Output, such as connection alternating current carry out decompression by 4 converter of power supply and alterating and direct current is converted.
Reflection infrared sensor 1 detects target object information in toilet, and the result that will test is transferred to controller 2,
Controller 2 handles testing result, processing result is transferred to radio transmitting device 3, radio transmitting device 3 is transferred to outer
The receiving end in portion.
When above-mentioned toilet detection system includes reflection infrared sensor 1, controller 2, radio transmitting device 3 and electricity
When source 4 is located in a fixed device, as shown in Fig. 2, the device includes a shell, the reflection infrared sensor 1, control
Device 2, radio transmitting device 3 and power supply 4 are located in shell, and radio transmitting device 3 is located at shell rim, convenient for wireless transmission dress
The antenna set on 3 externally carries out data transmission, and antenna can be the either external antenna of built-in antenna 31, when for external antenna
When, it is typically provided with the antenna socket of external antenna.Reflection infrared sensor 1 is normally at shell rim, and remote as far as possible
From power supply 4, the heat for avoiding power supply 4 from generating when discharging influences the detection accuracy of reflection infrared sensor 1.This is set to fixation
Toilet detection system in device, can be along the metope installation or ceiling peace right above the position of lavatory according to actually detected demand
Dress, convenient for carrying out detection judgement with the presence or absence of target object in toilet.
In the present embodiment, by reflection infrared sensor 1 detect toilet in whether presence of people, pass through controller
The position encoded determining reflection infrared sensor 1 in the toilet stored in 2 detect whether the location of the toilet of someone,
Reflection infrared sensor 1 is detected that result and corresponding position are sent to exterior terminal equipment through radio transmitting device 3, is used
The service condition of toilet is checked at family by terminal device, so that user is avoided to need to check whether someone to toilet in person,
Avoid knocking at the door confirm toilet whether embarrassment caused by someone.
Further, in an embodiment of the utility model toilet detection system, as shown in figure 3, the toilet
Radio transmitting device 3 and associated cloud platform or user terminal communication connection, the use of the cloud platform and registration in detection system
The connection of family end communication.
In associated cloud platform, with toilet detection system radio transmitting device 3 can effective communication, it is general by advance
Communication connection registered in advance.User terminal may include the mobile terminals such as mobile phone, PAD, computer, Intelligent bracelet here.With cloud platform
The user terminal of registration is generally equipped with corresponding application program either web interface on user terminal, by application program or
Communication connection is carried out between person's web interface and cloud platform, what is effectively communicated is the user terminal of registration.
Radio transmitting device 3 and external cloud platform or user terminal communication connection, wherein associated cloud platform generally has
Standby storage and data processing function, can store and process the information received, user's end communication of cloud platform and registration
Connection, is transferred to user terminal for the information indirect that radio transmitting device 3 transmits, shows on user terminal, and then can pass through use
Family end obtain the toilet that detects of reflection infrared sensor 1 whether the status information of someone.Furthermore wireless communication apparatus can
Directly with user terminal communication connection, directly to transmit information to user terminal and be shown.
It in the present embodiment, will be wireless by external cloud platform or user terminal and 3 communication connection of radio transmitting device
The collected information of transmitting device 3 is transferred to user terminal and is shown, understands the service condition of toilet in real time convenient for user.
Optionally, in an embodiment of the utility model toilet detection system, the toilet detection system is also wrapped
Include timer, the timer include calculate reflection infrared sensor 1 detect target object duration the first timer and
Calculate the second timer that target object duration is not detected in reflection infrared sensor 1；The timer and controller 2 are electrically
Connection.
First timer detects that the duration of target object carries out timing to reflection infrared sensor 1, calculates current mesh
Mark object is in the duration of current toilet, can influence to avoid overlong time of the current target object in current toilet
The normal use of toilet.Further, instantaneous speech power, the instantaneous speech power are set in toilet detection system
It is set to inside toilet, reaches regular hour threshold value when the first timer carries out timing, show that current target object is being worked as
Overlong time in preceding toilet, controller 2 control instantaneous speech power output and remind.
The duration that target object is not detected to reflection infrared sensor 1 in second timer carries out timing, calculates current
Nobody duration for using of toilet, avoids current toilet is unmanned for a long time from using, reflection infrared sensor 1, which continues working, to be made
The service life of reflection infrared sensor 1 is wasted and shortened at power supply 4.Reach certain when the second timer carries out timing
When time threshold, shows that current toilet is unmanned for a long time and use, current control information is transferred to controller 2, controller 2 is controlled
Reflection infrared sensor 1 processed enters low energy consumption state or dormant state.
In the present embodiment, by the setting of timer, current target object residence time mistake in current toilet is avoided
The long normal use for influencing toilet, or avoid current toilet is unmanned for a long time from using, reflection infrared sensor 1 continues
Work causes the waste of electric energy.
