Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable wireless device such as a wrist-worn type or a card type which displays received information, and more specifically, a portable wireless device which performs incoming call alert processing by a vibrator when transmission data is received. Regarding the device.

[0002]

2. Description of the Related Art As a portable radio apparatus of this type, there is one described in Japanese Patent Laid-Open No. 7-87540. This conventional portable wireless device includes a control unit, an incoming call notification unit based on vibration of a vibrator, and a drive unit. In this portable radio device, when the control unit detects an incoming call, it outputs a signal for intermittent driving to the vibrator to the driving unit. Then, the drive unit intermittently drives the vibrator based on the signal from the control unit. Thus, in the conventional portable wireless device, during the incoming call notification operation, by repeating the operation and the operation pause of the vibrator alternately, it is possible to prevent the voltage drop of the battery during the incoming call notification operation,
It is possible to obtain stable operation and reception performance.

[0003]

However, this conventional portable radio apparatus has the following problems. That is,
70 mA typical when the vibrator is operating
Since a current of -100 mA flows, the battery voltage may drop and the receiver may not operate normally. In addition, the noise caused by the ground current when the vibrator vibrates and the noise of the high frequency component caused by the vibration of the vibrator flow into the receiver, resulting in a deterioration of the data error rate and a substantial decrease in the reception sensitivity. It may end up. In this case, it may be possible to stop the operation of the receiving unit while the vibrator is being driven intermittently. However, for example, a POC in which a data string addressed to its own station is continuously transmitted
When communicating using the SAG (hereinafter referred to as "Pokusag") method, etc., the first data string addressed to the own station can be received, but if the vibrator is driven, the subsequent data string addressed to the own station will be received. The other problem is that you can't do it. In addition, in such a communication method, it is generally specified that the transmission pause time is provided after transmitting once, so that if the data sequence transmitted first cannot be received, the data sequence is transmitted next. I don't know what time it will be. Therefore, the user of the portable wireless device also has a problem that the data string cannot be received quickly.
On the other hand, if the vibrator is driven after receiving all the received data, there arises a problem that the data to be quarreled cannot be quickly transmitted.

The present invention has been made in view of such a problem. Even when the transmission data addressed to the own station is continuously transmitted, a quick incoming call alert process is performed and all the transmission data are transmitted. An object of the present invention is to provide a portable wireless device that can be reliably received.

[0005]

In order to achieve the above object, a portable wireless device according to claim 1 is configured by connecting a plurality of data blocks including a plurality of data strings respectively associated with device numbers. Receiving unit for receiving the transmitted data, a storage unit for storing the own station device number, and a reception control for controlling the intermittent reception of the receiving unit according to a communication procedure for causing the receiving unit to receive the data string associated with the own station device number. Unit and an incoming call alert processing unit that performs incoming call alert processing by vibration of the vibrator by intermittently outputting a vibrator drive signal when a data string for the own station device number is received by the receiving unit The incoming call alert processing unit is a wireless device for use when the receiving unit receives transmission data including a data string corresponding to the own station device number. Receiver the signal control unit and outputting a vibrator driving signal when being inactive control.

In this portable radio apparatus, for example, when a plurality of data strings addressed to the own station apparatus number are continuously transmitted as in the so-called poxag method, the reception control section is associated with the own station apparatus number. The receiving unit performs intermittent reception control according to a communication procedure for causing the receiving unit to receive the data string.
On the other hand, when the receiving unit receives the data string for the own station device number, the incoming call alert processing unit suspends the operation of the receiving unit by the reception control unit while receiving the transmission data including the data string. Only when the vibrator drive signal is output. As a result, the vibrator operates intermittently. In this way, since the vibrator does not operate during the receiving operation of the receiving unit, malfunction of the receiving unit and occurrence of data error due to noise caused by battery voltage drop and operation of the vibrator are prevented, and as a result, the receiving unit is continuously operated. The data string addressed to the own station can be surely fetched. Also,
Since the transmitter side can continuously transmit the data string to the same station, the data can be transmitted to the portable wireless device very quickly.

