Description
Technical field
The utility model relates to a kind of control system, more specifically relates to a kind of DF37 millimeter antiaircraft gun tele-control system, can the transmitting of Long-distance Control 37 millimeters of antiaircraft guns, improves hail-proof rain-increasing operational security and operating efficiency.Be applicable to hail-proof rain-increasing 37 millimeters of antiaircraft guns.
Background technology
37 millimeters of antiaircraft guns are that China increases the main tool of rain for Artificial Hail Suppression, and quantity is many, distribution is wide.According to statistics in 2013, there were 7000 multi-door antiaircraft guns in the whole nation, and for hail-proof rain-increasing operation, firing shells every year on average and reach more than 100 ten thousand, is indispensable powerful of preventing and reducing natural disasters.This antiaircraft gun adopts manual operation, generally needs 4 ~ 6 people.Along with increasing of China's diastrous weather in recent years, the frequency of hail-proof rain-increasing operation is also in continuous increase, and the contradiction run in operation also progressively displays.One is that job safety accident occurs frequently, and a lot of barrel bore premature accident occurs for continuous 3 years in the whole nation, brings the injures and deaths of operation gunner.In gunner and administrative staff, produce the feared state of mind and mental burden, personal safety to have become in hail-proof rain-increasing operation distinct issues the most.Two is hand-filling shell speed and the spatial domain of short duration actual needs that can not meet hail-proof rain-increasing given launch time.Especially sleet-proof work adopts the mode of large bullet amount, the mass of fire mostly.Usually, a Hail Cloud By Using Weather synoptic process, needed transmitting 80 ~ 100 to fire bullet within 1 minute.Maximum needs transmitting 200 multiple, and minimum also will launch 30 ~ 50, and this just requires that 2 gunners ceaselessly operate on big gun.Three is along with national economic development, and domestic air mail device quantity and course line are being on the increase, and is also increasing in operation process to the difficulty in spatial domain control department application spatial domain.According to statistics, the spatial domain time that the every subjob of the operation shot point of most laboratories allows generally only has 0.5 ~ 1 minute.Artificial filling shell speed is slow, the spatial domain time shortly defines contradiction with the actual needs of hail-proof rain-increasing operation, thus have impact on operation effectiveness.Three, current hail-proof rain-increasing operating type can be divided into
Two kinds of situations: 1., after being judged according to the data analysis that radar provides by command centre, provide firing angle, azimuth roughly to shot point and the job parameters such as number that fire shells, shot point operates according to practical experience.2. the instruction of fishing time is only assigned by command centre to shot point according to the weather data that radar provides, and concrete job parameter is operated according to experience (time that such as hail is formed, path etc.) in the past by shot point.As can be seen here, the most of area of current China is also in experience sessions.4th, according to " Antiaircraft Artillery Artificial Hail Suppression artificial rain operation business norms (trying) ", the operational method of antiaircraft gun has: fixed point shooting and gradient shooting combination of leaning forward, grazing fire combination, concentric circles shooting combination, fan-shaped fixed fire etc. multiple (general designation Mode Launch).It determines different gunnery techniques and different bullet number according to different cloud bodies, and last firing operation is by completing manually, and its roughening and randomness are as can be seen here.
