and S101, receiving and storing a signal sent by a transmitter arranged on the children clothes, wherein the signal carries position information.
Specifically, the receiving end may be an intelligent device capable of receiving information, such as a mobile smart phone, a desktop computer, or a vehicle-mounted computer. The emitter can be arranged on a button of the children garment, the button is not close to the skin on the garment, and the emitter is in contact with the external environment and has a good signal emission environment. The positioning module is used for sending the positioned position information to a monitoring terminal, namely a receiving terminal, through the transmitter, and meanwhile, the monitoring terminal stores the position information received each time.
Step S102, under the condition that the signal of the transmitter is not received within a preset time period, the signal intensity of the signal received last time is obtained, and the first distance between the target child wearing the child clothes and the monitoring terminal when the signal is transmitted last time is determined according to the signal intensity.
The transmitter can be set to send the position information to the monitoring terminal once every preset time, and if the monitoring terminal does not receive the signal transmitted by the transmitter within the preset time, there may be a risk that the target position to be transmitted by the transmitter, that is, the target monitoring terminal, is tampered, or the position of the child exceeds the receiving range of the monitoring terminal, or the transmitter is damaged.
And if the monitoring terminal does not receive the signal transmitted by the transmitter within the preset time, acquiring the signal intensity of the signal received last time, wherein the signal intensity refers to the signal intensity between the transmitter and the monitoring terminal. Specifically, the signal strength of the signal received the last time is analyzed, the signal strength can indirectly reflect the distance between the signal transmitting position and the monitoring terminal, and if the signal strength is strong, the signal transmitting position is close to the monitoring terminal, otherwise, the signal strength is far.
Further, a reference distance between the target child wearing the child garment and the monitoring terminal when the transmitter transmits the signal for the last time is determined according to the strength of the signal received for the last time, and the reference distance is used as a first distance in the embodiment, where the range of the first distance may be a circumferential range with the monitoring terminal as an origin O and the first distance as a radius R, as shown in fig. 2.
Step S103, analyzing the first position information in the signal received last time, and acquiring the second position information of the monitoring terminal.
The received latest signal is analyzed, the position information included in the signal is obtained, that is, the position of the transmitter is used as the first position information, the position information is the specific position information transmitted by the annunciator, and the position of the monitoring terminal is obtained at the same time, and the position is used as the second position information in this embodiment.
Step S104, determining a second distance between the target child and the monitoring terminal based on the first position information and the second position information.
And calculating the actual distance between the target child and the monitoring terminal according to the first position information of the position of the emitter analyzed by the monitoring terminal and the second position information of the position of the monitoring terminal, and taking the actual distance as the second distance in the embodiment.
Step S105, if a difference between the first distance and the second distance is smaller than a preset threshold, determining that the first position information is valid information, so as to track the target child according to the first position information.
As shown in fig. 2, assuming that a position of a transmitter analyzed by the monitoring terminal is a point P, that is, a position of a target child is the point P, a distance between the point P and a point 0 is a first distance L, a difference between the first distance L and a second distance R is calculated, and whether the difference is smaller than a preset threshold is determined, if the difference is smaller than or equal to the preset threshold, the first position information is determined to be valid information, and the target child is tracked according to the first position information. If the difference value is larger than or equal to a preset threshold value, determining that the first position information is invalid information, selecting the signals received at the same time again, analyzing the first position information in the signals received at the same time, analyzing a first distance between a target child wearing the child garment and the monitoring terminal when the signals are transmitted at the last time, obtaining second position information of the monitoring terminal, determining a second distance between the target child and the monitoring terminal according to the first position information and the second position information again, judging whether the difference between the first distance and the second distance is smaller than the preset threshold value, if so, tracking the target child according to the first position information in the signals received at the same time and the first position information.
In this embodiment, when the target child wearing the child garment exceeds the signal receiving range of the monitoring terminal or the difference between the first distance and the second distance is greater than or equal to the preset threshold value, the child garment can also perform audible alarm prompt.
In the embodiment, firstly, the signal transmitted by the transmitter is received, the signal is analyzed to determine the specific position information of the target child wearing the child garment, the first distance between the specific position of the target child wearing the child garment and the monitoring terminal is obtained, secondly, determining a second distance between the target child wearing the child garment and the monitoring terminal by using the signal strength, and finally, judging the validity of the position information of the target child wearing the child garment carried in the received signal by calculating the difference value between the first distance and the second distance, therefore, whether the information received by the monitoring terminal is at risk of being tampered or not is identified, the position information of the target child wearing the child garment received by the monitoring terminal is ensured to be in accordance with the actual position, and the authenticity of the position information of the target child wearing the child garment received by the monitoring terminal is ensured.
