Description

  According to the present invention, a plurality of wireless communication devices constructs a tree from a management device, and data to be transmitted / received by each wireless communication device is relayed by a wireless communication device on the higher side than the own device, and the management device The present invention relates to a wireless communication system that transmits and receives data and a power supply monitoring control system using the same.

  Japanese Patent Application Laid-Open No. 2004-133867 shows a typical conventional technique using the wireless communication system as described above for meter reading of electricity, gas, water, or the like. In this conventional technology, the meter reading data is collected and integrated into the higher-level terminal station (wireless communication device), and further transferred to the higher-level side. Compared to the case where the management device polls each terminal station individually. Data can be collected in a short time.

On the other hand, in Patent Document 2, the setting contents are automatically taken over when the terminal station is exchanged by temporarily downloading the data to the setting tool from the terminal station connected to the telephone line and setting it to the newly installed terminal station. An automatic meter reading system that can be used has been proposed.
JP 2000-187793 A Japanese Patent Laid-Open No. 7-162539

  Therefore, by applying the method of Patent Document 2 to Patent Document 1, it is possible to easily exchange the terminal station by the wireless communication device. However, in the case of failure replacement, data may not be downloaded. In addition, in the case of new installation or expansion, it is necessary for an operator to measure surrounding radio wave conditions and to set a communication path such as a hanging wireless communication device. Specifically, the measurement result of the radio wave condition is separately communicated to the management device side (sales office) by telephone or the like, and the route table (map) of the network managed by the management device side (sales office) is referred. However, among the terminal stations with good radio wave conditions, a terminal station with a relatively small number of hanging terminal stations is selected, and that terminal station is set as a call destination. In other words, the network is reconstructed under the leadership of the management apparatus side (sales office).

  The objective of this invention is providing the radio | wireless communications system which can perform an optimal setting easily and rapidly, and the electric power feeding monitoring control system using the same.

The wireless communication system according to the present invention includes a management device that manages a network, a plurality of wireless communication devices having wireless communication means arranged in a tree shape, and data to be transmitted / received by each wireless communication device is higher than the own device. In the wireless communication system that is relayed by the wireless communication means of the wireless communication device on the side and transmitted / received to / from the management device, each wireless communication device includes an activation unit that generates a trigger for incorporation into the network, In response to a trigger from the activation means, the wireless communication means is activated, a radio wave situation due to communication between adjacent radio communication apparatuses is determined, and the radio communication means is sent to a radio communication apparatus having the best radio wave situation. by call, and a control means for the wireless communication device to transmit relay the registration request to the network to the management device, at least a portion of the radio communication The control means causes the wireless communication means to make a call to an adjacent wireless communication apparatus and sequentially relay and transmit the hierarchy of the tree, and to call a non-adjacent wireless communication apparatus. is allowed and a second operation mode for relay transmission transcends hierarchy of the tree, in a wireless communication apparatus that has received the registration request, Rukoto be relay-transmitted the registration request in the second operation mode It is characterized by.

  According to the above configuration, in a wireless communication system in which a network is configured by arranging a large number of wireless communication devices from a management device in a tree shape, the wireless communication devices cannot take over data by new installation, addition, or failure replacement In response to the update of the case, when transmitting a registration request to the management device via a nearby wireless communication device, there is provided an activation means for shifting to the registration mode and a control means for controlling the registration operation, and the activation means Is operated, the control unit activates the wireless communication unit to perform the reception operation, and measures the radio wave condition due to communication between adjacent wireless communication devices. From the measurement result, the control means causes the wireless communication means to call the best wireless communication apparatus, and relays a registration request to the network from the wireless communication apparatus to the management apparatus. If the registration request is valid, the management apparatus that has received the registration request returns a registration response to the wireless communication apparatus that has issued the request through the reverse path or a newly designated path. In this way, the control means that has received the registration response formally determines the wireless communication device on which the device itself hangs, communicates with the management device via the wireless communication device, and completes the incorporation into the network.

  Therefore, the operator can automatically set the network via the network without measuring the surrounding radio wave condition and setting the communication path of the hanging wireless communication device or the like one by one. Further, it is possible to hang an optimum wireless communication device such as a wireless communication device with the highest electric field strength level or a wireless communication device with few transmission errors. Thus, the optimum setting can be easily and quickly performed.

