Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, for example, is a so-called distributed system having a plurality of slave control units each having a DIP switch for setting a function and sharing control functions, and a master control unit for integrally controlling the slave control units. The present invention relates to a control type vending machine (also abbreviated as a vending machine) having a function of displaying a setting state of a DIP switch. In the following figures, the same reference numerals indicate the same or corresponding parts.

2. Description of the Related Art FIG. 5 shows a configuration example of a control circuit of the present invention and a conventional fraction control type vending machine. In the figure, 01 is a master control unit (also abbreviated as master), 02 (02A-02)
N) is a slave control unit (also abbreviated as slave), and 03 is a communication line connecting the master 01 and each slave 02A-02N. Here, 02A is a slave (also called a keyboard slave) that shares control of the keyboard, and 02B is a product unloading mechanism not shown in the figure (thus various motors, solenoids, etc.).
It is assumed that the slave is a slave (referred to as a carry-out slave) that takes charge of the control. The master 01 communicates with each of the slaves 02A to 02N via the communication line 03, and causes each slave to perform its control.

By the way, each slave 02 is provided with a DIP switch for setting its function. Figure 6
Shows a specific example of the setting function of the dip switch on the carry-out slave 02B in the cup type vending machine. In this example, there are four dip switches (abbreviated as SW) from SWA to SWD. Each of these DIP switches is provided with 8 individual switches (for 8 bits). The various functions shown in FIG. 6 are set according to whether each individual switch is turned on or off.

[0004]

However, the vending machine as described above has the following problems. Since the control box (slave) 02 is divided by function, it is often arranged near the load that is the target of the control function. In such a case, there may be a case where the setting and checking of the DIP switch cannot be easily performed. The DIP switch is small in shape and difficult to set and check. The number of DIP switches on the hardware is limited (not unlimited). Therefore, even if the number of functions increases, it is not possible to easily add setting items correspondingly. In addition, adding a setting item with a DIP switch increases the cost. Therefore, the present invention can solve this problem. An object is to provide a vending machine with a switch setting display function.

[0005]

In order to solve the above-mentioned problems, the vending machine according to claim 1 is switched to either an on state or an off state based on an operation, and no further operation is performed. As long as it has a plurality of switches (such as individual switches of DIP switches) that hold the same state, and switch data storage means that stores the on or off state of each switch as setting data, this setting data enables function setting In a vending machine to be performed, means for displaying the on / off state of the switch (keyboard 1
Key 3, liquid crystal display screen 2, etc.),

According to another aspect of the present invention, the vending machine has a plurality of switches (individual dip switches, each of which is switched to an on state or an off state based on an operation, and maintains the same state unless a subsequent operation is performed. Switch, etc.) and a switch data storage means for storing the on or off state of each switch as setting data, and in the vending machine in which the setting is carried out by the setting data,
Means for displaying the on / off state of this switch on the screen while omitting the switch and assuming that this switch is present (memorization code input keys 3B, 3A, etc.)
And a means for switching the on / off state of the switch on the display screen (item switch 12, number keys 3A, setting key 3B, etc.), and the on / off state of each switch corresponding to the switched screen. Is stored in the switch data storage means in place of the previous storage data (master 01, communication line 03, etc.).

[0007]

In the invention according to claim 1, the setting state of the DIP switch is displayed on the screen. In the invention according to claim 2, the DIP switch is omitted, and instead, the setting data is set and input using the screen displaying the DIP switch.

[0008]

Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is an explanatory diagram of the invention according to claim 1, and FIG. 1C shows a configuration example of the keyboard 1 controlled by the above-mentioned keyboard slave 02A, and 2 indicates a liquid crystal display screen on the keyboard 1 and 3 ( 3A to 3E) are keys. Here, 3A is a number key, 3B, 3C, 3
D is a setting key, an end key, and a clear key as function keys. 3E is a cursor movement key. 1A and 1B are examples of the DIP switch setting state display screen 11. Here, (A) of the figure shows the setting state of the DIP switch A (SWA) on the carry-out slave 02B, and (B) of the same figure also shows the DIP switch B.
The setting state of (SWB) is shown. Here, SWA,
SWB numbers 1 to 8 for individual switches ON and O
The black side of the square corresponding to the FF represents the set state.

In such a screen, by performing a predetermined operation on the key 3 on the keyboard 1, the master 01 requests the carry-out slave 02B to send data indicating the setting state of the DIP switch. Then, the data is displayed by being transmitted in the route of the transport slave 02B → master 01 → keyboard slave 02A. The setting screen takes into consideration the actual shape of the DIP switches and the arrangement order of the individual switches.

FIG. 2 shows an example of ON / OFF states of eight individual switches of the DIP switch A and their setting data (8 bits). In this case, ON of the individual switch is "1" and OFF is "0". This setting data is stored in a predetermined memory area in the slave (in this case, carry-out slave 02B).

3 and 4 are explanatory views of the invention according to claim 2. The present invention eliminates the dip switch on the slave and enables the setting of slave dip switch setting items on the keyboard. That is, FIG. 3 shows an example of a display screen on the keyboard 1. Here, 11 is a screen of the setting state of the DIP switch A, 12 is a screen of a switch (also referred to as an item switch) for designating a setting item of the DIP switch A, and 13 is a lamp for displaying the selection of the item switch 12. It is a screen. These 11, 12,
It is assumed that the screens of 13 are integrally displayed as shown in FIG.

FIG. 4 shows the key operation contents and the corresponding screen in the invention according to claim 2 in the order of operation steps. Referring to FIG. 4, first, in a step, a personal identification code is input. That is, in this example, after pressing the setting key 3B on the keyboard 1, the numeral keys 3A "1", "2", "3", "4" are sequentially pressed. Then, the screen as shown in FIG. 3 is displayed on the liquid crystal display screen 2. Here, all eight individual steps of the DIP switch A are set to the ON side. Next, this DIP switch A
When it is desired to change the setting of, for example, to change the setting of the individual switch of number 3, the number 3 of the item switch screen 12 is pressed as in step. Then item step screen 1
The lamp screen 13 corresponding to the "number 3" of 2 is switched to the lit (black-painted) display as shown in FIG.

In the next step, the numeral key 3A "0" and the setting key 3B are pressed in order to set the individual switch number 3 to OFF. Then, the lighting display of the lamp screen 13 moves to "number 4" of the individual switch so that the next individual switch can be set. In the next step, if the end key 3C is pressed to end the setting, the screen display returns to the standby screen. The setting data of the DIP switch A thus set and input is the keyboard slave 02A →
The data is transmitted from the master 01 to the carry-out slave 02B and set and stored in the carry-out slave. Although the item switch screen 12 is used for designating the individual switch of the DIP switch in FIG. 3, a cursor may be used instead.

[0014]

According to the invention of claim 1, since the setting state of the DIP switch on the slave is displayed on the display screen of the keyboard, it is possible to easily confirm the setting state of the DIP switch. According to the invention of claim 2, the dip switch on the slave is omitted, the dip switch is displayed on the display screen of the keyboard, the setting is performed on the screen, and the setting data is sent to the slave to store the setting. By doing so, it is possible to reduce the cost by omitting the DIP switch hardware, and eliminate the inconvenience of setting the DIP switch.
Further, it is possible to easily cope with an increase in setting items.
