The utility model discloses control by MCU main control chip can keep lower consumption, promotes battery time of endurance. With the LCD LCD demonstration, it is big, small to have the information quantity of demonstration, light in weight, and the consumption is lower, and is longe -lived, advantages such as convenient to use. The time sign indicating number receiving circuit use the discrete element, the electrical circuitry is simple, and is with low costs, but the adjustment is complicated, easily receives the interference. Adopt solar energy power supply system further to reduce the consumption.
Description
Technical field
The utility model relates to a kind of Wave timepiece, particularly relates to a kind of Micro Energy Lose radio-wave wristwatch.
Background technology
" Wave timepiece " is also a kind of " electronic watch ", and its basic timing principles is just the same with tradition " electronic watch ".Add radio system unlike radio controlled timepiece, be used for receiving electric wave time signals.Time signal is the time study mechanism broadcast of being entrusted by government, its time reference is atomic clock, atomic clock is the atomic oscillator that a precision and stability is very high, its accumulated error is generally in second in hundreds of thousands year one, maintain the standard time of country by the mode such as astronomical sight, international comparison simultaneously, and providing time service service with various means, electric wave time service is wherein a kind of.Existing Wave timepiece back light many employings LCD backlight, by defect in power consumption and backlight intensity, part uses the Wave timepiece of LED-backlit, and its power consumption control is also undesirable.The time-code receiving circuit of many Wave timepieces uses integrated amplifier, but needs to use positive-negative power, and gain bandwidth (GB) is limited, and power consumption is large, and cost is high.
Utility model content
The technical problems to be solved in the utility model, be to provide a kind of Micro Energy Lose radio-wave wristwatch, comprise MCU main control chip, Signal reception module, power converting circuit, solar power supply circuit and LCD display, described Signal reception module, power converting circuit and LCD display are connected with MCU main control chip and control by it, described power converting circuit is connected with solar power supply circuit, MCU main control chip and Signal reception module respectively, described solar power supply circuit comprises power management chip, and described output voltage of power management chip is 3.3V.
Further, described Signal reception module comprises the receiving antenna, prime selective frequency amplifier circuit, filtering circuit, output amplifier and the detecting circuit that connect successively.
Further, described MCU main control chip adopts model to be the single-chip microcomputer of STM32L152RBT6.
Further, described receiving antenna adopts the neutral bar magnet coiled antenna of 15mm length, and enameled wire coiling used by described neutral bar magnet.
The utility model can keep lower power consumption by the control of MCU main control chip, promotes battery life.With the display of LCD liquid crystal display, have display and contain much information, volume is little, lightweight, the advantages such as power consumption is lower, and the life-span is long, easy to use.Time-code receiving circuit uses resolution element, and circuit theory is simple, and cost is low, but adjustment is complicated, is easily disturbed.Solar electric power supply system is adopted to reduce power consumption further.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is the module diagram of Micro Energy Lose radio-wave wristwatch of the present utility model.
Embodiment
Refer to Fig. 1, it is a kind of Micro Energy Lose radio-wave wristwatch as most preferred embodiment of the present utility model, comprise MCU main control chip, Signal reception module, power converting circuit, solar power supply circuit and LCD display, described Signal reception module, power converting circuit and LCD display are connected with MCU main control chip and control by it, described power converting circuit is connected with solar power supply circuit, MCU main control chip and Signal reception module respectively, described solar power supply circuit comprises power management chip, and described output voltage of power management chip is 3.3V.Described Signal reception module comprises the receiving antenna, prime selective frequency amplifier circuit, filtering circuit, output amplifier and the detecting circuit that connect successively.By the 5V voltage that the battery in solar power supply circuit produces, power management chip HT7533 is used to transfer 3.3V to for single-chip microcomputer.This power management chip quiescent current only has 2uA, and power consumption is very low.Described MCU main control chip adopts model to be the single-chip microcomputer of STM32L152RBT6, this single-chip microcomputer has 7 kinds of low-power consumption modes, its lowest power consumption can reach 1uA, when the multiple clock of components of system as directed is opened, its controlled current flow is built in 5.1uA, during in complete machine dormancy with by light, by the power-off of receiver circuit and display device, thus reduce total system power consumption.Described receiving antenna adopts the neutral bar magnet coiled antenna of 15mm length, and enameled wire coiling used by described neutral bar magnet.Magnetic antenna around forming by a ferrite bar and line, can be induced higher HF voltage and have the effect of amplifying high frequency mark concurrently, can improve antijamming capability in coil winding.
The utility model can keep lower power consumption by the control of MCU main control chip, promotes battery life.With the display of LCD liquid crystal display, have display and contain much information, volume is little, lightweight, the advantages such as power consumption is lower, and the life-span is long, easy to use.Time-code receiving circuit uses resolution element, and circuit theory is simple, and cost is low, but adjustment is complicated, is easily disturbed.Solar electric power supply system is adopted to reduce power consumption further.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
