The invention greatly improves the existing backward mode of man-to-man dialogue contact or timely post-inspection by specialized personnel.
Description
Technical field
The present invention relates to a kind of supervising device, particularly a kind of positioning type body temperature device.
Background technology
Under abominable condition of work such as at present colliery, tunnel etc., to staff's location with detect most important.Improper ventilation in it, existing dedusting, toxin expelling facility fall behind, operating ambient temperature height, the temperature difference are big, and operation is round-the-clock, so bad working environment very easily damages operating personnel, occupational illness such as electric welder pneumoconiosis disease, manganese and compound poisoning thereof, nitrogen oxide poisoning, anthracemia, electroflash dermatitis, electric ophthalmia, noise-induced deafness, brass chill take place, serious threat staff's personal safety.But in present application, existing surveillance and control measure generally all is regularly to inspect the sentries by interpersonal dialogue contact or by the professional to follow the tracks of the staff.There is bigger contingency in this mode, brings very big hidden danger.Therefore the staff in it to be accurately located, and, their health be detected in real time in order to guarantee their life security.But because special condition of work brings difficulty for the detection of signal, it is very faint to produce signal blind zone or signal, can not send signal.
Summary of the invention
The present invention be directed to the problem of monitoring safety in the abominable working environment; a kind of positioning type body temperature node apparatus and method of work have been proposed; can accurately locate staff's position; and by real-time testing personnel's the vital sign of body temperature trans; qualitative, quantitative monitoring staff's physical signs, protection operating personnel's health.
Technical scheme of the present invention is: a kind of positioning type body temperature node apparatus, comprise radio-frequency communication module, power circuit, reset circuit, crystal oscillating circuit and serial communication module, and sensor assembly, low-power consumption chip CC2431 main control chip, sensor assembly is gathered the human body temperature signal and is input in the low-power consumption chip, transmit to host computer by radio-frequency communication module, power circuit is given chip power supply, crystal oscillating circuit provides the low-power consumption chip required frequency, emulator is by serial communication module and the communication of low-power scm chip, download write-in program, configuration data.
Described low-power consumption chip CC2431 chip wireless network location is based on the RSSI value, and the RSSI value increases and reduces along with distance.
A kind of positioning type body temperature node method of work, the node method of work may further comprise the steps:
1) Ding Wei transmitter is to open, and detects the RSSI value in real time;
2) detect RSSI value back by going out coordinate, real-time positioning with the known node position calculation;
3) receive the temperature data of body temperature trans;
4) judge whether temperature data surpasses the scope of setting, the scope that surpasses setting sends to host computer and carries out the data judgement; Normal condition is not defaulted as and goes beyond the scope, and will not need to send to host computer, continues monitoring.
Beneficial effect of the present invention is: a kind of positioning type body temperature node apparatus of the present invention and method of work; wireless communication technology, radio-frequency technique, electronic technology etc. have been adopted; use the positioning type body temperature node of up-to-date Zigbee technology; can obtain place and time that accident takes place in time, accurately; qualitative, quantitative monitoring staff's physical signs; protection operating personnel's health solves the security monitoring problem of operating personnel in the rugged surroundings.Improved at present the backward mode of regularly inspecting the sentries greatly by interpersonal dialogue contact or professional.

Embodiment
Positioning type body temperature node apparatus is a kind of node that the staff carries, and is a kind of function device lighter, that simplify.The main function of this device is real-time positioning and the temperature that detects health.The positioning type body temperature node apparatus structure wherein mainly contains following parts and forms: low-power consumption chip 1--CC2431, radio-frequency communication module 3, power circuit 7, reset circuit 6, crystal oscillating circuit 5 and serial communication module 2, and sensor assembly 4 as shown in Figure 1.This device is mainly by 1 control of low-power consumption chip, sensor assembly 4 is gathered the human body temperature signal and is input in the low-power consumption chip 1, transmit to host computer by radio-frequency communication module 3, power circuit 7 is given chip power supply, crystal oscillating circuit 5 provides the low-power consumption chip 1 required frequency, this device utilizes emulator to pass through serial communication module 2 and 1 communication of low-power scm chip, downloads write-in program, configuration data etc.
This location body temperature node apparatus is controlled by CC2431, by communicating by letter of P0_7 pin and body temperature trans, gather the human body temperature signal, the Zigbee radio circuit is integrated in chip internal, link to each other with antenna by impedance matching circuit, power supply is by No. 5 powered battery of 2 joints, and power light is indicated by light emitting diode.Require to select the crystal oscillator of 32M and 32.768K crystal oscillator frequency according to the inner structure of CC2431, the integrated single-chip microcomputer of chip internal is as microprocessor, major function has the signal that receives body temperature trans and sends a signal to host computer at any time, receives the order (read signal or write signal etc.) of host computer and send data, and realization is to the setting of the temperature range of baud rate, node address and the body temperature trans of radio frequency chip CC2431 etc.When not ordering, receive the data of body temperature trans, and judge, receive order and realize, when receiving the order of host computer, carry out the order that host computer sends immediately by the mode of interrupting according to the scope that is provided with time of each clock period.
CC2431 chip wireless network location is based on RSSI (Received Signal StrengthIndicator) value, the RSSI value increases and reduces along with distance, engine of positioning by RSSI can accurately calculate this node position according to the signal intensity and the known reference node location coordinate that receive, then positional information is sent to receiving end.
It is very low that this installs required power consumption, only needs two joint No.5 cells just can.Internal work may further comprise the steps:
1) Ding Wei transmitter is to open, and detects the RSSI value in real time;
2) detect RSSI value back by going out coordinate, real-time positioning with the known node position calculation;
3) receive the temperature data of body temperature trans;
4) judge whether temperature data surpasses the scope of setting, the scope that surpasses setting sends to host computer and carries out the data judgement; Normal condition is not defaulted as and goes beyond the scope, and will not need to send to host computer, continues monitoring.
Can reduce power consumption like this, prolong the serviceable life of node, the body temperature transmitter of radio frequency chip all cuts out, only when surpassing the scope of setting, the temperature data that receives body temperature trans just sends, normal condition is not defaulted as and goes beyond the scope, because judge in this node inside, do not need to send to host computer and carry out the data judgement, can reduce the power consumption of radio frequency chip so greatly.
