Description
    BACKGROUND OF THE INVENTION
  • [0001]
    1. Field of the Invention
  • [0002]
    The present invention relates to a wireless apparatus, and more particularly to a wireless apparatus with a function to convert the data format of a received data.
  • [0003]
    2. Description of the Related Art
  • [0004]
    A wireless apparatus receives a desired data and displays the received data on a display section. At this time, when the received data is merely displayed without application of any processing, a sequence of characters or numerals of the received data is merely displayed, as shown in FIG. 1. Accordingly, it is difficult to recognize, for example, the temporal change of the desired data. Especially, in a portable information receiver such as a pager, because a memory capacity is limited, a system is generally adopted in which only the latest information is stored. For this reason, it is not possible to display the data previously received once again. Thus, in a portable information receiver, it is difficult to recognize the temporal change of the data further than in the above-mentioned wireless apparatus.
  • [0005]
    An information display apparatus is disclosed in Japanese Laid Open Patent Disclosure (JP-A-Heisei 8-55153), in which the temporal change of a data can be easily recognized. In this information display apparatus, received stock market data are classified and rearranged for every category of business and displayed in a graph form, to allow stock market data to be visually recognized.
  • [0006]
    [0006]FIG. 2 is a block diagram illustrating the structure of the information display apparatus mentioned above. Referring to FIG. 2, the information display apparatus is composed of a CPU 111, a receiving unit 112, a data storage area 113, an input unit 114, a main memory having a program area and a work area, an external storage unit 116, and a display unit. The receiving unit 112 receives a stock market data which is sent through a communication channel, and the CPU 111 stores the received stock market data in the data storage unit 113. A company name is designated through the input unit 114. The CPU 111 classifies the stock market data which has been stored in the data storage unit 113 in accordance with the designated company name and rearranges them in order. Then, the CPU 111 displays the stock market data for the designated company name on the display unit 117. Also, the CPU 111 displays the quantities of sold and bought stocks for the designated company name with different colors in the form of graph on the display unit 117.
  • [0007]
    However, in the above information display apparatus, since the received data is used for a data base, the received data is stored just as it is received without application of any processing. In addition, the data converted into the form of graph is also stored. For this reason, there is a problem in that the quantity of data to be stored increases. In accordance with, the sufficiently large memory capacity must be provided previously in the information display apparatus. This is a fatal problem, especially, in the portable information receiver such as a pager in which the memory capacity to be mounted is limited.

  • DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • [0027]
    Next, the wireless apparatus of the present invention will be described below in detail with reference to the attached drawings.
  • [0028]
    [0028]FIG. 3 is a block diagram illustrating the structure of the wireless apparatus according to an embodiment of the present invention. Referring to FIG. 3, the wireless apparatus is composed of an antenna 1, a radio section 2, a decoder 3, a CPU 4, an identifier (ID) storage section, a main memory section 6, a data converting section 7, a sub-memory section 8, an informing section 9 and a display section 10. The antenna 1 receives a wireless signal, and the radio section 2 amplifies and demodulates the received wireless signal, and the decoder 3 processes the demodulated signal. The CPU 4 controls a receiving operation by the radio section 2 and the decoder 3. Also, the CPU controls the whole of the wireless apparatus. The ID storage section 5 stores identification numbers of the wireless apparatus. The data converting section 7 stores a plurality of data conversion formats. Each of designated ones of the identification numbers is related one of the plurality of data conversion formats. Also, the data converting section executes a data converting operation based on a set data conversion format under the control of the CPU 4. The main memory section 6 stores received message information, and the sub-memory section 8 stores a data which is subjected to the data conversion. The informing section 9 informs the reception of any data to a user under the control of the CPU 4, and the display section 10 displays the received message information and the data which is subjected to the data conversion, under the control of the CPU 4.
  • [0029]
    Next, the operation of the wireless apparatus according to the embodiment of the present invention will be described below. The wireless apparatus previously stores identification numbers for itself in the ID storage section 5. A normal message reception mode or an information reception mode can be set for each of the identification numbers. A data indicative of whether the normal message reception mode or the information reception mode is set is stored in the ID storage section 5 together with the identification number. The user of the wireless apparatus can previously set the data conversion format in the data converting section 7 in the case where a data received in the information reception mode should be displayed on the display section 10.
  • [0030]
    A wireless signal is received by the antenna 1, is amplified and demodulated by the radio section 2, and is supplied to the decoder 3. The decoder 3 extracts a call number from the demodulated signal and a data subsequent to the call number. Since the identification numbers have been already stored in the ID storage section 5, the decoder 3 refers to the identification numbers of the wireless apparatus through the CPU 4 to compare the call number of the demodulated signal with the referred identification numbers. If the call number of the demodulated signal is coincident with one of the referred identification numbers as the result of the comparison, the decoder 3 determines whether or not the normal message reception mode or the information reception mode is set for the call number. Then, the decoder 3 supplies a determination signal indicative of the normal message reception mode or the information reception mode set for the call number to the CPU 4. Also, the decoder 3 supplies a received data of a signal of the demodulated signal subsequent to the call number to the CPU 4.
  • [0031]
    If the determination signal indicates the normal message reception mode, the CPU 4 displays a message of the received data on the display section 10. Also, the CPU 4 outputs a reception informing signal to the decoder 3 such that the decoder 3 drives the informing section 9 to inform the message reception to the user. Further, the CPU 4 stores the received message in the main memory section 6. The above operation is the reception processing operation.
