Measurement instrument used for ABS (anti-lock brake system) sensor

Abstract

The invention provides a measurement instrument used for an ABS (anti-lock brake system) sensor. The measurement instrument is characterized in that an electronic control cabinet is provided with a control box; an LCD (liquid crystal display), an operation panel and an acousto-optic prompting system are configured on the control box; a main board of the electric control cabinet is provided with an CPU (central processing unit) provided with A / D (analog to digital) converter; a D / A (digital to analog) converter, an LCD operating display module, an extended memory, an ABS signal interface, a power supply circuit, an RS232 / 485 (recommend standard 232 / 485) interface and an optical isolation I / O (input / output) interface are connected with the CPU provided with the A / D converter; the RS232 / 485 interface is connected with a host computer system; the optical isolation I / O interface is connected with the operation panel module; and the optical isolation I / O interface, the D / A converter and the power supply circuit are connected with a servo drive interface. The measurement instrument provided by the invention has the beneficial effects of having an operation function, a display function, a comparison memory function and an acousto-optic prompt function and being high in measurement accuracy, simple and convenient in operation, lower in production cost and wide in application range.

Description

technical field [0001] The invention relates to the field of measuring instruments, in particular to a measuring instrument used for ABS sensors. Background technique [0002] At present, there are two main measurement methods for commonly used ABS sensors: 1. Use special instruments for measurement, but the price is expensive; 2. Use instruments such as oscilloscope multimeters to see the output voltage graph but cannot realize numerical calculations and cannot use sound. , The light mode prompts the operator, and the operator's experience needs to be judged during the measurement, which is prone to misjudgment and labor-intensive. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to provide a measuring instrument for ABS sensors with high measurement accuracy, easy operation, low production cost and wide application range. [0004] In order to achieve the above object, the technical solution adopted in the...
