Technical field

The present invention relates to the moving distance measuring devices and moving distance measuring method of the moving distance of measurement moving body. The invention further relates to the elevators and vehicle that have moving distance measuring device.

Background technique

For example, the moving distance measuring device is installed on Patent Document 1 discloses a kind of moving distance measuring device On the moving bodys such as carriage, the vehicle of elevator, the moving distance and/or speed of electric wave measurement moving body are used.

Patent document 1 discloses the following contents: electric wave is sent from moving body (vehicle) to stationary plane (ground), according to hair It send and orthogonal detection is carried out to back wave on the basis of wave and the variable quantity of calculated phase calculates moving distance.Due to not making Moving distance is calculated with the amplitude information of back wave but according to the variable quantity of phase, therefore, even if in the electric wave of stationary plane Reflective condition sharply change in the case where, also can accurately measure moving distance.

Summary of the invention

Subject to be solved by the invention

According to patent document 1, electricity is sent to the stationary plane that there are the ground of railway ballast and sleeper, i.e. there are random bumps Wave calculates moving distance using the variable quantity of the phase of its back wave and reflected intensity are maximum angle.However, in fixation In the case that the surface in face is not equably flat, reflected intensity is that maximum angle changes along with mobile, accordingly, there exist The calculated result of moving distance generates the project of error.Further, since reflected intensity be maximum angle be using from antenna to What the distance of stationary plane was calculated, therefore, the project of error is generated there is also the installation deviation due to antenna.

It is an object of the present invention to solve the above subject, moving body can accurately be measured compared with prior art by providing Moving distance moving distance measuring device and moving distance measuring method.The object of the invention is also to provide have to move Dynamic elevator and vehicle apart from measuring device.
