FIG. 5 is a schematic diagram illustrating a configuration example of the energization control unit 322 illustrated in FIG. 3. FIG. 6 is a schematic diagram for explaining the operation of the water level abnormality detection device 3 shown in FIG.

  As shown in FIG. 2, the water level abnormality detection device 3 includes a cylindrical housing 31, a detection unit 32 provided in the housing 31, a weight 33 fixed to the circumferential portion of the housing 31, A nylon thread 34 having one end fixed to one end surface of the housing 31 and a weight 35 fixed to the other end of the thread 34 are provided. The casing 31 is made of a material adjusted to a density that allows radio waves to pass through and floats on water, can withstand pressure standards equivalent to JIS 10k, and is provided inside the clean water W without entering the inside. The structure which comprises the part 32 grade | etc., Has an airtight structure which is not exposed outside. That is, since the water level abnormality detection device 3 is thrown into the purified water W, the casing 31 is harmless, the detector 32 is not submerged, and has a size that can be poured from the opening of the reservoir 2. And it must be recoverable.

  As shown in FIG. 3, the detection unit 32 includes a power source 321, an energization control unit 322, a storage unit 323, and an information communication unit 324. The power source 321 is constituted by a lithium ion battery, for example, and supplies power for operating the information communication unit 324. The energization control unit 322 controls power supply from the power source 321 to the information communication unit 324. Specifically, the energization control unit 322 is configured by a mechanical switching element that switches supply / stop of electric power according to a change in the direction of action of gravity as shown in FIGS. 4 and 5, and the level of the purified water W is When it is below the predetermined value, the power of the power source 321 is supplied to the information communication unit 324.

  Note that the switching element shown in FIG. 4 includes a weight 322a, a switching unit 322b, and a rod-shaped member 322c that connects the weight 322a to the switching unit 322b in a swingable manner. The switching element shown in FIG. 4 is in an off state when the weight 322a is at the position P1, but is turned on when the weight 322a reaches the position P2 due to the influence of gravity or the like, and outputs a control signal from the output terminal 322d. 5 includes a columnar member 322e, a fixed member 322f fixed to the columnar member 322e, and a moving member 322g inserted through the columnar member 322e so as to be movable. The switching element shown in FIG. 5 is in an off state when the fixed member 322f and the moving member 322g are not in contact with each other, but is turned on when the fixed member 322f and the moving member 322g are in contact with each other, and outputs a control signal.

  The storage unit 323 is configured by a non-volatile storage device such as a ROM, and stores information related to an e-mail address to which an e-mail is transmitted when a water level abnormality occurs. The information communication unit 324 is configured by an information processing device such as a microcomputer, and transmits an e-mail to an e-mail address stored in the storage unit 323 when a water level abnormality occurs.

  In the water level abnormality detection device 3 having such a configuration, when the water level of the purified water W is equal to or higher than a predetermined value, the end surface of the housing 31 is pulled by the weight 35 as shown in FIG. No. 31 is in an upright state (upright state) in which the end surface is parallel to the water surface. The predetermined value of the water level can be determined as appropriate by adjusting the length of the yarn 34. On the other hand, as shown in FIG. 6B, when the water level of the purified water W becomes less than a predetermined value, the weight 35 comes into contact with the bottom surface G of the reservoir 2 and the thread 34 is loosened, so that the circumference of the casing 31 is increased. Due to the weight 33 fixed to the surface, the casing 31 falls over with its end surface perpendicular to the water surface.

Thereby, the water level abnormality of the distributing reservoir 2 can be detected accurately.

(Water level abnormality detection method)
Next, a water level abnormality detection method by the water level abnormality detection system according to this embodiment configured as described above will be described. FIG. 7 is an explanatory diagram for explaining the water level abnormality detection method. FIG. 7 shows respective time-lapse states in the reservoir 2, the management terminal 6, the mail server 5, and the alarm receiver 4, and shows processing operations of the abnormality detection device 3 in those time-lapse states.

  As shown in FIG. 7, the water level abnormality detection method according to this embodiment includes a water level abnormality detection device 3 that detects a state of water level abnormality reduction in the distribution reservoirs 2 in various places, an alarm reception device 4 as a management contract terminal, It is executed between the mail server 5 including the incoming mail server 5b and the outgoing mail server 5a and the management terminal 6 capable of controlling the water level abnormality detection device 3.

  That is, while the water level in the distribution reservoir 2 is in a normal state, the management terminal 6 sends an e-mail to be transmitted from the water level abnormality detection device 3 to each distribution reservoir 2 when the water level of the distribution reservoir 2 is abnormally lowered. An e-mail including information data such as a destination and an emergency contact person is stored in the mail server 5. Specifically, when a water level abnormality occurs in the distribution reservoir 2, for each distribution reservoir 2, a command “Which management contractor's alarm receiver 4 is notified of an email” and “emergency contact person in charge” E-mail including “information” is stored in the mail server 5. In FIG. 7, an example of the table of the combination of the water reservoir 2 in which the water level abnormal fall which becomes this instruction | command and the email receiving apparatus 4 with an alarm is shown. In this table, when a water level abnormal drop occurs in the distribution reservoir 2a, an e-mail is transmitted to the alarm receiver 4c. When a water level abnormal drop occurs in the reservoir 2b, the alarm receivers 4a, 4b Stores information for sending an e-mail. Then, based on this table information, the management terminal 6 sends an e-mail information including a command “Which management contractor's alarm receiver 4 is notified of the e-mail” and “emergency contact person information”. Generate data.

