DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. 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.

[0022] At present, the reflective rings in tunnels are usually cleaned manually on site. This method usually requires closing the road to clean the reflective rings and the cost of manual cleaning is too high. Based on this, a reflective ring cleaning device and system provided in this embodiment can realize digital cleaning of reflective rings and reduce the problem of high cost of manual cleaning.

[0023] To facilitate understanding of this embodiment, a reflective ring cleaning device disclosed in an embodiment of the present invention is first introduced in detail.

[0024] Embodiment 1

[0025] A reflective ring cleaning device includes a motion module, a control module and a communication module; Figure 1 As shown, the motion module includes a trolley unit, a pumping unit, a cleaning unit and a guide rail assembly; the guide rail assembly includes a guide rail 1 and a guide rail bracket 2, the guide rail 1 is installed on the wall of the tunnel through the guide rail bracket 2, and the guide rail extends along the length direction of the reflective ring and is parallel to the reflective ring; the trolley unit includes a vehicle body 3, a support wheel 4 and a driving wheel 5 arranged on the vehicle body, a driving motor 6 for driving the driving wheel 5, and a slider 7 arranged on the vehicle body and located on both sides of the driving wheel 5; a guide groove (not shown in the figure) is opened on the inner side of the slider. A guide ball 8 protruding from the guide groove is provided in the guide groove; the trolley unit is hung upside down on the guide rail 1 through the slider 7 and the guide ball 8, and the driving wheel 5 is in contact with the guide rail 1; one end of the support wheel 4 is supported on the wall 12 of the tunnel, and a nut 9 is provided on the other end of the support wheel 4 and installed on the vehicle body 3, and the nut 9 is used to adjust the distance between the vehicle body and the wall 12; the cleaning unit includes a cleaning brush 10 and a rotating motor 11, and the cleaning brush 10 is connected to the rotating motor 11, and the rotating motor 11 provides rotational kinetic energy for the cleaning brush 10;

[0026] The control module is electrically connected to the drive motor, the water pump, the rotating motor and the communication module respectively.

[0027] In this embodiment, the control module controls the motion module by implementing a wireless LAN or wired operation mode through the communication module. The trolley unit in the motion module is hung upside down on the guide rail through a slider and a guide ball, and is used to transport the pumping unit and the cleaning unit to the reflective ring to clean the reflective ring; the height distance between the car body and the wall is controlled by the support wheel. By adjusting the nut on the support wheel, the distance between the car body and the wall is adjusted, so that the cleaning brush can better clean the reflective ring on the wall. In addition, the trolley is designed with a card slot to ensure that the trolley fits tightly with the guide rail to prevent the trolley from slipping. Since the trolley only needs to reciprocate on the track, there are only two movement directions of the trolley body: forward and backward. By adjusting the movement direction of the drive motor, the movement direction of the trolley can be changed. Since the kinetic energy of the trolley body is mainly provided by the friction between the drive wheel and the guide rail, the speed of the drive wheel will determine the movement speed of the trolley. At the same time, the trolley is set to three speeds, which are 10 rpm, 20 rpm and 50 rpm respectively. Different gears determine the speed of the trolley, which corresponds to the needs in different situations. For example, if you choose a high speed gear in daily situations, you can clean the dust on the surface of the reflective ring in a short time. At this time, you can increase the strength of the cleaning brush to ensure the cleaning effect.

[0028] It should be noted that the guide rail installed on the tunnel wall is a detachable guide rail. When the reflective ring needs to be cleaned, the guide rail can be installed on the wall of the tunnel along the guide rail bracket. The guide rail can be removed after the motion module trolley has cleaned the reflector. Prevent the guide rail from being air-dried and increase the service life of the guide rail. The rotating motor that drives the cleaning brush, the water pump that pumps water out of the water tank, and the drive motor that drives the vehicle body to move are all connected to the control module circuit through the communication module to achieve control requirements. The communication method used in the communication module is mainly through the two communication methods of WIFI communication unit and GPRS communication unit to realize the wired or wireless operation mode between the device and the module, and between the modules.

