Steering discrimination backup system and method for traction motor

Abstract

The invention discloses a steering discrimination backup system and a steering discrimination backup method for a traction motor. The steering discrimination backup method comprises the steps of enabling all submessages not to wait for response during message transmission at first, transmitting the messages in batches, carrying out confirmation once after the number of submessages specified by anupper computer is integrally transmitted, and carrying out the subsequent transmission after the confirmation is successful. Batch message transmission can be achieved without confirming once after the transmission of one sub-message is finished; the occurrence of WLAN hysteresis is reduced, the message transmission rate is improved, and the bearing performance of the WLAN is improved; besides, the steering discrimination backup system further has a function of retransferring through a stopped position, under the condition that the transmission is stopped in an unexpected state when the uppercomputer transmits a backup message or the backup message is transmitted to the upper computer, the byte number transmitted by the upper computer is registered or a backup terminal transmits the backup message to the byte number of the upper computer, so that when the backup message is continuously transmitted to the upper computer after the accidental state is eliminated, the transmitted sub-messages and the sub-messages transmitted to the upper computer do not need to be repeatedly transmitted, and time and labor are saved.

Description

technical field [0001] The present invention relates to the technical field of traction motors, and also belongs to the technical field of big data backup, in particular to a steering discrimination backup system and method for traction motors. Background technique [0002] To improve the discrimination accuracy and degree of automation of the traction motor steering of the multiple train set, there is a steering discrimination system for the traction motor of the multiple train set, the system includes an inclination sensor for collecting the inclination angle of the coupling of the traction motor of the multiple train set, The microcontroller transmits the inclination angle forming inclination sampling information to the upper computer; the upper computer compares the inclination sampling information it receives with a set threshold to determine the steering of the EMU traction motor. [0003] However, in the prior art, the inclination sampling information received by the ...

Problems solved by technology

[0003] However, in the prior art, the inclination sampling information received by the host computer is not backed up, and as the importance of big data becomes higher and higher, it is very important to require the inclination sampling information to be backed up. Necessary, this often requires the host computer to set up a wifi module to connect with the backup terminal in the WLAN, and encapsulate the inclination sampling information into a message and send it to the backup terminal for backup. With the continuous progress of WLAN, it is also required The host computer also needs the backup terminal to transmit the backup message for display, and the number of messages transmitted between the host computer and the backup terminal is increasing, thus forming the process of transmitting the message between the host computer and the backup terminal. The communication specification commonly used in WLAN transmission is a standardized protocol. The current message transmission method divides the message operation into the number of sub-messages and the capacity of each sub-message. When the message is used for backup terminal backup, The host computer first informs the backup terminal to transmit information such as the message capacity of the message, and then each sub-message is transmitted one by one according to an instruction required by the host computer and a response mode of the backup terminal until the transmission is completed, and the backup terminal sends When the backup message is delivered to the host computer, the message such as the capacity of the message that is required to be delivered to the host computer is transmitted through the host computer, and then the backup terminal returns the message mode, and the sub-messages of the backup message are delivered successively. text until the backup terminal transmits the backup message to the upper computer; this type of mode is not complicated to achieve, but it is accompanied by defects, just like: because the upper computer waits for the message after the end of the transmission. The response comes, and then the next message is delivered, which forms a delay in delivery, making the message delivery rate not high
