Problems solved by technology

[0003] The software algorithm of the controller involves stability, robustness, reliability, security, redundancy, comfort, etc. It needs to complete many computing tasks, and in some cases the computing resources in the execution time period have been used To the limit, in order to write efficient programs, programmers need to spend a lot of energy and time to care about the running speed, and sometimes they can't even meet the requirements
At the same time, due to the high integration of computing tasks, the upgrade design and security design of the system are very complicated, and the implementation is very difficult

Embodiment Construction

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

[0027] As shown in Figure 2, in the present embodiment, the controller of the magnetic levitation train of the present invention, it comprises the first control unit 1, the second control unit 2 and the communication unit 3 that are respectively used to carry out different tasks in the magnetic levitation train control system , the first control unit 1 and the second control unit 2 are connected through the communication unit 3 . Wherein, the first control unit 1 and the second control unit 2 are programmable components capable of implementing controller software algorithms, and two identical DSPs can be used (for example, the DSP can use model TMS320F2812). The software computing tasks of the entire controller are assigned to two DSPs for processing respectively, and each DSP realizes data exchange and cooperative work through the co...

Abstract

The invention is related to a maglev train controller including at least two or more control units and communication units which respectively perform different functions in the maglev train controlling system, with any two control units connected with each other in turn. The maglev train controller has properties in a simple and compact structure, a low cost, an improved control stability, an higher operating efficiency and higher safety.

Description

technical field [0001] The invention mainly relates to the field of control equipment for maglev trains, in particular to a controller for maglev trains. Background technique [0002] The magnetic levitation train uses magnetic support to make the train body out of mechanical contact with the track. The principle block diagram of the maglev train control system is shown in Figure 1. As shown in Figure 1, the maglev train control system is mainly composed of sensors, controllers, amplifying actuators and maglev train body. The sensor measures the suspension gap, generates a digital or analog signal and sends it to the controller, and the controller calculates and generates a control signal and outputs it to the power amplifier, which drives the electromagnet to generate a suspension force to suspend the car body at a predetermined position. It can be seen that the maglev train must have a suspension, guidance and braking control system with excellent performance to ensure a ...
