Abstract
It is provided a method for detecting people, the method being performed by a people detector provided by a doorway. The method comprises the steps of: receiving an open signal indicating that a door of the doorway is open; setting a people sensor of the people detector in an active mode based on receiving the open signal; detecting when a person passes through the doorway, using the people sensor; receiving a closed signal indicating that the door of the doorway is closed; transmitting a result of the step of detecting, wherein the step of transmitting is performed based on receiving the closed signal; and setting the people sensor in a power save mode based on receiving the closed signal.
Claims8
A method for detecting people, the method being performed by a people detector provided by a doorway, wherein the people detector comprises an energy harvesting device for capturing energy from door opening and/or door closing, the method comprising:
- receiving an open signal indicating that a door of the doorway is open;
- causing a people sensor of the people detector to transition from a power save mode to an active mode based on receiving the open signal;
- detecting when a person passes through the doorway, using the people sensor, and detecting a direction of the person passing through the doorway;
- determining both a counter of all entries since a last transmitted result and a counter of all exits since the last transmitted result, wherein at least one of:
- the counter of all entries since the last transmitted result comprises an accumulation of multiple entries since the last transmitted result or the counter of all exits since the last transmitted result comprises an accumulation of multiple exits since the last transmitted result;
- receiving a closed signal indicating that the door of the doorway is closed;
- transmitting a result of detecting, wherein transmitting is performed based on receiving the closed signal, and wherein the result contains both the counter of all entries and the counter of all exits, since the last transmitted result;
- and
- setting the people sensor in the power save mode based on receiving the closed signal.
A people detector for detecting people, the people detector being configured to be provided by a doorway, the people detector comprising:
- a processor;
- a people sensor;
- and
- a memory storing instructions that, when executed by the processor, cause the people detector to:
- receive an open signal indicating that a door of the doorway is open;
- cause the people sensor to transition from a power save mode to an active mode based on receiving the open signal;
- detect when a person passes through the doorway, using the people sensor, and detect a direction of the person passing through the doorway;
- determine both a counter of all entries since a last transmitted result and a counter of all exits since the last transmitted result, wherein at least one of:
- the counter of all entries since the last transmitted result comprises an accumulation of multiple entries since the last transmitted result or the counter of all exits since the last transmitted result comprises an accumulation of multiple exits since the last transmitted result;
- receive a closed signal indicating that the door of the doorway is closed;
- transmit a result of detecting, based on receiving the closed signal, wherein the result contains both the counter of all entries and the counter of all exits, since the last transmitted result;
- and
- set the people sensor in the power save mode based on receiving the closed signal.
A non-transitory computer readable medium storing a computer program for detecting people, the computer program comprising computer program code which, when run on a people detector provided by a doorway, causes the people detector to:
- receive an open signal indicating that a door of the doorway is open;
- cause a people sensor of the people detector to transition from a power save mode to an active mode based on receiving the open signal;
- detect when a person passes through the doorway, using the people sensor, and detect a direction of the person passing through the doorway;
- determine both a counter of all entries since a last transmitted result and a counter of all exits since the last transmitted result, wherein at least one of:
- the counter of all entries since the last transmitted result comprises an accumulation of multiple entries since the last transmitted result or the counter of all exits since the last transmitted result comprises an accumulation of multiple exits since the last transmitted result;
- receive a closed signal indicating that the door of the doorway is closed;
- transmit a result of detecting, based on receiving the closed signal, wherein the result contains both the counter of all entries and the counter of all exits, since the last transmitted result;
- and
- set the people sensor in the power save mode based on receiving the closed signal.
