Description
Technical field
The utility model relates to a kind of elevator control gear, particularly a kind of elevator that can prevent dry running.
Background technology
Now commercially use elevator, mostly there is the shortcoming of the low and wasting of resources of operating efficiency that elevator dry running causes.According to statistics, the consumption of current of elevator accounts for 20%-30% of entire building, but elevator ubiquity people is the problem that maloperation or mischief cause elevator dry running now, namely elevator interior calling or external call button operation descendant have left, cause elevator dry running under immunization with gD DNA vaccine, this shortcoming not only reduces the operating efficiency of elevator, and wastes a large amount of electric power resource.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to propose a kind of elevator that can prevent dry running, the no-load ratio of elevator can be reduced, improve the operating efficiency of elevator, reach the object preventing elevator dry running, have that long service life, operating efficiency are high, the feature of energy saving.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of elevator that can prevent dry running, comprise servomotor 1, servomotor 1 is electrically connected with the signal output part of master controller 3, servomotor 1 is connected with lift car 2 top by assembly pulley, pressure sensor 4 is installed bottom lift car 2, pressure sensor 4 is electrically connected with the signal input port of master controller 3, lift car 2 inside is provided with annunciator 5, annunciator 5 is electrically connected with the signal output port of master controller 3, top, elevator doorway is provided with microwave human detection switch 6, microwave human induction switch 6 is electrically connected with the signal input port of master controller 3.
Because the utility model have employed pressure sensor and microwave human detection switch, when pressure sensor detects the inner non-loaded or load weight of lift car lower than set lower limit, lift car Internal call was lost efficacy, unmannedly etc. after microwave human detection switch detects elevator external call to bide one's time, then external call was lost efficacy, compared to the elevator in currently available technology, effectively can prevent the elevator dry running that user causes the maloperation of elevator or mischief operation, the no-load ratio that elevator can be run reduces by 20%, improve the operating efficiency of elevator, extend the service life of elevator, the consumption of current of elevator can be reduced about 20% simultaneously, save a large amount of electric power resource at raising elevator operating efficiency simultaneously.

Fig. 3 is workflow diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, Fig. 2, a kind of elevator that can prevent dry running, comprise servomotor 1, servomotor 1 is electrically connected with the signal output part of master controller 3, servomotor 1 is connected with lift car 2 top by assembly pulley, pressure sensor 4 is installed bottom lift car 2, pressure sensor 4 is electrically connected with the signal input port of master controller 3, for detecting the condition of loading in elevator, lift car 2 inside is provided with annunciator 5, annunciator 5 is electrically connected with the signal output port of master controller 3, top, elevator doorway is provided with microwave human detection switch 6, microwave human induction switch 6 is electrically connected with the signal input port of master controller 3, for elevator doorway after detecting external call, whether someone continues to wait for.
Described master controller 3 adopts the PLC of mitsubishi FX2N-48MR-001 model as elevator main controller, and this PLC is relay output type, and can drive direct current 30V or exchange 25V load, it inputs output point number of counting and is 24 points.PLC have highly versatile, easy to use, adapt to wide, reliability is high, antijamming capability is strong, the feature such as simple of programming, its high reliability can process each incoming signal efficiently, in real time, comprise the signal of pressure sensor collection and the signal of human body microwave inductive switch collection, and control the execution components and parts of corresponding output end.
The pressure signal collected is inputed to the signal input port of master controller 3 by described pressure sensor 4, process collection signal by master controller 3 and judge force value whether in setting range, when detected pressures scope, in setting range, elevator interior calling is normal runs; When pressure sensor 4 detected pressures is lower than setting range lower limit, Internal call was lost efficacy, and elevator does not run; When pressure sensor 4 detected pressures is higher than setting range higher limit, Internal call was lost efficacy, and elevator does not run, and annunciator 5 starts to report to the police simultaneously.
Described microwave human induction switch 6 adopts KG001-220V-M, it is the automatic control sensor based on microwave technology, have highly sensitive, reliability is high, the feature of intelligent, hommization, adopt the input of 220V alternating current, setting height(from bottom) 2.5m-3.5m, detection angle is 360 °, detecting distance is maximum reaches 10m, detecting distance can regulate from switch as required, when detecting that there is people on elevator doorway, elevator external input signal is effective, when accurate measurement to elevator outside nobody etc. bide one's time, elevator external call was lost efficacy, and elevator does not run.
See Fig. 3, principle of work of the present utility model is:
By controlling master controller 3, pre-setting elevator interior load weight value range is 20kg-1800kg, and this range set value can adjust according to elevator use occasion and elevator power.When pressure sensor 4 detects that lift car 2 internal load weight is in set scope, effectively, elevator normally runs in lift car 2 Internal call operation; When pressure sensor 4 detect lift car 2 internal load weight be zero or load weight lower than set lower limit 20kg time, elevator is left after being judged as people's maloperation, then lift car 2 Internal call operation failure, does not respond lift car 2 Internal call; When pressure sensor 4 detects that lift car 2 internal load weight exceedes set higher limit 1800kg, be judged as elevator overload, then lift car 2 Internal call operation failure, elevator interior sends overload warning simultaneously.
When microwave human induction switch 6 detects that elevator doorway has people to wait, microwave human induction switch 6 outputs signal to master controller 3, and master controller 3 judges that this layer of external call panel operation is effective, and elevator runs so far floor and to stop enabling; If after this layer of external call panel has call operation, but microwave human detection switch 6 detects that elevator doorway is unmanned etc. bides one's time, then this layer of external call operation failure, elevator can not stop at this floor.
