By simply specifying the number, the contents of the sign can be changed immediately to match the local situation.

In addition, this invention is not limited only to the said embodiment.
In the above-described embodiment, an example in which the center server 31 is accessed from the PC 11 through the Internet 2 has been described. In addition, each mobile terminal can be used by a mobile terminal (such as a mobile phone or a PDA) having an Internet connection function. By preparing Web contents in accordance with the screen and the access form in the center server 31, the same functions as in the above embodiment can be realized in the mobile form.
In the above embodiment, the center server 31 and the mobile phone network 6 are connected via the IP-VPN network 5 and the INS line 4. However, if the confidentiality can be maintained and the mobile phone network 6 can be connected, another network can be used. The IP-VPN network 5 and the INS line 4 are not essential. If a predetermined number of LAN ports can be prepared in the communication module 83, the hub 84 and the like are not essential when there is no additional LAN connection device.
Moreover, in the said embodiment, although the indicator 89, the web camera 88, etc. were illustrated as some local apparatus connected to the communication unit 81, for example, a microphone & speaker, a speed sensor, an approach alarm device (hose switch) ), Information input / output devices such as thermometers, anemometers, weigh scales, traffic counters, GPS receivers, etc. can be connected to the communication unit 81. Can be output.
Furthermore, in the above-described embodiment, an example in which the communication unit 81, the indicator 89, and the Web camera 88 are separate hardware has been described for the local device 8. However, these devices may be integrated and further subdivided. May be used.
In the above embodiment, the number 80 is exemplified as the port for communicating with the Web camera 88, but the present invention is not limited to this port, and other ports may be used.

Next, a modified example (another embodiment) of the above embodiment will be described with reference to FIGS. In the case of the embodiment shown in FIG. 1, the local device 8 has the communication module 83 for connecting to the mobile phone network 6 as an essential component. When the display is performed, the center server 31 needs to dial up each local device 8 and establish a session with the mobile phone network 6, which increases communication costs.
Therefore, in the following modification, an example in which the communication cost is reduced when installing a plurality of local devices 8 will be described. In addition, about the structure same as the said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

As shown in FIG. 13, the LED-labeled wireless remote control system of this modification has a local device (parent device) 8a and a local device (slave device) 8b as local devices.
The local device (parent device) 8 a includes a wireless LAN access point 70 and a memory 80.

  The wireless LAN access point 70 is connected to one LAN port of the hub 84 via a LAN cable 86. The wireless LAN access point 70 includes an antenna 71 and performs wireless communication in conformity with IEEE 802.1X. Examples of IEEE802.1X include IEEE802.11a, IEEE802.11b, and IEEE802.11g.

When establishing a PPP session (connection) between the mobile phone network 6 and the communication module 83, the wireless LAN access point 70 establishes a wireless LAN between the wireless LAN client 74 of the local device (slave device) 8b and itself. And exchange of information with the center server 31 is relayed.
By using an omnidirectional antenna for the antenna 71, the wireless LAN access point 70 can be connected to a local device (slave unit) 8b by, for example, IEEE802.11b, for example, a radius of several hundred meters in the field with good visibility. Wireless communication of about 1 km is possible. Further, by using a directional antenna as the antenna 71, the wireless LAN access point 70 can perform wireless communication of several hundreds m to several Km in a linear distance.

A local IP address is set in the LAN / RS485C85 of the local device (parent device) 8a.
The memory 80 is provided in the communication module 83. As shown in FIG. 14, an address conversion table 80a in which a local IP address on the communication unit side and an IP address on the wireless side are associated with each other is set in the memory 80.

  The communication module 83 converts the destination address of the IP packet received from the center server 31 with reference to the address conversion table 80a of the memory 80, and transmits the IP packet to a local device. In the communication module 83, for example, the wireless side address 172.10.1.100 is converted to the communication unit side IP address 192.168.1.x.

  On the other hand, in the memory of the center server 31, as shown in FIG. 15, there is a device management table 36 in which connection IP addresses, ports, local device information, etc., which are IP addresses on the wireless side, are registered for each communication module telephone number. It is remembered. In the field of local device information, the name of the device connected to each port and the device number are written correspondingly.

