According to an embodiment of the present invention, a control system of a set top box is provided.
As shown in fig. 1, a control system of a set-top box according to an embodiment of the present invention includes: the system comprises an upper computer, a controller in communication connection with the upper computer, and a plurality of set top boxes (set top boxes 1, … set top box n) in communication connection with the controller.

By the technical scheme, all or part of the set top boxes in the multi-channel set top boxes can be controlled, and the set top boxes can be uniformly and efficiently controlled.
The controller can be implemented by a programmable embedded system, such as a single chip microcomputer or other programmable controllers. Alternatively, the controller may employ an STM32 series chip as the main control chip. The STM32 series is based on a high-performance, low-cost, low-power ARM Cortex-M3 core, and the clock frequency of the F103 series can reach 72 MHz.
The controller can be divided into a core board and an expansion board. The core board is connected with the expansion board through the slots on the expansion board, so that complete electrical connection is guaranteed. The core plate is welded with an STM32 chip, and is also provided with a power indicator light and a reset key so as to be convenient for users to use.
As shown in fig. 1, in one embodiment, the controller includes: an input port IN1 for receiving control commands; and a plurality of output ports (OUT1, … OUT n) corresponding respectively to the plurality of set-top boxes (set-top box 1, … set-top box n), each output port (OUT1, … OUT n) for transmitting signals to a corresponding set-top box (set-top box 1, … set-top box n). Specifically, an interface conversion module for converting a USB interface into a serial interface may be provided on the controller as the input port IN1, and the interface conversion module may be used for supplying power to the controller and communicating data with the upper computer.
Optionally, the number of the set-top boxes may be 16, and since the control command for the set-top boxes is generally an infrared signal, 8 infrared emission heads with a wavelength of 940nm may be respectively arranged on the left and right sides of the controller as a plurality of output ports (OUT1, … OUT n), and the STM32 chip of the controller sends the control command to the set-top boxes through the infrared emission heads corresponding to the corresponding I/O ports.
In one embodiment, the remote control device further comprises a remote controller for sending a remote control command according to the requirement; wherein, the controller includes: and the input module is used for receiving a remote control command. Specifically, an infrared receiving head (for example, an infrared receiving head model VS 1838B) may be provided on the controller as an input module for receiving a remote control signal transmitted by the remote controller.
Furthermore, 16 paths of I/O ports in the STM32 chip can be connected with the 16 infrared emission heads and used for carrying out infrared emission on control instructions sent by the I/O ports, and the STM32 chip can support the connection and disconnection of a single I/O port and multiple I/O ports; in addition, the 1-way input mode I/O port in the STM32 chip may be connected to the infrared receiving head for receiving remote control signals.
The initialization process of the controller comprises the following steps: after the controller is powered on for a few clock cycles, the program in the controller starts to initialize each module, including clock initialization, initialization of I/O ports of the STM32 chip, and initialization of interrupts. The clock frequency is 72MHz, so that the processing speed can be ensured to be fast and stable. The controller of the invention uses the specific NVIC interrupt of the STM32 chip to divide the interrupt into three types of serial port interrupt, timer interrupt and external interrupt. The serial port interrupt is used for data communication with an upper computer, the timer interrupt is used for generating a 38KHz carrier signal necessary for infrared signal communication, and the external interrupt is used for receiving an infrared remote control signal transmitted by an external remote controller. After the initialization is finished, the controller enters a standby working state, all the infrared transmitting heads are in a closed state at the moment, and the infrared receiving heads are in an open state.
In one embodiment, the control instructions include: a port selection instruction; the upper computer is used for sending a port selection instruction.
In one embodiment, the controller is configured to verify the port selection instruction and control, according to a verification result, an output port corresponding to the set top box to be controlled from among the plurality of output ports to be opened.
In one embodiment, the control instructions further comprise: transmitting an instruction; the upper computer is also used for sending a transmitting instruction; and the controller sends a transmitting instruction to the corresponding set top box to be controlled through the opened output port.
In one embodiment, the controller sends a remote control command to the corresponding set top box to be controlled through the opened output port.
The above embodiment is explained below in conjunction with a specific control process of the controller. The control process of the controller can be divided into two working modes of upper computer control and remote control.
Under the upper computer control mode: after the host computer sends a port selection instruction, the host computer sends the port selection instruction to an STM32 chip IN the controller through an input port IN1, serial port interruption of the STM32 chip is triggered at the moment, comprehensive verification can be performed on a received port selection instruction including a header code, a function code, a content code and a check code IN the serial port interruption, and if a verification result meets the coding requirement, corresponding output ports (such as OUT1 and OUT n) are opened according to the requirements of the function code and the content code. After the output ports OUT1 and OUT n are opened, the upper computer sends a transmitting instruction to be transmitted to the STM32 chip, and after the STM32 chip identifies the function code and the content code of the transmitting instruction, the infrared signal conforming to the infrared communication protocol is sent OUT through the opened output ports OUT1 and OUT n.
In the remote control mode, a tester can conveniently control the set top box without passing through the upper computer, and before the remote control mode is used, the upper computer is required to send a port selection instruction to open a corresponding port. When the remote control mode works, the infrared receiving head of VS1838B model on the controller receives the remote control signal generated by the remote controller and triggers the external interrupt of STM32 chip, the receiving code of the remote control signal is correspondingly checked in the interrupt service program, and the command code of the remote control signal is transmitted to each corresponding set-top box in the standard infrared communication mode after the check is passed.
In one embodiment, the control instructions may include: a power control instruction; and the controller controls the power supply of the set top box to be controlled according to the power supply control instruction.
