BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display data scanning method of a display device that accesses and displays stored display data by switching control, and in particular, converts a scanning display cycle of a message received and stored in a pager receiver according to an operation state of a switch. It is about how to. In general, a communication device and a display device with many echoed messages are accessed and displayed by a memorized control signal. Current display type receivers, for example, pager receivers, decode the received code and store the received message. Typically, tens or hundreds of digits of messages are stored and displayed.

1 is a block diagram of a pager receiver as a display type receiver as described above, and its configuration is as follows. An antenna 1 for receiving an RF modulated signal, an RF receiver 2 for demodulating the RF modulated signal from the antenna 1, a demodulated signal of the RF receiver 2, and a secondary signal A waveform shaping unit 3 for shaping a waveform, an EEP ROM 5 storing its own data for discriminating data of a corresponding pager receiver, a pager receiver, and controlling for power saving at predetermined periods. Outputs the signal BSS and simultaneously inputs the reception data of the waveform shaping unit 3, compares the data with the data of the EEP ROM 5, and determines whether there is qualified data, and displays the stored message and the receiver by the lead key. The microcomputer 4 for controlling the state of the alarm, an alarm driver 6 for generating an alarm signal under the control of the microcomputer 4, and a speaker for generating an alert tone in the alarm driver 6 ( 7) messages and status data under the control of the microcomputer 4; LCD (8) for displaying the key, the key input unit (9) for generating a silent signal for preventing the display of the stored message and the generation of an alarm sound composed of a lead key and a silent key (Silent Key), and the microcomputer (4) It consists of a state driver 10 for displaying the state of the pager receiver under the control of.

2 is a flow chart of a method of displaying a message stored by input of a lead key as a conventional display data display flow diagram. First, before describing the conventional display data display method with reference to FIGS. 1 and 2, an operation process of a pager receiver will be described. A pager-reveiver is a small radio receiver for calling people whose location is unclear or moving through a paging system, a land base station. The pager receiver typically uses a POCSAG code, and a paging system assigns a cap-code (hereinafter referred to as a CAP-Code) corresponding to each pager address to call the pager receiver. In addition, the paging system makes a binary change and propagates the air with an 18-bit address and 3 bits of frame data. The pager receiver operates on this signal. The CAP-code mentioned above is an I.D code between the paging system for calling the pager receiver and the pager receiver, and has a pager calling number to call the pager receiver on the telephone. That is, a pager call number is assigned to each pager receiver like a normal telephone, and a CAP-code is assigned one-to-one correspondingly. Therefore, the general subscriber inputs a pager call number on the telephone to call the pager receiver, and when this data is input to the paging system, the paging system converts the input pager call number to the corresponding CAP-code and in a predetermined manner. After encoding, it is modulated and propagated to the air. At this time, the manager receiver receives the radio signal, compares the CAP-code embedded in the pager with the data in the received signal, and displays a message on the LCD or drives an alarm when its CAP-code is detected. Should be.

