specific Embodiment 1

[0024] like figure 1 The train maintenance operation process monitoring system shown includes: a number of mobile positioning devices, a back-end data processing server, and a data transmission network. The data transmission network is preferably a wireless communication system composed of wireless routers, network switches, and wireless network relays deployed over the maintenance depot. The mobile positioning device collects the location information of personnel (maintenance personnel or other staff). The back-end data processing server generates the actual operation trajectory of the personnel including the walking path and working time according to the personnel location information, and sends an alarm when the actual operation process of the personnel deviates from the standard operating specification.

[0025] Mobile positioning devices use inertial navigation technology for positioning, and inertial navigation technology has been widely used in the field of navigation ...

specific Embodiment 2

[0027] As a further improvement of the first embodiment, the monitoring system also includes a calibration unit that outputs calibration information to the mobile positioning device. The calibration unit includes: an origin calibration device placed in the maintenance warehouse. When the mobile positioning device moves to the origin calibration area, the origin The zeroing information output by the calibration device resets the position information and angle information stored in the mobile positioning device to zero. The correction information is stored in the memory chip of the mobile positioning device, which is automatically cleared after power-off, and automatically initialized after power-on.

[0028] In order to improve the accuracy of data correction, angle correction devices are installed at both ends of the maintenance track. When the mobile positioning device moves to the angle correction area, the correction information output by the angle correction device corrects...

specific Embodiment 3

[0031] As an improved solution of Embodiment 1 or Embodiment 2, the monitoring system also includes a front-end data processing industrial computer that preprocesses the personnel position information collected by the mobile positioning device and sends it to the back-end data processor, and is used to display the actual location of the personnel. A real-time trajectory interface display device for the operation trajectory.

[0032] The front-end data processing industrial computer uses socket programming technology to organize and sort the data received wirelessly, and then sends the data out through the wireless network. The front-end data processing industrial computer summarizes the position information of the maintenance personnel collected by each mobile positioning device, performs protocol conversion and waits for the wireless signal to be sent out when it arrives.

[0033] The personnel position information or personnel position information correction value sent by th...

Abstract

The invention discloses a train overhaul process monitoring system and monitoring method, and belongs to the technical field of train overhaul monitoring. The monitoring system comprises a movable positioning device, a rear end data processor and a data transmission network. The monitoring method includes the steps that the movable positioning device collects personnel position information and transmits the information to a rear end data processing server when the data transmission network has signals, and the rear end data processing server generates an actual personnel work track according to the personnel position information and warns when actual work processes of personnel are different from a standard operation specification. The system and the method avoid interference of an overhaul warehouse inner steel structure to positioning precision, and no-dead-corner monitoring is achieved. Real-time data correction of the movable positioning device is achieved, positioning precision is improved, line deployment is simplified, and construction is simple and convenient to achieve.

Description

technical field [0001] The invention discloses a train maintenance operation process monitoring system and a monitoring method, belonging to the technical field of train maintenance monitoring. Background technique [0002] Train warehousing maintenance is an important means to ensure the safety of train operation. The components of the train have high structural complexity, many maintenance items, and heavy maintenance workload, so it is difficult to guarantee the quality of maintenance. In order to improve the maintenance efficiency and ensure the quality of maintenance, it is necessary to implement real-time monitoring of the maintenance operation process, especially the maintenance procedures and each Monitoring of maintenance time of key parts. At present, the main technical solutions for real-time monitoring are: [0003] (1) Video monitoring: simply rely on the cameras arranged in the maintenance garage for monitoring. This kind of solution needs to arrange a large...
