Problems solved by technology
Since the industrial computer must not only run the interlock control program, but also control the interface circuit, the number of interface circuits that can be controlled is limited, which leads to the poor scalability of the existing station equipment information detection and control system and cannot be applied. for larger stations
Secondly, the system structure level of the existing technology is not clear enough, which makes it very difficult to carry out troubleshooting and testing work, which in turn leads to low reliability of the system

The invention discloses a control system for a safe intelligent I / O composite system, which comprises an interlocking machine, a device-driving and state-acquiring circuit 1, a device-driving and state-acquiring circuit 2, a first MCU and a second MCU, wherein the first MCU and the second MCU are connected with the interlocking machine respectively through two paths CAN buses, the first MCU is also connected with the device-driving and state-acquiring circuit 1, the second MCU is also connected with the device-driving and state-acquiring circuit 2, and the first MCU is connected with the second MCU through a UART port. By using the control system as a base, the invention also provides a method for controlling the safe intelligent I / O composite system for controlling the states of devices in the safe intelligent I / O composite system and acquiring and commanding the interaction process in real time. The control system and the method can effectively ensure the accuracy of information acquisition and improve the reliability of information transmission and the safety of the system, and are mainly applied to the safe intelligent I / O composite system in the field of locomotive station track control.
Description
technical field [0001] The invention relates to a control method, in particular to a control method of a safety intelligent I / O combined system applied in the field of locomotive track control. Background technique [0002] In the field of locomotive track control, whether the status of station equipment (mainly including signal machines, track circuits, turnouts and other signal equipment) is normal or not is directly related to the operation efficiency and safety of the entire operation system. If it cannot be reliably controlled and If the abnormal situation is discovered in time, it will bury a safety hazard for the locomotive running, and may even cause a safety accident. Therefore, the information monitoring and control of the station equipment is a very important task. [0003] At present, the information detection and control of the station equipment is realized by the industrial computer that performs the interlocking operation through the corresponding interface ci...
