Abstract. With the development of intelligent transportation, expressway toll station is more and more used electronic equipment, and electronic equipment constantly improve the degree of integration [1]. It also leads to the increasing lightning damage degree of expressway electronic equipment. Currently the expressway toll station although generally take the lightning protection measures, but there are still problems of lightning prevention. Therefore, we should strengthen the inspection and testing work on the expressway toll station lightning protection device, clear expressway toll station lightning detection of specific content, continuously improve lightning protection detection level, the installation of lightning protection device can play a effective role in the protection.
