The invention relates to a wireless wideband access network, equipment and an access method thereof; wherein, the access method comprises the concrete steps as follows: at least a gateway node and at least a network node form a corresponding wideband access network; the gateway node and the network node respectively comprise a self-help gateway node and a self-help network node which are achieved by the terminal equipment with prearranged processing function in the network; furthermore, the gateway node is connected with a wire network, carries out the information interaction by wires, and provides the wireless access service by the gateway node and the network node; in the invention, the terminal equipment with the prearranged processing function in the network is used as the self-help gateway node and the self-help network node, and a network which can provide the wideband access service is formed in a self-help way; therefore, by the realization of the invention, the existing wire access resource can be effectively utilized, and the wideband wireless access service in a bigger area (including global network range) can be achieved at lower cost.

The invention relates to the field of temperature monitoring based on wireless sensor network technology, and discloses a wireless remote stored-grain temperature monitoring system with low energy consumption, easy maintenance, and multi-path acquisition. The invention is realized through the following scheme: the system comprises a wireless terminal system, a wireless network router, a wireless network base station, and a temperature monitoring server; the data acquisition wireless terminal is provided with a 15-path analog signal switch inside, and a temperature sensor transmits temperature data to the analog signal switch through a connecting wire; the data acquisition wireless terminal, the wireless network router and the wireless network base station perform bidirectional digital communication through a connector and a wireless radio frequency module. The invention solves the problem of wired network dependency of traditional stored-grain temperature monitoring systems, substitutes single-path temperature measurement with multi-path temperature acquisition, not only reduces communication cost and personnel labor intensity, but also improves timeliness and accuracy of temperature monitoring.

The invention discloses a floor heating structural body and a laying method thereof. The structural body comprises a hard thermal-insulation layer, a laying layer, a cable network, a reinforcement iron gauze, a ground decoration layer and a cement layer arranged between the hard thermal-insulation layer and the ground decoration layer in a filling mode. The layer method comprises the steps of stacking the hard thermal-insulation layer, the laying layer, the reinforcement iron gauze and the ground decoration layer in sequence; installing the cable network in the laying layer; and filling interiors of the laying layer and the reinforcement iron gauze with the cement layer. The floor heating structural body is orderly in wiring, and materials are saved; by the arrangement of the structural body and the cooperation of the corresponding laying method, the thickness of the structural body is reduced, use space is reduced, the heat efficiency is improved, the construction period is shortened, and the construction cost is reduced.

The invention discloses a method for switching among a plurality of network modes of an intelligent sideboard. The switching method is applied to the intelligent sideboard. The intelligent sideboard comprises a wired interface module and a wireless interface module. The switching method comprises the following steps: A, monitoring whether or not a wired signal is available on the wired interface module in real time; B, if the wired signal is available on the wired interface module, shutting down the wireless interface module, and processing the wired signal to realize wired communication; and C, if the wired signal is unavailable on the wired interface module, starting the wireless interface module, and processing a wireless signal received by the wireless interface module to realize wireless communication. Step A to step C are repeated. The invention also discloses an intelligent sideboard supporting the plurality of network modes. Through adoption of the method, switching between a wired network and a wireless network can be performed intelligently in real time according to a monitoring result.
