The above-mentioned information service system is an information reporting system among one or more user terminals, one or more information service servers, and one or more equipment terminals. The information service server disclosed by the present invention is connected to remote equipment through a network (preferred embodiment is the Internet), and the equipment end has the ability to connect to the network. ) terminal equipment can be directly connected to the Internet; the second terminal equipment does not have the ability to connect to the Ethernet network can be connected to the Internet through a network device. The terminal equipment can transmit information to the information service server through the network for information reporting, and the user can perform monitoring by logging into the information service server.

Please refer to the architecture diagram of the information service system applied to the information transfer method of the information service server of the present invention shown in Figure 3, wherein each terminal device is all connected to each other through a network 30, and the network 30 can be the Internet, an intranet (Intranet), Virtual private network (virtual private network, VPN) or local area network (LAN) of other wired or wireless structures, this information service system includes the information service server 31 that has networking ability and connection various terminal equipments, other terminal equipments include online A plurality of digital video recording devices (Digital Video Recorder, DVR) 34, 35, 36 of the network 30, such as a network video recording device (Network Video Recorder, NVR) 37 of the online network 30.

For example, the above-mentioned digital video recording device (DVR) 34 is further coupled to one or more terminal devices. If a switch (switch) 341 is connected to the digital video recording device 34 through the network, the digital video recording device 34 can also use a cable (cable) Or other physical lines are coupled to the PTZ camera 342 with functions of panning (Pan), tilting (Tilt) and zooming (Zoom).

In another embodiment, the above-mentioned digital video device 35 can be connected to a general camera 351 by a cable or other physical lines, and for another example, the digital video device 36 can be connected to an IP camera (IP camera) 361 through a wireless or wired network.

The aforementioned network video recording device (NVR) 37 with network transmission function can also be coupled to the general camera 371 .

The preferred embodiment of the above-mentioned terminal equipment with information transmission function is such as the above-mentioned multiple digital video recording devices 34, 35, 36 or network video recording devices 37, each terminal device is directly connected to the information service server 31 provided by this system through the network 30, If the user wants to obtain the information or data of each terminal device, he needs to connect to the information service server 31, and after performing the security login operation, utilize the web browser 33 at the user end or the information provided by the information service server 31 to install on the user. The application software 32 of the terminal computer performs data access, and the information service server 31 can use various graphic interfaces to provide a more humanized monitoring environment such as reports, status display, device control, and settings.

The monitored or managed digital video recorder (DVR) and network video recorder (NVR) described here, or other video servers (Video Server) can be connected through physical lines (video cables, power lines or network lines) ) to connect different monitored devices, such as cameras (351, 371), network cameras (361), PTZ cameras (342) (which can control the left and right, up and down or far and near zoom control), access control system (not shown in the figure), power supply switches etc., the actual implementation is not limited to the examples described here. Because the information service server 31 controls each terminal equipment through devices such as DVR, NVR or various image servers, the information service server 31 does not need to deal with related control processes such as how to control the monitored equipment connected after each device.

In this embodiment, the network 30 is a broadly defined network, including lines connected by various cables. For example, a digital video recorder (DVR) needs its own cable, while a network video recorder (NVR) has its own cable. Set up multiple cameras online on the network (determined according to the screen update speed and available broadband). In addition, if there is a general analog camera, it can also be used with a video server (video server) through a wired or wireless network to replace the digital video device (DVR) for image digitization.

Fig. 4 is one of the embodiments of the application of the information service server of the present invention, which shows a schematic diagram of the connection relationship between the information service server and each terminal device, and the information service system shown in the figure consists of one or more user terminals ( 43, 47), one or more information service servers 41, and one or more equipment terminals (45, 49). This embodiment takes the connection of the Internet 40 as an example, and each end has the connection capability of the network, such as The information service server 41 is connected to the Internet 40 through network communication protocols such as TCP/IP; the user 47 utilizes a computer 43 to connect to the Internet 40, and can access data in the information service server 41 through a secure connection; Terminal equipment without network connection capability, such as camera 401, access control 403, cash register 405, etc. in the figure, is connected to the Internet 40 through a network device 45 with network connection capability, and communicates with the information service server 41 The connection is made to provide the information of each terminal equipment; and the terminal equipment with network connection, such as the network camera 49 in the figure, can directly connect to the Internet 40, and then reach the connection with the information service server 41.

