Design method for full coverage of digital cluster type wireless intercom signals

Abstract

The invention discloses a design method for full coverage of digital cluster type wireless intercom signals. The design method comprises the following steps: determining the initial positions and thenumber of antennas according to the outline and the area of a target area; according to the intersection position of the maximum coverage radiuses of the two adjacent antennas and the penetration lossof the obstacle at which the antennas reach the intersection position, obtaining the indoor space field intensity at which the antennas reach the intersection position; comparing the indoor space field intensity with preset indoor space field intensity, and obtaining a comparison result; adjusting the initial position of the antenna according to the comparison result until the indoor space fieldintensity is smaller than the preset indoor space field intensity, and taking the adjusted position of the antenna as a target position; and if the contour of the target area is not covered by the signals of the antennas, increasing the number of the antennas, and determining the initial positions of the antennas again according to the contour and the area of the target area. The blind area formedby the shielding and absorbing effects of a building in a large complex is solved, and indoor full-area signal coverage is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of wireless intercom, in particular to a design method for full coverage of digital trunking wireless intercom signals. Background technique [0002] The role of information technology in people’s production and life has become increasingly prominent. As an important way of information exchange, wireless walkie-talkie coverage systems have become an indispensable part of the management department as a wireless mobile communication tool for daily operation scheduling and security assurance. , With the development of the enterprise, it is constantly improving and upgrading to a more efficient, more comprehensive and safer communication platform. [0003] The digital trunking wireless intercom signal coverage system is a new generation communication platform, which makes the system upgrade and expansion more flexible, the voice is clearer, the signal coverage inside the building is more evenly distributed, external si...

Problems solved by technology

[0004] In recent years, due to construction reasons, especially large-scale complex buildings, the building structure is complex, and the reinforced concrete structure is more shielded, especially some underground buildings. The internal structure of the building is complex, and the blocking and blocking are different in different directions of the antenna, which will cause signal coverage. blind spot
