Mehtod for length measuring by mobile communication terminal

Abstract

The present invention discloses a mehtod for length measuring by mobile communication terminal, which is used for a built-in short distance communication equipment in the mobile communication terminal; which transmits a certain signal to a reflecting surface, and then grasps the characteristicof surface reflection according to the weakening extent of the received signal, and then measures the distance between the reflecting surface the mobile communication terminal. The present invention uses the short distance communication equipments which has been set up in the mobile communication terminals, using the weakening of signal strength generated by the transmitted reflection signals by the said communication equipments to measure the distance between the reflective object and the mobile communication terminal. Taking into account the reflective properties of the reflective object, the present invention takes the external structures of the mobile communication terminals from a fixed distence as a reference, to analyse the reflective properties of the specific reflective object, and takes it as the basic information of its length measurement. Therefore, regardless of whatever types of the reflective objects, regardless of the time and places, the present invention can achieve a more precise length measurement, accordingly achieving the effect of providing convenience for users.

Description

technical field [0001] The present invention relates to a length measurement method implemented by a mobile communication terminal, in particular, to a built-in short-distance communication device used in a mobile communication terminal. After sending a certain signal to a reflecting surface, it can be grasped according to the weakening degree of the received signal. Reflecting surface characteristics, and a method for measuring the distance between the reflecting surface and the mobile communication terminal by using the mobile communication terminal to measure the length. Background technique [0002] With the rapid popularization of mobile communication terminals, the performance of mobile communication terminals has also been further improved rapidly. The performance improvement of this mobile communication terminal reflects the new requirements of users in terms of changes in communication methods, production and playback of multimedia content, etc. In order to achieve ...

Problems solved by technology

However, the problem with this device is that it is not very suitable for measuring the length of an object containing a curved surface, such as measuring the height of a human body, etc., and because its driving part must be exposed to the outside, it is easy to be polluted and cannot be used. There is also a risk of damage to the work, and at the same time it increases the size of the mobile communication terminal and reduces its portability

[0007] In addition, when measuring the length of an object, although measuring tools such as a tape measure can also be used, since users cannot often carry these measuring tools, it is difficult to measure the length of the target object when necessary

[0008] As mentioned above, in the existing length measuring method using a mobile communication terminal, a special sensor capable of measuring the length of the communication terminal is added to the mobile communication terminal, or a method of a specially designed driving part. However, if the above-mentioned length measuring device is inserted into the mobile communication terminal, it will increase the size of the mobile communication terminal and reduce its portability. Moreover, since the measurement part is exposed to the outside, there is also the problem that it is easy to be polluted and damaged.
