[0041] The embodiment of the present application discloses a device for quickly locating and finding an electric room in an underground garage.

[0042] See also Figure 1 An embodiment of the underground garage power room rapid positioning and searching device provided in the embodiments of the present application includes:

[0043] A control system 103 , a handheld positioning terminal 101 and several base stations 102 .

[0044] The control system 103 is in communication connection with a plurality of base stations 102 and a handheld positioning terminal 101 .

[0045] Several base stations 102 are arranged in the underground garage. The actual number of the base stations 102 is designed and changed according to actual needs and distributed in different locations of the underground garage.

[0046] The handheld positioning terminal 101 is connected to the base station 102 by UWB communication, and is used to send UWB communication signals to the base station 102. The UWB communication between the base station 102 and the handheld positioning terminal can achieve straight-line distance measurement of tens of meters.

[0047] The base station 102 is used to send a communication signal to the control system 103 when receiving the UWB communication signal sent by the handheld positioning terminal 101 .

[0048] The control system 103 is used to obtain the positioning information of each base station 102 and the handheld positioning terminal 101 when receiving the communication signal sent by the base station 102, and calculate the relative position information of the handheld positioning terminal 101 based on the positioning information of each base station 102 and the handheld positioning terminal 101, and then send the relative position information to the handheld positioning terminal 101.

[0049] The handheld positioning terminal 101 is also used to generate navigation information according to the relative position information sent by the control system 103 and the position information of the power room 105 in the underground garage.

[0050] The underground garage power room rapid positioning and searching device designed in the present application can realize the rapid positioning and searching of the underground garage power room 105 based on the UWB wireless communication principle without the help of operator signals and GPS through the cooperation of the control system 103, the handheld positioning terminal 101 and several base stations 102 (realizing the automatic positioning and navigation function of the underground garage without GPS signals), thereby reducing the time for staff to search for the power room 105. The staff can plan the work route more reasonably and avoid blind running in the process of searching for the power room 105, and devote more time and energy to the actual emergency and power restoration work, thereby effectively reducing the emergency and power restoration time and improving work efficiency, power supply reliability and customer satisfaction.

[0051] The above is the first embodiment of the underground garage power room rapid positioning and searching device provided by the embodiment of the present application. The following is the second embodiment of the underground garage power room rapid positioning and searching device provided by the embodiment of the present application. For details, please refer to Figure 1 to Figure 2 .

[0052] Based on the solution of the above embodiment 1:

[0053] Furthermore, the base station 102 can be connected to the backup power supply of the power room 105 by wire, or have its own rechargeable battery. It is usually powered by the power grid. If there is a power outage, it will switch to the rechargeable battery or backup power supply to maintain power supply. It can ensure normal operation for a period of time even in the case of a power outage, avoid the problem of no signal caused by power outage, and effectively improve the search speed of the power room 105.

[0054] Similarly, the control system 103 can also be connected to the backup power supply of the power room 105 by wire, or have its own rechargeable battery. It is usually powered by the power grid. If there is a power outage, it will switch to the rechargeable battery or backup power supply to maintain power supply. In the case of a power outage, it can ensure normal operation for a period of time, avoid the problem of no signal caused by power outage, and effectively improve the search speed of the power room 105.

[0055] Specifically, preferably, the control system 103 and the base station 102 are both connected to a UPS power supply.

[0056] UPS (Uninterruptible Power Supply) is a constant voltage and frequency uninterruptible power supply that contains an energy storage device and has an inverter as its main component.

[0057] When the mains power is normal, the UPS will stabilize the mains power and supply it to the load, and it will also charge the battery inside the machine. When the mains power is interrupted (power outage), the UPS will immediately switch the DC power of the battery to the 220V AC power of the load through the inverter, so that the load can maintain normal operation and protect the load software and hardware from damage.

[0058] Furthermore, for the design of the control system 103, it can be integrated into the power room 105 without additional layout, saving installation and layout costs. The control system 103 can include a corresponding host computer or PC. If a PC is used as the control system 103, multiple base stations 102 can be controlled by network cables or wireless communication.

[0059] Furthermore, a server 104 is also included, and the control system 103 is in communication connection with the server 104; the server 104 may be a server 104 of the power department.

[0060] The control system 103 can communicate with the server 104 of the power department in a wired or wireless manner, and use the database of the server 104 to store relevant power equipment information of the underground garage.

[0061] The server 104 is connected to the handheld positioning terminal 101 through communication (such as WiFi, 5G network, etc.), and the control system 103 sends the relative position information to the handheld positioning terminal 101 through the server 104 .

[0062] Furthermore, for the design of the handheld positioning terminal 101, it can be a positioning terminal with a UWB ranging module, which can realize the UWB positioning function by connecting a single-chip microcomputer, Raspberry Pi or Android device to a UWB antenna. The UWB communication module can also be connected to a mobile smart terminal such as a mobile phone through a wireless connection method such as Bluetooth and WIFI, thereby utilizing the powerful program running capabilities of the mobile smart terminal to achieve the improvement of the UWB positioning function.

