Closing thus elevator will cause harm to the human body, and existing elevator often needs to repair elevator or maintenance work, therefore
The safety for improving car top and pit is necessary, it is therefore necessary to be improved.
Summary of the invention
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of elevator human body sensing safety
Protective device, there are the personnel for preventing from entering car top and pit not press emergency stop switch by regulation to cause personal injury same for it
When do not influence the characteristics of car top personnel are to elevator maintenance repair.
To achieve the goals above, the technical scheme adopted by the utility model is a kind of elevator human body sensing is protected safely
Protection unit, including lift car, control module and elevator operating control device further include car top apparatus for detecting human body, pit people
Body detection device, car top control device, pit control device and warning device, the car top control device includes parallel with one another
Car top overhauling key and car top relay；The pit control device includes pit confirmation key and pit relay parallel with one another
Device, the car top control device, pit control device and elevator operating control device series connection, car top apparatus for detecting human body position
It is located at lift car pit, the car top apparatus for detecting human body, bottom in top, the pit apparatus for detecting human body outside lift car
Hole apparatus for detecting human body, car top relay, pit relay are connected by conducting wire with control module with warning device.
Further, the warning device includes buzzer and LED light.
Further, the car top apparatus for detecting human body and pit apparatus for detecting human body are all made of pyroelectric human body infrared sense
Inductive switch.
Further, the pit confirmation key is reset button.
After adopting the above structure, the utility model is compared to the prior art advantageously: the application can prevent into
Enter the personnel of car top and pit and do not press emergency stop switch by regulation to cause personal injury, wherein car top control device, pit
Control device and elevator operating control device series connection, only in car top and pit all no ones or car top someone but press sedan-chair in this way
Elevator could operate normally more safe in the case that top overhauls key or pit someone but presses pit confirmation key；
Wherein car top apparatus for detecting human body, pit apparatus for detecting human body, car top relay, pit relay and warning device pass through conducting wire
It is connected with control module, the signal that such car top apparatus for detecting human body and pit apparatus for detecting human body will test passes through at signal
Electronic feedback is managed to control module, then control module control car top relay driving module control car top relay or pit after
Electrical equipment drive module controls the work of pit relay, and warning device work is controlled when detecting someone, plays a warning role, mentions
Awake operator presses car top overhauling key or pit confirmation key.Wherein pit confirmation key is that reset button works as operator
Elevator is mobile when confirming key according to pit, and when operator does not press pit confirmation key, elevator is automatically stopped work, this
Sample avoids operator from forgetting that cancelling pit confirmation key causes elevator to be constantly in moving condition, more safety and circuit is more
What is added is simple.
Detailed description of the invention
Fig. 1 is the local circuit schematic diagram of the utility model.
Fig. 2 is the system module figure of the utility model.
Fig. 3 is the position view of the utility model car top apparatus for detecting human body and pit apparatus for detecting human body.
Specific embodiment
As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model
It encloses, the present invention will be further described with reference to the accompanying drawings and examples.
Embodiment, as shown in Fig. 1 to Fig. 2: a kind of elevator human body sensing safety guard, including lift car 10, control
Molding block and elevator operating control device, wherein control module includes control chip P1, it is characterised in that: further includes car top human body
Detection device K1, pit apparatus for detecting human body K2, car top control device, pit control device and warning device, wherein car top control
Device processed includes car top overhauling key SW1 and car top relay J1 parallel with one another；Wherein car top overhauling key SW1 is also in series with
Control module D1 is overhauled, control module D1 job control elevator is overhauled when pressing car top overhauling key SW1 in this way and makes accordingly
Movement；Wherein pit control device includes pit confirmation key SW2 and pit relay J2 parallel with one another, wherein car top control
Device, pit control device and elevator operating control device D2 series connection processed, as someone in car top, car top relay J1 is disconnected in this way
It opens, elevator operating control device D2 controls elevator operation contactor if car top overhauling key SW1 is not also pressed at this time
Coil circuit disconnects prevent elevator avoids causing people injured or bottom with raw touch of the human hair in car top from normally starting operation
Pit relay J2 is disconnected when someone in cheating, and elevator motion control fills if pit confirmation key SW2 is not pressed at this time
