[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] like Figures 1 to 4As shown, an external extended antenna includes a transmitter body 1, a circuit board 4 is built in the front of the transmitter body 1, and the circuit board 4 is equipped with a communication female connector 5, and the communication female connector 5 is extended to the outside through a through hole on the side of the transmitter body 1, and the mating position of the communication female connector 5 and the through hole of the transmitter body 1 is filled with sealant. The present application reserves a communication female connector 5 mounted on the circuit board 4 on the side of the transmitter body 1, and the communication female connector 5 is not limited to any interface type such as N head, SMA or IPEX, but is compatible with the connection male connector 9 of the LORA antenna 6. A display screen 2 is provided on the top of the front of the transmitter body 1, and operation keys 3 are arranged on the bottom of the front of the transmitter body 1. A LORA antenna 6 is provided on the outside of the transmitter body 1, and a base 7 is fixed by a thread at the bottom of the LORA antenna 6. The LORA antenna 6 is externally connected to a spring wire 8, and the spring wire 8 is made of elastic material and can be stretched and extended freely, and the end of the spring wire 8 is connected to a connection male connector 9. The transmitter body 1 is built into the working space 10, and a receiver body 11 is arranged outside the working space 10. The receiver body 11 has three external antennas including LORA, 4G and WIFI, and the receiver body 11 and the transmitter body 1 are wirelessly transmitted through the LORA antenna 6. When in use, according to the working environment, the transmitter body 1 can be directly connected to the receiver body 11 through an extension cable, or the LORA antenna 6 can be connected to the receiver body 11 wirelessly through the spring wire 8. The base 7 of the LORA antenna 6 can be magnetically attracted and sucked to ensure a stable connection. The design of the two installation methods ensures that stable data transmission can be maintained even in a confined space with a weak signal. By timely transmitting monitoring data to the external control platform, safety warnings are provided to operators to reduce operating risks.

[0021] It is worth adding that: when the present application is applied to a confined working space 10, it is divided into two parts. The first step: a person hangs the transmitter body 1 by a rope and puts it into a confined space to measure the gas concentration in the confined space. The LORA antenna 6 of the receiver body 11 can be extended and magnetically attracted to the inner wall of the working space 10 to facilitate communication between the transmitter body 1 and the receiver body 11. The transmitter body 1 transmits the gas data to the receiver body 11 through the LORA antenna 6, and then the receiver body 11 transmits the data back to the background through WIFI or 4G; the second step: a person enters the confined space, hangs the transmitter body 1 on himself, and the receiver body 11 is also taken into the working space 10. The transmitter body 1 is responsible for the gas concentration detection in the confined space, and the receiver body 11 is responsible for the video monitoring in the confined space. The transmitter body 1 transmits the gas data to the receiver body 11 through the LORA antenna 6, and then the receiver body 11 transmits the gas concentration and the video taken by itself back to the background through WIFI or 4G;

[0022] The transmitter body 1 of the present application is a portable gas detector of model P20, and the receiver body 11 is a mobile explosion-proof video monitor of model S20.

[0023] Working principle: When using this external extension antenna, the present application reserves a communication female connector 5 mounted on the circuit board 4 on the side of the transmitter body 1. The communication female connector 5 is not limited to any interface type such as N head, SMA or IPEX, but is compatible with the connection male connector 9 of the LORA antenna 6. When in use, according to the working environment, the transmitter body 1 can be directly connected to the receiver body 11 through an extension cable, or the LORA antenna 6 can be connected to the receiver body 11 wirelessly through the spring wire 8. The base 7 of the LORA antenna 6 can adopt two forms of magnetic suction and suction cup to ensure a stable connection. The design of the two installation methods ensures that stable data transmission can be maintained even in a confined space with weak signals. By timely transmitting monitoring data to the external control platform, safety warnings are provided to operators to reduce operating risks.
