Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information receiving apparatus for receiving regularly provided information such as stock price information and various market price information.

[0002]

2. Description of the Related Art Currently, a service for providing information such as stock prices using a wireless paging system is being implemented. In this type of information providing service, each information receiving device is set with a selective call number corresponding to the information that the information receiving device is about to receive or the company that provides the information. When a plurality of types of provided information with a code are added to the selective calling number and transmitted, on the other hand, each information receiving device matches the received selective calling number with its own preset selective calling number, It is configured to receive the provision information added to the selective call number.

In this type of information providing service, however, each piece of information is periodically provided with the latest information at a predetermined time interval, and each information receiving device has a memory capable of storing a plurality of pieces of received information. When the information is received, the information is displayed and simultaneously stored in the memory so that the information can be read out and displayed later as needed.

[0004]

However, in the information receiver provided with the memory as described above, when the amount of received information stored in the memory is full of the storage capacity of the memory, When newer information is received, the oldest information stored in the memory is automatically erased in order to secure an area for storing the new information.

Therefore, in a receiving device that receives a plurality of types of information, if there are differences in the providing cycle of various types of information, a lot of information with a short providing cycle is stored in the memory, and information with a long providing cycle is not stored at all. However, even if it is done, it will be stored only slightly, and there will be a problem that the balance of storage of various information will be unbalanced.

On the other hand, as a method of storing various kinds of information in a well-balanced manner, it is conceivable to allocate a memory area for each kind of information in advance. There is a drawback in that it is not possible to deal with the need to do so.

The present invention has been made in view of the above circumstances, and an object of the present invention is to set various information in a well-balanced manner and to freely variably set respective storage capacities of various information as needed. An object of the present invention is to provide an information receiving device capable of performing the above.

[0008]

That is, the present invention provides an information receiving apparatus for receiving information provided periodically.
A storage unit that receives a plurality of types of information, and a memory that stores a plurality of types of information received by the reception unit together with the type information thereof, and stores at least one information type and stores the selected information type in correspondence with each selected information type. If the information type of the information received by the receiving unit is the same as the selected information type by setting the capacity, the capacity of the received information and the information of the information type stored in the memory It is determined whether or not the sum of the above is within the set storage capacity range, and when it is determined that the sum exceeds, the oldest information of the same type as the received information in the memory is erased. The received information is stored in the memory, so that various kinds of information to be stored in the memory can be balanced and the storage capacity of each of the various kinds of information can be variably set as needed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to an information receiver for receiving information such as stock prices provided by using a wireless paging system will be described below with reference to the drawings.

FIG. 1 shows the circuit configuration. In the figure, 11 is an antenna, and the radio wave of the call including the information received by the antenna 11 is sent to the radio unit 12. This wireless unit 12
The decoder unit 13 is driven to perform intermittent reception, amplifies and demodulates a received radio wave, and sends it to the decoder unit 13.

The decoder unit 13 checks in advance whether or not the called number matches with its own identification number (ID code).
Judgment is made by referring to the ID-ROM 14 in which the D code is registered, and if they match, the radio unit 12 continues to receive signals and sends a call detection signal to the CPU 15. And CP
The information type data and the received information are C based on the request of U15.
Send to PU15.

In this case, when the ID code is different for each provided information, a plurality of necessary ID codes are registered in the ID-ROM 14 in advance, and the called number has a plurality of I.
The information for identifying which ID code of the D code, that is, the identification information of the ID code for which the match is detected, becomes the information type data.

When a plurality of information of different information types are provided by one ID code, the information type code for determining the information type added to the information or the function bit of the address code word in the POCSAG signal. Is the information type data.

The CPU 15 controls the operation of the entire other circuit in response to a signal from the decoder section 13 and an input signal from the key input section 16, and is composed of a ROM storing various control programs and a timer. It is connected to the RAM 17 which stores a plurality of received information, and stores the received information and management data in the RAM 17, while outputting a sound emission signal to the speaker 19 via the amplifier 18 and a lighting signal to the LED 21 via the amplifier 20. Each of them is sent to notify that there is a call, and the character pattern corresponding to the received information is read from the character generator (indicated as "CG" in the figure) 22 and stored in the display buffer 23. It is displayed as display data on the configured display unit 24.

