Description
Technical Field
The invention relates to the field of centralized control management, in particular to a centralized control receiving system and a receiving method thereof.
Background
The industrial monitor is used as a display terminal in occasions such as buildings, stations and the like, wherein the occasions are large in number of terminals and scattered in positions, the industrial monitor needs to be controlled by a centralized control system, can receive instructions of the centralized control system, can make correct execution actions, and simultaneously returns data meeting requirements to the centralized control system, so that a main control end of the centralized control system can collect correct terminal data to realize closed-loop control.
The monitor used in such an application needs to be able to support the standby mode and the power requirement during standby is less than 0.3W (i.e. smaller standby power is better for achieving the effect of saving energy) in the mandatory authentication requirements such as energy efficiency, etc., because the display terminal has a network function (which needs to receive TCP/IP data), and needs to support the network mode and requires less than 2W in the network mode (i.e. smaller power is better for achieving the effect of saving energy while achieving the standby function of the network), and the monitor can be controlled to switch between the standby mode, the network mode and the normal operation mode. In the standby mode, it is necessary to wake up the device via the network and recognize ID information of each display terminal.
Generally, the communication of the closed-loop control system is transmitted through a TCP/IP network, and meanwhile, the terminal device is required to support a special protocol such as creston, AMX, and the like. Such proprietary protocols are often difficult and time consuming to develop and need to be redeveloped for different chip platforms.
Therefore, for the above defects, in the existing scheme, an audio/video processing chip (such as a main chip of a TV, monitor, etc.) is used as a processing center of audio/video data, such chip supports a standby mode and a working mode, but such chip is a non-intelligent system scheme, does not have a network function, and does not support TCP/IP transmission, and in order to implement network transmission, a module for converting a network to a general protocol (such as UART, I2C), i.e., a TCP/IP to UART module, is required to be added, so as to convert the TCP/IP protocol to a general protocol, i.e., the module is used to analyze TCP/IP data, and then the module communicates with the processing chip through a general protocol such as UART.
In such a scheme, standby mode: only the PM (power management) module in the main chip works, and only a few functions such as remote control, keys and the like can be used in the PM mode; network mode: the TCP/IP to UART module and the PM module of the main chip work, and can receive network transmission data at the moment.
However, such schemes do not fully satisfy mandatory certification requirements such as energy efficiency.
Because the network needs to be realized by a TCP/IP to UART module, the power of the module is generally large, and the module can not work in a standby mode in order to meet the power requirement of the standby mode within 0.3W. Therefore, this scheme cannot support wake-on-lan. The machine can only be woken up from the standby mode by other methods such as key pressing, remote control and the like.

