Description

The present invention relates to a design support system and a web server used when designing a low-voltage lighting system in which a plurality of low-voltage drive lighting fixtures are installed outdoors such as a garden.

For lighting systems installed outdoors such as in gardens, from the viewpoint of safety and workability, lighting fixtures that use LEDs that operate at low voltage as the light source are being used, and the light source is commercial. The AC power supplied from the power source is converted into DC power by the transformer and then supplied.

When designing a lighting system using the above-mentioned low-voltage drive luminaire (hereinafter referred to as "low-voltage lighting system"), it is necessary to consider the voltage drop due to the cord and the capacity of the transformer. Each of them will be briefly described below.

First, it is necessary to suppress the voltage drop due to the cord to a certain level or less. When a current is passed through the cord that connects the transformer and the luminaire, the voltage at the tip drops in proportion to the length of the cord. If the cord is long, the voltage drop will prevent sufficient current from flowing through the luminaire, reducing the illuminance of the light source. In order to avoid this, it is necessary to set the length of the cord so that the voltage applied to the luminaire does not fall below a constant voltage (for example, when the appropriate operating voltage is 12 [V], 11 [V]).

Second, it is necessary that the power consumption of the low-voltage lighting system (total power consumption of each luminaire) is less than the value obtained by multiplying the capacity of the transformer by a safety factor (for example, 70%). If the transformer is continuously operated with a value equal to or higher than the safety factor, the temperature of the transformer may rise and the output may stop. To avoid this, the power consumption of the lighting system must be less than the safety factor with respect to the allowable capacity of the transformer.

Therefore, the designer of the low-voltage lighting system must set the length of the cord and the capacity of the transformer so as to satisfy the above-mentioned two requirements for each design. Of these, the capacitance of the transformer can be calculated by a simple calculation, but for the voltage drop, it is necessary to understand the principle and master the calculation method.

However, this does not take advantage of the use of low-voltage driven luminaires, that is, the advantage of being able to design without a person who has sufficient knowledge of electricity, such as an electrician. Furthermore, since it is necessary to calculate the value of the voltage drop and the capacity of the transformer each time the design is performed, the design requires time and effort.

Hereinafter, the lighting design support system according to the embodiment of the present invention will be described with reference to the drawings.

Before explaining the configuration and operation of the lighting design support system (hereinafter, simply referred to as “design support system”) according to the present embodiment, the design support system of the present invention is used with reference to FIGS. 1 to 3. The wiring diagram of the low-voltage lighting system created will be described.

<Wiring diagram of low voltage lighting system>
FIG. 1 shows a wiring diagram of a low-voltage lighting system created by using the design support system of the present invention and displayed on a display of a user terminal.

The wiring diagram shows the product icons G1 to G7 (transformer G1, junction box G2, lighting fixtures G3 to G7) and the respective product icons G1 to G7 on the sketch (plan view) M of the garden where the low-voltage lighting system is planned to be installed. The code C connecting the wires is displayed in an overlapping manner, and a numerical value (unit: meter) indicating the length of the wiring is displayed on the code C. In addition, an image showing the appearance of the product is pasted in each frame of the product icons G1 to G7.

Of the sketch M, M1 shows the arrangement of plants and hedges, and M2 shows the layout of the building installed on the site. The transparency of the sketch M can be adjusted so as not to interfere with the design. Further, each product icon G1 to G7 is given a product number, and it is possible to create an estimate of the product necessary for constructing the low-voltage lighting system based on the data included in the wiring diagram.

As mentioned above, in the design of outdoor low voltage lighting systems, the voltage drop in the wiring cord is kept below a certain level, and the capacity of the transformer is kept above a certain level with respect to the power consumption of the lighting system. There is a need. The wiring diagram shown in FIG. 1 is also designed to meet these requirements.

First, a method of determining the length of the cord will be described with reference to the low-voltage lighting system 10 shown in FIG. In the low-voltage lighting system 10, the lighting fixture 13 is connected to the middle or the tip of the cord 12 pulled out from the transformer 11. When the plug 14 of the transformer 11 is connected to a commercial power outlet (not shown), the current of DC 12 [V] output from the transformer 11 is supplied to the lighting fixture 13 to perform lighting.

