Abstract
The invention discloses a method for detecting faint of a person. The method comprises the steps that a microwave sensor (1) monitors whether a user is in a fainted state in an elevator; when the user in the elevator is detected to be fainted, the microwave sensor (1) transmits information to a controller (2), the controller (2) starts an in-lift-car alarm device (3), and the in-lift-car alarm device (3) interacts with the user; if the user responds to the in-lift-car alarm device (3), the controller (2) judges that the user is not fainted, an external helping device (4) does not need to be started, and if the user does not respond within N seconds, the external helping device (4) is started for seeking help to the outside. The method is simple in structure, economical and practical; if the user is under an unforeseen circumstance, it is guaranteed that the user can obtain help in the first time; the method has an interactive reminding function, and misoperation is prevented.
Description
Technical field
The invention discloses a kind of method that testing staff falls in a swoon, be applied to protection when personnel fall in a swoon in elevator, belong to elevator applications field.
Background technology
The modern life is along with the development in city, and high building stands in great numbers, and skyscraper be unable to do without elevator, and the dependence of modern to elevator is more and more higher.Along with China's population aging degree aggravation and rhythm of life accelerate increasing of lower burst disease, the safety of personnel in elevator is important all the more.Elevator is when serving for people, and safety problem needs more to pay close attention to, and this is not only moral care, still avoids the required of legal dispute.
Elevator is a kind of special and important trip instrument, and when not having other people to use in elevator a period of time, elevator door is shut again automatically, user of service happens suddenly and surprisingly falls in a swoon, now around there is no others to rescue, the best opportunity of rescue will be missed, especially the elderly, illness is with it more, picture heart disease, coronary heart disease, apoplexy, cerebral apoplexys etc., all can faint suddenly.Patient can miss the Best Times of rescue in car because Nobody Knows, endanger the safety of user of service time serious.
Existing elevator great majority do not install video monitoring function, even if having also is that monitor staff by Control Room finds unforeseen circumstances by manual observation, and make respective reaction, this kind of mode requires that monitor staff dig-ins monitored picture for a long time, when the giant-screen of Control Room is more simultaneously, careless omission is unavoidable.
This situation is above the problem that present elevator needs in the face of the public of the public, particularly aging society to consider in advance to solve.
Summary of the invention
The present invention is directed to deficiency of the prior art, propose a kind of method that testing staff falls in a swoon, whether detection arrangement monitors user of service is in the state of falling in a swoon, if then point out user of service by warning device in sedan-chair 3, if there is response controller 2 outwards not report to the police, if nonreply controller 2 is reported to the police from trend room security or 110 or 120, ensure that user of service got help in the very first time.
The method that testing staff falls in a swoon, is characterized in that, the step of the method that described a kind of testing staff falls in a swoon is as follows:
1) monitor user of service in elevator with microwave remote sensor 1 and whether be in the state of falling in a swoon;
2) when detecting that in elevator, user of service falls in a swoon, information is sent to controller 2 by microwave remote sensor 1, and controller 2 starts warning device 3 in sedan-chair, and in sedan-chair, warning device 3 is by carrying out alternately with user of service;
3) if user of service replys warning device 3 in sedan-chair, controller 2 judges that user of service does not fall in a swoon, and without the need to starting external help request device 4, if user of service's not response within N time second, starting external help request device 4 and externally seeking help.
The microwave remote sensor 1 that in described monitoring elevator, whether user of service is in the state of falling in a swoon also is parallel with photoelectricity diffuser reflection sensor 10 or human induction switch 11, the sensor of described human induction switch 11 for utilizing infrared ray, heat discharge prin-ciple to respond to physical activity information, described photoelectricity diffuser reflection sensor 10 or human induction switch 11 are connected with controller 2.
Described controller 2 is controller in elevator or external controller, and described external controller is the one in MCU, DSP, PLC, CPLD, FPGA.
In described sedan-chair, warning device 3 comprises light curtain equipment 31, sound interactive device 32 or light curtain equipment 31, button interaction device 33 or light curtain equipment 31, sound interactive device 32, button interaction device 33, and described light curtain equipment 31 is projector 311 and acrylic board 312.
Described external help request device 4 starts room security warning or 110 interlink warnings or 120 medical rescues or is wirelessly transferred to mobile phone, Internet of Things.
Described controller 2 connects opening or closing of elevator door lock signal, and the beginning of sensor, controller 2 work is controlled by door lock of elevator closing signal, and the reset signal of controller 2 is disconnected by door lock of elevator and controlling.
Described controller 2 connects normally/overhaul signal port, and when elevator normally uses, whether testing staff falls in a swoon, and when overhauling elevator, controller 2 does not run the function whether testing staff falls in a swoon.
Described microwave remote sensor 1 or photoelectricity diffuser reflection sensor 10 or human induction switch 11 are arranged on the top of lift car.
Advantage of the present invention:
1) structure is simple, economical and practical;
