Embodiment Construction
[0029] Combine below Figure 1 to Figure 3 Shown, the present invention is described in further detail.
[0030] Such as figure 1 As shown, this embodiment discloses a semi-automatic blocking interlock logic implementation method based on a state diagram, including the following steps S1 to S2:
[0031] S1. The departure station module performs the state transition at the departure station according to the blocking operation command sent by the human-computer interaction device M at the departure station and the state transition signal sent by the pick-up station module;
[0032] S2. The pick-up station module performs state transition at the pick-up station end according to the blocking operation command sent by the human-computer interaction device N at the pick-up station end and the state transition signal sent by the departure station module.
[0033] It should be noted that the departure station module and the pick-up station module here have built-in computer interloc...

The invention discloses a semi-automatic blocking interlocking logic realization method based on a state diagram mode, which belongs to the technical field of computer interlocking. The state transition signal of the departure station performs the state transition of the departure station; the pick-up station module performs the state transition of the departure station according to the blocking operation command sent by the human-computer interaction device N at the pick-up station and the state transition signal sent by the departure station module. The present invention takes the various states in the execution process of the blocking equipment as the starting point, divides the various states into the state of the starting end and the state of the receiving end, replaces the traditional function of the relay as the starting point to realize the semi-automatic blocking and interlocking logic, and avoids the The complex process of realizing the relay function in the software reduces the coupling degree between various modules in the software realization process, and improves the reliability and maintainability of the computer interlocking system.
Description
technical field [0001] The invention relates to the technical field of railway signal computer interlocking, in particular to a semi-automatic blocking interlocking logic implementation method based on a state diagram. Background technique [0002] According to the scope of operation, the railway line can be roughly divided into two parts, one part is the station, and the other part is the section. In order to ensure the safety of railway transportation and improve transportation efficiency, safe and reliable control equipment must be installed at each station and section to realize the operation control of trains or trains. The control in the station is called interlocking, and the control in the section is called interlocking. called occlusion. [0003] Among them, the railway line is divided into several sections with the station (or line station) as the dividing point. Trains must obtain permission to enter the section, and occupy the section according to the certifica...
