Problems solved by technology
However, the traction module and the stator switch station are arranged along the line and are far away from each other. Traditional mechanical locking or electrical interlocking cannot complete the locking between the switch cabinet and the power distribution equipment far away; the power supply network structure of the maglev transportation system It is complicated and not suitable for the use of program locks with simple wiring; traditional electromagnetic locks cannot reliably detect the three-phase power supply with real-time changes in frequency, phase, and amplitude in the maglev transportation traction power supply system, so it cannot reliably realize the anti-misoperation locking of switch cabinets

Embodiment Construction
[0045]The core of the present invention is to provide an anti-misoperation locking system, method and maglev traffic system. The present application is a logic anti-misoperation latching system for switch cabinets built on the basis of the complex power supply network structure of the maglev traffic traction power supply system. It can indirectly judge whether the target switchgear is energized, and control the locking device on the target switchgear to lock when the target switchgear is energized, so that the target switchgear with potential electrification will be kept in the locked state, with high safety and reliability.
[0046] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described emb...

The invention discloses an anti-misoperation locking system and method, and a maglev traffic system. The anti-misoperation locking system comprises a partition control system, a plurality of locking devices and field control systems. Each field control system obtains the on-off state of the connected switch cabinet and uploads the on-off state to the partition control system; obtains all switch states from the zone control system, and determines a virtual live-line state of the target switch cabinet according to a preset switch cabinet power supply association relation network model and all switch states; and controls the locking device to execute locking operation if the target switch cabinet is virtually electrified. It can be seen that the anti-misoperation locking system is built based on a complex power supply network structure of a maglev traffic traction power supply system, whether the target switch cabinet is electrified or not is indirectly judged by analyzing the switch cabinet power supply incidence relation, and the locking device on the target switch cabinet is controlled to lock when the target switch cabinet is electrified, that is the target switch cabinet with the electrified hidden danger is kept in a locked state, and the safety and reliability are high.
Description
technical field [0001] The invention relates to the field of maglev traffic power supply, in particular to an anti-mistake locking system, method and maglev traffic system. Background technique [0002] The maglev traffic traction power supply system includes multiple traction power supply partitions. The power supply principle of each traction power supply partition is as follows: the traction module outputs a three-phase power supply whose frequency, phase and amplitude change in real time according to the traction control requirements of the maglev vehicle. Each stator switch station and feeder cable are sent to each linear motor long stator, thereby generating the traction force required for the operation of the maglev vehicle. [0003] Specifically, the traction module includes several output switch cabinets; each traction power supply partition has a large number of stator switch stations along the line, and each switch station has several stator switch cabinets. Base...
