Problems solved by technology

In addition, for wireless transceiver equipment powered by intrinsically safe output power (referred to as intrinsically safe power supply), in order to ensure that the equipment can work normally as far as possible, the wireless transceiver power is usually limited. In this case, the negative pole of the antenna is connected to the metal shell of the wireless transceiver device, and the area of ​​the negative pole of the antenna is increased, which can effectively increase the distance of wireless transmission. Requirements for insulation resistance and power frequency withstand voltage

Embodiment 1

[0022] Embodiment 1: as figure 1 As shown, a wireless transceiver device powered by an intrinsically safe power supply for mines includes a metal casing 1 and a main control module 2 protected inside the metal casing 1, and the main control module 2 includes a The power block 3 of the intrinsically safe power supply and the wireless transceiver module 5 for receiving or sending wireless signals; the outside of the metal casing 1 is also provided with an antenna 4, and the negative pole of the antenna 4 is electrically connected to the metal casing 1, The power block 3 is provided with an isolation converter 7 capable of forming a physical isolation from the power input end. Specifically, the isolation converter 7 includes an isolation transformer for realizing physical isolation.

[0023] With the above structure, the negative pole of the antenna is connected to the metal shell, so that the transmission distance of the wireless signal can be increased. Physical isolation, so...

Embodiment 2

[0025] Embodiment 2: The difference from Embodiment 1 is that in this embodiment, the isolated converter 7 is an isolated Buck-Boost flyback converter, such as image 3 shown.

Embodiment 3

[0026] Embodiment 3: The difference from Embodiment 1 is that in this embodiment, the isolated converter 7 is an isolated Flyback flyback converter, such as Figure 4 shown.

Abstract

The invention discloses a wireless transceiving device powered by an intrinsically safe power supply for mines, which includes a power block for connecting the intrinsically safe power supply and a wireless transceiver module for receiving or sending wireless signals; it is characterized in that it also includes a metal shell and An antenna arranged outside the metal casing, the negative electrode of the antenna is electrically connected to the metal casing; a high-voltage capacitor is connected in series between the metal casing and the wireless transceiver module and / or the power block is provided with a Power supplies form isolated converters that are physically isolated. The invention has the advantages of ingenious structure design, and can increase the wireless transmission distance while meeting the requirements of insulation resistance and power frequency withstand voltage.

Description

technical field [0001] The invention relates to the technical field of mine safety equipment, in particular to a wireless transceiver equipment powered by an intrinsically safe power supply for mines. Background technique [0002] In recent years, with the development and application of wireless transmission technology, more and more wireless devices have been used in mine operations. Wireless transceiver equipment belongs to mine electrical equipment, which needs to meet the insulation resistance and power frequency resistance specified in "MT 210-1990". pressure requirements. In addition, for wireless transceiver equipment powered by intrinsically safe output power (referred to as intrinsically safe power supply), in order to ensure that the equipment can work normally as far as possible, the wireless transceiver power is usually limited. In this case, connecting the negative pole of the antenna to the metal case of the wireless transceiver device, increasing the area of ...
