Description
Technical Field

Background
The passenger flow analysis refers to the analysis of information such as the number, identity and the like of the passenger flow in the place. With the rise of digital operation, demands for passenger flow analysis are increasing in off-line markets, stores, public transportation and other places. The passenger flow analysis equipment provides accurate professional passenger flow data for an operator, and helps the operator to analyze the passenger flow with scientific basis. The analysis conclusion is fed back to daily operation and management, so that the decision is more dependent and quantifiable.
In passenger flow analysis, target detection aiming at human body targets is the basis of subsequent statistics and analysis. In the prior art, a machine vision scheme based on a camera technology is mainly used, and meanwhile, some schemes based on technologies such as laser and thermal imaging are provided. The technical scheme based on the camera technology or other technical schemes have the defect of too large power consumption, usually a wired power supply mode is needed, and the power consumption is difficult to reduce to the degree of using a battery for power supply, so that the cost for implementing and deploying the passenger flow analysis equipment is high, and the passenger flow analysis equipment is inconvenient.
Specifically, the arrangement of power lines and network lines is a large resistance of a passenger flow analysis system, the construction cost required by passenger flow analysis equipment for arranging a point location can reach 500-1500 RMB, and holes are punched in the arranged point location for installation, so that negative effects are easily brought to the attractiveness of places (such as store entrances).
Therefore, how to reduce the power consumption of the passenger flow analysis device (especially in the passenger flow detection link) to the extent that the power can be supported by the battery power supply is a problem to be solved urgently in the field.
In the prior art, the purpose of energy saving is usually achieved by reducing the data volume (for example, extracting frames or reducing the acquisition frame rate) and/or by using some components with low power consumption and high performance, but the effect is not obvious and is far from being enough to reduce the power consumption of the passenger flow analysis equipment to the extent that the power consumption can be supported by a battery.
The PIR sensor is a human body pyroelectric infrared sensor. The pyroelectric effect refers to a charge release phenomenon that polarization intensity shows with temperature change. The body temperature of a human body is usually about 37 degrees celsius, and electromagnetic waves having a wavelength of about 10 μm (belonging to the infrared band) are emitted based on this temperature.

Electromagnetic waves with the wavelength of about 10 micrometers emitted by a human body are enhanced by a Fresnel filter and then are gathered on an induction source, the induction source of a PIR sensor usually adopts a pyroelectric element, the temperature of the pyroelectric element changes after the electromagnetic waves radiated by the human body are received, the pyroelectric element loses charge balance due to the temperature change, charges (namely pyroelectric effect) are released outwards, and the released charges are detected and processed by a subsequent circuit, so that the detection of surrounding human body targets is realized. PIR sensors have low power consumption, typically only on the order of microamperes.