As shown in FIG. 2, the RAM 17 has a register section 17a which is a register for holding various data for control operation, a management data storage section 17b which stores various management data for each of a plurality of information types, and received information. The reception information storage unit 17c sequentially stores

The register section 17a is a buffer register for temporarily holding the received information, a main mode register for storing selected states such as a main mode of the receiver, that is, a stock price information display mode, a market price information display mode and a time adjustment mode. M, a display pointer P, and a clock register that holds the clock data while updating them occasionally under the control of the CPU 15.

The management data storage unit 17b has an information type data register, an F1 flag register indicating that the maximum storage number is valid, an F2 flag register indicating that the minimum storage number is valid, for each of a plurality of information types. The maximum storage number data register and the minimum storage number data register are set as one set, and a storage area for the maximum number of sets of information type data is provided.

The reception information storage section 17c has a plurality of storage areas each including an information type data register for storing information type data, a reception data register for storing received data as the content of information, and a reception time register. Have. The information of each set stored in the received information storage unit 17c can be displayed on the display unit 24 by key operation.

Here, the signal is received by the antenna 11 and is transmitted to the radio section 12
The configuration of the selective call signal demodulated in 1. will be described.
For example, the selective call signal of the POCSAG system, which has become an international standard, is composed of a header part for synchronizing bits, which is a preamble, and a data part, which is one or more N consecutive batches.

One batch includes a sync code word and eight subsequent frames, and one frame includes two code words. There are two types of codewords, an address (ID-number) codeword and a message codeword, both of which are composed of 32 bits.

The address codeword is a codeword for a calling number (address), which is an address bit consisting of 19 bits in which the first bit is set to "0", and a function bit of 2 bits and an 11 bit. It is configured with a check bit added. Four kinds of calls called multi-address call can be distinguished by the function bit, and by using this function bit, four different kinds of information can be sent to one ID.

On the other hand, the message codeword is a codeword for message information, and a message bit consisting of 21 bits in which the first bit is set to "1" and 1
It consists of one check bit, and if there is a message, it is transmitted following the address codeword. That is, the provided information such as the stock price is transmitted using this message codeword. Next, the operation of the above embodiment will be described.

FIG. 3 mainly shows the contents of processing when the CPU 15 receives an information, and this processing is started at the time when the call detection signal is inputted from the decoder section 13 to the CPU 15. At the beginning of the processing, first, the information seed data of the information received in step A1 and the received data are fetched and held in the buffer register in the register section 17a of the RAM17.

Next, in step A2, the management data storage unit 17b is referred to by the information type data, and whether or not the maximum storage number is set for the information type data is checked by the flag "1" in the corresponding F1 flag register. It is determined whether or not it is set.

As described above, the information type data has a plurality of ID codes which are different for each provided information in the ID-ROM.
If the ID code is registered in the ID No. 14, the identification information of the ID code detected as a match is directly taken as the information type data, while if only one ID code is registered in the ID-ROM 14, the ID code is registered. The information type code and the function bit of the address code word added in the information data received subsequently are incorporated.

When it is determined in step A2 that the maximum storage number is set and the flag "1" is set in the corresponding F1 flag register, the CPU 15 then temporarily receives the received data in step A3. Information storage unit 17c
Suppose that the number of pieces of information of the information type stored in the reception information storage section 17c exceeds the maximum storage number stored in the management data storage section 17b.

If it is determined that the maximum memory number is exceeded,
Next, in step A4, the oldest reception time data among the information of the same information type data stored in the reception information storage section 17c is selected and erased.

After that, in step A5, the received data held in the buffer register in the register section 17a is newly stored in the received information storage section 17c together with the information type data and the time data in the clock register.

Subsequently, in step A6, the character pattern corresponding to the received data is read from the character generator 22, is displayed on the display unit 24 via the display buffer 23, and the speaker 19 and the LED 21 are notified of the arrival of the incoming call. This is the end of the processing of the CPU 15 for this incoming call.

Further, when it is determined in step A2 that the maximum storage number is not set for the information type data of the received information, or even if it is set, the above step A03 is performed.
If it is determined that the number of pieces of information of the information type does not exceed the maximum storage number even if the received data is stored in the reception information storage section 17c, the process proceeds to step A7, and the RAM 17 is stored regardless of the information type data. It is determined whether or not the information is fully stored in the reception information storage unit 17c.

