Description

Technical Field

[0001] This utility model relates to the field of municipal products, specifically a portable road vehicle counter. Background Technology

[0002] Municipal roads are crucial hubs for urban economic development. As an important component of municipal engineering, municipal road reconstruction directly impacts a city's traffic capacity, playing a vital role in alleviating urban traffic congestion. However, municipal road reconstruction currently faces increasing challenges, especially with the growing number of private cars. This necessitates the collection and analysis of data on vehicle numbers and types at different times of day.

[0003] Currently, conventional vehicle information statistics mainly include: 1. Manual observation method: The observation time is generally a continuous period of time. This method is affected by human factors, which can lead to errors in the counting results. 2. Electronic measurement method: Commonly used equipment includes infrared sensors or inductors. For example, as shown in patent CN210324576U, the counting is performed through a signal transmitter. However, this patent cannot count traffic flow information for a specific time period. Alternatively, as shown in patent CN109087516A, the counting is performed using a laser transmitter buried in the road. This method is costly, complex to install, requires pre-burying equipment in the road, cannot be moved easily, and is inconvenient for construction and analysis. 3. Video and graphic monitoring method: This method monitors and counts the scene by installing cameras, as shown in patent CN220895024U. This method requires high-definition audio and video recording equipment, which is costly.

[0004] Therefore, this solution provides a low-cost portable counter that can count the number of vehicles passing through within a certain time period, thereby determining the frequency and timing of traffic jams on a certain road section. This allows for adjustments to the construction organization and facilitates road engineering renovation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a portable road vehicle counter, which solves the problems of high cost due to the need for pre-installed equipment or high-definition equipment, and low flexibility in not being able to collect vehicle information for a specific time period.

[0006] To solve the above problems, the technical solution adopted by this utility model is: a portable road vehicle counter, including a laser emission counter, a clock module, a microprocessor, a memory, and a power supply module for power supply. The laser emission counter includes a transmitting end and a receiving end respectively disposed on both sides of the road segment to be measured. The transmitting end is used to emit a laser beam, and the receiving end is used to receive the laser beam and generate an electrical signal. The clock module, the laser emission counter, and the memory are all communicatively connected to the microprocessor. When the microprocessor receives a counting signal triggered by the laser emission counter due to a vehicle blocking the laser beam, it synchronously obtains the current time information provided by the clock module, binds the counting result corresponding to the counting signal with the time information, and stores it in the memory.

[0007] Furthermore, it also includes height-adjustable brackets, with the transmitter and receiver respectively mounted on the top of the two brackets.

[0008] Furthermore, the clock module uses a high-precision real-time clock chip, supports 24-hour Gregorian calendar timekeeping, and has a power-off protection function.

[0009] Furthermore, the microprocessor via I 2 The clock module communicates via the C bus or SPI bus.

[0010] Furthermore, the memory is a removable storage device, including a storage chip or an SD card.

[0011] Furthermore, it also includes a display module, which is communicatively connected to the microprocessor and is used to display the number of vehicles passing through in real time.

[0012] Furthermore, the power module includes a photovoltaic panel, a power management circuit, and a battery; the photovoltaic panel is used to convert solar energy into electricity.

[0013] It can be converted into electrical energy. The power management circuit is used for power regulation and distribution, and for charging and discharging management of the battery.

[0014] Compared with existing technologies, the beneficial effects of this solution are:

[0015] 1. High Flexibility: The laser emission counter uses a foldable tripod or telescopic pole bracket to be installed on both sides of the road to be measured, providing excellent adaptability to various scenarios. The foldable structure facilitates the carrying and transportation of the counter, allowing for rapid deployment by staff at different monitoring locations.

[0016] 2. Low cost: The components of this counter are inexpensive and the photovoltaic effect is used to convert solar energy into electricity, further reducing costs.

[0017] 3. High practicality: This solution is equipped with a clock module, which can provide information on the number of vehicles passing through at different times. This facilitates subsequent analysis of traffic flow information during different holidays and time periods, thereby determining the frequency and timing patterns of traffic jams on a certain road section. As a result, the construction organization can be adjusted, which is conducive to road engineering renovation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1 is attached. Figure 1 As shown, a portable road vehicle counter is provided, including a laser emission counter 1, a clock module 2, a microprocessor 3, a memory 4, and a power supply module 5 for power supply. The laser emission counter 1 includes a transmitting end 11 and a receiving end 12 respectively disposed on both sides of the road segment to be measured. The transmitting end 11 is used to emit a laser beam, and the receiving end 12 is used to receive the laser beam and generate an electrical signal. The clock module 2, the laser emission counter 1, and the memory 4 are all communicatively connected to the microprocessor 3. When the microprocessor 3 receives a counting signal triggered by the laser emission counter 1 due to a vehicle blocking the laser beam, it synchronously obtains the current time information provided by the clock module 2, binds the counting result corresponding to the counting signal with the time information, and stores it in the memory 4.

