Problems solved by technology

[0002] At present, the safety light curtains on the market have a long scanning cycle due to the scanning method. For example, the traditional beam scanning method scans one by one from the beginning to the end. This method has a long scanning cycle and the reaction speed of the product is greatly restricted.

Embodiment Construction

[0013] Such as Figure 1 ~ Figure 2 As shown, a scanning method of a safety light curtain includes a light projector and a number of light-emitting emitting tubes, a light receiver and a number of light-receiving tubes, and output processing:

[0014] Step 1: Scan in segments. Several light emitting tubes at the projector end are divided into multiple segments for independent scanning, and the light receiver at the receiver end receives a corresponding number of segment scans;

[0015] Step 2: Signal summarization, each segmented light-receiving unit at the receiver end carries out independent pre-processing of the signals and then merges them to the first segment scanning unit;

[0016] The total number of M transmitting tubes or receiving tubes is divided into n sections of independent scanning units, and the number of transmitting tubes or receiving tubes of the n sections of independent scanning units is the same or different or partly the same.

[0017] After the signal processin...

Abstract

The invention provides a scanning method of a safety light curtain. In the method, a light projector, a plurality of light projection transmitting tubes, a light receptor and a plurality of light receiving tubes are comprised, and the method comprises the steps of 1, segmented scanning, namely dividing the plurality of light projection transmitting tubes at the light projector end into a pluralityof segments to perform independent scanning, and enabling the light receiving tubes at the light receptor end to perform the corresponding number of segmented scanning; 2, signal collection, namely independently preprocessing the signals by each segmented light receiving unit at the light receiver end and then combining and collecting the signals to a first segment of scanning unit; dividing thetransmitting tubes or the receiving tubes with the total number M into n sections of independent scanning units, wherein the transmitting tubes or the receiving tubes of the n sections of independentscanning units are the same or different or partially the same in number. The n sections of independent scanning units at the light receptor end are all connected in parallel and gathered to the firstsection of scanning unit for output preprocessing after signal processing. According to the method, a sectional scanning and summarizing processing mode is adopted, the scanning period is short, thereaction action of a product is fast, and the scanning efficiency is greatly improved.

Description

Technical field [0001] The invention relates to a safety light curtain, in particular to a scanning method of the safety light curtain. Background technique [0002] At present, safety light curtains on the market have a long scanning period due to the scanning method. For example, the traditional beam scanning method scans one by one from beginning to end. This method has a long scanning period and the response speed of the product is greatly restricted. Summary of the invention [0003] Aiming at the shortcomings of the existing technology, the present invention provides a scanning method for a safety light curtain. [0004] In order to achieve the above objectives, the technical solution adopted by the present invention is: a scanning method for a safety light curtain, including a light projector and a number of light projection emitting tubes, a light receiver and a number of light receiving tubes, and output processing: [0005] Step 1: Scan in segments. Several light emitting t...
