Problems solved by technology

Since there is no external power supply on the axis, the Bluetooth transmitter usually has a built-in battery, which needs to be replaced frequently. At the same time, there are certain limitations in the accuracy and transmission distance of the Bluetooth signal, which usually results in signal loss. In this case, it is difficult to guarantee the accuracy of the measurement results. precision

Abstract

The invention relates to the technical field of measuring equipment, and discloses a shaft rotating speed measuring device which comprises a measuring instrument and a baffle ring annularly arranged on a rotating shaft, a laser via hole is formed in the baffle ring, and the measuring instrument comprises a laser transmitter, a laser receiver, a mounting frame, a connecting frame and a main controller. The laser emitter and the laser receiver are both installed on the installation frame, the laser emitter is right opposite to the laser receiver, a baffle ring passage is formed between the laseremitter and the laser receiver, laser beams emitted by the laser emitter are perpendicular to the speed measurement direction, the installation frame is installed on the connection frame, the connecting frame is fixedly arranged, and the laser emitter and the laser receiver are electrically connected with the main controller; according to the invention, high rotating speed measurement precision and stable transmission performance can be achieved.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a shaft speed measuring device. Background technique [0002] Since the main engine of the ship does not have an independent power monitoring system, its power monitoring relies on the external speed sensor on the shaft to transmit the speed signal, and the power of the main engine is obtained after conversion through the built-in program of the main engine. When the rotational speed sensor on the shaft fails, it will cause the main engine Wrong power. [0003] At present, the speed sensor on the ship measures the speed in the following way: the inner ring is a Bluetooth transmitter, which is fixed on the shaft, and the outer shell is a Bluetooth receiver fixed in one place. When the bearing rotates, the Bluetooth transmitter follows the bearing and turns to the Bluetooth receiver. When it is in the position of the controller, it sends a Bluetooth signal, and the Blu...
