Background

Human intelligence promotes social progress, science and technology have permeated daily life silently nowadays, and the intelligent era has come. Garbage cleaning is a laborious task that takes a significant amount of time and effort from the laborer. In order to make the process of cleaning garbage simpler and more convenient, a mechanized tool of a garbage sweeper is provided, and the garbage sweeper can only solve the problem of cleaning efficiency within a certain time, and still has the problems of labor cost, limited working time, high potential safety hazard in the cleaning process, single cleaning mode and the like. The appearance of the automatic driving garbage sweeper changes the current situation of the garbage sweeping market to a certain extent. The integration of a plurality of sensors and a processing system guarantees the safety during operation through systems such as object recognition, distance sensing and quick response, and guarantees the high efficiency of garbage cleaning such as garbage recognition, mode conversion and high-efficiency cleaning. The market of the existing automatic sweeper is still in the sprouting stage, and a plurality of problems are to be solved.

Aiming at the pain points that the existing garbage sweeper is low in intelligentization degree and difficult to clean a garbage can, a disposable environment-friendly garbage bag and an infrared sensor are designed in the garbage can, the garbage can is automatically identified when the garbage can is full, and an operator receiving a prompt only needs to take out the garbage bag for replacement; the introduction of wireless charging technology makes the motor sweeper park the parking stall and charge automatically. On the basis, an automatic garbage sweeper service station is established, parking, automatic charging and garbage collection are integrated, and vehicle operation is standardized and systematized. In the aspect of modeling, the bionic design of bee modeling is integrated, the meaning is diligent and the work is done, and the design of the intelligent automatic driving garbage sweeper which is safe, efficient and attractive is created.

Design investigation and analysis of automatic garbage sweeper

Purpose, meaning and main content of (one) selected subject

With the advent of the intelligent age, machines are replacing humans in more industries and work. Digitalization, networking and intellectualization are prominent features of a new technological revolution and are also the core of a new generation of information technology. The appearance of big data, the Internet of things and the like in recent years enables automobiles to realize the transition from the automatic driving technology to the unmanned driving technology. Unmanned technology has not only benefited the transportation industry, but more industries are exploring cross-border collaboration with unmanned technology.

The sanitation industry is just one of them, and the problem that sanitation work has always existed is that labour demand is big, it is many, road potential safety hazard height to consume time energy, even if driving type garbage sweeper appears, can only solve and clean the efficiency problem, and other problems still exist, for example people can't work well night, daytime physical power is also limited, have traffic hidden danger etc. when driving. The unmanned technology is a good helper for solving the problems. However, people are inexperienced, products are no exception, the number of fingers of the unmanned sweeper which is put into use can be increased, and a lot of places to be improved exist. This design will be based on unmanned motor sweeper technique, through the thought of investigation in earlier stage, pain point excavation, problem solution, designs a safe, high-efficient, pleasing to the eye intelligent automatic driving rubbish motor sweeper of a section, and it is more convenient to make rubbish clean.

(II) investigation and analysis of garbage sweeper products

The garbage sweeper is mature in the market of China, and different products are produced in the market at present and are roughly divided into the following types:

1 sweeping type garbage sweeper: the current market share of the garbage sweeper is the highest, and the garbage sweeper can be divided into the following parts according to the operation mode: heavy-duty driving road sweeper, small-sized driving road sweeper, hand-push type garbage sweeper, unmanned garbage sweeper and the like; according to whether the recyclable garbage is: a pure sweeping type garbage sweeper (only sweeping, no garbage recycling, storing and recycling functions), a storage chamber type garbage sweeper (namely the sweeping machine can recycle garbage), and the like; according to the sprinkling function, the method can be divided into the following steps: garbage sweeper without sprinkling function, dust removal sprinkling type garbage sweeper, pure sprinkling type garbage sweeper and the like.

2, suction type garbage sweeper: because of high technical cost and lower market share than sweeping type garbage sweeper, the sweeping type garbage sweeper can be divided into a pure suction type garbage sweeper, a dry type sweeper, a full suction type garbage sweeper and the like according to different suction and sweeping principles

At present, the market of the garbage sweeper in China is still in a development state, emerging technologies are not popularized, the common sweeping and sucking type garbage sweeper on the market is still simple, the working principle is that garbage is brought into a rear-end garbage inlet through a front-end brush head, the sweeping brush can be driven to run through a rear wheel by utilizing a wheel shaft mechanical principle in the process, then the garbage enters the bottom of the sweeper, the garbage is brought into a garbage bin inlet through a roller, and then the garbage is brought into a garbage storage bin through a suction fan or a conveying device. In addition, most motor sweeper can add the function of watering, can effectively prevent the raise dust. On preventing polluted air, the function of filtering waste gas in the dustbin has still been added to current structure, sends clean air back to the atmosphere.