Generally, the voltage drop per 1 [m] of the code C when the luminaire 13 consumes 1 [W] of electric power is about 0.0025 [V]. As shown in FIG. 2, when the lighting fixture 13 having the power consumption A [W] is connected to the tip or the middle of the cord 12 having a length L [m], the voltage drop V generated by the cord 12 is calculated by the following equation (1). Is required by.
V = 0.0025 x L x ΣA --- (1)

In the graph of FIG. 3, the maximum length of the cord C for maintaining the voltage of the luminaire 13 connected to the tip or the middle of the cord 12 at DC11 [V] was calculated based on the above equation (1). It is a thing.

For example, in the configuration shown in FIG. 2A, when a lighting fixture 13 having a power consumption of 5 [W] is attached to the tip of the cord 12, if the length of the cord 12 is less than 80 [m], the lighting fixture 13 Since the voltage of can be maintained at 11 [V] or more, the brightness of the luminaire can be ensured.

On the other hand, in the configuration shown in FIG. 2B, when four lighting fixtures 13 having a power consumption of 5 [W] are attached to the cord 12, the total power consumption is 20 [W]. In order to maintain the voltage of the luminaire 13 at a distant position above 11 [V], the length of the cord 12 needs to be within 20 [m].

Next, how to obtain the capacity of the transformer 11 will be described. As described above, the capacity of the transformer needs to be set so that the total power consumption of each luminaire 13 is less than the value obtained by multiplying the capacity of the transformer by the safety factor. For example, when the safety factor is set to 70%, when the power consumption of the lighting system is 20 [W], it is necessary to use a transformer having a capacity of 28.6 [W] or more.

As will be described later, in the design support system according to the present embodiment, it is possible to easily confirm whether or not the cord C and the transformer G1 connecting the products shown in the wiring diagram of FIG. 1 satisfy the above requirements.

As described above, in the conventional design support system described in Patent Document 1, a sketch of the garden is separately prepared, a transformer and a lighting fixture are arranged on the sketch, and the length of the cord between each product is based on the sketch. Was calculated, and the user had to enter the value into the terminal.

On the other hand, in the design support system according to the present invention, an icon displaying the appearance of the product is placed on the sketch M of the garden prepared in advance by a drag-and-drop operation, and the product icon to be connected is placed with a mouse pointer or the like. Wiring between products is completed just by specifying using. Further, since the length of the cord connecting the products is calculated at the same time as the wiring, it is not necessary to separately calculate the length of the cord using the sketch. At the same time, it is determined whether or not the code C satisfies a certain requirement.

Further, in the design support system according to the present invention, when the arrangement of the lighting fixtures on the sketch is completed, it is determined whether the capacity of the transformer is appropriate for the value of the power used by the lighting system, and further, the wiring is completed. At this point, it is determined whether the voltage drop value in each code is appropriate.

If the capacity of the transformer does not meet the requirements, the transformer G1 is automatically changed to a transformer that meets the requirements. If the length of the cord connecting the products does not meet the requirements, it will be displayed on the screen, so the designer can proceed with the design while changing the type and arrangement of the lighting fixtures to meet the requirements. be able to.

As a result, by using the design support system according to the present invention, the designer selects a product while looking at the screen of the terminal and decides the arrangement, thereby creating a wiring diagram necessary for the construction of the low voltage lighting system. Therefore, it is possible to realize a significant improvement in the efficiency of the design work as compared with the conventional design support system.

<Configuration and function of design support system>
Next, the configuration of the design support system and the functions of each part according to the present embodiment will be described with reference to the block diagram of FIG.

FIG. 4 shows the configuration of the design support system 1 according to the present embodiment. The design support system 1 includes a web server 21 and an operator terminal 22 owned or managed by a business operator 2 that manufactures and sells lighting equipment, and a user terminal 3 used by a landscaping company or an exterior business operator involved in the design of a low-voltage lighting system. , And a wide area network (for example, the Internet) 4 that connects these devices in a mutually communicable state. Hereinafter, each member constituting the system will be described.

Web server software is installed on the web server 21, and a website 21a that supports the design of a low-voltage lighting system and a website 21b that contains catalog data of lighting equipment and accessories have been established. In designing the low voltage lighting system, the landscaping company or the exterior company accesses the websites 21a and 21b using the user terminal 3.

Although not shown, the web server 21 includes a processing means composed of a CPU and a storage means composed of a ROM, RAM, a hard disk, and the like. The processing means executes design support software stored in the storage means to calculate the voltage drop of the code and the power consumption of the lighting system. Further, the storage means stores the content data constituting the screen of the website 21a.

