Abstract

The power saving method of wireless pager uses the switch control supplied by a battery power source to restrain the power consumption of the battery. The method includes a step to recover the battery voltage by extending the power-off state of battery's power supply when the battery voltage is dropped to a pre-determined voltage. A wireless paging receiver, which comprises a receiving loop and a controlling loop, uses the pre-determined cycle in implementing the switch controller of the receiving loop battery's power supply to control the power consumption of the battery's power voltage. The controlling loop is equipped with a reference detection loop that compares the voltage of the battery's power voltage with a pre-determined reference voltage, and a counter, which is controlled by the output of the reference detection loop. When the battery voltage is higher than the pre-determined reference voltage, it will calculate a normal switch-off state period to restrict the power assumption. When the battery voltage is lower than the pre-determined reference voltage, it will calculate an extending switch-off state period longer than a normal switch-off state period.

When the power source is open or the area is searched, the receiver scans, and according to the scan, the field continuously receives the area that is currently receivable, and thus determines the reception frequency of the current location. In this service, the number of frequencies that can be registered in the scan directory can be as high as 20. Also, in today's receivers that support multiple area services, the scanning system is used to determine the strength of a given signal field so that fans can scan a large number of scan callers. Has become mainstream. Compared with the conventional signal search in the pattern match system, the measurement of the signal field strength can be performed very quickly. For example, for a domestic (Japanese) FLEX-TD system, the search time for each frequency of the aforementioned system can be reduced to about 300 milliseconds, and the system described later takes about 2 seconds. On the other hand, 'recently' beer makers have made great progress in miniaturization and weight reduction ', so' callers' using small size and low weight air batteries have also increased. V. Description of the invention (2) However, when the air battery has a power-consuming load, its voltage gradually decreases, and when it is removed, the circuit that uses the air battery's power consumption needs a very large circuit will cause the battery voltage to drop. The on-state operation will continue to be performed in a normal receiving or scanning operation of the display-operated scanning pager due to the sudden replacement of the battery. Therefore, the "objective method of the present invention" is capable of suppressing battery power collection operation. Another object of the present invention is a method which can prevent erroneous changes. A further object of the present invention is to suppress the operation of the battery power supply. A further object of the present invention is to prevent erroneous battery replacement. According to the present invention, a power saving method of suppressing a pager by (ON / OFF control) includes:

The signal 丨 is a power-saving signal, which controls the power on / off of the receiving section. The signal 丨 represents the on state of the receiving / receiving segment 102 at the high level on time and the low state represents the off state of the receiving segment 〇2. The on-state time of the receiving section 102 is set to 2 seconds and the off-state time is set to 40 milliseconds. The signal j represents the change of the battery voltage with time. The dashed line 讣 represents the threshold level of the battery voltage (LVA discrimination level), where th is set to ^ volts. The signal P is the output of the level discrimination device 109. Its low level indicates that the battery voltage is higher than the LVA discrimination level voltage, and the high level indicates that the battery voltage is lower than the LVA discrimination level voltage. The signal k is an output signal that releases the signal p at the falling edge of the power-saving signal i. The signal / is a count end pulse for receiving the off state of segment 102 and is not LVA, and the signal m is a count end pulse for receiving the off state of segment 102 and L. The off-state time of the receiving segment 102 is set to 40 milliseconds when it is not LV A, and the off-state time of the receiving segment 102 is set to 10 seconds when it is L VA. The signal 0 is the output of the signal selecting device 113 for selecting the counting end pulse wave of the first and second counting devices 1 and 112. The situation shown in FIG. 3 is that before time 130, the battery voltage is reduced due to the use of the vibration function, and scanning is started from t30. As the scan is started, the battery voltage is further reduced, and then it is lowered to the threshold level 'at time 13 3, so that the signal p becomes a high level. Then, the receiving section 102 is switched to the off state at time t35, and the level discrimination result is latched. 丨 α 〇 Page 11 423234 5. Description of the invention The high level of the signal P is released and the signal k becomes the high level output. Since the signal k is still at a low level before time t35, at time t3, t32, and t3 ^, the first counting device 丨 i calculates the 8-level L time of the receiving section ι〇2, that is, 40 耄 seconds, and count The end signal z becomes the signal 0, and the completion of the counting is notified to the central processing unit 04. When the signal k becomes high, 1 the first counting device iu is prohibited from operating and the second counting device 112 is allowed to operate. Then, when the power-saving signal i becomes a low level, a counting operation is started to ensure that the off-state time of the receiving section 102 is 10 seconds.

