[0003] Emergency command and communication equipment in related technologies typically focuses on video surveillance and voice communication at the scene, mostly using 4G communication. However, it fails to consider situations where mobile signal base stations are unavailable or network stability is compromised in harsh environments. This results in the inability to transmit high-bandwidth video or extremely poor transmission efficiency. Furthermore, it can only collect relevant information perceived by on-site personnel through video footage; however, information perceived by on-site personnel may be inaccurate, and some information is imperceptible to the human body. This leads to low accuracy and inefficiency in acquiring on-site information, severely reducing the efficiency of emergency command. Utility Model Content

[0004] The purpose of this invention is to improve the data acquisition and data transmission efficiency of emergency command and communication equipment, thereby improving the efficiency of emergency command.

[0016] The LoRa voice interaction module acquires the encrypted digital signal and sends the encrypted digital signal to the first emergency command and communication device through the voice transmission antenna, so that the first emergency command and communication device receives the encrypted digital signal, decrypts the encrypted digital signal into a sound signal, and plays the decrypted sound signal.

[0034] The present invention will be described in detail below through embodiments.

[0035] In some remote areas, such as underground mines, forests, high mountains, remote seas, uninhabited areas, and areas without network access, communication failures may occur. In such cases, emergency command and communication equipment is needed to improve the efficiency of emergency command.

[0036] Emergency command and communication equipment in related technologies typically falls into two categories.

[0037] For the first type of emergency command and communication equipment, which typically focuses on video surveillance and communication at the scene, most use 4G communication and do not consider situations where mobile signal base stations are unavailable or network stability is compromised in harsh environments. This results in the inability to transmit high-bandwidth video or extremely poor transmission efficiency. Furthermore, it can only collect relevant information perceived by on-site personnel through video footage; however, information perceived by on-site personnel may be inaccurate, and some information is imperceptible to the human body. This leads to low accuracy and inefficiency in acquiring on-site information, severely reducing the efficiency of emergency command.

[0038] For the second type of emergency command and communication equipment, the environmental information detection module is usually placed separately in the emergency command and communication equipment. When using the emergency command and communication equipment, the information detected by the environmental information detection module is manually entered into a mobile application and then sent to the server. This method has the problems of low accuracy and low efficiency, which seriously reduces the efficiency of emergency command.

[0039] To address the aforementioned technical problems, this utility model provides a highly intelligent and integrated emergency command and communication device. This device integrates various types of environmental information detection modules onto a main control board. For example, temperature and humidity detection modules and BeiDou positioning modules can be integrated onto the main control board. For modules that cannot be integrated onto the main control board in some application scenarios, such as gas detectors, the data detected by the gas detectors can be transmitted to the main control board via Bluetooth. In this way, all environmental data collected by the environmental information detection modules will be transmitted to the main control board. When a mobile network is available, the main control board transmits all environmental data to the emergency command server via the mobile network. When a mobile network is unavailable, the main control board transmits all environmental data to other emergency command and communication devices via a LoRa (Long Range Radio) self-organizing network. If other emergency command and communication devices currently have a mobile network, they will upload all environmental data to the emergency command server via the mobile network. If other emergency command and communication devices do not currently have a mobile network, then all environmental data will continue to be transmitted to the next emergency command and communication device via the LoRa self-organizing network, until it reaches an emergency command and communication device with a mobile network, and then all environmental data will be uploaded to the emergency command server through the emergency command and communication device with a mobile network.

[0040] As can be seen, the emergency command and communication equipment provided by this utility model, due to the high integration of the environmental information detection module, can firstly improve the efficiency of environmental data collection; secondly, when a mobile network is available, the main control board can transmit environmental data to the emergency command server via the mobile network; and when a mobile network is unavailable, the main control board can transmit environmental data to the emergency command and communication equipment with a mobile network via a LoRa self-organizing network, thereby improving data transmission efficiency and greatly enhancing the efficiency of emergency command.

[0041] The following is a detailed description of an emergency command and communication device provided by this utility model.