FIG. 1 is a block diagram illustrating a pager receiver for carrying out the present invention. When the paging system propagates a call signal according to the above scheme, the antenna 1 receives it. The RF receiver 2 receiving the RF signal modulated by FSK and transmitted through the antenna 1 amplifies and demodulates the received data in a modulated state. It is assumed here that the data or message is a message in the form of POCSAG code. The waveform shaping section 3, which receives the demodulated signal of the RF receiver 2, filters and amplifies the demodulated data, and shapes it to a secondary level to apply it to the microcomputer 4. The microcomputer 4 stores an address in the EEP ROM 5 in an internal memory RAM of the microcomputer 4 when the initial power is turned on, and among the POCSAG codes received through the waveform shaping unit 3. The corresponding address bit (18 bits) is also stored in the memory, and the two addresses are compared to determine whether data is eligible. The microcomputer 4 uses a one chip processor. In the EEP ROM 5, two addresses (dual addresses), each consisting of 18 bits of address bits and 3 bits of frame data indicating a self-address of a pager receiver, are stored. At this time, the microcomputer 4 selects 3 bits of magnetic frame data from the data received in 8 frames per batch by using this frame bit, and selects 18 bits of address data bit and EEP from the received data contents of the magnetic frame. The presence or absence of the eligible data is determined by comparing with the self-specific 18 bit address data stored in (5). When the received data is found to be eligible data as described above, the microcomputer 4 receives the message data, stores it in the EEP ROM 5, displays it on the LCD 8, and simultaneously drives the alarm driver 6 to alert the alarm signal. The speaker 7 generates an alarm sound by this signal. The pager receiver as described above may generate first and second key data through the key input unit 9, generate the first key data through the lead key 91, and use the silent key 92. Generates second key data. The silent key 92 generates a key command for preventing the driving of an alarm sound upon receiving a message. In this case, the received message is stored in the internal memory of the microcomputer 4 and at the same time through the LCD 8. Is displayed for a while, and calling information is displayed after the display. When the silent key 92 is on, it is in silent mode, and when it is off, it is operated in normal mode. Also, the lead key 91 is used to stop the alarm sound generated when a message is received, or to access the stored message on the EEP ROM 5 under the control of the microcomputer 4 and to display the LCD 8 on the LCD. do. In addition, the status display unit 10 indicates various states of the pager receiver under the control of the microcomputer 4, and the lamp 102 is operated while displaying a message on the LCD 8, even when there are many readings of the message, such as at night. Clearly displays the message and stays off during the call cycle. The LED 103 is driven when a message is received to visually indicate an alarm state. The LED 103 is driven in both a normal mode and a silent mode. In addition, when the message is received in the silent mode, the motor 104 vibrates the pager receiver so that the user can recognize it. It starts from whether the lead key 91 is input as shown in the conventional second diagram for accessing and displaying the received message stored in the EEP ROM 5 in the pager receiver operated as described above. When the lead key 91 of FIG. 1 is pressed and the lead key is broken in step 2a, the microcomputer 4 searches whether the tone is turned on in step 2b. At this time, the tone means that the microcomputer 4 determines whether the alarm signal is output to the alarm driver 6 or the state driver 10, and when the tone signal is turned on, the tone signal is returned by the lead key 91. The tone is determined to be set, and the tone is reset in step 2c. If there is no tone signal while the lead key is input, the microcomputer 4 determines whether there is a stored message in the EEP ROM 5 by determining that the stored message is accessed. If there is no message stored as a result of the search in step 2d, the process returns to the main routine, and if there is a stored message, the received message stored in the EEP ROM 5 is accessed and displayed on the LCD 8 in step 2e. do.

In the conventional method operating as shown in FIG. 2, the lead signal by the lead key 91 is repeated once, and the access message is increased one by one, stored in the EEP ROM 5 at each input. However, the conventional method operating as shown in FIG. 2 is very inconvenient to check from the first message to the last message when there are many memorized received messages. For example, if one message is more than 12 bits, the message confirmation time is long, and the user is inconvenienced because the lead key 91 has to be repeatedly pressed once to confirm the storage message of the beginning and the end.

Accordingly, an object of the present invention is to provide a method for automatically scanning and displaying a memorized message under a predetermined control in a display type receiver for storing and displaying received message data in a memory.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for automatically scanning and displaying an access time interval of a message according to a switch operation when a memory device displays a message having a large number of memorized message data. have.

It is still another object of the present invention to provide a display type receiver operating with a predetermined operation mode, wherein when a data lead signal of a stored message is continuously input for a predetermined time, the data access time interval of the stored message is automatically adjusted according to the number of stored messages. It provides a method for displaying by.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 is a flowchart of a method of converting a data scanning time of a stored message according to the present invention.

4 is a flowchart of another example of a data scanning conversion method of a stored message according to the present invention.

The operation of FIGS. 3 and 4 according to the present invention will be described in detail with reference to the above-described block diagram of FIG. When the call signal is received by the pager receiver as shown in FIG. 1, the microcomputer 4 analyzes the received data and stores the necessary data in the EEP ROM 5, which is described in the present invention. Explain only.

의 타임으로 메세지 데이터를 스캔닝 표시하는 것은 첫째 숫자(Numeric Type)의 무선수신기에는 억세스가 용이함으로 고속 스캔닝 표시하기 위함이다. 둘째 분자(Alpha-Numeric Type)의 무선수신기에서는 데이터의 내용이 많음으로 저속디스플레이하기 위함이다. 따라서 제3도의 제어방법으로는 보통 상태속도 Y타임, 고속상태 Yn, 저속상태