Referring to fig. 1, a centralized control receiving system includes: the system comprises a
main chip601, a network
protocol switching chip602, an internet of
things module603 and a
power control switch604.
A network
protocol switching chip602, wherein a first network path is arranged between the network
protocol switching chip602 and the
main chip601;
the internet of
things module603 is provided with a second network path between the network
protocol switching chip602 and the internet of
things module603, and the material network module is used for protocol conversion in a network mode and sending the converted control data to the
main chip601;
the
power control switch604 is connected with the internet of
things module603, and is used for supplying power to the internet of
things module603 through a
power supply605;
the
main chip601 controls the
power control switch604 to be turned off and controls the network
protocol switching chip602 to switch to a first network path, and enters a standby mode; in the standby mode, the network
protocol switching chip602 receives control data sent by the main control terminal through a designated interface, and sends the control data to the
main chip601 through the first network path, and when the
main chip601 receives wakeup data, the network
protocol switching chip602 is controlled to switch to the second network path, and the
power control switch604 is controlled to be turned on, so as to enter the network mode.
In this embodiment, the
main chip601 can enter the standby mode by controlling the
power control switch604 and the network
protocol switching chip602, and the specific control steps are as follows:
the
main chip601 controls the
power control switch604 to be turned off, the internet of
things module603 turns off the power to stop working, and the
main chip601 controls the network
protocol switching chip602 to switch to the first network path.
The
main chip601 may be an audio/video processing chip with a network function and a standby mode supporting a wol (wake on lan) function, so that in the standby mode, the PM module of the
main chip601 may directly receive wakeup data from the main control end without protocol conversion.
After entering the standby mode, except for the PM module, other modules in the
main chip601 are all in sleep, and meanwhile, the network
protocol switching chip602 is also in a working state under the power supply of the
power supply605, because the power consumption of the network
protocol switching chip602 is extremely low, the power consumption required by the operation of the PM module of the
main chip601 and the network
protocol switching chip602 in the standby mode still meets the energy efficiency requirement of low power consumption (for example, less than 0.3W).
The first network path is a network path between the network
protocol switching chip602 and the
main chip601, and in the standby mode, control data sent from the main control terminal to the network
protocol switching chip602 is transmitted from the first network path to the
main chip601, and only wakeup data in the control data can be recognized by the
main chip601 and the
main chip601 enters the network mode.
The working PM module can receive control data received and transmitted from the designated interface by the network
protocol switching chip602 in real time, and when receiving wakeup data, the
main chip601 will perform corresponding action of waking up the system to enter a network mode, and the specific control steps are as follows:
the
main chip601 controls the
power control switch604 to be turned on, the internet of
things module603 is powered on and works, and the
main chip601 controls the network
protocol switching chip602 to be switched to the second network path.
After entering the network mode, only the PM module in the
main chip601 still maintains working, the network
protocol switching chip602 and the internet of
things module603 are in a power supply state and also in a working state, and power consumption required by the PM module, the network protocol switching module and the internet of
things module603 at this time meets the energy efficiency requirement of low power consumption (for example, less than 2W).
The second network path is a network path between the network
protocol switching chip602 and the internet of
things module603, in the network mode, control data sent from the main control end to the network
protocol switching chip602 is transmitted from the second network path to the
main chip601, only a power-on instruction and an ID reading instruction in the control data can be identified by the
main chip601, when the power-on instruction is received, the
main chip601 performs a corresponding action of starting the system, and when the ID reading instruction is received, the
main chip601 performs a corresponding action of returning the ID information of the system.
Specifically, since the
main chip601 cannot directly analyze the control data in the TCP/IP protocol, before the control data sent from the main control end enters the
main chip601 through the second network path, the protocol conversion operation is performed on the protocol carrying the control data through the internet of
things module603, and the analyzed control instruction is sent to the
main chip601.
Specifically, the protocol conversion action is that the internet of
things module603 converts the TCP/IP protocol into a specific protocol (i.e., a specific general protocol) supported by the
main chip601.
Specifically, the operation of starting the system includes that other modules in the
main chip601 except the PM module also enter the working state.
Specifically, the corresponding action of returning the ID information of the system includes that the
main chip601 sends the ID information to the internet of
things module603, the internet of
things module603 performs protocol conversion to obtain an ID result, and then the internet of
things module603 enters the network
protocol switching chip602 through a second network path and transmits the ID result back to the main control end through a designated interface.
After the ID information is read, the main control end can add the ID information into the subsequently sent control instruction as an address and selectively send the control instruction.
In one embodiment, the
main chip601 controls the
power control switch604 to be turned on and off through a first GPIO, and the
main chip601 controls the network
protocol switching chip602 to switch between the first network path and the second network path through a second GPIO.
Specifically, the first GPIO and the second GPIO are PIN PINs that are controllable in the standby mode on the
main chip601.
When entering the standby mode, the
main chip601 controls the
power control switch604 to be turned off by controlling the first GPIO, so that the internet of
things module603 is powered off, and controls the network
protocol switching chip602 to be switched to the first network path by controlling the second GPIO, and at this time, only the network
protocol switching chip602 and the PM module in the
main chip601 work.
When wake-up data is received, the system enters a network mode, at this time, the
main chip601 controls the
power control switch604 to be turned on by controlling the first GPIO, so that the internet of
things module603 is powered on, and controls the network
protocol switching chip602 to be switched to a second network path by controlling the second GPIO, and at this time, the network
protocol switching chip602, the internet of
things module603 and the PM module in the
main chip601 are all in a working state, receive control data sent by the main control terminal at any time, and perform corresponding response according to the received control data.
Specifically, the designated interface is an RJ45 interface (an RJ45 interface is used for data transmission, and is generally applied to a network card interface).

In this embodiment, in the standby mode, only the PM module of the main chip and the network protocol switching chip are in the working state, and the required energy consumption meets the energy efficiency requirement of low power consumption (for example, less than 0.3W); in the network mode, in the standby mode, the wake-up data transmitted by the main control end is received by the main chip to realize network wake-up, and in the network mode, only the PM module, the network protocol switching chip and the internet of things module of the main chip are in a working state, and the required energy consumption meets the energy efficiency requirement of low power consumption (for example, less than 2W).

the main chip controls the power control switch to be turned off, the Internet of things module cuts off the power supply to stop working, and the main chip controls the network protocol switching chip to be switched to the first network path.
In this embodiment, the first predetermined time is a first preset time of an operator in the system, and may be changed according to an actual situation.

the main chip controls the power control switch to be turned off, the Internet of things module cuts off the power supply to stop working, and the main chip controls the network protocol switching chip to be switched to the first network path.
The second preset time is a second preset time of an operator in the system, and may be changed according to an actual situation.
