Description
Technical field
The invention belongs to elevator overload detection technique field, particularly judge the detection technique of elevator overload based on space occupancy, relate to a kind of lift space overload detector of detecting based on infrared dot matrix and method.
Background technology
Along with society and the development in city, the hommization of lift facility, safe and low energy consumption etc. have become the development tendency in this field, and the energy shock of growing tension brings new requirement to the energy-conservation of elevator further.
Traditional elevator overload detects mainly Weighing type and detects, namely pass the load signal of coming by pressure sensor to judge, the defect of the method is to have taken envelope (as empty carton when object, the objects such as table stool), but when weight does not arrive limit, can't judge that elevator is in overload condition, the increase of elevator waiting time and elevator motor start-stop number of times will be caused like this.Actual conditions show, the energy consumption that the start-stop of motor consumes accounts for the 30%-50% of the overall energy consumption of elevator, and therefore the minimizing motor start-stop number of times of science has positive meaning for raising elevator operating efficiency.In addition, the minimizing start-stop number of times of science can improve the comfort of passenger, greatly strengthens the intelligent level of elevator.
Therefore, be badly in need of a kind of method of inspection for lift space overload at present, reach with this and reduce the object that energy consumption improves occupant comfort sense.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of lift space overload detector of detecting based on infrared dot matrix and method, the method and device may be used for detecting when elevator weight does not also overload, but elevator overload situation when now the space of envelope is occupied full.
For achieving the above object, the invention provides following technical scheme:
Based on the lift space overload detecting method that infrared dot matrix detects, comprise the following steps: step one: in the space of elevator, set up the infrared dot matrix in space, this dot matrix comprises infrared launcher and receiving device; Step 2: start infrared dot matrix and carry out work, convert space hold information to electric signal; Step 3: electric signal is processed, computer memory Occupation efficiency; Step 4: whether overload in space to judge elevator, realizes the control to elevator according to judged result.
Further, in step one, in elevator during the infrared dot matrix of installation space, be uniformly distributed according to lift space size, infrared launcher is arranged on elevator top, and infrared receiving device is arranged on bottom elevator.
Further, in step 2, when infrared point battle array works, infrared launcher and corresponding infrared receiving device form one and accept detection circuit, if this bundle infrared ray arrives a receiving device smoothly, the electric signal that then can produce certain strength as this receiving device of infrared optical sensor exports, and namely control system is judged as normal circumstances; If this bundle infrared ray is blocked by the body, then corresponding receiving device no signal exports; Control system controls all infrared launchers and launches infrared beam successively in order, judge the Received signal strength output intensity of a corresponding infrared receiving device in order successively simultaneously, scan round, form one space infrared acquisition light curtain, and convert lift space occupied information to electric signal.
Present invention also offers a kind of lift space overload detector detected based on infrared dot matrix, this device comprises the infrared dot matrix in the space be made up of infrared launcher and infrared receiving device, signal processing unit, signal output unit, central controller and elevator controlling loop; The infrared dot matrix in space converts lift space occupied information to electric signal, and electric signal is sent to signal processing unit, process for central controller after A/D conversion, computer memory Occupation efficiency, whether overload in space to judge elevator, thus controlled elevator by elevator controlling loop.
Further, the infrared dot matrix in described space is installed in lift space, is uniformly distributed according to lift space size, and infrared launcher is arranged on elevator top, and infrared receiving device is arranged on bottom elevator; When infrared point battle array works, infrared launcher and corresponding infrared receiving device form one and accept detection circuit, if this bundle infrared ray arrives a receiving device smoothly, the electric signal that then can produce certain strength as this receiving device of infrared optical sensor exports, and namely control system is judged as normal circumstances; If this bundle infrared ray is blocked by the body, then corresponding receiving device no signal exports; Control system controls all infrared launchers and launches infrared beam successively in order, judge the Received signal strength output intensity of a corresponding infrared receiving device in order successively simultaneously, scan round, form space infrared acquisition light curtain, and convert lift space occupied information to electric signal, by judging space occupancy rate and then realizing the intelligentized control method of elevator.
Beneficial effect of the present invention is: method and apparatus of the present invention may be used for detecting when elevator weight does not also overload, elevator overload situation when but now the space of envelope is occupied full, the start-stop of elevator can be made more accurately rationally, elevator operation energy consumption be can significantly reduce simultaneously, operating efficiency and the intelligent level of elevator greatly improved.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the invention provides following accompanying drawing and being described:
Fig. 1 is the diagram of circuit of the method for the invention;
Fig. 2 is the infrared dot matrix schematic diagram in space.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
Fig. 1 is the diagram of circuit of the method for the invention, as shown in the figure, the lift space overload detecting method detected based on infrared dot matrix of the present invention comprises the following steps: step one: in the space of elevator, set up the infrared dot matrix in space, this dot matrix comprises infrared launcher and receiving device; Step 2: start infrared dot matrix and carry out work, convert space hold information to electric signal; Step 3: electric signal is processed, computer memory Occupation efficiency; Step 4: whether overload in space to judge elevator, realizes the control to elevator according to judged result.
Specifically:
