Detailed ways

In the invention description submitted by the applicant with the application number 03157141.7, an associating device is provided, which can be used to query the hardware status information of the device where the associating device is located, and can combine the hardware status information of the device and the Other configuration information of the device is sent to the network; the associated device can also respond to borrowing requests from other devices with associated devices in the network according to the hardware usage of its own device, and establish call links with other associated devices , release, etc.

The association monitoring system described in the present invention needs to be realized by using the association device described above, and the association device is referred to as an association module hereinafter. The technical solution of the present invention will be described in detail below.

The association monitoring system of the present invention includes association front-end equipment, association control equipment, and association back-end equipment. The associated front-end device and the associated back-end device establish an associated connection and communicate through the associated control device.

An associated front-end device refers to a front-end device provided with an associated module. The present invention sets association modules on the original front-end equipment, including cameras, loudspeakers, MIC equipment, access control switches and other equipment, and records the information of the front-end equipment by the association module, including the identification (ID) of the equipment, equipment type, location, The device group, device busy or idle working status, priority, etc. The equipment type mentioned therein refers to the category of each equipment included in a monitoring system.

An associated backend device refers to a backend device configured with an associated module. In the present invention, an association module is set on the original back-end equipment, including the display, audio input and output equipment, and control equipment, and the information of the back-end equipment is recorded by the association module, including the ID, equipment type, location, and equipment group of the equipment. , device busy or idle working status, priority, etc.

Here, the fine-grained back-end equipment is further subdivided into associated back-end display units, such as display devices such as TV display screens, computer monitors, mobile phone screens, and PDA screens with associated modules; associated back-end audio units, Including speakers, audio, MIC, etc. with associated modules; associated back-end management units, such as remote controllers, computer mouse keyboards, mobile phone keyboards, PDA keyboards, etc. equipped with associated modules. Wherein, for the equipment units that can exist independently, an independent associated module is set; for the equipment units linked on hardware, an associated module can be shared. For example, for a TV set, which itself includes the display screen of the display unit, the sound box of the audio unit, and the remote control of the management unit, these three equipment units can use an associated module. When configuring in the associated module , each equipment unit maintains its own ID, and the equipment information of its associated TV acquired by the TV association module is shown in the following table. Here, it is set that the equipment unit using one associated module is located in one equipment group.

Device ID Equipment type Location The device group where working status priority Remark 0001 A-display unit rear end TV group idle 1 display screen 0002 B-Audio unit rear end TV group idle 1 TV speakers 0003 C-Snap-in rear end TV group idle 1 remote control

Table 1

The association monitoring system of the present invention also includes an association control device, which is used to collect the information of the equipment sent by each association module of the association front-end equipment and the association back-end equipment, and select the available association front-end equipment and association back-end according to the collected information The equipment unit establishes the connection between them, and processes the transmitted data in the process of transmitting data between the associated front-end equipment and the associated back-end equipment, and converts it into a signal format recognized by the receiving equipment, such as three primary colors (RGB ) format, Phase Alternative Line (PAL) format, IP packet and other formats.

There may be several equipment units in the associated front-end equipment and associated back-end equipment included in the associated monitoring system. The realization of associated monitoring is to automatically combine one or more sets of available monitoring systems from these equipment units for users to use. The following takes an associated back-end device unit as an example to trigger the establishment of an associated connection, and with reference to the flow chart for realizing the associated monitoring shown in FIG.

Step 201: An associated back-end device triggers associated communication, and sends a system establishment trigger signal to the associated control device through its associated module. The system establishment trigger signal includes the device information of the device where the associated module is located, including: device ID, device type, location , device group, working status, and priority.

Step 202: The associated control device receives and responds to the system establishment trigger signal, records the device information carried in the system establishment trigger signal, and broadcasts a resource usage request message to other devices in the network.

Step 203: The association back-end device and the association front-end device that received the resource use request message send back a response message through their association module, and send the information of the device where the association module is located to the association control device.

