Problems solved by technology

However, regardless of the existing parking locks, when considering the pressure-resistant design, they rely too much on the metal shell, resulting in serious attenuation of the wireless signal, and the wireless control distance of the parking lock is short, which cannot meet the actual needs of users and the market.
In order to compensate for the influence of the metal shell on the wireless signal, most parking lock manufacturers adopt the design of digging or slotting in the metal shell to improve the radiation intensity and receiving sensitivity of the wireless signal, but the effect is reflected in the communication control distance. still not ideal

specific Embodiment approach 1

[0024] combine figure 1 , 2 , 3, 4, and 5 illustrate this embodiment. A device that uses an SMC shell to enhance the communication signal of a parking lock includes a parking lock shell, a controller, a sensor, a buzzer, a drive circuit, a motor, and a mechanical transmission mechanism. , power supply, power management circuit, communication module, antenna, and mobile terminal, the resin material shell made of SMC technology replaces the metal shell to completely eliminate the influence of the metal shell on the radio frequency signal. Compared with the metal case, the receiving strength of the RF signal of the parking lock can be increased by more than 20dB. The use of the SMC shell, while increasing the effective wireless control distance, can ensure that the lock body has a good anti-pressure effect, meeting the needs of end users and the market.

[0036] combine figure 1 , 2 , 3, 4, and 5 illustrate this embodiment, and the parking lock shell adopts SMC process resin shell. Applying the SMC process resin shell to the intelligent wireless parking lock, compared with the metal shell, the receiving strength of the radio frequency signal can be increased by more than 20dB, and the communication distance between the mobile phone Bluetooth and the parking lock can be increased by 10-30 meters or even farther; Repeater and antenna design, the communication distance between the parking lock and the repeater in the ZigBee network can be increased by 30-100 meters or even further.

specific Embodiment approach 3

[0037] combine figure 1 , 2, 3, 4, and 5 illustrate this embodiment, and the controller adopts a STM32L series single-chip microcomputer. The STM32L series has added two low-power modes, low-power operation and low-power sleep. By using ultra-low power regulators and oscillators, the microcontroller can greatly reduce the operating power consumption at low frequencies. . The regulator does not depend on the supply voltage to meet the current requirement. STM32L also provides dynamic voltage boost function, which is an energy-saving technology that has been successfully applied for many years, which can further reduce the internal working voltage of the chip when it is running at low and medium frequencies. In normal operating mode, the current consumption of the flash memory is as low as 230μA / MHz, and the power / performance ratio of STM32L is as low as 185μA / DMIPS. STM32L circuits are designed to achieve high performance at low voltage, effectively extending the charging i...

Description

technical field [0001] The present invention mainly relates to a method for enhancing the wireless communication signal of a parking lock, and more specifically relates to a device and method for enhancing the communication signal of a parking lock by using an SMC shell. Background technique [0002] With the rapid growth of the number of private cars, the resources of parking spaces are getting tighter and tighter. In order to ensure that private parking spaces are not occupied by others, the use of parking locks is becoming more and more common, which is a good guarantee that one's own parking spaces will not be occupied by others. The birth of the intelligent wireless control remote control parking lock overcomes the disadvantages of non-automation of the mechanical parking lock, and the communication distance can reach more than 30m. At the same time, it can avoid carrying the remote control with you, which greatly facilitates the car owner. There are two main types of w...
