Technical Field
[0001] The present application relates to the technical field of cleaning equipment, and in particular to a remote communication box for monitoring cleaning equipment. Background Art
[0002] Cleaning equipment is a mechanical device used to replace manual cleaning work. It can effectively reduce the labor cost of cleaning work and improve work efficiency. It is widely used in shopping malls, airports, libraries, museums, hotels, etc. As the market competition for cleaning equipment continues to intensify, the cost of equipment operation and maintenance continues to rise, and at the same time, we have to face the loss caused by idle production capacity, which requires the requirements of real-time online monitoring equipment.
[0003] At present, the existing remote communication box (Internet of Things module) for monitoring cleaning equipment usually borrows the positioning monitoring module of the car and uses GPS for positioning, which can achieve global all-weather positioning with high accuracy and fast real-time positioning speed.
[0004] However, the above-mentioned related technologies have the following problems: when the cleaning equipment is located indoors, due to the weak penetration of the satellite signal, it is difficult for the receiver of the cleaning equipment to accurately calculate the propagation time and distance of the satellite signal. Therefore, indoors, the existing remote communication box for monitoring the cleaning equipment is difficult to obtain the exact location of the cleaning equipment. Utility Model Content
[0005] In order to address the deficiencies in the prior art, the present application provides a remote communication box for monitoring cleaning equipment, which can improve the accuracy of indoor and outdoor location information while also obtaining the status of the cleaning equipment to minimize malfunctions.
[0006] The present application provides a remote communication box for monitoring cleaning equipment using the following technical solution:
[0007] A remote communication box for monitoring cleaning equipment includes a satellite positioning unit, a communication positioning unit, a data acquisition unit and a CPU for integrating location information and equipment data and sending execution commands. The satellite positioning unit, the communication positioning unit, the data acquisition unit and the CPU are electrically connected.
[0008] By adopting the above technical solution, the satellite positioning unit can quickly obtain high-precision location information outdoors when acquiring the location information of the cleaning equipment. However, due to the weak penetration of the satellite signal, it is difficult for the satellite positioning unit to receive it indoors. When the satellite positioning unit receives the satellite signal well, the satellite positioning unit acquires the location information. When the satellite positioning unit cannot receive the satellite signal, the CPU sends an execution command to enable the communication positioning unit to acquire the location information, and then upload the location information to the server, thereby improving the accuracy of acquiring location information indoors and outdoors. The data acquisition unit can acquire the status data of the cleaning equipment, and the user can understand whether the current cleaning equipment is working normally based on the status data to avoid malfunctions as much as possible.
[0009] The present application further provides that: the communication positioning unit includes a 4G module, the 4G module is electrically connected to the satellite positioning unit, and the 4G module is electrically connected to the CPU.
[0010] By adopting the above technical solution, the 4G network has a wide signal coverage and can provide continuous positioning services indoors. When the satellite positioning unit cannot receive the satellite signal, the CPU cannot receive the location information from the satellite positioning unit and sends an execution command to enable the 4G module to obtain the location information, thereby increasing the way to obtain location information indoors and improving the accuracy of obtaining indoor location information.
[0011] The present application further provides that: the communication positioning unit also includes a WIFI module, and the WIFI module is electrically connected to the CPU.
[0012] By adopting the above technical solution, the WIFI module uses the wireless LAN signal for indoor positioning. The wireless LAN signal has strong penetration, so it is not easy to lose the location information during indoor positioning. When the 4G module does not receive the 4G signal, the CPU cannot receive the location information from the 4G module and sends an execution command to enable the WIFI module to obtain the location information, thereby increasing the ways to obtain the location information and improving the accuracy of the obtained location information.
[0013] The present application further provides that: the CPU is electrically connected to an RFID module for locating the floor number, and the RFID module is electrically connected to the communication positioning unit.
[0014] By adopting the above technical solution, when the RFID module scans the radio frequency card installed on the floor, it can obtain the floor number where the current cleaning equipment is located, thereby improving the accuracy of obtaining the location information of the cleaning equipment indoors and outdoors.
[0015] The present application further provides that: the data acquisition unit includes a current acquisition module and a status acquisition module, the current acquisition module is electrically connected to the CPU, and the status acquisition module is provided with a lithium battery information interface and a CAN interface for receiving device status.
[0016] By adopting the above technical solution, the current acquisition module can collect the charging and discharging current of the battery when the cleaning equipment uses a lead-acid battery to obtain the battery power and status. The lithium battery information interface can obtain the battery information of the lithium battery. The CAN interface is used to connect to the controller of the cleaning equipment and obtain the status of various motors. The CPU integrates the information collected by the battery acquisition module and the status acquisition module. When a fault occurs, the root cause of the current fault can be reflected.
[0017] The present application further provides that: the CPU is electrically connected to a Flash storage module.
