Detailed description of the invention
Fig. 1 is monocell air-drop signal activation circuit system schematic diagram of the invention.
Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to of the invention
Specific embodiment is described in further detail.
As shown in Figure 1, the invention mainly comprises double-pole switch mode control switch K1, air-drop discharge cock K2, power supply are total
Switch K3, relay J1, relay J2, control unit ECU and air-drop mode indicating lamp K；
Double-pole switch mode control switch K1 (in panel, for daily and air-drop pattern switching), drops discharge cock K2
(outside equipment, being activated automatically when for dropping out cabin), battery main switch K3 (original equipment panel, and a route out, relay
J2 facilitates personnel to operate for shielding air-drop switch state after landing)；Relay J1 drops power source active relay, K2's
When pin is extracted, normally opened is closed the switch, and can be powered on for control unit ECU；Control unit ECU provides the switch position of acquisition K1
It sets, the timing commencing signal of K2, the distribution task of timing in 200 seconds and load (positioning device).It is described in detail as follows:
Increase an air-drop discharge cock K2 in outside vehicle, there is normally closed and normally open two contacts, after air-drop, the guarantor
The pin that nearly switchs is extracted, and normally closed switch may be implemented and open, and normally opened closes the switch, for realizing power supply switching and prolong
The flag bit of Shi Shang electricity.
In the grid-connected switch K1 of the accessory power supply of aerial delivery provisions instrument panel position arrangement, it is double-pole two-position switch, is divided into
Daily and air-drop two states, may be implemented air-drop and the switching of daily mode；In the output end of battery main switch K3, parallel connection one
Road positive supply may be implemented to relay J2 in the case where battery main switch K3 is closed, shielding air-drop discharge cock K2 control
Relay J1 influence.
The air-drop mode indicating lamp K is set, and when the grid-connected switch K1 of accessory power supply is in air-drop mode, control system exists
It is lighted in the case where having power supply.Flicker cycle 2Hz, prompt person close air-drop mode in time, avoid two-wire control equipment to electric power storage
The influence in pond.
The main operation modes of above-mentioned air-drop signal activation system include:
1) when the daily mode of the grid-connected switch K1 of accessory power supply is true, power supply system is one wire system, and battery main switch K3 is closed
J2 is connected after conjunction, and (switch, which is inserted into or is not inserted into, not to be influenced aerial delivery provisions and make for influence of the shielding air-drop discharge cock K2 to system
With being mainly used for the debugging that equipment such as is packaged at the stages), at this point, after control unit ECU is powered on, acquire the grid-connected switch of accessory power supply
The daily mode signal of K1 is very, to default distribution to positioning device, be not delayed.
In the case where signal activation system is dropped as one wire system, after battery main switch K3 is disconnected, system cut-off makes to be conventional
Use state.
2) the air-drop mode of the grid-connected switch K1 of accessory power supply is true, and power supply system is double wire system.Battery main switch K3 is disconnected
The case where, the pin insertion of K2, the ground of J1 control loop disconnects, and air-drop signal system power-off is in ready mode, lossless at this time
Electric loading is connected, it is ensured that the prolonged inventory of equipment waits air-drop.When the pin of K2 is freed, the ground of J1 control loop is connect
Logical, control unit ECU is powered on.Control unit ECU detect the air-drop mode of K1 be very after, into air-drop power up mode, control
Unit ECU starts to monitor the normally closed switch signal of K2, and pin K2 frees, and control unit ECU starts timing in 200 seconds, waiting air-drop
Equipment landing.After the completion of timing, positioning device is connected；Countdown logic is connected in control unit ECU activation at this time, is closed after 1 hour
The load of positioning device two-way is closed, aerial delivery provisions power supply is protected, avoids over-discharge.
3) to avoid after air-drop equipment from being chronically at the operating condition of double wire system and power on again and in the case that pin is not inserted into
It can false triggering air-drop signal activation system logic.Setting air-drop mode indicating lamp K mono-, when K1 is in air-drop mode, control
System is lighted in the case where having power supply, and flicker cycle 2Hz, prompt person closes air-drop mode in time, is by two-way load transfer
It is controlled by battery main switch K3.
As can be seen that invention introduces electrical circuits on the relay J1 of air-drop discharge cock K2 control, it can be achieved that signal
With the automatic collection and connection under power supply and air-drop state；Mode selector switch K1 is introduced, with realizing double wire system with one wire system
Switching, and provide type collection for control unit ECU；Devise the dual control based on mode switch K1 and air-drop discharge cock K2
Timing logic is dropped, avoids control unit ECU after control discharge cock K2 pin is extracted, the mistake after airborne landing is sentenced
It is disconnected.The setting of relay J2 can effectively ensure that in the case where aerial delivery provisions power on, air-drop signal activation system is not dropped
The influence of discharge cock K2；This programme is based on aerial delivery provisions and starts battery realization, does not increase additional battery, entirely when work
Between power consumption be less than 5Ah, have apparent advantage in weight.Therefore, before air-drop signal activation system of the invention solves air-drop
The life problems and charge and discharge problem of the problem of personnel operate power-supply system afterwards and air-drop power-supply system.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