Each of the above-mentioned devices or servers connected to the network must have its own unique identification method, such as using the unique media access control address (MAC address) on the network as the identification data on the network, or the network address (IP address) of each device ), so as to identify each device on the network, because the network address may change through NAT (Network address translation) and VPN conversion, so the preferred embodiment is based on the MAC address.

The method for the information service server 41 to retrieve the information of each terminal device through the driver program has the following two driving modes, except for some various standard information that has been regulated by the network:

(1) Install relevant driver modules (or programs) of each terminal equipment in the information service server 41, which can provide more detailed and useful information. For example, the equipment manufacturer provides specifications, and the information service server is loaded with the device Driver module (or program);

(2) Add the drivers or related modules for the information required by the information service server 41 in each terminal device, and generate the information required by the information service server 41 actively by each terminal device, in order to be able to produce more useful information For example, the information service server 41 provides the control interface specification to the device manufacturer, so that the device also contains a driver module (or program) that conforms to the control interface specification.

The above-mentioned devices such as cameras 401, access control 403, and cash registers 405 without network connection capabilities may not have unique MAC addresses, but they can still be connected to the Internet 40 through a network device 45 with network connection capabilities. The device 45 can identify the connected terminal equipment through other identification methods, such as using various proprietary drivers to identify or hardware identification codes. If the network device 45 needs further information on each terminal device, it can also be provided with a driver or a related module for each device, and the information service server 41 can retrieve more useful information through the network device 45 .

For the network camera 49 (not limited to this) that already has a network connection, the information service server 41 can directly retrieve more useful information in the network camera 49 through the network, or carry out the control and setting of the device.

In the information service system of this terminal equipment, in addition to the standard transferable network packets, more information can be generated through additionally installed proprietary drivers. What's more, when the user 47 logs in the information through the computer 43 and the Internet 40 When serving the server 41, the behavior of each terminal device can be controlled through the control interface, such as controlling the shooting of the camera, performing power control of each device, and remote repairing. In a preferred embodiment, the information service server 41 can provide various graphic interfaces to generate reports, analysis, and control interfaces to achieve an easier and more convenient monitoring environment.

After the information transmitted between the terminal device and the information service server is classified, the classification of each information can be divided into various types according to its importance. The preferred embodiment is based on the information in the information packet (such as according to the value of the event code) Differentiate each information packet into: (1) real-time (real-time) information; (2) near real-time (nearly real-time) information; (3) emergency (critical) information; and (4) general record (log).

In addition, the various classifications can be planned on the information service server and each terminal device, and finally sorted according to the priority of each information, and then delivered sequentially. Each information packet is divided into real-time, near-real-time, urgent or general records according to the information conveyed by the above-mentioned event codes. And preferred embodiment is as follows:

(1) If the information is classified as real-time information, when the status changes or an event occurs, the terminal device immediately transmits the information, and requests that as long as the information is retrieved, it will be sent to the information service server, or displayed to the user in real time;

(2) If the information is classified as near-real-time information, when the state changes or an event occurs, the information will be temporarily stored and sent to the information service server periodically, that is, the terminal device will send the information to the information service server regularly, or It is regularly displayed to the user;

(3) If the information is classified as emergency information, that is, if important or error information occurs, immediately increase the priority and transmit information, such as system error information, operating status error, or abnormal operating environment, which may damage the equipment In addition to transmitting such information in real time, it can cooperate with the warning screen, light signal and sound on the system to transmit such information;

(4) If the information is classified as a general record, it is sufficient to record such information in the database of the information service server for future inquiries.

It is worth mentioning that when the above-mentioned real-time information (1) and emergency information (3) occur, the event information will be sent to the information service server immediately. If the current transmission fails, the content of the transmitted information will automatically Resend a specific number of times, if the resend still fails, the event information notification will be discarded, but the complete event information content can still be found when querying device events, such as general records; and the above near real-time information (2) It is not necessary to transmit information in real time. If the current transmission fails, the content of the transmitted information will be automatically delayed until the next transmission. If the same information cannot be successfully retransmitted several times, the event will be discarded. Information notification, but when querying device events, you can still find the complete event information content (for example, the record is a general record).