The market of garbage sweeper in China is rapidly advancing, but has a certain gap compared with the international level, and aiming at the existing products, the following defects and places needing improvement are analyzed:

1, the function is single: the existing garbage sweeper only has the functions of sweeping garbage and sprinkling water.

2 the quality of basic hardware needs to be improved: compared with the hardware quality of the international sweeper, the material quality is low, the material is easy to wear in the using process, and the service life is short. The cleaning force also needs to be greatly improved.

3, complex later maintenance and maintenance: the road condition is complicated, and very easily the loss needs in time to change the part. Most of the mechanical decorations inside need to be lubricated, fastened and replaced in time.

4, energy conservation and environmental protection: most of suction fans at the garbage inlet need engines to provide power, the driving type needs energy sources, and the waste gas emission of garbage and other factors are added, so that the energy-saving and environment-friendly effects are still a problem to be solved. The working principle of the solar sweeper is designed as follows: the solar panel in the energy power part can convert solar energy into electric energy to be stored in the storage battery, and the storage battery supplies power for the motor. However, the conversion rate of converting solar energy into electric energy is low, and the electric energy cannot provide enough electric power for the sweeper and can only be used as auxiliary energy.

5, safety problems: the road is a place with high requirements on safety, vehicles, pedestrians, animals and the like can move freely when the garbage sweeper works, how to not influence the normal functions of the traffic light road during normal work and ensure the safety of the sweeper is one of the problems which still need to be considered at present, and most of the existing garbage sweepers work independently without forming a working mode of a system and obey certain traffic rules and operation specifications like other vehicles.

(III) investigation and analysis of unmanned sweeper

With the emergence of the unmanned technology, more and more related transportation industries are actively introduced with the technology, including freight transportation, passenger transportation, express delivery, construction and other aspects, and the sanitation industry is not behind, and the cooperation with the unmanned technology is started.

The unmanned vehicle has been proposed as early as 30 years ago, but the unmanned vehicle has undergone a long research process to achieve the purpose that the whole driving process is completed by a machine at present, and the unmanned intelligent degrees of different unmanned vehicles are different at present. The starting point of the driverless character is automatic driving, and the driverless character is generally divided into 5 stages from automatic driving to driverless driving:

level 1 is driving assistance, and is only provided with simple lane departure detection, collision prediction and traffic prediction; the 2 nd level is partial automatic driving, the ACC can keep a certain distance and speed with the front vehicle by utilizing the automatic cruise function, and the ACC can automatically brake when sudden braking exists in the front, wherein Tesla is a typical example; the 3 rd level is automatic driving, and can finish the operations of following the vehicle and changing lanes; the 4 th level really realizes unmanned driving, and the intelligent system is changed into the intelligent system full driving from the assistance of a human-body intelligent system, but only an off-line high-precision map can be used for driving under the specified route and scene; and the 5 th level does not need a high-precision map, and can realize all-weather and full-automatic unmanned driving according to the perception of the self system to the surrounding environment.

Currently, the 5 th level, i.e. the highest level of unmanned driving, is realized, which of course needs to be realized through a plurality of sensors and a large amount of digital information, and the process is roughly divided into the following 5 levels: the system comprises a sensor layer, a driving layer, an information fusion layer, a decision planning layer and a bottom control layer.

The sensor layer consists of a plurality of sensors arranged in the vehicle, and comprises an ultrasonic sensor and a distance measuring sensor on the side part and a millimeter wave radar sensor in the front of the vehicle;

the driving layer is a layer for processing the sensor information, and it needs to analyze the information such as the pictures, numbers, etc., and for example, coordinate transformation is performed on the sensor information in each direction, and the coordinate transformation is similar to X, Y, Z axes in mathematics. The data is processed and transmitted to the next level;

the information fusion layer is a hierarchy for fusing sensor information, for example, three sensors in three directions of the vehicle are all distinguished from the same pedestrian, the information fusion function is to integrate the sensors into one pedestrian, and the information fusion layer is not three pedestrians;

the decision planning layer carries out final decision and planning on the work after information integration;

the bottom control layer finally realizes one step of operation, such as finishing actions of driving, steering, braking, backing, sweeping and the like.

At present, products for introducing the unmanned technology into garbage cleaning work are few, the products are still in a preliminary exploration stage at present, recently, 3 types of unmanned garbage cleaning vehicles such as a cool garbage cleaning vehicle, a fairy-way intelligent vehicle and a snail-shaped white vehicle begin to enter the visual field of people, and the three products have different functional characteristics and appearances.

The cruel-Java unmanned garbage sweeper is mainly focused on cleaning of five parks including a park, a community, a factory and an exhibition hall airport, the appearance structure of the piloting type garbage sweeper is still kept at present, and although the significance of keeping a cockpit lies in manual operation under the convenient emergency, the appearance is still heavy and deceptive. What is focused on by kuwa is the automation of the garbage cleaning work, such as automatic detection of road surface garbage, automatic selection of different cleaning modes, automatic planning of an optimal cleaning route, and the like.

