Shared vehicles have assumed more tasks for medium and long distance trips during the duration of a public health event, and become one of the main commuting tools. According to big data of Meichun, the usage amount of the Shenzhen bicycle is increased by 49% and the riding distance is increased by 60% after the Shenzhen double-production double-work. According to the measurement and calculation of data released by the department of transportation and the national information center, the user scale of two rounds of shared trips in China in 2020 can reach 2.87 hundred million people, and the user scale is increased by 10.8% on a year-by-year basis. According to the statistical data display of the national information center, the national shared single-vehicle market scale is continuously improved in 2017. By 2020, the nationwide shared single car market size is about 220 billion dollars. Shared bicycles have become an important component of the transportation industry in China.

According to the research at present, the pneumonia transmission routes of the novel coronavirus infection which can be determined at present are mainly direct transmission, aerosol transmission and contact transmission. Contact transmission refers to the deposition of droplets on the surface of an article, and the contact of the droplets with the hand of a person who comes into contact with a pollution source and then with the mucous membranes of the mouth, the nasal cavity, the eyes and the like, thereby causing infection. Compared with public transportation modes such as buses and subways, the bicycle has better ventilation effect and longer social distance when going out, reduces the possibility of aerosol transmission, but is easier to cause contact transmission at the position of the handle contacted by the palm due to the sharing property.

Detailed Description

The following describes a specific embodiment of the present invention with reference to the accompanying drawings and technical solutions.

As shown in FIG. 1, an automated decontamination system for a shared bicycle includes a power module and an acquisition execution module; the power module mainly comprises a pressure air bag 1, a one-way gas valve 2, an atomizing nozzle 3, a gas pipe 4, a liquid conveying pipe 5, a pneumatic chamber 7, a one-way gas-liquid valve 10, a hydraulic chamber 11, a hose filter hole 14 and a disinfectant replenishment hole 15. Contain among the collection execution module, pressure sensor 9, pressure sensor 12, integrated chip 8 and voice broadcast ware 6.

One side of the pressure air bag 1 is connected with the outside through a one-way air valve 2; the other side of the pressure air bag 1 is connected with an air delivery pipe 4; the air delivery pipe 4 and the infusion pipe 5 are in a nested relation. The air pipe 4 is communicated with the air pressure chamber 7. The infusion tube 5 is communicated with the hydraulic chamber 11, passes through the air pressure chamber 7, the pressure air bag 1 and the hydraulic chamber 11 and is connected with the atomizing nozzle 3; the one-way gas valve 2 only allows outside gas to enter the pressure air bag 1 and prevents the gas of the pressure air bag 1 from flowing out of the one-way valve; the air delivery pipe 4 and the infusion pipe 5 connected with the pressure air bag 1 and other shared bicycle brake cables are arranged in the hollow framework of the shared bicycle together. A user can press the pressure air bag 1 for a plurality of times to pressurize the air pressure chamber 7, the pressure of the air pressure chamber 7 is increased, and gas enters the hydraulic chamber 11 through the gas-liquid one-way valve 10 to further pressurize the hydraulic chamber 11; the pressure air bag 1 is made of a resilient rubber material and can automatically restore to an original shape after being extruded. The pressure air bag 1 is used as a power source of the system, the size of the pressure air bag is close to that of a palm, and the pressure air bag is arranged at the neck of the head of the sharing bicycle.

The shapes of the air pressure chamber 7 and the hydraulic pressure chamber 11 are approximate to 2-3 cubic decimeters of plastic square boxes. The pneumatic chamber 7 and the hydraulic chamber 11 are installed on a keel of the shared bicycle. The hydraulic chamber 11 and the air pressure chamber 7 are in a nested structure. The bottom of the air pressure chamber 7 is connected with a one-way gas-liquid valve 10; the one-way gas-liquid valve 10 only allows air in the pneumatic chamber 7 to enter the hydraulic chamber 11, and prevents disinfectant in the hydraulic chamber 11 from entering the pneumatic chamber 7; the gas transmission pipe 4 and the liquid transmission pipe 5 are respectively connected with the hydraulic chamber 11 and the air pressure chamber 7 through the hollow framework; the air pressure chamber 7 is a place for isolating air and liquid; the hydraulic chamber 11 is a place for storing disinfectant; in order to store as much disinfectant as possible in the hydraulic chamber 11, the volume of the pneumatic chamber 7 can be reduced as much as possible in consideration of the manufacturing difficulty, the manufacturing cost, the volume of the gas-liquid check valve 10 and the volume of the pressure sensor 9.

