[0005] Furthermore, the method for determining the operating status of the cleaning vehicle comprises the following steps: Step 1: Set the preset speed of the vehicle and the critical value of the speed of the auxiliary engine in the vehicle for driving the cleaning brush, so as to facilitate the subsequent judgment of the operating state of the vehicle according to the preset critical value; Step 2: The cleaning vehicle starts and drives, and the speed detection module is used to collect data on the vehicle's driving speed; It mainly measures linear movements such as acceleration, deceleration, and uphill and downhill movements of vehicles, and can detect rotational movements when turning; Step 3: During driving, the video monitoring module can continuously capture data about the driving status of the vehicle and the road environment around the vehicle through the camera, so that the driver can choose the appropriate cleaning mode according to the degree of dirt on the road; Step 4: The data acquisition module collects the information detected by the speed detection module and the video monitoring module, and transmits it to the data analysis module through the network module to facilitate data preprocessing and analysis; Step 5: The processing module collects data reflecting the vehicle operation status and defines the status according to the data analysis module and the previously preset data; Step 6: The processing module transmits the data of the vehicle operation status that meets the requirements to the status judgment module. At this time, the status judgment module can make a relatively accurate and timely judgment on the vehicle operation status based on the data parameters.
[0006] Furthermore, the data acquisition module, network module, data analysis module, processing module and status judgment module are connected in sequence.

If the vehicle speed is greater than the preset speed threshold, the vehicle is in an overspeed state and is in an invalid working state. Step 3: determining whether the rotation speed of the vehicle auxiliary engine is greater than a preset critical value; If the vehicle speed is less than or equal to a preset speed threshold, determining whether the rotation speed of the vehicle auxiliary engine is greater than a preset threshold; Step 4: Determine whether the vehicle is in normal cleaning state or strong cleaning state; If the speed of the vehicle's auxiliary engine is greater than or equal to a preset critical value, and the water pressure sprayed by the nozzle increases, it is determined that the vehicle is in a strong gear cleaning state; If the rotation speed of the vehicle's auxiliary engine is less than a preset critical value and the water pressure sprayed by the nozzle is normal, it is determined that the vehicle is in a normal cleaning state.
[0008] Furthermore, the data preprocessing can improve the determination efficiency and prevent abnormal values from affecting the determination of the vehicle operating status by subsequent modules.
[0009] Furthermore, a power supply system is provided inside the video surveillance module, and the power supply system is connected to a power supply module of the vehicle, so as to improve the durability of the camera operation.

People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0015] like Figure 1 to Figure 2 As shown, a method for determining the operating status of a sanitation cleaning vehicle in an embodiment of the first aspect of the present invention comprises: a speed detection module, a video monitoring module, a data acquisition module, a network module, a data analysis module, a processing module and a status judgment module, wherein the speed detection module and the video monitoring module are both installed on the cleaning vehicle, the speed detection module comprises a vehicle speed sensor and an acceleration sensor installed in a tire, and the video monitoring module is installed inside and outside the vehicle respectively, the video camera inside the vehicle can monitor the driving status of the vehicle in real time, and the video camera outside the vehicle can monitor the road environment around the vehicle; The parameters collected by the speed detection module and the video monitoring module can be transmitted to the data acquisition module. The data acquisition module can provide real-time data and cache the data to ensure that the entire module system responds quickly. The data acquisition module is responsible for converting analog signals into digital signals and transmitting them to the data analysis module through the network module, so that the data analysis module can process and analyze the acceleration signals, speed signals, driving status of the cleaning vehicle collected by the speed detection module and the video monitoring module, as well as the data parameters of the vehicle driving environment and road environment in the video or image. The processing module is the core of the entire system and is responsible for obtaining data from the above modules and performing calculations; The operation status judgment module is a system component that identifies a specific operation status based on data parameters and a series of pre-set critical values. It can infer the current actual operation status based on the status at a certain moment; At present, the cleaning and sanitation vehicle status can be divided into static operation status, invalid operation status, normal cleaning operation status and strong gear cleaning operation status; The method for determining the operating status of a sanitation cleaning vehicle comprises the following steps: Step 1: Set the preset speed of the vehicle and the critical value of the speed of the auxiliary engine in the vehicle for driving the cleaning brush, so as to facilitate the subsequent judgment of the operating state of the vehicle according to the preset critical value; The auxiliary engine can rotate the cleaning brush to sweep away the dust and garbage on the road. When there is a lot of dirt and garbage on the road, the auxiliary engine can speed up the speed to increase the frequency of the cleaning brush cleaning the road. The side brush sweeps the garbage in the corners of the road from the outside to the inside and concentrates it within the range that the cleaning brush can sweep, which is convenient for quick cleaning of the road. Step 2: The cleaning vehicle starts and drives, and the speed detection module is used to collect data on the vehicle's driving speed; The speed detection module can measure the vehicle's linear movements such as acceleration, deceleration, and uphill and downhill movements during driving, as well as the rotational movements of the vehicle when turning, to improve more accurate and comprehensive vehicle driving detection work; Step 3: During driving, the video monitoring module can continuously capture data about the driving status of the vehicle and the road environment around the vehicle through the camera under the action of the power system, so that the driver can choose the appropriate cleaning mode according to the degree of dirt on the road surface. The height, angle and speed of the cleaning brush can be adjusted according to the mode selection so that it can better contact the dirt on the road surface. At the same time, the position and size of the dust suction port equipped on the cleaning vehicle can be adjusted to more effectively absorb dust and debris; Step 4: The data acquisition module collects the information detected by the speed detection module and the video monitoring module, and transmits it to the data analysis module through the network module to facilitate preprocessing and analysis of the data; Data preprocessing can process data by deletion, identify and process values that deviate from the normal data range, and identify and remove duplicate or unnecessary information to improve judgment efficiency and avoid the above values affecting the subsequent modules' judgment of the vehicle's operating status; Step 5: The processing module collects data and defines the status of the data reflecting the vehicle operation status according to the data analysis module and the previously preset data, and marks the abnormal data parameters of the vehicle and performs further processing; Step 6: The processing module transmits the data of the vehicle operation status that meets the requirements to the status judgment module. At this time, the status judgment module can make a relatively accurate and timely judgment on the vehicle operation status according to the data parameters; If the vehicle speed is 0, the vehicle is in a stationary state; if the vehicle speed is greater than 0, it is determined whether the vehicle speed is less than the preset speed critical value. If the vehicle speed is greater than the preset speed critical value, the vehicle is in an overspeed state and is in an invalid working state; if the vehicle speed is less than or equal to the preset speed critical value, it is determined whether the speed of the vehicle auxiliary engine is greater than the preset critical value; if the speed of the vehicle auxiliary engine is greater than or equal to the preset critical value, and the water pressure sprayed by the nozzle increases, it is determined that the vehicle is in a strong gear cleaning state; if the speed of the vehicle auxiliary engine is less than the preset critical value and the water pressure sprayed by the nozzle is normal, it is determined that the vehicle is in a normal cleaning state.
