Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] figure 1 It schematically shows the network topology of the system for realizing the wireless communication between the instrument and the upper computer according to an embodiment of the present invention. Such as figure 1 As shown, the system includes a host computer 1, a slave device node 3 and a master device 2. The slave device node 3 is connected to the host computer 1 through the master device 2, and communicates with the host computer 1. The host computer 1 sends to the master device 2 through serial communication. Data request to slave node 1. Among them, the master device 2 and the slave device node 3 contain wireless modules, and the wireless network connection usually adopts a star structure, that is, a master device 2 can connect up to 16 slave devices for good wireless communication. In the embodiment of the present invention, the mast...

Abstract

The invention discloses a method and system realizing wireless communication between an instrument and a host computer. A host computer, salve unit nodes and primary devices are comprised. The salve unit nodes are connected to the host computers through the primary devices and carry out communication with the host computer. The host computer sends data requests for the slave unit nodes to the primary devices through serial port communication. The primary devices obtain response information from the slave unit nodes of the present groups through wireless modules, and respond to the data requests of the host computer through the serial port module. The invention also discloses a method realizing wireless communication between the instrument and the host computer. Through the system and the method of the present invention, communication can be carried out between the host computer and the instrument through the wireless transmission, so that troubles of wiring are reduced and the cost is saved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and system for realizing wireless communication between an instrument and a host computer. Background technique [0002] In order to better monitor and manage the power situation in the power distribution room, the upper computer generally needs to periodically read the data of each instrument in each power distribution room, including voltage, current, power and electric energy. The communication between the current power distribution instrument and the upper computer is generally connected by cables, which is costly and complicated to connect. Contents of the invention [0003] According to one aspect of the present invention, a system for realizing wireless communication between an instrument and an upper computer is provided to solve the problems of high communication cost and complicated wiring through cable connection in the prior art, realize wireless commu...
