Check if it is registered.

Thus, when the registration of the ID code is confirmed, the display data is sent to the next data discriminating / processing means 24 to decode the display data, but if there is no registration, the subsequent signal processing is ignored.

In the signal processing in the data discrimination / processing means 24, the display position signal and the display control signal included in the display data are decoded, and the decoded display position signal and display control signal are displayed in the display means 25.
Display window provided in the display unit 2
The display window designated by the display position signal from among 2a to 2h is turned on or off by the display control signal. Here, since the display data transmitted from the wireless individual transmitter 1 does not include the turn-off signal, the display type selecting means
If the blinking mode described later by 26 is not set, the display window is not turned off.

FIG. 5 (a) shows an external view of one embodiment of the display unit 2, without providing an extra peripheral frame so that a plurality of display units 2 can be assembled vertically and horizontally adjacent to each other. It has a simple shape with four upper and lower internal lighting display windows 2a to 2h having display lamps inside.

Such display windows 2a to 2h of the display unit 2 have [1]
A translucent seal (not shown) having numbers such as [8] is attached and used.

Further, FIG. 5 (b) shows various changeover switches provided on the back surface of the display unit 2, 21a is a changeover switch for switching and setting the above-mentioned registration mode and display mode, and 21b is a changeover mode. Monitor lamp that flashes when setting, 2
1c is a registration deletion mode (which will be described later) that automatically deletes the registered ID code each time the transmission data sent from the wireless transmitter is received, and a changeover switch that switches and sets the display mode. 21b is the registration deletion mode. The monitor lamp, 21e, which blinks during setting, is a monitor lamp that lights up each time the display unit receives a wireless signal.
In order to monitor the operation of the display unit, when the display unit 2 receives the demodulated signal from the receiving unit 3, the light e is turned on regardless of whether the ID code is registered. 21f is the ID registered in the system data registration means 22
It is a reset switch for all erasing that is operated when erasing all codes at once. Therefore, when the switch 21f is operated to be reset, the ID codes registered in the system data registration means 22 are erased all at once, so that the additional registration mode changeover switch 21a is operated at the time of additional registration.

Further, the display unit 2 sends a registration confirmation signal of the ID code to the notification unit 5 when the registration of the ID code of the transmission data received from the reception unit 3 via the notification unit 5 is confirmed. Can be output (see the configuration in Fig. 8), and 21g and 21h are switches for setting the registration confirmation sound at that time, and the ringing sound when the display window is turned on or off can be set. There is. In addition, 21i
Is a selection switch for blinking, turning on / off, and a timer mode of the display type selection means, and the timer mode can set the set time into two types, a long set time and a short set time. .

FIG. 6 shows a format of transmission data transmitted from the wireless transmitter.

One frame of transmission data consists of pre-receive followed by 32-bit data. The 32-bit data consists of a 19-bit ID code consisting of upper bits H18 to H9 and lower bits H8 to H0. It is divided into two bit groups, a bit P1 for parity check of ID code (H18 to H0) is provided between both bit groups, and a bit P1 which is the inverted parity bit P1 is provided as a synchronization bit after that. Similarly, between the data group including the ID code and the display data, the parity bit P2 of the display data is similarly provided, and the bit P2, which is the inverted parity bit, is provided as the synchronization bit after that. .

The display data has a structure in which a display position signal and a display control signal are combined, and the display control signal is composed of a lighting signal or a non-lighting signal.

The preliminary data is provided to give the wireless call display system an additional function. As shown here, when the synchronization bit is provided as a bit obtained by inverting the parity bit of the data, the parity bit is used as a reference even if there is an unknown bit in the group of data. Since the bit can be identified, there is an advantage that the occurrence of errors can be reduced even when the communication conditions are poor.

7a to 7c show an example of use of the wireless call display system of the present invention.

FIG. 7a shows an example in which the wireless individual transmitter 1 is combined with the reception unit 3, the notification unit 5, and the display unit 2, and is used in a coffee shop or a restaurant.
When m3 operates the transmission switch 1a of the wireless individual transmitter 1 installed on the table T, the call is lit and displayed on the display unit 2 installed near the waitress ma.

When configuring such a system, the wireless individual transmitters 1 installed on each table are operated by operating the window position setting switches 1b and 1c (see FIG. 2b).
The display windows 2a to 2h of the display unit 2 are designated in advance, the mode setting switch 21a of the display unit 2 is operated to set the registration mode, the ID code of each wireless individual transmitter 1 is registered, and then the mode setting switch is set. Operate 21a to switch to the display mode for use.

