Description

Technical Field

[0001] The invention belongs to the technical field of aviation equipment and the technical field of artificial rainfall, and specifically designs an automatic spreading method for aircraft cold and warm cloud flame strips. Background Art

[0002] With the progress of science and technology and the needs of social development, artificial rainfall is increasingly being used in drought and flood control, forest fire prevention, major event support and even national defense, and the demand for more advanced rainfall equipment is also increasing. Aerial rainfall is a major development direction in the field of artificial rainfall, which has the advantages of strong mobility, large operating area, uniform seeding and wide range of influence, and has a very broad development prospect.

[0003] A major problem in rainmaking operations is that the temperature of the cloud layer in each area cannot be predicted in advance before the aircraft takes off. It is necessary to enter the cloud to actually collect data. According to different cloud conditions, cold cloud flame strips or cold and warm cloud flame strips are used to perform artificial rainmaking. Therefore, in existing aviation artificial rainfall operations, aircraft mixed with cold and warm cloud flame strips has become a frequently used mode. The problems and disadvantages of traditional aircraft mixed with cold and warm cloud flame strips are as follows:

[0004] 1) The aircraft flame strip spreading system has a low integration level, and requires manual recording of the filling channel, and even only one flame strip, cold cloud or warm cloud, can be selected for spreading;

[0005] 2) After the aircraft takes off, the cold and warm cloud flame strips need to be selectively spread according to memory;

[0006] 3) The amount of flame strips spread is small, the degree of automation is low, and there is a lack of reminders of the spread progress;

[0007] 4) The spreading system is complicated to operate and difficult for operators to master, which is not conducive to the accurate delivery of rain enhancers.

[0008] Therefore, in order to achieve artificial rainfall more accurately, efficiently and safely, a method for automatically spreading cold and warm cloud strips from aircraft is needed. To achieve this goal, it is necessary not only to improve the accuracy of cold and warm cloud strip recognition, but also to achieve precise spreading. Summary of the invention

[0009] In order to solve various problems existing in the spreading of cold and warm cloud flame strips in the prior art, the present application proposes a method that can realize automatic spreading of cold and warm cloud flame strips of aircraft in an aviation environment.

The ignition device in the channel is associated with the resistance identification electrode; 3) the flame bar execution controller obtains the resistance value of the flame bar in the flame bar spreading channel through the flame bar identification module, and identifies the flame bar filling status and the cold and warm cloud flame bar type in the spreading channel according to the resistance value, forms the flame bar filling status information and sends it to the display control computer; 4) the display control computer displays the flame bar filling status information of each flame bar spreading channel in three different colors in the flame bar spreading channel status diagram, one color shows that there is no flame bar loaded in the spreading channel, one color shows that the spreading channel is filled with cold cloud flame bars, and another color shows that the spreading channel is filled with warm cloud flame bars; 5) the operator selects the flame bar spreading channel to be spread according to the flame bar filling status information in the spreading channel status diagram to form a spreading instruction and send it to the flame bar ignition module of the flame bar execution controller, and the flame bar ignition module sends the ignition current to the ignition device of the flame bar spreading equipment to achieve the purpose of flame bar ignition and spreading.

[0011] The method for automatically spreading cold and warm cloud flame strips on an aircraft is characterized in that the flame strip filling status information contains whether each spreading channel is filled with flame strips, and whether the filled flame strips are cold cloud flame strips or warm cloud flame strips. If there are no flame strips filled in the spreading channel, the corresponding numbering mark of the display control computer in the flame strip spreading channel status diagram is gray; if the spreading channel is filled with cold cloud flame strips, the corresponding numbering mark of the display control computer in the flame strip spreading channel status diagram is blue; if the spreading channel is filled with warm cloud flame strips, the corresponding numbering mark of the display control computer in the flame strip spreading channel status diagram is yellow.

DETAILED DESCRIPTION

[0020] See the attached drawings. The aircraft cold and warm cloud flame strip automatic spreading system of the present application is suitable for aircraft cold and warm cloud flame strip spreading, and has automatic identification and automatic spreading functions. The system contains a display control computer, a flame strip execution controller and a flame strip spreading device. Figure 1As shown, the display control computer and the flame strip execution controller are arranged in the aircraft cabin 1, and a flame strip spreading device 2 is mounted on each side of the aircraft fuselage. Each flame strip spreading device 2 contains twenty flame strip spreading channels 4, and the bottom of each flame strip spreading channel 4 is provided with an independent ignition device 6 and an independent resistance value identification electrode 5. Cold cloud flame strips 7 or warm cloud flame strips 8 are randomly loaded in the flame strip spreading channel 4 of the flame strip spreading device 2. The flame strip execution controller is connected to the ignition device 6 and the resistance value identification electrode 5 of each flame strip spreading channel 4 of the flame strip spreading device 2 through the cabin wiring harness 3, so as to collect the resistance value of the flame strip in the spreading channel 4 and ignite and spread the flame strip.