The intelligent unmanned sweeper in the fairway is divided into a large sweeper and a small sweeper, the large sweeper is concentrated on urban roads, expressways and overhead sweeping work, the small sweeper is concentrated on scenic spots, parks and non-motor vehicle lanes, and the appearance of the driving type garbage sweeper is kept. The immortal way intelligence firstly overcomes the problem that buildings and trees shield GPS positioning, and an SLAM mode is integrated into an original GPS positioning system. At present, the first intelligent cleaning motorcade in the fairway is trying to operate.

The snail-whitish unmanned sweeper has been put into a plurality of cities for use and becomes a street star, the concept of the snail is utilized, the garbage sweeper runs slowly due to the complex system and the safety of operation, the moral meaning of slow running of the snail is utilized, the shape is smooth and lovely like a snail, the snail-whitish unmanned sweeper becomes a bright scenic line on the road, and pedestrians walking the snail-whitish and loves the snail.

Research and analysis on market of garbage sweeper

1 environmental sanitation industry transformation period

In recent years, the development of the environmental sanitation industry is catalyzed by the inclination of national policies and the current situation of garbage increment, along with the increasing of urbanization, the ground cleaning area of China is increased rapidly, people have higher requirements on the quality of the environment, and the discrepancy is that the old generation of environmental sanitation workers are about to leave the post along with the coming of aging of the population. The growth environment of the young generation is relatively superior due to different concepts, and the realization of self value is pursued more, so the environmental sanitation industry faces the problem of lack of manpower because people are willing to do less due to the characteristics of environmental sanitation work fatigue, low wages, poor environment and the like. Secondly, with the development of society, the mechanization intelligence is more and more developed, and the labor cost is higher. These difficulties push the transposition industry to the way of mechanization and intelligence.

2007-2014 urban road sweeping area and mechanized sweeping area coverage area change

Due to the fact that governments pay attention to environmental sanitation work in recent years, a series of policies support the development of environmental sanitation mechanization, and by 2015, the average value of the mechanized cleaning rate of domestic cities is as high as 55%, the average value of the mechanized cleaning rate of the domestic cities is 43% in county cities, and the mechanized cleaning rate of the domestic cities is increasing year by year. The unmanned sweeper can fundamentally solve the problems of human resources and cleaning efficiency, an unmanned mechanical cleaning revolution is coming, license plates are provided for the unmanned sweeper in a plurality of domestic cities nowadays, the license plates are successfully researched and developed to be put into use, mass production is realized, and the unmanned sweeper is not far away when going to the market.

2 analysis of market feasibility of unmanned garbage sweeper

The unmanned garbage sweeper not only uses the unmanned technology on the garbage sweeper, but also better helps to complete garbage sweeping work through an intelligent system in the unmanned technology.

From the safety perspective, no matter the traditional cleaning work is operated by pure manual work or manual driving, certain potential safety hazard problems exist, and people can not timely perceive and react to surrounding conditions. "according to the relevant studies, the perception error accounts for approximately 53%, the decision error for 38%, and the operation error and other causes for 9% of the total traffic accidents. ". The potential safety hazard is high when cleaner or driving type motor sweeper work, if avoid the peak period of driving in daytime, work also can be very painstaking night or in the morning, and fatigue state work has bigger hidden danger. Most of the current cleaners are middle-aged and old people, and the body perception and the reaction force are reduced along with the aging of the body, so that the cleaners are more dangerous. If the machine can completely replace human driving, the potential safety hazard in the cleaning process is probably greatly reduced. The advantages are numerous in addition to this.

From a value point of view, the overall cleaning efficiency can be improved. The unmanned technology ensures that the garbage cleaning process is more standard, can clean garbage for all weather, long time and high force, overcomes the defects of limited manual working time and limited physical strength, and saves the manpower management cost.

From the economic point of view, the long-term development will save a great deal of cost. The cost of an unmanned sweeper is 30-40 ten thousand yuan at present, the unmanned sweeper can work for 20-24 hours a day, the annual salary of a cleaner is 6-8 ten thousand, the unmanned sweeper can only work for 6-8 hours a day, the sweeping efficiency of the sweeper is equivalent to 3 persons, the purchase cost of the unmanned sweeper can be recovered after 2 years, and then the sweeping work can be continued at the cost of 0. Moreover, at present, with the development of mechanized intelligence, the labor cost becomes high, and software and hardware will gradually become low along with the development cost of the industry, so that higher economic benefits can be obtained.

From the perspective of social environment, government policy and regulations are more and more open, license plates of unmanned garbage sweeper vehicles are distributed in many cities at present, and even products such as snail-shaped white are introduced and used in many provinces later. The cooperation of each industry and the unmanned technology starts to be developed following the era pace, so that the automation of more and more industries is realized, and the environmental sanitation industry is changed from mechanization to intellectualization.
