Abstract

The invention discloses a liquid level detection device and method. The liquid level detection device comprises light emitting equipment (11), multiple light guiding fibers (12), a detection tool (13) and a shell (14); the light emitting equipment (11) is provided with multiple light sources (111), and each light source generates a directional light beam (112); one end of each light guiding fiber corresponds to and receives a light beam signal generated by the corresponding light source (111), and the other end of each light guiding fiber transmits out the light beam signal for observation; the detection tool (13) is arranged in liquid to be detected and positioned to be capable of shielding at least part of the light beams, and then the light guiding fibers cannot receive the corresponding light beam signals; the light emitting equipment (11) and the receiving ends of the light guiding fibers (12) are arranged on the shell (14).

Description

technical field [0001] The invention relates to a liquid level detection device and method, in particular to a liquid level detection device and method for vehicle gearboxes. Background technique [0002] At present, there are mainly two methods for detecting the liquid level of the automobile gearbox: using the oil drain method for detection and using the oil dipstick attached to the vehicle for detection. Among them, the oil drain method is to remove the blockage of the detection port preset at a specific height of the gearbox, and observe whether there is oil flowing out, so as to obtain the liquid level information. To test with the oil dipstick attached to the vehicle, insert the oil dipstick into the corresponding hole of the gearbox for liquid level detection, dip the oil, and then pull out the oil dipstick to observe the position of the oil on the dipstick, so as to obtain the liquid level information . [0003] The above two methods have their own disadvantages. ...