[0021] The flame bar execution controller is installed in the aircraft cabin. The flame bar execution controller has a built-in flame bar identification module and a flame bar ignition module, and is connected to the ignition device and resistance identification electrode of each flame bar spreading channel of the flame bar spreading equipment through the cabin wiring harness. The flame bar execution controller obtains the resistance value of the flame bar in the flame bar spreading channel through the flame bar identification module. The resistance range of the cold cloud flame bar 7 is: 0.8~8Ω, and the resistance range of the warm cloud flame bar 8 is: 11~20Ω. The flame bar identification module realizes the accurate identification of the flame bar resistance value by software differential and filtering the flame bar resistance value, and identifies whether the flame bar is loaded, whether the loaded is a cold cloud or warm cloud flame bar, etc. The flame bar filling state and the cold and warm cloud type of the flame bar in the spreading channel are identified according to the resistance value, and the flame bar filling state information is formed and sent to the display control computer.

[0022] In the implementation, the display interface of the display control computer has a flame spreading channel state diagram (such as Figure 2 As shown), the flame strip spreading channel state diagram contains twenty numbered identifiers, which correspond one-to-one to the twenty flame strip spreading channels of the spreading device 2, so that each spreading channel has a unique corresponding numbered identifier.

[0023] The operator randomly loads the cold cloud flame strips 7 or the warm cloud flame strips 8 into the flame strip spreading channel 4 of the flame strip spreading device 2 , so that the cold cloud flame strips 7 or the warm cloud flame strips 8 are associated with the ignition device 6 and the resistance identification electrode 5 in the flame strip spreading channel 4 .

[0024] After the flame strips are loaded, the operator enters the work cabin and presses the "test" button. The flame strip identification module of the flame strip execution controller starts to query whether each flame strip sowing channel 4 of the flame strip sowing device 2 is loaded with flame strips, and whether it is a cold cloud flame strip or a warm cloud flame strip. The flame strip loading status and the flame strip cold and warm cloud types in the sowing channel are identified based on the resistance value, and the flame strip loading status information is sent to the display control computer; the display control computer displays the flame strip loading status information of each flame strip sowing channel in different colors in the flame strip sowing channel status diagram.

[0025] The display control computer displays the flame bar filling status information of each flame bar spreading channel in different colors in the flame bar spreading channel status diagram. In the embodiment, if there is no flame bar loaded in the spreading channel, the corresponding numbered mark in the flame bar spreading channel status diagram is gray; if the spreading channel is loaded with cold cloud flame bars 7, the corresponding numbered mark in the flame bar spreading channel status diagram is blue; if the spreading channel is loaded with warm cloud flame bars 8, the corresponding numbered mark in the flame bar spreading channel status diagram is yellow.

[0026] In the spreading channel state diagram, the operator selects the number mark of the flame bar spreading channel 4 to be spread according to the flame bar filling state information, and the display control computer adds an orange identification color ring 9 to the number mark of the flame bar spreading channel to be spread selected by the operator in the spreading channel state diagram to mark the selection. The display control computer forms a spreading instruction with the number mark of the flame bar spreading channel 4 to be spread and sends it to the flame bar ignition module of the flame bar execution controller, and the flame bar ignition module sends an ignition current to the ignition device 6 of the flame bar spreading device 2 to ignite the flame bar and spray catalytic smoke. The purpose of flame bar ignition and spreading is achieved.

[0027] The flame strip spreading device 2 ignites and spreads the selected flame strip spreading channel 4 in turn. After about three seconds, the flame strip execution controller reports the spreading status to the display control computer. After the display control computer receives the "spreading valid" status report of a flame strip spreading channel of the flame strip spreading device, the display control computer uses a gray sector-shaped decreasing timer 10 in the flame strip spreading channel status diagram to indicate the flame strip burning progress for the flame strip spreading channel number mark that is being ignited and spread. The decreasing timer for the cold cloud flame strip 7 is 25 minutes, and the decreasing timer for the warm cloud flame strip 8 is 18 minutes. After the decreasing timer ends, the orange ring of the spreading channel number mark disappears, and the spreading channel number mark becomes a gray mark without a flame strip filled. At the same time, the "spreading completed" prompt message will automatically pop up in the flame strip spreading channel status diagram to remind the operator that the spreading has ended.

[0028] In order to prevent operators from mistakenly operating the flame bar when the aircraft is on the ground, the spreading instruction issued by the display control computer is associated with the aircraft's wheel-loaded signal in the embodiment. When the aircraft's wheel-loaded signal shows that the aircraft is on the ground, the spreading instruction of the display control computer will not be passed to the flame bar ignition module of the flame bar execution controller, and a "Ground spreading prohibited" warning dialog box will be displayed on the spreading channel status diagram.
