Embodiment one

According to an embodiment of the present invention, an embodiment of a method for determining the position of a target object is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

Fig. 1 is a flowchart of a method for determining the position of a target object according to Embodiment 1 of the present invention. As shown in Fig. 1, the method includes the following steps:

In step S102, the monitoring terminal collects identification information of target objects entering the monitoring range.

Specifically, the identification information may have a one-to-one correspondence with the target object, and may be a unique identification of the target object. When there are multiple target objects, the identification information can be used to distinguish different target objects. Wherein, the identification information may be the MAC address of the target object. Wherein, the monitoring range may be set within the wireless signal detection range of the monitoring terminal, or around a preset area (for example, a business place).

In a preferred solution of the present application, the monitoring terminal is any one or more of the following devices: wifi detection device, RFID device, NFC device, and wireless communication device based on 433/866 protocol.

In step S104, the monitoring terminal detects status information of the target object, wherein the status information includes at least signal strength and signal dwell time.

Specifically, when the state information includes signal strength, the monitoring terminal may detect the signal strength of the target object, for example, the signal strength is 50. When the status information includes the dwell time of the signal, the monitoring terminal may detect the dwell time of the target object, for example, the dwell time is 30 seconds.

Step S106, when the status information satisfies the preset condition, it is determined that the target object with the identification information is located in the specific area.

Specifically, the preset condition may be a preset analysis rule. When the state information includes signal strength and signal dwell time, the preset condition may be that the signal strength is greater than 50, and the signal dwell time is greater than 30 seconds.

It should be noted here that the corresponding relationship between the target object and the state information can be established through the identification information, and whether the position of the target object is located in a specific area can be determined through the analysis result of the state information. When the state information of the target object satisfies the preset condition, it can be determined that the target object is located within the specific area; when the state information of the target object does not meet the preset condition, it can be determined that the target object is located outside the specific area.

What needs to be explained here is that the analysis process of whether the execution state information satisfies the preset conditions can be performed by a monitoring terminal with storage and analysis functions, or can be completed by an analysis module independent of the monitoring terminal. Wherein, the analysis module can be located locally or in the cloud.

In the embodiment of the present invention, through the above steps S102 to S106: the monitoring terminal collects the identification information of the target object entering the monitoring range; the monitoring terminal detects the state information of the target object, wherein the state information includes at least signal strength and signal dwell time; When the status information satisfies the preset condition, it is determined that the target object with identification information is located in the specific area. The technical problem that it is impossible to determine whether the target object enters the designated area in the prior art is solved.

In an optional solution of the present application, in step S104, the method for the monitoring terminal to detect the state information of the target object may also include:

Step S1031, when the target object enters the monitoring range, the monitoring terminal records the current time as the first moment.

Specifically, the monitoring terminal records the time when the target object enters the monitoring range, for example, it may be 15:30:10, and 15:30:10 is recorded as the first moment.

Step S1032, when the target object leaves the monitoring range, the monitoring terminal records the current time as the second moment.

Specifically, the monitoring terminal records the time when the target object leaves the monitoring range, for example, it may be 15:31:15, and 15:31:15 is recorded as the second moment.

Step S1033, calculate the signal residence time of the target object through the first time and the second time.

Specifically, through the first moment: 15:30:10 seconds and the second moment: 15:31:15 seconds, it can be calculated that the signal residence time of the target object is 1 minute and 5 seconds.

The above step S1031 to step S1033 can realize how to detect the residence time of the target object in a specific area.

In an optional solution of the present application, in step S102, the monitoring terminal collects the identification information of the target object entering the monitoring range, including:

Step S1021, when any target object enters the monitoring range, trigger the monitoring terminal to collect the identification information of the target object entering the monitoring range;

Specifically, when there are multiple target objects, when any target object enters the monitoring range, the monitoring terminal collects the identification information of the target object.

Step S1022, saving the identification information of the target objects entering the monitoring range, and obtaining the number of target objects entering the monitoring range.

Specifically, the identification information of the target object can be stored in the monitoring terminal, or can be stored in the analysis module, and the analysis module can be located locally or in the cloud. The step of obtaining the number of target objects entering the monitoring range may be to add 1 to the current number of target objects when saving the identification information, and accumulate the numbers of multiple target objects.

What needs to be explained here is that when the target object is a customer of a business place, the flow of people around the business place can be calculated through the above steps S1021 and S1022.

In an optional solution of the present application, the identification information of the target object is obtained by detecting a wireless signal sent by the target object by the monitoring terminal.

Specifically, the wireless signal may be sent by the wireless communication device of the target object, and the monitoring terminal detects the identification information of the target object through the wireless signal.

What needs to be explained here is that when the target object is a customer of a business place, the monitoring terminal can detect the MAC address and signal strength of the customer's wireless communication device through the Wifi probe, wherein the customer's wireless communication device can be a mobile phone, terminal devices such as tablets. The analysis module in the cloud can be used to analyze parameters such as the signal strength of the customer's wireless communication device and the duration of the stay, so as to determine whether the customer has entered the business site or passed the business site.

