A fiber optic communication gate controller

Abstract

The invention relates to the field of barrier gate control and provides an optical fiber communication gate controller. Including: optical fiber connector, optical fiber wavelength division multiplexer, first optical fiber communication module, second optical fiber communication module, network switching module, motor control module, barrier gate operation monitoring module; optical fiber connector and optical fiber wavelength division multiplexer The multiplexing ports are connected with optical fibers, the first demultiplexing port of the optical fiber wavelength division multiplexer is connected with the first optical fiber communication module with optical fibers, and the second demultiplexing port of the optical fiber wavelength division multiplexer is connected with the second optical fiber communication module with optical fibers The second optical fiber communication module is connected with the motor control module by a serial communication cable, and the first optical fiber communication module is connected with the first network port of the network switching module by a Gigabit Ethernet cable. The serial link for transmitting management instructions in the present invention independently uses one optical fiber transmission band, and is not affected by the bandwidth occupation of other barrier controller functional services, thereby ensuring real-time transmission and reception of management instructions at long distances.

Description

technical field [0001] The invention belongs to the field of barrier gate control, and more particularly relates to an optical fiber communication gate controller. Background technique [0002] In large parking lots and highway non-stop charging entrances, it is often necessary to manage multiple entrance and exit barriers with one management center to reduce labor costs and improve barrier passage efficiency. Since the management center needs to grasp the operating status of the barrier gate controller in time and predict the hidden dangers and lifespan of the barrier rod transmission mechanical parts and the barrier motor, the operation monitoring data and alarm messages of the barrier gate controller need to be transmitted to the management center through the network. The center also needs to issue management instructions and test instructions to the gate controller.

Problems solved by technology

However, the system exists: the underground parking lot is often unable to stably connect to mobile networks such as 2G, 3G, and 4G due to the influence of signal shielding, which makes it difficult for the barrier gate control system to be deployed in these parking lots with weak mobile communication network signals.

[0004] The 485 serial communication cable is used to connect although the distance is long, but its bandwidth cannot meet the needs of transmission of barrier gate operation monitoring data and other audio and video integrated business data transmission. The full occupancy of barrier gate application systems such as video intercom causes delays in receiving operational data, alarm data and issuing control commands

[0005] The general connection based on ordinary network cables can provide a large transmission bandwidth, but in large parking lots, it is necessary to consider the long-distance signal attenuation of ordinary network cables and use active relay equipment, which brings a lot of trouble to the network wiring construction of the parking lot. to a bigger challenge