A database (hereinafter referred to as "DB") 23 that stores catalog data of lighting fixtures and peripheral members provided by the lighting fixture business operator 2 is connected to the web server 21. Further, the database management system software that controls the writing and reading of the DB 23 is pre-installed in the web server 21. When a landscaping company or an exterior company wants to confirm detailed information such as lighting equipment, the user terminal 3 is used to access the website 21b and read out the data stored in the DB 23.

The designer of the low-voltage lighting system accesses the website 21a using the user terminal 3, opens the design data input page described later, and inputs necessary data. The processing means (not shown) of the web server 21 calculates the value of the voltage drop generated in the code 12 by using the software for design support, and the graph of FIG. 2 (not shown) stored in the storage means (not shown). Alternatively, the graph created corresponding to the configuration of the lighting system) is read out to determine whether or not the operating voltage of the lighting equipment is within the appropriate range.

Further, the processing means (not shown) of the web server 21 calculates the power consumption of the lighting system, calculates the capacity of the transformer that meets the conditions from the value, and reads the data of the transformer that satisfies the requirement from the DB 23. And display it on the screen.

In the present embodiment, the web server 21 uses a server owned or managed by the lighting equipment business operator 2, but it does not necessarily have to be a server owned and managed by the business operator, such as a cloud server. You may use a rental server.

The operator terminal 22 used by the lighting equipment business operator 2 for managing the websites 21a and 21b is composed of a personal computer (hereinafter referred to as "PC"), and is a web browser software for browsing the web pages 21a and 21b. Is installed. The user terminal 3 used by the landscaping company and the exterior company is composed of a PC like the operator terminal 22, and the web browser software is installed in advance.

<Design procedure for low-voltage lighting system>
Next, when a landscaping company or an exterior business operator accesses the website 21a from the user terminal 3 to design a low-voltage lighting system with reference to the flowchart of FIG. 5 and the screen layout diagrams of FIGS. 6 to 23. The procedure of is explained.

First, the designer accesses the website 21a established by the lighting equipment business operator 2 via the user terminal 3 and the Internet 4 (step S11). In response to this, the web server 21 transmits the data of the design data input page to the user terminal 3 (step S21).

FIG. 6 shows the screen layout of the design data input page on the website 21a. The screen P1 on the left side of the page P is used for designing a low voltage lighting system and displays a wiring diagram of lighting fixtures arranged in a garden. Buttons B1 and B2 used at the time of design and a transformer product icon G1 are displayed in advance on the left screen P1.

On the other hand, the screen P2 on the right side is used when the designer reads out the sketch data from the storage means or searches for a product including a lighting fixture. Four tabs T1 to T4 are displayed on the right screen P2, and the headings of "background setting", "product search / planning", "environment setting / other", and "save / load" are shown in each tab. The designer opens the design data input page and proceeds with the design work while sequentially opening the tabs T1 to T4 on the screen P2 using the pointer.

First, the sketch of the garden is read and displayed as the background of the design screen P1 (step S12). Specifically, when the designer clicks the tab T1 of the "background setting" on the screen P2 using the pointer, the tab T1 opens, and the sub tabs T11 to T14 are displayed as shown in FIG.

The designer clicks the "reference" button on the sub-tab T11 using the pointer, reads out the sketch image file stored in the storage means (not shown) of the user terminal 3, and displays it on the screen P1. FIG. 8 shows a state in which the sketch M is displayed on the screen P1.

As described above, the sketch M shows the arrangement of vegetation, hedges, etc. planted in the garden, and a photograph of the actual garden taken from above may be used, or the position of the vegetation, etc. is actually measured and the position thereof is measured. Illustrations created based on the data may be used. As the sketch image file, a file created in any of JPEG, GIF, and BMP formats is used.

Next, the designer moves the sliders displayed on the sub tabs T12 and T13 to the left and right, and adjusts the size, the left and right, and the up and down positions so that the entire sketch M is displayed on the screen P1. FIG. 9 shows a sketch M whose size and position are adjusted in this way.

The transparency of the sketch M can be adjusted by using the slider of the sub tab T14. This is to make it possible to easily identify the product icon and the code from the sketch M when arranging the lighting equipment or the like on the sketch in the next step.

Next, the tab T2 of the "product search / planning" is opened, the product group stored in the DB 23 is searched, and the product to be installed in the garden is determined (step S13).

When the designer clicks the tab T2 of the "product search / planning" using the pointer, three windows W21, W22 and W23 are displayed on the screen as shown in FIG. The product search window W21 is provided with a form for entering search keywords and a search button. After entering the product name, etc. in the input form, clicking the search button will search for the icon at the bottom. The data of the finished product is displayed.

