FIELD: measurement equipment.SUBSTANCE: invention relates to the field of diagnostic equipment and may be used for systematic remote monitoring of condition of manifold gas mains and depots, namely, for early detection of loss of sealing, damages and leakages in the gas main, and is aimed at provision of better conditions of monitoring completion, increased efficiency and validity of measurement of parameters of gas mains condition, provision of the possibility for good landing of a remotely piloted aircraft by autonomous determination of its module of speed vector and drift angle, which is provided due to the fact that according to the invention the remotely piloted aircraft is equipped with a correlation metre of speed connected to a radio station of a radiotelemetering system connected with the control unit by on-board systems and made in the form of a transmitter with a transmitting antenna and three receives with receiving antennas, besides, to the outlet of the first receiver the following components are connected in series: the first multiplier, the second inlet of which via the first unit of controlled delay is connected with the outlet of the second receiver, the first low pass filter and the first extreme controller, the outlet of which is connected with the second inlet of the first unit of controlled delay, to the second outlet of which the first speed indicator is connected, to the outlet of the first receiver the second multiplier is connected in series, and its second inlet via the second unit of controlled delay is connected with the outlet of the third receiver, the second low pass filter, and the second extreme controller, the outlet of which is connected with the second inlet of the second unit of controlled delay, to the second outlet of which the second speed indicator is connected, the transmitting and receiving antennas are made as trumpet ones, the antenna pattern of the transmitting trumpet antenna is directed vertically downwards, the antenna patterns of receiving trumpet antennas are somewhat displaced, so that all antennas cover one and the same section on the earth surface, along the longitudinal base on board the first receiving antenna and the transmitting antenna are placed at the distance d/2, where d- length of the longitudinal base, with the first and second receiving antennas the first receiving base is formed, the first and third receiving antennas form the second receiving base, receiving bases are turned at the angle 2?, where ? - angle between the longitudinal base and the receiving base, the second and third receiving antennas are placed at the distance b, where b - the transverse base.EFFECT: improved conditions for monitoring completion, increased efficiency and validity of parameters of gas mains condition, provision of the possibility for good landing of a remotely piloted aircraft.7 dwg |