3가지의 모드로 페이저 수신기의 메세지 데이터 디스플레이 속도를 조절할 수 있다.When the microcomputer 4 performing the normal mode operation performs the kisscan operation, the microcomputer 4 performs a third operation process as described above in the processes of FIGS. 2A, 2A, 2B, 2C, and 2D. 3A, 3B, 3C, and 3D are performed to search whether there is any message data stored in the EEP ROM 5. Of course, if the result of the corresponding search is not valid during the search process of FIGS. If the message data is stored in the EEP ROM 5 in the above 3d process, the microcomputer 4 determines whether the ON state of the lead key 91 is maintained for more than ＂X＂ (XX is a natural number rather than ＂0＂) seconds. Search in Figure 3e 3e. If the press of the lead key 91 has not elapsed 占 X seconds since the process shown in FIG. 3e, the microcomputer 4 searches whether the lead key 91 is turned off in process 3i. At this time, if the lead key 91 is off, the microcomputer 4 accesses the message data at the initial address in the EEP ROM 5 and outputs the message to the LCD 8 to display the message. If it is determined in step 3e that the holding state of the lead key 91 is maintained for more than X seconds, or if the lead key is not turned off in step 3i, the microcomputer 4 displays the current state in step 3f. Search whether the operation mode is normal mode. In operation 3f, it is determined whether the normal mode is input according to whether the second key data is input according to the switching of the silent key 92. If the silent key 92 is turned off, the microcomputer 4 currently operates. If it is in normal mode and is on, it is determined to be in silent mode. In this case, the normal mode refers to an operation mode that outputs an alarm sound, and the silent mode refers to an operation mode in which an alarm sound is reset and cut off. If it is determined that the current mode is the normal mode in step 3f, the microcomputer 4 has Y sec time interval (Y Y is a non-zero natural number) and the initial state of the EEP ROM 5 is determined. The message data of the last address containing the message data from the address is accessed and displayed on the LCD 8. Therefore, if the lead key 91 is turned on for more than X seconds, and the current mode is the normal mode, the microcomputer 4 sequentially accesses the message data stored in the EEP ROM 5 at intervals of Y seconds time interval intervals, and displays the LCD. Display through (8). If the current mode is not the normal mode in the above-described 3f process, the microcomputer 4 has time intervals of y and x seconds and sequentially accesses the message data in the EEP ROM 5 and displays it on the LCD 8. (Y Is a non-zero natural number, x is n or 1 / n and n is a non-zero natural number.) Therefore, if the lead key 91 is on for more than ＂X＂ seconds and the current mode is the silent mode, the microcomputer 4 By sequentially accessing the message data stored in the EEP ROM 5 with y, x second time intervals and outputting them to the LCD 8, the display is slower or faster than in normal mode. As described above, the control according to the flowchart of FIG. 3 outputs and displays the message data stored in the EEP ROM 5 with a predetermined time interval. At this time Yn or in the above 3g process

Scanning and displaying the message data at the time of is to display high-speed scanning because the first number of wireless receivers are easily accessible. The second molecule (Alpha-Numeric Type) wireless receiver is to display a low speed because of the large amount of data. Therefore, in the control method of FIG. 3, normal state speed Y time, high speed state Yn, low speed state

Three modes are available to adjust the message data display speed of the pager receiver.

4 is a flow chart of another embodiment of the present invention. The processes 4a, 4b, 4c, 4d and 4e of FIG. 4 are the same as those of 3a, 3b, 3c, 3d and 3e of FIG. Therefore, the description of FIG. 4 will be described after the process of FIG. 4F. In the process of FIG. 4F, as described with reference to FIG. 3F, the microcomputer 4 searches whether the normal mode is used as the second key data corresponding to the on / off state of the silent key 92. FIG. At this time, if the mode is the normal mode, the microcomputer 4 sets the omnidirectional scanning flag in FIG. 4G, and if the silent mode, the microcomputer 4 sets the backward scanning flag in FIG. 4H. Therefore, according to the mode by the operation of the silent key 92, the microcomputer 4 decides whether to carry out the scanning of the data of the EEP ROM 5 in the forward direction or the backward direction. In step 4g or 4h, the microcomputer 4 that sets a flag indicating the scan direction searches for the number of message data stored in the EEP ROM 5 in step 4i and sets a scan period according to the result. If the number of message data M is larger than " 0 " and less than " 10 ", i.e., there are 10 or less stored message data, the LCD 8 can be scanned by sequentially scanning the message data stored in the EEP ROM 5 in units of 2 seconds. Will be displayed. If the number of messages is less than # 40, the microcomputer 4 scans and displays the message data in the EEP ROM 5 at intervals of 1 and 5 seconds. If the number of messages is 40 or more, the microcomputer 4 accesses and displays the message data at high speed with the scanning period of 1 second. The microcomputer 4 performing the process 4i performs processes 4j and 4k as described above in FIGS. 3i and 3j. Therefore, when the control shown in FIG. 4 is executed, the scan period is determined according to the number of message data stored in the EEP ROM 5, and the result is sequentially increased and displayed.

As described above, the present invention can change the automatic scan display period according to a switch operation when checking a received message in a display type receiver such as a pager receiver, so as to facilitate the user's convenience when checking and checking a large amount of messages. can do.