  Thereafter, when the water level in any reservoir 2 (for example, reservoir 2a) drops abnormally, the water level abnormality detection device 3 (for example, water level abnormality detection device 3a) shifts from the normal position to the overturned state, and the power is turned on. (Step ST1). Here, it is assumed that the information communication unit 324 is activated in order to suppress the frequent transmission of an e-mail due to the occurrence of chattering in which the energization control unit 322 is frequently switched on / off due to vibration or the like. For a predetermined time sufficiently longer than the chattering period, specifically 30 seconds to 5 minutes, preferably 1 minute to 2 minutes. And after this predetermined time passes, the information communication part 324 in the water level abnormality detection apparatus 3 starts (step ST2). Thereby, the water level abnormality detection device 3a becomes in a communicable state.

  Immediately after activation, the water level abnormality detection device 3a transmits an e-mail to the transmission destination stored in the storage unit 323 if the activation is the first time, and to the transmission destination previously transmitted if the activation is a plurality of times (step) ST3). The electronic data included in the e-mail includes at least information data related to the reservoir 2. Furthermore, as this electronic data, the location name data of the reservoir 2 where the water level abnormality has occurred, that is, the location name data of the reservoir 2a where the water level abnormality detection device 3a is installed, and the latitude and longitude data of this location Identification name data such as the name of the person in charge of emergency contact and telephone number data, data of the time when the abnormality occurred and the date and time of occurrence of the abnormality that occurred in the past, and e-mail in this time and the past Necessary data is appropriately selected and adopted from the transmission destination and the data of the number of transmissions. In addition, when the method of executing the e-mail transmission operation at regular time intervals is adopted, it is possible to recognize the time during which the water level of the distribution reservoir 2a is abnormally lowered depending on the number of e-mail transmissions.

  Further, the water level abnormality detection device 3a receives the electronic mail stored in the mail server 5 by the management terminal 6 (step ST4). That is, the water level abnormality detection device 3a receives electronic data including instruction data (instruction information) as control data for executing a predetermined operation, and stores at least the instruction data in the storage unit 323. The instruction data includes, for example, instruction information for an operation of transmitting an e-mail as reservoir information from the water level abnormality detection device 3a to the alarm reception device 4c to the water level abnormality detection device 3a. It should be noted that, depending on the setting in the water level abnormality detection device 3, it is possible to set so that the e-mail is deleted before and after the e-mail is received or transmitted.

  Thereafter, the water level abnormality detection device 3 receives the above-described electronic data as a new e-mail transmission destination included in the instruction information, and a predetermined alarm reception that is the e-mail transmission destination included in the instruction information. In the device 4, in this embodiment, for example, the e-mail address is transmitted to the alarm receiving device 4c having “E@mail.jp” to notify the water level abnormality (step ST5). The instruction information may include other control data for controlling the water level abnormality detection device 3. The worker who uses the alarm receiving device 4c responds according to the content of the received e-mail, and performs the water level abnormality recovery work on the reservoir 2a.

  When the water level is restored in the reservoir 2a by the water level abnormality recovery work for the reservoir 2a by the worker, the water level abnormality detector 3a is turned upside down, and the water level anomaly detector 3a is turned off at this stage. (Step ST6). Thereby, the water level abnormality detection operation of the water level abnormality detection device 3a becomes a standby state and returns to the initial state (step ST7). Thus, the water level abnormality detection method according to this embodiment is executed.

  According to the embodiment of the present invention described above, the water level abnormality detection device 3 falls from the normal position to the overturned state, and the water level is maintained after the power is turned on for a predetermined time or more after the power is turned on. By making the abnormality detection device 3 communicable and sending an e-mail containing information necessary for the occurrence of a water level abnormality in a predetermined reservoir 2 to a predetermined alarm receiving device 4, It is the occupant of the management contract terminal that detects the water level abnormality in the reservoir 2 at an early stage and accurately while preventing chattering without being affected by the wobble of the water surface. The worker can immediately recognize it.

  In addition, according to this embodiment, since the water level abnormality detection device 3 employs the battery driving method, the water level abnormality detection device 3 can be turned on only when the water level is lowered. Even in places where it is difficult to provide a normal power source, such as the above, the water level abnormality detection device 3 can be used for a long period of time.

  In addition, in waterworks facilities, etc., when the electrical equipment and mechanical equipment are under construction for repairs, etc., it may be assumed that the facility monitoring level will be lowered, such as when the original function is stopped. The Even in this case, the operator can recognize without overlooking the drop in the water level of the distribution reservoir 2, which is one of the most important facilities in the waterworks.
