Description

Technical Field

[0001] The utility model relates to the technical field of signal simulation, in particular to a signal simulation device. Background Art

[0002] The GPS positioning system can provide global users with low-cost, high-precision navigation information such as three-dimensional position, speed and precise timing. It is also the most widely used positioning system in the world. In order to improve the accuracy of GPS, it is necessary to use a signal simulation device for testing. Among them, the "weak signal simulation device" disclosed by the application number "CN212364809U" has solved the various drawbacks of using uncertain equipment for medical or other work, which is quite irresponsible and easily causes loss of life or property. After further search, it was found that the " A "satellite navigation signal simulation device", through a specific technical structure setting, effectively solves the problem that in order to use the timing function of the satellite navigation system, the navigation signal must be received through an antenna, but the cost of setting up the antenna and the subsequent maintenance cost are relatively high, which is particularly obvious in remote mountainous areas and places with harsh climates. However, in actual use, signal simulation devices with similar structures still have many defects, such as: the existing signal simulation device has a single function, it is not convenient for users to observe the signal when in use, and the structure is simple, which is not convenient for users to debug the signal simulation device, so it is necessary to design a signal simulation device. Utility Model Content

After the connecting bolts are passed through the top cover, the top cover and the connecting rings can be connected by rotating the connecting bolts, which increases the sealing of the top of the shell and prevents the top cover from falling off during use.

[0010] Preferably, a protective door is movably mounted on the bottom box surface at the front end of the storage cavity, and a buckle is fixedly mounted at the front end of the protective door. After the protective door is opened by the buckle, the user can conveniently take out and store the items stored in the storage cavity, so that the user can use the device conveniently.

[0011] Preferably, a box door is movably mounted on the bottom box surface at the front end of the inner cavity, and a handle is fixedly mounted at the front end of the box door.
