Background technique

In recent years, there have been many kinds of display devices used in the home, common ones include video door intercom devices, digital photo frames, large-screen calendar clocks, video surveillance equipment, etc. These display devices provide a lot of convenience and fun for our lives , to make our life better. At present, these devices and devices exist independently and need to be purchased, installed and wired separately. However, they often do not need to be used at the same time, so a multifunctional wireless transmission display scheme can be used to realize the functions of multiple display devices in combination.

Contents of the invention

The purpose of this utility model is to provide a low-cost family multifunctional wireless display monitoring system that mainly uses wireless transmission and integrates multiple functions such as digital photo frame, video door intercom, video monitoring, calendar clock and family information display.

The utility model is realized by adopting the following scheme: a family multifunctional wireless display monitoring system, which is characterized in that it includes an intelligent terminal for color graphics display, man-machine dialogue, data storage management, communication management and system control. The terminal communicates with several monitoring cameras used for image acquisition via the Bluetooth communication module.

The utility model integrates multiple functions such as digital photo frame, video door intercom, video monitoring equipment, calendar clock and family information display. Since these functions generally do not need to be used at the same time, it can reduce the cost of the equipment without affecting the use. Quantity, reduces the cost of use, and also reduces the consumption of non-renewable resources. Using bluetooth wireless transmission technology to transmit images and other information has the advantages of no additional wiring for installation and no damage to decoration, making it easy for ordinary families to accept.

Detailed ways

Below in conjunction with accompanying drawing and embodiment example the utility model is described further.

As shown in Figure 1, the utility model provides a family multifunctional wireless display monitoring system, which is characterized in that it includes an intelligent terminal for color graphic display, man-machine dialogue, data storage management, communication management and system control, the The intelligent terminal communicates with several monitoring cameras for image acquisition via the Bluetooth communication module.

Please refer to Figure 2, Figure 2 is a hardware block diagram of an intelligent terminal, the intelligent terminal is an independent component, consisting of a first ARM processor and a Flash memory connected to the first ARM processor, SDRAM, touch screen, Bluetooth network module, Ethernet interface, Composed of SD card interface and USB interface.

In this implementation example, the smart terminal is composed of an ARM processor, a built-in or external 512K byte NOR Flash memory, a 32M byte SDRAM for data and display storage, and no less than 64M byte NAND Flash memory used as a solid state disk , TFT LCD with a resolution above VGA standard, a four-wire resistive touch screen that matches the size of the LCD, a touch screen controller, a Bluetooth network module, an Ethernet interface, an SD card interface and a USB interface. The smart terminal is powered by AC power and backup batteries, with AC power as the main power. There is a small-capacity backup battery inside to maintain the operation of the calendar clock in case of power failure. The smart terminal uses a real-time operating system, and its core content is the task scheduling module, which sets the task queue and defines the priority of the task. All tasks generated when the program is running must be applied for, and the resource is allocated by the task scheduling module. High-priority tasks can be preemptively run by interrupting low-priority tasks. Tasks with the same priority enter the task queue and execute according to the principle of first-in-first-out. Tasks that run overtime are terminated by the operating system and resources are recovered.

Please refer to Fig. 3, Fig. 3 is the hardware block diagram of monitoring camera, and this monitoring camera is an independent component, is made up of the second ARM processor and the SRAM connected with this second ARM processor, image sensor, coding chip and bluetooth communication module .

In this implementation example, the surveillance camera is composed of an ARM processor as the core, configured with 256K bytes of SRAM, an image sensor of the OV76xx series, an encoding chip ZR36060 (optional) and a Bluetooth network module. The surveillance camera is powered by a rechargeable battery, or it can be powered by an AC power supply through power adapter.

After the smart terminal is powered on, the ARM processor runs the main program as shown in Figure 4. First, it initializes the software and hardware of the smart terminal, searches for the Bluetooth network, establishes the Bluetooth connection and the Bluetooth network registry, and starts various required interrupts. Enter the task scheduling management module, and automatically complete the scheduled tasks according to the preset working mode. The tasks performed by the smart terminal are generated by various interrupts. The main interrupts and the generated tasks are: timer interrupt, as shown in Figure 5, mainly generates various timing tasks, including image refresh in digital photo frame mode and switching, image refresh and camera command in video surveillance mode, Bluetooth network status refresh, various time-related preset tasks, system task management and environmental monitoring detection, etc.; touch screen interruption, as shown in Figure 6 It is used to identify touch screen operations, and set various human-computer interaction tasks according to the results of human-computer interaction; Bluetooth communication interruption, as shown in Figure 7, is used to realize Bluetooth communication, and generate storage tasks as needed when Bluetooth communication ends and graphics refresh switching tasks; Ethernet interrupt, as shown in Figure 8, is used to realize Internet communication, and various Internet communication tasks generated according to communication messages.

After the surveillance camera is powered on, the ARM processor runs the main program as shown in Figure 9. First, it initializes the software and hardware, searches for the Bluetooth network, establishes the Bluetooth connection and the Bluetooth network registry, starts various required interrupts, and then enters the dormant state. . The ARM processor of the surveillance camera can be woken up by the built-in timer interrupt that can be programmed according to the flow shown in Figure 10, and can also be woken up by the bluetooth communication interrupt designed according to the flow shown in Figure 11. After waking up, the ARM processor automatically tests the hardware system and queries the set tasks. If there is a scheduled automatic transmission task or a camera command sent by the smart terminal through the Bluetooth network, the surveillance camera will start the image sensor to take pictures, and the decoding chip or After being compressed by the ARM embedded processor, it is sent to the smart terminal through the Bluetooth network. After the camera task is completed, the surveillance camera enters the dormant state again. When needed, the surveillance camera can also work in the continuous shooting mode and no longer enter the dormant state. The continuous mode consumes a lot of power, so it should be powered by a large-capacity battery or an AC power supply.

The above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