If not completely stored, the process proceeds to step A5 and the received information is stored in the received information storage section.
It is stored in 17c, but if it is fully stored, R
In order to avoid the overflow of AM17, next, in step A8, the oldest reception time data among the information stored in the reception information storage unit 17c is selected as a candidate of information to be erased.

Then, in step A9, the management data storage unit 17b is referred to from the information type data of the selected information, and whether or not the minimum storage number is set for the information type data is flagged in the corresponding F2 flag register. It is determined whether or not "1" is set.

If the minimum storage number is not set, the information selected from the reception information storage section 17c is erased as it is in step A11, and a storage area is secured in the reception information storage section 17c. Leading to.

If it is determined in step A9 that the minimum storage number is set for the information type data,
Then, if the selected information is erased from the reception information storage unit 17c in step A10, the number of pieces of information of the information type remaining in the reception information storage unit 17c is maintained at the minimum storage number stored in the management data storage unit 17b. Determine if it is possible.

If it can be maintained, step A as it is.
In step 11, the selected information is erased from the reception information storage section 17c, and after the storage area of the reception information storage section 17c is secured, the storage processing of the above step A5 is reached, but if it is determined that the storage processing cannot be maintained, step A12 Then, the next oldest reception time data item is selected from the reception information storage section 17c as a candidate of information to be erased, and the processing from step A9 is repeated again.

As described above, the management data storage unit 17b
The maximum number of memory and the minimum number of memory are set for each information type, and old information is deleted if necessary according to the setting, and the received information is stored, so that the difference in the provision cycle can be dealt with. A well-balanced reception information storage unit for multiple types of information 17
It can be stored in c.

Next, the contents of processing when setting data in the management data storage unit 17b will be described with reference to FIG. This figure shows the processing performed by the CPU 15 by operating a mode key, a "registration" key, a "confirmation" key, a "stop" key, and other numerical keys provided in the key input unit 16.
At the beginning of the processing, first, as shown in step B1, the setting mode is selected by operating the mode key, and then in step B2, the information type to be set is selected.

After that, at least one of the maximum storage number and the minimum storage number is input for the information type selected in step B3, and the operation of the "register" key is awaited in step B4. The processes of steps B3 and B4 are repeatedly executed until the "registration" key is operated, and when the "registration" key is operated, the next step B5 is reached.

In step B5, the number of stored information is set by comparing with the number of information of the corresponding information type stored in the received information storage unit 17c based on the maximum number of input storages. It is determined whether or not the maximum storage number is exceeded.

If it is not over, it is assumed that there is no problem and the setting data input in step B12 is newly registered in the corresponding position of the management data storage unit 17b, and a display indicating that registration has been made is displayed on the display unit 24. This completes the setting process.

If it is determined in step B5 that the number of pieces of information already stored in the reception information storage section 17c exceeds the set maximum storage number, step B6 Then, the speaker 19 and the LED 21 notify the user, and the operation of any one of the "confirmation" key, the "stop" key and the "registration" key is awaited.

That is, it is judged whether or not the "confirm" key is operated in step B7, and "stop" in step B9.
It is continuously determined whether or not the key is operated and whether or not the "register" key is operated at step B10.

When the "confirm" key is operated, the process proceeds from step B7 to step B8 for each operation, and a confirmation process for sequentially displaying received information of the same type as the selected information type is executed, and then step B9. Leading to.

When the "stop" key is operated, step B
The process advances from step 9 to step B13 to cancel and invalidate the data of the maximum storage number and the minimum storage number that have been set, and this processing is once ended.

When it is determined in step B10 that the "registration" key has been operated, the process proceeds to step B11, and the number of stored information of the same type as the selected information type stored in the received information storage section 17c is determined. The old information is deleted from the reception information storage unit 17c based on the reception time data so that it becomes the same as the newly set maximum storage number. After that, the setting data input in the above step B12 is newly registered in the corresponding position of the management data storage unit 17b, the corresponding flag registers F1 and F2 are set, and the display unit 24 displays a message indicating the registration. This completes the setting process.

In the incoming call process shown in FIG. 3, if it is determined in step A7 that the information is fully stored in the reception information storage section 17c of the RAM 17, the information is erased in steps A9 to A12. Although the information of the information type that cannot maintain the minimum storage number is not erased, instead of or in addition to this configuration, the information of the information type for which the maximum storage number is set may not be erased. in this case,
Since the number of pieces of information for which the maximum number of storages is set does not change, the number of pieces of information required at all times can be secured.