As mentioned above, the information classified according to the importance will be transmitted by the packet on the network, that is, the content of each information and its timestamp (timestamp) are recorded in the packet transmitted by the terminal device to the information service server, as shown in the packet shown in Figure 5 Schematic diagram of the format, which mainly includes the part of the header 500 and the part of the information data 511, and the fields in the header 500 include at least: (1) the host address 501, such as the information service server set on the terminal device Address; (2) identification code (ID) 502 of terminal equipment or network equipment, such as the model number (modelnumber) of each terminal equipment; (3) network address 503, such as the IP address of each terminal equipment; (4) information form 504, Such as indicating that the packet information is unencrypted text: text/plain; (5) packet length 505; (6) MAC address 506, recording the MAC address of the terminal device; (7) time stamp 507, matching the time, and recording it on the terminal device The result of the hash operation of the manager account of the set information service server; (8) In addition, there is an event code 508, which indicates what kind of information this packet is with a combination of multiple bits; (9) Other information 509, records other possible information, including the type of communication protocol, decryption method, port number, alarm signal, setting information, etc. of the packet.

In addition, the authentication information/packet between the device and the information service server is a one-way non-reversible encryption method. Even if the packet is captured by a third party, the original information cannot be reversed. This part can be hashed (hash ) algorithms (such as MD5) add data (such as device identification codes, user accounts, time stamps, etc.) into digital calculations to generate irreversible hash values, such as equation 1:

Hash value = hash("MAC address" + "user account") + timestamp

---------(1)

This hash value requires a lot of time and calculations to decipher, and the encryption method will also be changed regularly to ensure the most secure data transmission.

The terminal device will transmit the authentication packet (including at least MAC address, time, registration data, user account and other information) to the information service server, that is, send the relevant information of each device (such as the authentication packet) to the information service server ( Step S805); After the information service server receives each authentication information (step S807), it will perform authentication, and the main embodiment is to compare the data registered in the database by each terminal device (step S809);

After confirming the registration data of the terminal device, the authentication is completed, and the information return mechanism of the information service system is started, and the terminal device immediately sends status information to the information service server according to the occurrence of the event (step S811); if the authentication fails, it means that the If the information in the transmitted authentication packet is wrong, immediately feed back an error authentication information to the terminal device to confirm that the authentication has failed, or the terminal device can re-transmit a specific number of times within a specific period of time until the authentication succeeds, or declares a failure.

Please refer to FIG. 9 again, which shows the flow chart of the information service server of the present invention to start or stop information reporting to the terminal equipment.

The terminal device has the function of information transmission, and sends a request to the information service server through the network to start or stop information reporting. The steps start from the user logging in to the information service server, and the information service server executes the authentication step to confirm the user's authority. (step S901);

Select the terminal device to be controlled through the interface provided by the information service server, and the user enters the control interface (user interface) of the terminal device (step S903);

At this time, the information service server establishes a channel with the selected terminal equipment (step S905); the user executes the command of starting/stopping the service through the control interface, that is, transmits the command of starting/stopping the service to the terminal equipment through this channel (step S907);

Afterwards, the terminal device then requests the information service server to start or stop the service according to this instruction, sends a start/stop service request packet, and receives the start/stop service request packet by the information service server (step S909), after The information service server confirms that the source device is correct through the information in the request packet, and confirms the instruction of starting or stopping the service (step S911), and then transmits the confirmation information of starting or stopping the service to the terminal device (step S913), and the terminal The device starts or stops reporting information to the information service server immediately or according to the time set by the user (step S915).

Through the management of user accounts, the information service server grants different permissions according to the user's identity, which can be roughly divided into two identities: "manager" and "general user". The authorization scheme reached with this information service system can specify a The administrator account, and the authorization scheme can set multiple general users, and the setting and establishment of general users are established and managed by the administrator. After the user enters the interface provided by the information service server, he will view/manipulate the information provided by each terminal device, such as the image captured by the video recording device, through this interface according to the related authority settings set by the administrator.
