Description

Technical Field

[0001] The present invention relates to the field of automobile control technology, and in particular to a commercial vehicle anti-theft alarm system and method. Background Art

[0002] Commercial vehicles, as an effective carrier of intercity logistics, constitute an important part of the transportation and trade network. How to protect the safety of commercial vehicle systems such as fuel, post-processing, lidar, and batteries while the vehicles are parked has become a key focus. Therefore, commercial vehicle anti-theft alarm methods have emerged. The most common theft methods are violent demolition, cutting and theft, or removing bolts. To address the above three theft methods, anti-theft alarms and false alarm management strategies are implemented, and vibration sensors are configured to achieve commercial vehicle anti-theft, anti-dismantling, and anti-breaking functions. Sound and light alarms are driven to provide voice reminders to criminals, effectively protecting the vehicle while achieving a deterrent and restraining effect. Summary of the Invention

[0003] The purpose of the present invention is to provide a commercial vehicle anti-theft alarm system to address the shortcomings of the existing technology, thereby solving the problem of poor safety of the existing commercial vehicle protection systems such as fuel, post-processing, laser radar, and battery when the vehicle is parked.

[0004] The present invention is achieved by adopting the following technical solutions:

[0005] A commercial vehicle anti-theft alarm system includes a remote controller, a vibration sensor, an audible and visual alarm, and a controller; the controller is arranged in the cab; the vibration sensor is arranged on the inner side of the chassis frame and is connected to the controller via a CAN bus; the audible and visual alarm is arranged in the front cover and is connected to the controller via a CAN bus; the remote controller and the controller are wirelessly connected.

[0006] Preferably, it further includes a human microwave sensor and a behavior recognition camera; the behavior recognition camera and the human microwave sensor are arranged outside the vehicle body and are respectively connected to the controller via a CAN bus.

[0007] Preferably, the device further comprises a display screen, wherein the display screen is connected to the controller via a CAN bus.

[0008] Preferably, the device further comprises an anti-theft switch, wherein the anti-theft switch is connected to the controller via a CAN bus.

[0009] Preferably, the device further comprises a mobile power supply, wherein the mobile power supply is connected to the controller via a CAN bus.

[0010] It also includes a data platform terminal; the data platform terminal is connected to the controller via a CAN bus.

[0011] A method for a commercial vehicle anti-theft alarm system comprises the following steps:

[0012] Step 1: The controller determines the state of the anti-theft switch. If the anti-theft switch is on, the vehicle is powered on. If the anti-theft switch is off, the vehicle is powered on.

[0013] Step 2: Determine the vehicle power status. If the vehicle power status is on, proceed to the step of determining whether the vehicle speed is 0; if the anti-theft switch is off, proceed to the step of whether the vibration sensor is calibrated;

[0014] Step 3: Determine whether the vehicle speed is 0. If the vehicle speed is 0, enter the vibration sensor calibration step; if the vehicle speed is not 0, enter the sleep step;

[0015] Step 4: Determine whether the vibration sensor is calibrated. If the vibration sensor is calibrated, the vibration sensor performs detection and timing. If the vibration sensor is not calibrated, the vibration sensor is calibrated, and then the vibration sensor performs detection and timing.

[0016] Step 5: Determine whether the vibration signal is valid. If so, enter the alarm start and timing step. Otherwise, the vibration sensor will enter the sleep step after detecting for 5 seconds.

[0017] Step 6: After the alarm is turned on and the timing is started, determine whether the function switch is turned off or the key is unlocked twice in succession. If so, enter the alarm interruption step; otherwise, the system alarms for 2 minutes and then enters the sleep step;

[0018] Step 7: When entering the sleep step, the system starts timing, the sleep period lasts for 10 seconds, and then enters the wake-up step to detect the vibration signal for 5 seconds. If there is no vibration signal within 5 seconds, the system enters the sleep state for 10 seconds, then wakes up, and repeats this cycle. Compared with the existing technology, the present invention has the following beneficial technical effects:

[0019] A commercial vehicle anti-theft alarm system and method of the present invention includes a vibration sensor and an integrated controller. Depending on the application scenario, it has the advantages of simple system composition, low cost, high reliability, easy layout, and good compatibility. Compared with traditional anti-theft means, this system is intelligent, integrated, and highly modularized, with a low false alarm rate. For any vehicle model, an anti-theft switch (anti-theft remote control) and a backup power supply are set to turn the anti-theft alarm system on / off and provide emergency power supply. At the same time, according to the sleep wake-up logic, system false alarm management is realized. BRIEF DESCRIPTION OF THE DRAWINGS
