  As shown in FIG. 5, the container information 114 is a data table in which identification information of the wireless device 120 and container detailed information 501 are associated with each other.

  The container detailed information 501 is information indicating characteristics such as the shape (type) and installation location of the container 130 to which each wireless device 120 is attached.

In the traveling route 260, identification information of the wireless device 120 corresponding to the order (first to fifth in FIG. 7) is stored.

  Each of the base station 110 and the wireless device 120 stores the traveling route information 124 in the storage unit 113 or the storage unit 123.

  Next, the cyclic data 300 transmitted from the base station 110, transmitted / received one after another between the wireless devices 120, and returned to the base station 110 will be described.

  As shown in FIG. 8, the cyclic data 300 includes a header area 310, a data area 320, and a footer area 330.

  In the header area 310, identification information of the wireless device 120 or the base station 110 that has transmitted the cyclic data 300 is stored.

  In the footer area 330, the traveling route identification information 250 designated in advance by the administrator or the like by the control unit 111 of the base station 110 is stored.

  In the data area 320, waste amount data acquired from the sensor 140 by the control unit 121 of each wireless device 120 is stored. The data area 320 is divided into divided areas 321 to 325. Each wireless device 120 stores waste amount data in order from the divided area 321 to the divided area 325 (the divided area 321, the divided area 322,..., The divided area 325) according to the order indicated by the circulation route 260.

  When the control unit 111 of the base station 110 creates the cyclic data 300, “00” indicating the initial value is stored in the divided areas 321 to 325 of the cyclic data 300.

Next, a procedure for circulating the cyclic data 300 between the base station and the radios 120-1 to 120-5 will be described with reference to FIG.
Here, in order to facilitate understanding, it is assumed that “001” is designated as the traveling route identification information. In this case, according to the cyclic route information 124 shown in FIG. 7, the cyclic route is the identification information 001 → 010 → 011 → 100 → 101, that is, the radios 120-1 → 120-2 → 120-3 → 120-4. → 120-5.

  The base station 110 sets the identification information “111” of the base station 110 in the header area 310 of the cyclic data 300, and sets the cyclic route identification information “001” in the footer area 330. The base station 110 transmits the generated cyclic data (arrow 401).

  Radio 120-1 receives cyclic data 300 transmitted from base station 110, determines from the information in header area 310 and the information in footer area 330 that it is cyclic data 300 to be received by itself, and Capture.

  The wireless device 120-1 stores the waste amount data acquired from the sensor 140-1 in the divided region 321 allocated to itself in the data region 320 of the circulating data 300, and the identification number of the wireless device 120-1 in the header region 310. After overwriting, the cyclic data 300 is transmitted (arrow 402).

  Radio 120-2 receives cyclic data 300 transmitted from radio 120-1, and determines that it is cyclic data 300 that it should receive from the information in header area 310 and the information in footer area 330. Capture this.

  The wireless device 120-2 stores the waste amount data acquired from the sensor 140-2 in the divided region 322 of the data region 320 of the cyclic data 300 received, and overwrites the identification information “110” of the own device in the header region 310. Thereafter, the cyclic data 300 is transmitted.

  Similarly, while the waste amount data is stored by the control unit 121 of each wireless device 120, the cyclic data 300 is transmitted and received between the wireless devices 120-2 to 120-5 in the order indicated by the arrows 403 to 405. . Then, the cyclic data 300 is transmitted from the wireless device 120-5, and finally the base station 110 receives it (arrow 406).

  Next, details of the operation when each wireless device 120 receives the cyclic data 300 will be described.

  First, when receiving the cyclic data 300 via the communication unit 122, the control unit 121 of each wireless device 120 reads the identification information stored in the header area 310.

  Next, the control unit 121 reads the tour route identification information 250 stored in the footer area 330.

  Next, the control unit 121 refers to the tour route information 124 stored in the storage unit 123 and determines the tour route 260 corresponding to the tour route identification information 250. And the control part 121 discriminate | determines the order of the said radio | wireless machine 120 based on the said cyclic | annular route 260, and discriminate | determines the radio | wireless machine 120 of the transmission source based on the order which the said cyclic | annular route 260 shows.

  The control unit 121 compares the identification information of the wireless device 120 that is the transmission source according to the order indicated by the cyclic route 260 and the identification information stored in the header area 310, and if they match, The waste amount data acquired from the sensor 140 is stored in the data area 320. Then, the control unit 121 stores its own identification information in the header area 310 of the cyclic data 300 and transmits this to the outside via the communication unit 122.

