A configuration divided into terminals can also be adopted.

  The remote monitoring device 200 is disposed at a remote location away from the water treatment device 100, and serves as a data management center that continuously monitors and manages a plurality of water treatment devices including the water treatment device 100. It has a function. That is, the communication terminal 160 of each water treatment device 100 is independently connected to the server 210 of the remote monitoring device 200 via the communication line 170. Such intensive water quality management in the remote monitoring device 200 is particularly effective for centrally monitoring the processing information of each water treatment device that is widely used, such as a home water treatment device. The remote monitoring device 200 here corresponds to the “remote monitoring device” in the present invention.

In addition, the “cleaning contractor” referred to here is typically the water treatment apparatus 100 based on a cleaning request commissioned indirectly from a maintenance manager commissioned by the owner or directly from the owner. It is assumed that the worker performs the work of extracting the sludge stored in the tank regularly or unsteadily. In particular, when the remote monitoring device 200 is configured to be able to transmit post-processing information to the owner (user) of the water treatment apparatus 100 or the cleaning contractor, the owner or the cleaning contractor determines the water treatment status in the water treatment apparatus 100. For example, it is possible to know appropriate information regarding the information, for example, information regarding the next inspection time and cleaning time.

FIG. 2 shows a cross-sectional structure of the medicine cylinder 121 provided in the disinfection tank 120 in FIG. 1 before using the disinfectant, and FIG. 3 shows a medicine cylinder 121 provided in the disinfection tank 120 in FIG. The cross-sectional structure during use of the disinfectant is shown.

  As shown in FIG. 2, the drug cylinder 121 of the present embodiment is configured as a drug cylinder housing having a hollow housing space 121a. Then, a plurality (four in the example shown in FIG. 2) of the disinfectant 122 are stacked and stored in the storage space 121a. The drug cylinder 121 includes a lid member 127 that closes an upper portion of a cylindrical housing extending in the vertical direction. The lid member 127 is mounted on the upper part of the housing during use, and is opened when the disinfectant 122 is filled or maintenance is performed.

It is preferable to ensure the chlorine resistance of the cylinder 121. The drug cylinder 121 here corresponds to the “medicine housing” in the present invention, and the disinfectant 122 here corresponds to the “medicine” and “solid drug” in the present invention.

  In addition, the storage space 121a in the cylinder wall and the outside of the cylinder wall are communicated with a lower region of the storage space 121a, that is, a portion where the lowest disinfectant 122 is located in the cylindrical wall (housing) of the medicine cylinder 121. An opening 123 having an opening shape is provided. The opening 123 is disposed on a flow passage 126 through which water flowing from the upstream processing tank 110 to the disinfection tank 120 flows, and the disinfectant 122 accommodated in the accommodation space 121a of the medicine cylinder 121 is disposed in the disinfection tank. Allow to elute to 120. The opening 123 here corresponds to the “opening” in the present invention.

  According to this configuration, the water to be treated that flows through the flow passage 126 is disposed at the bottom of the plurality of disinfectants 122 that are stacked up and down by the water to be treated that flows through the opening 123 of the drug cylinder 121. Are sequentially eluted into the water to be treated, and are used for disinfection treatment (chlorine disinfection treatment) of the water to be treated. Further, in the present embodiment, the magnet 124 is stacked and placed (placed) on the uppermost disinfectant 122 of the accommodation space 121a. That is, the magnet 124 is supported from below by the uppermost disinfectant 122.

  In addition, the drug cylinder 121 of the present embodiment is configured to be attached to the treatment tank main body 101 via the holding member 125. The holding member 125 is directly or indirectly attached and fixed to the treatment tank main body 101, and is configured as a flat plate-like member extending in a direction intersecting the longitudinal direction of the drug cylinder 121. The holding member 125 includes The first holding part 125a and the second holding part 125b each having an opening are formed. The first holding portion 125a is an opening portion having an inner diameter slightly larger than the outer diameter of the cylindrical drug tube 121. By inserting (inserting) the drug tube 121 into the opening portion, the drug tube 121 is The holding member 125 is held and fixed to the processing tank main body 101. Therefore, the holding member 125 can also be referred to as a drug cylinder fixture for fixing the drug cylinder 121. The second holding portion 125b is provided so as to be connected to the first holding portion 125a, and is an opening portion having an inner diameter into which the medicine detection sensor 140 and the magnetic generator 150 can be integrally inserted. The medicine detection sensor 140 is inserted into the opening portion. When the magnetic generator 150 is inserted (inserted), the medicine detection sensor 140 and the magnetic generator 150 are held on the lower side (outer surface) of the medicine cylinder 121. The 2nd holding | maintenance part 125b may be comprised as two opening parts which can insert the chemical | medical agent detection sensor 140 and the magnetic generation apparatus 150 separately, respectively. As described above, in the present embodiment, the first holding part 125a for attaching the drug cylinder 121 to the processing tank main body 101, and the second holding part for attaching the drug detection sensor 140 and the magnetic generator 150 to the outer surface side of the drug cylinder 121. 125b is integrally formed. In a state where the medicine detection sensor 140 is held by the second holding portion 125 b, the medicine detection sensor 140 is disposed at the lowest position of the disinfectant 122 on the outer surface of the medicine cylinder 121.