According to a second aspect of the present invention, there is provided the portable radio apparatus according to the first aspect, wherein each data block is transmitted at a constant cycle, and the incoming call alert processing unit is synchronized with the constant cycle. It is characterized in that the incoming call warning process is executed by outputting a vibrator drive signal.

In this portable radio apparatus, the incoming call warning processing section outputs the vibrator drive signal almost in synchronism with a constant cycle of the repeatedly transmitted data string. As a result, since the vibrator vibrates in a substantially constant cycle, the user can surely know the incoming call warning by the regular vibration.

According to a third aspect of the present invention, there is provided a portable radio device according to the second aspect, wherein the incoming call alert processing section is
When the receiving unit receives new transmission data during the incoming call alert processing, the incoming call alert processing is temporarily stopped, and the incoming call alert processing is restarted almost in synchronization with a fixed cycle of the received new outgoing data. And

For example, when the user does not stop the operation of the vibrator and the incoming call alert processing by the incoming call alert processing unit is continued, the output timing of the vibrator drive signal by the incoming call alert processing unit and new transmission data are displayed. The operation timing of the reception unit by the reception control unit for reception does not always match. Even in this case,
In this portable wireless device, the incoming call warning processing unit temporarily stops the incoming call warning process when the receiving unit receives new transmission data. Then, the reception control unit causes the reception unit to intermittently receive according to the communication means. After this, the incoming call alert processing unit
The incoming call warning process is executed again in synchronism with a fixed cycle of new transmission data received. As a result, the receiving unit can reliably receive the data string addressed to itself in the new transmission data.

A portable radio device according to a fourth aspect is the portable radio device according to the second or third aspect, wherein the data block is configured to include a synchronization signal for data reception, and the incoming call alert processing unit is configured to perform the synchronization signal. The warning process is executed in synchronization with the above.

In this portable radio apparatus, the incoming call alert processing section can drive the vibrator periodically by outputting the vibrator drive signal in synchronization with the synchronization signal of the data block. Further, even when new transmission data is received, by synchronizing the vibrator drive signal with the synchronization signal, the vibrator drive signal can be always output without overlapping with the reception control signal.

The portable radio apparatus according to claim 5 is the portable radio apparatus according to any one of claims 1 to 4,
The transmission data is configured by the Pokusag method that includes eight data strings in one data block, and the storage unit stores at least a data string that is not associated with the own station device number in one data block as the own station device number. The apparatus is characterized by storing three consecutive device numbers.

In this portable wireless device, for example, assuming that the data block includes a data string having a data string number 0 to 7 associated with the device number, three consecutive data strings are addressed to each portable wireless device. In the case where the incoming call alert processing unit is transmitted to the incoming call alert processing unit, the storage unit stores the device numbers associated with 0 to 5 as the own station number.
It is possible to output a vibrator drive signal that is periodic and preferable as an incoming call alert. In other words, in the poxag method, eight 1 / 8-second data strings (frame data) form one block data (batch data), so three consecutive frame data are addressed to each portable wireless device. If the local station number is set to 0 to 5, the one block data always has three consecutive empty data strings. Therefore, if the vibrator drive signal is output while the empty data sequence is transmitted, it is possible to cause vibrator vibration with a duty ratio of 3: 5, which is vibration that the incoming call warning is easy for the user to understand.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a portable radio apparatus according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a portable wireless device 1 which is a so-called pager. The portable wireless device 1 is attached to a user's wrist and used for communication in a specific small premises such as a pachinko parlor, a hospital, or a theater,
In particular, it has extremely effective reception performance when data is continuously transmitted to the same portable wireless device 1.

The portable radio device 1 includes a slot antenna 1
1, reception unit 12, control unit (reception control unit, incoming call alert processing unit) 13, ROM (storage unit) 14, RAM 15, liquid crystal panel 16, liquid crystal panel drive circuit 17, power supply control circuit 1
8, a vibrator 19, a vibrator drive circuit 20, a mode switch 21 and a set switch 22.

