Description

Technical Field

[0001] This utility model belongs to the field of communication technology, and in particular to an emergency communication command system for long tunnel construction that integrates intercom and sensing functions. Background Technology

[0002] In recent years, the rapid development of my country's high-speed railways has been remarkable, with large-scale construction of high-speed railways and passenger dedicated lines proceeding at a rapid pace. This development trend has not only driven the continuous improvement of railway construction technology standards but also placed higher demands on the safety and quality of projects. Against this backdrop, the importance of on-site communication equipment has become increasingly prominent, especially in the long tunnel sections of railway construction.

[0003] The construction environment of long tunnels is unique. Due to the complexity of the tunnel's internal structure and limitations in signal propagation, the communication distance and methods of conventional walkie-talkies are greatly restricted within the tunnel. This limitation not only affects real-time communication between construction personnel but can also seriously impact personnel safety and rescue efficiency in emergency situations.

[0004] For example, during a tunnel construction project, an accident occurred deep within the tunnel, requiring workers to evacuate quickly and request external support. However, due to the limited communication range of conventional walkie-talkies, on-site commanders struggled to obtain accurate information and make effective decisions in a timely manner, leading to delays in rescue efforts and increasing the risks for construction workers.

[0005] Therefore, developing an easy-to-operate, portable emergency communication and command system for long tunnel construction that integrates walkie-talkie and sensor functions is particularly important. Such a system can not only overcome the communication limitations of traditional walkie-talkies, ensuring a stable communication connection even deep within tunnels, but also monitor environmental parameters inside the tunnel in real time through sensor functions, such as temperature, humidity, and gas concentration, providing more comprehensive safety assurance for construction personnel.

[0006] Specifically, this emergency communication command system employs advanced wireless communication technology, combined with signal reflection and enhancement devices within the tunnel, to ensure stable transmission of communication signals. Simultaneously, the system can integrate multiple sensors to monitor various environmental indicators within the tunnel in real time and transmit the data to the command center via a wireless network, enabling commanders to promptly understand the situation on-site and make informed decisions.

[0007] In addition, the system should be easy to operate and carry, ensuring that construction personnel can use it quickly in emergencies, thereby improving rescue efficiency and safety.

[0008] In conclusion, with the continuous advancement of high-speed railway construction in my country, the demand for emergency communication and command systems at long tunnel construction sites is becoming increasingly urgent. Developing an efficient and convenient emergency communication and command system that integrates intercom and sensor functions will not only improve the safety and efficiency of railway construction but also demonstrate responsibility for the safety of every construction worker.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The technical problem solved by this utility model is achieved through the following technical solution:

[0027] An emergency communication and command system for long tunnel construction that integrates intercom and sensing functions, such as Figure 1 As shown, it includes a communication host and multiple communication extensions. The communication host communicates with the project department via the public network, and the communication host and extensions communicate with each other via low-frequency wireless self-organizing network signals. This is used to collect data from all extensions and transmit the data to the project department via the public network.

[0028] This utility model's emergency communication command system for long tunnel construction, integrating intercom and sensing functions, features a communication host and communication extension units that can receive voice content from the on-site intercom module and transmit the audio information from the work site back to the command center (project site) via a mesh network. The command center (project site) can then use the transmitted voice to gain real-time understanding of the on-site situation, facilitating rapid two-way voice communication with on-site personnel and enabling remote monitoring of work progress or resolution of on-site construction challenges.

[0029] The communication host and communication extensions have the same structure. The communication host includes a communication module, an intercom module, and a sensor module. The communication module is used for transparent transmission of wireless IP data and provides all important communication interfaces. The intercom module is used for intercom communication. The sensor module collects environmental data and converts it into network data. The communication module connects to the intercom module and the sensor module through a Layer 2 switch. The sensor module and the intercom module submit application data to the communication module through the switch, and the communication module forwards the data.

[0030] like Figure 2 and Figure 3 As shown, the communication module is connected to the main battery at the bottom via a snap-fit. The main battery supplies power to the communication module and the intercom module through an internal power distribution circuit. The main battery connects to the sensor module via a dedicated composite cable from an external aviation connector. The front of the communication module has a groove with screw holes on both sides. The pressure plate also has screw holes and is connected to the screw holes on both sides of the groove via threads. Magnets are located inside the side wall of the communication module for mounting the sensor module.

[0031] like Figure 4 As shown, the intercom module uses DJ1200, which includes an analog intercom and an analog-to-IP data conversion module. The analog intercom is mainly responsible for intercom and group functions, while the analog-to-IP data conversion module converts the analog data of the intercom into digital signals. The analog intercom and the analog-to-IP data conversion module are connected by a dedicated data cable.

[0032] like Figure 5As shown, the sensing module uses GS22 and includes a sensor and a network adapter module. The sensing module is responsible for collecting environmental data, and the network adapter is mainly responsible for converting the sensor's environmental data into network data. A magnetic attraction device is provided on one side of the sensor, which is used to attach to the side wall of the communication module, which has a magnet inside.

[0033] The sensing module is a professional unattended data acquisition terminal specifically developed for outdoor locations. This terminal, in conjunction with the emergency communication and command system for long tunnel construction sites, provides a professional data transmission solution. The sensing terminal is a multi-scenario environmental data acquisition terminal integrating various sensing modules, utilizing a mesh network to provide users with on-site environmental information feedback capabilities. In addition to integrating temperature, humidity, and methane sensors for both environmental and gas conditions, the device also reserves two RS485 sensor interfaces, providing strong support for the transmission of on-site environmental information back to the command center.

[0037] 2. Then insert the K-connector of the walkie-talkie cable into the headset jack on the right side of the walkie-talkie;

[0038] 3. Next, place the walkie-talkie back into the slot on the backpack radio, and tighten the screws clockwise again. Note that the walkie-talkie cover should be placed in the correct orientation. Figure 6 As shown, the pressure plate in the red box should face upwards;

[0039] 4. Finally, insert the other end of the walkie-talkie cable into the "walkie-talkie" connector and tighten the walkie-talkie antenna. The walkie-talkie connection is now complete.

[0040] Step 2: Connect the sensor module;

[0041] 1. First, locate the magnetic side of the sensor accessory;

[0042] 2. Locate the corresponding magnetic suction device on the side of the carrying stand, then slowly move the sensor magnetic surface towards the magnetic suction device to complete the adsorption.

[0043] Notice:

[0044] ① During the magnetic attraction process, there must be no other objects between the magnetic attraction device and the magnetic attraction surface, otherwise the sensor accessories will not be able to be attracted properly.

[0045] ② During the magnetic attraction process, never place your fingers or other parts of your body between the magnetic device and the magnetic surface to avoid injury.

[0046] ③ During the magnetic attraction process, the sensor's magnetic surface and the magnetic attraction device should not approach each other too quickly, so as to avoid the magnetic surface hitting the magnet and causing the magnet to break.

[0047] After the 3 sensors have finished adsorbing, place the methane sensor downwards and the temperature and humidity sensor upwards.

[0048] 4. After the sensor is adsorbed, connect the right-angle connector of the dedicated sensor cable to the "sensor" connector on the sensor accessory, with the cable tail facing upwards during connection.

[0049] 5. Finally, connect the other end of the dedicated sensor cable to the "sensor" connector on the backpack radio.

[0050] Step 3: Lift the toggle switch handle and pull it from the off side to the on side to power on the device.
