Description

Technical Field

[0001] This invention relates to the field of substation fire safety management technology, and in particular to a dedicated interface device for substation fire control panel networking. Background Technology

[0002] Currently, substations typically contain multiple fire suppression control panels, the most common being the main transformer fire suppression integrated control panel and the dedicated gas fire suppression control panel for the capacitor room. The main transformer fire suppression integrated control panel generally has the function of monitoring fire situations and alarms in other fire protection zones within the substation's main building. Since most substations are unmanned, it is necessary to connect the substation fire alarm signals to a remote monitoring system, requiring remote monitoring personnel to be on duty 24 hours a day.

[0003] In actual operation, the signals connected to the remote monitoring system are only the combined signals of fire and fire alarms. This means that the remote monitoring system can only monitor fire alarm information, while fire protection information (such as when, where, and which equipment triggered the fire alarm) cannot be sent to the remote monitoring system. The main reason is that there are multiple manufacturers of fire protection control panels in the substation, and the fire transmission protocols of different manufacturers are incompatible.

[0004] Therefore, it is necessary to unify the transmission protocols for various types of fire information as much as possible, so that fire information and fire alarm information can be transmitted to the remote monitoring system in a timely manner. Summary of the Invention

[0005] The technical problem to be solved by the embodiments of the present invention is to provide a dedicated interface device for networking substation fire alarm control panels, which can unify the transmission protocols of various fire information and transmit fire information and fire alarm information to the remote monitoring system in a timely manner.

[0006] To address the aforementioned technical problems, embodiments of the present invention provide a dedicated interface device for substation fire alarm control panel networking, comprising a Modbus function board and a printer port expansion board; wherein...

[0007] One end of the Modbus function board is connected to the preset fire alarm signal output ports on multiple fire control panels, and the other end is connected to a preset shared monitoring and control screen in the remote monitoring system. This screen is used to collect fire alarm signals and fault signals detected by each fire control panel, and merge them into a fire alarm message signal for each fire control panel, which is then transmitted to the shared monitoring and control screen for display. The fire alarm signal is a voltage signal emitted by each fire control panel when it detects a fire within the protected area; the fault signal is a voltage signal emitted by each fire control panel when it detects a fault in the fire detection and transmission equipment within the protected area.

[0008] One end of the printing port expansion board is connected to the preset printing ports on the multiple fire alarm control panels, and the other end is connected to the preset video environment system in the remote monitoring system. It is used to parse the protocols of the multiple fire alarm control panels according to a preset protocol parsing mechanism, so as to obtain the fire information that each fire alarm control panel needs to report from the printed messages of each fire alarm control panel, and to carry the fire information of each fire alarm control panel into a fire message signal with the same format, and transmit it to the video environment system for storage and display. The fire information includes alarm type, alarm device name, time, and location; the alarm type includes fire alarm and fault.

[0009] The Modbus function board is connected to the fire alarm signal output port on each fire alarm control panel via a coaxial cable with a BNC connector.

[0010] The Modbus function board is pre-configured with at least 20 input signal ports and at least 3 output signal ports; wherein the input voltage is located at... + The output voltage is between DC 30V and DC 24V to DC 110V.

[0011] The printing ports on the multiple fire alarm control panels include RS232, RS485, DB9 and RJ45 network ports; the printing port expansion board integrates at least RS232, RS485, DB9 and RJ45 network ports.

[0012] The voltage of both the fire alarm signal and the fault signal is DC24V.

[0013] Implementing the embodiments of the present invention has the following beneficial effects:

[0014] This invention merges the fire alarm signals and fault signals of each fire control panel into a fire alarm message signal and transmits it to a shared monitoring and control screen in the remote monitoring system. It also unifies the transmission protocols of various fire information according to the protocol parsing mechanism, obtains fire information from the printed messages of each fire control panel, and carries them to the video environment system in the remote monitoring system in the same format, thereby achieving the purpose of timely transmission of fire information and fire alarm information to the remote monitoring system. Attached Figure Description

[0015] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, obtaining other drawings based on these drawings without creative effort still falls within the scope of the present invention.

[0016] Figure 1 This is a connection diagram of a dedicated interface device for networking a substation fire alarm control panel, provided as an embodiment of the present invention. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown in this embodiment of the invention, a dedicated interface device for substation fire alarm control panel networking includes a Modbus function board 1 and a print port expansion board 2; wherein,

[0019] One end of the Modbus function board 1 is connected to multiple pre-set fire alarm signal output ports (not shown) on fire control panels via coaxial cables with BNC connectors. The other end is also connected to a pre-set shared monitoring and control panel T1 in the remote monitoring system via a coaxial cable with a BNC connector. This connection is used to collect fire alarm signals and fault signals detected by each fire control panel, and combine them into a fire alarm message signal for each fire control panel, which is then transmitted to the shared monitoring and control panel T1 for display. The fire alarm signal is a voltage signal emitted by each fire control panel when it detects a fire within the protected area; its voltage is typically DC 24V. The fault signal is a voltage signal emitted by each fire control panel when it detects a fault in the fire detection and transmission equipment within the protected area; its voltage is typically DC 24V. In one example, the Modbus function board 1 has at least 20 input signal ports and at least 3 output signal ports. The input voltage is located at... + Output voltage is between DC 30V and DC 24V to DC 110V.

[0020] One end of the print port expansion board 2 is connected to the preset print ports (not shown) on multiple fire alarm control panels, and the other end is connected to the preset video environment system T2 in the remote monitoring system. It is used to parse the protocols of the multiple fire alarm control panels according to a preset protocol parsing mechanism, to obtain the fire information required to be reported by each fire alarm control panel from the print messages of each panel, and to transmit the fire information of each panel to a fire message signal with the same format to the video environment system T2 for storage and display. The fire information includes alarm type, alarm device name, time, and location; the alarm type includes fire alarm and fault. In one example, since the print ports on the multiple fire alarm control panels include, but are not limited to, RS232, RS485, DB9, and RJ45 network ports, the print port expansion board 2 integrates at least RS232, RS485, DB9, and RJ45 network ports.

[0021] Understandably, the dedicated interface device for the substation fire alarm control panel also includes a DC power supply board, which connects the Modbus function board 1 and the printer port expansion board 2 and provides DC power to both of them.

[0022] It should be noted that the printer port expansion board 2 has a predefined protocol parsing mechanism (as shown in Table 1 below), which allows different manufacturers' protocols to be parsed. The printer port of the fire alarm control panel uses different protocols. For example, the Haiwan JB-QG-GSTN3200 uses a 485 transmission line, and the printing protocol number is 158, 97, etc.; another example is the Panhai Sanjiang JB-QBL-MN / 310, which uses a 232 transmission line and the protocol number is 183.

[0023] At this time, the print port expansion board 2 copies the print message of each fire alarm control panel and forwards it to the printer of the fire alarm control panel without affecting the original function. At the same time, it interprets the print message into text fire information and transmits it to the remote video environment system T2 for storage and display through the specified communication protocol (such as in accordance with "GB 26875.3-2011: Alarm Transmission Network Communication Protocol" or power system dedicated protocol). For example, the fire information of a fire alarm control panel is fire alarm, temperature sensor 10, 22-04-04 09:38_062, capacitor room No. 2, etc.