Further, in such a system, when a call is made, a timer mode can be selected in which the display window of the display unit 2 is turned on for a predetermined time and then automatically turned off. The selection switch 21i of the display type control means provided on the unit 2 side is switched to the timer mode (see FIG. 5 (b)). In addition, the waitress ma who received the call goes to the table T where the customer m3 who called after completing the requirements, operates the transmission switch 1a of the wireless individual transmitter 1 again, and lights the display window of the display unit 2. Can be turned off. In this case, when the operation of the transmission switch 1a of the same wireless transmitter 1 is repeated, it is necessary to alternately invert the display window from on to off. Is the selection switch 21 of the display type control means 26 provided on the display unit 2 side.
The i is switched to the blinking mode (see FIG. 5 (b)).

Figure 7b shows two wireless central transmitters 4 (1), 4
This shows an example in which (2) is combined with the receiving unit 3, the notification unit 5, and the display unit 2, and is used in a coffee shop, a kitchen of a restaurant, or the like.
It shows an example used for information transmission when ordering and delivering food with mc.

When the cook mc cooks, the wireless central transmitter 4 (1) installed on the cook mc side is operated to light up the order number on the display unit 2 and the waiter mc confirms that the cook is ready. Operate the wireless central transmitter 4 (2) installed on the mc side to turn off the display.

When configuring such a system, the lighting / lighting-off mode is selected, and the control type selection switch of the display unit 2 is selected.
21i is set on the timer side (see Fig. 5 (b)), and the central wireless transmitter 4 (1) is installed on the cock mc side.
Is only for lighting, the control switch 40i is on the lighting side, while the wireless central oscillator 4 (2) installed on the waiter mc side is for turning off only, so the control switching switch 40i is set to the off side. (See FIG. 3 (b)).

FIG. 7c shows a wireless individual transmitter 1, a wireless central transmitter 4, a receiving unit 3, an alarm unit 5, and a display unit 2.
This is an example of a combination of and, and shows an example used when a maid me manages the reception of a customer in a restaurant or the like having a plurality of individual rooms R.

In the individual room R, the wireless individual transmitter 1 is installed on the table T ', and the wireless central transmitter 4, the receiving unit 3, the notification unit 5, and the display unit 2 are installed at the entrance or the like.

When the customer md in the individual room R operates the transmission switch 1a of the wireless individual transmitter 1 to make a call, the display window of the display unit 2 is illuminated and the notification unit 5 outputs a ringing sound. When the reception is completed, the central wireless transmitter 4 is operated from the side of the maid me at the entrance to turn off the light.

When configuring such a system, each individual room R
Wireless individual transmitter 1 installed on table T'of
Is operated by operating the window position setting switches 1b and 1c.
Although the display window of the display unit 2 is designated, the wireless central oscillator 4 is exclusively turned off, so the control changeover switch 40i
Switch to the light-off side (see Figures 2b and 3b).

Next, a display unit incorporating various additional functions used in the system of the present invention will be described.

FIG. 8 shows the configuration of the internal circuit of the call display unit of the present invention in which a registration deletion mode is added in addition to the registration mode and these are provided with a holding function by a timer.

The basic configuration is the same as that of FIG. 4, but the operation mode switching means 21 has a configuration in which changeover switches 21a and 21c for selectively setting the registration mode and the registration deletion mode and a holding timer 21A are added. There is. Therefore, in this basic timer holding function, when the changeover switches 21a and 21c are operated to set the registration mode and the registration deletion mode, the monitor lamps 21b and 21c
d flashes, the registration mode and the registration deletion mode are continued for the time set by the timer 21A, and after the set time, the mode automatically shifts to the display mode without operating the changeover switches 21a, 21c. . In this case, it goes without saying that the set mode can be released by operating the changeover switches 21a and 21c during the set time.

Further, in the registration mode, as described above, the ID code is sequentially registered in the system data registration means 22 by simply operating the transmission switches 1a, 4a ... Of the wireless transmitters 1 and 4, In the registration deletion mode, operate the transmission switches 1a, 4a ... of the wireless transmitters 1 and 4,
If the transmission data is transmitted, the system data registration means 22
ID codes registered in are deleted one after another.

In such an ID code registration / registration deletion mode, every time transmission data is received and registered, the designated display window of the registered transmission data lights up to complete the registration / registration deletion mode. Then, the display window that has been turned on is turned off.