[0042] like Figure 1 As shown, this utility model provides an emergency command and communication device 1. The emergency command and communication device 1 includes a housing 10, which includes an upper cover 11 and a lower cover 12. The upper cover 11 is equipped with a main control board 111. A temperature and humidity detection module 112, a Beidou positioning module 113, a long-range LoRa data transmission module 114, and a Bluetooth communication module 115 are integrated on the main control board 111. The upper cover 11 is also equipped with a 4G antenna 116, which is electrically connected to the main control board 111. The lower cover 12 is equipped with a gas detector 121, which communicates with the main control board 111 through the Bluetooth communication module 115.

[0043] The temperature and humidity detection module 112 detects the temperature and humidity of the current environment, the Beidou positioning module 113 locates the position and altitude of the current environment, and the gas detector 121 detects the content of various gases in the current environment.

[0044] The main control board 111 acquires the temperature and humidity detected by the temperature and humidity detection module 112; the main control board 111 acquires the location and altitude located by the Beidou positioning module 113; the main control board 111 acquires the content of various gases detected by the gas detector 121.

[0045] When a mobile network is available, the main control board 111 sends temperature, humidity, location, altitude, and the content of various gases to the emergency command server via the 4G antenna 116.

[0046] In the absence of a mobile network, the main control board 111 sends temperature, humidity, location, altitude, and the content of various gases to the emergency command and communication equipment with a mobile network via the LoRa data transmission module 114, so that the emergency command and communication equipment with a mobile network can send temperature, humidity, location, altitude, and the content of various gases to the emergency command server via the mobile network.

[0047] Specifically, the emergency command and communication equipment includes a housing, which comprises an upper cover and a lower cover. The upper cover houses the main control board, which integrates a temperature and humidity detection module, a BeiDou positioning module, a long-range LoRa data transmission module, a 4G antenna, and a Bluetooth communication module. The lower cover houses a gas detector, which is not directly integrated into the main control board. To transmit environmental data detected by the gas detector to the main control board, the gas detector communicates with the main control board via a Bluetooth module.

[0048] The system includes a temperature and humidity detection module to monitor the temperature and humidity of the environment in which the emergency command and communication equipment is located; a BeiDou positioning module to pinpoint the location and altitude of the equipment, and to track its movement, ensuring the safety of on-site personnel; and a gas detector to detect the concentration of various gases in the environment, including combustible gases, oxygen, hydrogen sulfide, and carbon monoxide.

[0049] Furthermore, the temperature and humidity detection module, after detecting the current ambient temperature and humidity, can send these data to the main control board; the Beidou positioning module, after locating the current ambient position and altitude, can send these data to the main control board; and the gas detector, after detecting the concentration of various gases in the current ambient environment, can send this information to the main control board via Bluetooth. In this way, the main control board can obtain various environmental data about the emergency command and communication equipment's current environment, including the current ambient temperature and humidity, the current ambient position and altitude, and the concentration of various gases in the current ambient environment.

[0050] Then, the main control board can send various environmental data, such as the current temperature and humidity, the current location and altitude, and the concentration of various gases in the current environment, to the emergency command server. There are two ways the main control board can send this environmental data to the emergency command server:

[0051] The first method is as follows: If the environment in which the emergency command and communication equipment is currently located has a mobile network, then the main control board can directly send various environmental data such as temperature, humidity, location, altitude, and the content of various gases to the emergency command server through the 4G antenna. In this way, the emergency command server can efficiently receive various environmental data of the environment in which the emergency command and communication equipment is currently located. Therefore, when there is abnormal data in the various environmental data, the emergency command efficiency of the emergency command server can be improved.

[0052] The second method is as follows: If the emergency command and communication device is currently in an environment without a mobile network, it can automatically transmit various environmental data of its current environment to another emergency command and communication device via a LoRa data transmission module at pre-set intervals. When the other emergency command and communication device receives the various environmental data, it first checks whether its own mobile network is available. If its mobile network is available, it can transmit the received environmental data, along with the environmental data of its own environment, to the emergency command server via the mobile network. If the emergency command and communication device detects that the mobile network is unavailable, it will transmit the received environmental data, along with the environmental data of its own environment, to the next emergency command and communication device via the LoRa data transmission module, until an emergency command and communication device with a mobile network receives the environmental data and transmits it to the emergency command server via the mobile network.

