Abstract

The invention discloses an intelligent remote transmission device and a remote transmission instrument. The intelligent remote transmission device comprises a metal shell with an accommodating cavity and an opening in communication with the accommodating cavity, a first PCB arranged in the accommodating cavity, and a second PCB provided with both an antenna for the transmission of communication signals and a transparent portion. Through the transparent portion, the interior of the accommodating cavity can be viewed. The second PCB board is electrically connected with the first PCB and is in communication connection with the first PCB. The second PCB is also provided with a metal layer for shielding electromagnetic signals. According to the technical scheme of the invention, the interference of the static electricity, the direct current, low-frequency signals and microwave high-frequency signals on a communication frequency-band circuit inside the intelligent remote transmission device can be effectively prevented.

Description

technical field

[0001] The invention relates to an anti-electromagnetic interference intelligent remote transmission device and a remote transmission instrument. Background technique

[0002] Existing gas meters, electric meters or water meters are usually non-intelligent devices, and non-intelligent devices usually include a casing, a casing of a gas meter counting device, and an upper cover shell plate of the gas meter counting device. For non-smart devices, the shell of the counting device and the upper cover of the counting device are generally made of plastic, and the antenna installed in the shell will not affect the sending and receiving of communication signals. For smart remote transmission equipment, in order to resist electromagnetic interference, the shell needs to be made of metal. The entire counting device shell and its cover plate constitute a metal cavity closed to electromagnetic signals. At this time, for the communication circuit placed in the metal cav...
