Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a selective call receiver with 1 display function.

[Conventional technology]

In recent years, this type of selective call receiver with display function has become available.

With the remarkable development of circuit technology and semiconductor device technology, miniaturization, weight reduction, multifunctionality, and lower power consumption are being realized. Currently, in addition to being used for individual calls for the original purpose, message information services that transmit messages by transmitting message information and displaying the message information on a display attached to the receiver are becoming widespread. be.

[Problem that the invention seeks to solve]

This message information service is for example stocks.

There are examples where it is used for gold market prices, etc.

Since prices are constantly being displayed, changes in prices cannot be noticed unless they are displayed periodically, and there is a possibility that the subscriber may miss the value he or she wants to know.

Also, since this type of message is stored in the receiver's internal memory and displayed at any time, there may be a discrepancy between the memorized value and the displayed value, even if the value you want to know is in the memory. , there was a drawback that it was not possible to know when it was received.

Therefore, in the present invention, the subscriber can set the information that the subscriber has in advance on the selective calling receiver with the display function that the subscriber wants to make the sound sound, and the judgment value (for example, when a certain stock price exceeds a certain amount, the sound will sound). By optionally inputting "Sound", the subscriber does not have to worry about the display until the sound is heard, and also has the function of always being able to obtain the latest information because the sound sounds when the necessary information is received. The present invention aims to provide a multifunctional selective call receiver with a display function.

[Means for Solving the Problems] According to the present invention, means for storing a message signal containing a judgment value desired by the subscriber in the selective calling signal of the first self; A selection device with a display function, characterized in that it has means for receiving a message signal following the selection call signal, comparing the message signal with the stored judgment value, and displaying a ringing sound if the conditions are met. A paging receiver is obtained.

In addition, according to the present invention, means for receiving a message signal subsequent to the first self-selective calling signal and emitting a sound, and displaying the message signal on a display, and a second self-selective calling signal. means for storing a message signal containing a judgment value desired by the subscriber following the signal; and a third means for receiving the message signal subsequent to the selective calling signal of the subscriber, and storing the message signal and the stored judgment value. A selective calling receiver with a display function is obtained, which is characterized in that it has means for comparing and displaying a ringing sound if the conditions are met.

This determination will be explained in detail later in the flowchart. .

FIG. 1 is a block diagram of one embodiment of a selective call receiver according to the present invention.

A radio signal received by the antenna 1 is amplified and demodulated by the radio section 2. The demodulated signal is sent to the CPU 5 (Central Processor) by the waveform shaping circuit 3.
The waveform is shaped into a waveform that can be input to (ingUnit). C.P.
U5 is.

P-ROM4 (Programmable-Read
It compares its own selective calling number pre-written in the 0nly Memory) with the signal coming from the waveform shaping circuit 3, and if they are the same, it supplies a ringing signal to the driver 7 to notify it that there is a call. , the sound is emitted from the speaker 8. In addition, P-ROM4 has A call and B call.

A plurality of selective call numbers such as C call etc. are written. Further, the CPU 5 reads the message information signal following the 1 selection call signal, and displays the message information signal on the LCD 6 (Liquid
(Crystal Display) to provide visual information. The reset switch 9 is connected to the CPU 5 and performs operations such as stopping the sound, stopping the display on the LCD 6, and starting up the LCD 6. The crystal oscillator 10 is used to generate a synchronous clock signal in the CPU 5.

FIG. 3 shows an example of the configuration of two CPUs used in the present invention.

Program memory 501 is used to store programs necessary to operate the one-select call receiver. The program is sent step by step to the control section 503 by the program counter 502.

With this content, the control section 503 sends control signals to each section within the CPU S. The program counter 502 is.

Each time the control unit 503 receives such an instruction from the program memory 501, one step is added, but the step may jump depending on five instructions. The data bus 508 and external circuits are interfaced by input/output ports 504 to 507. The output port 5o4 outputs a sound signal to the driver 7, and the input port 505 inputs signals from the waveform shaping circuit 3 and reset switch 9. Out capo) 506 is,
A read control signal is output to the P-ROM 4, and the input port 507 reads data from the P-ROM 4.

The data bus 508 also connects the program counter 502
+ ALU 511 (Arithmetic an
d Logic Unit) r Accumulator 510
．． It is also connected to a data memory 509 and transfers data. Here, the data memory 509 is used as a flag, message information memory, work area, etc.

As will be described later, in the data memory 509, for convenience, the message information memories are divided into M1, M2, . . . corresponding to the input message information. .

A synchronizing clock signal necessary for inputting a signal from the waveform shaping circuit 3 to the input port 505 is generated by two oscillation units 513. Crystal oscillator 10. generated by timer 512. LCD
The driver 514 is for displaying specific message information stored in the data memory 509 on the LCD 6.

The operation of the receiver after receiving the 1 selection paging signal will be described in detail with reference to the flowcharts in FIGS. 4(a), (b), (c), and (d).

First, let's talk about the normal call flow with a message.
This will be explained using Figure (a). In this embodiment, the A call is used. From the call waiting state 400, it is determined in step 401 whether the reset switch has been pressed, and if it has been pressed, the process jumps to FIG. 4(a).

Referring to FIG. 4(d), it is determined in step 440 whether there is data in the data memory 509, and if there is data, it is displayed in Stella f441. Furthermore, step 442 sets a timer and counts until the timeout (
443) and timeout.