[0023] Example 2 is attached. Figure 2 As shown, a portable road vehicle counter is provided. The clock module 2, the transmitter 11 of the laser emission counter 1, the display module 6, the memory 4, and the power module 5 are all mounted on the top of the bracket 7. The receiver 12 of the laser emission counter 1 and the power module 5 are mounted on the top of another bracket 7.

[0024] The bracket 7 is a foldable triangular bracket or a telescopic pole bracket to ensure the bracket is stable and can withstand the weight of other modules and the influence of the external environment. The height is adjustable and should be adjusted according to the height range of the vehicles to be counted, preferably 1m-1.2m, to ensure the counting of various vehicle types.

[0025] Clock module 2 uses a high-precision real-time clock chip, supports 24-hour Gregorian calendar timekeeping, and has power-off protection. The real-time clock chip is soldered onto a separate circuit board for clock module 2. Microprocessor 3 establishes a communication connection with clock module 2, using I / O... 2 Communication protocols such as C-bus or SPI bus are used to connect the microprocessor 3 to the clock module 2 where the high-precision real-time clock chip is located. The microprocessor 3 can obtain the time data output by the clock module 2, such as year, month, day, hour, minute, and second information.

[0026] The microprocessor 3 is communicatively connected to the laser emission counter 1, display module 6, and memory 4. A specific algorithm is programmed into the microprocessor 3. When the laser emitter 1 detects a vehicle passing by, the receiver 12 generates a counting trigger signal, which is transmitted to the microprocessor 3. The microprocessor 3 immediately performs a time acquisition operation, reading the current time data from the clock module 2. Then, the microprocessor 3 binds the counting result with the read time data and stores it in the memory 4. The memory 4 uses a suitable storage chip (such as a flash memory chip) soldered onto its circuit board, or a modular storage device, such as an SD memory card, can be used. The memory 4 is removable for easy data analysis on the computer.

[0027] Power module 5 includes a photovoltaic panel, a power management circuit, and a battery. The photovoltaic panel converts solar energy into electrical energy, while the power management circuit regulates and distributes the electrical energy and manages the charging and discharging of the battery. When the transmitter 11 and receiver 12 are powered by the photovoltaic panel, the battery serves as a power source for daytime energy storage and nighttime use. The photovoltaic panel is installed on top of the bracket 7 or in a sunny location to ensure maximum sunlight absorption. Connecting the photovoltaic panel to the battery provides a stable voltage to each module, ensuring the normal operation of the clock module 2, laser emission counter 1, memory 4, display module 6, microprocessor 3, etc. It also manages the charging and discharging of the battery, storing excess energy in the battery when there is sufficient sunlight, and powering the system when there is insufficient sunlight or at night, ensuring continuous operation of the instrument in various environments. The display module 6 communicates with the microprocessor 3 to display the number of vehicles passing in real time. The display module 6 uses an LED display screen.

[0028] Working Principle: The emitting end 11 of the laser emission counter 1 emits a concentrated, highly directional laser beam, forming a stable "laser barrier" between the emitting end 11 and the receiving end 12. When a vehicle enters this "laser barrier" area, it blocks the laser beam, causing the receiving end 12, which normally continuously receives the laser beam, to be unable to receive the laser signal. The receiving end 12 converts the received laser signal into an electrical signal. When the laser beam is blocked, its output electrical signal undergoes a significant change, such as changing from a high level to a low level. This change in electrical signal is transmitted to the microprocessor 3. The microprocessor 3 uses a preset algorithm to judge the signal change and confirm whether it is a valid vehicle passage signal, thereby realizing vehicle detection.

[0029] This device solves the problems in existing technologies, such as the need for pre-embedded equipment and the need to purchase high-definition equipment, resulting in high costs and the inability to obtain vehicle quantity information within a certain time period, thus affecting the adjustment of construction time.

[0030] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