Detailed Description
As can be seen from the analysis of the background art, in the prior art, the passenger flow analysis device usually detects the passenger flow through machine vision based on a camera technology or based on a laser/thermal imaging technology, which has the defect of too large power consumption, and usually needs to use a wired power supply mode, so that it is difficult to reduce the power consumption to a level of using a battery to supply power, which results in higher cost and inconvenience for implementing and deploying the passenger flow analysis device.
Specifically, the arrangement of power lines and network lines is a large resistance of a passenger flow analysis system, the construction cost required by passenger flow analysis equipment for arranging a point location can reach 500-1500 RMB, and holes are punched in the arranged point location for installation, so that negative effects are easily brought to the attractiveness of places (such as store entrances).
In the prior art, the purpose of energy saving is usually achieved by reducing the data volume (for example, extracting frames or reducing the acquisition frame rate) and/or by using some components with low power consumption and high performance, but the effect is not obvious and is far from being enough to reduce the power consumption of the passenger flow analysis equipment to the extent that the power consumption can be supported by a battery.
The inventor considers that, in the aspect of low power consumption control, the main reason that the power consumption of the passenger flow analysis device is too large is that the power consumption is too large during the collection of the device, and the device needs to be in the collection state for a long time to avoid missing the target because the occurrence of the collected target cannot be predicted.
According to the passenger flow analysis device, whether a human body target appears or not is detected in real time through the PIR sensor with extremely low power consumption, the thermal imaging sensor with high power consumption and other components in the passenger flow analysis device are awakened only after the PIR sensor detects that the human body target appears, and most of the components in the passenger flow analysis device are in a low power consumption mode or a dormant or power-off state under the condition that the PIR sensor does not detect that the human body target appears, so that the power consumption of the passenger flow analysis device is greatly reduced.
In order that those skilled in the art will better understand and realize the present invention, the following detailed description is given by way of specific embodiments with reference to the accompanying drawings.
Example one
As described below, an embodiment of the present invention provides a method for controlling a passenger flow analysis device.
Referring to a flow chart of a control method of the passenger flow analysis device shown in fig. 1, the following detailed description is made through specific steps:
s101, detecting whether a human body target appears in real time through first detection equipment.
Wherein the first detection device is a PIR sensor. The PIR sensor is a human body induction sensor with extremely low power consumption and can be started for a long time.
The first detection device continues to detect, and when the first detection device detects the presence of the human target, the process proceeds to step S102.
If the first detection device does not detect the presence of a human target for a second, continuous period of time, the process proceeds to step S103.
And S102, controlling the second detection equipment to collect data and continuing for a first time period.
And if the first detection equipment detects that the human body target appears, controlling the second detection equipment to acquire data and continuing for a first time period.
Wherein the second detection device is a data acquisition device. The second detection device may consume a much higher power than the first detection device.
In some embodiments, the data acquisition device may specifically be a thermal imaging sensor or a camera or a radar or pyroelectric array sensor.
In some embodiments, the detection range of the first detection device completely covers and is larger than the detection range of the second detection device,
in some embodiments, the wake-up signal is emitted when the first detection device detects the presence of a human target. The processor of the passenger flow analysis device wakes up (or powers on or powers back on) in response to the received wake-up signal, and the processor wakes up the second detection device.
Furthermore, when the first detection device detects that the human body target appears, the first detection device can directly or indirectly wake up and control the communication module and the storage module of the passenger flow analysis device to work for a first time period. Similarly, the processor is used to wake up/power on the communication module and the memory module, or the processor is used to control the power supply module to power on the communication module and the memory module.
In some embodiments, the durations of the first time period and the second time period may be set on the passenger flow analysis device in advance.
In some embodiments, the first time period and the second time period may be equal length time periods, but the invention is not limited thereto.
S103, the second detection device enters a low power consumption mode or is in a dormant state or is powered off.
And if the first detection device does not detect the presence of the human body target within a second continuous time period, the second detection device enters a low power consumption mode or is in a dormant state or is powered off.
In some embodiments, there may be no need to control the second detection device to enter the low power mode through the control signal, and the second detection device does not receive the wake-up signal again within the second time period, and then enters the low power mode.
The first detection device continues to perform real-time detection (i.e., step S101 is continuously performed regardless of whether the first detection device detects the presence of the human target).
After the second detection device enters a low power consumption mode or is in a dormant state or is powered off, the state is maintained until the second detection device is awakened again (or powered on again) after the first detection device detects that a human body target appears.
Similarly, if the second detection device does not receive the wake-up signal again within the second time period, the communication module and the storage module of the passenger flow analysis device may enter a low power consumption mode or sleep or power off, except that the second detection device enters the low power consumption mode. After entering a low power consumption mode or being dormant or powered off, the communication module and the storage module of the passenger flow analysis device keep the state until the first detection device detects that a human body target appears, and then wakes up (or powers on again) the processor, the second detection device, the communication module and the storage module again.
Further, in some embodiments, if the first detection device detects the presence of the human target during the data acquisition process of the second detection device, the process proceeds to step S104.
And S104, resetting the time for acquiring the data by the second detection equipment to be a first time period.
By adopting the scheme of this embodiment, the power consumption of the passenger flow analysis device can be reduced to the extent that the power can be supported by battery power supply, that is, the power can be supplied by ac or dc power supply, or by battery power supply (the invention is not limited to this). In some embodiments, the passenger flow analysis device is powered by a battery, or at least the first detection device, the processor, the communication module, and the storage module in the passenger flow analysis device are powered by a battery.
The above description of the technical solution shows that: in this embodiment, whether a human target appears is detected in real time by the PIR sensor with extremely low power consumption, the thermal imaging sensor with high power consumption and other components in the passenger flow analysis device are awakened only after the PIR sensor detects that the human target appears, and most of the components in the passenger flow analysis device are in a low power consumption mode or a sleep or power-off state under the condition that the PIR sensor does not detect that the human target appears, so that the power consumption of the passenger flow analysis device is greatly reduced.
Furthermore, the power consumption of the passenger flow analysis equipment is reduced to the extent that the passenger flow analysis equipment can be supported by battery power supply, and the battery power supply is adopted, so that the labor and cost required by the arrangement of a power line are saved, and the negative influence of the arrangement of the power line on the attractiveness of a place is avoided.