當第二計數裝置112在時間t34 + 10後產生一計數结束 脈波時，訊號選擇裝置113由訊號k選擇訊號m並作為=號〇 輸出’因而將計數的完成通知中央處理機1〇4。此後，中 央處理機104開始接收段1〇2的開狀態的處理，使訊號i成 為1¾位準。 在時間t35到時間t35 + 10之間接收段1〇2為關狀態的期 間’ 1 0秒，負載減少因而電力消耗亦減少，因此代表電池 電壓供應的電壓位準的訊號j回復至超過臨限位準。因 此’掃描操作可在此後繼續實施。並且，LVA發生判別震 置1 14在此期間從未偵測得連續三次的LVA位準，因而LVa 發生判別的結果能夠防止因為訊號η的高位準而產生的錯 誤警報。 圖4所示為一習知技術的時間圖。在習知技術中，同 樣提供有第—計數裝置和中央處理機且中央處理機由輸出 類似於本實施例的省電訊號I以實施接收段電源供應的開 /關控制。但是，由於沒有提供相當於第二計數裝置等的When the second counting device 112 generates a counting end pulse after the time t34 + 10, the signal selecting device 113 selects the signal m from the signal k and outputs it as the number = ', thus notifying the central processing unit 104 of the completion of the counting. After that, the central processing unit 104 starts the processing of receiving the on state of the segment 102, so that the signal i becomes 1¾ level. During the period between time t35 and time t35 + 10, when the receiving section 10 is OFF, 10 seconds, the load is reduced and the power consumption is reduced. Therefore, the signal j representing the voltage level of the battery voltage supply is returned to exceed the threshold. Level. Therefore, the 'scanning operation can be continued thereafter. In addition, the LVA discriminant tremor is set to 1.14 During this period, the LVA level has not been detected for three consecutive times. Therefore, the LVA discriminant result can prevent false alarms due to the high level of the signal η. FIG. 4 shows a timing chart of a conventional technique. In the conventional technology, a first counting device and a central processing unit are also provided, and the central processing unit outputs a power saving signal I similar to this embodiment to implement on / off control of the power supply of the receiving section.

'Causes the on state of the power saving signal i to be continuously generated. Therefore, the signal output from the central processing unit after the root discriminating device has measured the LVA level three times in succession gives a power-saving signal in the off state. In the conventional technology, as shown in FIG. 3, In some cases, before 140, the battery voltage was reduced due to the use of the vibration function, and the scan was started at t40, and the battery voltage would drop to the pro & level at time U1. However, since scanning has not been stopped, at the points A, B, and C where the receiving section transitions from the on state to the off state, the LVA level is detected three consecutive times. Therefore, the power supply voltage is not restored, and the discriminating device stops receiving operation at time t43 and generates a low-voltage alarm. FIG. 5 is a block diagram of another suitable embodiment of the present invention. Compared with the embodiment of FIG. 1, this embodiment is provided with only one counting device. The level determination result k is input to the central processing unit and the reception & off-state time selection in LVA and non-LVA is controlled by software. . 5Π is a counting device, in which the part relative to the comparator of FIG. 2 is constituted by a register and its comparison value can be set by the central processing unit 504. Because of this, different values can be counted. ^ According to the level discrimination result, the latch device 5 1 0 outputs when the receiving section changes from the on state to the off state. The central processing unit 504 sets the count value of the counting device 511 to determine the off state time of the receiving section. When the count reaches the set value of the central processing unit 504, the 'counting device 511 outputs a counting end signal due to the signal 3' to the central processing unit 504, and notifies the reception section of the off-state time. That is, the counting value of the counting device is set by the central processing unit 504, for example, when the non-l v a

Description of the invention (11) is 40 milliseconds and LV A is 10 seconds. FIG. 6 shows an operation flowchart of the central processing unit 504 of this embodiment. After the off state (RXOFF) of the receiving section and the power-saving signal i is changed from the high level to the low level (step S1), the round-robin signal k as the logic state of the latch device 510 is read as a result of the level discrimination (step S2) ) To determine whether the battery voltage is at the LVA level (step S3). When the signal k is at a low level, a count value of 40 milliseconds is set as the off-state time of the reception section to the counting device 510 (step S4). When the signal 1 ^ is at a high level, a count value of 10 seconds is set (step S5). After the count value is set, the count operation is allowed (step S6). The completion of the counting can be recognized by the signal of the counting device 511 (step S7), and then the off-state time of the receiving section is ended, and the processing of the on-state of the receiving section is performed. In this embodiment, since the central processing unit sets the counting value, the two counting devices can be combined into one device. In addition, the 'single counting device can be used not only to calculate the off-state period of the receiving section but also to calculate the on-state period of the receiving section. Therefore, 'the central processing unit can be used as a general-purpose counter when the power-saving control is implemented', and the present invention can be implemented without increasing the loop size. Read and 'When the setting data of the central processing unit can be read from the erasable and lightly readable memory and the erasable and programmable in the receiver configuration only = when the memory can be rewritten from outside' the count value can be Set from the outside. ° Advantages of the present invention In the wireless call receiver of the present invention, when the battery power

Therefore, the battery power in the loop can prevent low load caused by operation and errors, especially in wireless pagers. Recognized as battery life and delayed by time, so for example, although the reliability of the signal operation is described in the present description, the frequency scan system of electrical power consumption is added to the alarm detection level with well-known technology, so the cost is temporarily reduced. The invention source is temporarily used for the temporary voltage alarm, but it can be temporarily stopped, and the scanning result can prevent the field test, and the battery report at that time. Multi-zone time delay can prevent mistakes. Detect temporary errors. Battery is delayed to wait for voltage drop. Use the battery in the low-voltage operation when the battery is mistakenly made. The supply of sources expressly intended to make changes and modifications to the complete and clearly disclosed scope of the patent application has been temporarily postponed. When the voltage of the battery is also lowered, it will be used for the frequency of misreceiving when the battery voltage is low. The scanning and scanning operation is caused by the voltage drop when the voltage of the low voltage alarm is reduced. Therefore, it can often be exposed to borrow specific Subject to such restrictions, there are implementation methods. From time to time, the battery can be restored until it receives a reply.