  • [0032]
    On the other hand, if the determination signal indicates the information reception mode, the CPU determines whether or not the data conversion format has been previously set in the data conversion section 7. If the data conversion format has been set, the CPU 4 controls the data converting section 7 to convert the received data based on the set data conversion format to produce a new data. In this case, when an old data which has been already subjected to the data format conversion is stored in the sub-memory section 8, the data converting section 7 reads a necessary portion of the old data from the sub-memory section 8. Then, the data converting section 7 integrates the new data and the read old data portion. The CPU 4 displays the integrated data on the display section 10 as a conversion data. Also, the conversion data is stored in the sub-memory section 8. When any data conversion format is not set in the data converting section 7, the above-mentioned reception processing is performed as in the normal message reception mode.
  • [0033]
    Next, the operations of CPU 4 and data conversion section 7 will be described in detail with reference to FIG. 4.
  • [0034]
    First, to the CPU 4 is supplied the determination signal indicative of the message reception mode or the information reception mode for the call number contained in the received wireless signal and the data subsequent to the call number (Step S1). The CPU 4 determines whether or not a normal message signal or an information signal is received, based on the determination signal (Step S2). If the determination signal indicates the normal message reception mode, the CPU 4 executes the reception processing operation such as the reception informing operation and the message displaying operation (Step S12). On the other hand, if the determination signal indicates the information reception mode, the CPU 4 determines whether or not the data conversion format for the call number is previously set in the data converting section 7 (Step S3). If not set, the CPU executes the above-mentioned reception processing operation (Step S12).
  • [0035]
    If the data conversion format is set, the data converting section 7 searches the data conversion format for the call number in the information reception mode (Step S4). Then, the data converting section 7 receives the received data as a new data from the CPU 4 (Step S5). The new data is converted based on the searched data conversion format (Step S6).
  • [0036]
    Subsequently, the data converting section 7 searches the sub-memory section 8 for an old data for the call number. The old data is already received and converted into the data conversion format (Step S7). The searched old data is integrated with the new data to produce an integration data (Step S8). The integration data is stored in the sub-memory section 8 (Step S9). Further, the CPU 4 receives the integration data from the data converting section 7 and supplies as a display data to the display section 10 (Step S10). As a result, the integration data is displayed on the display section 10. At the same time, the CPU 4 controls the decoder 3 to drive the informing section 9 for the information of the reception (Step S11).
  • [0037]
    When it is determined in the step S7 that there is no old data which is stored in the sub-memory section 8, the above-mentioned operation may be executed to only the received new data. Instead, the operation in the step S12 may be executed.
  • [0038]
    [0038]FIG. 5 shows a flow chart for explanation of the data conversion format setting operation in the wireless apparatus according to the embodiment of the present invention.
  • [0039]
    Referring to FIG. 5, when the wireless apparatus is in a normal wait state (step S21), the user selects a data conversion format setting mode (Step S22). The CPU 4 searches the identification numbers of the wireless apparatus which are previously registered on the ID storage section 5 (Step S23) to determine whether or not information reception mode is set to each of the searched identification numbers (Step S24). If the information reception mode is not set, the control returns to the wait state again.
  • [0040]
    When there is the identification numbers for which the information reception mode is set, the user selects one of the identification numbers for which the information reception mode is set (Step S25). The CPU 4 determines whether a data conversion format is already set for the selected identification number (Step S26). When the data conversion format is not yet set, the CPU 4 registers the selected identification number as the identification number for the information reception mode (Step S27). Further, the CPU 4 selects one of the data conversion formats previously stored in the data converting section 7 for the registered identification number in response to an instruction from the user (Step S29).
  • [0041]
    On the other hand, when the data conversion format is already set, the user determines whether or not the set data conversion format should be reset (Step S28). When the set data conversion format should not be reset, the control returns to the wait state.
  • [0042]
    When the set data conversion format should be reset, the data conversion format is selected for the selected identification number and then the control advances to the conversion setting (Step S29). The data conversion format selected in the step S29 is registered on the data converting section 7 (Step S30). Thus, a data conversion format setting mode is ended (Step S31).
  • [0043]
    When a plurality of identification numbers are registered for the information reception mode, the control from the step S25 to the step S30 is repeated.
  • [0044]
    [0044]FIGS. 6A and 6B show display examples in the wireless apparatus according to the present invention. FIG. 6A is a display example in which only the integration data of “AAA” is extracted from the sub-memory section 8 and is displayed on the display section 10. FIG. 6B is a display example in which all the integration data are displayed. These display examples allows the user to easily recognize the temporal change of the received data.
  • [0045]
    It should be noted that the wireless apparatus of the present invention may be provided with the transmitting function in addition to the receiving function as mentioned above.
  • [0046]
    As described above, according to the wireless apparatus of the present invention, the received data is converted to have a data conversion format and is stored in the memory section. Because it is not necessary that the received data is stored just as it is received, the data quantity is possible to be reduced. As a result, the increase of the memory capacity can be suppressed as less as possible.
  • [0047]
    Also, because the setting of a plurality of data conversion formats is possible, one wireless apparatus can be applied to various types of processing.
  • [0048]
    Further, a newly received data is converted in accordance with the selected data conversion format and is integrated with an old data which has been already converted to produce an integration data. Then, the integration data is stored in the memory section. Thus, the data quantity can be further reduced.
  • [0049]
    In addition, because the data converting section can convert the integration data into the graph data format, the temporal change of the data can be easily recognized.
  • [0050]
    According to the present invention, even if the wireless apparatus is a portable type wireless apparatus in which the memory capacity is limited, the increase of the memory capacity can be sufficiently suppressed as described above.
