Description
Technical field
The present invention relates to a kind of low voltage warning method of electronic wave clock and device thereof.
Background technology
Radio wave clock is that a kind of radiotelegraphy, time-frequency technology, microelectric technique, computer technology of collecting is the timing product of new generation of one.Because inner MCU meeting automatic reception ratio long wave signal, and acquisition standard time information refreshes the time when walking behind the demodulating and decoding; Simultaneously, for indicator type electric wave clock, what need that locating device independently finishes pointer initially looks for the position, and gear case also has more very much not in common crystal clock and is same as.Therefore, compare with common crystal clock, the current drain of radio wave clock is also bigger.When the supplying cell consumption of radio wave clock is big, because supply voltage is low excessively, can occur losing the step when gear case is walked, stopping walking, it is undesired that LCDs shows, even radio wave clock appears when the machine phenomenon, thereby, influence the normal use of radio wave clock, stay bad product impression to the client, influence popularizing and promoting of radio wave clock.
Technology contents
For avoiding the defective of prior art, the present invention proposes a kind of radio wave clock low-voltage detects and alarming method for power method and device thereof, under the radio wave clock normal condition, compare by the supply voltage of built-in MCU detection radio wave clock and with the magnitude of voltage of stipulating, when detecting the magnitude of voltage that supply voltage is lower than regulation, start low voltage warning, when being implemented in power voltage insufficient, remind the user in time to change battery.
For achieving the above object, the technological means of the present invention's employing is:
The invention is characterized in: set a low-voltage flag storer, when built-in MCU detected magnitude of voltage that supply voltage is lower than regulation and surpasses 1 minute, set low-voltage flag storer was a low-voltage.After indicator type electric wave clock detects low-voltage (tag memory is a low-voltage), when walking at every turn to one of clock face fixedly scale place (the present invention adopted 00 second), indicator type electric wave clock can stop to walk the several seconds (the present invention adopts and stopped 5 seconds), recover fast then and stop walking the time and when normally walking, warn the user with this and in time change battery.
A kind of low voltage warning is for adding a hummer, after indicator type electric wave clock detects low-voltage (tag memory is a low-voltage), to one of clock face fixedly scale place (the present invention adopted 00 second), hummer can ring and make a noise one, warns the user with this and in time changes battery when walking at every turn.
Another kind of low voltage warning is for adding a bulb or light emitting diode, after indicator type electric wave clock detects low-voltage (tag memory is a low-voltage), when walking at every turn to one of clock face fixedly scale place (the present invention adopted 00 second), bulb or light emitting diode can be once glittering, warn the user with this and in time change battery.
Another kind of low voltage warning, it is low-voltage that liquid crystal display formula radio wave clock detects the low-voltage flag storer, LCDs can be warned the user with this and in time change battery once to carry out full frame flicker p.s..
The present invention's superiority compared to existing technology is: realized that it is low excessively cell voltage to occur after radio wave clock uses certain hour, reminded the user in time to change battery not causing fault to take place.Thereby, eliminate because the operational failure that radio wave clock supplying cell factor causes.

Embodiment
Further the present invention will be described below:
At first, compare,, start low voltage warning, remind the user in time to change battery when being implemented in power voltage insufficient when detecting the magnitude of voltage that supply voltage is lower than regulation by the supply voltage of built-in MCU detection radio wave clock and with the magnitude of voltage of stipulating.
Referring to Fig. 1, Fig. 2, MCU can utilize the function of tonic chord chip of radio wave clock itself, wherein the delivery outlet SEC+ of built-in MCU and SEC-are connected in gear case step motor second SEC MOTOR, the delivery outlet MIN+ of built-in MCU and MIN are connected in gear case time-division step motor MIN MOTOR, when built-in MCU is normally walked by an output stepping pulse signal control second motor.Detect low-voltage at built-in MCU,, stop to export stepping pulse signal so that a second motor stopped stepping 5 seconds when MCU normally walks time to 00～04 second; When normally walking time to 05 second, MCU control fast 5 stepping pulse signals of output so that second motor fast forward stepping recovered in 5 seconds and stop walking the time, warn the user with this and in time change battery.
Referring to Fig. 2, a kind of low voltage warning is for adding a hummer BZ, hummer BZ one termination power positive pole wherein, the collector of another termination triode Q1.The base stage of triode Q1 is connected to the output pin BZ of built-in MCU by a current-limiting resistance R1, and the emitter of triode Q1 connects power supply ground.Built-in MCU detects the magnitude of voltage that supply voltage is lower than regulation, when being the radio wave clock low-voltage, MCU exports the base stage of the 2KHz pulse signal of about half second to triode Q1 by delivery outlet BZ, triode Q1 conducting, hummer BZ obtains one and drives the 2KHz pulse signal that amplifies, buzzer call one is warned the user with this and is in time changed battery.
Referring to Fig. 2, a kind of low voltage warning is for adding a bulb or light emitting diode D1, and wherein D1 one end is connected to positive source by a current-limiting resistance R3, the collector of another termination triode Q2.The base stage of triode Q2 is connected to the output pin OUT2 of built-in MCU by a current-limiting resistance R2, and the emitter of triode Q2 connects power supply ground.Built-in MCU detects the magnitude of voltage that supply voltage is lower than regulation, when being the radio wave clock low-voltage, MCU is by the base stage of the about half second high level of delivery outlet OUT output to triode Q1, triode Q1 conducting, light emitting diode D1 can be once glittering, warns the user with this and in time change battery.
Another kind of low voltage warning, it is low-voltage that liquid crystal display formula radio wave clock detects the low-voltage flag storer, LCDs can be warned the user with this and in time change battery once to carry out full frame flicker p.s..
