Embodiment Construction
[0051] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0052] Such as figure 1 Shown, a kind of data processing method of ranging sensor, comprises the following steps:
[0053] S1. During the movement of equipment A, the ranging sensor installed on equipment A continuously measures the distance between equipment A and equipment B according to the specified time interval T, and obtains the original distance measurement data A 1 、A 2 、A 3 ,...A n and ranging timestamp t 1 , t 2 , t 3 、......t n ; where A i for timestamp t i Corresponding ranging raw data, i=1,2,3,...,n;
[0054] S2. Select 3 ranging raw data A n-3 、A n-2 、A n-1 as a data sample;
[0055] S3. Judging the validity of the data sample:
[0056] S301. Determine whether the time interval between any two adjacent data sa...

The invention discloses a data processing method of a distance measuring sensor, which comprises the following steps that: S1: in the movement process of equipment A, a distance measuring sensor arranged on the equipment A continuously measures the distance between the equipment A and equipment B according to a specified time interval to obtain distance measurement original data A1, A2, A3,... Anand distance measurement timestamps t1, t2, t3,... tn, wherein Ai is distance measurement original data corresponding to the time stamp ti, and i is equal to 1, 2, 3,..., n; S2, three pieces of distance measurement original data A<n-3>, A<n-2> and A<n-1> are selected as data samples; S3, the validity of the data samples is judged; and S4, the state of the equipment A is judged according to the valid sample data. According to the method, the abnormal change data can be effectively eliminated, accurate sample data can be obtained, and an accurate basis is provided for judging the motion state and obtaining the distance measurement information and the speed information.
Description
technical field [0001] The invention relates to equipment distance measurement, in particular to a data processing method of a distance measurement sensor. Background technique [0002] Subway engineering vehicles are generally not equipped with train control equipment, and the operation process is completely dependent on the driver's experience control, resulting in frequent problems such as overspeeding, rushing, and jamming when operating engineering vehicles. Effective supervision measures lead to greater safety risks in engineering vehicle operations. [0003] Using the ranging sensor to measure the distance between the device and the surrounding target equipment is of great significance to reduce the driving risk. However, the data detected by the ranging sensor may change due to the environment, the device itself and various emergencies. Thereby causing interference to normal information.
