Automatic fare collection system main control unit

Abstract

The invention relates to an automatic fare collection system main control unit which comprises a component object model (COM) express module, an input and output control module, an audio encoding and decoding module, a peripheral component interconnect (PCI)-industry standard architecture (ISA) change-over bridge and a reader-writer circuit. The audio encoding and decoding module and the PCI-ISA change-over bridge are connected with the COM express module. The reader-writer circuit is connected with the PCI-ISA change-over bridge. The audio encoding and decoding module comprises one way of audio input and one way of audio output. A PCI bus can be converted into an ISA bus through the PCI-ISA change-over bridge. The reader-writer circuit is used for reading information of tickets. The automatic fare collection system main control unit is high in expandability and flexibility. Port resource and size of a support plate can be collocated and adjusted flexibly according to requirements. The requirements of different projects can be met through different flexible collocation and combination of the COM module and the support plate, workload for designing the support plate is relatively small, development period is shortened, and meanwhile development cost is reduced. Ticket checking speed is improved through communication of a parallel bus and the COM module.

Description

technical field [0001] The invention relates to fare collection equipment, in particular to a main control unit of an automatic fare collection system for rail transit. Background technique [0002] At present, in the field of rail transit, the motherboards used in various automatic fare collection equipment are basically standard industrial control motherboards. Different Auto Fare Collection (AFC) projects and AFC equipment have different interface, function and performance requirements, often due to changes in structure, interface requirements, functional requirements, performance requirements, cost control and other factors. Re-select or customize the industrial control motherboard. The existing motherboards of industrial computer manufacturers are often difficult to fully meet the needs of various AFC equipment in terms of interface, structure, cost, and performance. It is necessary to re-customize industrial control motherboards that meet the needs. The development an...

Problems solved by technology

The existing motherboards of industrial computer manufacturers are often difficult to fully meet the needs of various AFC equipment in terms of interface, structure, cost, and performance. It is necessary to re-customize industrial control motherboards that meet the needs. The development and design cycle is long, which will also seriously affect AFC. The development cycle of the equipment will also lead to an increase in the development cost of AFC equipment
