Description
Technical Field
The invention belongs to the technical field of artificial precipitation equipment and aviation equipment, and particularly relates to an artificial precipitation agent spreading system for an airplane and a control method.
Background
With the needs of scientific and technological progress and social development, artificial precipitation is more and more commonly applied to the fields of drought resistance, waterlogging prevention, forest fire prevention, major activity guarantee and national defense, so that the demand for more advanced precipitation equipment is continuously increased. Aviation rain enhancement is a great development direction in the field of artificial rain enhancement, has the advantages of large monitoring area, high rain enhancement agent scattering precision, capability of scattering while monitoring, capability of tracking rain and cloud accumulation action and the like, and has very wide development prospect.
The great difficulty of the rain enhancement operation is how to accurately and timely spread the rain enhancement agent into the accumulated rain clouds. This is because the composition of the cloud in the atmosphere is very complex, and many factors such as its moisture content, ice crystal size, average temperature, etc. affect rainfall, and under the influence of wind, all of this changes very rapidly. Moreover, some data, such as the size of ice crystal particles, cannot be accurately measured on the ground, and must be actually collected in the cloud. Therefore, in the existing aviation artificial rainfall operation, a detector is generally required to detect weather conditions firstly to judge whether the rainfall requirement is met, and then another airplane (or the detector takes off after landing) carries a suitable rainfall enhancer according to the detected weather conditions and flies to a target area for scattering operation.
In this process, the selection and distribution of the type of rain-enhancing agent is also a highly specialized task. Rain enhancers used in aviation rain enhancement can be classified into four major categories in terms of type: a flame strip rain enhancer, a flame bomb rain enhancer, a cold cloud rain enhancer and a warm cloud rain enhancer. The main differences are as follows: the flame strip rain-increasing agent releases components required for increasing rain through continuous combustion, is fixed on an airplane during combustion, moves along with the airplane, and is suitable for increasing rain in a cloud layer with a large area. A flame bomb rain enhancer: the components required for rain enhancement are released through continuous combustion, can be thrown out of the airplane after being ignited, move in a free-falling body during combustion, and are suitable for rain enhancement of thick cloud layers. A warm cloud rain-increasing agent: is a powdery reagent which can float with wind after being sowed and is suitable for accumulated rain clouds higher than 0 degree. Cold cloud rain machine: is suitable for accumulated rain clouds below 0 degree, and is dispersed with wind power after being sown, and is a liquid reagent. Obviously, different kinds of rain enhancers cannot be stored together, and the spreading conditions are different.
Therefore, in order to realize artificial precipitation more accurately and timely, an artificial precipitation machine with complete functions is needed. To achieve this, it is necessary to install the atmospheric detection system and the aircraft artificial precipitation agent spreading system on the same aircraft, and to achieve high integration of the two systems. On the existing rain-increasing airplane, the integration level of the airplane artificial rain-increasing agent spreading system is very low, and the spreading of all rain-increasing agents is often controlled by depending on various spreading equipment controllers respectively, even only one rain-increasing agent can be spread. Meanwhile, the problems of single sowing mode, low automation degree, multiple manual intervention, lack of margin reminding and the like exist. This causes the current system of scattering not only complex operation, and it is difficult to master, also is not favorable to accurate realization to increase rain agent and puts in.

