime lighting. By controlling pumps, valves, and nozzles among the components of the fountains, the water in the tank can be controlled in a decorative and plastic pattern in which the water is ejected upward by high pressure, and by controlling the LEDs forming the fountain lamps. It gives a colorful effect to the erupting water stream at night. Recently, it is common to program and control the pattern of fractions implemented in a fountain by a unit of time.

In the conventional general fountain, as shown in FIG. 1, the fountain 2 and the operating room 1 for its control are installed at an average distance of about 200 m. The fountain 2 includes several components, such as valves 22 and 24 and submersible lamps 26 and 28. In the operating room 1, various shapes of the fountain can be formed by controlling the power supplied to these fountain components. Will be implemented. To this end, the operating room 1 includes a control computer 12 and a switchboard 14 operated by an operator, and the switchboard 14 includes a relay controlled by a programmable logic controller (PLC) 142. Set 144 is provided. The relay set 144 controls the supply of power in an on / off manner according to a control pattern that is constantly programmed by the PLC 142 to control valves and submersible lamps, which are components of the fountain 2 from the power supply 146. It is possible to control the power supplied to 22, 24, 26, 28.

However, the conventional fountain system shown in FIG. 1 requires a power supply line that is individually connected between the operating chamber 1 and the fountain 2 to each of the components constituting the fountain 2. As a result, a large amount of wires are required to increase the cost, as well as the wiring structure is complicated, there is a problem that is prone to failure.

Therefore, there has been a proposal to simplify the wiring structure between the operating room and the fountain among the above-described fountain structure. For example, in the publications of Korean Patent Registration No. 10-0715799 “Fountain Fountain Control Device” and Patent Registration No. 10-0740667 “Fountain Fountain Control Joint Box”, a relay set installed in a conventional operation room is separated from the operation room and placed near the fountain. It proposes a structure for connecting with a communication line between the relay set and the relay set. As shown in FIG. 2 attached to this specification, according to this technique, the operating room 1 supplies power to the valves 22, 23, 24 and the submersible lamps 26, 28, which are various components of the fountain. The control joint box 30 for controlling by the instruction from the structure is located near the fountain. The operating room 1 is a control computer 120 and a PLC 118 for driving the power supply 112 and a control program and transmitting control commands, except for a relay set, and a PLC 118 and a control joint box ( 30) a communication board 114 for communication therebetween. Meanwhile, the control joint box 30 includes a communication unit 320 for receiving a command from the operating room, a power supply unit 310 for receiving power, an LCD display unit 340 for displaying an operation state, components of the fountain 22, The controller 330 is provided to control each relay by the relays 360 connected to the 23, 24, 26, and 28 and the command received from the communication unit 320. According to this Rainbowscape's proposal, only a cable including one communication line and a power line is connected from the operating room 1 to the fountain, and the connection from the relay to each of the components of the fountain is relatively short. ), The wiring distance is shortened and the cost can be reduced.

However, in the above-described patent registration numbers 10-0715799 and 10-0740667, the control joint box 30 and the PLC 118 of the operating room 1 should be connected in series lines, respectively. Therefore, in order to control a large number of fountains included in such a large fountain system in one operating room when constructing a large fountain system, as shown in FIG. Although 32, 34, and 36 may each have an ID input 360 for identification, they must be connected in series with the operating room 1, respectively, so that the wiring between the operating room 1 and the fountain is still complicated. There is.

Furthermore, for the communication between the PLC 118 and the control joint box 30, since there is no communication function of the PLC 118 itself, a separate communication board 114 is required, and such a communication board 114 In addition, a separate PLC input / output (I / O) board 116 is further required for the connection with the PLC 118, and there is a problem that components in the operating room 1 increase.

In particular, the control joint box 30 has a problem that it is impossible to detect or correct additional errors. That is, since the control joint box 30 can only perform the on-off operation of each relay 360 contact point in the control unit 330, the communication board 114 of the operating room 1 is simply a control joint rather than a full-fledged communication device. It only serves to transmit only the control signal to the box (30).

The present invention is designed to improve the conventional fountain control system and provide additional advantages, it is easy to install and simple configuration of the system for controlling the components of the pipeline, nozzle, submersible lamp, pump, etc. It is an object of the present invention to provide a network box of a new fountain network control system that is easy to remotely control and that the error state of each fountain component can be easily monitored using two-way communication in the control process.

