Including 3D imaging sensor and PLC controller, 3D imaging sensor install on the top of the car shop front to lift -cabin door one side, 3D imaging sensor is connected with PLC controller electricity, the PLC controller respectively with the car door quick -witted and elevator lift/lower electromechanics be connected. The advantage: through the 3D imaging sensor extension protection to elevator car entry door zone, expand sensor monitoring range to car and the outer floor ground of lift -cabin door, can monitor whether parallel and level of car and floor ground, eliminate the potential safety hazard, perfect the door zone protection of car, have the interior number statistics function of car, can avoid the unnecessary stop of car when the car is at full strength, improve elevator dispatching efficiency, overall structure is simple, simple to operate.
Description
Technical field
This utility model belongs to car safety and controls technical field, is specifically related to a kind of cabin elevator door district entrance and monitors protection system.
Background technology
At present, existing most of cabin elevators use light curtain to protect sensor, light curtain to need to be arranged on both sides, car doorway as elevator door, carry out multiple spot plane correlation, are only just considered as someone when barrier blocks correlation luminous point and pass in and out；Also need to configure single-point correlation level transducer at hoistway simultaneously, the barrier blocking luminous point is installed at the anchor point of each floor, guarantees when car is stopped concordant with floor ground with this.In above-mentioned existing scheme, need two set sensors to cooperate and could normally work, control complexity, installing complexity, cost is high, and any a set of sensor goes wrong or mistake occurs in control program, it is likely to make because of combination miss elevator out of control, thus causes immeasurable consequence.From security risk, level transducer is combined with light curtain, improve the reliability of elevator dispatching, will be the trend of the times of technology development.
It addition, existing cage operation there is also following problems: such as car manned the fullest in the case of, if there being people to press the operation button outside car, car still can regular calling, elevator dispatching efficiency is low；Efficiency is pursued by modern society, and people are the most in a hurry to depart, is arranged on the light curtain of both sides, car doorway, only barrier and arrives appointment region, car doorway, just can determine whether, for there being people to pass in and out, easily to cause the event of crushing, there is great potential safety hazard.
In view of above-mentioned prior art, the applicant has made useful design, and technical scheme described below produces under this background.
Summary of the invention
The purpose of this utility model is to provide a kind of cabin elevator door district entrance to monitor protection system, and simple in construction is easy for installation, is provided that the monitoring and protecting that car entrance region is complete.
The purpose of this utility model is such to reach; a kind of cabin elevator door district entrance monitors protection system; it is characterized in that: include 3D imaging sensor and PLC; described 3D imaging sensor is arranged on the car door top towards elevator door side; 3D imaging sensor electrically connects with PLC, PLC respectively with car door machine and elevator lifting mechatronics.
In a specific embodiment of the present utility model, described 3D imaging sensor includes the microprocessor with tally function.
In another specific embodiment of the present utility model, described 3D imaging sensor also includes camera array.
This utility model is owing to have employed said structure; compared with prior art; have the beneficial effect that and extend the protection to lift car entrance door district by 3D imaging sensor; by the floor ground outside sensor monitoring expanded range to car and elevator door; car can be monitored the most concordant with floor ground; eliminate safe hidden trouble, improve the door district protection of car；There is demographics function in car, the stop that car is unnecessary can be avoided when car is full, improve elevator dispatching efficiency；Overall structure is simple, easy for installation.

Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail by applicant by combining accompanying drawing below; but applicant is not the restriction to technical scheme to the description of embodiment, any changing in the form rather than substance according to this utility model design all should be considered as protection domain of the present utility model.
Embodiment 1:
Refer to Fig. 1, Fig. 2 and Fig. 5; this utility model relates to a kind of cabin elevator door district entrance and monitors protection system; including 3D imaging sensor 1 and PLC 2; described 3D imaging sensor 1 is arranged on the car door 3 top towards elevator door 4 side, and described PLC 2 is arranged in the switch board of elevator controlling room.3D imaging sensor 1 electrically connects with PLC 2, PLC 2 respectively with car door machine and elevator lifting mechatronics.Described car door machine is for controlling the open and close of car door；Described elevator hoisting machine is for controlling the ascending, descending of car, stopping.In the present embodiment, described 3D imaging sensor 1 uses the TOFgard/Mini that auspicious electricity scholar (Changshu) sensor company limited produces, it forms an obstacle monitored area 5 in lift car entrance door district, utilize 3D stereo technology monitoring car the most concordant with floor ground and monitor doorway obstacle, the event that crushes caused because monitoring by mistake can be prevented effectively from, improve the safety in utilization of elevator.The low and high level of reaction monitoring signal is exported to PLC 2 by 3D imaging sensor 1, PLC 2 realize the control to car door machine and elevator hoisting machine.
Embodiment 2:
Refer to Fig. 3 and Fig. 5, described 3D imaging sensor 1 also includes the microprocessor with tally function, in the present embodiment, described 3D imaging sensor 1 uses the TOFgard/Counting that auspicious electricity scholar (Changshu) sensor company limited produces, and described microprocessor is the dsp chip that Texas Instrument produces.Described 3D imaging sensor 1 forms a carrying monitored area 6 in car, by microprocessor, the seating capacity in car is added up, if it is the most full in car, then control elevator hoisting machine by PLC 2, make motor elevator not stop in respective storey further according to the instruction of car door machine, thus can improve the dispatching efficiency of elevator.
Embodiment 3:
Refer to Fig. 4 and Fig. 5, described 3D imaging sensor 1 also includes camera array, in the present embodiment, 3D imaging sensor 1 uses the TOFgard/3D that auspicious electricity scholar (Changshu) sensor company limited produces, it expands the monitoring range of obstacle monitored area 5, barrier mobile monitoring region 7 is formed in the outside (away from the side of car) of obstacle monitored area 5, camera array is utilized to judge barrier in car entrance region, the i.e. moving direction of people, distinguish barrier move towards elevator or pass by elevator, when car door to be ready closing, without breaking the barriers, arrival appointment region, doorway just can judge to be to continue with closing the door or stop to close the door, can be more effectively prevented from crushing event to occur by mistake, improve elevator safety in utilization and work efficiency.
