Problems solved by technology
However, the cost of retrofitting computer interlocking equipment and relay circuits on existing single-track ordinary-speed railway stations to achieve automatic blockade is high
[0006] At present, there are still a large number of single-track ordinary-speed railways in China. In order to give full play to the transportation capacity of ordinary-speed railway lines, my country is working on developing a new type of mobile block system based on satellite positioning. The inter-station blocking method cannot be well combined with the mobile blocking system, and the cost of transforming into an interval four-wire automatic blocking circuit is relatively high

The invention relates to a semi-automatic block and automatic block switching design method based on computer interlocking. The method comprises the following steps: 1) switching logic design of semi-automatic block and automatic block; 2) change design of semi-automatic block logic; (3) designing an interval resquare logic in an automatic blocking mode; and 4) performing man-machine interaction design of two blocking modes. Compared with the prior art, the system has the advantages of being lower in manufacturing cost, lower in maintenance cost, higher in automation degree, higher in compatibility and applicability and the like.
Description
technical field [0001] The invention relates to a train signal control system, in particular to a design method for switching between semi-automatic blocking and automatic blocking based on computer interlocking. Background technique [0002] In my country's railway system, the interval blocking methods adopted for many years include: telephone blocking, semi-automatic blocking, automatic inter-station blocking, and automatic blocking. Among them, semi-automatic blocking and automatic inter-station blocking are mostly applied to single-track railway stations. Semi-automatic blocking refers to dividing the railway line between two stations into a section, and stipulates that only one train can run in the section. After the station handles the section blocking , Use the station's exit signal to open as a certificate for train departure. The whole section block handling process is carried out by the staff on duty at the two stations through manual confirmation. After the train...
