Description

Test method, device, equipment and system Technical Field The present application relates to the field of wireless technologies, and in particular, to a testing method, apparatus, device, and system. Background With the development of the sense-of-general-sense integrated technology, the sense-of-general-sense integrated base station supporting scenes such as low-altitude unmanned aerial vehicles, ground vehicle pedestrians, water area ships and the like is provided at present. The perceived minimum received power, i.e., the received sensitivity of the perceived signal, refers to the ability of the integrated system to detect and process weak signals from the perceived target, typically used to describe the performance of the integrated system. The magnitude of the perceived minimum receiving power depends on factors such as noise level of the sense-all-in-one receiving system, gain of an amplifier, signal processing efficiency and the like, is an important performance index in the design of the sense-all-in-one system, and plays a very important role in application scenes requiring high-precision and long-distance detection. In the related art, as shown in fig. 1, a scheme of performing a sensing minimum received power test on a sense integrated base station is that a set of standard uplink reference measurement signals are generated by using a vector signal source and transmitted to a receiver, where an attenuator may be set on a transmission channel, and then an output power value of the vector signal source is adjusted and adjusted based on a statistical result of a throughput statistical tool or a bit error rate statistical tool of a base station maintenance station, so as to determine a reference value of a receiving sensitivity, that is, a test result of a sensing minimum received power. Illustratively, the base station maintenance station receives at least 10000 sub-frame data to calculate throughput, and finally adjusts the output power value of the vector signal source so that the statistical value of the throughput is slightly greater than 95%, and records the output power value of the vector signal source at this time as the reference value of the receiving sensitivity. And testing the minimum perceived power, wherein the testing requirement is that when the perceived target randomly appears in the coverage area of the base station and the echo power of the perceived target is greater than or equal to the corresponding equipment index requirement of the base station, the base station can identify the position and the speed of the perceived target under the required detection rate, and the position precision and the speed precision meet the technical index requirement. However, in the related art, the test signal used in the communication sensitivity test scheme of the base station does not have the characteristics of the double-blind discrete model, and cannot simulate the position, the speed and other information of a random target in the coverage area of the base station, further, the test instrument generating the signal source cannot generate an echo signal matched with the characteristics of the double-blind discrete model so as to simulate the echo of the real perceived target, and further, the accuracy of the detection rate, the position precision and the speed precision cannot be judged when the test result is judged, so that the test requirement of the base station on the perceived minimum received power cannot be met.

The technical scheme of the application is realized as follows: the application provides a testing method which is applied to first equipment, and comprises the following steps: determining first information, wherein the first information characterizes the speed range, the distance range and the position of a plurality of simulated perception targets, and the plurality of perception targets are distributed on a plurality of random positions in the coverage range of a base station; Generating second information, wherein the second information comprises a plurality of groups of signal parameters, each group of signal parameters in the plurality of groups of signal parameters are respectively used for simulating echo signals of sensing signals sent by the plurality of sensing targets to a base station, and the receiving power of the base station to the plurality of echo signals is the same; And determining the detection rate of the base station based on the first information and third information, wherein the third information characterizes the perception information of the plurality of perception targets analyzed by the base station through receiving a plurality of echo signals, the plurality of echo signals are correspondingly transmitted by second equipment based on each group of signal parameters in t
