[0002] With the improvement of people's living standards, cars are used more and more frequently in people's daily lives, the number of cars owned is increasing, and traffic conditions are becoming more and more complicated. When drivers are not using their cars, they are paying more and more attention to the safety of their cars. The parking sentry monitoring system has been created to greatly help car owners solve the problem of damage to their legitimate rights and interests caused by accidents such as bumps and collisions after parking.

[0003] The existing vehicle-mounted sentry monitoring system is generally connected to the vehicle's on-board system. Every time it is turned on, even during standby mode, it will consume a lot of vehicle electricity. Generally, only high-end new energy vehicles can be equipped with this function. Fuel vehicles can basically not use this function, and it has high requirements for the vehicle's power system. Moreover, the current parking sentry control system requires multiple sensing detection devices, which has high requirements for the data processing performance of the on-board system. As a result, the user cost of using the current system remains high, and it is generally inconvenient for ordinary users, especially fuel vehicle users.

[0004] In summary, the existing sentry monitoring system has the following defects: 1. The existing sentry control system is connected to the vehicle system, involving many systems, so the overall power consumption of the equipment is relatively high even in standby mode; 2. At the same time, due to the need for many sensors, the entire set of equipment is expensive and most users cannot use it; 3. Moreover, the current vehicle-mounted sentry systems are all designed by the original car manufacturer, and users cannot set up multiple sets of monitoring by themselves, and personalize the recording position and recording duration.

[0015] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] In this application, a 5-32V DC power supply can be selected as the power supply 1. The input power management module 2, the microwave radar detection module 3 and the output power module 4 are purchased directly from the market according to different models and then matched and installed for use.

[0017] See Figure 1 The figure shows a low-cost, low-power self-assembled sentry control system for an automobile, including a power supply 1, an input power management module 2, a microwave radar detection module 3 and an output power management module 4; the negative poles of the power supply 1, the input power management module 2, the microwave radar detection module 3 and the output power management module 4 are connected in sequence.

[0018] The input power management module 2 includes three inputs and one output: the positive power input, the negative power input, and the ACC control signal input; and the positive power output. The microwave radar detection module 3 includes two inputs and one output: the positive power input and the negative power input; and the control information output. The output power management module 4 includes three inputs and two outputs: the positive power input, the negative power input, and the control signal input; and the positive power output and the negative power output. Power supply 1 uses a 5-32V DC power supply.

[0019] Example 1:

[0020] First, connect the above equipment to the vehicle according to the instructions, select a 12V DC power supply, and place the radar inspection module in the passenger seat, ensuring that its back is parallel to the passenger window and its front is parallel to the driver's window. When the vehicle is parked and locked, the microwave radar detection module enters standby mode. When someone moves near the vehicle, the microwave radar detection module enters working mode, and the load equipment starts working.

[0021] The payload can be one or more recording devices that start recording when powered on, such as a newer, less frequently used mobile phone with software that starts recording when powered on and stops recording when not powered on. These devices can be placed at different locations on the vehicle to record video from different locations.

[0022] In this application, the positive power input of the input power management module 2 is connected to the normal positive pole of the power supply, the negative power input is connected to the normal negative pole of the power supply, and the ACC control signal input is connected to the positive pole of the ACC power supply. When the vehicle starts, the ACC signal has a signal, and the positive power output of the input power management module 2 stops the power output. When the vehicle is locked, the ACC signal has no signal, and the positive power output of the input power management module 2 starts the power output.

[0023] The positive power input of microwave radar detection module 3 is connected to the positive power output of input power management module 2, while its negative power input is connected to the negative power input of input power management module 2. When the vehicle is locked, the positive power output of input power management module 2 starts powering the positive power input of microwave radar detection module 3. At this point, microwave radar detection module 3 is powered and begins operating. If a moving object around the vehicle enters the detection range of the microwave radar detection module, the control signal output point of the microwave radar detection module outputs a corresponding control signal.

[0024] The positive power input of the output power management module 4 is connected to the positive power input of the microwave radar detection module 3, the negative power input of the output power management module 4 is connected to the negative power input of the microwave radar detection module 3, and the control signal input of the output power management module 4 is connected to the control signal output. When the control signal output point of the microwave radar detection module 3 outputs the corresponding control signal, the control signal input point of the output power management module 4 is powered and begins operation, and the positive and negative power outputs of the output power management module 4 begin to output electrical energy to the load device.

[0025] The microwave radar detection module 3 has a capacitor that adjusts the duration of its control signal output. By varying the capacitance value, the operating time of the load device can be controlled. The radar has a front and back side, with the front side providing a longer detection range and the back side providing a slightly shorter range. When no one is moving near the vehicle, the microwave radar detection module enters standby mode, where power consumption is extremely low. When someone is moving near the vehicle, the microwave radar detection module enters active mode, where power consumption is primarily determined by the load device's power consumption.

[0026] In this application, the output power management module 4 can be connected to one or more output devices.

[0027] The low-cost and low-power self-assembled sentinel control system for automobiles in this application has the following advantages over traditional sentinel monitoring systems: all modules of the entire sentinel control equipment are mature products, with no development costs, and a set of control system equipment costs less than 10 yuan; it can help solve the problem of vehicle collisions caused by parking in complex parking lots today and safeguard its own legitimate rights and interests; all modules are mature products, and the entire set of control equipment has extremely low standby power consumption, the equipment is simple, and does not require additional control software; it can reuse users' discarded mobile phones to promote the development of environmental protection; users can customize the type, location and quantity of load equipment, and can connect recording equipment or connect to use alarm devices.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