The receiving unit 12 is an FM receiver that receives a single conversion frequency of 430 MHz band, demodulates a radio signal incident through the antenna 11 by intermittent reception, and demodulates the received data into the control unit 13. Output to. The receiving unit 12 may be configured by the double conversion method or the direct conversion method.
The control unit 13 is configured by a one-chip microcomputer and is used for the intermittent reception control process of the receiving unit 12 and the vibrator 1
Various processes including the intermittent drive control process of 9 are executed. The ROM 14 stores an operation program of the control unit 13, an ID number (own station device number) predetermined for each portable wireless device 1, and the like. In this case, as the ID number, a number is used so that the frame numbers of the transmission data configured according to the poxag method are associated with 0 to 5, as described later. The RAM 15 temporarily stores the received data transferred by the controller 13. The liquid crystal panel 16 displays the day of the week, the time of day, the presence / absence of battery capacity, the operating states of the receiver 12 and the vibrator 19, received data, and the like. The liquid crystal panel drive circuit 17 drives the liquid crystal panel 16 based on the display signal output from the control unit 13. The power supply control circuit 18 intermittently outputs power to the receiving unit 12 according to the power supply control signal output from the control unit 13. The vibrator 19 vibrates according to a vibrator drive signal output via the control unit 13 and the vibrator drive circuit 20, and transmits that there is received data addressed to itself. The mode switch 21 is used to switch the contents displayed on the liquid crystal panel 16 when there are a plurality of received data, and to designate various modes such as designation of hours and minutes at the time adjustment. The set switch 22 stops the operation of the vibrator 19 and sets the internal clock at the time and minute designated at the time adjustment.

Next, an outline of the operation of the portable radio device 1 will be described. The portable wireless device 1 receives various data in the transmission data when the ID number of its own station is transmitted by the Pokusag method. Specifically, the control unit 13
Intermittently outputs a power supply control signal to the power supply control circuit 18 to cause the power supply control circuit 18 to output power to the reception unit 12, thereby causing the reception unit 12 to perform intermittent reception. On the other hand, when a preamble signal is transmitted from a transmitter (not shown), the control unit 13 detects this and causes the receiving unit 12 to continuously receive. After this, the control unit 13
The receiving unit 12 is made to receive the data addressed to the own station of a predetermined frame number among a plurality of frame data (data string) transmitted following the preamble signal. This frame data contains the ID of the portable wireless device 1 to be called.
The information graphic data for displaying the numbers and the matters to be informed to the user on the liquid crystal panel 16 by graphics are included. The control unit 13 compares the received ID number with its own ID number stored in the ROM 14, and when they match, stores the information graphic data in the RAM 15. Thereafter, the control unit 13 outputs a vibrator drive signal to the vibrator drive circuit 20 to intermittently drive the vibrator 19, and causes the liquid crystal panel 16 to display an information graphic corresponding to the information graphic data based on the information graphic data.

Next, the structure of transmission data in the communication system including the portable radio apparatus 1 will be described with reference to FIG. As shown in the upper part of the figure, the portable wireless device 1 is configured to be able to receive the transmission data by the poxag method. In this example, the transmission rate is 512 bps
It is. Further, the transmission data by the poxag method is composed of a preamble signal 31, transmission ID data 32, a SYNC signal 33, and a plurality of frame data 34, 34, ....

The preamble signal 31 is used to synchronize the phase of the data reading clock of the receiver 12 with the transmission rate of the transmission data, and the entire transmission time is (1 + 1/8) seconds. ing. The transmission ID data 32 represents the device number of the transmitter that is transmitting the data, and has a transmission time of 1/8 second. SY
The NC signal 33 is used to synchronize the phase of the data reading clock with the phase of the frame data 34, 34 ... Or to synchronize with the output of the vibrator drive signal, and the transmission time is 1/16 seconds. Has been done. Each frame data 34, 34 ... Has two 32-bit codewords (CW) and has a transmission time of 1/8 second. Further, the code word is 1-bit data arranged from the beginning of the data for indicating whether it is ID number data or normal data, 20-bit normal data, and 10-bit error correction data, 1-bit parity check data. Further, the frame data 34 is associated with the ID number in advance. Specifically, the ID number is the value 8
It is determined that the frame data 34 of the frame number corresponding to the remainder divided by is the transmission data addressed to the portable wireless device 1 of the ID number. The frame data 34 addressed to each portable wireless device 1 is not necessarily limited to one frame, but a plurality of continuous frame data 34, 34.
.. can be transmitted to one portable wireless device 1, and in this embodiment, three consecutive frame data 3 are transmitted.
.. are transmitted to the portable wireless device 1 as an example. In addition, the SYNC signal 33
. And 7 pieces of frame data 34, 34 .. constitute one set of batch data (block data),
The transmission data that is transmitted once has a transmission time of (1
It is configured to include the first, second and third batch data of 7/16) seconds.

