Description

Technical Field

[0001] The utility model relates to the application field of automatic fire alarm systems, in particular to a data reading device for automatic fire alarm systems. Background Art

[0002] The national standard GB 4717-2024 "Fire Alarm Controller" requires that the operating data storage unit is an essential component of the fire alarm controller (a detachable independent component), which is used to record fire alarm information, shielding information, fault information, supervision information, manual / automatic status information and other fire equipment operating status information in the automatic fire alarm system. This information can provide basic data support for fire supervision and inspection, and investigation of the causes of fire accidents. Fire management departments need to be able to read data from the operating data storage units of different manufacturers and manage and analyze the data.

[0003] Currently, relevant standards in Europe, the United States, Japan, and South Korea lack technical requirements for operational data storage units, and fire alarm controllers and other controller products lack similar functional components. The revised national standard GB 4717, "Fire Alarm Controllers," in my country has introduced technical requirements for operational data storage units, enriching the functionality of fire alarm controllers. On this basis, developing data reading devices for operational data storage units and researching data information application technologies can better leverage the role of fire alarm controllers in fire management, effectively meeting the practical needs of fire management departments and ultimately improving my country's fire safety and protection capabilities.

[0004] At the same time, because the information in the operational data storage unit is confidential between different companies but open to fire management agencies, an independent third-party organization is required to complete data export and analysis, and verify the operational data storage unit's compliance with protocol standards. As a professional research institution in the field of fire protection, our unit is carrying out this related work. Utility Model Content

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Background that needs explanation: The storage unit of the fire alarm controller is an essential component (a detachable independent component) required by the national standard for fire alarm controller products. It is used to record all event information of the automatic fire alarm system (which can be understood as similar to the black box of an airplane). The national standard requires that the operating data storage unit must support the Device mode of the USB2.0 protocol and provide a USB-B or USB-C interface. Therefore, the reading device uses a USB-A interface to connect to the storage unit (most cables currently on the market are USB-A to USB-B or USB-C cables, refer to the mobile phone charging cable).

[0021] The data reading device of the automatic fire alarm system of the present invention includes a base plate 1, a shell 2, a circuit board 3 and a light guide column 4. The circuit board 3 is fixed to the base plate 1 by a buckle 5, and the shell 2 is detachably connected to the base plate 1 by the buckle 5. A plurality of SMD LED lights are provided on the circuit board, and the light guide column 4 is sleeved on the outside of the LED lights and extends out of the shell 2; a plurality of interfaces for connecting external devices and an SD card slot are provided on the circuit board 3, and a plurality of buttons 6 are provided on the shell 2. The plurality of buttons 6 control the mode selection and data transmission of the reading device body and are electrically connected to the circuit board 3.

[0022] Furthermore, there are three interfaces on the circuit board 3, namely a USB-C interface 7 connected to the power supply, a USB-A interface 8 connected to the fire alarm controller, and an RJ45 interface 9 connected to the host computer.

[0023] The circuit board 3 is provided with a control processing unit (an MCU chip in this embodiment) and a data storage unit (an SD storage card in this embodiment). The control processing unit is connected to the host computer through the RJ45 interface 9 and is connected to the fire alarm controller through the USB-A interface 8.

[0024] Specifically, the USB-C interface 7 provided on the reading device circuit board is only used to power the reading device. The power supply voltage is 5V. Referring to the mobile phone charger mode, after power-on, the reading device is turned on and enters the standby state; the USB-A interface of the reading device is connected to the USB-B interface (or USB-C interface) of the storage unit of the fire alarm controller through an adapter cable, and the USB-A interface 8 can provide power support for the storage unit; the reading device has a total of six indicator lights, and the indicator light source is a surface-mount LED soldered on the circuit board. After emitting light, the light signal is transmitted to the upper shell of the reading device through the light guide column 4.

[0025] The control processing unit sends a data reading instruction to the fire alarm controller, and the data storage unit obtains the data of the fire alarm controller and sends all the data to the data storage unit for storage; the host computer sends a data reading instruction to the control processing unit, and the data storage unit obtains the data of the data storage unit and forwards it to the host computer for display.

[0026] In this embodiment, there are six LED lights and five buttons, and their functions are as follows:

[0027] The first LED light: storage mode indicator light, always on to indicate that the reading device has entered storage mode, and always off in other states

[0028] The second LED light: transmission mode indicator light, it is always on to indicate that the reading device has entered the transmission mode, and it is always off in other states.

