Demal Machine ETC Equipment Analyzing Circuit Design: All free installed ETC is garbage?

It is understood that ETC was originally cooperated with Beijing Capital Expressway Development Co., Ltd., Started trial operation in the Capital Airport Expressway in 1996. Since then, Guangdong, Beijing is the first to conduct ETC field tests. Thanks to the reform and opening of the dividend, Guangdong, Beijing, two places in Beijing, the number of vehicles in the 1990s, ETC became an alternative artificial innovation technology. Since the May 2019, the General Office of the Ministry of Transport is issued, "Notice on Promote the Development Application of Expressway", and the high-speed ETC (ie, no parking electronic toll system) began to be large. According to the plan, by the end of last year, the ETC installation rate of each province (district, city) is more than 80%, and the vehicle ETC usage of the highway has reached more than 90%, and the highway basically realizes non-stop charges. Immediately, a boom in installing high-speed ETCs was set off. By the end of last year, ETC users increased from 765,600 in a year to 19.2 billion. But in the face of the surge, the various technical drawbacks of ETC began to surface. There are many users who have encountered ETC contacts, toll system upgrades, replacement cards, recharge and other issues, they must run and even have a few trip to do, and it is better to take convenience to the artificial channel. It is understood that the current ETC design is still based on the initial technology, behind this chip card, what technical details can be excavated? Let's share a dismantling of an ETC product below. There is a button on the back, this is the same. There is also a button above back After opening This is a solar panel, charging the battery This should be a Bluetooth module I don't know what chip. New Tang's single-chip ARM Cortex M0 kernel Back chip Segment LCD screen As can be seen from the above dismantling, this ETC is actually a card reader, plus an RFID module, which is very low. ETC failure is because ETC defaults to special car dedicated, and there is a protection linkage when installing. If the button behind two times will cause the ETC electronic tag to fail, in addition, the OBU of the ETC card has a small button, if ETC The back is pushed to drop it from the front glass, and this small button will bounce down the label to fail. The solution is to go to the ETC business hall to detect activation, or the ETC installation point of the Highway Management is reactivated. Be Be The article is from the network finishing
