Description

Mutual rescue device

Technical Field

The utility model belongs to the technical field of the fire rescue equipment and specifically relates to each other rescue ware.

Background

When a fireman rescues and rescues in a high-risk place, the fireman and background commanders need to know the working condition, the physical condition, the crisis degree of the field condition and the like of the fireman in time in the face of a complex rescue field. In order to solve the problem, the help caller is an important device worn on the body of the firefighter, and when the firefighter cannot finish rescue work by himself or even the safety of the firefighter is threatened, the help caller can be communicated with a command background or other help callers to obtain help or indication, so that the help caller plays a great role in rescuing trapped objects, ensuring the safety of the firefighter and the like. The communication module of the prior first-class distress call device is provided with two antennae, wherein an omnidirectional antenna is used for sending and receiving a distress signal and omnidirectional distress call work of search and rescue information; the directional antenna is used for directionally searching for a distress target under the assistance of the omnidirectional antenna, but actually, two antennas are arranged in one distress call device to interfere with each other, and the condition is more obvious when the frequencies of the two antennas are close to each other, so that the signal and data transmission of the distress call device is influenced; in addition, the two antennas occupy more space, are more complex in structure and have higher manufacturing and using difficulties.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that exists among the above-mentioned background art, provide a mutual ware of rescuing, its structure retrencies portable more, only is equipped with the communication that the lora antenna of qxcomm was used for realizing mutual ware of rescuing and server or mutual ware of rescuing simultaneously and server and other mutual communication between the ware in order to realize directional search function, avoids appearing the problem that the lora antenna interfered with each other and influences communication quality more than two kinds.

In order to achieve the above purpose, the technical scheme of the utility model has:

a mutual aid comprises a shell, a mainboard, a lora communication module and a battery, wherein the mainboard and the battery are arranged in the shell; the lora processor is communicated with the server through the lora antenna to achieve directional searching, or the lora processor is communicated with the server and other mutual rescue devices through the lora antenna to achieve directional searching.

In the help caller in the prior art, an omnidirectional antenna and a directional antenna are required to be equipped at the same time for realizing directional search, so that mutual interference between the two antennas influences the communication quality in the using process; but also makes the circuit connected with the device more complex and occupies more space. In the scheme, only the lora antenna is adopted to communicate with the server to realize directional search, or communicate with the server and other mutual rescue devices to realize directional search. The omnidirectional antenna can meet the communication at all angles, and because the omnidirectional antenna is a mutual rescue device, each mutual rescue device can directly communicate with each other and can confirm the position and the condition of the rescue device to be rescued through communication, so that each mutual rescue device does not need to communicate with a remote server; when the communication with the server is needed, only any help caller is needed to be positioned at the position where the communication with the server can be realized. Other mutual help devices transmit data and messages to be finally transmitted by the help caller which can communicate with the server, and can also finally realize the communication with the server, and the server can also send the received information such as the position of the help caller needing rescue to each mutual help device, so that directional rescue is realized instead of blind rescue. Under the less prerequisite of whole communication function affected degree, the problem that the communication influences each other between multiple antenna has been avoided to this scheme, and the structure of lora communication module is retrencied more moreover, and the inside volume of ware is rescued each other also is practiced thrift.

The length of the columnar spring antenna is long, the protrusion is small, the columnar spring antenna is not easily knocked when in use, and the signal transmission and receiving capacity is strong. And the antenna cover is matched with the spring in shape and protects the antenna cover inside, so that the antenna cover is far away from external injury. The double-deck lid that inner cup and enclosing cover formed has further strengthened protective force and water-proof effects, avoids the antenna to receive the influence.

Further, the casing includes face-piece and drain pan, the face-piece covers each other with the drain pan and closes, and both middle parts form the installation cavity, mainboard, lora treater and battery are located in the installation cavity. The structure that two casings closed each other is convenient operation more when the assembly, and mainboard, lora treater and battery can receive protection well in the installation cavity.

Further, still be equipped with waterproof circle between face-piece and the drain pan, waterproof circle is the silica gel material. The waterproof ring made of the silica gel material enhances the waterproof effect of the mutual rescue device, and can be more suitable for the mutual rescue device when being applied to water area rescue.

Furthermore, be equipped with display screen subassembly and alarm lamp on the face-piece, the mainboard with display screen subassembly and alarm lamp adjacent setting. The display screen component can be used for displaying various data, such as the position and information of another mutual aid, the position of the mutual aid, the current environmental temperature and time and the like; the alarm lamp is used for flashing to remind a user of attention in special conditions. In the design of position, because display screen subassembly and alarm lamp need set up in the position that shows prominently, consequently need set up on the face-piece, the mainboard sets up the space behind the face-piece rather than adjacent with it better to minimize the volume.

Further, one side of the main board back to the display screen assembly is provided with the lora processor and the battery, and a GPS antenna and the lora antenna are arranged above the main board. The mainboard rear side is equivalent to the middle part in whole ware of saving each other, hugs closely the mainboard and sets up lora treater and battery, both can make the lora antenna in about the middle position on saving each other ware thickness, also can make inner structure compacter as far as possible.

Furthermore, a loudspeaker and a buzzer are also arranged, the loudspeaker is arranged below the battery, and the sound-transmitting hole in the face shell is opposite to the loudspeaker; the buzzer is arranged between the lora processor and the bottom shell. The loudspeaker is less, and the required space in the thickness direction can be saved to the position setting of utilizing the battery below, and the sound-permeable hole on the face-piece is convenient for the sound and image to see through before. The general buzzer is thin and reminds a user in a vibration and buzzing mode, so that the thickness of the mutual rescue device is not excessively increased between the lora processor and the bottom shell, and the mutual rescue device can be closer to the body of the user when being worn, and a better reminding effect is achieved.