  When the holding member 125 having such a configuration is used, the drug cylinder 121 is attached to the processing tank main body 101, and the drug detection sensor 140 and the magnetic generator 150 with respect to the drug cylinder 121 are positioned at predetermined positions. Thus, the function of attaching the drug cylinder 121 to the treatment tank body 101 and the function of attaching the drug detection sensor 140 and the magnetic generator 150 to the outer surface side of the drug cylinder 121 are integrated with the first holding part 125a and the second holding part 125b. This is rational because it is shared by the single holding member 125 configured in a shape.

  In connection with this configuration, a structure is adopted in which the second holding portion 125b of the holding member 125 is omitted, and the medicine detection sensor 140 is directly attached to the outer surface of the medicine cylinder 121 and attached. Also good. Further, in place of the holding member 125 having the above-described configuration, each of the drug cylinder 121, the drug detection sensor 140, and the magnetism generating device 150 is a holder having a holding part for holding (holding) or holding and holding the medicine tube 121 (clamped). Bracket) can also be adopted.

By adopting, the medicine detection sensor 140 may be held in the bottom region of the medicine cylinder 121. In the case of each of the above structures in which the medicine detection sensor 140 is held in the bottom region of the medicine cylinder 121, a structure in which the magnetic generator 150 is directly attached to the medicine detection sensor 140 and attached, or the magnetic generator 150 is used with a bracket or the like. Thus, it is possible to adopt a structure that is independently attached to the drug cylinder 121.

  In the drug cylinder 121 having the above configuration, the disinfectant 122 is consumed by elution with respect to the water to be treated. Therefore, as shown in FIG. 2, the stacking height L in the extending direction of the drug cylinder 121 (vertical direction in FIG. 2). Gradually decreases. Further, as the stack height L of the plurality of disinfectants 122 decreases (disinfectant consumption), the position of the magnet 124 in the accommodation space 121a is displaced downward by its own weight, and the magnet 124 is shown in FIG. Descends in the direction approaching the drug detection sensor 140. Thereby, the intensity | strength of the magnetism which acts on the chemical | medical agent detection sensor 140 from the magnet 124 will increase. As described above, the magnet 124 of the present embodiment is accommodated in the accommodating space 121a of the drug cylinder 121, and moves in the accommodating space 121a so as to approach the drug detection sensor 140 as the disinfectant 122 elutes through the opening 123. The housing position is variable according to the remaining amount of the disinfectant 122. In this case, the amount of change in the accommodation position of the magnet 124 substantially matches the amount of medicine consumed in the vertical direction of the medicine cylinder 121.

Each of the first lead piece 143 and the second lead piece 144 constituting the medicine detection sensor 140 is configured as a magnetic lead piece made of a magnetic material, and is connected to a contact point of one end 143a of the first lead piece 143. The second lead piece 144 is opposed to the contact point of the one end portion 144a of the second lead piece 144 with a gap. The medicine detection sensor 140 is attached to the outer surface side of the medicine cylinder 121 and is configured to operate (turn on) by receiving a magnetism exceeding a specified strength. The drug detection sensor 140 here corresponds to the “drug detection sensor” and the “reed switch” in the present invention, and the two lead pieces 143 and 144 constituting the drug detection sensor 140 are “two” in the present invention. Corresponds to two magnetic lead pieces.

  On the other hand, the first lead piece 143 and the second lead piece 144 are connected to the detection / transmission unit 161 of the communication terminal 160 via the cable 141. The detection / transmission unit 161 of the communication terminal 160 functions to detect the operating state of the medicine detection sensor 140 and transmit information related to the operating state to the server 210 of the remote monitoring device 200. Specifically, the detection / transmission unit 161 is configured as a switch device that switches from an off state to an on state when the medicine detection sensor 140 is activated. On the other hand, the server 210 of the remote monitoring device 200 is configured as a receiving unit that receives the operation state (on state or off state) of the detection / transmission unit 161 via the communication line 170. The detection / transmission unit 161 here constitutes the “sensor detection unit” and the “switch device” in the present invention, and the server 210 of the remote monitoring device 200 here constitutes the “reception unit” in the present invention. The