In addition , when sequentially transmitting data to be transmitted / received from a plurality of wireless communication devices to the management device as described above, at least some wireless communication devices sequentially follow the hierarchy of the tree, that is, higher-order than the own device. The normal operation data has two paths: a first operation mode that passes through all of the wireless communication devices and a second operation mode that transcends the hierarchy, that is, does not pass through some wireless communication devices. In the first operation mode, the wireless communication devices in each layer are sequentially traced, and the data is appropriately merged / divided to be transmitted at a preferable timing. On the other hand, urgent data is transmitted to the second operation mode. In this operation mode, the wireless communication devices of some layers are skipped, and only the data is immediately transmitted without being merged or divided. In a wireless communication system having two such operation modes, the registration request is jump-transmitted in the second operation mode.

  Therefore, the newly established, added or updated wireless communication device can be quickly incorporated into the network.

  Furthermore, in the wireless communication system of the present invention, in the first operation mode, the wireless communication means transmits the data generated by the own device from the terminal side when the own device acts as a relay station and transfers data. It is characterized in that it is transferred in combination with the transferred data.

  According to the above configuration, at the time of transfer, the wireless communication device serving as a relay station transfers the sensing data generated by itself in combination with the sensing data transmitted from the terminal (lower level) side. Thus, although the data length becomes longer as the management device (upper side) becomes, the traffic can be greatly reduced as compared with the case where each wireless communication device individually transmits data to the management device.

  In the wireless communication system of the present invention, when the wireless communication means transfers data as a relay station in the first operation mode, the wireless communication means starts from the data transferred from the management device side. It is characterized in that the data to be received by itself is divided and transferred.

  According to the above configuration, at the time of transfer, the wireless communication device serving as a relay station divides control data from the management device to its own device from control data sent from the management device (higher level) side. By doing so, the data length becomes longer as it becomes the management device (upper level) side, but the traffic can be greatly reduced compared to the case where the management device transmits data individually to each wireless communication device. .

  Furthermore, the wireless communication system of the present invention further includes a setting tool that sucks data from the wireless communication device to be exchanged and sets the newly installed wireless communication device.

  According to the above configuration, data such as the hanging destination of the own device can be taken up from the removed wireless communication device and automatically set in the newly installed wireless communication device, so that the update work is efficient. Can be done.

  Preferably, the data transmitted from the terminal (lower) side to the management device (upper) side is sensing data collected by each wireless communication device, and is transmitted from the management device (upper) side to the terminal (lower) side. The data is control data for each wireless communication device.

  Further preferably, the wireless communication means performs communication in a PHS (Personal Handyphone System) transceiver mode.

  The power supply monitoring and control system according to the present invention includes, in the above-described wireless communication system, a watt-hour meter that acquires sensing data and a load switch that performs open / close control in response to the control data. It is characterized by that.

  According to the above configuration, the total amount of power used for each time zone and the power outage associated with moving in and out can be remotely monitored at the power company sales office without the workers going directly to the contracted home or office. Can be done. As a result, it is possible to adopt a detailed fee system, or to quickly charge or power outage, and to improve customer service in the power company.

  As described above, the wireless communication system of the present invention is a wireless communication system in which a network is formed by arranging a large number of wireless communication devices from a management device in a tree shape. When relaying a nearby wireless communication device and transmitting a registration request to the network to the management device, measure the radio wave condition due to communication between adjacent wireless communication devices and issue the best wireless communication device from the measurement result. Call and relay transmit the registration request.

  Therefore, the operator can automatically perform the setting via the network without measuring the surrounding radio wave conditions and setting the communication path of the hanging wireless communication device or the like one by one. Further, it is possible to hang an optimum wireless communication device such as a wireless communication device with the highest electric field strength level or a wireless communication device with few transmission errors. Thus, the optimum setting can be easily and quickly performed.

  In addition, as described above, the power supply monitoring and control system of the present invention includes a watt-hour meter that acquires the sensing data and a load that performs opening and closing control in response to the control data in the wireless communication device. It consists of a switch.

  Therefore, it is possible to collect power consumption by time of day and to perform power outages due to moving in and out remotely at power company sales offices, etc. without going directly to contract homes or offices. it can. As a result, it is possible to adopt a detailed fee system, or to quickly charge or power outage, and to improve customer service in the power company.

