Embodiment Construction
[0040] refer to figure 1 , a main console, used to run programming software, configuration software, and convert various digital and analog commands into control signals and transmit them to two distributed control cabinets through the field bus, and the two distributed control cabinets The transmitted signal calculation is converted into a display signal and sent to the industrial computer for configuration display, and at the same time, the automatic control of the engine speed, traction speed and traction distance is realized according to the logic relationship calculation of each parameter;
[0041] Two sets of sensors, each including engine flywheel sensor, traction wheel sensor and pressure sensor, are used to read various operating parameters of the tractor;
[0042] Two groups of controllers, each group including throttle controller, starter relay and variable amplifier, are used to control the operating parameters of the traction machine read by each group of sensors...

A remote intelligent coordinated control system for tractors comprises a main console, two groups of sensors, two groups of controllers and two distributed control cabinets. The sensors are used for reading the running parameters of tractors. The controllers are used for controlling all tractor running parameters read by both of the two groups of sensors. The control cabinets are used for acquiring the signals of the two groups of sensors, and the signals are converted to required parameters after operation, and transmitted to the main console by a field bus. Meanwhile, control data sent by the main console is read by the field bus, and sent to the two groups of controllers after operated by an automatic control program. The control method makes the tractors have simultaneous traction capability, the revolution speed difference of engines is within 10 revolutions per minute, and the traction distance difference of two tractors is within one meter. Various tractor operations, such as starting, powering off, switching between single tractor and two tractors, controlling engine revolution speed, dragging, controlling wire laying (backing), etc are realized, remote intelligent control is realized, and the problem of two tractors and eight automatic control proposal that wires can not be simultaneously unfolded once for large ton is solved.
Description
technical field [0001] The invention relates to the technical transformation of tractors when the construction plan of two pulls and eight (six) is adopted in the ultra-high voltage construction of power transmission lines, and in particular relates to a remote cooperative control system and control method of tractors. Background technique [0002] With the rapid development of our country's national economy and the increase of transmission capacity of power lines, it is imperative to reduce the economic current density and widely use large cross-section wires. The UHV AC Huainan-Shanghai power transmission and transformation project has prepared to use 8×LGJ-630 / 45 and 8×ACSR-720 / 50 steel-cored aluminum stranded wires. It is also known that the 900mm 2 And above ACSR will also be used in transmission line engineering. According to the traditional one-pulling-multiple scheme, calculate the main traction machine according to the "Code for Construction and Acceptance of ±800k...
