Abstract
The invention provides an emergency rescue control system with a lifting platform driven by double motors. The emergency rescue control system comprises a control unit, a storage battery in the lifting platform, and a tilt angle sensor, wherein the tilt angle sensor is used for detecting tile angle values of the lifting platform and inputting the tilt angle values to the control unit as analog signals, the control unit converts the analog signals input by the tilt angle sensor to digital signals and then compares the tilt angle values with a parameter value which is preset when the lifting platform is in a horizontal state, after comparison, the control unit respectively outputs different control signals to a motor driving unit a and a motor driving unit b to change driving voltages of an upper rail driving motor and a lower rail driving motor, and therefore the speed of the upper rail driving motor and the speed of the lower rail driving motor are adjusted to achieve tilt adjustment. By means of the emergency rescue control system, a lifting platform horizontal degree adjusting function is achieved in the emergency rescue process; in addition, due to the fact that the storage battery in the lifting platform is used in the system, operation is simpler and more convenient.
Description
Technical field
The present invention relates to the level control field of double-motor, relate in particular to a kind of emergency relief control system of Dual-motors Driving lifting table.
Background technology
Dual-motors Driving lifting table running velocity is fast, power-handling capability is strong, and market is welcome by the user very at home, if but equipment breaks down in operational process, the user will be trapped in the middle of the corridor, and equipment can't run to the safety stop position and save the user.At present, the processing method that generally adopts at this phenomenon is to use storage battery to drive two motor operations from device external, but owing to only can't guarantee two motor synchronous operations with storage battery, thereby cause platform tilt phenomenon to occur, easy damage equipment so not only, and can cause danger to the user, because storage battery itself is relatively heavier, can make rescue operation very inconvenient simultaneously.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective that prior art exists, provide a kind of when the Dual-motors Driving lifting table breaks down, can lightly operate, and can adjust the emergency relief control system of level automatically.
The technical scheme of type of the present invention is: a kind of emergency relief control system of Dual-motors Driving lifting table, it comprises control unit, electric-motor drive unit a, electric-motor drive unit b, the drive motor that gets on the right track, lower railway drive motor, direct supply, also comprise obliquity sensor, described direct supply changes vdc into driving voltage by electric-motor drive unit a and electric-motor drive unit b and outputs to get on the right track drive motor and lower railway drive motor respectively; Described obliquity sensor is worth for detection of the lifting table angle of inclination, and the angle of inclination value inputed to control unit as analog signal, parameter value when control unit is preset with the lifting table horizontality, control unit with the analog signal conversion of obliquity sensor input be after the digital signal during with the lifting table horizontality default parameter value compare, relatively the back control unit is respectively to electric-motor drive unit a and the different control signal of electric-motor drive unit b output, change the driving voltage that electric-motor drive unit a and electric-motor drive unit b output to get on the right track drive motor and lower railway drive motor respectively by different control signals, thereby the speed of regulating get on the right track drive motor and lower railway drive motor realizes tilt adjustments, till parameter value that digital signal value that control unit becomes the analog signal conversion of obliquity sensor input is preset with the lifting table horizontality time is identical.
Described direct supply is the lifting table internal battery.
Described lifting table is Wheelchair Accessible.
The driving voltage of described electric-motor drive unit a and electric-motor drive unit b output is vdc.
The effect of type of the present invention is the function that has reached the adjustment level by the emergency relief control system of Dual-motors Driving lifting table when implementing emergency relief, in the emergency relief process equipment of having guaranteed can run-off the straight situation, therefore improve safety and the stability of equipment in the emergency relief process, also increased traveling comfort simultaneously; Because this system uses is the device interior storage battery, need not to carry outside storage battery in addition, it is simple more, convenient therefore to operate again.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, it comprises control unit 1, obliquity sensor 2, motor control unit a 3, motor control unit b 4, the drive motor 5 that gets on the right track, lower railway drive motor 6, Wheelchair Accessible internal battery 7, and Wheelchair Accessible internal battery 7 changes cell pressure into driving voltage by motor control unit a 3 and electric machine control control unit b 4 and outputs to get on the right track drive motor 5 and lower railway drive motor 6 respectively; The driving voltage of the single a3 of electric machine control and motor control unit b4 output is vdc; Obliquity sensor 2 is worth for detection of the Wheelchair Accessible angle of inclination, and the angle of inclination value inputed to control unit 1 as analog signal, parameter value when control unit 1 is preset with the Wheelchair Accessible horizontality, control unit 1 with the analog signal conversion of obliquity sensor 2 input be after the digital signal during with the Wheelchair Accessible horizontality default parameter value compare, relatively back control unit 1 is exported different control signal with the DA2 port to motor control unit a 3 and motor control unit b 4 by DA1 respectively, change the driving voltage that motor control unit a 3 and motor control unit b 4 output to get on the right track drive motor 5 and lower railway drive motor 6 respectively by different control signals, thereby the speed of regulating get on the right track drive motor 5 and lower railway drive motor 6 realizes tilt adjustments, till parameter value that digital signal value that control unit 1 becomes the analog signal conversion of obliquity sensor input is preset with the Wheelchair Accessible horizontality time is identical.
More than be a kind of embodiment of type of the present invention, a preferred demonstration example.The scope that the present invention asks for protection has more than and is limited to described embodiment.All and technical scheme present embodiment equivalence all belongs to the protection domain of type of the present invention.