  FIG. 1 is a block diagram showing an overall configuration of a power supply monitoring control system according to an embodiment of the present invention. The power supply monitoring and control system includes a server device 1 installed at a power company sales office and the like, and one or a plurality of gateways GWa and GWb connected to the server device 1 via a communication line 2 such as an in-house optical fiber network. , GWc,... (Generally indicated by reference numeral GW) and unit power meters T1-1, T1-2, T1-3,. The unit power meters T1-1, T1-2, T1-3,...; T2-1, T2-2,. T3-2,... (Generally referred to as reference symbol T below).

  Each unit wattmeter T is similar to the structure previously proposed by the applicant of the present invention in Japanese Patent Laid-Open No. 2006-292442 and Japanese Patent Laid-Open No. 2006-170787, and is configured as shown in FIG. . That is, the load switch 3, the watt-hour meter 4, and the wireless communication device 5 are arranged from the terminal block 6 side to which each distribution line in the house is connected. The watt-hour meter 4 reads the accumulated power amount every predetermined period, for example, every 30 minutes, and the meter-reading data as sensing data is set to a timing preset by each unit watt meter T by the wireless communication device 5. , Transmitted to the gateway GW to which the own device belongs, and is collected and input to the server device 1. On the other hand, control data for performing opening / closing of the load switch 3 or backup meter reading for retransmitting non-delivery meter reading data is transmitted from the server device 1 via the gateway GW as needed. Sent to

  The server device 1 holds a route table as shown in FIG. 1 showing how the unit wattmeters T are arranged. As described above, the server device 1 periodically receives data from the built-in wireless communication devices 5. In addition, the meter reading data of the watt-hour meter 4 can be acquired, and the load switch 3 can be controlled via each wireless communication device 5 as necessary. In addition, a power outage associated with moving in and out can be performed remotely at a power company sales office or the like, without the operator having to go directly to the contracted home or office. As a result, it is possible to adopt a detailed fee structure, to promptly perform billing and power failure, and to improve customer service in the power company.

  In each unit power meter T, in the prior art of Patent Document 1, a type-wired communication device that draws a communication signal line from a utility pole or the like is used for the portion of the wireless communication device 5. Then, using a device that performs wireless communication in a PHS (Personal Handyphone System) transceiver mode, a communication operation is performed as follows. In the PHS transceiver mode, when the line of sight is visible, communication is possible within a radius of 150 to 200 m, and each wireless communication device 5 communicates not only with the adjacent wireless communication device but also directly with the gateway GW in some cases. Is also possible.

  FIG. 3 is a block diagram illustrating a configuration example of the wireless communication device 5. The wireless communication apparatus 5 includes the PHS wireless device 11 serving as wireless communication means, a wireless communication control unit 12 and a timer 13 that control the communication, a memory 14 that stores parameters necessary for communication, An input operation unit 15 that can set a part of the contents of the memory 14, a memory 16 that stores a communication status, an external interface 17 that is connected to an external setting tool to be described later, and a watt hour meter 4 An interface 21 for receiving meter-reading data, an interface 22 for transmitting control data to the load switch 3, an in-machine communication control unit 23 for controlling communication with the watt-hour meter 4 and the load switch 3, The memory 24 for storing the meter-reading data as backup data and the transmission / reception of the meter-reading data and control data from the wireless device 11 are performed as described later. - a data processing unit 25 for processing the split, and includes a working memory 26 which is used during the data processing.

  On the other hand, FIG. 4 is a block diagram illustrating a configuration example of the server apparatus 1 that is a management apparatus. The server device 1 collects meter reading data from the input operation unit 51 and the watt hour meter 4 of each unit watt meter T serving as a terminal station, and also controls a unit control unit 52 that controls the load switch 3, The database 53 storing the load control status and the contract No. of each unit power meter T. A network management unit 56 and a database 54 for managing data relating to each unit power meter T, such as the telephone number # 01 of the own machine and the telephone number # 11 of the call destination, and the communication line 2 are connected to each other from the gateway GW. An interface 57 that communicates with the unit power meter T is provided.

  The gateway GW replaces the in-machine communication control unit 23, the interfaces 21, 22 and the data memory 24 for controlling communication with the watt hour meter 4 and the load switch 3 in the configuration of the wireless communication device 5 shown in FIG. The communication control unit configured to communicate with the communication line 2 and an interface are configured.

