Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 Shown, a kind of embedded vehicle signal equipment state monitoring method, this method comprises the following steps:

[0028] 1. After the embedded on-board signal equipment status monitoring device is started, it periodically collects the status data of the on-board ATO / ATP system through the RS232 serial port;

[0029] 2. After the monitoring device sends a data acquisition command to the vehicle-mounted ATO / ATP system, it waits to receive the train status data fed back by the vehicle-mounted ATO / ATP system, and sets the waiting time and the number of failures to receive data;

[0030] 3. Judging whether the waiting time for receiving data exceeds the set waiting time, if yes, the data receiving fails, go to step 4, if not, go to step 5;

[0031] 4. Judging whether the number of failures to receive data exceeds t...

Abstract

The invention relates to a method for monitoring the state of an embedded vehicle-mounted signal device, comprising the following steps: 1) after the device for monitoring the state of the embedded vehicle-mounted signal device is started, collecting the state data of a vehicle-mounted ATO / ATP system periodically through an RS232 serial port; 2) sending data acquisition commands to the vehicle-mounted ATO / ATP system by the monitoring device, waiting for receiving the train state data fed back by the vehicle-mounted ATO / ATP system and setting waiting time and the failure times for receiving data; and 3) judging whether the time for waiting for receiving data exceeds the setting waiting time, if so, then the data receiving is in failure and step 4) is executed, and if not, step 5) and the like are executed. Compared with the prior art, the invention has the advantages of improving maintenance efficiency of the vehicle-mounted signal device, saving cost and the like.

Description

technical field [0001] The invention relates to a monitoring device for rail transit signal equipment, in particular to a method and device for monitoring the state of an embedded vehicle signal equipment. Background technique [0002] At present, the maintenance of on-board signaling equipment in rail transit is generally carried out by signal maintenance personnel directly on the train (driver's cab), and reads the maintenance and alarm information of on-board signaling equipment through a portable computer, and can only rely on special software provided by foreign manufacturers for problem analysis with processing. [0003] To this end, it is necessary to realize the localization of the maintenance system of the on-board signal ATO (Automatic Train Operation, automatic train operation system) / ATP (Automatic Train Protection System, automatic train protection system). [0004] Through the self-developed embedded vehicle-mounted signal equipment status monitoring device, t...
