[0020] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Energy storage power station monitoring system implementation example:

[0022] like Figure 1 and Figure 2 As shown, the energy storage power station includes a secondary compartment, a battery compartment and a PCS compartment. The energy storage power station monitoring system of the present invention includes a fire protection subsystem, a security subsystem, a dynamic environment subsystem and an auxiliary control monitoring system. The auxiliary control monitoring system is respectively communicated with the fire protection subsystem, the security subsystem and the dynamic environment subsystem; the auxiliary control system is used to receive information from the fire protection subsystem, the security subsystem and the dynamic environment subsystem and display it in a centralized manner, and is also used for linkage between different subsystems.

[0023] like Figure 3 As shown in the figure, the fire protection subsystem includes three fire protection sub-units and a fire alarm host which are respectively arranged in the secondary compartment, battery compartment and PCS compartment. The fire protection sub-units include a fire alarm system, a manual alarm button, an audible and visual alarm, a smoke detector and a temperature sensor. The manual alarm button, the audible and visual alarm, the smoke detector and the temperature sensor are respectively connected to the fire alarm system; the fire alarm systems of the three fire protection sub-units are all connected to the fire alarm host through the CAN bus, and the fire alarm devices are connected to the auxiliary control and monitoring system through the protocol conversion device.

[0024] like Figure 4As shown, the security subsystem includes a security host, an NVR device, and three security sub-units. The three security sub-units are connected to the security host and NVR device via a ring network. The three security sub-units are respectively located in the secondary compartment, battery compartment, and PCS compartment. The security sub-units include cameras and access control systems. The cameras and access control systems are connected to the security host and NVR device via a ring network switch. The security host is connected to the auxiliary control and monitoring system via a protocol converter, and the NVR device is directly connected to the auxiliary control and monitoring system. By setting up the NVR device, the video stream information collected by all cameras can be sent to the auxiliary control and monitoring system for display, eliminating the need to set up a video host to display the video, further improving the integration of the energy storage power station monitoring information. By connecting each security sub-unit to the security host and NVR device via a ring network, signal transmission is made more stable and reliable.

[0025] like Figure 5 As shown, the dynamic environmental subsystem consists of three dynamic environmental subunits, located in the secondary compartment, battery compartment, and PCS compartment, respectively. These subunits include temperature and humidity sensors, water immersion sensors, fans, and an environmental monitoring host. The fans, temperature and humidity sensors, and water immersion sensors are each connected to the environmental monitoring host, which is then connected to the auxiliary control and monitoring system via a ring network switch and protocol converter. By connecting all environmental monitoring hosts to the auxiliary control and monitoring system through the ring network, signal transmission is more stable and reliable.

[0026] The protocol conversion device is used to convert the communication protocol of the fire alarm device into 104 or CMS protocol, and is also used to convert the 485 protocol of the security host into 104 protocol, and is also used to convert the communication protocol of the environmental monitoring host from 485 protocol to 104 protocol.

[0027] The control strategy of the energy storage power station monitoring system of the present invention is as follows:

[0028] The auxiliary control monitoring system receives and displays the video information collected by the camera of each security sub-unit in real time through the NVR device via the ring network switch; receives and displays the access control information and electronic fence information of each security sub-unit in real time through the protocol conversion device and the security host; receives and displays the information of the manual alarm button, sound and light alarm, smoke detector and temperature sensor of each fire sub-unit in real time through the protocol conversion device and the fire host; receives the information of the temperature and humidity sensor and water immersion sensor of each dynamic ring sub-unit in real time through the protocol conversion device and the environmental collection host of each dynamic ring sub-unit; thereby realizing the integrated access, management and centralized monitoring of multi-dimensional data of each auxiliary subsystem. When the auxiliary control system receives the alarm signal from the water level sensor of the dynamic environment subsystem, it sends a control instruction to the fire protection subsystem to control the sound and light alarm of the fire protection subsystem to alarm, thereby realizing the linkage between the dynamic environment subsystem and the fire protection subsystem; when the auxiliary control system receives the access control alarm or the infrared dual-detection intrusion signal from the security system, it sends a control instruction to the fire protection system to trigger the sound and light alarm of the fire protection subsystem, thereby realizing the linkage between the security subsystem and the fire protection subsystem; after the auxiliary control system receives the smoke alarm signal from the fire protection subsystem, it sends a control instruction to the dynamic environment subsystem to control the dynamic environment subsystem to turn on the fan for exhaust, thereby realizing the linkage between the fire protection subsystem and the dynamic environment subsystem.

[0029] The energy storage power station monitoring system of the present invention can uniformly display the data monitored by each subsystem, thereby improving the integration of monitoring information within the energy storage power station. By sending control instructions to other subsystems based on the alarm signal of one subsystem, linkage between different subsystems is achieved, which greatly enhances the equipment perception, defect detection, status control, active warning and emergency response capabilities of operation and maintenance personnel for auxiliary equipment, thereby improving the intelligent operation and maintenance level of the energy storage station auxiliary system, and improving operation and maintenance efficiency and equipment operation reliability.
