Problems solved by technology
Due to the inconsistent hardware interfaces of the internal modules and circuit boards of the automatic ticket gate, and there are many types, there are many types of cables inside the device, a large number of cables, and a long cable length; at the same time, there may be certain interference between cables in the device. It affects the transmission quality of the signal, and also affects the integration and expansion of the system
In addition, due to the number and variety of cables, it is very difficult to install, route and maintain equipment
Especially when the on-site automatic ticket gate equipment fails, because there are many cables inside the equipment and the installation and wiring are complicated, it is impossible to quickly determine the cause of the failure, making maintenance and repair difficult

Embodiment Construction
[0018] The automatic ticket gate machine based on the CAN bus architecture, which includes a host machine and a slave machine, and a host machine and a slave machine form an automatic ticket gate machine channel;
[0019] The main engine is integrated with a general logic control board, and there are two identical CAN nodes integrated on the general logic control board. The other modules of the main engine except the general logic control board are respectively equipped with CAN input nodes and CAN output nodes. One of the CAN nodes Connect to the CAN input node corresponding to the adjacent module through the transmission line, and the CAN output node of the corresponding module is connected to the CAN input node of the other adjacent modules through the connecting line, until the CAN input nodes of all modules are respectively connected to the corresponding The CAN output node of the adjacent module;
[0020] The slave connection board is integrated inside the slave machine,...

The invention provides an automatic ticket checker based on a CAN bus architecture, and aims to reduce the complexity of electric appliance design of the automatic ticket checker. The connection mode of the internal modules and the circuit board of the automatic ticket checker is converted into mutual connection between nodes of the bus master controller by taking the pass logic control board as the bus, so that the connection complexity between the modules and the number of connection cables are reduced. The system comprises: a host; and a slave. A passage logic control board is integrated in the host, two same CAN nodes are integrated on the passage logic control board, and other modules, except the passage logic control board, of the host are respectively provided with a CAN input node and a CAN output node; and a slave connecting plate is integrated in the slave, a CAN input node and a CAN output node are integrated on the slave connecting plate, the other modules, except the slave connecting plate, of each slave module are respectively provided with the CAN input node and the CAN output node, and the other CAN node is connected with the CAN input node of the slave connecting plate through a bridging line.
Description
technical field [0001] The invention relates to the technical field of automatic ticket checking machines, in particular to an automatic ticket checking machine based on CAN bus architecture. Background technique [0002] Along with the rapid development of urban rail transit, the automatic ticket gate as the control equipment for entering and exiting subway stations is also developing rapidly with the rapid development of urban rail transit. From the earliest use of the three-bar automatic ticket gate without access logic, it has developed into the more common and popular automatic ticket gate with scissor doors and flapping doors with more complex access logic, to the use of computer vision technology-based Automatic ticket gate, it can be seen that the development of automatic ticket gate equipment technology has become faster and faster with the rapid development and innovation of urban rail transit and science and technology, and the technical requirements of urban rail...
