佛山车载终端794认证周期多久

After the platform software developers and GPS equipment developers have installed the standard development, they need to pass the Ministry of Transportation’s Ministry of Transport’s Ministry of Standards inspection and certification, and then they can participate in the software and hardware bidding in various places.
The function test of the platform by the Ministry of Transport mainly simulates the GPS terminal sending standard protocol data, and then tests whether it can receive the data correctly. Developers of GPS applications must understand and master these protocols. The platform protocols are mainly JT/TB808, 809 and extended supplementary protocols. At the same time, the protocol also applies the ministry-promulgated GB19056 standard for the driving recorder. /T796 is mainly a standard for hardware equipment, you can refer to it.

部标794认证办理难度大不大?
答:新版的交通部运输行业标准其实比原先的老标准还更加严格，增加了不少检测项目。部标794认证主要会测试产品的硬件和软件，也别是软件方面，如果你的产品软件功能不能满足要求的话，那么肯定是过不了这个认证的啊。有些企业送检了大半年都没有通过的我经常听到这样的例子的。所以，部标794过检的难度挺大的。

部标794过检不通过怎么办啊？
如果送检不通过的话需要再现场去整改的。一般都是需要安排的技术人员在现场跟着技术中心一起测试才可以的。在现场需要差不多一个多月的时间。不通过的话需要整改到通过才行，如果反复测试不通过的话就会额外产生费用的。
