摘 要：目前市面上的專網(wǎng)通信終端一般都由公網(wǎng)終端改造而來，缺乏對(duì)于電力業(yè)務(wù)的安全、適配性等定制化開發(fā)，在一定程度上制約了電力無線專網(wǎng)的發(fā)展。研究了面向電力業(yè)務(wù)的LTE無線專網(wǎng)通信終端，使用SOM（模組定義系統(tǒng)）的系統(tǒng)架構(gòu)，針對(duì)電力業(yè)務(wù)需求，分別從硬件和軟件方面介紹了LTE無線專網(wǎng)通信終端的設(shè)計(jì)，實(shí)現(xiàn)數(shù)據(jù)采集、通信、安全、網(wǎng)管等功能開發(fā)。經(jīng)測(cè)試表明，設(shè)計(jì)的終端能承載各類電力業(yè)務(wù)，滿足電力LTE 無線專網(wǎng)的通信需求，具有廣闊的應(yīng)用前景。
關(guān)鍵詞：LTE；無線專網(wǎng)；通信終端；電力業(yè)務(wù)

Abstract: At present the private network communication terminal in market is reformed from the general public network terminal, which lacks of safety and suitability etc customized development for electricity power business, which to some extent, restricts the development of electric power wireless network. This paper studied the LTE wireless communication terminal for electric power business and used the system architecture of SOM (System on Module). According to the power needs of the business, this paper respectively introduced the design of LTE wireless network communication terminal from the aspects of hardware and software, together with data acquisition, communication, security, network management and other functions development. The test shows that the terminal designed can carry all kinds of power services, meet the communication requirments of the power LTE wireless network, and have a broad application prospect.
Key words: LTE; wireless special network; communication terminal; electric business