For example, when a "junction box" is entered in the input form and the search button is clicked, the data of the products classified into the "junction box" is read from the product group stored in the DB 23, and the window W21 is displayed as shown. The icon of the corresponding product is displayed. Data such as product code name, product number, and power consumption are also written on the icon as needed.

When the designer clicks the product icon using the pointer, detailed information on the product is read from the DB 23 and displayed in the window W22 as shown in FIG. The designer refers to the displayed information and decides the product to be installed in the garden. When the designer clicks the + mark displayed on the right side of the determined product icon, the product icon is displayed in the window W23 and registered as a product to be installed in the garden.

After repeating the above operation to determine the products to be installed in the garden, clicking the ">" mark displayed on the left bar of the windows W23 and W21 hides the windows W21 and W22, as shown in FIG. , Only the window W23 in which the icons of the registered products are listed is displayed.

Next, the products registered in this way are arranged on the sketch M displayed on the screen P1 and wiring between the products is performed (steps S14 and S23). The procedure of product arrangement and wiring will be described with reference to FIGS. 13 to 15.

First, as shown by the dashed arrow in FIG. 13, the designer moves the transformer product icon G1 to the position of the building M2 where the commercial power outlet is provided by the drag-and-drop operation. Hold in position.

Next, as shown in FIG. 14, the product icon displayed in the window W23 is moved to an arbitrary position in the sketch M by a drag-and-drop operation and held at that position. Of the product icons G2 to G7, G2 is a junction box for branching, and G3 to G7 are icons for lighting equipment.

In the process of arranging the product icon on the sketch M, the information of the product that has been arranged on the screen P1 is transmitted to the web server 21, and the processing means (not shown) of the web server 21 has the capacity of the transformer G1. , It is confirmed whether or not it is above a certain level with respect to the total power consumption of the arranged lighting fixtures (step S23).

When the capacity of the transformer G1 is less than a certain level, the processing means searches the DB 23 for a transformer that meets the requirements, and replaces the transformer displayed on the product icon G1 with a new transformer. In FIG. 14, the product icon G1 replaced with a new transformer is displayed.

After the placement of all the products on the screen P1 is completed, the pencil button B2 displayed on the upper left of the screen is clicked to switch from the product placement mode to the cord wiring mode. As shown in FIG. 15, when two product icons for which wiring is desired are specified by using the pointer, the icons are connected by the code C. In FIG. 15, the number “1” displayed on the code C is an initial value indicating the length of the code.

By the above procedure, the type and arrangement of the products constituting the low voltage lighting system are determined. FIG. 16 shows a state in which wiring is completed. In this state, the designer inquires of the web server 21 and confirms whether or not the voltage drop of each code C is below a certain level (step S23).

The designer clicks the tab T3 of "Preferences / Others" using the pointer, opens the sub-tab T31 of "Scale registration / Automatic wiring length input", and moves the slider left and right to move the slider to the left and right on the sketch M. The scale is adjusted so that the distance matches the scale of "1 m" displayed at the lower right of the screen P1. When the scale adjustment is completed, the length (unit meter) of the code C connecting the product items is displayed on the code as shown in FIG.

After the scale adjustment is completed, the data of the low voltage lighting system displayed on the screen P1, specifically, the data indicating the product number and the length of each code is transmitted from the user terminal 3 to the web server 21. , The value of the voltage drop of the code C is calculated.

The processing means (not shown) of the web server 21 that has received the code length and product number data reads the power consumption value of the corresponding lighting fixture from the data stored in the DB 23, and starts the design software. The value of the voltage drop in the code C is calculated, and it is determined whether or not the operating voltage of each luminaire is appropriate (11 V or more).

The value calculated in step S23 and the determination result are transmitted from the web server 21 to the user terminal 3. When the value of the voltage drop in the code C exceeds a predetermined value, as shown in FIG. 17, "A voltage drop has occurred" is displayed at the upper part of the screen P1, and the color of the corresponding code C is normal. It is shown in a different color from the code.

When the above display is displayed on the screen P1, the designer either brings the luminaire G7 closer to the luminaire G6 to shorten the length of the cord C, or replaces the luminaire G7 with one that consumes less power. In FIG. 17, the value of the voltage drop is increased by intentionally increasing the length of the cord, but the length of the longest cord that can be connected is displayed in the frame on the right side of the input form F. Therefore, the arrangement and type of the lighting equipment may be determined with reference to this value.

