This article will introduce you to the functions and characteristics of the smart communication box and how to connect the hardware. It will also delve into the operation process of the Yuejia.com management system.
1. Functions of smart communication box
The smart communication box is a multi-functional device with the following key functions:
1）Integrate multiple protocols to achieve seamless connection with tankers of different protocol standards.
2）Realize intelligent management of gas stations, including station-level management mobile APP, and other functional modules.
3）4G (or 2G or WIFI) module to ensure smooth network connection.
4）Integrated GPS module for location tracking.
5）4 RS485 interfaces to realize wired communication with the tanker.
6）1 RS232 interface for interacting with the management system on the computer.
7）2 switching input ports and 2 switching output ports, used to monitor and control the status of the equipment.
8）Two 4-20mA analog input ports, which can be used to measure liquid level, etc.
9）1 USB interface for data transmission.
10）4 wireless module interfaces, supporting various communication methods.
11）Equipped with multiple communication protocols
2. Communication box port definition
Each port of the communication box is used for different functions, including a power socket, GPS antenna,
switching input and output, 4-20mA analog input, network module interface, SD card slot, display screen, LORA module socket, etc.
3. Hardware connection of smart communication box
The hardware connection of the smart communication box includes the following key steps:
1）Install the wireless module at the designated location.
2）Install the traffic card in the corresponding slot.
3）Install a GPS antenna.
4）Connect to the main power socket.
5）Install the display key film.
6）After ensuring that all connections are correct, the hardware connection of the smart communication box is completed.
4. The connection between the oil engine electronic control and the intelligent communication box
The connection between the oil machine’s electronic control and the intelligent communication box involves a wired connection and a wireless connection:
1）Wired connection communication line:
Make sure the communication cable is correctly connected to the communication interface of the smart communication box.
Connect the other end of the communication cable to the communication port of the motherboard. Make sure that line A and line B are connected correctly.
2）Wireless connection communication:
Insert the LORA module into the corresponding port on the mainboard of the smart communication box and connect the 4G antenna.
On the other side, connect the 485 communication interface of the electronic control and make sure the connection is correct.
3）Liquid level meter connection:
If you need to check the data and oil gun status, you can connect the liquid level meter and the intelligent communication box through the RS485 communication line,
but make sure that the liquid level meter occupies an independent port and cannot be shared with the electronic control.
4）The first power-on operation of the smart communication box
After the connection is completed, perform the first power-on operation:
Make sure that when the communication box is powered off, DIP switch 2 is changed to ON,
and then powered on again to use the communication module; DIP switch 4 is changed to ON,
and powered on again to use the WIFI module to communicate with the cloud.
Waiting for the communication box to initialize, the indicator lights will change sequentially,
and during normal operation, the mainboard’s display will display information.
5. Operation process of Yuejia.com management system
Yuejia.com management system is a powerful platform for real-time monitoring and management of data from multiple petrol stations. The following are the key functions and operating procedures of the system:
In the employee management interface, you can create employee login names and passwords for the gas station to ensure that only authorized personnel can view site data.
Website building process:
The website-building process includes creating a site, setting oil product types, configuring oil product unit prices, creating oil tanks, binding equipment, and creating employees. This series of steps ensures accurate information and data availability for the site.
Device binding is a key step. It establishes the connection between the smart communication box and Yuejia.com and configures the communication protocol parameters. This step ensures real-time transmission and monitoring of data.
Real-time equipment monitoring:
Through the real-time equipment monitoring interface, you can view the refueling data and unit price of each oil machine in real-time, and even perform remote start, stop, and preset refueling operations, which improves management efficiency.