In an optional solution of the present application, when the state information satisfies the preset condition, where, in step S106, after determining that the target object with identification information is located in a specific area, the method may further include:

Step S1071, recording the identification information of the target objects satisfying the preset condition, and obtaining the number of target objects satisfying the preset condition.

Specifically, the identification information of the target object meeting the preset condition can be stored in the monitoring terminal, or can be stored in the analysis module, and the analysis module can be located locally or in the cloud. The step of obtaining the number of target objects that meet the preset conditions may be to add 1 to the number of target objects that currently meet the preset conditions when saving the identification information that meets the preset conditions, and accumulate multiple target objects that meet the preset conditions quantity.

It should be noted here that when the target object is a customer of a business place, the flow of people entering the business place can be calculated through the above step S1071.

Step S1072, by recording the number of target objects meeting the preset conditions and the number of target objects entering the monitoring range, the percentage of target objects entering the specific area is calculated.

Specifically, the number of target objects that have been recorded to meet the preset conditions can be compared with the number of target objects that have entered the monitoring range to obtain the percentage of target objects that have entered a specific area, for example: when the number of target objects that meet the preset conditions is 85. When the number of target objects entering the monitoring range is 100, it can be calculated that the percentage of target objects entering the specific area is 85%.

In an optional embodiment provided by the present application, before the monitoring terminal collects the identification information of the target object entering the monitoring range, the method may also preset the signal strength range value of the monitoring terminal.

Wherein, when the state information satisfies the preset condition, the step of determining that the target object with identification information is located in the specific area includes: when the signal strength of the target object entering the monitoring range of the monitoring terminal is within the range of the first signal strength value , to determine that the target object is within a specific area.

After it is determined that the target signal is located in a specific area, further statistics on the attributes of the target object currently entering the specific area can be realized. In an optional solution, the residence time of the target object in the specific area can be further detected at this time. Wherein, the residence time is determined by the signal residence time of the target object; when the residence time of the target object in a specific area exceeds a predetermined time threshold, the passenger flow value in the specific area is accumulated.

Specifically, the above solution can be described in detail through the following specific application scenarios.

Taking a certain supermarket as an example, the embodiment of the scheme is described in detail. Assume that a monitoring terminal is set up in the supermarket, for example, a digital hard disk video recorder with a wifi probe function is set up. The wifi probe monitoring range covers the business area of the supermarket. The monitoring range of the wifi probe has a corresponding relationship with the business area of the supermarket. Specifically, the business area of the supermarket is divided into a tobacco and alcohol sales area, a fruit and vegetable sales area, and so on. The tobacco and alcohol sales area is in the A1 area of the supermarket business area, and the A1 area corresponds to the first area of the monitoring range of the wifi probe, which corresponds to a signal strength of 30-45; the fruit and vegetable sales area is in the C2 area of the supermarket business area, and Area C2 corresponds to the fifth area within the monitoring range of the wifi probe, and this area corresponds to a signal strength of 60-70.

When a customer carrying a mobile terminal enters the supermarket and the wifi probe perceives that the signal strength of the mobile terminal is between 30-45, it can be determined that the mobile terminal is in the first area of the monitoring range of the wifi probe, corresponding to the supermarket Area A1 is the area where tobacco and alcohol are sold. At the same time, calculate the time period during which the signal strength of the mobile terminal remains between 30-45, for example, the time period is 15:30:10 to 15:31:15, which is 1 minute and 5 seconds. It can be concluded that if a customer stays in the tobacco and alcohol sales area of the supermarket for 1 minute and 5 seconds, the traffic statistics of the tobacco and alcohol sales area will increase by 1. Similarly, when the wifi probe detects that the signal strength of a mobile terminal is between 60-70, it can be judged that the mobile terminal is in the fifth area of the wifi probe monitoring range, that is, the C2 area of the supermarket business area, that is, fruits and vegetables sales area, and calculate the duration of the mobile terminal signal at 60-70 at the same time, if it is from 16:00:00 to 16:02:10, it can be concluded that the customer stays in the fruit and vegetable sales area for 2 minutes and 10 seconds, then will The traffic statistics of the fruit and vegetable sales area increased by 1 place. In the above-mentioned passenger flow statistics of the supermarket, whether the customer is counted as effective passenger flow can be judged according to the preset duration, for example, the duration of the mobile terminal in the corresponding signal strength area can be preset to reach 30 seconds. If the duration in the area corresponding to the signal strength reaches 30 seconds, the customer is counted as valid passenger flow.

Through the embodiment provided by the present invention, it is possible to reasonably and effectively count passenger flow, provide accurate passenger flow data for merchants, optimize the purchase, display and sales process of goods, and improve the sales volume and management efficiency of merchants.

In an optional solution of the present application, the monitoring terminal is any one or more of the following devices: wifi detection device, RFID device, NFC device, and wireless communication device based on 433/866 protocol.