If you want to reduce the voltage drop value of code C by changing the arrangement of the lighting equipment, you can click the button B1 displayed on the upper left of the screen P1 to freely position the product icon by dragging and dropping. Can be changed to. As the position of the product icon changes, the length of the code displayed in the frame also changes.

Next, the procedure for burying a part of the cord in the ground will be described. In FIG. 18, since the ground surface of the junction box G2 and the lighting fixtures G4 and G5 is covered with tiles, it is necessary to bury the cord C in the ground with the cord C inserted into the protective pipe. In this case, when the "underground" button B4 of the input form F is clicked, the code C displayed on the screen P1 changes to a thick line, and it is displayed that the code C is inserted into the protective tube.

After the above work is completed, when the "Save / Load" tab T4 is clicked, the sub tabs T41 to T46 are displayed. When the designer clicks the sub-tab T41 of the "quotation display", the window W41 opens as shown in FIG. 19 and displays a list of the luminaires and peripheral members connected to the wiring diagram.

The list of windows W41 lists the part numbers, names, prices and quantities of all the products required for the low voltage lighting system, as well as the total price. In order to construct a low-voltage lighting system, not only lighting equipment but also wiring members (dry cones) and the above-mentioned protective tubes are required, but in the list, the data of these peripheral members are also read from DB23. It will be published and posted.

The designer makes a final confirmation of the wiring diagram displayed on the screen P1 and the products listed in the list (step S15), and if it is determined that a change is necessary (Yes in step S16), the product search and the product search The product placement and wiring are redone (steps S13 and 14).

Since the lengths of the cords sold by lighting equipment companies are limited (for example, 5 m, 15 m, 50 m, etc.), the types of cords that can realize the cord length shown in the wiring diagram by combination are shown in the list. And the quantity are displayed.

In addition, the cord length displayed in the wiring diagram is the length when the lighting fixtures etc. placed in the garden are connected by a straight line, and it is easier to handle if it is made a little longer, so if necessary , Select a slightly longer code. Furthermore, if you have already obtained the lighting fixtures and cords on the list, delete these fixtures and members from the list.

After completing a series of operations including the design change (No in step S16), the designer who wishes to issue the quotation requests the web server 21 to issue the quotation (step S17).

Specifically, the designer clicks the "Download Quotation" button displayed at the bottom of the window W41 in FIG. The web server 21 creates a quotation based on the data of the list displayed in the window W41 and transmits it to the user terminal 3.

FIG. 20 shows the quotation ES transmitted to the user terminal 3. The quotation ES includes the product number, product name, quantity, unit price and total price of all the products necessary for constructing the low-voltage lighting system displayed on the screen P1. If the designer prints the quotation ES displayed on the screen and places an order with the lighting equipment company, all the members necessary for constructing the low-voltage lighting system can be prepared.

By using the design support system according to the present embodiment, it is possible to easily obtain a wiring diagram and a subassembly diagram of constituent members required for construction of a low-voltage lighting system. The method of obtaining the wiring diagram and the substructure diagram will be described below.

When the designer wishes to obtain the wiring diagram, he / she requests the web server 21 to create the wiring diagram by using the user terminal 3 (step S18). Specifically, the designer clicks the sub-tab T42 of the “print display” on the screen P2 of FIG. The web server 21 requested to create the wiring diagram deletes unnecessary information from the wiring diagram displayed on the screen P1, adds the product numbers of the product icons G1 to G, and displays the wiring diagram WD shown in FIG. 21. Create and send the data to the user terminal.

The wiring diagram WD shows the layout of the lighting fixtures on the sketch of the garden, so if you print this out and give it to the contractor, the contractor will install the lighting fixtures in the garden based on the wiring diagram. You can wire the cord. As a result, the efficiency of construction can be greatly improved.

Further, when the designer checks the sub-tab T43 of the “wiring diagram night display” shown in FIG. 19, as shown in FIG. 22, by illuminating the product icon with the emission color of the lighting equipment, the lighting state at night A wiring diagram that simulates is created. Although it is simple, the effect of lighting can be confirmed by the wiring diagram of FIG.

Next, when the designer wishes to obtain the small assembly drawing, he / she clicks the sub-tab T44 of the "small assembly drawing download" on the screen P2 of FIG. The sub-assembly diagram shows an image showing the appearance of the product and the main specifications, and is created for each of the lighting fixture and the peripheral member and stored in the DB 23 in advance.
