Fig. 1 shows a block diagram of an information transmission apparatus 100 according to an embodiment of the present application, including an information transmitting device 110, a transition detecting device 120, and an information receiving device 130.
Taking a fire-fighting broadcasting system in the fire-fighting field as an example, in the fire-fighting broadcasting system, audio is transmitted by adopting an analog signal, namely, an analog signal is transmitted by adopting an analog line connection from a sound source device to a loudspeaker. Analog signals have a fatal disadvantage in that the longer the transmission distance is, the greater the interference is and the weaker the signal is.
In the present disclosure, by providing a plurality of transition detection apparatuses, the transmission distance of a signal is extended:
an information transmitting device 110 for transmitting an analog signal to the transition detecting device 120:
a conversion detection device 120 for receiving the analog signal, processing the analog signal (analog signal-digital signal-analog signal), and transmitting the processed analog signal to an information receiving device 130;
an information receiving device 130 for receiving the data transmitted from the conversion detecting device 120.
The transmission distance is increased by converting the analog signal into a digital signal.
In some embodiments, if a fire occurs when the network cable is disconnected, the speaker (information receiving apparatus 130) is unable to play out sound.
Therefore, referring to fig. 2, in the digital-analog signal conversion apparatus of the present disclosure, a switch having a ring network function conforming to an enterprise protocol is added, which is equivalent to using a network cable as a standby, in which one network cable is disconnected, and the switch is automatically switched to the standby network cable through conforming to the enterprise protocol, and when the main line is restored, the switch is automatically switched back through conforming to the enterprise protocol.
In some embodiments, the transition detection device 120, including the switch and signal conversion module, processes the analog signal by:
converting the received analog signal into a digital signal through a signal conversion module;
transmitting the digital signal to a switch of another conversion detection device through the switch, namely transmitting the digital signal among a plurality of conversion detection devices;
in another conversion detection device, the switch transmits the digital signal to the signal conversion module, which converts the digital signal to an analog signal and transmits to the information collection device.
According to another embodiment of the present disclosure, there is disclosed an information transmission line fault detection method applied to the above apparatus, including:
s310, the conversion detection device obtains the line state information through the switch.
In some embodiments, the network data command show erps instance 1 is sent to the switch in the same device through the signal conversion module in the conversion detection apparatus 120, and the state information of the line is obtained through the reply data of the switch.
Specifically, the signal inter-conversion and line detection device periodically acquires the line state related information of the switch paired with the device, and then comprehensively analyzes and judges the information to finally judge the states (opening and closing) of the lines.
Referring to fig. 4, three devices are illustrated (the minimum unit of the network change is formed, the maximum single ring can reach 255, and the more and more stable the devices are), the information transceiver device No. 1, and to send information to the information transceiver device No. 2, 2 lines can be selected:
item 1: no. 1 → 11.1 port of 192.168.1.11 → 21.2 port of 192.168.1.21 → No. 2;
item 2: no. 1→192.168.1.11.2 port→ 192.168.1.31.31.1 port→ 192.168.1.31.2 port→ 192.168.1.21.21.1 port→no. 2;
at this time, the switch automatically takes a path as a main loop through conforming to the looped network protocol of the enterprise, and usual data is transmitted according to the path, such as the 1 st path. If one of the wires in the main loop is disconnected (e.g., wire 1), the switch will automatically switch to the backup loop, e.g., wire 2. Meanwhile, the signal inter-conversion and line detection equipment can acquire the current state of the line from the switch matched with the signal inter-conversion and line detection equipment at regular time, and can lock the specific position of the disconnected line at the first time.
The module can be matched with other fire-fighting systems through a network interface and a UART communication interface on the signal inter-conversion and line detection equipment, so that the linkage among the systems is realized, namely, the signal inter-conversion and line detection module is accessed, and the functions can be realized by combining different protocols.
Step 1, logging in a switch:
the 23 ports of the switch are telnet in a TCP manner via TCP/IP network protocol. And then, through network data interaction, a user name and a password are sent to the switch, and the login is successful.
Step 2, entering a switch privilege mode:
a network data command en is sent to the switch to enter the switch privileged mode.
Step 3, obtaining the states of the line 1 and the line 2 (case 1):
the network data command show erps instance 1 is sent to the switch, and the reply data of the switch is analyzed to judge whether the line fails or not;
case 2: because the ring network is composed of physical interfaces and G5 and G6 ports of the switch are used, the states of the two ports of the switch can be obtained only through commands. That is, network data commands show interface G5 and show interface G6 are sent to the switch, and the reply data of the switch is analyzed to determine whether the line fails.
S320, analyzing the line state information to determine the state of each line.
In some embodiments, case 1 is targeted.