[0063] More specifically, the handheld positioning terminal can be a long-distance positioning LD600(-I) module in the HR-RTLS1 series products, which uses DecaWave's DW1000 as the core UWB chip, uses STM32F103CBT6 (or compatible GD32F103CBT6) microcontroller as the main control MCU, has a housing and an external antenna, and has a built-in rechargeable lithium battery. It has the characteristics of being easy to use, high precision, and compact. The LD600(-I) module can be used as a base station 102 or a tag. Multiple LD600(-I) modules or other HR-RTLS1 series modules (ULM1, LD150(-I), IGA01-EP, ULM1-SH, ULM1-GP) can be used together to form a complete positioning system development kit. Compared with the LD600 module, the LD600-I module has an additional built-in IMU chip MPU-9250 / ICM-20948, which integrates a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer, which can be used to assist in attitude calculation and UWB and IMU fusion positioning.

[0064] Furthermore, for the design of base station 102, base station 102 can adopt IGA01-EP base station 102 for long-distance positioning in HR-RTLS1 series products, using DecaWave's DW1000 as the core UWB chip, using ESP32 single-chip microcomputer as the main control MCU, with a housing and built-in antenna, supporting POE power supply and Ethernet communication, and having the characteristics of being easy to use and high precision. Multiple IGA01-EP base stations 102 or with other HR-RTLS1 series modules (ULM1, LD150(-I), LD600(-I), ULM1-SH, ULM1-GP) can form a complete positioning system development kit.

[0065] The handheld positioning terminal of the present application can be implemented by using the LD600(-I) module alone, or the LD600(-I) module can be used together with a smart mobile terminal such as a mobile phone.

[0066] Furthermore, the handheld positioning terminal 101 has a display to intuitively display navigation information. The specific navigation information can be as follows: Figure 2As shown, it includes a navigation route, a base station 102 location point, and a power room 105 location point, etc., without specific limitation.

[0067] Furthermore, it also includes a sound module 106, which is arranged on the handheld positioning terminal 101 and is connected to the handheld positioning terminal 101 in communication. The sound module 106 has a flexible setting method. It can be built into the handheld positioning terminal 101 and become an integrated module inside it. In this case, the overall structure of the handheld positioning terminal 101 is more compact, easy to carry and operate. The built-in sound module 106 can work in conjunction with other components of the handheld positioning terminal 101 to achieve seamless information interaction and function execution. For example, when receiving relevant instructions, it can respond quickly and make a sound without additional connection and setting steps. The sound module 106 can also be connected to the handheld positioning terminal 101 as an external device. This external connection method provides more flexibility for the configuration of the system. For example, in some special cases, if a more powerful sound effect is required, or the internal space of the original handheld positioning terminal 101 is limited and cannot accommodate a sound module 106 of a specific specification, an external connection method can be selected. The external sound module 106 can communicate and connect with the handheld positioning terminal 101 through a standard interface (such as USB, Bluetooth, etc.), and can be replaced or upgraded according to actual needs to meet the usage requirements in different scenarios.

[0068] The control system 103 is also used to calculate the distance between the current handheld positioning terminal 101 and the power room 105 according to the relative position information of the current handheld positioning terminal 101 and the position information of the power room 105 in the underground garage; when the control system 103 determines that the distance between the current handheld positioning terminal 101 and the power room 105 is less than a preset value, the handheld positioning terminal 101 is controlled to run the sound module 106, and at this time, the sound module 106 will make a sound to remind the maintenance personnel. The sound can be clearly heard by the maintenance personnel in the noisy underground garage environment, and even if the maintenance personnel are in a state of distraction, it can quickly attract their attention.

[0069] The light emitting module 107 is disposed outside the power room 105 and is in communication connection with the control system 101. The control system 101 is also used to control the light emitting module 107 to operate when it is determined that the distance between the handheld positioning terminal 101 and the power room 105 is less than a preset value.

[0070] The light-emitting module 107 can use a high-brightness indicator light or a flashing light, which has a strong visual impact in a dimly lit underground garage, allowing maintenance personnel to see the prompt signal at a long distance; this combination of reminders through the sound module 106 and the light-emitting module 107 is of great help to maintenance personnel in quickly finding the location of the power room 105 in the underground garage.

[0071] The working principle of the underground garage power room rapid positioning and searching device designed in this application is as follows:

[0072] 1. Taking the connection server 104 as an example, when the underground garage is built, the drawing data of the underground garage is stored in the corresponding server 104; the drawing contains the terrain of the underground garage, the power room 105 and the specific location information of each base station 102. The specific location information can be generated based on the preset map coordinate system. The handheld positioning terminal 101 or other equipment can obtain the relative position of the power room 105 and each base station 102 in the underground garage through the specific location data. At the same time, the drawing data also includes the location information of the walls, parking spaces and pillars of the underground garage for subsequent navigation.

[0073] Under the above design, the handheld positioning terminal 101 can obtain the corresponding underground garage drawing data from the server 104 through networking (such as WIFI or 5G network). After the handheld positioning terminal 101 obtains the underground garage drawing data, it can display the location of the power room 105 (which can also include each base station 102) of the underground garage through the display screen set on the terminal.

