The invention discloses a remote monitoring method and device for an explosion-proof distribution box, and relates to the field of explosion-proof distribution boxes. The method comprises the following steps: acquiring monitoring data of a plurality of explosion-proof distribution boxes in a target area; acquiring a priority coefficient of each piece of monitoring data; and compressing the monitoring data based on the priority coefficient, and transmitting the compressed monitoring data to a central server, so that the central server performs remote monitoring on the monitoring data. By implementing the technical scheme provided by the invention, efficient remote monitoring of the explosion-proof distribution box can be realized.

The present invention discloses an enterprise operation supervision system for enterprise management, which specifically relates to the field of equipment supervision. It collects signal strength data of vehicle-mounted monitoring equipment, uses the signal average and standard deviation to dynamically evaluate the stability of the communication environment, and intelligently determines whether it is suitable for data transmission. In an unstable environment, ensure that data is securely stored locally; in a good environment, extract the data update change index and the fault impact trend index to calculate the pre-evaluation coefficient, and compare it with the early warning analysis threshold to generate a warning signal, so as to timely discover potential problems and improve equipment reliability. By calculating the distance from the maintenance point, the vehicle's motion status can be monitored, and the early warning strategy can be dynamically adjusted to improve the safety, efficiency and controllability of vehicle operations, and more intelligently supervise corporate property.

The invention relates to an offshore underground high-frequency wireless communication device which comprises a transmitting unit and a receiving unit. The transmitting unit comprises a transmitting master control module, a transmitting circuit and a transmitting coil; the receiving unit comprises a receiving coil, a receiving circuit and a receiving main control module; the emission master control module controls the emission circuit to start and stop according to needs and outputs a coded modulation signal; the transmitting circuit carries out push-pull driving and resonance processing on the coded modulation signal and then loads the coded modulation signal to a transmitting coil to generate an alternating magnetic field; the receiving coil induces a signal of the alternating magnetic field and outputs an induction signal; the receiving circuit amplifies, filters and shapes the induction signal and then outputs a sampling signal; and the receiving master control module demodulates and processes the sampling signal to obtain a wireless receiving signal. The problem that data transmission between two short sections can be achieved only through traditional integrated manufacturing or mutual communication is solved, the problem that the working endurance time of an underground circuit is short under the battery power supply condition can also be solved, and reliable transmission of underground data is guaranteed.

The present invention provides a method for establishing secure multi-connections between a terminal and multiple access points, and relates to the field of communication technology. The present invention establishes a communication method between a network access point AP, a multi-link terminal STA MLD and a terminal entity STA, so that the multi-link terminal is not limited to connecting to a multi-link access device, but can also connect to multiple single-link access devices, or a single-link access device can be connected to a multi-link access device, thereby expanding the application scenarios of the multi-link terminal and improving the efficiency of the multi-link terminal in using network resources. It solves the problem that the prior art must be connected to an access device that also supports multi-link, and that multiple links can only be established on the same access device for data transmission.
