Embodiment Construction

[0027] The present invention is described in detail with reference to the drawings and embodiments.

[0028] This embodiment is the implementation of the method described in the present invention on the locomotive auxiliary power control device, but the same method can also be applied to the traction control device, the difference is only that the extracted parameter lists are different, and there will be no other impact on applicability. figure 1 The schematic diagram of the hardware designed for the present invention, it should be noted that only the relevant parts of the present invention are drawn in the figure, and other parts of the control device are omitted in the figure.

[0029] Such as figure 1 It can be seen that the processor used in the control device of this embodiment is a TI company DSP28335 processor, and the processor itself is integrated with a RAM memory and a FLASH memory, so the embodiment completes the implementation of the present invention based on th...

Abstract

The invention relates to a rail transit control device parameter configuration method, in particular to a rail transit control device parameter configuration method based on function safety. The universality problem of the control device applied to different types of products is solved, and the device has the cost advantage in the aspect of function safety certification. In addition, repeated debugging of the control device in the development and use process can be greatly facilitated through parameter configuration, and the usability, reliability and safety of the device are improved. A special space is opened up in a control device memory to serve as a parameter configuration storage space. The control device exchanges data with the upper computer through communication; and the upper computer designs a parameter list corresponding to the control parameters of the control device and a parameter read-write control function, reads the parameters of the parameter configuration storage space of the control device through communication with the control device, and issues and writes the parameters of the parameter list of the upper computer into the parameter configuration storage spaceof the control device.

Description

technical field [0001] The invention relates to a parameter configuration method of a rail traffic control device, in particular to a parameter configuration method of a rail traffic control device based on functional safety. Background technique [0002] With the rapid development of domestic rail transit and the in-depth development of the electronization of locomotives and EMU trains, more and more control devices are applied to the various systems of these locomotives. Based on this situation, it is very necessary to adapt the control device to different model applications as much as possible. At the same time, with the continuous deepening of safety awareness in the industry, it is inevitable to review the functional safety of control devices, and it is inevitable for products to have functional safety certification. Functional safety standards and audits require that general-purpose products must have parameter configurations, otherwise the product faces repeated cert...
