One end, the other end of the second driving coil 63 ground connection.
The normal open switch 51 of inspection switch is closed when elevator is in normal condition, and normally closed switch 52 disconnects；Electricity
The normal open switch 51 of inspection switch is disconnected when ladder is in inspecting state, and normally closed switch 52 is closed.
Thermal infrared human body sensor according to body temperature detect car top position whether someone, including for examining
Your optical filter of luxuriant and rich with fragrance mud for survey ultrared passive type infrared probe, coordinating with passive type infrared probe and with luxuriant and rich with fragrance mud
The infrared induction source that your optical filter coordinates.Human body has constant body temperature, typically at 37 degree, so can send
Specific wavelength 10UM or so infrared ray, passive type infrared probe is exactly the 10UM left sides for detecting human-body emitting
The infrared ray of right (i.e. 9UM~11UM) and be operated.The 10UM of human-body emitting or so infrared ray
By being gathered after that optical filter enhancing of luxuriant and rich with fragrance mud on infrared induction source.
The other structures of embodiment one are referring to prior art.
Embodiment two
Using the infrared elevator car top spatial operation safety system of embodiment one, now illustrate that embodiment two is infrared
Elevator car top spatial operation method for security protection, including：
S1, human body enter car top, and thermal infrared human body sensor senses human body specific wavelength infrared ray (i.e.
Wavelength be 9UM~11UM infrared ray) when the 3rd pin 3 output 24V voltages, the first driving coil 45
The voltage of first coil contact 451 be 24V, the first driving coil 45 drives the first normally opened contact 41 and the
Two normally opened contacts 42 are connected, and the 3rd normally opened contact 43 and the 4th normally opened contact 44 are connected；Now elevator master control
The input JX of system senses 24V voltages, realizes that the signal for sending thermal infrared human body sensor is passed
It is defeated to arrive elevator master control system；Now elevator enters and is maintained at maintenance model.
S2, when embodiment one be provided with the inspection switch DJK and time relay KT when, if inspection switch DJK
Normal open switch 51 close, normally closed switch 52 disconnects, maintainer enter car top after, manual toggle inspection
Switch DJK is repaiied, realizes that normal open switch 51 disconnects, normally closed switch 52 is closed, now time relay KT
It is not powered on, the input JX of elevator master control system connects the first pin 1 by normally closed switch 52, and first is normally closed
The normally-closed contact 62 of contact 61 and second is connected；This structures and methods realizes that the safety of human body during to maintenance does two
Secondary protection, prevents that thermal infrared human body sensor is not normal, it is ensured that the input JX electricity of elevator master control system
Press as O, active system one directly receives the signal that thermal infrared human body sensor is sent, elevator is in inspection
Repair a die formula.
After S3, maintenance are finished, maintainer stirs inspection switch DJK, realizes that normal open switch 51 is closed, often
Make and break is closed 52 and disconnected, and now time relay KT is powered and starts timing.
S4, maintainer exit car top, because the sensing of thermal infrared human body sensor is drawn less than human body, the 3rd
The voltage of pin 3 is 0, and the first normally opened contact 41 and the second normally opened contact 42 disconnect, the He of the 3rd normally opened contact 43
4th normally opened contact 44 disconnects；The input JX of elevator master control system voltage is 0, and elevator recovers normal mode
Formula.After time relay KT timing reaches preset time value, the first normally-closed contact 61 and second is normally closed tactile
Point 62 disconnects, and easy access personnel withdraw from car top.
The present embodiment is had the following advantages that using above structure：
1st, entered using maintainer without special action before car top, elevator door is once opened, thermal infrared people
Body induction sensor senses human body specific wavelength infrared ray, and elevator has been put into maintenance model, do not deposited immediately
Forgetting the possibility of operation.Prevent maintainer from entering after car top, elevator accidental activation causes maintainer
Body is sheared by elevator, and the personal safety of protection maintainer, eliminates safe hidden trouble really.
2nd, using inspection switch DJK and time relay KT structures, second protection is done, is ensured in maintenance
The safety of maintainer, while realizing that maintenance model is exited in elevator delay, is exited beneficial to maintainer completely
Car top.
The invention is not limited in above-mentioned embodiment, if the various changes or modification to the present invention are not departed from