  In the power supply monitoring and control system configured as described above, each wireless communication device 5 is set from the input operation unit 15 and has the telephone number # 01 of the own device in the memory 14, and the meter reading at normal times. It has a telephone number # 11 of a higher party (calling destination) to which data is transferred, and another telephone number # 12 used for emergency control or relay transmission of a registration request and response described later. The telephone number # 11 is the telephone number of the unit power meter adjacent to the own device according to the hierarchy of the route table, and the other telephone number # 12 is at least a part of the unit power meter to the own device exceeding the hierarchy. It is the telephone number of the unit power meter that is not directly adjacent.

  Specifically, in the example of FIG. 1, unit power meters T1-1, T1-2, T1-3, T1-4, T1-5, which are the lowest terminal stations; T1-11, T1-12 (generic name) In this case, the telephone number # 01 is a-300, a-310, a-320, a-330, a-340; b-300, b-310, respectively. , Registered in advance from the input operation unit 15. The telephone numbers # 11 include unit power meters T2-2, T2-4, T2-6, T2-8, T2-10; a-120, a-140, a-160, a-180, a-200; b-120, b-140 are registered in advance.

  On the other hand, the telephone number # 12 used at the time of emergency or relay transmission of the registration request and response includes the telephone numbers of unit power meters that are two or more higher stations, for example, unit power meters T1-11. , T1-12, telephone numbers b-30 and b-80 of T4-11 and T3-12 are registered in advance from the input operation unit 15. Even if the telephone number # 12 is not set in advance, the telephone number and the hierarchy of the surrounding unit wattmeter are detected by monitoring the electric field strength, and the telephone of the higher unit wattmeter than the own unit is detected. You may make it search and set a number autonomously.

  In the wireless communication device 5 configured as described above, first, in the normal state which is the first operation mode, the wireless communication control unit 12 receives the meter reading data from the lower side received by the wireless device 11 as the data processing unit 25. To enter. On the other hand, the meter processing data received from the in-machine communication control unit 23 via the interface 21 and stored in the memory 24 is transmitted to the data processing unit 25 in advance by the meter reading data. It is read out every period, for example, every 30 minutes. Then, the data processing unit 25 uses the working memory 26 to perform processing for merging the input data, and creates new meter reading data.

  In the new meter-reading data, the radio communication control unit 12 is added with its own telephone number stored in the telephone number # 01 of the memory 14, for example, b-80 in the unit power meter T3-12. Thereafter, at the timing specified by the timer 13, the radio number from the radio unit 11 is stored in the telephone number # 11 and the telephone number of the higher-level radio communication apparatus adjacent to the own unit, for example, the unit power meter T3-12 The unit power meter T4-11 b-30 is called to transmit. In the server device 1, the unit controller 52 receives the meter reading data from the interface 57, divides the merged data, and stores it in the database 53 for each customer.

  Thus, when the own device becomes a relay station and transfers data, the wireless communication control unit 12 merges the meter reading data from the lower side with the meter reading data from the lower side and transfers it to the upper side. Thus, the data length becomes longer as the server device 1 (upper side) becomes, but the traffic can be greatly reduced as compared with the case where each wireless communication device individually transmits data to the server device 1. . If the own device is a terminal station, there is no meter reading data transferred, so that the wireless device 11 does not receive the data, and the data processing unit 25 does not merge the meter reading data. The meter reading data from is sent as it is.

  On the other hand, in the control data from the server device 1, all the telephone numbers of the wireless communication devices to be routed in accordance with the route table are described in the header portion, and the wireless communication control unit 12 The control data arrived at its own device is analyzed, and the call is transferred to the telephone number of the wireless communication apparatus to be transmitted next, so that the transfer is performed. For example, the control data from the server device 1 relayed by the unit power meter T4-11 is, for example, T3-in accordance with the data of the unit power meters T3-11 and T3-12 in the next layer at an arbitrary timing. 12 will be transferred. At this time, the control data received by the wireless device 11 is input from the wireless communication control unit 12 to the data processing unit 25, and the control data addressed to the own device is divided using the working memory 26. In response to the control data, the in-flight communication control unit 23 performs the opening / closing control of the load switch 3 via the interface 22, or reads out the meter reading data that has not been reached from the memory 24, and The transmitter 11 is made to perform backup transmission.

