Problems solved by technology

Therefore, products that fully comply with the IEEE 802.15.4 standard will have limited application in the power industry; currently, products with a star network structure such as data transmission stations using dedicated frequency points for power are commonly used in the power industry, and because they do not have IEEE 802.15 .4 The technical characteristics of the data link layer have been difficult to meet the needs of the wireless network structure for the information development of the modern power industry

Embodiment Construction

[0009] See the accompanying drawings, namely (1) 16-bit MCU (single-chip microcomputer), (2) EEPROM (electrically erasable read-only memory), (3) RF (radio frequency) chipset, (4) DSSS (direct sequence spread spectrum) RF Chipset, (5) PA / LNA (power amplifier / low noise amplifier), (6) crystal oscillator. The specific instructions are as follows:

[0010] (1) 16-bit MCU (16-bit microcontroller)

[0011] 16-bit microcontroller controls the entire system, including controlling serial communication and wireless communication. Based on its built-in MAC (Media Access Control) protocol, it controls all control signals and information programs of wireless communication. Electrically Erasable Read-Only Memory (EEPROM) is connected to the microcontroller to store data from the microcontroller. The main purpose of EEPROM is to store and buffer long data streams between UART (serial communication interface) and RF, which can ensure more robust communication functions.

Abstract

The provided network wireless module of electric sensor comprises: sealing the electric element fit to data link layer as part of IEEE 802.15.4 standard and the physical layer for electric special frequency point into one module also comprised a RF chip, a data link layer chip, a SCM and assist device. This invention is benefit to remote operation, and breaks limit of former standard with much better performance-price rate for wide application.

Description

technical field [0001] The invention relates to a wireless module of a sensor network, in particular to a wireless module of a sensor network which can dynamically adjust the network structure by using wireless frequency points allocated by the electric power industry to form intelligent instruments. Background technique [0002] In this article, the sensor network specifically refers to a wireless network that conforms to the IEEE (Institute of Electrical and Electronics Engineers: Institute of Electrical and Electronics Engineers) 802.15.4 standard. Its main technical feature is to support dynamic changes in network topology, derived from the definition of the data link layer in the standard. Compared with the wireless networks with fixed structures such as stars in the past, it has obvious technical advantages. [0003] The wireless frequency band allocated by China's power industry is 200-240MHz, which is not included in the physical layer standard defined by IEEE802.15...