[0029] In this embodiment, the reflective ring cleaning device also includes a power module, which is electrically connected to the control module, the drive motor, the water pump, the rotating motor and the communication module respectively to provide sufficient power for all drive devices to ensure the normal operation of the equipment.

[0030] It should be noted that due to the operation of multiple motors, the device of the present invention also has high requirements for power supply. For example, the power supply of the driving trolley is intended to adopt a 12V / 50Ah rechargeable lithium battery solution, and two solutions are designed: a removable battery solution, after the battery power is exhausted, the operator can go to the site to replace the battery with a fully charged battery; the on-site charging solution is to set a charging position on site, and when the trolley power is about to be exhausted, the trolley automatically drives to the charging position and starts charging through the charging program to realize the automatic charging function. Considering that the trolley is working at full load, the working current is 1A, then the trolley can work continuously for 50 hours. If the trolley works for 2 hours a day, it can work continuously for 25 days without battery replacement or charging, which greatly reduces the labor cost. The power supply voltage of the power supply of the rotating motor is designed to be 12V, and the power supply of the rotating motor is directly powered by a lithium battery pack. The current is specifically adjusted according to the rotation speed of the cleaning brush; the power supply voltage of the water pump power supply is designed to be 12V, and the water pump can be directly powered by a lithium battery pack. Choose a low-power water pump with an expected working current of less than 0.3A and power less than 3W to increase the battery working time.

[0031] The structural diagram of the pumping unit is as follows Figure 2 As shown, the pumping unit includes a water tank 13, a water pump 14 and an atomizing nozzle 15. The water tank is arranged on the vehicle body, the water pump 14 is connected to the water tank 13 through a pipe 16, and the atomizing nozzle 15 is arranged at the cleaning brush, and the atomizing nozzle 15 is connected to the water pump 14 through a pipe 16. However, the connection structure of the pumping unit is not limited to Figure 2 The connection method uses an atomizing nozzle at the water spray outlet to increase the wetting area of ​​the reflective ring and reduce the amount of water that falls and drips on passing vehicles due to a large amount of water spray.

[0032] It should be noted that the water tank capacity designed by the present invention is 1 to 5L, and the water tank capacity can also be adjusted according to different needs. In this embodiment, the maximum capacity of the water tank cannot exceed 5L, otherwise it exceeds the carrying capacity of the trolley. Excessive water tank capacity will also bring safety hazards to passing vehicles. In order to facilitate water replenishment, the water tank can also be designed as a detachable water tank and a self-replenishing water tank. Among them, the detachable water tank is replaced by the operator after the water is exhausted, and the empty water tank is pumped out and replaced with a water tank filled with water. Or on the premise that there is a water source on site, when the water is exhausted, the trolley will go to the water replenishment position by itself, and the automatic water replenishment function is realized through the cooperation of the program and the sensor.

[0033] In addition, the height of the support wheel can be adjusted by adjusting the nut, and the guide rail is used as a fulcrum to form a lever to adjust the strength of the cleaning brush. The height of the support wheel is controlled by adjusting the nut. As the height of the support wheel increases, the right side drops due to the lever principle, making the cleaning brush fit more closely, thereby achieving the adjustment of the strength of the cleaning brush. The adjustment of the support wheel height nut is controlled by the control module and can be set by the operator.

[0034] like Figure 3 As shown, in this embodiment, the control module also includes a processor 17, a sensor module 18, a power supply unit 19 and a display 20. The sensor module 18 is electrically connected to the processor 17 via a serial bus interface. The sensor module transmits the collected target signal to the processor for processing. The display is electrically connected to the processor via an SPI serial bus interface and receives the target signal. The power supply unit provides power to the control module.

[0035] The connection mode of the above-mentioned serial bus interface also includes the connection mode of I2C serial interface and UART serial interface, but is not limited to the connection mode of the above-mentioned two serial interfaces, and a more reasonable or convenient serial interface connection mode can be selected according to actual application. The processor adopts STM32 chip as the main control, communicates with the mobile terminal through the Wi-Fi communication module, and controls the car through the mobile terminal.

