  However, in order to construct such a system, it is usually necessary to install an ADSL router, a personal computer or a device corresponding to a personal computer, and perform various settings necessary for IP (Internet Protocol) communication. However, it is difficult to expect such knowledge about personal computers and the Internet from ordinary households, and the fact is that it is a hindrance to their spread. In view of this, a system has been proposed in which a communication function of a PHS or a mobile phone can be easily used. This uses a PC card configured as a general-purpose communication module so that communication is possible.

This enables communication with various remote terminal devices and facilitates highly scalable communication systems. Can be built.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes a communication terminal control module configured according to the present invention, and its functional configuration is shown in a block diagram. Reference numeral 1a denotes an interface, which is connected to a remote terminal device B such as a monitor camera B1, an infrared remote controller B2, and a security sensor B3 to exchange signals. Reference numeral 1b is application software for driving the remote terminal device B, and is stored in a semiconductor memory. This semiconductor memory is preferably of a write-once type, so that writing and rewriting are possible. Thus, arbitrary application software can be stored in correspondence with the type of remote terminal device B to be connected.

  Next, a communication platform configured by circuit function blocks as communication means includes Telnet software 1d, TCP / IP protocol software 1e, and PPP protocol software 1f so that communication on the Internet is possible. It can be used from the application software 1b via an API (Application Program Interface).

  As other elements that control the above communication processing, communication application software 1h that performs processing such as connection processing of PHS and cellular phone information communication network N1, wireless packet software 1i that generates packet signals, and L1 / L2 software Wear 1j, baseband converter 1k, and RF converter 1l are provided to enable communication with the outside.

  Reference numeral 1g denotes traffic management software, which manages the transmission frequency and data amount of the communication terminal control module 1. That is, the transmission frequency to the information communication network N2 to be described later is monitored together with the amount of data in an arbitrarily determined unit such as hourly, daily, weekly, monthly, etc. When exceeded, the traffic fuse works to forcibly prohibit outgoing calls and reduce the burden on the center server. The traffic management software 1g has a function for notifying a preset destination when a traffic fuse functions, a function for allowing a server administrator to cancel the function of the traffic fuse, and server management. It also has a function that enables the administrator to update the management setting value.

  In the communication terminal control module 1 of the present invention configured as described above, each functional element is controlled by a common CPU 1m, and application processing and communication control of a remote terminal device are performed. Therefore, a component configuration for achieving both functions The manufacturing cost can be reduced. Further, the communication terminal control module 1 configured as described above can be easily mounted on the remote terminal device B, and the monitor camera B1, the infrared remote control B2, and the security sensor B3 communicate directly with the information communication network N2 as shown in FIG. It becomes possible to do.

  FIG. 3 shows a communication system constructed by the remote terminal equipment B (B1, B2, B3) in which the communication terminal control module 1 described above is installed. In FIG. 3, reference numeral 2 denotes a mobile phone as a representative example. It is assumed that this is a physical information device that can transmit and receive data to and from an information communication network N1 constructed by a communication carrier. On the other hand, the information communication network N2 is also constructed by a telecommunications carrier. A center server S is interposed between the information communication networks N1 and N2, and the remote terminal device B and the mobile phone 2 are relayed by the center server S. Data communication between each other is made possible.

  The center server S is constructed by a virtual mobile service operator (MVNO: Mobile Virtual Network Operator), which is a so-called communication carrier that does not have a communication line facility, and is connected to the center server S. The information is limited to the communication line, and information from the remote terminal device B always passes through the center server S. The MVNO is a communication system having such characteristics. However, even in a state where a large number of remote terminal devices B are connected to the information communication network N2, it is assumed that transmission / reception with a small communication frequency and data amount is performed as in the present invention. If it does, it becomes a rational communication system.

  Then, by specifying and restricting the communication line between the center server S and the information communication network N2 as described above, the server administrator of the center server S and the communication carrier of the information communication network N2 Therefore, when the user installs the remote terminal device B, the line use contract can be simplified and the communication cost can be extremely low. That is, the application processing from the remote location of the remote terminal device B or the transmission of data from the remote terminal device B, which is the object of the present invention, has a small communication frequency and data amount, so that there are many uses for each unit of the communication line. Communication costs can be reduced.

  The center server S mainly stores command data for performing application processing on the remote terminal device B and exchanging information, and an instruction signal is transmitted via the information communication network N1 by a key operation of the mobile phone 2. When transmitted to the center server S, the command data is transmitted from the center server S to the selected remote terminal device B via the information communication network N2. When an instruction signal is transmitted by key operation of the cellular phone 2, the center server S interprets this ID number by transmitting the ID number for selecting a specific remote terminal device B, and specifies it securely. The remote terminal device B can be connected. In addition, when actively transmitting information like the security sensor B3, information that can specify the telephone number of the mobile phone 2 to be transmitted is set in the remote terminal device B in advance, and this information is transmitted together. Make the connection possible.

