Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Obviously, described embodiment is only a part of embodiment of the utility model, rather than the embodiment of whole.
The infrared elevator car top spatial operation safety system of embodiment as depicted in figs. 1 and 2, including the thermal infrared human body sensor 10, maintenance relay KV and the elevator master control system that are located at car top 20.Thermal infrared human body sensor includes the first pin 1, the pin 3 of second pin 2 and the 3rd, and the first pin 1 connects 24V voltages, and second pin 2 is grounded.Maintenance relay includes the 4th normally opened contact 44 and the first driving coil 45 of the second normally opened contact 42, the 3rd normally opened contact 43 and the cooperation of the 3rd normally opened contact 43 that the first normally opened contact 41 and the first normally opened contact 41 coordinate.First pin 1 of thermal infrared human body sensor connects the first normally opened contact 41, overhauls the connection elevator master control system of the second normally opened contact 42 of relay KV.3rd pin 3 of thermal infrared human body sensor connects the first coil contact 451 of the first driving coil 45, and the second coil contact 452 of the first driving coil 45 is grounded.When thermal infrared human body sensor senses human body, 3rd pin 3 exports 24V voltages, first driving coil 45 drives the first normally opened contact 41 and the second normally opened contact 42 to connect, elevator master control system receives the maintenance signal (i.e. the input JX voltages of elevator master control system are 24V) that thermal infrared human body sensor sends, then elevator is in maintenance model.Using this structure, thermal infrared human body sensor just senses physical activity when human body is into car top, and elevator enters at once maintenance model, prevents elevator from unexpectedly moving.
The present embodiment also includes the inspection switch DJK and time relay KT for time delay.Inspection switch DJK is ganged switch, including normal open switch 51 and normally closed switch 52.One end of normally closed switch 52 connects the first normally opened contact 41, and the other end of normally closed switch 52 connects the second normally opened contact 42.The time relay includes second normally-closed contact 62 and the second driving coil 63 of the first normally-closed contact 61 and the cooperation of the first normally-closed contact 61.First pin 1 connects the second normally-closed contact 62, and the first normally-closed contact 61 connects the 4th normally opened contact 44, and the 3rd normally opened contact 43 connects the first coil contact 451 of the first driving coil 45.One end of normal open switch 51 of inspection switch DJK connects the second normally-closed contact 62, the other end of normal open switch 51 connection the second driving coil 63 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；The normal open switch 51 of inspection switch disconnects when elevator is in inspecting state, and normally closed switch 52 is closed.
Thermal infrared human body sensor detects car top position whether someone according to body temperature, including the infrared induction source for detecting your optical filter of luxuriant and rich with fragrance mud that ultrared passive type infrared probe and passive type infrared probe coordinate and coordinate with luxuriant and rich with fragrance mud your optical filter.Human body has constant body temperature, and typically at 37 degree, so the infrared ray of specific wavelength 10UM or so can be sent, passive type infrared probe detects the infrared ray of 10UM of human-body emitting or so (i.e. 9UM～11UM) and is operated.The infrared ray of the 10UM of human-body emitting or so is gathered on infrared induction source after luxuriant and rich with fragrance mud that optical filter strengthens.
The other structures of the present embodiment are referring to prior art.
Using the infrared elevator car top spatial operation safety system of the present embodiment, infrared elevator car top spatial operation method for security protection is now illustrated, including：
S1, human body enter car top, the output 24V voltages of 3rd pin 3 when thermal infrared human body sensor senses human body specific wavelength infrared ray (i.e. wavelength is the infrared ray of 9UM～11UM), the voltage of first coil contact 451 of the first driving coil 45 is 24V, first driving coil 45 drives the first normally opened contact 41 and the second normally opened contact 42 to connect, and the 3rd normally opened contact 43 and the 4th normally opened contact 44 connect；Now the input JX of elevator master control system senses 24V voltages, realizes the signal transmission for sending thermal infrared human body sensor to elevator master control system；Now elevator enters and is maintained at maintenance model.
S2, when embodiment one is provided with inspection switch DJK and time relay KT, if the normal open switch 51 of inspection switch DJK is closed, normally closed switch 52 disconnects, after into car top, manual toggle inspection switch DJK realizes that normal open switch 51 disconnects to maintainer, normally closed switch 52 is closed, now time relay KT is not powered on, and the input JX of elevator master control system connects the first pin 1 by normally closed switch 52, and the first normally-closed contact 61 and the second normally-closed contact 62 connect；This structures and methods is realized doing second protection to the safety of human body during maintenance; prevent thermal infrared human body sensor not normal; the input JX voltages that ensure that elevator master control system are O, and active system one directly receives the signal that thermal infrared human body sensor sends, and elevator is in maintenance model.
After S3, maintenance are finished, maintainer stirs inspection switch DJK, realizes that normal open switch 51 is closed, and normally closed switch 52 disconnects, and now time relay KT is powered and starts timing.
S4, maintainer exit car top, and because thermal infrared human body sensor is sensed less than human body, the voltage of the 3rd pin 3 is 0, and the first normally opened contact 41 and the second normally opened contact 42 disconnect, and the 3rd normally opened contact 43 and the 4th normally opened contact 44 disconnect；The voltage of the input JX of elevator master control system is 0, and elevator recovers normal mode.After time relay KT timing reaches preset time value, the first normally-closed contact 61 and the second normally-closed contact 62 disconnect, and easy access personnel withdraw from car top.
The present embodiment is had the advantage that using above structure：
1st, entered without the need for special action before car top using maintainer, once opening, thermal infrared human body sensor senses human body specific wavelength infrared ray to elevator door, and elevator has been put into immediately maintenance model, not there is a possibility that to forget operation.Prevent maintainer from entering after car top, elevator accidental activation causes maintainer's body to be sheared by elevator, really the personal safety of protection maintainer, eliminates safe hidden trouble.
2nd, using inspection switch DJK and time relay KT structures, second protection is done, in maintenance the safety of maintainer is ensure that, while realizing that maintenance model is exited in elevator time delay, beneficial to maintainer car top is exited completely.
The utility model is not limited to above-mentioned embodiment, if to various changes of the present utility model or modification without departing from spirit and scope of the present utility model；If these are changed and modification belongs within the scope of claim of the present utility model and equivalent technologies, then the utility model is also intended to comprising these changes and modification.
