Problems solved by technology

The communication between the ATP software and the ATO software is realized through the communication between the modules, which will cause the communication delay between the ATP software and the ATO software and cause the speed measurement and distance measurement error, which will be unfavorable to the response time and parking accuracy of the system. influences
At the same time, the module where the ATP software is located and the module where the ATO software is located cannot cross access to each other's external interface modules. Therefore, the number of external interface modules that need to be configured in the on-board train control system will increase exponentially. For example, figure 1 Among them, both the ATO interface module and the ATP interface module include a general input interface module, a general output interface module and an analog interface module, resulting in a waste of cost and space

Embodiment 1

[0027] Embodiment one safety computer module

[0028] Such as figure 2 As shown, a secure computer module according to an embodiment of the present invention includes a first channel and a second channel, and the first channel and the second channel form a two-out-of-two structure, wherein:

[0029] The first channel includes a first CPU, the second channel includes a second CPU, and both the first CPU and the second CPU run ATP software by creating ATP software threads and ATO software threads to run ATO software, and The priority of the ATP software thread is higher than the priority of the ATO software thread.

[0030] It should be noted that the safety computer module is the control core of the train control on-board equipment, which is responsible for obtaining information from each module of the on-board equipment, and controlling the safety of the train based on information such as track circuit information, train braking force, line gradient, train running speed, and...

Embodiment 2

[0046] Embodiment two safety computer

[0047] Such as Figure 5 As shown, according to a safety computer according to an embodiment of the present invention, the safety computer includes the safety computer module as described above, and also includes an external interface module connected to the safety computer module and external equipment, wherein:

[0048] The external interface module is used for the secure computer module to interact with the external device;

[0049] The external interface module includes a general input interface module, a general output interface module and an analog interface module shared by the ATP software thread and the ATO software thread, and a dedicated safe input interface module and a safe output interface for the ATP software thread modules and communication interface modules.

[0050] In an exemplary embodiment, the secure computer module is connected to the external interface module through a backplane connector serial bus.

[0051] S...

Abstract

The invention discloses a secure computer module and a secure computer. The secure computer module comprises a first channel and a second channel. The first channel and the second channel form a two-out-of-two structure. The first channel comprises a first central processing unit CPU. The second channel includes a second CPU, the first CPU and the second CPU operate ATP software by creating a train automatic protection ATP software thread and operate ATO software by creating a train automatic driving ATO software thread respectively, and the priority of the ATP software thread is higher than that of the ATO software thread. The ATP software thread is created through the first CPU of the first channel and the second CPU of the second channel respectively to operate the ATP software, and theATO software thread is used for operating the ATO software, so that the communication delay between the ATP software and the ATO software is reduced, and the parking precision of the train control system is improved.

Description

technical field [0001] The present application relates to but not limited to the technical field of train operation control, and in particular relates to a safety computer module and a safety computer. Background technique [0002] At present, all major signal manufacturers at home and abroad have their own on-board train control systems, and all manufacturers including Siemens, Casco and other companies have integrated Automatic Train Protection (ATP) software, Automatic Train Driving (Automatic Train Operation, ATO) software and other communication function software are distributed to different hardware modules, and between ATP software and external devices, and between ATO software and external devices, two-to-two communication is usually realized through external interface modules. [0003] Such as figure 1 As shown, since the ATP software and ATO software are distributed on different hardware modules, the module where the ATP software is located and the module where th...