  On the other hand, the identification information of the wireless device 120 that is the transmission source according to the order indicated by the cyclic route 260 is compared with the identification information stored in the header area 310. Since 300 is not transmitted from the wireless device 120 in the order indicated by the traveling route 260, the control unit 121 does not store the waste amount data.

Next, the overall operation of the waste amount information providing system 100 having the above configuration will be described.
As shown in FIG. 9, the order indicated by cyclic route 260 starts in the direction of arrow 401, and cyclic data 300 is transmitted and received in the order of arrows 402 to 405, and returns to base station 110 in the direction of arrow 406 (cyclic route). It is assumed that the administrator sets the identification information 250 to “001”.

  When collecting information on the amount of waste put in each container 130, the control unit 111 of the base station 110 transmits, for example, the cyclic data 300 illustrated in FIG. 10A to the outside via the communication unit 112.

  As shown in FIG. 10A, “000”, which is identification information of the base station 110, is stored in the header area 310, data indicating an initial value is stored in the data area 320, and cyclic route identification information 250 is stored in the footer area 330. "001" is stored.

  The control unit 121 of the wireless device 120 that has received the cyclic data 300 via the communication unit 122 operates according to the cyclic data processing shown in FIG.

  The control unit 121 of the wireless device 120-1 that has received the cyclic data 300 reads the identification information stored in the header area 310 (step S601).

  Next, the control unit 121 reads the traveling route identification information 250 stored in the footer area 330 (step S602).

  Next, the control unit 121 determines the tour route 260 corresponding to the tour route identification information 250 from the tour route information 124 stored in the storage unit 123 (step S603).

  Next, the control unit 121 determines the order of the wireless device 120 based on the determined cyclic route 260 and determines the wireless device 120 that is the transmission source according to the order indicated by the cyclic route 260. Then, the control unit 121 compares the identification information of the wireless device 120 that is the transmission source according to the order indicated by the cyclic route 260 with the identification information stored in the header area 310 (step S604).

  If the identification information of the wireless device 120 that is the transmission source according to the order indicated by the cyclic route 260 matches the identification information stored in the header area 310 (step S604: YES), the control unit 121. Acquires the waste amount data from the sensor 140-1 and stores it in the divided area 231 (step S605).

  For example, if the waste amount data acquired by the control unit 121 from the sensor 140-1 is “11” indicating fullness, the waste amount data “11” is stored in the divided area 321 as illustrated in FIG. .

  Next, the control unit 121 stores its own identification information in the header area 310 (step S606). For example, as illustrated in FIG. 10C, the control unit 121 stores the identification number “001” of the own device in the header area 310.

  Next, the control unit 121 transmits the cyclic data 300 to the outside (step S607), and the cyclic data processing ends.

  If the traveling data 300 received by the wireless device 120-1 is not sent from the transmission source according to the order indicated by the traveling route 260 (step S604: NO), the traveling data processing ends.

  For example, the case where the cyclic data 300 is transmitted from the wireless device 120-5 corresponds to the arrow 450 shown in FIG. In this case, identification information “101” of the wireless device 120-5 is stored in the header area 310 of the cyclic data 300. Since the traveling route identification information 250 is “001”, the order of the wireless device 120-1 indicated by the traveling route 260 is the first in the traveling route information 124 shown in FIG. Therefore, since the transmission source according to the order indicated by the cyclic route 260 is the base station 110, the cyclic data 300 is not transmitted from the base station 110, so even if the cyclic data 300 is received from the radio unit 120-5, it is wireless. Machine 120-1 does not store waste volume data.

  When the other wireless device 120 receives the cyclic data 300 transmitted from the wireless device 120-1 according to the cyclic data processing, the wireless device 120 that has received the data operates according to the cyclic data processing.

  For example, if the traveling data 300 transmitted from the wireless device 120-1 is received by the wireless device 120-2, the control unit 121 of the wireless device 120-2 operates according to the traveling data processing. In this case, since the control unit 121 of the radio device 120-2 is the cyclic data 300 received from the transmission source (the radio device 120-1) based on the order indicated by the cyclic route 260, the waste amount data is stored in the divided area 322 of the cyclic data 300. Is stored (step S605).

  The control unit 121 of the wireless device 120-2 rewrites the header area 310 in which the identification information of the wireless device 120-1 is stored, and stores the identification information “010” of the own device (step S606). And the control part 121 of the radio | wireless machine 120-2 transmits the said cyclic data 300 to the exterior (step S607).