Next, a communication procedure for receiving this transmission data will be described. First, the outline is explained. In the Pokusag method used in a small campus, the transmission time of one transmission data is about 5 seconds from the viewpoint of effective use of radio waves,
It is predetermined to provide a transmission pause time of at least 1 second when one transmission is completed. Therefore, the control unit 13 cannot predict the transmission time of the transmission data to be received next after the transmission suspension time. Therefore, the control unit 13 operates the receiving unit 12 every one second and surely receives the preamble signal 31 at the beginning of the transmission data, thereby detecting that the transmission data is being transmitted. Then, the control unit 13 takes in the frame data addressed to itself by the intermittent reception control process.

Next, regarding the intermittent reception control process of the receiving unit 12 and the intermittent drive process of the vibrator 19 by the control unit 13, the ID number of the portable radio apparatus 1 is "1000."
The case of "8" will be described as an example with reference to FIGS.
The frame number of the frame data 34 associated with this ID number is “0”.

As shown in the middle part of FIG. 2, the control section 13 outputs a power supply control signal 41a (hereinafter, referred to as "power supply control signal 41" when no distinction is made) to thereby receive the reception section 12a.
Drive. In this case, when the reception unit 12 receives the preamble signal 31, the control unit 13 continuously outputs the power supply control signal, and the reception unit 12 transmits the transmission ID data 32 and SYN.
Frame number 0 associated with C signal 33 and own station
The frame data 34 is continuously received. In this case, the own station ID is added to the frame data 34 of frame number 0.
When the number is included, it is determined that the data is the transmission data addressed to the own station, and the power supply control signal is continuously output, and the subsequent frame data 34 and 34 of the frame numbers 1 and 2
To receive continuously. Then, the control unit 13 stops the output of the power supply control signal 41a and then 1/8 second later (SY
4/8 seconds after the fall of the NC signal 33), the vibrator drive signals 42 and 42 having a duty ratio of 6:11 and a pulse width of 3/8 seconds are supplied to the vibrator drive circuit 20 as shown in the lower part of the figure. Output periodically. In this case, the pulse width is set to the above-mentioned time because the SYNC signal 33
The total time of the eight frame data 34, 34 ... Is 17/16 seconds, and considering the voltage recovery of the air battery (not shown) used in the portable wireless device 1, the vibrator 19 is turned on. / OFF duty ratio is 6:11
And a ratio of about 3: 5 is preferable, and
This is because the warning due to the vibration of the vibrator when the portable wireless device 1 is carried is easy to understand. If necessary, the control unit 13 also generates display data based on the content of the frame data 34 and outputs the display data to the liquid crystal panel drive circuit 17.
As a result, the liquid crystal panel 16 displays an information graphic that graphically represents the matter to be transmitted to the user.

Next, the control unit 13 outputs the power supply control signal 41b 1/8 seconds after the output of the vibrator drive signal 42 is stopped and outputs the SY signal in the second batch data.
The receiving unit 12 is caused to receive the NC signal 33 and the frame data 34, 34, 34 of the frame numbers 0, 1, 2. After that, the above processing is repeated by outputting the power supply control signal 41c, and the control unit 13 instructs the receiving unit 12 to
The frame data 34 addressed to its own station in the first to third batch data in one transmission data is received three times. In addition,
The control unit 13 periodically outputs the power supply control signal 41 to output S
By monitoring whether or not the YNC signal 33 is transmitted, it is possible to capture all the frame data 34 addressed to the own station even when four or more batch data continue. In this example, since the SYNC signal 33 cannot be received when the power supply control signal 41d is output, the control unit 13 determines that the transmission of the transmission data has ended, and terminates the intermittent reception control process for this transmission data. Subsequently, the vibrator drive signal 42 is output in the same cycle to intermittently drive the vibrator 19.