[0053] As can be seen from the above description, the emergency command and communication device provided by this utility model can still send various environmental data of its current environment to the emergency command server through the LoRa self-organizing network when there is no mobile network. It not only has high efficiency in collecting current environmental data, but also high efficiency in transmitting current environmental data to the emergency command server.

[0054] As can be seen, the emergency command and communication equipment provided by this utility model, due to the high integration of the environmental information detection module, can firstly improve the efficiency of environmental data collection; secondly, when a mobile network is available, the main control board can transmit environmental data to the emergency command server via the mobile network; when no mobile network is available, the main control board can transmit environmental data to the emergency command and communication equipment with a mobile network via a LoRa self-organizing network, and then send the environmental data to the emergency command server through the emergency command and communication equipment with a mobile network, thereby improving data transmission efficiency and greatly improving the efficiency of emergency command.

[0055] exist Figure 1 Based on the illustrated embodiment, in one implementation, the gas detector 121 is also used to detect the altitude of the current environment;

[0056] When the signal strength of the Beidou positioning module is greater than the preset signal strength, the altitude detected by the Beidou positioning module 113 and the altitude detected by the sea wave altitude calibration gas detector 121 is obtained.

[0057] If the signal strength of the Beidou positioning module 113 is less than or equal to the preset signal strength, the altitude detected by the gas detector 121 is determined as the altitude of the current environment.

[0058] In this embodiment, the gas detector can not only detect the content of various gases in the current environment, but also the altitude of the current environment. Since the BeiDou positioning module can also detect the altitude of the current environment, whether the altitude is determined by the gas detector or by the BeiDou positioning module can be determined in the following way:

[0059] If the emergency command and communication equipment is located outdoors, the signal from the BeiDou positioning module will be relatively strong, meaning the signal strength will be greater than the preset signal strength. In this case, the altitude determined by the BeiDou positioning module will be more accurate. Therefore, the altitude detected by the air pressure sensor in the gas detector can be compared with the altitude detected by the BeiDou positioning module, and the altitude detected by the gas detector can be calibrated. In this case, the altitude of the emergency command and communication equipment will be based on the altitude determined by the BeiDou positioning module.

[0060] If the emergency command and communication equipment is located indoors, the signal of the BeiDou positioning module may be weak or nonexistent indoors. In this case, the altitude of the emergency command and communication equipment should be based on the altitude indicated by the gas detector. Since the altitude indicated by the gas detector has already been calibrated by the BeiDou positioning module outdoors, the accuracy of the altitude of the emergency command and communication equipment is improved, resulting in a higher accuracy rate of the altitude of the emergency command and communication equipment transmitted to the emergency command server.

[0061] Based on the above embodiments, in one implementation, the emergency command communication device also has LoRa voice intercom functionality. In this implementation, such as... Figure 2 As shown, the housing cover 11 also includes a microphone 117, a LoRa voice interaction module 118, a data encryption chip 119, and a voice transmission antenna 1110. The LoRa voice interaction module 118 and the data encryption chip 119 are integrated on the main control board 111. The microphone 117 is electrically connected to the LoRa voice interaction module 118, and the LoRa voice interaction module 118 is electrically connected to the data encryption chip 119. The voice transmission antenna 1110 is electrically connected to the LoRa voice interaction module 118.

[0062] The microphone 117 collects sound signals and sends them to the data encryption chip 119.

[0063] The data encryption chip 119 converts the sound signal into an encrypted digital signal and sends the encrypted digital signal to the LoRa voice interaction module 118.

[0064] The LoRa voice interaction module 118 acquires the encrypted digital signal and sends the encrypted digital signal to the first emergency command and communication device through the voice transmission antenna 1110, so that the first emergency command and communication device can receive the encrypted digital signal, decrypt the encrypted digital signal into a sound signal, and play the decrypted sound signal.

