Embodiment

[0069] The handheld device needs to establish a wireless connection with the designated device to complete the configuration and obtain device information. According to different situations, handheld devices use two different ways to communicate with the device:

[0070] The first way: such as figure 2 As shown, the handheld device H1 establishes a point-to-point subnet with the designated field device N2. Once this point-to-point subnet is established, the handheld device will be regarded as a trusted device, allowing it to conduct secure point-to-point communication with the field device N2. Since no other routing equipment is required to participate in the data transmission, the use of link layer encryption can ensure data security. The process of establishing a point-to-point secure communication subnet is as follows:

[0071] 1) The user of the handheld device H1 enters the configuration key and starts the configuration software after success;

[0072] 2) The handheld device ...

Abstract

The invention relates to a high-safety multi-level encryption and authentication type WIA-PA network handheld device communication method. The WIA-PA network includes a gateway, a routing device and a field device. The handheld device can be in safe communication with devices in the WIA-PA network in two ways. In the first way, point-to-point communication is established between the handheld device and the devices in the WIA-PA network, and encryption is performed in the link layer. In the second way, the handheld device is joined into the WIA-PA network, and the handheld device is in communication with the devices in the WIA-PA network through the multi-level encryption technology after the handheld device is joined into the WIA-PA network. Through the combination of the two ways, the safety can be ensured, and at the same time, communication is fast established between the handheld device and the devices in the network, and advantages of low power consumption, fast speed and less network performance influences can be realized.

Description

Technical field [0001] The present invention relates to a secure wireless communication technology, in particular to a handheld device and an operation mode that allows the handheld device to perform secure communication with a device selected in a WIA-PA network. Background technique [0002] Industrial wireless network WIA (Wireless Networks for Industrial Automation) technology is a highly reliable, ultra-low power intelligent multi-hop wireless sensor network technology with independent intellectual property rights launched by the Shenyang Institute of Automation, Chinese Academy of Sciences. This technology provides a self-organizing , The self-healing intelligent Mesh network routing mechanism can maintain high reliability and strong stability of network performance in response to dynamic changes in application conditions and environments. [0003] Industrial wireless networks have begun to be used in important fields such as electric power, petroleum, chemical engineering, a...
