Description

Technical Field

[0001] This utility model relates to the technical field of toll station alarm devices, and in particular to a smart wearable bracelet that is linked with a toll station alarm for alerts. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] Toll stations are equipped with a variety of complex devices and systems to ensure the orderly passage of vehicles and the smooth operation of toll collection management. However, in actual operation, the alarm devices widely used at toll stations are audible and visual alarms, which have revealed significant drawbacks in practical use. Alarm signals include: UPS malfunction alarms, mains power malfunction alarms, vehicle overload alarms, ETC malfunction alarms, vehicle attempt to evade tolls alarms, and network malfunction alarms.

[0004] First, regarding the timeliness of staff response, when staff are performing tasks far from the alarm equipment within the toll station, such as guiding vehicles at the far end of the lane or inspecting facilities around the toll station, the audible and visual alarm signals are difficult to effectively transmit to them due to limitations in propagation distance and environmental factors. This is especially true at large toll stations, where the area is large and the building structure complex, making it difficult for staff to detect fault alarms in a timely manner. This delays the optimal time for fault handling and may further contribute to traffic congestion, affecting the overall efficiency of the toll station. Second, regarding the accuracy of alarm information, when multiple devices malfunction and alarm simultaneously, the on-site audible and visual alarm signals become chaotic. For staff, relying solely on these chaotic signals makes it difficult to quickly and accurately locate the specific faulty device. This not only increases the difficulty and time cost of troubleshooting but may also prevent timely handling of critical equipment malfunctions in emergencies, thus disrupting the normal operation of the toll station.

[0005] Furthermore, existing audible and visual alarms can only provide general alarm location information and cannot explain the specific reason for the alarm to staff. Moreover, existing audible and visual alarms disrupt the originally quiet and harmonious traffic environment of toll stations, which is detrimental to creating a peaceful and harmonious traffic environment.

[0012] As a further technical solution, the wireless transmission device also includes a button module, which is used to switch the working mode of the bracelet. The button module includes a first button, a second button, a third button, and a fourth button connected in parallel with each other.

[0013] As a further technical solution, one end of the first button, the second button, the third button, and the fourth button are connected to and grounded together, and the other ends of the first button, the second button, the third button, and the fourth button are respectively connected to the microprocessor unit.

[0014] As a further technical solution, the microprocessor unit is also connected to a temperature sensor module, which is used to monitor the temperature environment around the bracelet, wherein the data output terminal of the temperature sensor module is connected to the temperature acquisition terminal of the microprocessor unit.

[0031] Example 1

[0032] This utility model provides a smart wearable bracelet that is linked with a toll station alarm, including a shell and a wireless transmission device disposed inside the shell. In this embodiment, the shell is a waterproof shell.

[0033] The waterproof casing houses a Bluetooth wireless transmission device and a display module. The Bluetooth device is a ZW29 Bluetooth, and it is connected to the display module. Bluetooth receives alarm information from the tollbooth alarm and transmits it to the display module. The display module includes a microprocessor unit and a screen unit connected to the microprocessor unit, such as... Figure 2 As shown, the SCL and SDA terminals of the screen unit (OLED screen) are connected to the PA6 and PA7 terminals of the microprocessor unit, respectively. The microprocessor unit uses an STM32F103C8T6 minimum system board (U1) as its core processor, and the screen unit is an OLED screen. The display module performs digital filtering on the alarm information received via Bluetooth through the microprocessor unit. The digitally filtered signal is then displayed on the OLED screen. It should be noted that the microprocessor unit is an existing processor, and its digital filtering of alarm information is existing technology. This embodiment does not make any improvements to the digital filtering process.

[0034] like Figure 3 and 1 As shown, the Bluetooth receiver is used to receive alarm information from the toll station alarm, and the Bluetooth receiver (RX terminal) is also connected to the information input terminal (pin 6) of the microprocessor unit. The Bluetooth transmitter (TX terminal) is used to send feedback information to the toll station alarm, and the Bluetooth transmitter (TX terminal) is also connected to the information output terminal (pin 7) of the microprocessor unit.

[0035] In this embodiment, the wireless transmission device further includes a power module, which supplies power to power the power-consuming modules, such as the Bluetooth and display modules. Figure 4As shown, the power supply uses a miniUSB interface. In the power interface, + indicates the positive power supply (5V) and - indicates the negative power supply. The output terminal (4 pins) of the power module is connected to the power input terminals of the Bluetooth, microprocessor unit and screen unit respectively through the switch (U13). For example, the output terminal (4 pins) of the power module is connected to pin 18 of the microprocessor unit through the switch (U13).

[0036] In this embodiment, the wireless transmission device further includes a button module, which is used to switch the working mode of the bracelet, such as... Figure 5 As shown, the button module includes a first button KEY1, a second button KEY2, a third button KEY3, and a fourth button KEY4 connected in parallel. One end of each button is connected to and grounded. The other ends of each button are connected to the microprocessor unit. Specifically, the first button KEY1 is connected to pin 4 of the microprocessor unit via PB15, the second button KEY2 is connected to pin 3 of the microprocessor unit via PB14, the third button KEY3 is connected to pin 2 of the microprocessor unit via PB13, and the fourth button KEY4 is connected to pin 1 of the microprocessor unit via PB12.

[0037] In this embodiment, the microprocessor unit is also connected to a temperature sensor module, which is used to monitor the temperature environment around the bracelet, such as... Figure 6 As shown, the temperature sensor module is a DS18B20 temperature sensor (H3). The data output terminal (pin 2) of the DS18B20 temperature sensor is connected to the temperature acquisition terminal (pin 31) of the microprocessor unit. A resistor R1 is placed between the data output terminal and the power input terminal of the temperature sensor module. This is of significant reference value for monitoring the operating environment of temperature-sensitive equipment within the toll station, such as power supply equipment and servers.

Figure 8 As shown, the acceleration sensor module is an ADXL345 acceleration sensor (U6), and the data output terminal (pin 2) of the ADXL345 acceleration sensor is connected to the heart rate acquisition terminal (pin 32) of the microprocessor unit.

[0040] In this embodiment, the microprocessor unit is also provided with a backup power pin (VBAT), which is connected to a backup battery. When the power module fails, it can supply power to the wristband, preventing disruption to normal use.

[0041] The working principle of this utility model is as follows:

[0042] The alarm signal source triggers a relay via a switch, which in turn triggers a wireless signal transmitter to emit a signal. The Bluetooth device in the wristband receives the wireless signal (alarm signal) and transmits it to the microprocessor unit in the display module. After processing, the alarm information is displayed on the screen. The wristbands are independent of each other; each wristband can receive wireless signals from any alarm source, and each alarm source can also send its wireless signal to each wristband.

[0043] In this solution, the communication methods between the wireless signal transmitter and the wristband include, but are not limited to, various long-range wireless communication technologies such as 315 / 433MHz, LoRa, Sigfox, and NB-IoT.
