Description

Technical Field

[0001] The invention relates to an energy-saving working system and working method for a washing and sweeping vehicle, belonging to the technical field of washing and sweeping vehicles. Background Art

[0002] The operating modes of existing washing and sweeping vehicles on the market are generally preset into three modes: energy-saving, standard and strong. In these three working modes, the system has specific working parameters of operating devices such as fans and water pumps. In energy-saving mode, the operating device runs at low power and can clean lightly polluted roads containing only dust; in standard mode, the operating device runs at medium power and can clean moderately polluted roads containing dry fallen leaves and smaller stones; in strong mode, the operating device runs at high power and can clean heavily polluted roads containing more wet fallen leaves and larger stones. The driver selects the operating mode according to the actual situation of the road surface. However, in most urban roads, there is a large number of such situations where there is a small amount of dust on the road surface, but there are more fallen leaves and stones in some areas. In this way, the operating mode must be switched frequently, which brings inconvenience to the driver, distracts the driver's attention, and is not conducive to safe driving; or the driver always uses the strong mode to clean the road surface, but this is bound to cause unnecessary energy waste. Summary of the invention

[0003] The purpose of the present invention is to provide an energy-saving working system and working method for a washing and sweeping vehicle, which can achieve energy-saving cleaning effects by adjusting the working mode in real time through detecting the flatness of the road surface.

[0004] In order to achieve the above objectives / solve the above technical problems, the present invention is implemented by adopting the following technical solutions.

[0005] In one aspect, the present invention provides an energy-saving working system for a washing and sweeping vehicle, comprising: a laser transmitter, a camera and a processing unit; The laser emitter is used to emit laser light, and forms a laser belt in real time when the laser light is emitted while cleaning the road surface; The camera is used to obtain a real-time state image of the laser belt on the road surface, and transmit the real-time state image of the laser belt to the processing unit; The processing unit is used to calculate the real-time width of the laser belt, and convert the real-time width of the laser belt into a corresponding work control signal and transmit it to the work control unit of the washing and sweeping vehicle.

[0006] Furthermore, the laser transmitter is installed on the front of the washing and sweeping vehicle; The camera is installed on the front of the washing and sweeping vehicle, the camera is above the laser, and the straight line where the camera and the laser emitter are facing intersects the road surface where the washing and sweeping vehicle is located; The processing unit is integrated inside the cab, one end of which communicates data with the camera, and the other end of which is connected to the washing and sweeping vehicle working control unit to provide corresponding working control signals to the washing and sweeping vehicle working control unit.

[0007] In a second aspect, the present invention provides a method for energy-saving operation of a washing and sweeping vehicle based on the above-mentioned energy-saving operation system of the washing and sweeping vehicle, comprising: Obtain road smoothness data in real time through laser transmitters and cameras; The leveling condition data is transmitted to the processing unit in real time for judgment, and based on the judgment result of whether the road is level, the processing unit sends a corresponding work control signal to the work control unit of the washing and sweeping vehicle to control the operation of the working device.

[0008] Furthermore, the real-time acquisition of road leveling data specifically includes: The laser emitter emits laser to the road surface to be cleaned in real time to form a laser belt. When there are bumps on the road surface, the laser takes a shorter time to reach the road surface, and the laser point on the road surface is closer to the front of the vehicle; when there are potholes on the road surface, the laser takes a longer time to reach the road surface, and the laser point on the road surface is farther away from the front of the vehicle. The total width of the laser belt is always in a fluctuating state according to the different road conditions. The state diagram of the laser belt fluctuating on the road surface is obtained by the camera, and the state diagram of the laser belt is transmitted to the processing unit in real time. The processing unit calculates the preliminary laser belt width through image processing, and can also correct the real-time width of the laser belt through the internal preset database.

[0009] Furthermore, the method for the processing unit to determine the road flatness specifically includes: When the real-time width of the laser band exceeds the set width threshold, the road is deemed to be uneven; When the real-time width of the laser band does not exceed the set width threshold, the road is deemed to be flat.

[0010] Furthermore, when the road is smooth, the washing and sweeping vehicle operation device operates alternately at high and low power at a fixed time, the high power state working time is T, and the low power state working time is t; When the road is detected to be uneven and the washing and sweeping vehicle operation device is running at high power, the high power operation is maintained until the end of the current cycle time T, and then the high and low power operations are alternated; When the road is detected to be uneven and the washing and sweeping vehicle operating device is running at low power, the operating device is switched to high power operation for a running time T, and then alternates between high and low power operation.

[0011] Furthermore, the high-power operation of the washing and sweeping vehicle operation device specifically includes: The washing and sweeping vehicle is in the strong mode, the fan speed of the washing and sweeping vehicle working control unit reaches the rated speed, and the washing and sweeping water pressure is 4~5MPa.

[0012] Furthermore, the low-power operation of the washing and sweeping vehicle operation device specifically includes: The washing and sweeping vehicle is in energy-saving mode, the fan speed of the washing and sweeping vehicle working control unit is lower than the rated speed, and the washing and sweeping water pressure is 3~4MPa.

[0013] Compared with the prior art, the present invention achieves the following beneficial effects: the present invention expands the existing washing and sweeping vehicle operation mode library, improves the existing washing and sweeping vehicle structure at a relatively low cost, and adjusts the operation mode in real time through road surface flatness detection to achieve energy-saving cleaning effects.

[0014] The washing and sweeping vehicle of the present invention does not need to adopt a strong operation mode all the time, and time-sharing control can reduce the average operation energy consumption of the washing and sweeping vehicle; the present invention reduces the driver's intervention in the washing and sweeping operation, allowing the driver to focus on the road traffic conditions, which is safer.