Next, when the user operates the set switch 22 and the mode switch 21, the control unit 13 stops the output of the vibrator drive signal 42 and the vibrator 1
The vibration of 9 is stopped. On the other hand, when the user does not operate these switches 22 and 21, the vibrator 19 is continuously driven. In this case, when the transmission data is transmitted again, since there is usually no correlation between the transmission data already received and the new transmission data, the output timing of the vibrator drive signal 42 and the new transmission data are transmitted. The output timing of the power supply control signal 41 for receiving the frame data 34 of the incoming transmission data does not match, and the vibrator drive signal 42 is output within the time when the power supply control signal 41 should be output. Therefore,
When the control unit 13 outputs the vibrator drive signal 42 prior to the output of the power supply control signal 41e that is output 1 second after the output of the power supply control signal 41d is stopped, after stopping the output, The power supply control signal 41e is output. This makes it possible to capture new transmission data. After that, the control unit 13 outputs the vibrator drive signal 42 in the same cycle as the cycle described above, regardless of whether or not the transmission data is transmitted to the own station. In this case, the output timing of the vibrator drive signal 42 is 4 / after the SYNC signal 33 taken in by turning on the power supply control signal 41e ends.
8 seconds later. As described above, by calculating the transmission time from the SYNC signal 33 as a reference and outputting the vibrator drive signal 42, it is possible to reliably control the reception time and the vibration time. This is because the timing of outputting the power supply control signal 41 to receive the frame data 34 addressed to itself is also based on the SYNC signal 33. FIG. 3 shows the relationship between the power supply control signal 41 and the vibrator drive signal 42 when receiving this new transmission data. Note that, as shown in the figure, this processing shortens the pulse width of the vibrator drive signal 42a, and the time interval between the vibrator drive signal 42a and the vibrator drive signal 42 to be output next is the same as the normal output cycle. Although different, it does not make the user feel uncomfortable.

As described above, according to this embodiment, the control section 13 controls the power supply control signal 41 and the vibrator drive signal 4 to be different.
2 and 2 are output so as not to overlap each other. As a result, even when the frame data 34 addressed to the own station exists among the three batch data in the Pokusag method, after the vibrator 19 is rapidly driven based on the first frame data 34 addressed to the own station. , The subsequent two frame data 34, 34 can be reliably received.
As a result, the information to be transmitted to the user of the portable wireless device 1 can be extremely quickly and efficiently performed in the Pokusag method in which only a limited amount of information can be transmitted. Further, since the vibrator 19 can be vibrated periodically, the user can be surely notified of the incoming call warning.

In the present embodiment, the pulse width of the vibrator drive signal is set to 3/8 seconds, but it is not limited to this and can be set to any time. For example, if only three batch data are continuous as in the present embodiment, the output timing of the power supply control signal 41 and the output timing of the vibrator drive signal 42 do not deviate so much, and therefore, simply from 3/8 seconds to 4 / It can be set up to 8 seconds. However, when the pulse width is made longer than the pulse width in the present embodiment by using the poxag method, the output cycle of the vibrator drive signal 42 cannot always be made constant in relation to the batch data transmission time, or Depending on the type of battery used, the upper limit value may be limited in relation to the battery voltage recovery time. Further, the vibrator drive signal 42 can be output twice or more within the cycle of one batch data. However, it is needless to say that extremely shortening the pulse width of the vibrator drive signal 42 is not preferable for ensuring the transmission of the incoming call warning.

Further, in this embodiment, the output stop time (1/8 second) of both signals is provided between the vibrator drive signal 42 and the power supply control signal 41, but it is not always necessary and both signals are overlapped. It is also possible to output continuously so as not to become. In this embodiment, when the ID number is "10008", the vibrator drive signal 41 having a pulse width equal to the transmission time of the three frame data 34, 34, 34 of the frame numbers 0, 1, 2 is the frame. The numbers 4, 5 and 6 are output in the same time frame as the time when they are sent, but in such a case, the output stop time between both signals is not provided.

