Embodiment Construction

[0016] Such as figure 1 The block diagram of the HART hand-held device based on the smart phone is shown, including a smart phone 102 installed with a smart operating system (such as IOS, Android, Windows Phone), a memory card 101 equipped with HART configuration software, a wireless HART wireless communication interface 103 for communication function. The WIFI communication mode is adopted between the smart phone 102 and the HART wireless communication interface 103 . A standard HART communication protocol is adopted between the HART wireless communication interface 103 and the HART field device 104 .

[0017] Such as figure 2 The schematic diagram of the internal structure of the wireless communication interface is shown. The HART wireless communication interface 103 is composed of three parts: the first part is the HART communication channel, which is mainly used to transmit the HART digital signal, which is sequentially composed of the DC isolation module 206, the signa...

Abstract

The invention relates to a smartphone-based HART (highway addressable remote transducer) handheld operator and an implementation method thereof. The smartphone-based HART handheld operator comprises a smartphone with a smart operating system, a storage card with HART configuration software, and an HART wireless communication interface with a wireless communication function. The storage card is disposed in the smartphone. The smartphone is communicated with the HART wireless communication interface by means of WIFI (wireless-fidelity). The HART wireless communication interface is communicated with HART field devices through standard HART communication protocol. A user can communicate with HART field instruments conveniently with the smartphone which is widely popularized, and accordingly the handheld operator has the advantages of flexibility, portability, practicality, high cost performance and the like. A complete HART master station data link layer is built in the wireless communication face, so that the handheld operator is compatible with all HART field devices. Universal handheld operators meeting various fieldbus standards can be assembled flexibly and conveniently by changing different wireless communication interfaces.

Description

technical field [0001] The invention relates to an industrial control technology, in particular to a smart phone-based HART handheld device and its implementation method. Background technique [0002] As an open protocol, the HART protocol has now become the "de facto" standard for smart meters. Judging from the authoritative automation market analysis report in the United States, the demand for global intelligent instruments, especially those conforming to the HART protocol, is still increasing year by year. [0003] As a master-slave communication protocol, the HART protocol is divided into a master device and a slave device. The master device is the initiator of digital communication, and the slave device is the responder. HART protocol master equipment includes two types: the industrial PC system is the first type, which mainly realizes the real-time monitoring of the parameters and status of the on-site HART slave equipment; Adjustment and test maintenance, only acces...
