Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of label equipment, in particular to a novel tire pressure electronic label device. Background Art
[0002] For transportation companies and related manufacturers, tire pressure is a crucial piece of information in the daily management of numerous transport and engineering vehicles. Excessively high or low tire pressure can adversely affect the normal operation of the vehicle. Conventional technology typically relies on visual inspection by personnel, which is hampered by factors such as lack of experience. Furthermore, this unintuitive method does not guarantee accurate understanding of tire pressure data, posing potential safety risks to the safe operation of vehicles.
[0003] RFID tags are a contactless automatic identification technology that uses radio frequency signals to identify objects and retrieve relevant data, without human intervention. As a wireless version of barcodes, RFID tags offer advantages not found in barcodes, such as waterproofing, anti-magnetic properties, high temperature resistance, long service life, extended read range, data encryption, larger storage capacity, and the ability to easily modify stored information (they can also output data in real time). RFID tags use radio frequency transmission and reception. In practical applications, the reader of a handheld reader system that equips the RFID tag with an RF signal emits a signal. Upon receiving the signal, the RFID tag uses the energy gained from the induced current to transmit the product information stored in the chip (a passive tag, which does not require power but has a short data transmission distance limitation). Alternatively, the RFID tag actively transmits data signals (an active tag, which has a longer data transmission distance and is battery-powered, requiring battery replacement or recharging). The reader decodes the data and sends it to the reader system's information processing center for processing and displays the relevant data on the reader system's display interface. In summary, it is very necessary to provide an electronic tag device that can facilitate relevant management personnel to intuitively understand the corresponding vehicle and tire pressure data. Utility Model Content
[0004] In order to overcome the drawbacks of the existing vehicle management due to the manual visual observation of tire pressure data as described in the background technology, the utility model provides a new tire pressure electronic tag device based on an RFID electronic tag body, which can collect tire pressure data of vehicle tires in real time under the joint action of relevant mechanisms. Management personnel can understand the tire pressure data of the tires in real time at any time according to needs through a handheld reader matched with the RFID electronic tag body. The detected data is more intuitive and accurate, which provides favorable technical support for the safe driving of vehicles.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] A new tire pressure electronic tag device includes an active RFID electronic tag module body, a protective cover, and a single-chip computer module, and is characterized in that it also has a detection mechanism; the detection mechanism includes a cylinder, a piston, and a pressure sensor. The upper and lower ends of the cylinder are closed structures, an isolation plate is installed in the cylinder, and the lower end of the cylinder has a wire hole. Fixed plates are installed at the upper and lower ends of the piston, and a top column is installed on the lower fixed plate. The pressure sensor is installed at the lower end of the isolation plate with its force-bearing surface facing downward. The piston sealing sleeve is movable in the lower end of the cylinder, and the upper end is in contact with the force-bearing surface of the pressure sensor; the active RFID electronic tag module body and the single-chip computer module are installed at the upper end of the cylinder, the signal output end of the pressure sensor is electrically connected to the signal input end of the single-chip computer module, and the signal output end of the single-chip computer module is electrically connected to the signal input end of the active RFID electronic tag module body; the protective cover is installed at the outer end of the cylinder, and the lower end of the cylinder and the upper end of the vehicle tire valve are threaded together.
[0007] Furthermore, the socket of the charging socket is located outside the upper end of the cylinder, and a sealing plug is inserted into the socket.
[0008] Furthermore, the protective sleeve is elastic, the lower end of the protective sleeve is an open structure and the inner diameter is smaller than the outer diameter of the cylinder, the height of the protective sleeve is consistent with the height of the cylinder, and the protective sleeve is tightly sleeved on the outside of the cylinder.
[0009] Furthermore, the inner diameter of the fixing plate is smaller than the inner diameter of the cylinder, the piston is elastic and its outer diameter is larger than the inner diameter of the cylinder.
[0010] Furthermore, after the cylinder is connected to the air nozzle of the tire, the lower end of the push column pushes down the valve core of the air nozzle, and the air in the tire enters the lower end of the cylinder.
