The invention discloses a digital measurement ruler and a measurement method thereof. The measurement ruler comprises a soft ruler belt, a first photoelectric sensor, a second photoelectric sensor, a detection circuit, a connecting disc, an outer shell, a Bluetooth control chip, a display screen, an LED data transmission indicator lamp, a function switch, a power supply module and a client side; the Bluetooth control chip acquires the displacement length of the soft ruler belt according to a received signal of the photoelectric sensor and controls the display screen to display data in real time. The reflective photoelectric sensor is used to detect the displacement, then the measurement accuracy is guaranteed, the design cost is also lowered; the chip resource is fully utilized, the unnecessary cost waste is avoided; the measurement data are displayed in real time, the phenomenon of rework, caused by the measurement error of the faulted measurement ruler, is avoided; the data are not artificially recorded and summarized, the working efficiency is improved, the manpower cost is lowered, and meanwhile, the centralized management and use of the data is facilitated.
Description
Technical field [0001] The invention belongs to the technical field of intelligent measurement, and specifically relates to a digital measuring ruler and a measuring method thereof, which is applied to human body measurement in the clothing customization industry. Background technique [0002] The existing digital tape measure technology has matured, and the digital display tape measures on the market have the functions of LCD display, data metric and inch conversion, and memory of a little data. However, it involves a large amount of data to be tested in specific industries (clothing customization, home design, wood industry, etc.). Although digital tape measures on the market are convenient to read, they are still relatively inefficient in actual operation. Each measurement needs to be manually filled on paper. Table records, and then entered into the computer table. Especially in the field of clothing customization, a sizingist faces about 60 to 80 customers a day. At most, i...
