Embodiment Construction

[0052] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0053] The electric vehicle battery replacement system is an event-driven system, which adopts event-driven process chain (Event-driven Process Chain, EPC) for process modeling. In addition, the battery replacement system is a typical event-driven system with discrete input and output, and using a state machine for behavior modeling is a very effective and intuitive method.

[0054]The process flow of the electric vehicle battery replacement monitoring method based on event-driven process chain modeling is as follows: figure 1 shown, including the following steps:

[0055] A. The electric vehicle drives into the battery replacement station;

[0056] B. The RFID scanner at the entrance of the battery replacement station scans and reads the RFID tags of electric vehicles;

[0057] C. Authenticate the electric vehicle in...

Abstract

The invention relates to a monitoring method and a monitoring system for replacement of batteries of an electric automobile based on a state machine and an event-driven process chain technology. When the electric automobile drives into a battery replacement station, an RFID (radio frequency identification) scanner at the entrance can read the information of an RFID tag of the electric automobile, and then authenticates the electric automobile according to the tag, including authenticating the identity of the electric automobile and the information of a required battery box of the electric automobile. The monitoring system is used for judging whether the battery box required for the electric automobile has been charged after successfully authentication, if so, starting to guide the vehicle to park to an appointed position, otherwise, prompting a driver of the electric automobile to wait. After the electric automobile is parked in place for readiness, the batteries are replaced, after all of the batteries are replaced, settlement and payment are carried out, and finally, the electric automobile can be guided to move out of the battery replacement station. According to the invention, the whole procedure of replacement of the batteries of the electric automobile can be implemented, the problem that the degree of automation of replacement of the batteries is relatively low can be solved, and the battery replacement efficiency and reliability can be greatly improved.

Description

technical field [0001] The invention relates to electric vehicle battery replacement technology, in particular to an electric vehicle battery replacement monitoring method and a monitoring system thereof. Background technique [0002] Electric vehicle battery replacement is a complex process, including a series of links such as vehicle guidance, vehicle positioning, obtaining battery box demand information, delivering battery boxes, loading and unloading battery boxes, payment settlement, guiding vehicles out of the station, and battery box management. , Battery box replacement equipment, battery boxes, charging racks, chargers and many other equipment, the interaction between each link and equipment is intricate, and the transmission, loading and unloading of batteries must be carried out in accordance with a certain logic. How to coordinate each link and control logic to achieve It is a difficult problem to automate the entire process of battery replacement and ensure the ...