  In this way, by dividing the control data to be received by the own device from the control data from the upper side and transferring it to the lower side, the data length becomes longer toward the server device 1 (upper side). Compared with the case where the device 1 transmits data to each wireless communication device individually, the traffic can be greatly reduced. If the own device is a terminal station, since there is no control data to be transferred, transmission by the wireless device 11 is not performed, and control data is not divided by the data processing unit 25. In FIG. 1, in the tree on the gateway GWa side, an arrow having a thickness corresponding to the amount of data is shown in order to easily show the merging of meter reading data and the division of control data.

  The data stored in the memory 24 is data of accumulated electric power measured by the watt-hour meter 4 at 0 and 30 minutes per hour as indicated by reference numeral 24a in FIG. Information may be stored together, and the storage capacity is selected to be a capacity capable of accumulating meter reading data for, for example, 40 days. The database 53 on the server device 1 side stores meter reading data for each customer, load control status, power failure status, and the like for a longer period.

  On the other hand, when the data to be transmitted urgently such as the result of the switching control from the load switch 3 or the backup meter reading data is generated, the wireless communication control unit 12 sets the emergency state as the second operation mode. Become. Then, the wireless communication control unit 12 creates transmission data by adding the telephone number of the own device stored in the telephone number # 01 to the data, and creates the transmission data in the wireless device 11 in the memory 14. The telephone number of the jump-destination wireless communication apparatus that is not adjacent to the own device stored as 12, for example, the unit power meter T1-12 makes a call with b-80 of the unit power meter T3-12 to perform transmission. . At this time, in the PHS transceiver mode, only 1: 1 communication can be performed. Therefore, when the jump destination unit power meter T3-12 is already busy, the wireless communication control unit 12 is assumed to end communication. After waiting for a while, the emergency data is transmitted. That is, each wireless communication device 5 is configured to finish one communication within 15 seconds, and when the jump transmission cannot be performed, the retry transmission is performed three times at intervals of 5 seconds, so that the jump transmission is performed. Is realized.

  The wireless communication control unit 12 of the unit power meter T3-12 that has received the data by the wireless device 11 immediately issues the data to the gateway GWb stored as the telephone number # 12 in the memory 14 of the wireless device 11 in its own device. Call and transfer. Thus, the emergency data from the lower side can be quickly transmitted with the minimum number of relays.

  Further, for example, emergency control data such as a power failure (open / close control of the load switch 3) accompanying the move-in / out and a request for transmission of backup meter reading data from the server device 1 is sent from the unit controller 52 to the interface 57. And is transmitted via the gateway GWb to the telephone number b-80 of the unit power meter T3-12 stored in the control data. The communication control unit 12 of the wireless communication device 5 of the unit power meter T3-12 that has received this call similarly makes a call to the telephone number b-310 of the unit power meter T1-12 stored in the control data. Perform the transfer. The in-machine communication control unit 23 of the unit wattmeter T1-12 that has received the control data performs the open / close control of the load switch 3 via the interface 22, or stores the meter reading data that has not been reached into the memory 24. The wireless device 11 performs backup transmission. In this way, emergency data from the upper side can be quickly transmitted with the minimum number of relays.

  In this way, in the normal state of the first operation mode, regular meter reading data collection and control data distribution can be performed regularly and in a short time, while the second operation mode is in an emergency or abnormal state. In some cases, data can be transmitted quickly. Further, the memory 14 of each wireless communication device 5 stores only the telephone number # 11 of the adjacent higher-order wireless communication device and the telephone number # 12 of the higher-order wireless communication device that is the jump destination. The route table may not be provided, the storage capacity can be reduced, and the route can be easily changed.

  Further, in the memory 14, hierarchical information indicating to which hierarchy in the route table the own device belongs is registered from the input operation unit 15, and the wireless communication control unit 12 transmits the hierarchical information at the time of transmission. The wireless communication control unit 12 of the other wireless communication device receives the hierarchical information, and receives the telephone number of the wireless communication device of the highest hierarchy received, Register to the telephone number # 12. In the example of FIG. 1, the gateways GWa, GWb, GWc,... Are located in the highest first hierarchy, and unit power meters T5-1, T5-2; T5-11, T5-12 are Located in the second hierarchy, similarly, unit power meters T4-1 to T4-4; T4-11 and T4-12 are located in the next third hierarchy, and unit power meters T3-1 to T3-5. T3-11, T3-12 are further located in the next fourth layer, unit power meters T2-1 to T2-10; T2-11 to T2-14 are further located in the next fifth layer, Unit power meters T1-1 to T1-5; T1-11 and T1-12 are further located in the next sixth layer.