When the ID number is "10013", the associated frame number is "5".
The vibrator 19 can be vibrated when the frame data 34 of the frame numbers 0 to 4 is transmitted. Therefore, the control unit 13 outputs the power supply control signal 41 and the vibrator drive signal 42 as shown in FIG. Specifically, when the control unit 13 outputs the power supply control signal 41f and receives the first SYNC signal 33, the power supply control signal 4 is generated.
Stop the output of 1f. Next, the control unit 13 outputs 5/8
After the lapse of seconds, the power supply control signal 41g is output again, and it is determined whether or not the frame data 34 of frame number 5 includes transmission data addressed to the own station. When determining that there is transmission data addressed to the own station, the control unit 13 receives the frame data 34 and 34 of the frame numbers 6 and 7 and the SYNC signal 33, and then
The output of the power supply control signal 41g is stopped. Next, the control unit 13 outputs the vibrator drive signal 42b having a pulse width of 3/8 seconds when 1/8 seconds have elapsed after the output of the power supply control signal 41g was stopped. This is frame number 1, 2, 3
This is for vibrating the vibrator 19 within the transmission time of, and even in this case, the receiving operation of the receiving unit 12 and the vibration of the vibrator 19 do not overlap. After that, the control unit 13 alternately outputs the power supply control signal 41 and the vibrator drive signal 42. Since the SYNC signal 33 does not exist when the control unit 13 outputs the power supply control signal 41h, the control unit 13 determines that the transmission data has ended, stops the output of the power supply control signal 41h, and then restarts the power supply when 1 second elapses. Control signal 41i
Is output. In this case, at the timing of outputting the vibrator drive signal 42c, the control unit 13 stops the output. When it is determined that there is transmission data when the power supply control signal 41 is output, the control unit 13 determines that the SYNC signal 3
3 is detected, the vibrator drive signal 42 is output when 1/8 seconds has elapsed from the fall in synchronization with the SYNC signal 33, and then the power supply control signal 4 is output as described above.
1 and the vibrator drive signal 42 are alternately output. Also in this case, both signals 41 and 42 do not overlap.

As described above, when assigning ID numbers to a plurality of portable wireless devices 1 in a communication system using three consecutive frame data 34 with one data,
By using the ID number such that the frame number corresponding to the ID number is 0 to 5, the control unit 13 controls both signals 4
It is possible to periodically vibrate the vibrator 19 with a duty ratio of 3: 5 without superimposing 1, 42. As a specific ID number, for example, "10008",
"10009", "10010", "10011",
If “10012” and “10013” are used, these ID numbers correspond to frame numbers 0 to 5, respectively. Therefore, since there are at least three consecutive empty frame data 34 in one batch data, the vibrator drive signal 42 can be periodically output within the time when these are transmitted.

Further, the reception stop time is set to 1 second because the preamble signal 31 is defined as (1 + 1/8 second). However, in the case of other communication methods, it may be set longer or shorter than that. You can Even in such a case, as long as the data reading clock of the control unit 13 and the preamble signal 31 are synchronized, the frame data 34 addressed to the own station can be surely fetched.

[0033]

As described above, in the portable radio apparatus according to the present invention, since the vibrator does not operate during the receiving operation of the receiving section, the battery voltage drops due to the operation of the vibrator and the occurrence of data error due to noise occurs. Since this is prevented, even if the data strings addressed to the own station device are continuous, it is possible to perform a prompt incoming call warning process and to reliably capture these data strings. Further, since the vibrator can be vibrated in a substantially constant cycle, the user can surely know the incoming call warning by the regular vibration. further,
When the incoming call alert processing unit receives new transmission data by the receiving unit, the incoming call alerting process is temporarily stopped, and then the incoming call alerting process is executed again almost in synchronization with the constant cycle of the new incoming transmission data received. Therefore, the receiving unit can reliably receive the data string addressed to itself in the new transmission data. Further, by synchronizing the vibrator drive signal with the synchronization signal, the vibrator drive signal can be periodically output without being superposed on the reception control signal. Furthermore, the incoming call alert processing unit stores the device number in which the storage unit stores at least three consecutive data strings that do not include the data string associated with the local device number.
It is possible to output a vibrator drive signal that is periodic and preferable as an incoming call alert.
