Abstract
The utility model relates to an electricity storage modem, which solves the problem that a modem can not work during power failure. A rechargeable battery and a charging and discharging control circuit are additionally arranged inside the modem, wherein an input end of the charging and discharging control circuit is electrically connected with an access end of an external DC power supply of the modem correspondingly, control ends of the charging and discharging control circuit are electrically connected with positive and negative electrodes of the rechargeable battery correspondingly, and an output end of the charging and discharging control circuit is electrically connected with a power input end of an original circuit board inside the modem correspondingly. When power is available, the external power supply provides power for the modem on the one hand, and charges the battery inside the modem on the other hand; and during power failure, the rechargeable battery inside the modem provides power for the modem, and enables the modem to work continuously, thereby solving the problem that the network can not be accessed during power failure.
Description
Technical field:
The utility model relates to network equipment modulator-demodulator, especially a kind of accumulate modulator-demodulator.
Background technology:
The modulator-demodulator that family online is at present used does not have built-in rechargeable battery, just can't work in case have a power failure, and brings difficulty to family online.
Summary of the invention:
For a kind of modulator-demodulator of the endure that has a power failure is provided to people, the utility model provides a kind of accumulate modulator-demodulator.
The technical solution of the utility model: accumulate modulator-demodulator, inside at modulator-demodulator increases rechargeable battery and charge-discharge control circuit, the corresponding electrical connection of incoming end of the input of charge-discharge control circuit and modulator-demodulator external direct current power supply, the corresponding electrical connection with the both positive and negative polarity of rechargeable battery of the control end of charge-discharge control circuit, the output of charge-discharge control circuit and the inner corresponding electrical connection of power input of circuit board originally of modulator-demodulator, rechargeable battery and charge-discharge control circuit place circuit board all are fixed on the inside of modulator-demodulator.
Beneficial effect: use the accumulate modulator-demodulator, when electricity, external power supply supplies modulator-demodulator to modulator-demodulator on the one hand, gives the battery charge of modulator-demodulator inside on the other hand; During power failure, the rechargeable battery of modulator-demodulator inside is powered to modulator-demodulator, and modulator-demodulator still can be worked on, and has solved the problem that has a power failure and could not get on to the Net.
Description of drawings:
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is schematic diagram of the present utility model.
