Abstract

The invention provides an information publishing method and device, an ISCS and a PIS. The method comprises the steps that the ISCS obtains predefined information to be published; the ISCS determinesa to-be-published information number corresponding to the to-be-published information by utilizing a first information table stored in the ISCS; and the ISCS sends the serial number of the informationto be published to the PIS, the PIS determines the information to be published according to the serial number of the information to be published and a second information table stored in the PIS, thePIS publishes the information to be published, and the contents of the first information table and the second information table are consistent. According to the scheme, the information table with theconsistent content is stored in the ISCS and the PIS, when the information is published, the ISCS sends the to-be-published information number indicating the predefined to-be-published information tothe PIS, and the PIS determines and publishes the predefined to-be-published information according to the to-be-published information number. And the ISCS transmits the information to the PIS throughthe serial number, so that the information transmission efficiency is improved, and the reliability and the transmission security are improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an information release method, an ISCS, a PIS and a device. Background technique [0002] In the actual operation of urban rail transit, various information is provided to passengers through Passenger Information System (PIS), and the information provided by PIS to passengers is provided by Integrated Supervision and Control System (ISCS) of urban rail transit. [0003] ISCS uses the function code 16 of the Modbus TCP protocol to send the information to be released to the PIS, and then the PIS releases the information to the passengers. But on the one hand, the function code 16 of the Modbus TCP protocol can only transmit information of up to 120 characters at a time. When the information to be released exceeds 120 characters, multiple interactions between ISCS and PIS are required, resulting in low efficiency and reliability of information transmission. Low. On the othe...