  Next, the flow of communication processing in the communication system configured as described above will be described with reference to FIG. In the case of the example shown in FIG. 3, for example, in order to check the state of an animal (pet) reared at home, the mobile phone 2 is connected to the center server S via the information communication network N1, and the key operation is performed. An instruction signal for requesting transmission of the image file is transmitted (ST1). The center server S that has received the instruction signal forms an e-mail including command data from the instruction signal (ST2), and the e-mail is transmitted from the center server S to the monitor camera B1 (ST3).

  When the monitor camera B1 receives the e-mail in the e-mail reception standby state (ST4) (ST5), the reception control is performed in the communication platform in the communication terminal control module 1, and then the application software 1b is selected, and the system The power supply is started and content analysis of the e-mail is started (ST6). The content of the e-mail is analyzed as described above, and based on this, image processing such as image recording by the monitor camera B1 and size adjustment of the recorded image is performed (ST7), and the image data is transmitted from the communication terminal control module 1 to the information communication network. It is transmitted to the center server S via N2 (ST8), and the monitor camera B1 is returned to an e-mail reception standby state.

  When the center server S receives the image data (ST9), the center server S is configured to be able to send the image data by e-mail (ST10), and information (URL) indicating the storage location of the image file is added to the message prompting reception of the image data. The added e-mail is transmitted to the mobile phone 2 (ST11), and the image file is stored in the storage means (ST12). When the mobile phone 2 receives this e-mail (ST13), the user accesses the center server S by the URL attached to the e-mail (ST14). When the center server S receives the image file transfer request from the mobile phone 2, the center server S transmits the image file via the information communication network N1 (ST15), and the mobile phone 2 that receives the image file displays the image on the display. Confirmation by the user becomes possible.

  When performing application processing of household appliances (air conditioners, lighting, video, etc.) in the home by the same operation procedure as described above, the communication terminal control module 1 is directly incorporated into these devices, or the communication terminal is connected to the infrared remote controller B1. It is also possible to incorporate the control module 1. In this case, in the same manner as described above, a desired home appliance is designated by key operation of the cellular phone 2, the application software 1b is selected, and an instruction signal for requesting a desired operation is transmitted from the cellular phone 2.

  In addition, in the security sensor B3 that detects the opening and closing of doors, windows, etc. in the absence home, by incorporating the communication terminal control module 1 of the present invention, when the doors, windows, etc. are opened by an intruder during absence, the security sensor B3 is activated and wirelessly connected to the information communication network N2, so that an alarm message can be transmitted to the mobile phone 2 of the user. In addition, by the same means, it is possible to prevent theft of a passenger car and to check the security with an in-vehicle monitoring camera. In addition, remote notifications such as automatic dispatch of emergency notifications of abnormal conditions of children and the elderly, confirmation of the current location of children and pets using GPS, confirmation of nursery rooms such as nurseries, and confirmation of the remaining number of products in vending machines A system for grasping can be easily constructed.

  In the communication system of the present invention constructed as described above, the communication terminal control module 1 receives the mail sent in response to the request from the mobile phone 2 so that the standby mode of the remote terminal device B becomes the operation mode. It is possible to obtain a power saving effect. Further, the destination of the information generated by the remote terminal device B is determined by analyzing the received mail, the destination of the information generated when the remote terminal device B is activated, and the remote terminal device The communication terminal control module 1 can set a password for accessing B.

  Further, the communication terminal control module 1 is provided with traffic management software 1g, monitors the transmission frequency and the data amount, and prohibits the transmission operation when the transmission frequency and the data amount reach a preset management setting value. Have a traffic fuse to work. As described above, the communication line of the information communication network N2 connected to the center server S is specified and restricted, but the frequency of transmission / reception between the mobile phone 2 and the remote terminal device B and its frequency This system is based on the assumption that the amount of data is small, and can accommodate a large number of users for each unit of the communication line and operate stably.

  However, if the user who installed the remote terminal device B is frequently used on the same communication line at the same time, such as unsteady usage, for example, frequently operating the monitor camera B1 to capture a large amount of image files, Trouble occurs in communication processing. The traffic management software 1g is intended to prevent such a problem in advance, and allows an allowable upper limit value of the transmission frequency and the data amount to be set as a management setting value, and based on this management setting value. Monitor (hourly, daily, weekly, monthly, etc.), and if the usage exceeds this management setting value, make the traffic fuse function to limit the extreme usage of the remote terminal device B. ing.