Further, 30 is a notification sound output means for making the notification unit 5 sound when the registration of the ID code is confirmed, and the notification signal output means 30A and the notification sound setting means for setting the notification sound at this time. It is composed of 30B. The setting of the notification sound is performed by operating the changeover switches 21g and 21h (see FIG. 5B) of the display unit 2.

The display position memory 28 is used for the display window of the display unit 2 when the blinking mode is selected by the display type selecting means 26.
This is for determining the lighting state of 2a to 2h.
It has an address corresponding to 2h, and when any of the display windows 2a to 2h is turned on, the flag is set to the address corresponding to the turned on display window, and when the display window is turned off, the corresponding address is turned on. Flag is reset. The timer circuit 27 is used in a timer mode described later and has a holding timer.

FIG. 9 is a flowchart showing a control operation procedure in the display unit having a retrigger holding function in the registration mode and the registration deletion mode.
1001 → 1007 is the basic control operation of registration mode, 1008 →
1014 shows the basic control operation in the registration deletion mode.

When the registration mode is selected, within the set time,
If you receive the transmission data that the ID code is not registered,
After the ID code is registered in the system data registration means 22, the timer 21A is re-triggered and the set time returns to the beginning to continue the registration mode. Automatically returns to.
Also, when the registration deletion mode is set, if the ID code registered transmission data is received within the set time, the timer 21A is retriggered after the ID code is deleted and the set time is set. Returning to the beginning, the registration deletion mode is continuously performed, and when the set time elapses, the display mode is automatically restored as well.

Such a retrigger operation is particularly convenient when the number of wireless transmitters to be registered is large and the system scale is large, or when a person who is unfamiliar with the operation registers and deletes.

Further, FIG. 10 shows the control operation in each mode of blinking, lighting / extinguishing, and timer selectable by the display type selecting means 26.

After the display position signal and the display control signal included in the display data extracted from the transmission data whose ID code has been confirmed to be registered by the data discriminating / processing means 24, the control mode is entered.

In each mode, a flag is set (set) at the corresponding address of the display position memory 28 when the display windows 2a to 2h are turned on, and a flag is set (set) at the corresponding address of the display position memory 28 when the display windows 2a to 2h are turned off. Although it is possible to monitor the lighting state of the display windows 2a to 2h by performing the operation of clearing (resetting) the flag, such a display position memory 28
The method of setting and resetting the flag is not always necessary except the blinking mode, and may be omitted.

Steps 2004 → 2011 are in lighting / flashing mode, Steps 2012
→ 2019 shows the control procedure in the blinking mode, and step 2020 → 2030 shows the control procedure in the timer mode.

In the timer mode, the timer is retriggered when the lighting signal is received again while the display windows 2a to 2h are lit, and the lighting is lit continuously for the set time. Further, the turn-off signal is not processed in the blinking mode and the timer mode, and even in the timer mode, the turn-off signal is not processed when the display window is turned on (see step 2031 prohibited act).

Next, a display unit in which the lighting mode of the display window is different will be described.

FIG. 11 shows a main part configuration of a display window of the display unit which is configured by using a 7-segment display element instead of the internally illuminated lamp.

In this display unit 2, two 7-segment display elements are combined in each display window so that a two-digit number from 00 to 99 can be displayed. Instead of such a number display, another The pattern may be variably displayed.

Further, according to the call display system as shown in the figure, the transmission data transmitted from each wireless transmitter 1 and 4 needs to include a display pattern for displaying numbers from 00 to 99. The wireless individual transmitter 1 provided with the transmission switch 1a can set a display pattern in which a number is designated instead of the display position signal, and the wireless central transmitter 4 can set the display signal for each transmission switch 40a. However, the setting of such a display pattern can be easily handled by providing another setting switch.

Also, in such a system, regarding the display signal,
The position of the display window is not fixed, and each time transmission data is received, it is displayed sequentially from the beginning of the empty display window.Therefore, it is extracted from the transmission data whose ID code registration has been confirmed. When the display control signal is a lighting signal, the display signals are sequentially written from the head side of the vacant address of the display data memory 28A, and when the display control signal is a lighting signal, the display signal stored at that address is erased. After that, the display signal written to the next address is sequentially moved to and compensated for in the empty address thus generated. In this way, the display means (not shown) reads the display signal stored in the display data memory 28A, which changes each time new transmission data is received, and selectively lights two 7-segments for display. It is displayed so that there is no empty display window in the middle of the number display of the signal.

