Problems solved by technology

[0004] The technical problem to be solved by the present invention is: to overcome the problems existing in the prior art, to provide a train network control method for PIS automatic station announcement, and the TCMS system can directly send commands to the PIS system to execute the station announcement order, which solves the problem Some PIS automatic station announcements rely heavily on the ATC signaling system, thus avoiding the problem of PIS automatic station announcement stopping when the communication between the ATC signaling system and TCMS is disturbed or completely interrupted

Embodiment 1

[0049] Such as figure 1 As shown, the device in this embodiment includes a train network system and a PIS system, and the PIS system is used to execute instructions sent by the train network system. Wherein the train network system includes a station information storage module, which is used to store the station information table, wherein the name of each station is recorded, the distance information between two adjacent stations, and the uplink operation direction and downlink operation direction of the marked train; the distance calculation module, It is used to receive the current train speed and door state information, calculate in real time according to the current train speed and door state information, and output the distance of the train from the previous station and the distance of the train to the next station to the trigger station reporting control module; the next station ID Calculation module, connected with the station information storage module, for judging acc...

Embodiment 2

[0053] The difference between this embodiment and Embodiment 1 is that the distance calculation module of the train network system adjusts the current state of the train door and the speed of the train, and calculates the current state of the train door according to formula (1) (Y=1 and V>0m / h). Judging with the running state of the train, when Y=0 and V=0, the train is stationary, and the distance calculation module is based on (3) formula (L 1 = L 2 , L 4 = 0m and L 5 = L 30 ) Calculate and output the distance L of the train leaving the last station 4 and the distance L from the train to the next station 5 ,at this time 4 and L 5 reset to the default value, which is L 1 = L 2 , so that L 4 =0,L 5 = L 3 , stop the operation, and then manually judge whether it needs to be re-operated according to the actual situation, if it is necessary to re-operate, otherwise the operation ends.

Embodiment 3

[0055] The difference between this embodiment and Embodiment 1 is that: after the train has driven a certain distance, the station announcement control module is triggered according to (4) formula (L 4 ≥180m) to judge whether to broadcast the prompt information about entering the station, at this time L 4 4 and L 5 , and then repeat the judgment according to formula (4), otherwise the operation ends.

Abstract

The invention relates to a train network control method of automatic stop announcement of a PIS (Passenger Information System). The method comprises the following steps that a distance computation module of a train network system calls a current train door state and a speed of a train, and judges the current train door state and a train operating state; if Y is equal to 1 and V is greater than 0m/h, the distance computation module calls L1, L2 and L3, and computes and outputs L4 and L5 to a stop announcement trigger control module; the stop announcement trigger control module judges whether an approaching prompt message is announced; if L4 is greater than or equal to 180m, the stop announcement trigger control module sends an approaching prompt message announcement instruction to the PIS, and judges whether an arrival prompt message is announced; and if L5 is less than or equal to 250m, the stop announcement trigger control module sends an arrival prompt message announcement instruction to the PIS. The control method of the automatic stop announcement of the PIS is simple and reliable, saves the cost, and facilitates post maintenance and debugging.

Description

technical field [0001] The invention relates to a method for controlling the automatic station announcement of a PIS system of an urban rail vehicle through a train network system, in particular to a train network control method for the PIS automatic station announcement. Background technique [0002] After searching, it is found that the Chinese patent with the publication number CN102568244A has announced a subway station reporting system and method. Infrared transmitters are set at each station to send infrared signals to the infrared receivers on the subway, and the processor on the subway monitors the infrared signals and sends Command the light at the site to turn it on or off. In this way, the communication between the platform and the subway is easily disturbed or even interrupted by external factors, so that the station reporting system cannot operate. [0003] As far as the applicant knows, the PIS (Passenger Information System) automatic station announcement cont...