Hereinafter, a detailed example of a network box of a fountain remote network control system according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a schematic block diagram showing the configuration of a fountain remote network control system and a network box according to an embodiment of the present invention, Figure 4 is a network box of a fountain remote network control system according to an embodiment of the present invention A schematic flow chart of the operation flow.

As shown in FIG. 3, the fountain network control system and its network box provided by the present invention relate to a control device for controlling and monitoring the fountain. The control system comprises the components of a fountain installed in a remote reservoir in accordance with the instructions of the control computer 424 of the fountain control computer 42 installed in an operating room which can be remotely located, for example, from 100 to 500 m. 222, 224, 226, and 228.

In the present invention, the components of the fountain, i.e., the water lamp or the fountain lamp and the valve 222, the motor and valve 224 of the pump, the swing nozzle 226, or the valve 228 and the position adjacent to the installation Characterized by a network box 46 of a fountain control system for controlling the components.

Controlling the fountain through the network box 46 is a fountain control computer 42, which has a power supply 422 and a control computer 424. Between the fountain control computer 42 and the network box 46, the power line connected between the power supply 422 and the power supply 461 of the network box, and the connection between the control computer 424 and the communication unit 462 of the network box. Only a control line or a communication line for transmitting the control signal is required. Components such as valves, fountain lamps, nozzles, etc. of the fountain are connected to the network box 46.

The network box 46 is basically a fountain joint box configured to receive control commands from a remote fountain control computer 42 and directly control components of an adjacent fountain, but receives a control signal as a digital signal. Have This may provide an advantage that, unlike the on / off control method by the conventional relay, for example, a fountain lamp composed of LEDs, not only the on / off control of the LED but also the intermediate brightness control (dimming) is possible. The network box 46 can be placed in water in a reservoir, for example, in a state of being embedded in a waterproof housing.

The network box 46 may basically include a plurality of output modules 468, a communication unit 462, and first and second control units 463 and 464. In addition, the power supply unit 461 receives power from the fountain control computer 42, and a display unit 465 capable of displaying information such as an operation state and error detection. The network box 46 may be provided with an address input unit 466 for inputting an address for identification after being installed at a specific location.

The plurality of output modules 468 are respectively connected to the fountain components 222, 224, 226, and 228 to directly control the operation and detect an error. It may include a communication buffer for amplifying and making a signal resistant to noise, an IPM for protecting a network box, an error detection unit for detecting an error such as a short-circuit, a break in a load, and a temperature rise.

In particular, an intelligent power module (IPM) provided in each of the output modules 468 is a chip in the form of an integrated circuit, which is generally well known in the art and easily purchases a product having a desired function. It can be configured to include reverse voltage protection circuits, temperature limiting circuits, short circuit protection circuits and overcurrent protection circuits to detect errors in the module and protect the output module against faults including back EMF, short circuit, temperature rise and overcurrent. have. Accordingly, the network box can be protected from being broken by the load side failure.

The communication unit 462 is connected to the serial communication port of the operating room, that is, the control computer 424 of the fountain control computer 42 by a digital two-way communication line.

Preferred communication protocols in the present invention may be the DMX-512 protocol which is generally widely used in the field of lighting. The DMX-512 protocol, which was developed in 1986, continues to evolve to this day and can transmit data using, for example, RS-485 voltage levels. RS-486 was recently renamed EIA-486, but is widely known in the art as a method of transmitting a control signal as an electrical signal type. Such a communication method may use a universal asynchronous receiver / transmitter (UART), which is one of general-purpose circuits for serial communication, for example, and thus, a low-cost and reliable communication system may be constructed.

The network box according to the present invention is preferably configured to be operable between 9V and 60V as well as operating at 24V.

In this example, the network box uses the voltage level as a control signal, but there is always a possibility that this electrical signal may be distorted by noise generated from the inverter pump included in the fountain. Therefore, if noise can be a problem, such as when fountain components are to be intensively installed in a narrow space, the optical communication method has the advantage that the signal is typically noise resistant, and in recent years, inexpensive optical communication devices have been developed. Therefore, the optical communication method may be considered.

The first and second controllers 463 and 364 control the operation of the plurality of output modules 468 via the output buffer circuit 467 according to a control command received from the control computer 424 via the communication unit 462. As a result, each component of the fountain can be controlled. In addition, it is possible to control to receive the error information detected by each output module 468 and transmit it to the control computer 424 through the communication unit 462. When the present invention uses the DMX-512 protocol, since the protocol basically supports one-way communication, it is preferable to separate the control unit into two parts in order to improve the response speed compared to the protocol speed. That is, the control unit is responsible for the first control unit 63 of one microcontroller unit (MCU) that is in charge of control command reception and output module control, error data management and display, and transmission of error data to the control computer 424. The second control unit 64 of another MCU may be separated and configured.