FIG. 11a shows a display control operation in such a display unit with a time chart. Steps 3004 → 3013 are operation in lighting / off mode, Steps 3014 → 3023 are operations in blinking mode, Steps 3024 → 30
34 shows the operation in the timer mode, respectively.

FIG. 12 is a format configuration diagram of transmission data used in such a system, and is composed of 32 bits as in FIG. FIG. 13 shows the address arrangement (memory map) of the display data memory for the display unit 2 having eight display windows.

The example of FIG. 14 shows the display pattern included in the transmission data transmitted from the wireless transmitters 1 and 4 so that the display pattern can be displayed up to twice as many as the eight display windows 2a to 2h of the display unit 2. For this reason, the display windows 2a to 2h have a two-layer structure of a front surface display and a rear surface display, and these can be switched alternately for display.

A first display data memory 28B is provided for the front display of the display windows 2a to 2h, and a second display data memory 28B is provided for the back display of the display windows.
The display data memory 28C is provided.

The transmission data whose ID code registration has been confirmed is sent to the display control signal discrimination circuit 24B and the display data discrimination circuit 24C constituting the data discrimination / processing means 24, where the display control signal and the display pattern are extracted. In the data processing circuit 24A, the thus-taken display pattern is sent to the first or second display data memory 28B, 28C for writing or erasing.

In this system, when the display pattern is only in the first display data memory 28B, only the front surface display is performed, and the back surface display is performed when the display pattern written in the first display data memory 28B is full. Both are used and are alternately displayed at predetermined time intervals.

Therefore, even one display unit has eight display windows 2a ...
A call display that is twice as long as 2h can be displayed, enabling effective use without increasing the size of the display unit.

Further, the first and second display data memories 28B and 28C have addresses corresponding to the display windows 2a to 2h of the display unit 2, and the addresses from the leading side in the order in which the decoded display signals are received. When the display pattern is written to all addresses of the first display data memory 28B sequentially, the second data is written next.
Is sequentially written from the first address side of the display data memory 28C, and after the display pattern written to any address of the first and second display data memories 28B and 28C is erased, the address is changed to The display patterns written in the subsequent addresses are sequentially transferred to and updated in the addresses on the leading side so as to compensate.

That is, in this display unit, the data processing circuit 24A displays a lighting display when the display control signal attached to the display pattern extracted by the display control signal determination circuit 24B and the display data determination circuit 24C is a lighting signal. Output a control signal and write the display pattern to an empty address of the first or second display data memory 28B, 28C. If the display control signal attached to the display pattern is a light-off signal, turn-off display control A signal is output to erase the display pattern from the corresponding address in the first or second display data memory 28B, 28C.

In the data processing circuit 24A, the display pattern extracted each time the transmission data is received in this manner is written or erased in the first or second display data memory 28B, 28C, and then the first display data is deleted. The display pattern written in the memory 28B is read, a drive signal is sent to the display means (not shown), and the display pattern is decoded by the display means,
Display data memory 28 in the display windows 20a to 20h of the display unit 2
The display pattern read from B, 28C is lit and displayed.

Thus, each time the transmission data for calling display is transmitted from the wireless transmitters 1 and 4, the display data memory 28
The display patterns written in B and 28C are updated, and as a result, the display patterns are always shifted and packed in the display windows 20a to 20h of the display unit 2 from the display window on the front side.

FIG. 15 shows a configuration diagram of a signal format of transmission data in the case of performing the two-layer display, which is basically the same as that shown in FIG. In addition, FIG. 16 shows
The memory map of the second display data memories 28B and 28C is shown, and it can be seen that each memory is provided with addresses corresponding to the eight display windows 20a to 20h.

FIG. 17 shows an example of the control operation of the display unit 2 in the case of performing the two-layer display in the blinking mode. Steps 4000 → 4004 are for switching between front and back display of the display window, and steps 4046 → 4070 are for The control is performed while checking whether or not the display signal is written in the second display data memory.

Further, in the blinking mode, since the extinguishing signal is not used for the display control signal, the prohibiting process 4045 is performed, and the extinguishing signal is not processed.

The reference numeral 4000 → 4044 in FIG. 18 shows the control operation procedure in the lighting / extinguishing mode, and FIG. 19 shows the control operation procedure in the timer mode (see steps 4000 → 4025).

In the timer mode, when the display control signal designating the same display window is received while the display window of the display unit 2 is lit, the retrigger operation of returning the reset timer setting time to the initial setting and resetting it. Are doing.

