And the intermediate conversion module converts the equipment state of each signal equipment into a corresponding graphic element display characteristic value.

A method for dynamically controlling a multi-standard railway signal display graphical symbol device, the method comprising the steps of:

step S1: the signal information processing module periodically calculates the equipment state of each signal equipment and sends the equipment state to the intermediate conversion module;

step S2: each signal device has a corresponding signal device identifier, the intermediate conversion module searches for a corresponding display symbol identifier according to the signal device identifier, if the display symbol identifier is not found, the signal device does not need to be displayed, and the step S5 is executed; if the data is found, the step S3 is executed;

step S3: for each display symbol mark, calculating a graphic element display characteristic value of the signal state according to the configured calculation mask, placing the graphic element display characteristic value into a sending queue of the signal equipment, and entering the step S4;

step S4: all the primitive display characteristic values in the sending queue of the signal equipment are sent to a signal display module in sequence, and the signal display module displays specific graphs on a screen according to the primitive display characteristic values; proceeding to step S5;

step S5: the one-time conversion algorithm is finished and waits for receiving the signal state of the next signal device.

A step SA is further arranged between the steps S1 and S2:

step SA: after receiving the device state of a signal device, the intermediate conversion module searches for the device state of the internal cache, and if the two states are the same, it indicates that the device state is not changed, and then the process goes to step S5; if not, the process proceeds to step S2.

A step SB is further arranged between the steps S3 and S4:

step SB: inquiring whether priority configuration exists in each primitive display characteristic value, if not, directly entering step S4; if the priority exists, the primitive display characteristic values in the sending queue are sorted from small to large according to the priority, and then the step S4 is performed.

Compared with the prior art, the invention has the following advantages:

(1) the coupling of the software functional modules is low. In the method, a three-layer software architecture is designed, the signal information processing module and the signal information display module are separated, and when the function of one module is changed, other modules are not required to be influenced.

(2) The engineering implementation cost is reduced, and the user confirmation process is accelerated. The intermediate conversion module in the method uses a manually configurable signal device state conversion configuration file to correspond each device state of a class of devices to a plurality of primitive display feature values. When the user demand shows that the details are changed, the engineering personnel can directly modify the configuration file to meet the user demand.

(3) Software development and maintenance costs are reduced. According to the method, the driving interface of the signal information display module uses the graphic primitive to display the characteristic value, and the concept of signal equipment is isolated. Therefore, when signal equipment systems of different countries or different regions are different, the configuration file can be modified, so that the intermediate module drives different display primitives, and the product requirements can be met.