[0074] Of course, the handheld positioning terminal 101 can also read the required drawing data in advance through a wired method or a card insertion method.

[0075] 2. When the maintenance personnel arrive at the underground garage, they turn on the navigation mode of the handheld positioning terminal 101. The handheld positioning terminal 101 can establish communication with the base station 102 near the current position through its own UWB communication module and start the positioning function.

[0076] 3. After receiving the communication signal of the handheld positioning terminal 101, the nearby base station 102 will send a communication signal to the control system 103. The control system 103 will then actively obtain the positioning information of each base station 102 and the handheld positioning terminal 101, and calculate the relative position of the handheld positioning terminal 101 in the map coordinate system based on the positioning information of each base station 102 and the handheld positioning terminal 101. Then the relative position of the handheld positioning terminal 101 is packaged into a data packet and transmitted to the server 104. After receiving the data packet, the server 104 will forward it to the handheld positioning terminal 101.

[0077] 4. After receiving the data packet, the handheld positioning terminal 101 will parse it and import its data into the corresponding drawing data, so as to obtain the current specific location of the handheld positioning terminal 101 in the underground garage, and generate corresponding navigation information based on the current location and the location of the power room 105 in the underground garage.

[0078] The navigation information can be actively combined with the drawing data of the underground garage and the obstacles of the underground garage (such as walls, parking spaces or load-bearing columns, etc.) to provide the fastest navigation route to the power room 105, and provide prompts through the display on the handheld positioning terminal 101 and the speaker (sound module 106) broadcast, thereby actively guiding maintenance personnel to the power room 105.

[0079] Furthermore, the control system 103 is also used to actively obtain the positioning information of each base station 102 and the handheld positioning terminal 101 at a preset interval when the handheld positioning terminal 101 is in the navigation process, and calculate the relative position information of the handheld positioning terminal 101 based on the positioning information of each base station 102 and the handheld positioning terminal 101, and then send the relative position information to the handheld positioning terminal 101. During the navigation process, the control system 103 will continuously and actively obtain (for example, at intervals of 1-3 seconds or even shorter) the relative position information between each base station 102 and the handheld positioning terminal 101 to determine the current position of the handheld positioning terminal 101, and forward it to the handheld positioning terminal 101 through the server 104, thereby realizing the real-time navigation display function of the handheld positioning terminal 101.

[0080] Furthermore, the control system 103 is also connected to the power room 105 for communication, so as to obtain the fault information of the power room 105 and send it to the handheld positioning terminal 101 through the server 104. Specifically, the handheld positioning terminal 101 can obtain the fault type of a certain power room 105 sent by the control system 103 through the server 104. For example, the control system 103 can monitor the tripping condition of a certain power room 105, send a tripping signal to the handheld positioning terminal 101, and provide a fault prompt to the maintenance personnel through the handheld positioning terminal 101.

[0081] Of course, the control system 103 may also be provided with an automatic alarm function, and when a sudden fault is detected, a signal is actively sent to the handheld positioning terminal 101, so that maintenance personnel can quickly learn that the faulty power room 105 has occurred.

[0082] Furthermore, the control system 103 is also used to send the location information of the power room 105 with a fault to the handheld positioning terminal 101 through the server 104 .

[0083] Specifically, in special cases, such as when the underground garage is relatively large and has more than two power rooms 105, the control system 103 can monitor the power rooms 105. When a power room 105 fails, the location information of the power room 105 with the failure is directly sent to the server 104, and the server 104 notifies the handheld positioning terminal 101. At this time, the navigation function of the handheld positioning terminal 101 can actively navigate the maintenance personnel to the power room 105 with the failure, so as to avoid going to the power room 105 that is operating normally. Of course, in addition to this, the maintenance personnel can also manually select the location of the power room 105 they want to reach and execute the navigation function by operating the handheld positioning terminal 101, so as to avoid going to the wrong place.

[0084] like Figure 3 As shown, the present application also discloses a method for quickly locating and finding an underground garage power room, which is applied to a device for quickly locating and finding an underground garage power room, comprising the steps of:

[0085] S1 , the maintenance personnel activates the navigation mode of the handheld positioning terminal 101 , so that the handheld positioning terminal 101 establishes a UWB communication connection with a base station 102 near the current position, wherein the base station 102 establishing the UWB communication connection sends a communication signal to the control system 103 .

[0086] S2, the maintenance personnel find the warehouse according to the navigation information generated by the handheld positioning terminal 101 based on the relative position information of the handheld positioning terminal 101 sent by the control system 103 and the position information of the power room 105 in the underground garage, wherein the relative position information is obtained by the control system 103 when receiving the communication signal sent by the base station 102, and the positioning information of each base station 102 and the handheld positioning terminal 101 is obtained and calculated based on the positioning information of each base station 102 and the handheld positioning terminal 101.

[0087] The above is a detailed introduction to the underground garage power room rapid positioning and searching device and method provided by the present application. For a general technician in this field, according to the ideas of the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