[0065] Among them, the first emergency command communication device is an emergency command communication device that is pre-configured by the LoRa voice interaction module 118 and is located on the same LoRa channel as the emergency command communication device.

[0066] exist Figure 2 Based on the illustrated embodiment, in one implementation, the LoRa voice interaction module 118 also pre-sets the priority of multiple emergency command communication devices located on the same LoRa channel.

[0067] The LoRa voice interaction module 118 transmits encrypted digital signals to the second emergency command and communication device via the voice transmission antenna 1110; wherein the priority of the second emergency command and communication device is higher than that of the first emergency command and communication device.

[0068] Specifically, the LoRa voice interaction steps are as follows: Upon first use, press the start button on the emergency command communication device or the LoRa voice switch on the screen to activate the voice function. Then, set the LoRa channel, the priority levels of multiple emergency command communication devices on the same LoRa channel, and the voice volume on the screen. Additionally, the bottom cover of the enclosure can have a start button for initiating a voice call, which can be called the PTT button. This PTT button is electrically connected to the LoRa voice interaction module. After clicking the PTT button, voice communication between multiple emergency command communication devices on the same LoRa channel can be achieved. If priority levels are set for multiple emergency command communication devices, the higher-priority device will have priority for voice communication. After setting, you can directly press the start button to power on and press the PTT button to initiate a voice call.

[0069] After the microphone of the emergency command and communication equipment collects the analog sound signal, it sends the sound signal to the data encryption chip. The data encryption chip converts the sound signal into an encrypted digital signal and sends the encrypted digital signal to the LoRa voice interaction module. After the LoRa voice interaction module receives the encrypted digital signal, it sends the encrypted digital signal to the first emergency command and communication equipment on the same LoRa channel as the emergency command and communication equipment through the voice transmission antenna. After receiving the encrypted digital signal, the first emergency command and communication equipment decrypts the encrypted digital signal into a sound signal, amplifies the sound signal, and plays the decrypted sound signal through the speaker.

[0070] Furthermore, if priorities are set for multiple emergency command and communication devices on the same LoRa channel, the primary emergency command and communication device will send the encrypted digital signal to the secondary emergency command and communication device with a higher priority. This allows the secondary emergency command and communication device to decrypt the encrypted digital signal into an audio signal, amplify the audio signal, and play the decrypted audio signal through a speaker.

[0071] As can be seen, this embodiment enables voice communication between multiple emergency command and communication devices on the same LoRa channel. Furthermore, the emergency command and communication device that can act as the execution subject can communicate with emergency command and communication devices with higher priority, thus meeting the voice communication needs in practical applications.

[0072] Based on the above embodiments, in one implementation, such as Figure 3 As shown, the top cover 11 of the enclosure also includes a display touch screen 1111, which is electrically connected to the main control board 111. The display touch screen 1111 is used to display temperature, humidity, location, altitude and the content of various gases.

[0073] In this embodiment, the top cover of the enclosure can also be equipped with a touch screen. After the main control board acquires various environmental data such as temperature, humidity, location, altitude, and the content of various gases, it can display these environmental data on the touch screen. This allows staff to promptly understand the environmental data of the emergency command and communication equipment and facilitates further analysis.

[0074] Based on the above embodiments, such as Figure 4 As shown, the lower cover 12 of the enclosure is equipped with a built-in power supply 122, which is electrically connected to the main control board 111. The built-in power supply is used to power the main control board.

[0075] In this embodiment, to ensure that the emergency command and communication equipment can work properly, the lower cover of the enclosure can be equipped with a built-in power supply. By electrically connecting the built-in power supply to the main control board, the normal operation of the main control board can be ensured.

[0076] Based on the above embodiments, in one embodiment, the lower cover 12 of the housing is further provided with a power supply port 123 for supplying power to the built-in power supply 122, so as to charge the built-in power supply 122 through the power supply port 123; the lower cover 12 of the housing is also provided with a power indicator light 124, which is electrically connected to the built-in power supply 122, and the brightness of the power indicator light 124 is proportional to the power of the built-in power supply 122.

