[0029] Example 1

[0030] This utility model provides a distributed architecture multi-station equipment operation data detection system, which sets up corresponding data acquisition devices and data communication equipment for each professional system of the station to realize distributed acquisition of relevant data of professional equipment and facilities such as station power distribution, elevators, and fire protection.

[0031] The distributed architecture multi-station equipment operation data detection system is configured with an LCD display screen, station host and multiple data gateways in the station monitoring center. The station host connects to the equipment and facilities of various professional subsystems such as power distribution, lighting, elevator, fire protection, etc. through the data gateways, such as field controllers, sensors, actuators, communication boards, etc. to collect data, and the LCD display screen displays the data.

[0032] The system's network architecture mainly consists of two levels: a field control-level bus network and a management-level network. The control-level bus network primarily connects various field bus devices, forming a control-level network via RS-485 bus. The management-level network mainly connects various network devices and host devices to form a local area network (LAN). Specifically, the system establishes a LAN at the station end and configures relevant network devices and data gateway devices. The LAN backbone physical link uses a BAS fiber optic ring network. In this embodiment, an exit-level ring network and a catwalk-level ring network are respectively set up at the station's exit level and catwalk level, and multiple BAS ring network fiber optic switches are used to establish the LAN.

[0033] This utility model system uses an embedded data gateway to collect power distribution data, elevator data, water supply and drainage data, and fire protection data from field instruments and controllers. The data gateway is equipped with a clock chip, which analyzes the data collected by the instruments on-site, adds timestamps, and then transmits the data or saves it locally. When a network connection is established, the data gateway proactively initiates a time synchronization request to synchronize with the data center and clock server. The data gateway also includes a programmable control unit, capable of executing localized edge computing algorithms and implementing automatic strategies, including issuing commands for scheduled tasks and conditional tasks.

[0034] For power distribution system data acquisition, this embodiment plans to connect 72 distribution cabinets in 27 distribution rooms at the target station. Power monitoring sensors and temperature sensors are installed in each distribution cabinet. The power monitoring sensors in each distribution cabinet are connected via RS485 communication lines to collect real-time data on parameters such as current, voltage, power, and temperature, as well as the operating status of the distribution cabinets. The station's distribution rooms are mainly distributed on the exit level, platform level, and waiting level. Each distribution room is equipped with a communication system, including a serial server, access switch, and fiber optic transceiver. The system connects to the BAS network via Ethernet and transmits the collected data to the station's main unit, displaying power supply system information in real-time on a large screen. The communication equipment in each distribution room communicates with the nearest BAS ring network communication cabinet or lighting distribution cabinet in the lighting system via network cables and fiber optic cables.

The lighting circuit is connected to eight RS-485 communication buses, and a Modbus communication gateway is connected in series on the eight buses. A serial port server is set up to realize bidirectional transparent transmission of data between the RS-485 serial port and the TCP / IP protocol interface, enabling the reading and monitoring of the switch status, lighting mode operation status, and current value of each lighting circuit and the lighting distribution cabinet.

[0036] Elevator system testing: In this embodiment, 18 elevators and 95 escalators within the station are equipped with communication devices connected to a local area network.

The water pump monitoring cabinet contains a DDC controller and a DDC control box, used to collect dry contact information from the secondary circuit, including water pump operating status, manual / automatic status, water pump fault status, and float level switch status. A level sensor is added to collect real-time foundation pit level data. Multiple DDC controllers, level sensors, and DDC control boxes are configured for monitoring the water supply and drainage subsystem. This monitors the water accumulation in the sump, sewage pit, and elevator foundation pit; monitors the working status of the water pumps for maintenance, and provides fault and high-level alarms. The DDC controller supports one RS-485 serial communication port and the Modbus RTU communication protocol. The selected DDC controller supports 8 digital inputs, 8 relay outputs, 6 analog inputs (0-10V or 4-20mA), and 2 analog outputs (0-10V or 4-20mA). The number of DDC controller points configured in the DDC acquisition box meets the 15% redundancy requirement. In this embodiment, a total of 54 DDC controllers, 61 liquid level sensors, and 18 DDC control boxes were configured.