  The local device (slave device) 8 b includes a communication unit 73 including a wireless LAN client 74 and LAN / RS485C85, and an indicator 89 connected to the communication unit 73 via a serial cable 87. The wireless LAN client 74 has an antenna 72. A local IP address is set in the LAN / RS485C85. In this example, only the indicator 89 is connected to the communication unit 73, but a device such as the Web camera 88 may be connected as in the example of FIG.

The wireless LAN client 74 constructs a wireless LAN with another local device (parent device) 8 a having a wireless LAN access point 70 that has established a PPP session (connection) with the mobile phone network 6, and the wireless LAN access point 70. And exchanges information with the center server 31.
By constructing a wireless LAN between the local device (parent device) 8a and the local device (slave device) 8b in this way, the number of ports as hardware is not limited compared to the case of hub connection. Many local devices (slave devices) 8b can be connected to the local device (master device) 8a.

  In the LED sign wireless remote control system of this modification, for example, when accessing the center server 31 through the authentication process from the PC 11 and displaying “running caution” on a desired indicator 89, for example, the indicator 89 of the local device 8b, When the route list screen shown in FIG. 10 and the route map A shown in FIG. 11 are followed and a desired No is selected and operated, a local information screen 94 of the selected No. indicator is displayed as shown in FIG.

  Here, the CH. For example, if “012” is input as the number, “traveling caution” is displayed as the content of the indication. If the indication is correct, the operator selects and operates the transmission button 99.

Then, the CPU of the center server 31 reads the telephone number of the communication module to which the selected No. indicator is connected from the memory, and dials up to the mobile phone network 6.
Thereby, a PPP session (connection) is established between the mobile phone network 6 and the communication unit 81.

When the connection is established, the CPU of the center server 31 sends the CH. In order to control the LED indication by number, a TCP socket using a private port: XXXXXX is read out by referring to the device management table 36 of the memory, reading the destination connection IP address and port, etc., and making the instructed information an IP packet The data is sent to the communication unit 81 by communication.
When receiving the IP packet, the communication unit 81 refers to the address conversion table 80a of the memory 80, converts the IP address of the received packet into an address on the communication unit side, and sends the IP packet for LED indication control to the LAN / RS485C85. send.

The LAN / RS485C85 wirelessly communicates the received IP packet to the local device (slave device) 8b through the wireless LAN access point 70.
In the local device (slave device) 8b, when the wireless LAN client 74 receives the IP packet, it passes it to the LAN / RS485C85.
When the delivered IP packet is an IP packet having an IP address destined for itself, the LAN / RS485C85 extracts an LED indication command from the IP packet and serially outputs it to the indicator 89.

  In the indicator 89, when the LED indication command is received by the communication I / F 21, the control unit 22 causes the CH. Using the number as a key, the corresponding marking data is read from the memory 23 and output to the marking memory 24, and is sequentially output from the marking memory 24 to the LED marking unit 26 through the LED marking output unit 25. The LED marking unit 26 displays “ "Running caution" is displayed.

  As described above, according to the LED sign wireless remote control system of this modification, at least one of the local devices is installed in order to perform the indication suitable for the site by installing the plurality of local devices 8 at desired positions on the road. The base is a local device (master unit) 8a equipped with a wireless LAN access point 70, and a plurality of local devices (slave units) 8b equipped with a wireless LAN client 74 connected to the master unit 8a via a wireless LAN are arranged in the field. As a result, only one base unit 8a establishes a connection with the mobile phone network 6, so that information can be wirelessly transmitted to a number of slave units 8b under the base unit 8a, and connections for the number of local devices are established. Communication costs can be greatly reduced.

  Although an example in which the local device (master unit) 8a and the local device (slave unit) 8b are connected by a wireless LAN is the best mode, if a wireless connection environment that maintains confidentiality can be established, another wireless network can be used. For example, WiMAX (Worldwide Interoperability Microwave Access) or the like may be used. For example, Bluetooth may be used although the communication distance does not reach the wireless LAN.