The connection relationship is as follows: the two automatic control computers are connected with each other through the Ethernet; two automatic control computers are respectively connected with a flame bomb rain enhancement agent spreading controller, a flame strip rain enhancement agent spreading controller, a cold cloud rain enhancement agent spreading controller and a warm cloud rain enhancement agent spreading controller through a manual automatic control change-over switch by using one RS485 bus. The manual spreading controller is connected with the flame bomb rain-increasing agent spreading controller, the flame strip rain-increasing agent spreading controller, the cold cloud rain-increasing agent spreading controller and the warm cloud rain-increasing agent spreading controller respectively through a RS485 bus and a manual automatic control change-over switch. The flame bomb rain enhancement agent spreading controller is connected with the flame bomb rain enhancement agent spreading equipment through a digital signal bus. The flare rainfall agent scattering controller is connected with the flare rainfall agent scattering equipment through a digital signal bus. The cold cloud rain increasing agent sowing controller is connected with the cold cloud rain increasing agent sowing equipment through a digital signal bus. The warm cloud rain-increasing agent sowing controller is connected with the warm cloud rain-increasing agent sowing device through a digital signal bus. The electrical connection mode of the whole system can be seen in fig. 1. Through the structural design of the system, the aircraft artificial precipitation agent spreading system disclosed by the specification is characterized in that the whole system is highly integrated. In use, an operator can realize the spreading control of the four rain enhancers by operating any one of the two automatic control computers and the manual spreading controller.
The airplane artificial precipitation increasing agent spreading system has the precipitation increasing agent spreading control function, and precipitation increasing agent spreading control can be realized on a first automatic control computer, a second automatic control computer and a manual spreading controller. The operator can decide whether to control by two automatic control computers or a manual seeding controller through a manual automatic control change-over switch. When the switch is arranged on the 'automatic' side, the control signals from the first automatic control computer and the second automatic control computer are simultaneously switched on, and at the moment, each sowing controller simultaneously receives the control signals from the two automatic control computers. The first automatic control computer and the second automatic control computer are in a level relation in control, no priority command exists, and both can send commands to the spreading control equipment through the RS485 bus. The rainforcing agent spreading control interfaces of the two automatic control computers are completely the same, and the two computers are connected with each other by using the Ethernet, so that the display data of the rainforcing agent spreading control interfaces are ensured to be consistent. When the switch is placed on the "manual" side, the control signal from the manual broadcast controller will be turned on, and each broadcast controller will only receive the signal from the manual broadcast controller.
The airplane artificial precipitation increasing agent spreading system has precipitation increasing agent residual quantity display function, the residual quantity of precipitation increasing agent can be displayed on the first automatic control computer, the second automatic control computer and the manual spreading controller, but the display mode on the manual spreading controller is different from that on the automatic control computer. The specific display mode is as follows: the number of un-ignited rain enhancement flares and the location of these flares in the device for spreading the rain enhancement agent to the flares are shown. The number and position of the un-ignited flame strips, the amount of combustion of the ignited flame strips and the remaining combustion time are shown. The total inventory of cold cloud rainforcing agent and the balance of rainforcing agent in each storage tank are shown as percentages. The total inventory of warm cloud rainforcing agent and the balance of rainforcing agent in each storage tank are shown as percentages. The residual amount information of the rain-increasing agent is detected by a sensor arranged on each spreading device, and the detection result is transmitted back to a rain-increasing agent spreading controller of each device. The detected data is converted into the residual rain-increasing agent information by each controller, and then the residual rain-increasing agent information is uploaded back to the automatic control computer and the manual sowing controller.

And finally, displaying the self-test result on the automatic control computer and the manual controller. The self-checking information may be that the equipment starts checking according to a certain logic, or that an operator actively sends a self-checking command.

The airplane artificial precipitation increasing agent spreading system has the precipitation increasing agent spreading control function, the spreading control can be realized on an automatic control computer and a manual spreading controller, but the control mode on the automatic control computer is different from that on the manual spreading controller.

Two automatic control computers and a manual controller. Which are respectively connected with other devices through one path of RS485 bus signal. The bus of the first automatic control computer is marked as RS485-1, the bus of the second automatic control computer is marked as RS485-2, and the bus of the manual controller is marked as RS 485-3. The first computer and the second computer are connected with each other through the Ethernet. The automatic control computer is provided with a spreading control software, and an operator selects the type of the rain-increasing agent and the spreading mode through the software, generates a control signal in an RS485 bus format and outputs the control signal. The software can also realize information synchronization between the two automatic control computers through the Ethernet, and the consistency of the display information on the two automatic control computers is ensured. The manual controller is provided with a control button, and the rain-increasing agent type and the spreading mode can be selected through the button.

Wherein RS485-1 and RS485-2 share the "automatic" end of the switch, and RS485-3 uses the "manual" end of the switch. When the switch is arranged at the 'automatic' end, the RS485-1 and the RS485-2 are connected, the automatic control computer obtains the control right, the two automatic control computers can send control instructions to the respective rainincreasing agent sowing controllers, and the manual controller fails.

At the moment, the automatic control computer is effective, and an operator can select a 'flame strip/firework' sub-interface on the broadcast control interface and know the number and the state of the remaining fireworks in the system at present through color marks on the interface. The operator can press the self-checking button to initiate a new self-checking operation, and the equipment returns a self-checking result after several seconds and refreshes the display. After the required sowing quantity, sowing interval and sowing mode are input in the sowing condition input frame, the 'sowing' button is pressed, and then the sowing of the flare rain-increasing agent can be started. If the operator changes the idea during the sowing process, the sowing can be stopped by pressing the 'stop' button. When the set sowing is finished, the prompt message can automatically jump out to remind an operator that the sowing is finished.

At the moment, the manual controller is effective, and an operator can press a page left or right button to find and check the residual amount and state of the flame bomb rainforcing agent in the system on a liquid crystal display screen of the manual controller. And then, a preset spreading mode can be appointed by rotating the 'flame bar' knob, and then the 'spreading' button is pressed to start spreading of the flame bar rain enhancer. If the operator changes the idea during the sowing process, the sowing can be stopped by pressing the 'stop' button.
