Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The remote restarting device of the present invention is described below with reference to fig. 1, and includes a power module, a relay module, a first CPU (Central Processing Unit ) module, and a second CPU module; the first CPU module is in signal connection with the relay module, the second CPU module is in signal connection with the relay module, the power supply module is electrically connected with the relay module, and the relay module is electrically connected with equipment to be restarted;
optionally, the remote restarting device is a circuit module based on the TMS570, and can be used for restarting the equipment on a daily basis and restarting when the equipment fails.
Optionally, two CPU modules communicate through an SPI bus with electromagnetic isolation to acquire data of the opposite end. The two CPU modules are communicated with the relay module directly or indirectly through Ethernet.
The power line of the power module is connected with the normally closed contact of the relay module, and the output end of the relay module is electrically connected with the equipment to be restarted. The relay modules are one or more, and each relay module is electrically connected with one device to be restarted, so that the one or more devices to be restarted are restarted at the same time.
The first CPU module is used for receiving a first restarting instruction issued by the monitoring server of the equipment to be restarted, processing the first restarting instruction to obtain a second restarting instruction, and receiving a second restarting instruction which is sent by the second CPU module and is obtained by processing the first restarting instruction by the second CPU module; when a second restarting instruction corresponding to the first CPU module is consistent with a second restarting instruction corresponding to the second CPU module, the second restarting instruction is sent to the relay module; the second CPU module and the first CPU module have the same function;
alternatively, in the case where the device to be restarted is a CI cabinet device, the monitoring server is an ATS (Automatic Train Supervision, train automatic monitoring system) server.
And under the condition that the equipment to be restarted fails, the monitoring server transmits a first restarting instruction to the two CPU modules. Optionally, the monitoring server communicates with both CPU modules via UDP (User Datagram Protocol ).
The two CPU modules receive the first restarting instruction, process the first restarting instruction, and send the second restarting instruction obtained after the processing to the other CPU module.
Optionally, processing the first restart instruction includes parsing the first restart instruction, obtaining a port number of the relay module to which the first restart instruction is to be issued, and repacking the first restart instruction.
Because the functions of the two CPU modules are the same, the second restarting instructions obtained after the two CPU modules are processed are the same under normal conditions. However, as one of the CPU modules may fail, or be hacked, or the received first restart instruction is null, the second restart instructions obtained after the two CPU modules process the first restart instruction are inconsistent. The second restart instruction in this case may cause erroneous operation of the device to be restarted, resulting in an operation problem of the entire line.
In order to ensure the safety and reliability of restarting, each CPU module adopts a two-in-two safety logic design, namely, a second restarting instruction is sent to the relay module only when the second restarting instructions obtained after the first restarting instructions are processed by the two CPU modules are consistent.

Optionally, the relay module does not act when receiving a second restart instruction sent by the CPU module; when receiving the second restarting instructions sent by the two CPU modules, the normally closed contacts of the relay modules are firstly opened and then are switched on under the control of the second restarting instructions, so that the power supply module is powered off to supply power to the equipment to be restarted, and the equipment to be restarted is restarted.
According to the embodiment, by using communication between two identical CPU modules and two-out-of-two logic of the CPU modules, under the condition that the restarting instructions processed by the two CPU modules are consistent, the restarting instructions are sent to the relay module for restarting control, so that the safety of processing logic inside the CPU and the reliability of output are ensured, the restarting of equipment to be restarted can be controlled remotely and automatically, the timeliness and the efficiency of equipment restarting are improved, and the reliability and the safety of the equipment to be restarted when the equipment to be restarted fails to restart are improved.

The two CPU modules also send the first restarting instruction received by the two CPU modules to the other CPU module. Under the condition that the first restarting instruction received by the other CPU module is judged to be empty, the first restarting instruction received by the other CPU module is sent to the other CPU module so that the other CPU module can execute the two-in-two logic after processing the first restarting instruction, and the safety of processing logic in the CPU and the reliability of output are ensured.
On the basis of the above embodiment, each CPU module in this embodiment is further configured to receive the clock signal of the second CPU module sent by the second CPU module, and send the second restart instruction to the relay module when the clock signal of the present CPU module is consistent with the clock signal of the second CPU module and the second restart instruction is consistent with the clock signal of the second CPU module.
Since the two CPU modules are identical, the clock signals are normally identical. The two CPU modules send the clock signals of the CPU module to the second CPU module, and mutually detect whether the clock signals of the CPU module and the second CPU module are consistent.
If the two CPU modules are consistent, the two CPU modules are known to normally operate; if the CPU is inconsistent, at least one CPU is known to run abnormally.

each CPU module sends a second restarting instruction to the relay module through the output control module, and the second restarting instruction is sent to the output control module under the condition that the second restarting instruction corresponding to the other CPU module is consistent with the second restarting instruction.
The output control module is used for sending the second restarting instruction to the relay module under the condition that the second restarting instructions sent by the first CPU module and the second CPU module are consistent.
Under normal conditions, the second restarting instructions sent by the two CPU modules and received by the output control module are consistent. In the case of a failure or interference of the CPU modules, the received second restart instructions sent by the two CPU modules may not be identical.