[0011] The beneficial effects of this utility model are as follows: Based on an active RFID electronic tag module, this new model can collect tire pressure data in real time through the combined action of a piston, pressure sensor, etc., and output this data to the signal input terminal of the RFID electronic tag. Managers can use the handheld reader that comes with the RFID electronic tag to obtain real-time tire pressure data at any time as needed, and can promptly address abnormal high or low tire pressure data (inflate if the pressure is too low, deflate if it is too high). Because workers do not need to visually inspect the tire's appearance to understand the tire pressure data, the measured data is more intuitive and accurate, providing favorable technical support for safe vehicle operation. Based on these advantages, this new model has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 4 This is a circuit diagram of the utility model. DETAILED DESCRIPTION
[0016] Figure 1 、 2 As shown in Figures 3 and 4, the new tire pressure electronic tag device includes an active RFID electronic tag module body Z3, a battery G1, a charging socket CZ1, a protective cover 1, a single-chip computer module Z2, and a detection mechanism 2; the detection mechanism includes a cylinder 21, a piston 22, and a pressure sensor Z1. The upper and lower ends of the cylinder 21 are closed structures. An isolation plate 23 is sealed and welded in the middle of the cylinder. There is a wire hole 24 in the middle of the lower end of the cylinder. The upper and lower ends of the piston 22 are respectively glued with a fixing plate 25 with an outer diameter smaller than its outer diameter (to increase the strength of the piston). A top column 26 is vertically welded in the middle of the lower end fixing plate. The pressure sensor Z1 is installed in the isolation plate. The piston 22 is sealed and movable in the middle of the lower end of the cylinder 21, and the upper fixed plate 25 is in contact with the force-bearing surface of the pressure sensor Z1. The active RFID electronic tag module body Z3, the battery G1, the charging socket CZ1, and the single-chip microcomputer module Z2 are installed on the circuit board. The circuit board is installed on the upper end of the isolation plate 23 and is located at the upper end of the cylinder 21. The two poles of the battery G1 and the two ends of the charging socket CZ1, the power input terminals 9 and 8 of the active RFID electronic tag module body Z3, the power input terminals 1 and 2 of the pressure sensor Z1, and the power input terminals 1 and 2 of the single-chip microcomputer module Z2 are respectively connected via wires. The signal output terminal 3 pins of the pressure sensor Z1 (and the wire connected to it are led upward through the opening at the left end of the isolation plate, and the opening is sealed with sealant) are connected to the signal input terminal 3 pins of the single-chip computer module Z2 via a wire, and the signal output terminal of the single-chip computer module Z2 is connected to the signal input terminal of the active RFID electronic tag module body Z3 via a wire; the protective cover 1 is installed on the outer end of the cylinder 21, and the threaded hole 24 at the lower end of the cylinder 21 and the upper end of the vehicle tire air valve 3 are sealed together via threads (the upper end of the air valve 3 is screwed into the internal thread of the threaded hole 24 at the lower end of the cylinder via an external thread to achieve a sealed connection between the two; because the threads are threaded, the cylinder and the air valve can be stably connected together).
[0017] Figure 1 、 2As shown in Figures 3 and 4, the socket of charging socket CZ1 is located outside the opening at the upper end of cylinder 21. A sealing rubber plug 27 with an outer diameter larger than the inner diameter of the socket is inserted into the socket (to prevent water from entering cylinder 21 in the event of damage to the protective sleeve in extreme cases. In actual use, the operator removes the protective sleeve and rubber plug and plugs the external power charger into charging socket CZ1 to charge battery G1, typically once every two months). The protective sleeve 1 (to prevent water from entering the cylinder in the event of damage to cylinder 21 in extreme cases) is a hollow rubber cylindrical structure. The lower end of the protective sleeve 1 is open and has an inner diameter slightly smaller than the outer diameter of cylinder 21. The height of the protective sleeve 1 is the same as that of cylinder 21, and the inner side of the protective sleeve 1 is tightly fitted around the outer side of cylinder 21. The inner diameter of the fixing plate 25 is smaller than the inner diameter of cylinder 21. The piston 22 is made of rubber and has an outer diameter slightly larger than the inner diameter of cylinder 21. After the cylinder 21 is connected to the air nozzle 3 of the tire, the lower end of the push column 26 pushes the valve core of the air nozzle 3 down a distance, and the air in the tire enters the lower end of the cylinder 21.