[0036] It should be noted that in order to monitor the remaining power and water volume of the vehicle, this embodiment also includes a power sensor and a water level sensor, which are electrically connected to the STM32 chip respectively. The power sensor is used to monitor the remaining power of the first power supply, and the water level sensor is used to monitor the remaining water volume in the water tank.

[0037] In order to better ensure the normal operation of the trolley body, setting a power sensor to detect the remaining power of the trolley body is a better means to control whether it can continue to work. Otherwise, without knowing the remaining power of the trolley, it is difficult to judge whether the trolley does not work due to external faults or insufficient power. In this embodiment, a cumulative flow valve is used to estimate the remaining power. This estimation method has the advantages of accurate estimation of the remaining power and low overhead. In order to ensure that the water tank can continuously supply water, the remaining water volume of the water tank is monitored by setting a water level sensor, and it is judged whether it is sufficient to complete the next reflective ring cleaning work according to the monitoring data. It should be noted that during the operation, the position of the water in the water tank is constantly changing, so it is impossible to monitor the remaining water volume during the operation process. The remaining water volume in the water tank can only be estimated when it is not in operation and in a horizontal state. In order to ensure the measurement effect and filter the influence of gravity on the liquid level during the movement of the trolley, an ultrasonic water level sensor is used to measure the position of the water in the water tank during the non-working time of the trolley. At the same time, in order to better monitor the temperature, humidity and dust concentration of the environment in which the reflective rings in the tunnel are located, so as to perform cleaning operations on the reflective rings, temperature and humidity sensors and dust concentration sensors can be added to the trolley body or guide rails.

[0038] The processor analyzes the power sensor value, water level sensor value, temperature and humidity sensor value, and dust concentration sensor value detected by the sensor module, and transmits the analysis results to the display for display. The staff determines whether it is necessary to issue a cleaning instruction for the reflective ring of the car body based on the results displayed on the display.

[0039] In this embodiment, the control module also includes a storage device, and the storage device is used to store the target signal processed by the processor. Usually, when the storage device performs the storage function, it will combine automatic backup and manual backup. Automatic backup is a scheduled backup, and the scheduled time is set by certain parameters; manual backup means that the operator can back up all the data at that time at any time. Regardless of the backup method, after the data is backed up, the backup file name is the start and end date of the data, and the operator can store the data on a CD as a data file. The storage device mainly uses an optical disk drive, and the capacity of a CD can reach 9.1GB, which requires manual disk replacement.

[0040] Embodiment 2:

[0041] In view of the technical problem that cleaners usually drive cleaning vehicles to the tunnel site to clean the reflective rings, which causes obstruction to road traffic, this embodiment provides a reflective ring cleaning system, such as Figure 4As shown, the reflective ring cleaning system 21 includes a cloud server 22, a central control room 23 and a mobile terminal 24. The built-in control module of the mobile terminal controls the movement of the motion module through a wireless local area network. The mobile terminal communicates with the cloud server through a built-in communication module and performs data analysis. The cloud server then transmits the result of the data analysis to the central control room through the communication module. The staff determines whether it is necessary to issue an instruction to the operator to clean the reflective ring based on the result of the data analysis displayed on the screen of the central control room.

[0042] Here the operation of the entire system is divided into two modes for detailed explanation.

[0043] One mode is the manual mode, which requires workers to operate at the construction site (i.e., the tunnel) and use a mobile terminal to control the trolley to complete operations such as moving forward, backward, and wiping the reflective ring. After setting the cleaning brush speed, trolley running speed, and cleaning brush strength, the automatic scrubbing of the reflective ring can be performed automatically. The trolley automatically stops operating after completing a cycle, and the scrubbing work can also be manually terminated during automatic operation. When stubborn stains are found, manual control is used to move the trolley to the specified position through the forward and backward operation buttons, and then the target position is specially scrubbed. After the trolley cleaning work is completed, the mobile terminal will automatically upload information such as the remaining power and water volume of the trolley to the storage device of the processor.