[0018] By adopting the above technical solution, the Flash storage module is used to store the acquired location information and device data when the communication positioning unit has no signal, and re-upload the location information and device data to the server when the communication positioning unit acquires the signal, so as to avoid the loss of location information and device data due to not being uploaded to the server.
[0019] The present application further provides that: the CPU is electrically connected to a power management module, and the power management module is electrically connected to a satellite positioning unit, a communication positioning unit, a data acquisition unit, an RFID module, and a Flash storage module.
[0020] By adopting the above technical solution, the power management module is responsible for managing the power of each unit and each module. When not working for a long time, each unit and each module can be put into a dormant state to reduce battery consumption and avoid battery over-discharge as much as possible.
[0021] The present application further provides that: the lithium battery information interface is an RS232 interface.
[0022] By adopting the above technical solution, the RS232 interface is used to connect the BMS board of the lithium battery in the cleaning equipment to monitor and protect the circuit board of the lithium-ion battery.
[0023] In summary, this application has the following beneficial effects:
[0024] In the present application, when the satellite positioning unit receives satellite signals well, the satellite positioning unit obtains the location information. When the satellite positioning unit cannot receive satellite signals, the CPU sends an execution command to enable the communication positioning unit to obtain the location information, and then upload the location information to the server. Multiple methods of obtaining location information make it difficult to lose the location information, thereby improving the accuracy of obtaining location information indoors and outdoors. The data acquisition unit can obtain the status data of the cleaning equipment. The status data of the cleaning equipment can reflect whether the current cleaning equipment is working normally, thereby reducing the possibility of failure. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figures 1 to 4 This application is described in further detail.
[0031] refer to Figure 1 and Figure 2In this embodiment, a remote communication box for monitoring cleaning equipment includes a satellite positioning unit 1, a communication positioning unit 2, a data acquisition unit 3 and a CPU4. The satellite positioning unit 1 is electrically connected to the CPU4 through a serial port, and the communication positioning unit 2, the data acquisition unit 3 and the CPU4 are electrically connected. The CPU4 is used to integrate location information and equipment data and send an execution command. The execution command can switch the method of obtaining location information. The communication positioning unit 2 can obtain location information and upload the location information and equipment data integrated by the CPU4 to the server 8. In this embodiment, the satellite positioning unit 1 is selected as GPS positioning and Beidou positioning, which adds a method of obtaining high-precision satellite signals.
[0032] Generally, when the cleaning device 11 is working outdoors, there are few obstructions, so the satellite positioning unit 1 can receive strong satellite signals outdoors. When the satellite positioning unit 1 receives good satellite signals, the satellite positioning unit 1 obtains the position information, and after the CPU 4 obtains the position information from the satellite positioning unit 1, it is integrated and then uploaded to the server 8 by the communication positioning unit 2.
[0033] Indoors, however, significant attenuation will occur when satellite signals pass through obstacles such as walls, glass, and metal of buildings, causing the strength of satellite signals received indoors to be greatly reduced and insufficient for effective positioning. Therefore, indoors, when the satellite positioning unit 1 cannot receive satellite signals, the CPU 4 sends an execution command to enable the communication positioning unit 2 to obtain location information. After obtaining the location information from the communication positioning unit 2, the CPU 4 integrates the location information, and the communication positioning unit 2 then uploads the location information to the server 8.
[0034] In one embodiment, the communication positioning unit 2 uses 2G / 3G / 4G cellular communication technology to achieve long-distance wireless communication.
[0035] The data acquisition unit 3 can acquire the status data of the cleaning device 11, and after integration by the CPU 4, upload the status data to the server 8 through the communication positioning unit 2. The user can understand whether the current cleaning device 11 is working normally based on the status data and try to avoid malfunction of the cleaning device 11.
[0036] refer to Figures 1 to 3In this embodiment, the communication positioning unit 2 includes a 4G module 21, which is electrically connected to the satellite positioning unit 1. The 4G module 21 is electrically connected to the CPU 4 through the serial port. The 4G module 21 uses base station positioning to obtain the location information of the current cleaning device 11. When the satellite positioning unit 1 cannot receive the satellite signal, the CPU 4 cannot receive the location information from the satellite positioning unit 1. Since the 4G module 21 is located through the base station and the 4G signal is covered, it can provide continuous positioning services indoors. The 4G module 21 is used first to obtain the location information of the current cleaning device 11, and an execution command is sent to enable the 4G module 21 to obtain the location information, which increases the way to obtain the location information indoors, so that the accuracy of obtaining the indoor location information is improved. The 4G module 21 can also upload the location information obtained by the CPU 4 to the server 8.