In the above example, the mode in which the display unit is displayed on the front and back sides with one display unit has been shown, but a display window formed by connecting a plurality of display units may be layer-displayed. In this case, It is more convenient if the notification unit is used to notify the switching of the display surface.

FIG. 20 shows a main configuration of a display unit divided into a parent display unit and a child display unit when a plurality of display units are connected and used.

In such a system, the parent display unit 2A has an internal function similar to that of the display unit 2 shown in FIG. 4 and FIG. 8 in order to have a function of registering an ID code and decoding received transmission data. In addition to the circuit, the first and second display data memories 28D and 28E corresponding to all the display windows 20a to 20h constituting the system including the parent and child display units, and the processed display pattern to the child display unit 2B. ... including a serial conversion circuit 29 for sending to the side, each of the child display unit 2B does not have a determination function like the parent display unit 2A,
A decoder circuit 20k for receiving a display pattern sent from the parent display unit 2A and a display means (not shown) are provided and stored in the first and second display data memories 28D and 28E of the parent display unit 2A. Display patterns other than those displayed on the display window 20 of the parent display unit 2A are displayed on each display window.
It has only the function to display on 20, 20.

Further, in this display system, in order to perform two-layer display on the front and back sides, the parent display unit 2A stores the first and second display data memories 28D, which store the display patterns displayed on the respective display layers. 28E is provided, and the first display data memory 28D
When the display pattern stored in is full, the received pattern is sequentially written into the second display data memory 28E from the head address. It goes without saying that all of the above-mentioned display modes can be implemented in such a call display system.

21 a) and b) are parent display units when two child display units 2B are connected to one parent display unit 2A.
First and second display data memories 28D and 28E provided in 2A
It shows the memory map of the display signal displayed in the display window of the parent display unit 2A in the single digit address including 00, and the first stage child display unit 2B in the address of the 10th generation.
The display pattern displayed in the (No.1) display window is stored, and the 20th address has a second sub display unit.
The display pattern displayed in the 2B (No. 2) display window is written.

Further, FIG. 22 shows another example of the call display system configured by combining the parent display unit with the child display unit, and shows only the configuration of the part different from that shown in FIG.

Also in this system, like the example shown in FIG. 20,
A serial conversion circuit 29 is provided on the parent display unit 2A 'side, and the display pattern in which the registration of the ID code is confirmed on the parent display unit 2A' side is once written in the display data memory (not shown). Read out, serial conversion circuit 29
Is transmitted to the child display unit 2B '... through the signal line lS, and on the child display unit 2B' side, it is decoded by the decoder circuit 20k to perform lighting display on each display window 20. However, the display means (not shown) provided in the child display unit 2B 'is such that the first first stage 2B' (No. 1) is driven by the drive signal sent from the parent display unit 2A 'via the signal line l. It is driven, but the second and subsequent stages are 2B '...
(No.2, 3) is transmitted to the next stage side one after another by the signal line 1 wired across the child display units 2B '...
The wiring is such that it reaches the final stage child display unit 2B '(No. 3) and is returned to the parent display unit 2A' again.

Therefore, when the display signals stored in the first display data memory (not shown) provided on the parent display unit 2A 'side are sequentially read, the display means of the parent display unit 2A' is first driven to display the parent display. The window 20 is turned on, and then the display pattern is sent from the serial conversion circuit 29 to the sub display unit 2B '... Side, but the sub display unit 2B' ... The drive signal to each display means is a signal. Since they are sequentially supplied through the line 1, the first and second sub-display units 2B '(N
After all the display windows 20 of o.1) and 2B '(No. 2) are turned on, the drive signal is also supplied to the display means of the sub display unit 2B' (No. 3) in the final stage.

Then, when all the display windows 20 of the final stage child display unit 2B ′ (No. 3) are turned on, the parent display unit 2A ′ side is
Since the signal is returned via the signal line 1, the data processing circuit 24A on the side of the parent display unit 2A 'detects this state and reads the second display data memory (not shown), In this manner, the call display is performed by sequentially driving from the child display unit 2B 'side closer to the parent display unit 2A'.

FIG. 23 is a time chart showing the operation procedure when three parent display units 2B 'are connected to one parent display unit 2A'. The initial stage child display unit 2B 'is shown.
It can be seen that, after all the display windows of (No. 1) are turned on, the second and third child display units 2B ′ (No. 2) and 2B ′ (No. 2) are turned on sequentially. With such a configuration, the display means of the child display unit, which does not require the lighting of the display window, is not driven, so that energy saving of the entire system can be achieved.
