摘要： PROBLEM TO BE SOLVED: To improve a communication success rate even at a condition that received power becomes low by controlling the maxim number of times of retransmission of data when the initial transmission from a slave machine to a master machine is failed. SOLUTION: When a carrier detection means 41a detects a start message from a master machine to a slave machine 40, a return means 41b returns a response message to the master machine. A setting operation part 48 sets whether the return means 41b transmits data that a gas meter 20 measures once by the response message or consecutively transmits them three times. Namely, a setting operation part 48 is controlled at a site in accordance with received power level from the slave machine 40 to the master machine. When received power is low, it is considered that a communication success rate is deteriorated. Thus, data are set to consecutive three times transmission when the measured value of received power, which is measured at the time of site execution, is less than a prescribed value. When received power exceeds the prescribed value, data are set so that they are transmitted only once.

摘要： PROBLEM TO BE SOLVED: To solve a problem of ensuring a communication path between a center device and a meter even when a fault takes place in a prescribed channel and no communication is available in a wireless automatic metering system where the ratio of the number of wireless master set to the number of wireless slave sets is selected to be 1:N. SOLUTION: The wireless master set communicates with the wireless slave sets by the specified low power wireless communication and communicates with a center unit 6 via a PHS base station 5 through a PHS channel. Thus, even when the master set A is going to communicate with its upper-stream side unit but the communication is hindered because of occurrence of a fault in a prescribed communication channel, the master set A can employ a wireless channel to reserve an available communication path by bypassing the faulty communication path.

摘要： PROBLEM TO BE SOLVED: To provide a radio meter reading system capable of improving a communication success rate even under a condition in which received power is small. SOLUTION: Master units 30 exchange data with a center 10 through public lines 50. A slave unit 40 is connected to a gas meter 20 and exchanges data with the units 30 by a radio signal. The unit 40 is deployed so that it can communicate with the plurality of master units 30, and the center 10 selects which master unit 30 is to communicate with the unit 40. When the selected master unit 30 fails in communication with the unit 40, another master unit 30 is selected to communicate with the unit 40.

摘要： PROBLEM TO BE SOLVED: To efficiently conduct routing for a slave device and a master device, in a fixed type radio system. SOLUTION: A field is divided into multiple virtual blocks. The virtual block is divided into a plurality of areas. The broadcast communication is performed at the same time in a plurality of areas relatively at the same position, for collecting routing basic data. However, no broadcast communication is performed, if no target child device is within a communicable range. The required and sufficient data required for routing to a single slave device is provided, only by the simultaneous broadcast communication from relatively the same position area for an area within the block.

摘要： PROBLEM TO BE SOLVED: To smoothly plan station placing of a master set with an objective mark by giving an attribute corresponding to the intensity of the second signal to each building based on the second signal received by the first transmitter/ receiver, and preparing an attribute map given attributes concerning plural buildings. SOLUTION: A slave set 11 receiving the first signal 12 prepares the second signal 13 having contents corresponding to the first signal 12 to transmit this to a master set 10. At the time of receiving the second signal 13, the master set 10 prepares a signal including information corresponding to received electric field intensity and transmits this signal to a host computer 16, which reads electric field intensity information with respect to each slave set 11 from a signal received from the master set 10 and gives an attribute corresponding to this electric field intensity to the corresponding slave set 11. Continually, electric field intensity attribute is given to data on each building. Thus, an attribute map obtained by adding colors and patterns corresponding to the electric field intensity attribute to each building is provided as a printed matters by a printer 21.

摘要： PROBLEM TO BE SOLVED: To simplify the application of a device to be managed and reduce its price by making the communication of a satisfactory response possible without lowering a security level. SOLUTION: The remote monitoring system is composed of a virtual leased line 1, a plurality of devices 3 to be managed connected therewith via a LAN 2 and a control center 5 connected with the virtual leased line 1 via a LAN 4. The virtual leased line 1 is composed of routers 11 and 12. The router 11 encrypts data, identification information and destination information sent from a communication terminal 32, prepares a tunneling packet by adding the destination information of the router 12 thereto and sends it onto the Internet 10. The router 12 receives the tunneling packet, decrypts the encrypted data, the encrypted identification information and the encrypted destination information contained in the tunneling packet and transmits the data and the identification information to the control center 5 based upon the destination information. The control center 5 pairs and collects the data and the identification information from each of the devices 3 to be managed. COPYRIGHT: (C)2004,JPO