[0077] In this embodiment, the lower cover of the enclosure can also be equipped with a power supply port for the built-in power supply. This power supply can be charged via an adapter from a mobile phone or other terminal and a Type-C data cable, ensuring that the built-in power supply can power the main control board. Furthermore, the lower cover of the enclosure also features a power indicator light, which is electrically connected to the built-in power supply. The brightness of the power indicator light is proportional to the amount of power remaining in the built-in power supply. This allows staff to visually detect when the power of the built-in power supply is low and to charge it promptly.

[0078] Based on the above embodiments, in one implementation, the main control board 111 detects the power level of the built-in power supply 122 and displays the power level of the built-in power supply 122 through the display touch screen 1111 integrated on the main control board 111.

[0079] In this embodiment, since the main control board is electrically connected to the built-in power supply, the main control board can detect the power level of the built-in power supply in real time and display the power level of the built-in power supply through the display touch screen integrated on the main control board. In this way, the staff can intuitively see the power level of the built-in power supply on the display touch screen and charge the built-in power supply in time when the power of the built-in power supply is insufficient.

[0080] Based on the above embodiments, in one implementation, such as Figure 5 As shown, the top cover 11 of the box is also provided with a box closure detection board 1112, which is electrically connected to the main control board 111.

[0081] When the main control board receives the closing signal from the closing detection board, it performs an inventory check of the container's compartments and controls the container to enter sleep mode.

[0082] Furthermore, when the main control board detects the box opening signal from the box closing detection board, the main control board controls the box to switch from sleep mode to working mode.

[0083] Specifically, the top cover of the enclosure is equipped with a closure detection board, which is electrically connected to the main control board. When the emergency command and communication equipment is in operation, if the main control board receives a closure signal from the closure detection board, it can quickly inventory the storage space of the emergency command and communication equipment. It can also send various environmental data of the emergency command and communication equipment to the emergency command server and indicate whether the equipment is fully occupied via inventory indicator lights before entering sleep mode. Furthermore, when the main control board detects an open signal from the closure detection board, it can quickly switch from sleep mode to operating mode.

[0084] As can be seen, the box-closing detection board detects whether the emergency command and communication equipment has a box-closing signal, that is, it detects whether the emergency command and communication equipment is in working or sleep mode. If a box-closing signal is detected, it means that the emergency command and communication equipment is about to enter sleep mode. At this time, in order to reduce the power consumption of the emergency command and communication equipment, the main control board enters sleep mode. If a box-opening signal is detected, it means that the emergency command and communication equipment is about to enter working mode. At this time, the main control board enters working mode. In this way, the normal operation of the emergency command and communication equipment can be ensured.

[0085] To ensure clarity, the following description will be based on a structural schematic diagram of an emergency command and communication device provided by this utility model.

[0086] like Figure 6 As shown, the enclosure 10 of the emergency command and communication equipment 1 includes an upper cover 11 and a lower cover 12. A main control board 111 is installed on the upper cover 11, which integrates a temperature and humidity detection module 112, a Beidou positioning module 113, a LoRa data transmission module 114, and a Bluetooth communication module 115. The upper cover 11 also includes a compartment indicator light 1113, a display touch screen 1111, a speaker 1114, a microphone 117, a compartment closure detection board 1112, a 4G antenna 116, a main power switch 1115, and a voice transmission antenna 1110. The lower cover 12 includes a built-in power supply 122, a power indicator light 124, and a power supply port 123 for charging the built-in power supply 122. The power supply port can be a Type-C interface, which can be charged via a Type-C cable outside the enclosure. An expansion board 120 is installed on the lower cover 12 of the enclosure. This expansion board 120 can accommodate 10 compartment detection plates, 1 level, 1 power bank, 1 law enforcement recorder, 1 multi-functional military knife, 1 gas detector 121, 1 fireproof umbrella, 1 printer, 1 flashlight, 1 mobile phone, 1 PTT button, and 1 start button.
