Description

Radio Selective calling receiver

The present invention relates to possess the selective call receiver of low power consumption function.

Selective call receiver in the past is used to promote the output of the booster circuit of cell voltage with 1 or 2 voltage detecting circuit monitoring battery voltage or supervision.Selective call receiver with 1 voltage detecting circuit supervision, described among the Japanese Patent Application Publication JP-A-4-342319 the 0002nd section, be to detect the low-voltage of certain regulation and produce the low-voltage alarm by control section by voltage detecting circuit, but, when after this continuing to use the selective call receiver not changing battery, cell voltage will further reduce, and battery is used till the receiver akinesia.

In addition, monitor the selective call receiver with 2 voltage detecting circuits, as described among the Japanese Patent Application Publication JP-A-3-201830 the 0003rd section, 1 voltage detecting circuit is used to produce the low-voltage alarm same with the former, in addition 1 voltage detecting circuit is used to further reduce and when detecting the low-voltage of low value more at cell voltage, stop the action of receiver etc. and make receiver be in the low power consumption state, by receiver being changed to the low power consumption state preventing the rapid decline of cell voltage thereafter, thus the unlikely battery leakage that causes.

Yet in above-mentioned selective call receiver in the past, during with 1 voltage detecting circuit monitor voltage, battery is still continued to use up to the receiver akinesia after the alarm of generation low-voltage.Therefore, might misoperation take place when being about to akinesia, perhaps when having used low-quality battery battery leakage may take place.

During with 2 voltage detecting circuit monitor voltage,, then dispersed just clearly to the time that becomes the low power consumption state from producing the low-voltage alarm because each voltage detecting circuit detects the separation property of voltage.Therefore, if keep almost consistently, then just require to have the higher detection voltage accuracy for each voltage detecting circuit to this time, its result rises cost.In addition, use 2 voltage detecting circuits itself just to improve cost.

For this reason, the object of the present invention is to provide such radio Selective calling receiver, this receiver can monitor produce after the low-voltage alarm or detect low-voltage after time, prevent battery leakage by after a period of time, making it to be in the low power consumption state, and, can reduce cost by using 1 voltage detecting circuit.

For achieving the above object, receiver of the present invention has voltage detecting circuit, timing circuit and control circuit, and voltage detecting circuit is used for monitoring battery voltage or monitors the output voltage of the booster circuit that promotes cell voltage, and detects the low-voltage of regulation; Timing circuit is used for carrying out timing in the moment that detects the low-voltage of regulation from above-mentioned voltage detecting circuit begins time till experienced predefined specified time limit; Control circuit is used for after during above-mentioned the power consumption of receiver being reduced.

According to the present invention, for the selective call receiver, by making in through the time during the timing that sets it can regular event from detecting low-voltage, thereby can use battery to greatest extent, and, after during having experienced timing, reduce battery consumption, can prevent battery leakage.In addition, owing to use 1 voltage detecting circuit so can reduce cost.

Can understand above-mentioned and other purpose and feature of the present invention clearly from following description with reference to accompanying drawing.

Fig. 1 is the block diagram of the selective call receiver structure of one embodiment of the invention.

Below, utilize description of drawings one embodiment of the present of invention.In Fig. 1, the 1st, the antenna of reception wireless signal, the 2nd, amplify radio part from the wireless signal of antenna 1, the 3rd, the demodulation wireless signal is also made the demodulator of digital signal, the 4th, store the ID-ROM of self individual calling sequence number symbol, the 5th, storage package is contained in the RAM of the information in the received signal, the 6th, controller, in controller 6, the 7th, battery reservation function device, the 8th, the report controller of control report function, the 9th, the display controller that control shows, the 10th, the power consumption that control selective call receiver reduces power consumption reduces controller, the 11st, timer, the 12nd, setting apparatus during the timing, the 13rd, the timer controller, the 14th, the voltage detecting recognition memory, in addition, the 15th, detect the voltage detecting circuit that cell voltage or booster voltage descend, the 16th, amplify the driver of report drive signal, the 17th, loud speaker, the 18th, LED, the 19th, the display of display message, the 20th, the importation during the setting timing, the 21st, the element that needs are higher than cell voltage promotes the booster circuit of cell voltage, the 22nd, battery.

Below, describe with regard to the action of the foregoing description.Because the action of relevant radio selective calling is same as the prior art, so account for voltage control action only here.In a single day the output voltage of battery 22 or booster circuit 21 is lower than assigned voltage, and voltage detecting circuit 15 just detects it, voltage detecting recognition memory 14 its results of storage.This information is sent to report controller 8 and display controller 9, and driver 16 perhaps on the drawing of display 19, carries out respectively urging the 1st warning changing battery 22 owing to battery 22 voltages descend by loud speaker 17 and LED18.Information from voltage detecting recognition memory 14 also is sent to timing controller 13, by timing controller 13 starting timers 11.Timer 11 is according to 20 values of importing and setting the setting apparatus 12 during timing begin counting from the importation in advance.The counting of timer 11 reduces controller 10 arriving or send power consumption to through time during setting in the setting apparatus 12 during timing, power consumption reduces controller 10 starting battery reservation function devices 7, stop the action of radio part 2 and demodulator 3, carry out the action that reduces power consumption, and controller 8 and display controller 9 are reported in starting respectively, report to the police through driver 16 usefulness loud speakers 17 and LED18.Simultaneously, owing to for preventing that battery leakage from having stopped the action of receiver, so on display 19, urge the 2nd time of hastening to change battery to show.And then power consumption reduces the action of controller 10 control ID-ROM4 and RAM5, carries out the action that reduces power consumption.

In addition, action as further reduction power consumption, arrive or through during during timing, setting in the setting apparatus 12 time at the counting of timer 11, the action of report controller 8 and display controller 9 is also stopped, carrying out the action that reduces power consumption.

From above-described embodiment as can be known, since the present invention have monitoring battery voltage or monitor booster tension voltage booster circuit output voltage and detect the voltage detecting circuit of regulation low-voltage, detecting the regulation low-voltage from voltage detecting circuit to through timing circuit that carries out timing in the time of predefined specified time limit and the control circuit that reduces in the power consumption that makes receiver through the moment during this period, so can prevent from using the low quality battery not change immediately after low-voltage is reported to the police battery under the situation that uses the battery limit and do not note and the phenomenon of leakage that former state causes because of battery deterioration when placing.

In addition, according to the present invention, owing to carry out the transfer that power consumption after cell voltage reduces reduces state by timing, thus can be only with 1 voltage detecting circuit, thus reduce cost can be than 2 voltage detecting circuits of use the time.