Step 204: The association control device receives the response information of each associated device, and updates the recorded associated device information configuration table. The configuration table can refer to the following table 2 as shown:

Device ID Equipment type Location The device group where working status priority Remark 0001 A-display unit rear end TV group idle 1 display screen 0002 B-Audio unit rear end TV group idle 1 TV speakers 0003 C-Snap-in rear end TV group idle 1 remote control 0011 A-display unit rear end PC group idle 2 display screen 0012 B-Audio unit rear end PC group idle 2 PC speakers 0013 C-Snap-in rear end PC group idle 2 PC keyboard 0031 B-Audio unit rear end none idle 3 Audio 1001 D-Camera front end none idle 1 Camera 1002 E-MIC front end none idle 1 MIC

Table 2

Step 205: According to the associated equipment information configuration table, and according to the equipment types required to establish the current monitoring system, the association control equipment selects an idle equipment unit from the required and different equipment types, and then sends the selected The device sends a request to connect message.

Wherein, when the associated control device selects the equipment unit, it may select according to the priority, and preferentially select the equipment unit with higher priority. In addition, when the selected equipment belongs to a certain equipment group, when other types of equipment units are selected, they are preferentially selected from the equipment group, that is, the equipment units of the same group are preferentially selected.

In addition, after the back-end equipment information configuration table is established, the information can be displayed to the user, and the user can select the desired equipment unit.

Step 206: The associated device that receives the connection request message sends back a response message. After the associated control device receives the response message, it establishes a call connection, and the status of the corresponding associated device is changed to busy; if the associated control device does not receive the corresponding response within a certain period of time. If the response information of the associated device returns to step 205, another device of the type of device initiates a connection request.

It is not difficult to understand that the associated control device can also be pre-set to forcibly switch, interrupt other processes of the selected associated device, and respond to the connection request with the associated control device.

Step 207: After the associated control device establishes a connection with the associated front-end device and the associated back-end device, the user can communicate with the associated front-end device through the established connection on the associated back-end device, including transmitting audio, video and control signals. Wherein, the signals of the associated front-end equipment and the associated back-end equipment are relayed and signal format converted by the associated control equipment.

When the associated control equipment performs signal conversion, since the front-end or back-end equipment may integrate multiple associated equipment units, that is, multiple associated units belong to a working group, such as a TV including a display unit and an audio unit, sharing an associated module , In a working group, at this time, the audio/video signal is converted into a corresponding PAL TV signal and sent to the TV. Another example is that a computer is also a device including a display unit and an audio unit, and shares an associated module. At this time, the audio/video signal is converted into a corresponding multimedia stream and sent to the computer.

After the connection with the back-end control device has been established, the user can control through the associated back-end management unit, and control the associated front-end device to switch with other front-end devices. At this time, the switched object establishes a connection with the associated control device according to the above steps ; It is also possible to establish another multiple sets of front-end and back-end device connections with the associated control device according to the above steps for communication. That is to say, after a set of related monitoring system is automatically established, the user can arbitrarily select or switch front-end and back-end equipment according to needs, or re-establish the connection of multiple sets of front-end and back-end equipment, so as to realize the connection between the front-end equipment and the back-end equipment. One-to-many, many-to-one, and many-to-many connection communication methods for devices.

Wherein, the one-to-many and many-to-one modes described above can be regarded as a set of associated monitoring systems. For a set of associated monitoring systems in the form of one-to-many or many-to-one, for example, the collected information of the same front-end device is displayed on multiple back-end display devices at the same time, and audio is played on multiple back-end audio devices at the same time; or, The same back-end device displays the video information collected by multiple front-end devices at the same time. It is only necessary for the user to pre-set the back-end display device on the associated control device to use split screens to achieve multi-screen display, and then the associated monitoring system can be established at the beginning. Of course, after establishing a one-to-one associated monitoring system, it can also be set through the associated control device, and adjusted to this associated form by initiating a connection.

