Embodiment 1

[0029] The switch box (called HRCSF) for the integrated test of the communication base station includes a box body, and the inner wall of the box body is provided with a shielding coating with a thickness of 2 microns; The splitter and the main board of the integrated automatic test control module belong to the existing circuit connection.

[0030] See attached figure 1The front of the box body 1 is equipped with a visual touch screen 2, a test instrument port 3, and a self-locking switch button 4, and there are rectangular cooling holes 5 distributed on the side and top of the box body; the internal mounting frame of the box body of the present invention adopts metal with screw holes The main keel is used to fix the main support and the panel, and the metal auxiliary keel with screw holes is used to fix and adjust the internal components. The specific installation method belongs to the conventional means of mechanical installation. See attached figure 2 , There are 8 upper...

Embodiment 2

[0036] The switch box for the integrated test of the communication base station, except that the power divider is replaced by a circulator, and the inner wall of the box is provided with a shielding coating with a thickness of 3 microns, the rest is the same as that of the first embodiment, and the NB- The IOT uplink signal indicator uses a circulator internally to introduce the steps of testing the hardware test switch box HRCSF. like Figure 4 As shown, the test unit includes 12 low intermodulation attenuators 11, 3 high-performance coaxial switches 12 and circulators 14 connected in sequence:

[0037] When the A port is selected through the visual touch screen, the signal source outputs any level of NB-IOT signal; the signal passes through the circulator, and then is transmitted to the low intermodulation attenuator through the two-stage high-performance RF coaxial switch for attenuation, after attenuation The signal is transmitted to the A port of the base station to be t...

Embodiment 3

[0039] The switch box for the integrated test of the communication base station is the same as the first embodiment except that 12 low intermodulation attenuators are increased to 16. The result of the switch box HRCSF test base station signal is accurate, and the error is less than 8 / 10,000.

Abstract

The invention discloses a switch box used for integration testing by a communication base station. The switch box comprises a box body, wherein low intermodulation attenuators, coaxial switches and a correction device are arranged in the box body and sequentially connected; the correction device comprises a power divider or a circulator; and shielding coatings are arranged on the inner side walls of the box body, and the thicknesses of the shielding coatings range between 2 microns and 3 microns. The switch box provided by the invention has the advantages that the structure is optimized; it can be seen that the requirements for high integration, high usability, high reliability, high automation and standardization are satisfied; and effective heat dissipation, high reliability and the like are achieved.

Description

technical field [0001] The invention relates to functional and performance index testing equipment for base stations, in particular to a switch box for integrated testing of communication base stations, which is used for efficient and reliable construction of automated integrated testing systems for FDD LTE and NB-IOT communication standard products. Background technique [0002] With the development of communication technology, in wireless communication, communication networks of various standards are constantly updated. In order to meet people's increasing demand for networks, the technology of the fourth-generation mobile communication system network is also constantly updated. Network communication quality and network coverage have become the main indicators of major operators' competition. [0003] At the same time, a new branch of the new generation of wireless communication technology has emerged on the basis of FFD LTE: the NB-IOT communication system for the Interne...