Stop the display (444) and return to the L call waiting state 400.

On the other hand, if it is not reset, referring to FIG. 4(,) again, if the selective calling number stored in the P-ROM 4 matches the selective calling number of the received signal, step
Assuming that a call is received at step 2, it is determined whether the call is an A call (4, 03). In case of A call, Stetsuno 4
At step 04, the message reception operation is performed, 1 is displayed (405), and sound A is started (406).When the reset switch 9 is pressed at step 407, 1 is displayed and sound A is stopped (408).
)L, returns to the initial state, call waiting state 400.

Next, C is used for data input to make comparative judgments on the message information sent as an information service.
The call will be explained using FIG. 4(b).

When the call is received and it is determined in steps 403 to 405 that it is a C call, N is reset to 0' in the counter in the program memory 501 (406)L.

In step 407, the following flow is continued until the counter N becomes ゛2''.In other words, add 1 to the counter N and (408) 1. After receiving the word (409) +7), the MSB
The content of the 3-bit content judgment flag is "100".

If the message information Il of the Tsumashi C call is (4
10) In step 411, the message information is stored in Ml of the data memory 509.

The counter K is increased by +1 and the process returns to step 407. If the content determination flag is not "100", it is similarly determined in step 412 whether or not it is the message information module 2 of the "101" call. At the same time, the counter K is increased by +4, and step 407
Return to

If the content judgment flag is neither ``100'' nor ``101'' (D), the message information text B i? - error display stops and the subscriber enters a call waiting state 400.

Also, in step 407, it is determined whether N=2, and the above flow is performed again, and if N=2, and then=5.
When 11 is stored in Ml and I2 is stored in M2 of the data memory 509, step 41 is executed.
The contents are displayed in step 9 and the process jumps to the ringing sound B in step 415. If it is 5 in step 418, 1.
It can be assumed that the message information of ``00' or filol'' has been changed twice, so an error display 414 is displayed.

Through the above flow, C call message information ■1
- Even if the order of I2 is the same for each subscriber.

The data is correctly stored in the data memory 509 of the CPU 5.

Is this state when new message information is entered?

Retains until power is removed or removed. If the data format does not match or an error occurs, the subscriber will have to enter it again over the phone.

Finally, when a B call for the message information service is received, a flow that compares the data entered in advance in the C call with the data for the information service and sounds only if the desired conditions are met. This will be explained using FIG. 4(C).

First, when a B call is received (404) in FIG. llB call message information I,
If it is different, it is in call waiting state 40.
Return to 0. If the content judgment flag is "100", the message information is stored in the data memory 5090M3 (422), the next one word is received (423)L, and the content judgment flag is checked to see if it is message information I2 of "101#". (424), and in the same way as above, if it is different,
Clear M3 of data memory 509 and call waiting state 4
Return to 00. If the content determination flag is '101#', the message information I2 is stored in M4 of the data memory 509 (426), and the next one word is received in step 427.

Similarly, if the content judgment flag is not '110'', M3 and M4 in the data memory 509 are erased, and the process returns to the call waiting state 400.If the content judgment flag is '110', the message information I3 is read as data. M of memory 509
5 in the data memory 509 in step 430.
The contents of step 3 and message information processing 1 are input into the achievator 510. If the contents of Ml in the data memory 509 and the message information module 1 are the same, then in this embodiment, it means that the brand recently received matches the desired brand entered by the subscriber, and the size is changed. Proceed to the judgment flow.

If they do not match, the process returns to the call waiting state 400. The flow for determining the size of the accumulator 5 is performed in step 432.
Input the contents I2 of M4 of the data memory 509 into 10,
If the 4th bit from the MSB is II 11+, the MSB
If the message information of the information service from the 5th bit is smaller than the message information I2 of the C call set by the subscriber in FIG. 4(c), 1 is displayed (43
5), performs a ringing sound (436). This continues until the reset switch 9 is pressed (437), and when it is pressed, the beep 2
The display stops and returns to the call waiting state 400. Similarly to the above flow, if the 4th bit from the MSB is 0#, go to Stella f434, and if the content set by the reverse subscriber is smaller than the information service content, a tone 1 will be displayed in steps 434 to 436. When the reset switch 9 is reset, the display of the sound 1 is stopped and the state returns to the call waiting state 400.

In addition, if you want to display the contents of the data memory during a B call, the display will not ring even if the call is received.

Since the contents are stored in a data memo, they can be displayed by pressing the reset switch.

An example of sounds A, B, and C is shown in FIG. Here the CPU
5 to the driver 7, the intermittent pricking period or the intermittent pricking ratio is changed for each tool.

This concludes the explanation of the flowchart in this embodiment.

In this embodiment, only two types of cases were described: when the value exceeds one judgment value and when the value falls below the judgment value.

This can be easily carried out even when the values are equal, or when the value is smaller or larger than one judgment value.

Also, if the sound is controlled based on match or mismatch, it may be two characters.

〔Effect of the invention〕

From the above explanation, 2. According to the present invention, in a message information service where a lot of information such as stock and gold market prices is constantly distributed, a subscriber can store an arbitrary amount, etc. in a selective call receiver with a display function. By comparing the information with the message information service, it is possible to make the sound sound under desired conditions. This has the effect that subscribers do not have to think about when the information they want will be broadcast, they do not have to regularly check the contents of the service, and they are freed from the constraints of receivers. ,・