The many-to-many mode described therein means that other monitoring channels are repeatedly established to become another monitoring system, forming multiple sets of related monitoring systems. Among them, it can be pre-set to implement multiple sets of modes when it is established. Among them, besides automatic completion, the establishment process can also be participated by the user. The required front-end and back-end devices are selected through the associated back-end management unit, and the associated control device sends a connection request message to the selected device to establish a corresponding connection.

Step 208: When the user needs to end the monitoring, such as pressing a preset specific button on the remote control, the associated back-end management unit sends a service termination request message to the associated control device, and the associated control device sends a message to the current Each associated device of the established connection broadcasts a service termination message, and releases the occupied associated device resources.

Step 209: After the associated front-end device and the associated back-end device receive the service termination message, release the connection, and restore the state of the device to the initial state.

The above process is explained by taking the triggering of the associated back-end module as an example. It is also applicable to the monitoring association process triggered by the associated front-end equipment. For example, the doorbell device is designed as a trigger device. When the user presses the doorbell, the doorbell device sends a message to the associated control device. The trigger signal activates the monitoring association process.

It is not difficult to understand that the associated control device can also periodically send query messages to each associated device unit to record the information and working status of each associated device. In this way, after a certain associated device unit triggers the connection, the associated control device can immediately use the recorded Information is associated and selected, and step 205 is executed to shorten the time for establishing a connection. However, due to the need for regular query and regular sending of information to the network, more system resources and network resources will be occupied. Users can choose different methods according to their needs.

In addition, the user can also set the association control device to automatically initiate the establishment of the connection, that is, the system establishment trigger signal is generated by the association control device itself, for example, it is preset to be automatically triggered at a fixed time. In this case, after the association control device is automatically triggered, it broadcasts a resource use request message to other devices in the network, and then executes steps 203 to 209 to realize the establishment of an association monitoring system. Or as mentioned in the previous paragraph, according to the information of the front-end and back-end equipment that has been recorded by itself, the association control device immediately performs association selection according to the recorded information, and performs steps 205 to 209 to realize the establishment of an association monitoring system.

Fig. 3 shows a schematic diagram of an associated monitoring system applied to an access control system. In this figure, the associated front-end equipment includes: a camera with an associated module, MIC, which is connected to the associated control device through a wired method, and the associated back-end equipment includes: a TV with an associated module, and a personal computer (PC).

Taking the access control system as an example, and referring to the flow chart of the implementation of the monitoring association of the access control system shown in FIG. 4 , the method will be further described in detail.

Steps 401-402: The visitor presses the doorbell, and the doorbell device transmits the pressing information to the associated control device, triggering the association process, and the associated control device broadcasts a resource usage request message to the network where it is located.

Step 403: The associated equipment unit that receives the resource use request message sends its equipment information to the associated control device through the association module.

Step 404: The associated control device receives the information reported by each associated device unit, and updates the associated device information configuration table.

Step 405: According to the associated device information configuration table, the associated control device selects an associated device that is in an idle state and has a high priority from each required device type, and preferentially selects the device units of the same device group, and then sends the selected The device sends a request to connect message. In this example, assuming that the device information configuration table of the associated control device stores the contents in Table 2, select the TV as the associated back-end device, and select the camera and MIC as the associated front-end device.

Step 406: After receiving the connection request message, the associated equipment unit sends back a response message, and after receiving the response message, the associated control device establishes a connection with the associated equipment unit.

Step 407: After the connection is established, the user can use the established connection to communicate with the associated camera and MIC through the associated TV, and the associated control device converts the signal format, converts the front-end signal into a PAL signal and transmits it to the TV for display.

Steps 408-409: When the call is over, the user can use the preset button of the TV remote control to stop the service, or select the stop service option on the TV screen through the remote control, and the TV association module will send a service termination request message to the associated control For equipment, the associated control device sends a service suspension message to the connected equipment unit. After receiving the command, the associated device unit terminates the current application operation and restores to the initial state. The associated control device releases the occupied resources.

Through the above correlation monitoring system and the monitoring correlation implementation method provided, the user can monitor in different places.
