Vehicle-mounted navigation test equipment and method based on environment monitoring

Abstract

The invention discloses a vehicle-mounted navigation test device and method based on environment monitoring. The vehicle-mounted navigation test device comprises a test device body, a vehicle machine, a display screen and a 4G5G antenna. The test equipment comprises a baseband chip, an MCU and an A / D module which are respectively connected with the baseband chip, a first coaxial interface and a second coaxial interface which are respectively connected with the A / D module, and a communication interface group which is connected with the MCU, wherein the communication interface group comprises a plurality of communication interfaces; the first coaxial interface is used for being connected with a navigation feeder line; the second coaxial interface is provided with a navigation satellite signal test end which is used for being connected with a navigation antenna or a navigation feeder line; the display screen and the 4G5G antenna are respectively connected with the vehicle machine; and the vehicle machine is connected with the test equipment through one communication interface. According to the invention, the performance of the vehicle-mounted navigation system can be detected in environments of different positions, weather, time and the like; when the navigation performance is insufficient, the problem point of the navigation system can be quickly judged.

Description

technical field [0001] The invention belongs to the technical field of testing, and in particular relates to a vehicle navigation testing device and method based on environmental monitoring. Background technique [0002] With the widespread application of in-vehicle navigation systems, users use in-vehicle navigation more and more frequently. The accuracy and response time of the navigation system are particularly important in use. If the navigation accuracy is not accurate, the navigation positioning will be deviated. If the navigation response time is slow, the navigation information will be delayed and the navigation route will be deviated, which will seriously affect the normal use of users; For car users, they completely rely on the navigation system to locate orders and settle bills. If the navigation is not allowed, the vehicle will not be able to operate. Due to the large number of components involved in the navigation system, there is currently no fast and effectiv...

Problems solved by technology

The accuracy and response time of the navigation system are particularly important in use. If the navigation accuracy is not accurate, the navigation positioning deviation will be caused. If the navigation response time is slow, the navigation information will be delayed and the navigation route will be deviated, which will seriously affect the normal use of users; especially for operation For car users, they completely rely on the navigation system to locate orders and settle accounts. If the navigation is not correct, the vehicle will not be able to operate.

Due to the many components involved in the navigation system, there is currently no fast and effective offline testing method for the navigation system. Often, after the vehicle enters the market and there is a problem in the user's use, replacement parts are required, which will bring unnecessary economic losses and brand image loss
