Abstract

The invention discloses a charge control cabinet based on field bus, which comprises a cabinet body, a cabinet door and a base. The cabinet body comprises the following parts: a traffic lane controller which is connected with a CAN bus intelligent control device and a character superimposer; the CAN bus intelligent control device which is communicated with a traffic lane equipment and is electrically connected with a multiple control connector and a switch power source; a terminator platoon which is connected with the multiple control connector and a lightning arrester; and a bus intelligent control device which comprises a microprocessor having a watchdog, a CAN bus controller, a CAN bus dispatcher, a RS232 signal dispatcher, a first optical coupled isolator, a second optical coupled isolator, an inverter and a Darlington transistor. The invention has the advantages of dustproof, shockproof, anti-jamming, reasonable design structure, convenient installation and maintenance and safe and reliable operation, thus meeting the demands for system upgrading.

Description

technical field [0001] The invention relates to the field of on-site control, in particular to a toll control cabinet based on field bus for automatic toll collection of various closed or open roads and bridges. Background technique [0002] With the rapid development of my country's economy and transportation network, more and more toll-based transportation equipment such as roads and bridges have been built, and the corresponding requirements for its traffic control management and toll collection methods are also constantly increasing. The toll collection system began to develop from manual to automatic, which effectively reduced the vehicle congestion rate at toll stations such as highways and bridges. At present, the automatic toll lane control mainly uses an industrial-grade multimedia computer as the core, and completes the control and status collection of the lane equipment by installing a multi-serial port expansion card and serial communication with the lane equipme...