  In this case, when the traffic fuse functions for a specific remote terminal device B, the remote instruction from the mobile phone 2 to the remote terminal device B becomes impossible. In order to cope with such a state, the center server S is provided with a storage means for temporarily storing a specific remote terminal device B in which the traffic fuse functions, and when the remote terminal device B is accessed, the traffic fuse functions. A message having a meaning is sent to the mobile phone 2.

  Further, the server administrator of the center server S accesses the remote terminal device B in which the traffic fuse is functioning, and confirms that the traffic fuse is functioning by the release routine of the traffic management software 1g of the communication terminal control module 1. It can be canceled. Further, the server administrator of the center server S can access the remote terminal device B individually, and update the management set value by the update routine of the traffic management software 1g of the communication terminal control module 1, and can communicate information with the center server S. The management setting value can be changed based on the communication status with the network N1.

  FIG. 5 shows specific means for connecting different kinds of remote terminal devices B and performing application processing in the communication terminal control module 1 configured as described above. This figure specifically shows the storage state of the application software 1b of the communication terminal control module 1 shown in FIG. 1, and is composed of a reception / analysis processing unit 20 and a function processing unit 30, and this function processing unit 30 Includes a plurality of function processing units 41, 42, and 43 and I / O processing units 51, 52, and 53.

  The reception / analysis processing unit 20 receives an instruction from the mobile phone 2 owned by the user of this system at the center server S, analyzes the operation instruction information transmitted as a script to the communication terminal control module 1, The function processing unit 30 is instructed to perform the target operation. In response to an instruction from the reception / analysis processing unit 20, the function processing unit 30 executes specific processing by the function processing 1 to n of the function processing units 41, 42, and 43 according to the specified processing content, and receives the results. Transfer to the analysis processing unit 20. On the other hand, the I / O processing units 51, 52, and 53 perform specific operation control of the remote terminal device B controlled by the I / O processes 1 to m based on the I / O processes 1 to m.

  The function processes 1 to n and the I / O processes 1 to m are prepared for the number of service functions provided by the center server S. With this configuration, the manufacturer of the remote terminal device B that has been supplied with the communication terminal control module 1 can incorporate the communication terminal control module 1 into the remote terminal device B so that communication is possible. An instruction from the telephone 2 can be received. The specific operation of the remote terminal device B is executed in accordance with a script sent from the center server S, so that there are fewer restrictions on usage.

  The communication terminal control module 1 incorporates I / O processes 1 to m for controlling a remote terminal device B (camera, GPS module, sensor, etc.) into which the communication terminal control module 1 is incorporated. Are connected via an I / O connector, and the remote terminal device B connected to the I / O connector is managed by I / O page management.

  FIG. 6 shows an outline of resource management by I / O page management. Specifically, I / O pages 1 to m are configured by control registers called I / O pages, and the following management is performed. That is, the I / O page register is placed at the parallel interface address MA = 7, and the default value of the I / O page register is I / O page 0.

  The I / O page register can be controlled by the parallel interface of the I / O connector of the communication terminal control module 1. The I / O page register is virtually placed on the I / O page (I / O page Reg = 00000000). FIG. 7 shows the relationship between the I / O page register value and the I / O page value.

  The I / O page register is virtually placed on I / O page 0 (IP page register = 00000000). The relationship between the I / O page register value and the I / OP value is shown in FIG. The I / O page register can be changed by the parallel interface address signal (MA03 to 1) MA = 7 of the I / O connector. Since the address signal (MA03 to MA01) of the parallel interface of the I / O connector is controlled by the address MA = 7, the restrictions shown in FIG. 8 are attached.

  By the way, the present invention is also characterized in that it can be configured at a low cost. By adopting the modularized communication terminal control module 1, simplification, generalization and mass production, reduction of software development amount, software management are achieved. The center server S transmits a script for specifically instructing the operation to the terminal, and the received terminal executes the operation according to the script to control the operation of the remote terminal device. Since control can be performed from the server S side, it is possible to differentiate services that can be provided even if similar remote terminal devices are used.

  FIG. 9 shows an example of a specific configuration when the present invention is implemented in a security camera. A wireless IP communication network (N2) based on MVNO, a center server S connected to the wireless IP communication network, and a client A security camera type wireless IP packet terminal device (B1) installed at a remote location (such as a general home), and a mobile phone 2 owned by the user, a center server S, and a security camera type wireless IP packet terminal device (B1) Can communicate with each other and provide services.