[0018] Figure 1 、 2 As shown in Figures 3 and 4, in this novel invention, the power output by the battery G1 enters the power input terminal of the active RFID electronic tag module body Z3, the pressure sensor Z1, and the single-chip computer module Z2, and the active RFID electronic tag module body Z3, the pressure sensor Z1, and the single-chip computer module Z2 are powered and work. After the gas in the tire 4 enters the lower end of the cylinder 21, the pressurized air will push the piston 22 upward. The greater the pressure in the tire 4, the greater the force exerted by the upper end of the piston on the force-bearing surface of the pressure sensor Z1. The signal voltage output from pin 3 of the pressure sensor Z1 to pin 3 of the single-chip module Z2 is relatively large. Conversely, the smaller the pressure in the tire 4, the greater the force exerted by the upper end of the piston on the force-bearing surface of the pressure sensor Z1 (the greater the pressure in the tire, the greater the pressure exerted by the piston on the force-bearing surface of the pressure sensor Z1 as it moves upward in the cylinder, and vice versa). The signal voltage output from pin 3 of the pressure sensor Z1 to pin 3 of the single-chip module Z2 is relatively small. After the dynamically changing analog voltage signal enters the single-chip module Z2, the single-chip module Z2 converts the analog voltage signal into a digital signal and outputs it to the signal input end of the active RFID electronic tag module body Z3. In actual applications, relevant management personnel place the receiving surface of the active RFID electronic tag module body Z3 and the matching handheld reader system (the new active RFID electronic tag module body Z3 in all areas can use a set of handheld reader systems to meet the data collection needs) close to the front end of the cylinder for a distance, and then receive the tire pressure data actively sent by the active RFID electronic tag module body Z3. The reader system's reader reads and decodes the information and sends it to the data processing center of the reader system for relevant data processing, and displays the relevant information (tire pressure data of the corresponding tire) on the display interface of the reader system.
[0019] Figure 1 、 2 As shown in Figures 3 and 4, this new technology, based on the active RFID electronic tag module, can collect real-time tire pressure data through the combined action of a piston, pressure sensor, and other elements. This data is then output to the signal input terminal of the RFID electronic tag. Management personnel can access real-time tire pressure data at any time as needed through a handheld reader that comes with the RFID electronic tag. They can also take immediate action if the tire pressure is abnormally high or low (inflate if it's too low, deflate if it's too high). Because workers don't need to visually inspect the tire's appearance to understand the tire pressure data, the measured data is more intuitive and accurate, providing valuable technical support for safe driving. Figure 4 As shown, the active RFID electronic tag module Z3 (capable of real-time data output) model is DSM-81, which has 14 pins, namely power test (control), power test (input), data output, data input (digital signal), transparent serial port baud rate setting 1 bit, transparent serial port baud rate setting 0 bit, reset control, power supply (negative), power supply (positive), control red light (output), control green light (output), control buzzer (output), transparent transmission status, activity indication port (except 9, 8, 5 pins, other pins are left floating); battery G1 is a 3.3V, 10Ah lithium battery; pressure sensor Z1 (matching There is a DC boost module. The power output of the DC boost module and the power input of the pressure sensor are connected via wires to convert the 3.3V DC power supply into DC 12V and provide a 12V working voltage for the pressure sensor. The power input of the DC boost module and the two poles of the battery are connected via wires. It is a miniature pressure sensor of model F9Y-A, which has two power input terminals and one signal output terminal. The greater the detected pressure, the higher the voltage signal output by the signal output terminal, and vice versa. The microcontroller module Z2 is model STM32 (the microcontroller module collects analog signals and converts them into digital signal output, which is an existing mature technology). This new Figure 4 All components are existing mature products, and this application does not elaborate on their working principles one by one.
