Kind Code:
A1
Abstract:
An old person anti-lost device based on NB-IOT narrowband Internet of Things technology, comprising a locator (1), a host end (2), and an auxiliary end (3). The front surface of the locator (1) is fixedly connected to an indicating lamp (4), a signal transceiving port (5), and a press key (6) from top to bottom in sequence. The device may monitor the distance of an old person from home by means of cooperation of a fixed-point position editing module (291) and a distance determining module (292), and performs reminding by means of a timing reminding module (294) after the old person is away from home a certain distance, and the device may send a wireless signal to the auxiliary terminal (3) of a family member. A day and night identification module (293) may analyze the time; when the old person has not returned home at night, the family member is reminded no matter how far away the old person is from home; the family member can be reminded once in a while by editing a timing time by means of a timing editing module (295), thereby effectively avoiding the situation that the old person is lost; and the NB-IOT narrowband Internet of Things technology is utilized, so that the power consumption of the device is low, and the endurance ability is high.
