Description

1221717 —— ~ — V. Description of the invention (U ’s invention provides a global positioning system transmitting and receiving device, especially a transmitting and receiving device wheel control / network communication protocol to transmit the corresponding coordinate background information. The establishment of the Global Positioning System (g 1 0ba 1 GPS) is mainly in response to the development of military use, positioning, or missile navigation and positioning, etc., and it has been commonly used in general positioning systems, which mainly include a plurality of positioning satellite controls. center), and a user including the distance from the star system to the most orbiting earth. According to this rule, the monitoring system of each star can be used to manage the system map 1. Map system 10 is included in the earth ’s mission. Each time it is used to manage the positioning, position, and speed, three-digit operations must be received. Because it is currently commonly used in the navigation and vehicle management system function block diagrams to transmit positioning satellites for 12 hours, satellites, and so on. Positioning satellites and navigation systems and navigation systems. Please refer to the position system of management, such as ships in the ocean, and with the global positioning system in the lives of the general public. Global satellite, a ground control center, this positioning satellite is a positioning signal that distributes data. Generally, there are at least 24 positioning satellites. The ground control center is a high-level positioning satellite transmitted by the satellite, and the positioning signal of the user can be provided to determine the position of the user terminal. For example, the vehicle navigation system is a control center 1 of the conventional management system 1 2 and — 1221717 V. Description of the invention (2) The client terminal 14 is the target that the control center 12 wants to manage, such as a vehicle, and the client terminal 14 will receive the transmission from the positioning satellite 16 The positioning signal 18 is calculated, and then the coordinates are calculated through the positioning signal 丨 8, and then the coordinates are transmitted to the control center 1 2 ', so the control center 12 can know the current position of the user terminal η. The operation of the management system 10 is detailed below. The user terminal 14 includes a receiving antenna (gps antenna) 20, a global positioning system module (GPS m0du 1e) 2 2, a computer system 24, a wireless communication module 26, and a communication antenna 28. The control center 12 includes a communication antenna 30, a wireless communication module 32, and a computer system 34. The receiving antenna 20 is used to receive the positioning signal 18 transmitted by the positioning satellite 丨 6 and transmit the positioning signal 18 to the GPS module 22, and the GPS module 22 calculates the positioning signal 18 In order to obtain the latitude and longitude position of the current user terminal 4. The computer system 24 is used to control the operation of the client terminal [4] to coordinate the operation of the internal components. When the computer system 24 receives the coordinate data output by the client terminal j 4: it further transmits it to the wireless communication module 26. The wireless communication module 26 is a mobile phone module and is applied to a mobile phone system. For example, the mobile phone system (glObal) uses ㈣ίπ mobiU 1 (T, GSM) to transfer the coordinate data of the user terminal 14 2 8 pass to two a 10 2equency) signal 36, and set the communication center through the communication antenna. In addition, the user terminal 14 and the control center 12 are 36, and the system 2 (not shown) is used to Following the transmission of the RF signal to the phase = the antenna 30 will receive the RF signal 36 and transmit the corresponding wireless communication module 3 2. The wireless communication. The communication module 32 will process the radio signal.

Page 6 1221717 V. Description of the invention (3) Frequency signal 36 to obtain the coordinate data of the client 1 and 4 and transmit it to the computer system 34 for storage or further processing. For example, if the library logo data of the client 4 is The wireless communication module 2 6 of the client 1 4 is converted into a voice signal. Then the wireless communication module 32 of the control center 12 will separate the coordinate data (longitude and latitude signals) of the client 1 4 from the voice signal, and then send it. Smart computer system 34. Similarly, if the coordinate data of the client terminal 14 is converted into a message via the wireless communication module 26 of the client terminal 14, the wireless communication module 32 of the control center 12 will directly The newsletter is transmitted to the computer system 34 '. Therefore, the control center 12 can obtain the latitude and longitude position of the client terminal 14. In addition, the computer system 34 of the control center 12 can execute a geographic information system (G IS), and the brigade displays the current position of the client 14 on a corresponding map according to the latitude and longitude position of the client 14 In the same way, the computer system 24 of the client terminal 14 also implements a geographic information system, and the map position is directly displayed on the client terminal 14. As mentioned above, the client of the knowledge management system 10 uses the global positioning system to obtain its coordinate data, and transmits the coordinate data to the control center 12 through the known digital mobile electrical activity system. As far as the mobile phone system is concerned, it uses a cellular base station as a network and can perform digital signal transmission. 'So in addition to telephone communication, you can also enjoy the advantages of digital services.' However, the digital mobile phone system must be a user The terminal 14 establishes a communication channel with the control center 12 so that the client 14 can successfully transmit its coordinate data to the control center 丨 2, that is, during the communication period, the communication channel is only for the client 14 and the Control Center 1 2 occupied because

1221717 V. Description of the invention (4) This will occupy a part of the bandwidth of the conventional digital mobile phone system, and the communication cost will be low, and the client terminal 1 will regularly transmit its coordinate data to the center 1 2 ', which cannot be reached. Real-time (r ea 1 ti me) processed α. If real-time processing is performed, the data transmission of the knowledge management system will be greatly improved. In addition, the client terminal 14 and the control center 12 are transmissions of (pier-10-Pier), and the client terminal 14 and the control must support the conventional digital mobile phone system at the same time. When the client terminal inputs its coordinate data to At the other control center 12, the user terminal 14 must re-establish the connection with the control center 12, so when multiple coordinate data of the same user terminal 14 are in control, the connection between the user terminal 4 and each control is established. Will make the implementation of the knowledge management system 10 poor. In other words, the client terminal 14 uses an industrial computer (I PC) architecture, such as an embedded single board computer, which has a large volume and consumes a lot of power and costs more. In addition, it is only used for receiving The positioning signal 18 and the positioning signal 18 conversion center 12 are stored instead of being stored in the client terminal 14 at the same time. Because the user of t 1 4 cannot obtain the relevant department from the client terminal 14 itself, The invention is described so that the book is sent to the control center. The cost of loss is 12 points for the snack 12 and the other 12 needs to be managed by the center. 12-General but lost. However, the client terminal 1 4 is sent to the controlling user. As a result, it is transmitted to the control center 12, so the coordinate data will be transmitted to the funding department, that is, the coordinate data cannot be analyzed by the client 1 4. The client 1 4 cannot exchange coordinate data with another computer system. Inconvenient to use.