In a preferred embodiment of the present invention, the network box 46 may further include a communication amplifier 469 that amplifies the control command signal received from the communication unit 462 and outputs it to the outside. The communication amplifier 469 may amplify and output the control signal received from the remote control computer 424 to the outside. This externally output control signal can be received by the communication unit of the other network box 47, and can provide an advantage that the control signal can be transmitted between a plurality of network boxes regardless of noise.

A fountain control system for controlling the components 222, 224, 226, 228 of a fountain installed in a reservoir, provided in accordance with the present invention, comprises a fountain control computer 42 and a network box 46.

The fountain control computer 42 is installed in an operating room remote from the reservoir and has a serial digital communication port for outputting control commands for controlling the operation of the components 222, 224, 226, 228 of the fountain. Computer 424 and power supply 422.

The network box 46 is installed in close proximity to the components 222, 224, 226, 228 of the fountain as described above and digitally connected to the communication unit 462 connected to the serial communication port of the control computer 424 of the operating room. Control operations of the fountain components 222, 224, 226, and 228, detect errors, and transmit the detected error information to the control computer 424, in accordance with control commands received through a bidirectional communication line of a. It is configured to.

One example of the control operation and the error detection operation performed in the network box is specifically illustrated in FIG. 4. In the example shown, the network box receives control commands from the control computer according to the DMX-512 protocol. When the first operation is started, the first control unit (MCU1, reception and control unit) and the second control unit (MCU2, display unit output and error data transmission unit) are initialized (511, 531), respectively. The first control unit stores a series of received control data including disconnection of the output module and checks for errors at the same time (512 to 517). When an error occurs in the received control data, the first control unit ( If MCU1) is initialized (511), but no error is found, the control command is transmitted to the output module (518). In general, since the DMX-512 protocol supports 512 channels per data link, if the counter exceeds 512, it is initialized again (519). At this time, for example, a request for error data may be checked and stored from the server computer system 45 that is remotely connected through the Internet (520). If there is a request, this information is passed to the second controller (521). The second control unit MCU2 receives the basic identification information from the first control unit after initialization and initializes the data. When the request is received from the server, the second control unit MCU2 receives the information from the first control unit and stores the information 532. For example, the second controller may display a company logo, an ID, a class of a network box, and the like on a display unit, which may be an LCD, and display the detected error data when there is detected error data (533). In addition, if there is requested data from the server, it can be operated to send it to the server (534).

According to another preferred embodiment, the fountain control system of the present invention may be provided with a plurality of fountain control computers 42 and / or may be provided with a plurality of network boxes 46.

For example, as shown in FIG. 3, when including a plurality of network boxes 46, 47, 48, 49, each network box amplifies a control command signal from the received control computer 424 to externally. It may further include a communication amplifier 469 that can be output to. One network box 46 is connected to the fountain control computer 42 via its communication unit 462, and the communication amplifier 469 of this network box 46 is connected to the communication unit of the next network box 47, The communication amplifier of this next network box 47 can also be connected to the communication section of the next network box 48. By this connection, a very large number of network boxes 46, 47, 48, 49 can be connected in turn, and receive control commands from the control computer 120. Accordingly, it is sufficient for the control computer 424 to connect a control line between one network box 46 and a control line connection between the other network boxes 47, 48, and 49 and the control computer 424. none. The result is a simpler wiring and easier installation and lower costs even when a complex system is required.

As another example, it is possible to include a plurality of fountain control computers 41, 42, 43, 44. Each fountain control computer 41, 42, 43, 44 can be connected to each other by means of a two-way data communication network 4, which can be, for example, an internet network. The internet network 4 may also be connected to a server system 45 for remote central management, for example operated by a fountain installation manufacturer. Each fountain control computer 41, 42, 43, 44 is then configured to transmit error data received from the network box connected thereto to the server system 45. Accordingly, the error status of each component of the final load stage, that is, the fountain, can be monitored by the remote server system 45 regardless of whether it is installed in the domestic or foreign countries via the Internet, and active after-sales service is based on this. The advantage of being possible can be provided.
