[0002] Launch vehicles are a crucial component of air defense weapon systems, involving multiple complex branches such as launch control systems, launcher servo control systems, and vehicle power supply and distribution systems. Among these, optocouplers, as an important means of detecting electrical signals, are widely used in various aspects, including launch timing detection, launcher limit detection, motor driver status detection, and power supply and distribution control detection. However, optocouplers often require different matching designs for different detection scenarios; furthermore, depending on the different control signals required after detection, optocouplers typically need to be paired with specific drive execution control circuits. This results in launch vehicles requiring multiple independent and separate optocoupler detection and control modules to achieve the relevant detection and execution control functions under different scenarios, leading to design redundancy and high costs.

[0077] Example 2

[0078] Example 2 is a preferred example of Example 1.

[0079] Reference Figure 1 This invention provides a universal optocoupler circuit integrated control device, comprising:

[0080] The communication control board controls the operation of the entire general-purpose optocoupler integrated control module: it receives command messages from the host computer via CAN communication, controls the drive execution board to output control signals with load capacity via I / O signals, receives I / O signals transmitted from the optocoupler board, and sends electrical signal acquisition information to the host computer via CAN communication. In this case, the communication control board includes a DSP processor and a CAN communication driver circuit. The CAN communication driver circuit uses a TD501DCAN driver chip with built-in electrical isolation to complete the mutual conversion between CAN signal level and CMOS level; the DSP processor uses a TMS320F28335 model to receive the converted CAN signal and expands the DSP's inherent GPIO channels through an FPGA circuit to complete I / O signal interaction.

[0081] The optocoupler board controls the acquisition of external electrical signals and converts them into I / O signals with CMOS level attributes required by the DSP processor. In this case, the optocoupler board integrates different types of optocoupler sampling circuits for electrical input signals (such as power supply and ignition signals) from the transmitter vehicle (12V, 24V, 36V, 48V, etc.) to complete the level conversion of the input signals, converting them into CMOS levels suitable for the DSP controller for digital sampling, while also protecting the communication control board.

[0082] The drive execution board controls the output of electrical control signals with different load capabilities; simultaneously, it receives external power and converts it to supply power to the communication control board and optocoupler board. In this case, the drive execution board integrates a power supply interface circuit and an opto-MOS control circuit; the general optocoupler circuit integrates a control module powered by a 24V external power supply. The power supply interface circuit uses multi-specification DC / DC modules to convert the external 24V power supply to 3.3V and 5V to supply power to the communication control board and optocoupler board. Simultaneously, it works with the opto-MOS control circuit to provide power at levels of 24V, 55V, and 70V. The opto-MOS control circuit receives I / O signals from the communication control board and, through multi-specification opto-MOS solid-state relays, provides electrical control signals with different load capabilities, such as 2A / ±24V, 1A / ±55V, and 0.5A / ±70V.
