The invention relates to the technical field of equipment control and particularly relates to a controller, a concrete transport vehicle and a temperature monitoring method. The controller comprises an oil temperature monitoring module, a high-temperature early warning module and a mixing drum rotating speed control module, wherein the oil temperature monitoring module is used for monitoring whether the collected oil temperature of a hydraulic oil tank exceeds a preset oil temperature threshold value or not in real time, and carrying out air cooling of the hydraulic oil tank if the collected oil temperature exceeds the preset oil temperature threshold value, the high-temperature early warning module is used for sending out the high-temperature early warning information for the hydraulic oil tank if the oil temperature of the hydraulic oil tank is still in a rising state within the preset time, and the mixing drum rotating speed control module is used for determining a displacement adjustment value under the current oil temperature of the hydraulic oil tank according to an acquired displacement value of a driving pump and adjusting the displacement of the driving pump based on the displacement adjustment value so as to change the rotating speed of a concrete mixing drum. The controller is advantaged in that the oil temperature of the hydraulic oil tank of the mixing drum can beeffectively monitored in real time, so accuracy of the control time of the mixing drum can be effectively improved according to the oil temperature monitoring result.
Description
technical field [0001] The present application relates to the technical field of equipment control, in particular, to a controller, a concrete transport vehicle and a temperature monitoring method. Background technique [0002] Cement concrete mixing is widely used in industrial, agricultural, transportation, national defense, water conservancy, municipal and other construction projects, and the demand is constantly increasing. Concrete mixing equipment is also constantly innovating and progressing, and the technical level is gradually improving. Concrete mixing is divided into manual mixing and mechanical mixing. Among them, the concrete mixer truck in mechanical mixing is a special truck used to transport concrete for construction; because of its shape, it is often called a snail truck. These trucks are equipped with cylindrical mixing drums to carry the mixed concrete. During transportation, the mixing drum will always be kept rotating to ensure that the carried concret...
