The invention discloses a network sharing method and electronic equipment, and the method comprises the steps: enabling a network bridge node to be in bridge connection with an external network port, and enabling the network bridge node to be in bridge connection with an internal network port; the forwarding configuration of the first system module is changed, so that a network signal can be sent to the second system module through the external network port, the network bridge node and the internal network port, and the second system module can be networked through the internal network port; and changing the configuration of the external network port and the configuration of the network bridge node, so that the first system module can be networked through the network bridge node. The network sharing method and the electronic equipment provided by the invention have the advantages of normal use of the local application and good equipment performance.

This invention discloses a coal and gas outburst monitoring and pressure relief device, relating to the field of coal mine gas outburst prevention technology. It includes: a monitoring chamber, installed through a borehole in the outburst hazard zone of the coal seam and fitted to the inner wall of the borehole casing; a feedback regulating chamber, fixedly fitted to the inner wall of the casing, located at the rear end of the monitoring chamber, and internally equipped with a movable transmission ring surface; multiple support columns arranged in a ring, connecting the monitoring chamber and the feedback regulating chamber; multiple transmission shafts arranged in a ring, located on the side opposite to the monitoring chamber, one end passing through the feedback regulating chamber and fixedly connected to the transmission ring surface; a closed regulating device, fixedly connected to the inner wall of the casing and slidably connected to the other end of the transmission shaft; and a pressure relief device, one end fixedly connected to the inner side of the closed regulating device, and the other end fixedly connected to the rear end of the closed regulating device via a connecting ring surface. This invention achieves a monitoring-pressure relief-reset closed loop, significantly improving the safety and reliability of coal and gas outburst disaster prevention and control.
