Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model
Limitation.
Falling for the fall detection system of the water heater of the utility model embodiment and water heater described below in conjunction with the accompanying drawings
Detection method.
Fig. 1 is the block diagram according to the fall detection system of the water heater of the utility model embodiment.Such as Fig. 1 institutes
Show, the fall detection system of water heater includes radar 100 and water heater 200.
Wherein, radar 100 is arranged in the room residing for water heater 200, and radar 100 is used to sense residing for water heater 200
Room in human body motion state；Water heater 200 includes flow detection unit 10 and the control being connected with flow detection unit 10
Unit 20 processed, flow detection unit 10 are used for the water flow for detecting water heater, and control unit 20 is used for going out in water heater 200
Control radar 100 starts to sense the motion state of human body when water-carrying capacity is more than preset flow threshold value, and does not sense in radar 100
Judge to fall when reaching the first preset time threshold to mobile human body and duration.
It should be noted that radar 100 can be Doppler microwave radar, Doppler's Microwave Velocity principle is by Microwave emission
To moving object, moving object produces reflection or scattered wave, and due to Doppler effect, reflection or scattered wave can produce Doppler's frequency
Move, the motion that can obtain moving object after electronic processing circuit again is mixed using caused frequency displacement ripple and this vibration wave
Speed.Thus, in embodiments of the present invention, radar 100 is arranged in the room (such as bathroom) residing for water heater 200 Nei, led to
The motion state of human body in the room residing for sensing water heater 200 is crossed, such as senses mobile human body or is not sensed by movement
Human body, and then judge whether situation about falling.
It should be noted that radar 100 can be Doppler microwave radar, Doppler's Microwave Velocity principle is by Microwave emission
To moving object, moving object produces reflection or scattered wave, and due to Doppler effect, reflection or scattered wave can produce Doppler's frequency
Move, the motion that can obtain moving object after electronic processing circuit again is mixed using caused frequency displacement ripple and this vibration wave
Speed.Thus, in embodiments of the present invention, radar 100 is arranged in the room (such as bathroom) residing for water heater 200 Nei, led to
The motion state of human body in the room residing for sensing water heater 200 is crossed, such as senses mobile human body or is not sensed by movement
Human body, and then judge whether situation about falling.
Fig. 3 is according to the flow chart of the fall detection method of the water heater of the utility model embodiment, as shown in figure 3, hot
The fall detection method of hydrophone comprises the following steps：
S1：Detect the water flow of water heater.
S2：When the water flow of water heater is more than preset flow threshold value, control radar starts.
S3：Pass through the motion state of human body in the room residing for radar sensing water heater.
S4：When radar is not sensed by mobile human body and the duration reaches the first preset time threshold, judge to occur
Fall.
It should be noted that radar can be Doppler microwave radar, Doppler's Microwave Velocity principle is to arrive Microwave emission
Moving object, moving object produces reflection or scattered wave, and due to Doppler effect, reflection or scattered wave can produce Doppler's frequency
Move, the motion that can obtain moving object after electronic processing circuit again is mixed using caused frequency displacement ripple and this vibration wave
Speed.Thus, in the utility model embodiment, radar is arranged in the room (such as bathroom) residing for water heater Nei, passed through
Sense the motion state of human body in the room residing for water heater, such as sense mobile human body or be not sensed by mobile people
Body, and then judge whether situation about falling.
Specifically, by detecting the water flow of water heater, judge whether the water flow of water heater is more than default stream
Threshold value is measured, if the water flow of water heater is less than or equal to preset flow threshold value, judges that water heater is not in out water state,
Continue the water flow of detection water heater；If the water flow of water heater is more than preset flow threshold value, judge at water heater
In going out water state, water state time control radar start is in out to sense the motion state of human body in water heater, i.e., is opened in user
Control radar starts to sense the motion state of human body after beginning bathing, in radar detection process, if be not sensed by mobile
Human body senses that user remains static and the duration reaches the first preset time threshold, then judges to fall, from
And prevent during bather's bathing because take thing etc. temporarily from and caused by erroneous judgement.Wherein, the first preset time can be more than or equal to 10s.
According to one embodiment of the present utility model, the fall detection method of water heater also includes working as judging to fall
When, control the alarm unit of water heater to send a warning, so as to remind neighbouring personnel to give first aid to bather in time.
It should be noted that alarm unit can be by sending information realization alarm to mobile terminal, also can be by sending honeybee
Ring realizes buzzing alarming or sends indicator lamp alarm etc. by battery capacity indication lamp, so that rescue personnel can obtain bather in time
The information of tumble, and bather is given first aid to.
According to one embodiment of the present utility model, the fall detection method of water heater also include when water flow is less than or
When being more than the second preset time threshold equal to preset flow threshold value and duration, control radar is closed.Wherein, second it is default when
Between threshold value be greater than or equal to 15 minutes.
It should be appreciated that the water flow of water heater is less than or equal to preset flow threshold value and the duration is more than second
During preset time threshold, as water heater is closed or during non-bathing state.Now, control radar is closed to prevent because of unmanned bathing
And the erroneous judgement of tumble state is caused, and save the energy.
For example, by detecting the water flow of water heater, heat is used in bather (such as old man or individuals with disabilities)
When hydrophone carries out bathing, the water flow of the water heater detected is more than preset flow threshold value, and now, control radar starts, thunder
It is kept in motion up to the human body i.e. user for sensing motion.In radar detection process, when radar is not sensed by mobile people
When body is that user remains static and the duration reaches the first predetermined threshold value (such as 10s), judge to fall, now,
Sent a warning to other rooms, so as to remind neighbouring personnel to give first aid to bather in time.
In summary, according to the fall detection method of the water heater of the utility model embodiment, by detecting water heater
Water flow, then when the water flow of water heater is more than predetermined threshold value, control radar starts, and senses water heater by radar
The motion state of human body in residing room, when radar is not sensed by mobile human body and duration big first preset time difficult to understand
During threshold value, judge to fall.Thereby, it is possible to situation accurate, that timely judgement is fallen, and then can avoid because falling
The contingency of generation.
