Embodiment 1

[0067] refer to Figure 5-12 , in order to realize the fixation of the display and the adjustment of its height and tilt angle in space to meet the needs of users, in this embodiment, the display stand includes a mounting plate 100, an adjustment module 200, a support module 300 and a display Body 500. Specifically, the mounting plate 100 is arranged on the top of the bracket and is used for the installation of the display body 500, the adjustment module 200 connected to the rear side of the mounting plate 100 and capable of adjusting the position and posture of the mounting plate 100 in space, and used to support and install the entire bracket. and the adjustment module 200 also includes an upper adjustment assembly 201, an adjustment assembly 202, and a shaft arm 203; wherein the upper adjustment assembly 201 and the lower adjustment assembly 202 are respectively arranged at the upper and lower ends of the shaft arm 203, and the upper adjustment assembly 201 The lower adjus...

Embodiment 2

[0081] In the above-mentioned first embodiment, relative rotation can occur between the shaft seat 103 and the shaft pin 104, and the horizontal shaft block 201a is inserted into the shaft pin 104 to limit and fix, and there will be no relative rotation between the two, so the installation The disk 100 can rotate around the horizontal axis block 201a, but if the weight of the display screen on the installation disk 100 is too large, and with the increase of the number of rotations between the shaft pin 104 and the shaft seat 103, the contact surface will gradually change after continuous wear. It is smooth and the friction force gradually decreases, so the mounting plate 100 cannot be fixed at the designated position during use, and a slight vibration will cause the mounting plate 100 to slide down, so the difference between this embodiment and the first embodiment That is: a magnetic lock module 400 is also provided between the shaft pin 104 and the shaft seat 103, which can l...

Abstract

The invention discloses a location selection method and device from a port logistics area to the hinterland, comprising: calculating the transportation cost coefficient from each candidate point to the direct hinterland; calculating the transportation cost coefficient between each candidate point and the indirect hinterland; introducing the first weight and the second weight , to calculate the comprehensive transportation cost coefficient from the candidate point to the hinterland. The present invention is divided into indirect and direct calculations, and finally obtains a site selection method from the comprehensive port logistics area to the hinterland, and provides a site selection device based on the organization coefficient of the logistics supply chain, which can stabilize the display or display screen The free adjustment of tilt angle and direction in the space avoids sliding caused by shaking or excessive use, and it is very simple and quick.

Description

technical field [0001] The invention relates to engineering site selection, in particular to a method and device for site selection from the port logistics area to the hinterland. Background technique [0002] The 3D GIS data model can be divided into surface model and volume model. The surface model data structure focuses on the representation of three-dimensional space surfaces, such as terrain surfaces, geological layers, etc., including grid structure (grid), irregular triangulated network (TIN), boundary representation and parameter functions, etc. In practical applications, there are many ways of grid structure and irregular triangular network. The advantage of forming three-dimensional object representation through surface representation is that it is convenient for display and data update, but it is two-dimensional in nature, and can only obtain the information of the surface, and cannot effectively represent any point inside the surface. Because of the visual effe...
