Technical field
The utility model is related to a kind of sensor detecting devices, more particularly, to a kind of hand of monitoring indoor occupant fatigue strength
Ring and system.
Background technology
Now as the increase of social pressures, the operating time of people also constantly increase, many staff were in
The sub-health state for spending fatigue, has huge harm, over fatigue to be possible to that a variety of diseases can be caused the health of human body,
What is more can cause tragedy as overworking death.In fatigue, often body harmony is poor, cerebral dominance power declines, pays attention to by people
Power divides decrease of memory, retardation of thinking, slow in one's movements, thus is easy to error in judgement, to cause the accident.Now, Hen Duogong
White collar, programmer etc. clerk are taken charge of due to working long hours, it is difficult to judge their working strength and degree of fatigue,
It is easy to the accident died suddenly in this way.Therefore, the development of the bracelet of monitoring indoor occupant working strength and fatigue strength has non-
Normal actual meaning and extensive purposes.
There are many kinds of the methods of present detection human-body fatigue degree, and some is analyzed by detecting blood of human body volume information
Human-body fatigue degree, some analyze human-body fatigue degree by the content of assay ptyalin, and some is by detecting people's
Language analyzes human-body fatigue degree with brain activity, more also analyzes people by taking question ＆ answer, measurement heart method etc.
Body fatigue strength.Although these methods may be used, but have the shortcomings that certain, is not that accuracy is not high, exactly applies
It is cumbersome.
Application publication number is that the Chinese patent of 105788175 A of CN discloses a kind of driver tired driving early warning bracelet,
It is worn in driver's wrist, including bracelet main body and bracelet connect, bracelet main body includes power module, attitude transducer, pulse
Sensor, clock module, vibrating motor, motor driving, microcontroller and voice alarm module, each module are electric with microcontroller
Property be connected, attitude transducer is to measure the 3-axis acceleration of driver's arm, and pulse transducer is measuring the heart of driver
Rate.The state that driver is detected by attitude transducer and pulse transducer passes through when finding that driver is in fatigue state
Voice and vibrating motor prompt driver.However the early warning bracelet has a single function, and only prompts to drive by the voice of itself and vibration
The person of sailing does not carry out comprehensive early warning and protection.

The wireless transceiver is the SX1278 chips with Lora networking capabilities.
The bracelet band is buckled equipped with needle and pin hole.
A kind of monitoring system of the bracelet with the monitoring indoor occupant fatigue strength, including bracelet, concentrator, routing
Device, server and client side, the wireless transceiver in bracelet are connect with concentrator, router, server and client side successively, nothing
Pass through Lora network connections between line transceiver and concentrator.
SX1278 chips built in the concentrator and for the ESP8266 wireless modules with router communication.
The client includes PC and mobile phone.
Compared with prior art, the utility model has the following advantages：
(1) wireless transceiver is also built-in in bracelet main body, wireless transceiver is connect with control module, can will be collected
Signal is sent out by wireless transceiver, to remotely obtain the state of monitored personnel, is conducive to implement comprehensive early warning
And protection.
(2) wireless transceiver is the SX1278 chips with Lora networking capabilities, therefore concentrator can obtain itself and nothing
RSSI signal strength informations between line transceiver carry out in all directions monitored personnel to be positioned to bracelet main body
Monitoring.
(3) system client is PC and mobile phone, can conveniently check monitored personnel's state.

Fig. 2 is the component connection block diagram that the present embodiment monitors system；
Fig. 3 is that the present embodiment monitors working-flow figure；
Fig. 4 is that the present embodiment monitors system concentrator positioning schematic.
Specific implementation mode
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, gives detailed embodiment and specific operating process, but the guarantor of the utility model
Shield range is not limited to following embodiments.
Embodiment
As shown in Figure 1, a kind of bracelet of monitoring indoor occupant fatigue strength, including bracelet main body 2 and bracelet band 1, bracelet master
It is built-in with the pulse transducer and control module of interconnection in body 2, wireless transceiver, bracelet are also built-in in bracelet main body 2
Band 1 and needle buckle 3 and pin hole 4 for bracelet main body 2 to be worn on hand, make the skin-proximal pulse as far as possible of bracelet main body 2；Hand
2 inside of ring main body is embedded with pulse transducer and LORA transmitting modules, is respectively used to acquisition human pulse signal and will collect
Data concentrator is emitted to by LORA wireless technologys；
In Fig. 2, indoor occupant fatigue monitoring system forms monitoring system, multinode by multinode acquisition module, concentrator
Acquisition module acquires pulse signal using Pulse Sensor.The collected multi-parameter signals of sensor enter in STM32L476
Carry out signal extraction, interference processing and analysis of fatigue；Concentrator acquires each node data, and clothes are passed to by existing wireless WIFI
Business device.Monitoring system can carry out the cloud server that access by PC and cell phone application, if there is Indexes Abnormality, monitoring
System will alarm, and remind related personnel to take measures, prevent fortuitous event.
In Fig. 3, system sets pulse A/D sampling initialization first, and then timer interruption starts, and completes Pulse-Parameters and adopts
Sample, by calling 256 points of the FFT subfunctions by built-in DSP to carry out spectrum analysis to the pulse signal acquired；Most
Afterwards, amount of frequency spectrum is defined than determining the tired shape of people for high order spectrum energy energy and with the spectrum energy ratio K of the first main peak
State.Pulse is acquired, is filtered, calculating heart rate value with calculating duty cycle.In order to avoid being interfered because of acquisition, using anti-impulse disturbances system
An a reference value sampling is carried out after the completion of system initialization to carry out pulse time domain under normal condition for the basis that the later stage judges
FFT transform is the information such as each secondary frequency spectrum, spectrum energy as shown in figure 3, being concentrated on by known to experiment 99% or more energy
Within 10Hz, using FIR filter realize band-pass function, by tool box fdatool obtain digital filter coefficient after
STM32L4 runs arm_fir_f32 functions, completes digital filtering.By analyzing the first main peak S (1) and other peaks spectrum energy S
(2), S (3), S (4) relationship can learn measured's fatigue state.Define spectrum energy COEFFICIENT K=(S (2)+S (3)+S
(4))/S(1)。
In order to ensure low-power consumption, the concentrator of this system uses timing 3min gathered datas, when in other times section node
1-N is in dormant state；When gathered data, concentrator in a broadcast manner, sends the wake-up code with employee's work number, institute first
Node whether can receive corresponding work number and wake up code and work number is compared be to wake up oneself, continue if work number is not inconsistent
Sleep, if work number meets, which wakes up immediately enters working condition, and after wake-up, concentrator can then send reading and refer to
The working node waken up is enabled, again to concentrator returned data after receiving instruction, subsequently enters sleep state to reduce energy consumption.
In Fig. 4, employee is overworked the timely discovery of body occurs in order to ensure to occur, and necessity positioning is indispensable
, the positioning of GPS indoors can not ensure at all, and the concentrator of this system is known that work by reading the value of register RSSI
Number location information, convenient for first time emergency case rescue.
