具体而言，WiFi定位功能模块用于获取待定位资产周围的WiFi接入点信息，即保存接入点AP的MAC地址信息，如当前MAC地址信息在资产管理服务器设置的相应区间列表内，则可判断其位置在相应的区间内，从而确定待定位资产的位置信息。而如果多个MAC地址均不在相应区间列表内，即待定位资产搬动到其他地方，则需执行循环定位上报给资产管理服务器以获取当前的待定位资产位置信息。Specifically, the WiFi positioning function module is used to obtain the WiFi access point information around the asset to be located, that is, to save the MAC address information of the access point AP. If the current MAC address information is in the corresponding interval list set by the asset management server, then It can be judged that its position is within the corresponding interval, so as to determine the position information of the asset to be located. However, if multiple MAC addresses are not in the corresponding range list, that is, the asset to be located is moved to other places, it is necessary to perform cyclic positioning and report to the asset management server to obtain the current location information of the asset to be located.
