Abstract
The invention discloses an automatic centering method of an elevating fire truck rotary table, and belongs to the technical field of forming equipment. The automatic centering method mainly comprises the steps that when the rotary table is in an automatic truck closing state, the current deflection state of the rotary table relative to the middle position is automatically judged through a fire truck, therefore, the rotary table moves towards the centering position in the radial direction by automatically selecting a rotary path closest to the middle position, the current deflection position is known in real time through a bus type absolute encoder in the moving process, the rotary table slows down to do rotating movement at a proper centering deflection position till the rotary table is completely centered, and the process is controlled to be finished. The automatic centering method has the advantages of being precise in centering, and free of manual centering and saving time and labor.
Description
Technical field
The present invention relates to former technical field, be specially a kind of elevating fire truck turntable automatic centering method.
Background technology
Elevate the electric intelligence control system of fire-fighting equipment and adopt original-pack German IFM mechanically moving equipped with dedicated control device, the each functional action of elevating fire truck is effectively controlled, improve the reliability of fire-fighting equipment, make to elevate fire-fighting equipment to march toward intelligent automaticization, improve car load level of digital; The application of standardized CAN communication bussing technique, improves real-time, the reliability of the transmission of electrical system data acquisition process; In addition, interference free performance improves greatly; CAN interfacing adopts, and also provides interface for realizing remote wireless monitoring, and also communicate with control unit of engine ECU to by J1939 agreement, direct exchange of control information provides convenient effective passage simultaneously.
Elevate the electric intelligence control system of fire-fighting equipment and comprise existing 25M and the 18M vehicle of company, although vehicle is different, the controller model of employing is different, and have employed identical control technology and control method, this control technology and method have adaptability widely; The functional control elevating the electric intelligence control system of fire-fighting equipment mainly comprises: automatic leveling, automatically exhibition return the vehicle to the garage and knock off, automatic/hand centering, action wired remote control, getting-on-off interlocking and action spacing etc.
Summary of the invention
The present invention for the technical problem that solves for providing a kind of elevating fire truck turntable automatic centering method, its can the current fire fighting truck turntable of automatic decision relative to the deflection state in centre position, the automatic selection rotary road radial alignment position the shortest from centre position is moved, current deviation position can be understood by bus type absolute encoder in real time in moving process, and to be rotated in deceleration movement at suitable centering deviation position, until entirely on the center.
Technical solution problem of the present invention adopts following technical scheme:
A kind of elevating fire truck turntable automatic centering method is provided, be mainly turntable under the condition of automatically returning the vehicle to the garage and knock off, the current deflection state relative to centre position of fire fighting truck automatic decision turntable, thus automatically select the rotary road radial alignment position the shortest from centre position to move, current deviation position is understood by bus type absolute encoder in real time in moving process, and to be rotated in deceleration movement at suitable centering deviation position, until entirely on the center, this control procedure terminates, its spy be it comprise following some:
(1) elevating fire truck is under condition of automatically returning the vehicle to the garage and knock off, and by start button, automatic centering function is opened;
(2) according to revolving table position automatic rotation centering, when relative centering angle is greater than 180 °, turntable anticlockwise is 0 ° of end to relative angle, and when relative centering angle=180 °, turntable right rotation is 0 ° of end to relative angle;
(3) in turntable automatic centering process, as once rotated centering failure, then will return and proceed centering adjustment, until turntable centering is terminated;
(4) after centering is terminated, elevating fire truck centering indicator lamp is lighted, and fire fighting truck proceeds to pack up operation to jib.
The present invention compared with prior art, its beneficial effect is: its can the current fire fighting truck turntable of automatic decision relative to the deflection state in centre position, the automatic selection rotary road radial alignment position the shortest from centre position is moved, current deviation position can be understood by bus type absolute encoder in real time in moving process, and to be rotated in deceleration movement at suitable centering deviation position, until entirely on the center, centering is accurate, without the need to centering manually, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of a kind of elevating fire truck turntable of the present invention automatic centering method.
Detailed description of the invention
The technological means realized to make the present invention, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
A kind of elevating fire truck turntable automatic centering method, be mainly turntable under the condition of automatically returning the vehicle to the garage and knock off, the current deflection state relative to centre position of fire fighting truck automatic decision turntable, thus automatically select the rotary road radial alignment position the shortest from centre position to move, in moving process, understand current deviation position by bus type absolute encoder in real time, and to be rotated in deceleration movement at suitable centering deviation position, until entirely on the center, this control procedure terminates, it comprise following some:
(1) elevating fire truck is under condition of automatically returning the vehicle to the garage and knock off, and by start button, automatic centering function is opened;
(2) according to revolving table position automatic rotation centering, when relative centering angle is greater than 180 °, turntable anticlockwise is 0 ° of end to relative angle, and when relative centering angle=180 °, turntable right rotation is 0 ° of end to relative angle;
(3) in turntable automatic centering process, as once rotated centering failure, then will return and proceed centering adjustment, until turntable centering is terminated;
(4) after centering is terminated, elevating fire truck centering indicator lamp is lighted, and fire fighting truck proceeds to pack up operation to jib.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