  Therefore, for example, in the above description, in the terminal station power meter T1-11, although the telephone number b-30 of the unit power meter T4-11 is registered in the telephone number # 12, the radio wave environment is improved. For example, when communication with the gateway GWb becomes possible, the telephone number of the gateway GWb is updated. On the other hand, if it becomes impossible to receive the transmission signal from the unit power meter T4-11 due to the deterioration of the radio wave environment, the transmission signal from the unit power meter T3-11 one level below can be received and received. The telephone number b-70 is registered.

  Here, as shown by reference numeral 16a in FIG. 3, the memory 16 that stores the communication status stores the reception result of the signal transmitted from each wireless communication device by the wireless device 11, and is stored in the same hierarchy. When a plurality of transmission signals from the wireless communication apparatus are received, the station having the highest average value of the field strength level (for example, 30 dBμV or more) is selected. Alternatively, a station with a low BER may be selected, or they may be used in combination. In addition, since jump transmission is required to be reliably transferred, even if there is only one station whose electric field strength level is lower than a predetermined level, it is not selected, and a radio in the lower layer is not selected. The communication device is selected as the jump destination. Further, the jump destination selected by each wireless communication device is transmitted to the server device 1 once in a predetermined cycle, for example, once a day, and the same wireless communication device is relayed for control data from the server device 1 side. It is desirable that jump transmission is performed. In particular, when the server device 1 transmits a command to the target unit power meter, such as the backup meter reading data or the load switch 3 control result, and the execution result is required, it is the same for upstream and downstream. By using the route, the reliability can be improved (there is a high possibility that a response will be returned).

  By configuring in this way, when performing jump transmission in the case of an emergency or abnormality, transmission can be performed toward a wireless communication device in the range that can be reached at the maximum, and the number of relay stages can be minimized. The data can be transmitted in the shortest time. In the present embodiment, only one jump destination telephone number is stored in the telephone number # 12, but a telephone call from a wireless communication apparatus having the next highest average value and hierarchical level of the electric field strength level. The number may be stored together, and when the first telephone number fails to jump transmission a predetermined number of times, a call may be made to the next wireless communication device.

  In the power supply monitoring and control system configured as described above, it should be noted that in the present invention, when a new unit wattmeter T is installed in the tree-like network, the operation is performed from the input operation unit 15 as an activation unit. Is performed, the input operation unit 15 gives a trigger to the wireless communication control unit 12 as a control means, and in response to this, the wireless communication control unit 12 activates the wireless device 11 and makes an adjacent wireless communication A radio wave condition by communication between communication apparatuses is determined, and the radio unit 11 is called to the radio communication apparatus having the best radio wave condition, and the wireless communication apparatus 5 registers the network apparatus with the server apparatus 1. To send a request.

  Such a new unit wattmeter T is installed by a new installation, expansion or replacement. Among the exchanges, in a normal update operation, a dedicated setting tool is used as described later, the data of the wireless communication device to be removed is sucked up, and the wireless communication device of the unit wattmeter T newly installed Therefore, the determination of the radio wave condition as described above may not be performed. On the other hand, in the above-described exchange, when the data cannot be taken over due to the fault exchange, and in the case of new establishment or addition, the determination of the radio wave condition as described above is performed.

  FIG. 5 is a diagram for explaining an operation of incorporating a new unit power meter T into the network after performing such a radio wave condition determination. First, various settings are made from the setting tool 60 to the memory 14 of a newly installed unit power meter (T1-12 in the example of FIG. 5). The memory 14 may store data such as a unit watt meter manufacturer ID, model ID, machine number, and telephone number # 01 of the own machine, and may store a customer contract number and the like as appropriate. . The manufacturer ID, model ID, machine number, and other data may be stored in advance by the manufacturer, and the setting from the setting tool 60 may be performed at an actual installation location, or at a sales office or the like. It may be performed in advance.

  When the unit power meter T1-12 having been set is installed and a start operation is performed from the input operation unit 15 or the setting tool 60, a trigger is input to the wireless communication control unit 12 as described above. In response to this, the wireless communication control unit 12 activates the wireless device 11 and creates an electric field strength table as indicated by reference numeral 16a in FIG. 3 from the reception result. When the monitoring of the surrounding radio wave condition is completed for a predetermined period, the wireless communication control unit 12 jumps the telephone number of the wireless communication device having the highest electric field strength (b-80 of T3-12 in the example of FIG. 5) to the jump. After registering to the telephone number # 12 used for transmission, at least the contract No. Then, a registration request including data such as the telephone number # 01 of the own device, the manufacturer ID of the unit power meter, the model ID, and the device number is created, and the wireless device 11 issues the registration request to the wireless communication device registered in the telephone number # 12. The call is transmitted from the gateway GWb to the server device 1.