[0037] Furthermore, the communication positioning unit 2 also includes a WIFI module 22, which is electrically connected to the CPU 4 through a serial port. The WIFI module 22 obtains wireless LAN signals for positioning. Since the wireless LAN signal has strong penetrating power, in this embodiment, a wireless router is provided within the activity range of the cleaning device 11 to provide WIFI signals to the WIFI module 22. When the 4G module 21 cannot upload the location information and device data, the WIFI module 22 uploads them. When the satellite positioning unit 1 and the 4G signal cannot obtain the location information of the current cleaning device 11, the CPU 4 cannot receive the location information from the 4G module 21 and the satellite positioning unit 1, and sends an execution command to enable the WIFI module 22 to obtain the location information, thereby increasing the way to obtain the location information, so that the accuracy of obtaining the indoor location information is improved.
[0038] In this embodiment, when the firmware of the remote communication box 10 needs to be upgraded, the server 8 downloads the new version of the firmware to the remote communication box 10 through the 4G module 21 or the WIFI module 22 for upgrading.
[0039] Furthermore, the WIFI module 22 can set parameters of the remote communication box 10 through an APP installed on the mobile terminal.
[0040] Furthermore, the CPU4 is electrically connected to the RFID module 5 through the SPI bus. The RFID module 5 is used to locate the floor number. The RFID module 5 is electrically connected to the communication positioning unit 2. In this embodiment, a radio frequency card with floor number information needs to be installed on each floor in advance. When the RFID module 5 scans the radio frequency card of one of the floors, the floor number of the current cleaning device 11 can be obtained. After integrating the information of the floor number, the CPU4 uploads it to the server through the communication positioning unit 2 to accurately determine the location information to the floor where the current cleaning device 11 is located.
[0041] refer to Figure 1 , Figure 2 and Figure 4 The data acquisition unit 3 includes a current acquisition module 31 and a status acquisition module 32. The current acquisition module 31 is electrically connected to the CPU 4. When the cleaning device 11 adopts a lead-acid battery, the current acquisition module 31 can collect the charging and discharging current of the battery to obtain the power and status of the battery of the current cleaning device 11, and try to avoid the situation where the battery of the cleaning device 11 is insufficient and the battery is damaged. The status acquisition module 32 is provided with a lithium battery information interface 321 and a CAN interface 322 for receiving the device status. The lithium battery information interface 321 is used to connect to the BMS board of the lithium battery 111 of the cleaning device 11 and obtain the information of the lithium battery 111. Different ways of collecting the battery status can be used to adapt to a variety of different types of cleaning devices 11. The CAN interface 322 is used to connect to the controller 112 of the cleaning device 11 and obtain the motor status of the cleaning device 11. By obtaining the battery information and the device status, the cleaning device 11 can be troubleshooted in time.
[0042] Furthermore, CPU4 is electrically connected to a Flash storage module 6. When the signal of the communication positioning unit 2 is lost, it can store the location information from the satellite positioning unit 1 and the communication positioning unit 2, store the status data of the cleaning equipment 11 from the data acquisition unit 3, and store the floor number of the current cleaning equipment 11 from the RFID module 5. After the communication positioning unit 2 acquires the signal, CPU4 acquires the location information and equipment data of the Flash storage module 6 and re-uploads them to the server 8, thereby reducing the possibility of loss of location information and equipment data due to failure to upload them to the server 8.
[0043] Furthermore, the CPU 4 is electrically connected to a power management module 7, and the power management module 7 is electrically connected to the satellite positioning unit 1, the communication positioning unit 2, the data acquisition unit 3, the RFID module 5, and the Flash storage module 6. The power management module 7 is responsible for managing the power supply of the satellite positioning unit 1, the communication positioning unit 2, the data acquisition unit 3, the RFID module 5, and the Flash storage module 6. When not working for a long time, each unit and each module can be put into a dormant state to reduce battery consumption and battery over-discharge.
[0044] In addition, the lithium battery information interface 321 is an RS232 interface. The RS232 interface has strong anti-interference ability and can accurately obtain battery information in an Internet of Things box that needs to receive multiple wireless signals. The RS232 interface is used to connect the BMS board of the lithium battery in the cleaning equipment 11 to monitor and protect the circuit board of the lithium-ion battery.
[0045] The implementation principle of the embodiment of the present application is as follows: when there is a satellite signal, the location information of the current cleaning device 11 is obtained through the satellite positioning unit 1; when there is no satellite signal, the location information is obtained through the positioning of the WIFI module 22 or the base station positioning of the 4G module 21, and the floor information is obtained through the RFID module 5, and then the battery status and device status of the cleaning device 11 are obtained through the data acquisition unit 3. The acquired status data and location information of the cleaning device 11 are integrated by the CPU 4 and uploaded to the server 8 by the 4G module 21. When the 4G module 21 has no signal, the WIFI module 22 is used to upload the data. If there is no signal in the 4G module 21 and the WIFI module 22 when uploading the status data and location information of the cleaning device 11, the status data and location information will be first stored in the Flash storage module 6, and will be supplemented when the 4G module 21 or the WIFI module 22 has a signal.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
