Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0021] This application provides a handheld wireless tire pressure and temperature detection device. By installing an integrated sensor in the tire and using a matching handheld detection gun externally to acquire sensor data, the device can obtain tire temperature and tire pressure data of the tire in use. This data can be used for safety monitoring and to determine whether the tire condition meets the requirements for safe vehicle operation. At the same time, the relevant tire sensor data can be uploaded to the cloud for remote and unified management.
[0022] See Figure 1 , Figure 2 and Figure 3The handheld wireless tire pressure and temperature detection device provided in this application includes a handheld detection gun 100 and an integrated sensor 200 built into the tire. The integrated sensor 200 includes a hollow housing 201, and a main control board 202 is provided inside the housing 201. The main control board 202 is connected to a temperature sensor 203, a tire pressure sensor 204, and a first wireless module 205. The housing 201 also contains a battery (not shown in the figure) connected to the main control board 202 for power supply. The handheld detection gun 100 includes a handheld housing and a battery unit, a power supply control unit, a main control unit, and a remote communication unit disposed inside the housing. The battery unit is connected to the power supply control unit. The power supply control unit has an independent power supply module that can be independently controlled to switch on and off. The power supply control unit is connected to the main control unit. The independent power supply module is connected to the remote communication unit. The remote communication unit is communicatively connected to the main control unit. The main control unit has a second wireless module for communicating with the first wireless module.
[0023] In this embodiment, the power supply control unit is equipped with an independent power supply module, providing separate and independent power to the remote communication unit, thereby allowing independent control of power supply or disconnection. When the manager uses the handheld detection gun to communicate with the integrated sensor to obtain tire temperature and pressure data, they can view the data locally using the handheld detection gun without the need for the remote communication unit, saving power by disconnecting the independent power supply module; alternatively, they can connect to the network, requiring the remote communication unit to communicate with the cloud. After the manager uses the handheld detection gun to obtain tire temperature and pressure data, the relevant data can be uploaded to the cloud in real time. For example, a first master control switch 101 (power button) is provided on the housing to control the power supply control unit to be on or off, controlling the activation of the handheld detection gun. In an optional embodiment, an electronic switch controls the on or off of the independent power supply module, controlled by the main control unit. In yet another optional embodiment, a second manual switch 102, located on the housing, can also control the on or off of the independent power supply module, manually controlled by the manager using the handheld detection gun.
[0024] The integrated sensor 200 provided in this application needs to be embedded in the tire. For vehicles already in operation, each tire needs to be removed and the integrated sensor 200 installed (usually by adhesive bonding) for hardware updates. The handheld detection gun can be used for one-to-many or many-to-many connections. Each integrated sensor 200 has a unique ID. One handheld detection gun can be used for multiple tires on several vehicles to periodically collect data from each tire on each vehicle according to the maintenance cycle. Alternatively, multiple handheld detection guns can be used, carried by on-duty drivers or on-site logistics management personnel, to acquire tire data in real time. The integrated sensor provided in this application has the same structural principle and function as existing built-in tire pressure and temperature sensors. The difference is that the vehicle receiver is eliminated and replaced by a handheld detection gun, making it more flexible for large-scale operation scenarios such as buses, public buses, and trucks, resulting in lower retrofit costs and wider application.
[0025] Specifically, for the integrated sensor 200, the main control board 202 is connected to a first storage module 206 that stores data from the temperature sensor and tire pressure sensor. The integrated sensor 200 periodically collects temperature and tire pressure data and stores it in the first storage module 206. When the handheld detection gun is wirelessly connected to the integrated sensor, the stored data is transmitted to the handheld detection gun. For example, the first storage module uses conventional electronic components such as storage chips and memory.
[0026] In an optional implementation, the first and second wireless modules are configured as 433MHz wireless modules or low-frequency wireless modules. These modules feature low power consumption and short-range communication capabilities, and their inclusion in the integrated sensor improves the sensor's battery life.
[0027] In a further embodiment, for the handheld detection gun, the main control unit includes a main control chip (MCU), which is connected to the wireless module and the remote communication unit. The main control unit also includes a button module 103, a display module 104, and a second storage module connected to the MCU. The button module 103 and display module 104 serve as human-machine interface modules, disposed on the surface of the housing, for human-machine interaction with the operator using the handheld detection gun. When the operator wirelessly acquires tire temperature and pressure data using the handheld detection gun, the corresponding tire is uniquely identified by the ID fed back from the integrated sensor. The main control unit receives the uncollected tire temperature and pressure data stored in the first storage module 206 from the integrated sensor, and then stores it in the second storage module of the handheld detection gun. The display module presents all data to the operator in chronological order. The operator can also adjust the display method of relevant data, query historical data, etc., using buttons or a touchscreen, and can also be guided to update the sensor firmware using buttons and a touchscreen. Once the handheld tire sensor has acquired a significant amount of data, it needs to connect to the cloud and upload it. Administrators can activate the remote communication unit of the handheld sensor to simultaneously upload all sensor data stored in the second storage module to the cloud. Remote personnel can then view and evaluate tire temperature and pressure data through the cloud platform, and analyze tire conditions and whether replacement is necessary.
[0028] In a specific embodiment, the handheld housing includes a main body and a handheld part 110. The main body is square-shaped, and the second wireless module 105 is located at one end of the main body away from the handheld part. The remote communication unit is preferably located at the other end away from the second wireless module to reduce mutual interference between the second wireless module and the remote communication unit. For example, the remote communication unit includes a communication module and a communication antenna. The communication module includes one or more of a 4G module, a 5G module, or a WiFi module.
[0029] In a specific implementation, the battery unit is a battery pack, and the casing has a battery compartment for accommodating the battery pack. The battery pack can be made of four common AA batteries. The power supply control unit's basic power supply module is a 5V power supply module that powers the second wireless module and the display module, a 3.3V power supply module that connects to the main control chip (MCU) of the central control unit, and an independent power supply module is a 3.8V power supply module that connects to the communication module of the remote communication unit.
[0030] The above description is merely a preferred embodiment of this application and does not constitute any limitation on this application in any form or substance. It should be noted that those skilled in the art can make several improvements and additions without departing from this application, and these improvements and additions should also be considered within the scope of protection of this application.
