Description

Perception threshold determining method and device and electronic equipment Technical Field The present application relates to network communication technologies, and in particular, to a method and an apparatus for determining a perception threshold, and an electronic device. Background Currently, sensing tasks such as gesture control, fall detection, tracking, imaging, activity recognition, vital sign monitoring, etc., are often performed using sensing thresholds. For example, a sensing algorithm is utilized to perform sensing operation on the sampling data to obtain an operation result, and the sensing tasks such as gesture control, fall detection and the like are realized by comparing the operation result with a sensing threshold value. Taking a falling detection sensing task as an example, if the operation result is greater than or equal to a sensing threshold, determining that a falling occurs, otherwise, if the operation result is less than the sensing threshold, determining that no falling occurs. The sensing algorithm is, for example, an algorithm simulating the working principle of human nerve cells, and the main purpose of the sensing algorithm is to learn a judgment rule from data so as to classify different situations. A conventional method of determining the perception threshold is to define that all receivers in the network use the same time window to determine the perception threshold. The receiver is used for sampling the sensing data sent by the transmitter, for example, the receiver may be all Access Points (APs) in the WLAN, and the transmitter may be a terminal (Station), and correspondingly, the sensing threshold is a WiFi sensing threshold. If all receivers in the network use the same time window to determine the perception threshold, for example, all APs in the WLAN use the same time window to determine the perception threshold, then the problem arises that for a certain receiver, for example, an AP, if the time window used for determining the perception threshold is too small, the perception threshold cannot be accurately determined, even the perception threshold determination fails, and if the time window used for determining the perception threshold is too large, the perception threshold cannot be quickly applied to an actual perception service, and the time window must be waited until the end of the above time window, so that an actual perception service delay is caused. Disclosure of Invention The embodiment of the application provides a method and a device for determining a perception threshold and electronic equipment, which are used for adaptively and dynamically determining a time window corresponding to each receiver for determining the perception threshold in the initialization process of a perception server, so that the defects caused by the fact that each receiver is fixed under the same time window for determining the perception threshold are avoided. The embodiment of the application provides a perception threshold determining method, which is applied to a perception server and comprises the following steps: receiving a perception service initialization request message from a perception application terminal; if the initialization is determined to be executed based on the sensing service initialization request message, determining a sensing threshold determination time window corresponding to each target receiver according to a target data sampling frequency F_sample and a target data reporting frequency F_report of each target receiver which are connected currently, wherein the target data reporting frequency F_report of the target receiver refers to the frequency of reporting a sensing result corresponding to the target receiver to the sensing application terminal by the sensing server; And determining the perception threshold value of the target receiver under different perception algorithms based on the data sampled by the target receiver in a perception threshold value determination time window corresponding to the target receiver. The embodiment of the application also provides a device for determining the perception threshold, which is applied to the perception server and comprises the following steps: the system comprises a sensing server, a time window determining unit, a sensing application end and a target server, wherein the sensing server is used for receiving a sensing service initialization request message from the sensing application end, and determining a sensing threshold determining time window corresponding to each target receiver according to a target data sampling frequency F_sample and a target data reporting frequency F_report of each target receiver if the initialization is determined to be executed based on the sensing service initialization request message, wherein the target data reporting frequency F_report of each target receiver refers to the frequency of reporting a sensing result corresponding to the target receiver to the sensing applica