[0029] The third LED light: reading status indicator, used to indicate the status of the information reading process. Flashing means that data is being transmitted, and constant light means that there is a fault in the communication process with the storage unit.

[0030] The fourth LED light: used to indicate the connection status with the storage unit. After the storage unit of the fire alarm controller is successfully connected, the indicator light will be on.

[0031] The fifth LED light: indicates the connection status between the storage unit of the fire alarm controller and the host computer. After the connection to the host computer is successful, the indicator light is always on, and it is always off in other states.

[0032] The sixth LED light: power indicator light, always on when powered on and always off when powered off.

[0033] First button: Storage mode button, press and hold for 3 seconds to enter storage mode.

[0034] Second button: Transfer mode button, press and hold for 3 seconds to enter transfer mode.

[0035] The third button: manual operation button for reading information, valid in storage mode. Short press once to send a read information instruction to the storage unit of the fire alarm controller. Long press for 3 seconds to instruct the reading device to cyclically send a read information instruction to the storage unit of the fire alarm controller until the storage unit of the fire alarm controller replies with all the information and stops automatically.

[0036] The fourth button: read fire alarm information button, valid in storage mode, short press once to send a fire alarm information read instruction to the storage unit of the fire alarm controller, long press for 3 seconds to instruct the reading device to cyclically send an information read instruction to the storage unit of the fire alarm controller until the storage unit of the fire alarm controller replies with all the fire alarm information and automatically stops.

[0037] The fifth button: Read fire alarm information button, valid in storage mode, short press once to send a read first fire alarm information instruction to the storage unit of the fire alarm controller, long press for 3 seconds to instruct the reading device to cyclically send a read information instruction to the storage unit of the fire alarm controller until the storage unit of the fire alarm controller replies with all the first fire alarm information and automatically stops.

[0038] Furthermore, the data of the fire alarm controller includes fire alarm information, shielding information, fault information, supervision information, manual / automatic status information and other fire-fighting equipment operation status information in the automatic fire alarm system.

[0039] When in use, select to start storage mode or transmission mode according to the usage scenario. After the reading device is powered on, the reading device automatically completes initialization and waits for instructions to select the working mode. The user presses and holds the storage mode button to enter the storage mode, and the storage mode indicator light lights up.

[0040] The storage mode means that the reading device is independently connected to the storage unit of the fire alarm controller. The user operates the buttons of the reading device to read the information stored in the storage unit one by one and store it in the SD card inserted on the circuit board.

[0041] This working mode is suitable for the working environment where fire supervision personnel supervise the automatic fire alarm system on site. That is, they carry a reading device to the site, copy the data of the storage unit on site to the reading device, and then return to the workstation to connect the reading device to the host computer. By operating the host computer, the data in the reading device is uploaded to the host computer and the data is displayed.

[0042] The transmission mode refers to the working mode in which the storage unit of the fire alarm controller is connected to the reading device, and the reading device is connected to the host computer. In this mode, the user cannot directly operate the reading device to read data. Instead, they need to operate the host computer to issue a reading instruction to the reading device. The reading device forwards the instruction to the storage unit. The storage unit responds to the instruction and sends the data to the reading device. At the same time, the reading device immediately forwards the data to the host computer for display.

[0043] The host computer is a computer used to run the software (). It provides at least one RJ45 port for connecting to the reader, enabling data exchange via the TCP / IP protocol. The reader is assigned a dedicated IP address upon shipment. Once the host computer software is running, enter the desired reader's IP address to establish a connection. Upon successful connection, the host computer software indicates a successful connection, and the "host computer" indicator on the reader illuminates.

[0044] When the reading device works in storage mode, the reading device has completed reading the data inside the target storage unit. The host computer selects "storage mode reading" and sends a data reading instruction to the reading device. The reading device uploads all the data in the SD card to the host computer. At the same time, the host computer translates the digital data into text information and displays it on the screen.

[0045] When the reading device works in transmission mode, the host computer selects "transmission mode reading" and can operate "read a message", "cyclically send and read a message", "read fire alarm information", "cyclically send and read fire alarm information", "read the first fire alarm information", and "cyclically send and read the first fire alarm information" commands respectively (the key operations of the reading device in storage mode are the same as those of the host computer, except that they become virtual keys for operating the host computer). After receiving the corresponding command, the reading device forwards the command to the storage unit. After the storage unit sends the stored data to the reading device, the reading device uploads the data to the host computer for display.
