Description

Electronic map communication device based on GPS global positioning system and application

The present invention relates to the field of electrical communications, and in particular to an electronic map communication device and use based on a GPS global positioning system.

Background technique

With the rapid development of communication technology, a system combining GPS and electronic maps has appeared, and its purpose is to provide users with satellite navigation. At present, most GPS is implemented by hardware, and its expensive price makes it difficult to promote applications. At present, most of the electronic maps are to digitize the published maps again, and their products are one-dimensional. Therefore, the accuracy of such electronic maps is not enough. When accurate navigation is required, such electronic maps simply cannot meet the requirements. Although foreign GPS products with expandable map modules have been used, their high price and the special nature of national map management in various countries in the world have greatly restricted the application of these products in China. Another noteworthy issue is that PDA products are developing rapidly, and people are increasingly interested in PDA products. The handheld computers in PDA products have become the focus of attention because of their fast and flexible functions and easy to carry. However, most of the existing handheld computers only have functions such as a memo, a dictionary, and an address book, which cannot meet people's increasing demands for communication, and cannot provide satellite navigation functions.

China, "Communications" magazine, the January 2002 edition published an article called "PDA Magic", which announced several kits for PDAs. The handheld computer can be turned into a mobile phone by inserting the phone module kit into the socket ₇ on the back of the handheld computer; the handheld computer can be equipped with satellite navigation function by inserting the handheld computer into the navigation module kit. However, this method of configuring a handheld computer to add functions to the handheld computer, although the handheld computer has a communication function and a satellite navigation function, still has many disadvantages. First, the handheld computer and its kit are separated from each other, which is not easy to carry and easy to lose; the kit and the kit are independent of each other and each has only a single function. The kit must be connected to the handheld computer when in use (that is, to occupy the communication of the handheld computer) Interface) to complete the required functions, which results in a waste of resources; furthermore, the price of the kit is relatively expensive, which is not conducive to popularization. At present, most people call the police in an emergency situation by telephone (including a mobile phone). However, the disadvantage of a telephone alarm is that it takes a certain amount of time to explain the cause of the alarm and the location of the incident on the phone. However, in an emergency Time is often not allowed, even dialing time is not allowed. Even if there is time to explain the place of the crime, it will take a certain amount of time for the police to find the exact place of the crime based on phone records only. These exist in emergency situations. The disadvantages of the alarm method sometimes cause losses that could have been avoided. So how to solve the emergency alarm problem is in front of people.

In real life, people often encounter such situations. In an unfamiliar city, in the field, or in scientific research, they often need to know their location because they are lost, or they need to know the best route to their destination. Satellite positioning systems can help people solve this problem, but existing satellite positioning systems are expensive and cannot be widely used. Therefore, how to provide a widely applicable navigation method is in front of people.

At present, topographic mapping, especially in real estate, is close to people's lives. However, most of the existing mapping methods are extremely professional mapping methods, and the mapping tools are complex, and corresponding human support is required when mapping, so how to provide a The convenient method of surveying and mapping is a problem to be solved.

Police often need the information support of the police center when performing police affairs, and sometimes even the emergency rescue of the police center. At the same time, the police center also needs to know the situation of the police officers or issue orders to the police officers. At present, most of them use walkie-talkies to Do the work. However, there are many disadvantages to using walkie-talkies. First, the walkie-talkie can only talk, but cannot transmit text and image information, and it does not have navigation and positioning functions. Moreover, the talk range of the walkie-talkie is difficult to use in large areas. The police sometimes need to identify fingerprints when performing police tasks. However, the existing portable fingerprint identification equipment is not only bulky and expensive, it is not easy to carry, and it must be operated by professionals. Therefore, how to provide the police with a multifunctional, convenient carrying and operating, and affordable communication device is also a problem to be solved. Summary of the Invention
