AFIC+Fiber Optic Transmission Solution for No Network Coverage

Background of the Solution:
In certain security monitoring scenarios such as tunnels, caves, and other similar environments, traditional network-based monitoring systems face challenges due to the unavailability of network signal coverage. To address this problem, we provide a comprehensive system solution that utilizes the C2000 data logger combined with fiber optic technology. This solution aims to reduce reliance on network signals and overcome issues related to long transmission distances, high cable costs, and signal loss.

1) C2000 Data Logger:
The C2000 data logger is a high-performance data acquisition device with powerful computing capabilities. It can receive and process data collected by sensors and provides reliable local storage functionality.

2) Fiber Optic Technology:
Fiber optic technology is a high-speed, low-latency data transmission technology that uses light signals to transmit data through optical fibers. In scenarios with no network coverage, we can utilize fiber optic technology to establish point-to-point data transmission channels, enabling reliable data transfer.

3) System Operation:
a. Data Acquisition: AFIC or AFIL sensor devices transmit environmental and monitoring data to the C2000 data logger.
b. Data Storage and Processing: The C2000 data logger stores the collected data in local memory and processes it to ensure data security and integrity.
c. Fiber Optic Transmission: Utilizing fiber optic technology, the data stored in the C2000 data logger is transmitted to a remote monitoring center, cloud platform, or other target devices.
d. Result Presentation: Processed data can be displayed and analyzed through a remote monitoring center, cloud platform, or other external devices, allowing users to access real-time monitoring information.

4) Device Requirements:
* Two 100Mbps Fiber Optic Transceivers (requires power supply)
* RJ45 Cable
* LAN Cable (two units)
* Insert Card Router (requires power supply)
* Fiber Optic Cable (1000m or more)

Workflow:

1. Setting up the SIM Card Router:
1)Insert the SIM card into the dedicated SIM card router and install the antenna to ensure stable signal reception.
2)Place the SIM card router in an open area or where network signal coverage is good to ensure signal quality and reliability.

2. Fiber Optic Transmission Preparation:
1)Use a LAN cable to connect the SIM card router to the 100Mbps fiber optic transceiver.
2)Insert the fiber optic cable into the fiber optic interface of the 100Mbps fiber optic transceiver to ensure a stable connection for optical signal transmission.

3. Fiber Optic Cable Setup:
1)Configure the appropriate length of fiber optic cable according to the project requirements to meet the distance requirements for data transmission.
2)Insert the end of the fiber optic cable into the other 100Mbps fiber optic transceiver,ensuring clear and stable optical signal transmission.

4. C2000 Device Connection:
1)Use a LAN cable to connect the other 100Mbps fiber optic transceiver to the RJ45 (Ethernet interface), ensuring stable and reliable data transmission.
2)Connect the EJ45 interface to the ETH/RS232 interface of the C2000 device to establish a data transmission channel.

5. C2000 Device Configuration:
1)Connect the C2000 device to the RJ45 interface, POWER interface, and Device interface to ensure proper input, power supply, and output connections.
2)Configure and set the parameters of the C2000 device based on specific project requirements to achieve accurate data acquisition, storage, and processing functions.
