Low power sonar altimeter

Abstract

The invention discloses a low power sonar altimeter. A control power control module receives externally input power supply signal and power supply control signal and supplies power to a 232 communication module and an MSP430 single chip microcomputer. The 232 communication module communicates with the outside and the single chip microcomputer, receives an external control instruction, and sends the external control instruction to the single chip microcomputer so as to control the single chip microcomputer to carry out switch-on and switch-off control and signal emission, reception and processing. The 232 communication module receives a switch control signal emitted by the single chip microcomputer, and switch-on and switch-off are realized under the control of the switch control signal. An MSP 430 single chip microcomputer generates an emission pulse signal and sends the emission pulse signal to an emitting module, receives an echo signal, processes the echo signal to obtain a height result, and outputs the result through the 232 communication module. The single chip microcomputer sends switch control signals to the 232 communication module and a switch circuit so as to control the switch-on and switch-off of the 232 communication module and the switch circuit. The switch circuit receives the input of an external power supply, and the power supply output end is connected to the emitting module and a receiving module to control the switch-on and switch-off of the power supplies of the emitting module and the receiving module. A transmitting and receiving combined transducer carries out transmitting and receiving transduction processing.

Description

technical field [0001] The invention relates to sonar technology, in particular to a low power consumption sonar altimeter. Background technique [0002] Sonar altimeters are used in various underwater vehicles such as UUVs, underwater gliders, and submarines to measure the height of the aircraft to the seabed and provide a basis for collision avoidance and route decision-making. Existing products at present, such as the PSA-916 sonar altimeter of American Benthos Company, have the problem of high standby power consumption. It is difficult to meet the requirements of underwater work. Contents of the invention [0003] In view of this, the present invention provides a low-power sonar altimeter, which can realize a standby state, a power-off state or a working state according to its use requirements, thereby reducing power consumption. [0004] The technical solution of the present invention is: a low-power sonar altimeter, including a control power supply module, a 232 co...
