Description

Technical Field

[0001] The invention belongs to the technical field of aircraft electrical control, and relates to a parachute indication control circuit, in particular to a one-button parachute indication device with a reset function. Background Art

[0002] Usually the parachute jump indication control circuit of the parachute jump configuration aircraft is as follows Figure 1 As shown, it consists of 3 control switches and control circuits. The first switch of the green parachute indicator light is a single-pole double-throw switch, the switch A contact is connected to the 28VDC power supply, and the B contact is connected to the green parachute indicator light 4 and the alarm 5; the second switch of the yellow parachute indicator light is a single-pole double-throw switch, the switch A contact is connected to the 28VDC power supply, and the B contact is connected to the yellow parachute indicator light 6; the third switch of the red parachute indicator light is a single-pole double-throw switch, the switch A contact is connected to the 28VDC power supply, and the B contact is connected to the red parachute indicator light 7. The second ends of the three parachute indicator lights are grounded respectively.

[0003] Its working principle is that when the A contact and the B contact of the first switch of the green parachute indicator light are connected, the green parachute indicator light 2 and the alarm 3 are connected with positive electricity, the green parachute indicator light 4 lights up, and the parachute alarm 5 continues to emit a parachute reminder sound; when the A contact and the C contact of the first switch of the green parachute indicator light are connected, the green parachute indicator light 4 goes out, and the alarm 5 stops emitting a parachute reminder sound; when the A contact and the B contact of the second switch of the yellow parachute indicator light are connected, the yellow parachute indicator light 6 is connected with positive electricity, and the yellow parachute indicator light 6 lights up; when the A contact and the C contact of the second switch of the yellow parachute indicator light are connected, the yellow parachute indicator light 6 goes out; the control principle of the red parachute indicator light is the same as that of the yellow parachute indicator light.

[0004] The disadvantage is that the three parachute indicator light switches independently control the corresponding parachute indicator lights. When a certain indicator light needs to be turned on, another indicator light that is on must be turned off manually. When emergency parachuting needs to be stopped, two steps are required to achieve it. The yellow or green indicator light must be turned off manually first, and then the red indicator light is turned on. At the same time, the indicator lights lack a mutually exclusive function, which is prone to misoperation and causes multiple indicator lights to light up at the same time, increasing the risk of parachuting operations. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a one-key parachute indication device with a reset function, which realizes the pilot's one-key control of the parachute indication, adds the mutually exclusive logic of the parachute indicator light, fundamentally avoids the possibility of multiple indicator lights being lit, and also realizes the pilot's one-key reset of the parachute indication system.

[0006] The technical solution of the present invention is as follows:

[0007] A one-button parachuting indicator device with a reset function uses a first button, a second button and a third button that are logically mutually exclusive to control a parachuting indicator light, including: after the first button is pressed, the green light is lit; at the same time, the yellow light and the red light are turned off; after the second button is pressed, the yellow light is lit, and at the same time, the green light and the red light are turned off; after the third button is pressed, the red light is lit, and at the same time, the green light and the yellow light are turned off.

[0008] Furthermore, the system also includes using a reset button to control the parachuting indicator light. After pressing the reset button, the green light, the yellow light and the red light are all turned off.

[0009] Furthermore, it includes using control relay No. 1, control relay No. 2, control relay No. 3 and reset relay; after the first button is pressed, control relay No. 1 is controlled to be connected; after the second button is pressed, control relay No. 2 is controlled to be connected; after the third button is pressed, control relay No. 3 is controlled to be connected; after the reset button is pressed, the reset relay is controlled to be connected.

[0010] Furthermore, when control relay No. 1 is turned on, the contacts between the power supply and the green light are connected; at the same time, the power supply is connected between the first button and control relay No. 1 through the contacts controlled by control relay No. 2, control relay No. 3 and reset relay in sequence; the other contacts of control relay No. 1 are disconnected.

[0011] Furthermore, when control relay No. 2 is turned on, the contacts between the power supply and the yellow light are connected; at the same time, the contacts controlled by control relay No. 1, control relay No. 3 and reset relay are connected between the second button and control relay No. 2; and the other contacts of control relay No. 2 are disconnected.

[0012] Furthermore, when control relay No. 3 is turned on, the contacts between the power supply and the red light are connected; at the same time, the contacts controlled by control relay No. 1, control relay No. 2 and reset relay are connected between the third button and control relay No. 3; and the other contacts of control relay No. 3 are disconnected.

[0013] Further, when the reset relay is turned on, all contacts of the reset relay are disconnected.

[0014] Furthermore, the green light is connected in series with an alarm.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention realizes a novel aircraft parachute indication system control circuit by forming logic with four control buttons and four relays. The control circuit realizes one-key operation of the aircraft parachute indication system, and reduces the operation steps of controlling a certain parachute indicator light to turn off and controlling another parachute indicator light to light up from multiple steps to one step, thereby reducing the danger to parachuting personnel caused by the pilot operating the parachute indication system for too long. At the same time, the control circuit adds the mutually exclusive logic of the parachute indicator light to fundamentally avoid the situation where multiple parachute indicator lights are lit up at the same time due to the pilot's misoperation, thereby reducing the possibility of danger caused by the pilot's improper operation of the parachute indication system during the parachute operation.

[0017] 2. This control circuit reduces the step of observing the position of the parachute indication switch when resetting the aircraft parachute indication system, realizes one-button reset of the system, improves the operation rate of the aircraft parachute indication system, and further improves the safety of parachute operations. In actual use, the time for pilots to operate the parachute indication system can be reduced by 70%, and the danger caused by misoperation of multiple indicator lights can be 100% avoided.