  Upon receiving the registration request, the network management unit 56 of the server device 1 performs registration processing such as creating the route table including the new unit power meter T1-12, and updates the contents of the database 54. Then, a registration response is returned to the unit power meter T1-12 through a route according to the created route table. In that case, in the example of FIG. 5, the unit power meter to be relayed is changed from T3-12 to T4-11. That is, in FIG. 1, the registration request is initially jump-transmitted through a solid line route, but in the network reconstructed by the server device 1, a virtual line route is designated and incorporation into the network is completed. . Thereafter, 30-minute meter reading data and the like are transmitted using this route.

  On the other hand, in the server device 1, the contractor information input in advance from the input operation unit 51 into the database 54, the information sent from the actual installation operator by telephone or the like, and the information received from the gateway GWb Are matched by the network management unit 56, and the contract No. If there is a mistake in the installed model or the like, the worker is notified as appropriate.

  Moreover, the example of FIG. 6 is a figure for demonstrating the installation operation | movement to the network of the new unit power meter T in the case of normal replacement | exchange. In this case, since the data from the unit power meter to be removed can be taken up and re-registered as described above, first, the unit power meter to be newly installed (T1 in the example of FIG. -12), the contract No. In addition, data such as own phone number # 01 and call destination phone numbers # 11 and # 12 are copied, and other settings are made. When the unit power meter T1-12 that has been set is installed and a start operation is performed from the input operation unit 15 or the setting tool 60, a trigger is input to the wireless communication control unit 12 as described above. In response, the wireless communication control unit 12 starts operation, calls the telephone number # 12 (b-80 of T3-12 in the example of FIG. 6) of the memory 14 copied from the removal machine, and jumps the registration request. Send.

  The network management unit 56 of the server apparatus 1 that has received the registration request is a route that has been used before, so the route is not reconstructed, and the registration processing of the ID of the new unit power meter T1-12, etc. The contents of the database 54 are updated, and a registration response is returned to the unit power meter T1-12 through a path opposite to the transmission path. The subsequent steps are the same as those in FIG.

  In this way, when the new unit wattmeter T is incorporated into the network, when the trigger is given, the wireless communication control unit 12 activates the wireless device 11 and determines the radio wave condition from the communication result between the adjacent wireless communication devices 5. Then, the wireless device 11 is called by the wireless communication device (unit power meter T3-12 in the examples of FIGS. 5 and 6) having the best radio wave condition, and the management device ( In the example of FIGS. 5 and 6, the server apparatus 1) relays the registration request to the network and accepts the registration request. If the registration request is valid, the server apparatus 1 takes the reverse path, Alternatively, a registration response is returned to the unit power meter T3-12 that issued the request through a newly designated route, and the incorporation into the network is completed. In a wireless communication system in which a network is arranged from 1 to a tree, an operator can measure the surrounding radio wave conditions and set up a network without setting a communication path such as a hanging unit power meter. Can be set automatically. Further, it is possible to hang an optimum wireless communication device such as a wireless communication device with the highest electric field strength level or a wireless communication device with few transmission errors. Thus, the optimum setting can be easily and quickly performed. Furthermore, meter reading data can be transmitted promptly.

  In addition, as described above, a registration request and a registration response are jump-transmitted, so that a newly installed, added, or updated wireless communication device can be quickly incorporated into the network.

  Furthermore, the update tool can be updated efficiently by using the setting tool 60 that sucks data such as the hanging destination of the own device from the removed wireless communication device and automatically sets the data to the newly installed wireless communication device. Can be done.

  In the above-described embodiment, an example in which the management device includes the server device 1 and the gateway GW is shown. This is an example of a management device, and may be a management device including a plurality of server devices, a management device that does not use the gateway GW, or the like. The management device that accepts the registration request may be the gateway GW. Furthermore, although PHS has been exemplified as the wireless communication method between the unit power meters T, other wireless communication methods may be employed, or a wired communication method may be employed.
