Abstract
The utility model provides an automatic positioning system for a refrigerator door. The automatic positioning system for the refrigerator door comprises a refrigerator door opening machine which is connected with a motor, an encoder capable of feeding back pulse numbers is installed on the rear portion of the motor and connected with a central controller, and transmission and feedback of data can be achieved between a control system and the central controller. The automatic positioning system for the refrigerator door does not need a limiting switch, saves cost and avoids inconvenience of installation, and by means of setting several parameters, a segment speed position of the refrigerator door opening machine can be controlled, the operation is simple, and the modification is convenient.
Description
Technical field
The positioning control of the utility model design cold-storage door relates in particular to a kind of automatic station-keeping system that is used for cold-storage door.
Background technology
In present cold-storage door control system, employing be that limit switch is installed on the guide rail, meet first travel switch during the operation of motor switch door and quicken; Run into second switch and quicken again, run into the 3rd switch and slow down, run into the 4th switch and slow down again; Running into the 5th switch stops; This mode will be installed five limit switches or more, change the position and must move limit switch again, and fault rate is high.
The utility model content
The utility model provides a kind of automatic station-keeping system that is used for cold-storage door, and the method through reasonable and simple motor combines with encoder greatly reduces cost, and control accuracy is high.
The purpose of the utility model realizes through following technical scheme:
A kind of automatic station-keeping system that is used for cold-storage door; Comprise the cold store door lifter; Said cold store door lifter links to each other with motor; The rear of said motor is equipped with the encoder with feedback pulse number, and encoder and central controller are through carrying out the transmission feedback of data between control system and the central controller.
Preferably, be provided with corresponding 7 sections speed position according to the different pulse number on the said cold store door lifter.
Compared with prior art, the advantage of the technical scheme of the utility model is:
1, do not need limit switch, saved cost and inconvenient installation.
2, only, just can arrive any requirement of client through pressing the parameter of the corresponding umber of pulse of several sections speed of key assignments, simple to operate, it is convenient to revise.And the parameter of setting can forever be preserved.
Description of drawings
Fig. 1 is the structural representation that is used for the automatic station-keeping system of cold-storage door of the present invention.
Label declaration among the figure: 1 is the cold store door, and 2 is encoder, and 3 is motor; 4. one section fast position of the switch family status, 5. two sections fast positions of the switch family status, 6. three sections fast positions of the switch family status; 7. four sections fast positions of the switch family status; 8. five sections fast positions of the switch family status, 9. six sections fast positions of the switch family status, 10. seven sections fast positions of the switch family status.
The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Embodiment 1
In conjunction with shown in Figure 1; A kind of system that is used for the automatic station-keeping system of cold-storage door of the present invention; Comprise cold store door 1, said cold store door links to each other with motor 3, and the rear of motor 3 is equipped with the encoder 2 with feedback pulse number; Said encoder 2 is connected with central controller, through carrying out the transmission feedback of data between control system and the central controller.
According to the different pulse number, on said cold store door 1, be provided with the fast position in six sections of the fast positions in five sections of the fast positions in four sections of the fast positions in three sections of the fast positions in two sections of the fast positions of one section of the switch family status 4, the switch family status 5, the switch family status 6, the switch family status 7, the switch family status 8, the switch family status 9,10 these corresponding 7 sections speed positions, seven sections fast positions of the switch family status successively.
Control principle: native system adopts encoder to carry out the control of speed, and encoder 2 is installed in the rear of motor 3, utilizes motor rotor to drive encoder; When motor moves, utilize rotor rotation, thereby make encoder 2 produce a pulsed quantity; The control system reads in this pulsed quantity in the central controller again; According to the automatic run switch door of the umber of pulse of encoder feedback multistage curve, such as moving first section speed at closing time, second section speed of operation when CPU counts umber of pulse 300;, CPU moves the 3rd section speed when counting umber of pulse 700 ... the rest may be inferred.CPU converts umber of pulse to position signalling, realizes accurate location with this.The user only needs on controller, to set the shift position and the rotating speed of each section, and controller generates smoothed curve according to the rate of change of position and speed automatically, thereby greatly reduces cost, and control accuracy is high.
The foregoing description is technical conceive and the characteristics for the utility model is described just, its objective is to be the content that lets the one of ordinary skilled in the art can understand the utility model and to implement according to this, can not limit the protection domain of the utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the utility model.
Claims (2)