  Similarly, when the control unit 121 of each wireless device 120 receives the cyclic data 300 via the communication unit 122, the control unit 121 operates according to the cyclic data processing. The cyclic data 300 is stored in the data area 320 while waste amount data is stored. The wireless devices 120 are transmitted and received according to the order indicated by the traveling route 260. Then, as indicated by an arrow 406 illustrated in FIG. 9, the base station 110 receives the cyclic data 300 transmitted by the wireless device 120-5, and the base station 110 acquires waste amount data in each container 130.

  Note that the cyclic data 300 received by the base station 110 has, for example, a data configuration as shown in FIG. The identification information of the wireless device 120-5 is stored in the header area 310 of the cyclic data 300 in FIG. 10D, and the waste amount data is stored in the divided areas 321 to 325.

  Next, the operation of the base station 110 that has received the cyclic data 300 will be described.

  When receiving the cyclic data 300 through the communication unit 112, the control unit 111 of the base station 110 operates according to the cyclic data processing of the base station shown in FIG.

  First, the control unit 111 of the base station 110 reads the identification information stored in the header area 310 (step S701).

  Next, the control unit 111 reads the traveling route identification information 250 stored in the footer area 330 (step S702).

  Next, the control unit 111 refers to the cyclic route information 124 stored in the storage unit 113 and determines the cyclic route 260 corresponding to the cyclic route identification information 250 (step S703).

  Next, the control unit 111 reads out the identification information of the last wireless device 120 in the order indicated by the determined cyclic route 260 and compares the identification information with the identification information stored in the header area 310. Then, the control unit 111 determines whether or not the cyclic data 300 is transmitted from the last wireless device 120 in the order indicated by the cyclic route 260 (step S704).

  When it is determined that the cyclic data 300 is data transmitted according to the order indicated by the cyclic route 260 (step S704: YES), the control unit 111 determines that n = 1 and m = the radio device 120 indicated by the cyclic route 260. N and m are set so as to be the number of (step S705).

  Next, the control unit 111 reads the identification information of the wireless device 120 that stores the waste amount data in the nth divided area (first is first) with reference to the cyclic route information 124 (step S706).

  Next, the control unit 111 refers to the container information 114 (eg, FIG. 5), and reads the container information corresponding to the identification information of the wireless device 120 that stores the waste amount data in the nth divided region (step) S707). Then, the control unit 111 reads out the waste amount data stored in the n-th divided area from the cyclic data 300, and refers to the waste amount data output information 115 (for example, FIG. 6) to refer to the waste amount data. The amount of waste corresponding to is read (step S708). Then, the control unit 111 associates the container information with the amount of waste and stores it in the output information 116 (step S709).

  Next, the controller 111 determines whether or not n = m (step S710). If n = m is not satisfied (step S710: NO), n ← n + 1 is set (step S711). Follows the operation of step S706.

  If n = m (step S710: YES), the cyclic data processing of the base station ends.

  When the cyclic data processing of the base station is completed, the control unit 111 causes the output unit 117 to output the output information 116 in which the container information and the amount of waste are associated as shown in FIG. To do.

  In this way, the waste processor or manager can know the amount of waste in each container 130 by outputting waste amount data based on the cyclic data 300 from the base station 110.

  As described above, by outputting the amount of waste for each container 130 from the base station 110, the waste processor, for example, does not go to the collection of waste in the container 130 where the amount of waste is a certain amount or less. The collection operation can be performed efficiently, for example, only the container 130 that needs to be collected is directed to collection.

(Other embodiments)
The waste amount information collecting system 100 can be variously modified in addition to the above embodiments. Hereinafter, another embodiment in which when a problem occurs in the wireless device 120, the wireless device 120 in which the problem has occurred can be known will be described.

  As shown in FIG. 14, in the cyclic data processing in the other embodiments, a step (step S801) of transmitting received data is added after the cyclic data transmission (step S607) in the cyclic data processing of the first embodiment. Yes.

  The control unit 121 of the wireless device 120 that has transmitted the received data according to the cyclic data processing shown in FIG. 14 (step S801) ends the cyclic data processing and enters a standby state. When receiving data is received in the standby state, the control unit 121 cancels the standby state.

  When the reception data transmitted from the wireless device 120 that is the transmission destination in the order indicated by the cyclic route 260 is not received in the standby state, it is assumed that a failure has occurred in the wireless device 120 of the transmission destination. In this case, the control unit 121 of the wireless device 120 in the standby state creates error notification cyclic data 380 and notifies the base station 110 that a problem has occurred. The received data includes the identification information of the wireless device 120 that has transmitted the received data, and the control unit 121 of the wireless device 120 that has received the received data determines the transmission source based on the identification information.

