Technical Field

The invention belongs to the field of underwater weapon submarine cloth launching, and particularly relates to a submarine launching tube speed testing system for a self-starting measuring platform.

Background

When underwater weapons such as torpedo mines and the like are launched by adopting submarines, the safety time and the safety distance need to be evaluated according to the water outlet speed of the platform. The platform also needs to be designed for platform safety based on the exit tube speed. Therefore, it is necessary to measure the velocity of the submarine launch tube at the platform.

At present, the domestic measurement of the speed of the submarine launching tube mainly depends on an infrared detection device fixed at the exit of the submarine launching tube. This is inconvenient because not every submarine is equipped with such a measuring device and requires regular maintenance. In addition, the device can only measure the average speed of the platform in the pipe outlet process, and cannot obtain the real-time speed result in the pipe outlet process.

Furthermore, the shell is a cylinder, the lower end face of the cylinder is provided with 6 through holes with the diameter of 5.5mm, and the through holes are fixed with the platform by 6M 5 screws; the triaxial acceleration sensor is fixed to the housing by an M4 screw.

Furthermore, the water pressure switch is fixed on the side shell of the platform in a radial sealing mode, and the end face of the water pressure switch sensing water pressure is flush with the surface of the platform shell.

Furthermore, the Hall switch is connected with a pin puller, and when the pin puller is connected with the Hall switch, the Hall switch is in a disconnected state; when the pin puller and the Hall switch are separated, the Hall switch is in a switch-on state.

Further, the water pressure switch has 2 outgoing lines: lead-out wire 1, lead-out wire 2, the panel plug has 2 pins: pin 1, pin 2, hall sensor have 2 outgoing lines: lead 1, lead 2; an outgoing line 1 of the water pressure switch is connected with a positive electrode lead of the output end of the battery pack through a pin 1 of the panel plug, an outgoing line 2 of the water pressure switch is connected with a Hall switch lead 1, and a lead 2 of the Hall switch is connected with a positive electrode of a power supply of the signal processing board through a pin 2 of the panel plug; the negative lead of the battery pack is connected with the negative electrode of the power supply of the signal processing board; the outgoing line of the triaxial acceleration sensor is connected with the signal processing board.

Furthermore, an acceleration signal of the speed measuring and recording device is recovered, and a speed result of the platform submarine emission pipe is obtained through calculation.

Further, the sampling rate for acquiring the accelerometer signal is 1 kHz.

Has the advantages that:

when the water pressure switch or the Hall switch is in an off state, the speed measuring and recording device is in an off state, so that the system is in a low power consumption state. When the water pressure switch and the Hall switch are in the on state at the same time, the speed measuring and recording device starts to work, and the real-time speed of the whole process of the platform discharging pipe can be obtained through subsequent calculation. And the average speed of the platform in the pipe outlet process can only be obtained by adopting the conventional measuring means of the infrared technology.