[0044] The other mode is the automatic mode. Workers do not need to go to the construction site for on-site operations. They only need to use web pages or PC software to remotely access the system in the control room, office or control center to view and manage the status of all trolleys connected to the system in each tunnel. They can also accurately access a specified trolley and view the status of physical quantities such as the battery level and water level of the trolley.

[0045] It should be noted that the wireless local area network includes but is not limited to wireless network communication technologies such as WIFI communication units or Bluetooth. Similarly, the public communication module also includes but is not limited to GPRS, 3G, 4G, 5G (and including the 6G that will appear in the future) communication technologies.

[0046] However, the advantage of Wi-Fi communication unit over other wireless communication methods lies in its high-speed transmission efficiency. And it is easy to increase its transmission power (using ESP8266 Wi-Fi module, with 10dbm transmission power and omnidirectional antenna, the packet loss rate within 300 meters is only 1%. When using directional antenna, the communication distance can be increased to kilometers.) to increase its transmission distance in the tunnel. It is planned to adopt Wi-Fi P2P, an important technical specification newly launched by the WI-FI Alliance, with the trade name Wi-Fi Direct. It supports multiple Wi-Fi devices to connect to each other without AP (Access Point). In the case of a long tunnel with multiple reflective rings, two adjacent reflective rings can realize network self-organization through the Wi-Fi Direct protocol. Operators do not need to go to multiple reflective rings, but can operate in one location. The mobile terminal is equipped with a GPRS device and can communicate directly with the cloud server. After connecting to the car's Wi-Fi, the mobile terminal will automatically read the sensor data stored in the car, upload the data to the cloud server for data analysis, and transmit the results of the data analysis to the central control room. The staff in the central control room can display the results on the central control room screen, understand the environment of each tunnel and the surface cleaning of the reflective ring, analyze and manage it, and determine whether it is necessary to issue reflective ring cleaning instructions to the operator.

[0047] It should be noted that the transmission methods include GPRS communication and WIFI communication units, but are not limited to these two transmission methods. For example, Bluetooth devices with similar functions to WIFI communication units can also realize wireless transmission methods; similarly, 3G, 4G and 5G (including 6G that will appear in the future) with similar functions to GPRS communicate with the cloud central control room. The cloud server mainly uses computer terminals to query, remind and analyze relevant data such as car bodies, tunnel reflective rings, maintenance staff, etc. The system can use Windows 2000Server as the operating platform, and use the Microsoft SQL Server 2000 database, a large-scale relational network database that is also a product of Microsoft and runs in a microcomputer environment. Since Microsoft SQL Server 2000 provides a powerful data query function, you can not only query the data in the data table directly, but also create views based on the table according to requirements. Through the view, you can shield the specific structure of the table and set different authority ranges for operators. According to the various types of users, such as ordinary employees, employee group leaders, general managers or managers, multiple user types are set for this purpose, and user authority is divided, with basic functions such as adding, deleting and modifying. Its authority table is shown in Table 1.

[0048] Table 1 User authority table

[0049] Field Name type width Decimal Keywords User ID CHARACTER 10 yes username CHARACTER 8 no password CHARACTER 10 no User Group CHARACTER 10 no

[0050] When storing data, in addition to automatic scheduled backup, it should also be combined with the operator to be able to back up all the data at any time. In order to prevent the system from failing and failing to store data, it can also be stored through manual storage as a remedial measure. Regardless of the backup method, after the data is backed up, the backup file name is the start and end date of the data, and the operator can store the data on a CD as a data file. The storage device mainly uses an optical disk drive to store the target data related values ​​collected by the STM32 processor. At the same time, the system also sets a reminder function to remind the administrator to clean the tunnel reflective ring. Cleaning mainly adopts two methods: one is to remind according to the maintenance time requirements; the other is to remind according to the collected particle concentration in the tunnel air (install relevant sensors in the tunnel for collection), to achieve complete intelligent and refined management.