  A specific example of the above operation will be described. Here, it is assumed that wireless device 120-2 operates in accordance with the cyclic data processing shown in FIG. 14 and transmits received data (step S801). The identification information of the traveling route 260 and each wireless device 120 is the same as that of the first embodiment.

  First, the wireless device 120-2 enters a standby state, and the control unit 121 operates according to a standby process illustrated in FIG.

  When the control unit 121 of the wireless device 120-2 receives reception data from the wireless device 120-3 via the communication unit 122 after the start of the standby processing (step S501: YES), the standby processing ends.

  When the received data cannot be received (step S502: NO), the time from the start of the standby process is measured by a timer (not shown) included in the control unit 121, and a predetermined time has not elapsed since the start (step S502: NO), it returns to step S501 again, and the control part 121 confirms the presence or absence of reception data reception.

  If the predetermined time has passed without receiving the received data (step S501: NO) (step S502: YES), the control unit 121 creates the error notification cyclic data 380 (step S503).

  The error notification cyclic data 380 includes the cyclic route identification information 250 stored in the footer area 330 of the cyclic data 300 transmitted to the outside according to the cyclic data processing, in the order indicated by the cyclic route 260 indicated by the cyclic route identification information 250. The data is rewritten to the cyclic route identification information 250 corresponding to the cyclic route 260 in the opposite direction.

  For example, if the cyclic data 300 transmitted by the radio device 120-2 has the data configuration shown in FIG. 15A, the control unit 121 of the radio device 120-2 uses the error notification cyclic data 380 shown in FIG. create. As shown in FIG. 15B, in the footer area 330 of the error notification cyclic data 380, “010” which is the cyclic route identification information 250 in the reverse direction to the order indicated by the cyclic route 260 “001” of the cyclic data 300. Is stored.

  For example, the order indicated by the cyclic route identification information 250 stored in the cyclic data 300 is the order of arrows 401 to 406 as shown in FIG. In this case, the cyclic route identification information 250 stored in the error notification cyclic data 380 becomes the cyclic route identification information 250 in the order indicated by the arrows 901 to 906.

  The cyclic route identification information 250 stored in the footer area 330 of the error notification cyclic data 380 is predetermined by the administrator. The storage unit 123 stores the cyclic data 300 transmitted by the cyclic data processing.

  Next, the control unit 121 transmits the error notification cyclic data 380 to the outside (step S504), and the standby process ends.

  When the other wireless device 120 receives the error notification cyclic data 380, it operates according to the cyclic data processing shown in FIG.

  If there is no problem with the wireless device 120 on the way, the base station 110 receives the error notification cyclic data 380 and operates according to the cyclic data processing of the base station shown in FIG.

  For example, the case where the base station 110 receives the error notification cyclic data 380 illustrated in FIG. 15C will be described as an example.

  Since “00” indicating the initial value is stored in the divided areas 323 to 325 of the error notification cyclic data 380 illustrated in FIG. 15C, the control unit 111 of the base station 110 performs, for example, as illustrated in FIG. Output information 116 is created.

  Then, the administrator can know the amount of waste in each container 130 by outputting the output information 116 from the base station 110. Further, the administrator refers to the container 130 in which the initial value of the output information 116 is stored, and knows the radio device 120 having a defect based on the order indicated by the tour route 260 set by the administrator. it can.

  As described above, according to other embodiments, when an abnormality occurs in the wireless device 120, the administrator of the base station 110 can know this. Note that when the standby state reaches a predetermined time, the control unit 121 transmits the cyclic data 300 again, and when the reception data cannot be received even if the cyclic data 300 is transmitted a plurality of times, an error notification cycle is performed. Data 380 may be created.

  As another modification, for example, the number of wireless devices 120 may be a number other than five.

  In addition, although the result measured by the sensor 140 is represented by 2-bit data as the waste amount data, the present invention is not limited to this, and the waste amount data may be known in more detail by representing multiple bits. .

  As described above, the waste amount information providing system according to the present invention collects waste amount data in a plurality of containers and provides it to a waste processor or the like. Since the waste amount information providing system according to the present invention transmits and receives cyclic data between wireless devices installed at a short distance, the base station inquires each wireless device far from the base station and collects the waste amount data. Can be implemented with less power. For this reason, the power source of the radio device can be energy generated from the solar battery. The waste amount information providing system according to the present invention is characterized in that it can be easily installed and equipment can be made inexpensive because only a radio device and a sensor are attached to the container.
