Embodiment Construction

[0067] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0068] figure 1 It shows a schematic flow chart of a turnout control method provided in this embodiment, including:

[0069] S101. The vehicle-mounted device acquires the status of the switch, and determines the target resource authority to be applied for according to the status of the switch;

[0070] Among them, the on-board equipment judges whether it is necessary to turn the turnout by querying the state of the turnout; if it is necessary to turn the turnout, it considers that it needs to apply for the exclusive state permission of the turnout;

[0071] specifically:

[0072] If the state of the turnout needs to be changed to meet the train operation, the target resour...

Abstract

The embodiment of the invention discloses a control method and device and a controller of a turnout. The control method comprises the steps that a vehicle-mounted device acquires the turnout state, and to-be-requested target resource permission is determined according to the turnout state; the vehicle-mounted device sends a first resource request to the turnout, wherein the first resource request comprises the target resource permission; the resource state of the turnout is acquired, and the resource permission of the turnout is distributed according to the resource state and the target resource permission; and the turnout is controlled according to a distribution result of the resource permission. According to the control method, a traditional interlocking technology is not followed, so that ground equipment like an interlock and a signal machine do not need to be arranged, the control logic is simplified, and the equipment cost and maintenance cost are reduced; and the turnout is subjected to resource permission distribution and control through judging the resource state of the turnout according to the resource request of the vehicle-mounted device, and before a train reaches required turnout and zone resources, the resources are requested and distributed, so that safety protection of the train is achieved, and the utilization rate of the line resource is increased.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, in particular to a switch control method, device and controller. Background technique [0002] Traditional rail transit technology generally adopts an interlocking system to perform logical calculations on the operation commands of station operators and on-site information, so as to realize centralized control and supervision of turnouts, routes and signals. The routing is to ensure the combination of a group of line resources in train operation. These line resources have certain associations and constraints. The essence of routing control is the management and maintenance of the combination of line resources. At the same time, a signal machine is arranged on the trackside to ensure the safety of the approach, complete the interlocking task, and realize the line safety protection of the train. [0003] However, the existing technology needs to arrange interlocking sys...
