Embodiment 1

[0035] Such as figure 1 As shown, figure 1 It is the overall structure diagram of the multifunctional drive module of the present invention. The multifunctional drive module is provided with an output interface and an input interface, and a test circuit module, a functional logic circuit module and an output voting circuit module are arranged inside. The output interface and the input interface are hard-wired, and the signal types are digital signals. The input interface includes a control signal input interface and a test signal input interface. The signals connected to the control signal input interface and the test signal input interface include DCS or PLC respectively. Control signal and test device signal, each interface includes ON and OFF two lines, DCS or PLC control signals are processed by isolation electronic components (such as optocouplers). The signal of the drive device uses electronic components such as relays or MOSFETs to achieve "dry contact" output. For sing...

Abstract

The invention discloses a multifunctional driving module, and relates to the field of nuclear power plants. The multifunctional driving module comprises an input interface and an output interface; a testing circuit module, a functional logic circuit module and an output voting circuit module are arranged in the driving module; and the input interface comprises a control signal input interface anda testing signal input interface. The driving module employs programmable hardware (such as a CPLD (Complex Programmable Logic Device) or an FPGA (Field Programmable Gate Array) chip) to design the functional logic circuit, and the internal logic can be compiled according to the practical use, for example, the redundant voting (such as AND or NOT) logic and the priority processing logic for a received control signal are realized. The driving module is designed by a hardware circuit without operating software, and is high in reliability; and all the interfaces are in the form of hard wiring and can undergo interface application with automatic control platforms such as DCS (Distributed Control System), PLC (Programmable logic controller), etc.

Description

Technical field [0001] The invention relates to the field of automatic control, in particular to a drive module used for logic judgment of control signals in a nuclear power plant control system. Background technique [0002] In the application of operating nuclear power plants, the driving devices of various equipment are still based on traditional analog devices, which are not only bulky, but also weak. With the development of hardware technology, the calculation of complex logic can be realized through highly integrated programmable hardware technology, which greatly reduces the hardware scale and can be designed as a board or small module. The emergence of microprocessors makes it more integrated and smaller, and can achieve more complex functions, but it needs to run software, so there is a problem that reliability is not easy to verify, and there is a risk of software common mode failure . [0003] In new nuclear power plants, although modular drive devices have appeared, t...
