Background technology

Mobile access equipment is a kind of communication apparatus that is used for the wireless access the Internet, can support the GPRS under the GSM network, CDMA 1X, WCDMA, CDMA2000 and the TD-SCDMA etc. under the support cdma network.Mobile access equipment is as a high-speed data treatment facility, by wireless mode with transfer of data to subscriber computer.The use of mobile access equipment makes the mode of user Internet access or public security private network become easier.Mobile access equipment can make the online save time, laborsaving, province's expense.

Common mobile access equipment is a kind of radio network gateway, and it does not have routing function, can not link to each other with many computers, and security performance and poor safety performance can not satisfy the access standard of public security private network.

Global position system comprises GPS or big-dipper satellite navigation system etc.Global position system is quite ripe through years of development, but also can only provide positional information, does not have the function that information and transmission information initiatively are provided, and can not carry out telecommunication with computer.

The utility model content

The purpose of this utility model just provides a kind of alert mobile access equipment of using with location and communication function, the information of local computer is inserted the Internet or public security private network whenever and wherever possible with realization, realize the alert information fast query of using, simultaneously also can be to the alert locator data of the circular of the main frame on the Internet or the public security private network with mobile access equipment geographical position of living in.

The utility model is achieved in that a kind of police with location and communication function uses mobile access equipment, includes:

The CPU module is used to carry out data processing;

Ethernet interface joins with the CPU module, is used to connect local computer, realizes the wireless Internet access of local computer;

Communication module is joined with the CPU module, is used to realize the wireless telecommunications between local computer, locating module and the Internet or public security private network;

Locating module joins with the CPU module, by with the communicating by letter of CPU module, locating information is transferred to the CPU module, relend and help communication module that locating information is connected into the Internet or public security private network;

Encrypting module joins with the CPU module, is used for the police who is transferred to the Internet or public security private network is encrypted with information; And

Power module joins with above-mentioned each module, in order to vehicle-mounted 12V voltage, converts the required voltage of each module chip to.

Locating module in the utility model is transferred to the CPU module with the locating information that receives, relends to help Ethernet interface to be transferred to local computer, thus the navigation feature of realization police car; Locating module receives locating information and is transferred to the CPU module, imports information into the Internet or public security private network by communication module, thereby realizes the unified scheduling to police car; The information of local computer is transferred to the CPU module via Ethernet interface, and the CPU module is connected into the Internet or public security private network with information by communication module again, thereby realizes the communication function of local computer.

The utility model all passes through the encryption of encrypting module to the police service information that is transferred to network, has guaranteed transmission safety of data and reliability thus.The access standard that the encryption of communication information is met Ministry of Public Security's encryption standard and public security private network.

Described communication module is for supporting the GPRS of GSM network, or supports among CDMA1X, WCDMA, CDMA2000 and the TD-SCDMA of cdma network any one.

Described locating module is supported GPS or Beidou satellite navigation system.

In described power module, be provided with super capacitor, can be implemented under the flame-out situation of vehicle the communication and the location that keep police car.

The utility model is a kind of brand-new alert mobile access equipment of using with dial feature, routing function and positioning function, can insert many playscripts with stage directions ground computer, making local computer need not dialing can link by this equipment and the Internet or public security private network, and, also can send the residing position of this mobile access equipment to the main frame on the Internet of appointment to local computer transmission GPS global location or Beidou satellite navigation locator data.

The utility model is installed on the police vehicle, and the computer on the police car is linked to each other with this access device by netting twine, so just can insert the public security private network; Locator data sends on the local computer, can realize navigation feature, helps the user to arrive the destination smoothly; The positional information of police vehicle (longitude, latitude, height above sea level etc.) can be transferred to public security command center by this mobile access equipment, with clear and definite vehicle location, is convenient to timely scheduling.

The utility model combines positioning function with mobile communication (GPRS, CDMA 1X, TDS-CDMA, WCDMA, CDMA2000), can be navigation system (GPS or big-dipper satellite navigation system) provides the approach of transfer of data, has broken through the development bottleneck of global position system thus.The utility model stable performance, power is little, and power consumption is low.

Below in conjunction with accompanying drawing the utility model is further described.

Description of drawings

Fig. 1 is a structured flowchart of the present utility model.

Embodiment

As shown in Figure 1, the utility model adopts modularized design, is connected to form by CPU module 1, Ethernet interface 2, communication module 3, locating module 4, encrypting module 5 and power module 6.

Wherein CPU module 1 is being served as the role of data processing, is the data processing core of this mobile access equipment.The information of local computer is transferred to CPU module 1 by Ethernet interface 2, and CPU module 1 is imported the information of local computer into the Internet or public security private network by communication module 3.Communication module 3 receives the network information through wireless network, is transferred to CPU module 1.

Locating module 4 is transferred to CPU module 1 with the satellite-signal that receives, the satellite-signal that CPU module 1 receives locating module 4 is passed to communication module 3, send into the Internet or public security private network, so just the satellite location data signal that locating module 4 is received is connected into the Internet or public security private network.The satellite-signal that locating module 4 receives is given CPU module, relends to help Ethernet interface 2 to give local PC 1, just can realize the navigation feature of police car.

The effect of Ethernet interface 2 is to realize communicating by letter of CPU module 1 and local computer, thus the communicating by letter of realization local computer and the Internet or public security private network.

For stability and the reliability that satisfies public security system, this mobile access equipment also is provided with encrypting module 5, this module satisfies the encryption mechanism of the Ministry of Public Security. and encrypting module 5 links to each other with CPU module 1, the information that externally sends is encrypted, again message transmission is arrived communication module, send to the public security private network, to guarantee safety of data.

Because the supply power voltage of system can not satisfy the requirement of the utilization voltage of all chips of system, so need supply power voltage to be converted to the needed magnitude of voltage of each chip of system under certain condition, be provided with a power module 5 for this reason especially, utilize power module 5 to provide required operating voltage for each module of system; This module also is provided with super capacitor, can be implemented under the flame-out situation of vehicle the communication and the location that keep police car.
