Problems solved by technology
[0002] With the development of science and technology, intelligent control is adopted in many fields. Intelligent control is inseparable from status monitoring, data transmission and action execution, such as smart home, water level detection, power supply system, etc. With the application of intelligent control systems more and more Extensive, the control system is becoming more and more complex, the probability of failure of the control system is increasing, and the difficulty of fault diagnosis is increasing, and the requirements for maintenance personnel are getting higher and higher
When a fault occurs, maintenance is often interrupted, resulting in system failure
[0003] Some existing control systems, in order to prevent failures, often rely on the experience of technicians, and replace them as a whole when they need to be replaced. , often leads to the replacement of many components that do not need to be replaced, resulting in a lot of waste

Embodiment 1
[0033] See Figure 1-2 As shown, for a control system, first disassemble the system into components, such as sensor 1, repeater 2, first controller 3, actuator 4..., where sensor 1 is connected to repeater 2, The repeater 2 is connected to the first controller 3, the first controller 3 is connected to the actuator 4, and the sensor 1 detects the status of the actuator 4. The sensor 1 can transmit the signal to the repeater 2 in real time, and the repeater 2 every interval T transmits the signal to the first controller 3, and the first controller 3 controls the action of the actuator 4 according to the received result, and the sensor 1 continuously detects the state of the actuator 4. In this process, the loss of each element is different, and the loss of each element interacting with different elements is also different. For example, the loss of the actuator 4 and the first controller 3 is greater than that of the sensor 1.
[0034] It can be understood that in practical applicat...

The invention relates to a control system diagnosis method based on a complex dynamic network. The method comprises the following steps that a network model of a control system is established; each component in the control system transmits a current operating state to a remote system in time, and the operating probability of each monitored component in the respective state is determined accordingto the real-time operating state of each component; whether or not there is a potential fault is determined according to the operating probability; the component with the potential fault is repaired and replaced. By adopting the technical scheme, component failures can be effectively evaluated and prevented, the failures are prevented correspondingly, and the cost is reduced.
Description
Technical field [0001] The invention relates to the field of monitoring technology, in particular to a control system diagnosis method based on a complex dynamic network. Background technique [0002] With the development of science and technology, intelligent control is adopted in many fields. Intelligent control is inseparable from state monitoring, data transmission and action execution, such as smart home, water level detection, power supply system, etc., as the application of intelligent control systems is increasing Widespread, the control system is becoming more and more complex, the probability of the control system failure is increasing, and the difficulty of fault diagnosis is increasing, and the requirements for maintenance personnel are getting higher and higher. Repairing when a fault occurs often interrupts a lot of work and leads to system failure. [0003] Existing control systems, in order to prevent failures, are often based on the experience of technicians, and ...