The acquisition execution module comprises: pressure sensor 9, pressure sensor 12, integrated chip 8 and voice broadcast ware 6. The pressure sensor 9 is located inside the air pressure chamber 7. The pressure sensor 12 is located inside the hydraulic chamber 11; the integrated chip 8 with the voice broadcast ware 6 is located among the intelligent lock. Each part in the acquisition execution module carries out wireless transmission through Bluetooth signals.

As shown in fig. 1, the implementation process of the power module is as follows:

the user squeezes the pressure air bag 1 several times, and the gas enters the air pressure chamber 7 through the gas transmission pipe 4. When the air pressure in the air pressure chamber 7 is large enough, the air enters the hydraulic chamber 11 through the air-liquid one-way valve 9. Since the gas density is much less than the liquid density. Air is collected at the upper side of the hydraulic chamber 11 while the pressure of the hydraulic chamber 11 is continuously increased.

When the pressure sensor 12 detects that the pressure of the hydraulic chamber 11 reaches the rated spraying pressure, the integrated chip 8 sends an opening instruction to the electric switch 13. The electronic switch 13 is turned on, and the disinfectant in the hydraulic chamber 11 passes through the spray head through the infusion tube 5 to disinfect the handlebar and the basket.

After timing and sterilizing for 30 seconds, the integrated chip 8 sends a switch closing instruction to the electric switch 13. And (5) finishing the disinfection.

As shown in fig. 2, the pneumatic chamber 7 and the hydraulic chamber 11 are arranged at the shared bicycle keel; the gas pipe 4 and the infusion pipe 5 are arranged in the hollow framework in a concealed mode and are connected with the air pressure chamber 7, the hydraulic chamber 11, the pressure air bag 11 and the atomizing nozzle 3; the pressure air bag 1 is arranged at the neck part of the handlebar; the atomizer 3 is mounted on the handlebar.

As shown in fig. 3. The nozzle 31 is fixed on the handlebar in a ring structure and is used for disinfecting the handlebar in all directions. The spray head 32 is installed at the head of the vehicle to sterilize the basket.

As shown in fig. 4, the implementation process of the acquisition execution module is as follows:

the integrated chip 8 in the vehicle lock continuously detects the state of the vehicle lock. When the lock state is in the locking state, the system starts to time to judge whether the user can not finish the disinfection.

When pressing 1 time of pressure gasbag is less than 3 minutes, voice broadcast ware 6 sends out instruction one: please press the pressure air bag at the handlebar in time to finish the disinfection, otherwise, the vehicle returning fails. "then the pressure sensor 12 detects whether the pressure in the hydraulic chamber 11 is greater than the rated spray pressure. If not, returning to judge whether the pressing time is less than 3 minutes. If reach rated spray pressure, the voice broadcast ware sends suggestion instruction two: you have successfully finished locking the car, please leave in time, and start to disinfect after 10 seconds. After the instruction is sent for two 10 seconds, the electronic switch is turned on, and the disinfectant is sprayed out from the atomizing nozzle to disinfect the key parts. And after the electronic switch is turned on for 30 seconds, the electronic switch is turned off. And (5) finishing the disinfection.

When the pressure air bag 1 is pressed for more than 3 minutes, the system judges that the user can not finish disinfection and starts an emergency scheme I: firstly, a user is reminded to finish disinfection in time by a mobile phone APP or a short message sent to the user. And secondly, if the user still does not disinfect, the system locks the shared bicycle, stops using the shared bicycle, and calls workers to disinfect and unlock the bicycle through the network.

As the amount of sterilant decreases, the pressure at the pressure sensor 12 decreases under non-use conditions. When the pressure decreases to the preset pressure threshold value, the pressure sensor 12 sends a signal for replenishing the disinfectant to the integrated chip 8. The integrated chip 8 calls staff to replenish the disinfectant through the network. When the user maliciously presses the pressure air bag 1 continuously, the pressure sensor 9 detects that the pressure is continuously increased for a long time, transmits a signal to the APP, and penalizes or claims compensation for the user.
