Technical Field

The utility model relates to a wireless transmitting equipment field, especially a radio signal reinforcing means.

Background

The main structure of the alarm equipment comprises one or more probes and a set of receiving mechanism, wherein the probes are divided into a wireless probe and a wired probe, when the one or more wireless probes work, the probes transmit alarm signals to a wireless receiving circuit module of the receiving mechanism in a wireless mode or a wired mode after detecting the alarm signals, and then the receiving mechanism realizes that the on-site alarm sound frightens thieves under the combined action of related circuits or sends the alarm information to a remote user through a telephone alarm module and a short message alarm module, so that a good anti-theft effect is achieved.

The wireless transmitting circuit module has the further disadvantage that the wireless signal transmitted by the wireless transmitting circuit module is influenced by surrounding buildings (particularly high-rise buildings), the transmitting distance of the wireless signal is shortened, and therefore, when the distance between the wireless probe and the receiving mechanism is far, the receiving mechanism cannot work normally and cannot effectively generate an alarm signal due to the fact that the wireless signal cannot be effectively transmitted. Based on the above, it is particularly necessary to provide a device capable of effectively ensuring wireless signal transmission after an alarm condition occurs in a monitored area.