  An operation instruction is sent from the mobile phone 2 to the security camera wireless IP terminal (B1) as a script via the center server S, and the contents of the script are processed. The processing result of the contents of the script is returned to the center server S, and the center server S processes the result into an image file format corresponding to the mobile phone 2 and outputs the result to the display of the mobile phone 2. Therefore, the present invention is characterized in that the mobile phone 2 operates as a client of the center server S.

  By the way, in a conventional security camera used as a terminal, the operation settings such as the number of pixels of the image receiving element (for example, VGA (640 × 480) / QVGA (320 × 240)) and the image compression rate are hardware such as a switch. Selected by the software, converted into an operation flag by software processing, and stored in a frame memory or the like. Therefore, the specific operation according to the operation instruction from the mobile phone 2 is determined by the security camera itself of the terminal and the processing result is transmitted to the mobile phone via the server. The camera operation cannot be changed.

  On the other hand, in the present invention, the number of pixels and the image compression rate can be specified as operation parameters from the mobile phone 2 via the center server S by a script. Furthermore, it is possible to perform script control to which a composite function, for example, a control function capable of turning on / off a lighting fixture based on day / night discrimination with respect to the operation of the monitoring camera is added.

  For example, the terminal processing n assigned to the communication terminal control module 1 as the content of script control is as follows: terminal processing 1: camera shooting, terminal processing 2: image compression, terminal processing 3: image transmission, terminal processing 4: lighting on, terminal Process 5: Set to turn off the light. In the above setting, when the surveillance camera is operated in the daytime, the terminal processing 1: camera shooting (specified size), terminal processing 2: image compression (specified compression ratio), terminal processing 3: image processing in the order of image transmission Exit. When the surveillance camera is operated at night, terminal processing 4: lighting, terminal processing 1: camera shooting (specified size), terminal processing 2: image compression (specified compression rate), terminal processing 3: image transmission, Terminal processing 5: The terminal processing is terminated in the order of lighting off.

  FIG. 10 shows a configuration example in which a remote controller and a GPS are mounted on a terminal serving as a remote terminal device. The I / O connector 101 of the communication terminal control module 1 is connected to the I / O page register 102 via the I / O page register 102. The GPS unit 104 is connected to the unit 103 and the I / O page 6.

  The serial output (STxD) of the I / O connector 101 is connected to the serial input terminal (RSRxD) of the GPS unit through the gate G1, and is connected to the serial input terminal (RSRxD) of the remote control unit 103 through the AND gate G3. ing. The serial output signal (GTSxD) of the GPA unit 104 is connected to the OR gate G5 via the AND gate G2, and the serial output signal (RSTxD) of the remote control unit 103 is connected to the OR gate G5 via the AND gate G4. The output of the OR gate G5 is connected to the serial input terminal (SRxD) of the I / O connector 101.

  When the output I / OP1 of the I / O page register 102 becomes active (ON), the serial signal connected to the gate G3 and the gate G4 becomes valid, and when the I / OP6 becomes active (ON), the gate G1 and the gate G2 are connected. The connected serial signal becomes valid. With this configuration, when I / OP1 is selected, the serial output signal (RTSxD) of the remote control unit 103 is input to the I / O connector 102, and when I / OP6 is selected, the serial of the GPS unit 104 is selected. An output signal (GTSxD) is input to the I / O connector 101, and the serial output signal (RSTxD) of the remote control unit 103 and the serial output signal (GSTXD) of the GPS unit 104 can be controlled without conflict.

  FIG. 11 shows an example of control of the remote control unit 103 and the GPS unit 104 in the above-described configuration. The script content is analyzed by the reception / analysis processing unit 20, and the process n1 is started by an instruction “obtain current position information”. , “GPS command set” processing is performed. In the “GPS command set” process, after the I / O page register 102 is set to 6 in the I / O process m1, a reception result transmission command is transmitted to the GPS unit 104 as a serial signal.

  Subsequently, as “GPS reception data reading” processing, in the I / O processing m2, the I / O page register is set to 6 and then data transmitted from the GPS unit as a serial signal is received. Similarly, the content of the script is analyzed by the reception / analysis processing unit 20. In “remote control pattern acquisition”, processing is performed by the processing n 2 and the I / O processing m 3. Processing is performed by m4.

  As shown in the above example, I / O device management by the I / O page register 102 is simple and can effectively use limited I / O resources while avoiding I / O contention. Further, in a terminal configuration in which there are few I / O devices and no contention occurs, it is not necessary to mount the I / O page register 102. Therefore, it is possible to simply configure the terminal and reduce the hardware load. The function processing is not changed by not mounting the / O page register 102.
