Abstract

The utility model discloses a power module of a handheld ultra-short-wave air control station. The power module is characterized by comprising a power supply, a power switching circuit, a voltage regulating circuit and a display unit used for displaying electric quantity. The power supply unit is composed of a power supply unit A that is a switch power source and a power supply unit B including a charging switch and a charging battery. The charging switch is connected with the charging battery through a charging chip. The power switching circuit is composed of a PMOSFET and a schottky diode. One output terminal of the charging battery is connected with a grid electrode of the PMOSFET while the other output terminal is connected with the display unit. An output terminal of the switching power source is connected with the grid electrode of the PMOSFET. The source electrode of the PMOSFET is connected with the voltage regulating circuit. The schottky diode is connected with the PMOSFET in parallel. By using the power module provided by the utility model, the charging battery of the handheld ultra-short-wave air control station can be charged conveniently. Since the power module is provided with the charging switch and the display unit, a user can judge whether to charge the handheld ultra-short-wave air control station or not conveniently.

Description

Hand-hold type ultrashort wave ground to air radio set power module
Technical field
The utility model relates to a kind of hand-hold type ultrashort wave ground to air radio set power module.
Background technology
Hand-hold type ultrashort wave ground to air radio set (hereinafter to be referred as: hand-held station), communicate by letter as main take speech (comprising encrypted word), in air defense control automated system, be also furnished with empty transfer of data radio station, for automatically and fast guiding many batches of targets of many batches of aircraft interceptions, meet civil aviaton's Speech Communication system, be applicable to drop from the air, drop, field task and the airport emergency guarantee etc. such as training be to sky guiding commander task.
Hand-held station is mainly used in the guiding to sky of following occasion and commands:
(1) command and guide of airborne, the airdrop mission of transporter;
(2) command and guide of the motor-driven landing of helicopter field, training, field task;
(3) the emergent command and guide in airport.
At present ultrashort wave frequency band hand-hold type ground to air radio set adopts imported product substantially, mainly contains the hand-held station such as IC-A24, IC-A3E of Japanese ICOM company etc.These products are mainly in outdoor application, and therefore hand-held station is generally to pass through lithium battery power supply.But when lithium battery does not have after electricity, need to be to lithium cell charging, if use hand-held station in the time of charging, battery can be hot, and use and also can cause certain damage to battery while filling, and shortens battery.Therefore, the power module of hand-held station need to improve further, to overcome above-mentioned deficiency.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of hand-hold type ultrashort wave ground to air radio set power module with duplicate supply unit is provided, and power supply unit A preferentially powers, and in the time that power supply unit A powers, can charge to power supply unit B, charging is convenient.
The purpose of this utility model is achieved through the following technical solutions: hand-hold type ultrashort wave ground to air radio set power module, it comprises power supply, power supply switch circuit, voltage-regulating circuit and for showing the display unit of electric weight, power supply unit is made up of power supply unit A and power supply unit B, power supply unit A is a Switching Power Supply, power supply unit B comprises charge switch and rechargeable battery, charge switch is connected with rechargeable battery by charging chip, power supply switch circuit is made up of PMOSFET and Schottky diode, the output of rechargeable battery Yi road is connected with the grid of PMOSFET, another road output is connected with display unit, the output of Switching Power Supply is connected with the grid of PMOSFET, the source electrode of PMOSFET is connected with voltage-regulating circuit, Schottky diode is parallel between the grid and source electrode of PMOSFET.
Described voltage-regulating circuit comprises DC/DC converter.
The beneficial effects of the utility model are:
1) duplex feeding design, in the time that power supply unit A powers, the grid voltage of PMOSFET, higher than its source voltage, in off state, thereby has cut off the connection of rechargeable battery, now, is directly powered to hand-held station by civil power.In the time removing civil power, PMOSFET conducting, is powered to hand-held station by rechargeable battery, is convenient to hand-held station user and selects, and when Schottky diode can prevent that rechargeable battery from powering separately, electric current flows into Switching Power Supply from rechargeable battery, has guaranteed that circuit normally works; Due to power supply switch circuit being set, when civil power is directly powered to hand-held station, can charge to rechargeable battery, two-way power supply is independent of each other, and charges convenient, easy to use, and owing to correctly battery being charged, has ensured the long life of rechargeable battery;
2) between civil power and charging chip, charge switch is set, even if charge switch is connected with civil power, whether hand-held station user also can select to charge, charging selectivity strengthens, and avoid high frequency plug power line to cause damage to hand-held station internal circuit or power line itself, charging operations is simple, convenient, has strengthened the practicality of hand-held station;
3) display unit is set, can shows the electric weight of rechargeable battery, the foundation that provides hand-held station whether should charge, is convenient to hand-held station user decision-making.