  The magnetic generator 150 of the present embodiment includes a magnetic coil 152 (also referred to as “electromagnetic coil”) housed in a coil housing 150a. The magnetic coil 152 is connected to the sensor housing 140a while being accommodated in the coil housing 150a, and is connected to the power supply unit 162 via the cable 151. The power supply unit 162 is configured to control energization of the magnetic coil 152 in a sensor determination mode, which will be described later, based on a drive control signal transmitted from the server 210 of the remote monitoring device 200 via the communication line 170. The magnetic coil 152 that is energized and controlled by the power supply unit 162 serves to generate at least a magnet having a prescribed strength that can activate the medicine detection sensor 140. The magnetic coil 152 here corresponds to the “magnetic coil” in the present invention, and the “energization control unit” and the “power supply unit” in the present invention are configured by the power supply unit 162 that controls energization of the magnetic coil 152. The server 210 of the remote monitoring device 200 is a drive unit that operates the power supply unit 162 via the communication line 170 in the sensor determination mode, and constitutes a “drive unit” in the present invention.

  In addition to FIG. 4, FIGS. 5 and 6 are further referred to regarding the specific operations of the drug detection sensor 140 and the magnetic generator 150 described above. Here, FIG. 5 is a cross-sectional view showing a schematic configuration of the drug detection sensor 140 and the magnetic generator 150 of the present embodiment, and shows a state when the drug detection sensor 140 is operated in the normal operation mode. ing. FIG. 6 is a cross-sectional view showing a schematic configuration of the drug detection sensor 140 and the magnetism generator 150 of the present embodiment, and shows a state when the drug detection sensor 140 is operated in the sensor determination mode. ing.

  Regarding the operation of the medicine detection sensor 140, as shown in FIG. 4, when the medicine detection sensor 140 is separated in a region where the magnetism 124 does not reach the specified strength, the medicine detection sensor 140 is in an inoperative state (switch And the contact of the contact of the one end portion 143a of the first lead piece 143 and the contact of the one end portion 144a of the second lead piece 144 does not occur. In this case, does the detection / transmission unit 161 of the communication terminal 160 transmit information indicating that the disinfectant 122 is remaining to the remote monitoring device 200 (the server 210 in FIG. 1) via the communication line 170? Or, the information itself is not transmitted.

  On the other hand, as shown in FIG. 5, in the normal operation mode, the magnet 124 is lowered in the direction approaching the medicine detection sensor 140, and the magnet 124 having a double-sided bipolar structure moves the medicine detection sensor 140 from the upper side to the lower side. When the magnetism received by the medicine detection sensor 140 from the magnet 124 reaches a prescribed strength in the vicinity of the transverse direction, the medicine detection sensor 140 is activated (also referred to as an “on state” with a switch on). Specifically, the first lead piece 143 has one end portion 143a having an N pole and the other end portion 143b has an S pole, while the second lead piece 144 has one end portion 144a. Is the S pole and the other end 144b is the N pole, so that the one end 143a (contact) of the first lead piece 143 and the one end 144a (contact) of the second lead piece 144 are attracted by the magnetic attractive force, They contact each other in the gap (see FIG. 5). As a result, the medicine detection sensor 140 is activated.

  When the medicine detection sensor 140 is activated, the detection / transmission unit 161 connected to the medicine detection sensor 140 via the cable 141 detects that the medicine detection sensor 140 is operated, and communicates the detection information. The data is transmitted to the remote monitoring device 200 (the server 210 in FIG. 1) via the line 170. In the remote monitoring device 200, information related to the remaining amount of the disinfectant 122 is output by the output unit 240 based on the information received by the server 210. The output information of the output unit 240 in this case includes the presence / absence and remaining amount of the disinfectant 122, the consumption amount and consumption speed of the disinfectant 122, information indicating that the disinfectant 122 is lost, and the disinfectant 122 is likely to be lost. Information indicating that the lower limit control value has been reached, information indicating that the disinfection process has been performed normally, information indicating that the disinfection process has not been performed normally, and disinfectant associated with consumption of the disinfectant 122 Various information relating to the consumption of the disinfectant 122 such as the replenishment timing and the replenishment amount is widely included. In addition, regarding the output mode of the output unit 240 in this case, it is possible to appropriately use a mode in which characters, numbers, designs, etc. are displayed on a display, a mode in which sound, alarm, etc. are output to a speaker. Accordingly, it is possible to prompt the user or administrator of the water treatment apparatus 100 to inspect the disinfection tank 120 and replenish the disinfectant 122 in the disinfection tank 120. In this case, the output unit 240 detects the disinfectant 122 when the magnet 124 comes close to the drug detection sensor 140 and the detection / transmission unit 161 detects that the drug detection sensor 140 is activated by the magnetism of the magnet 124. The information output unit outputs information about the remaining amount, and corresponds to the “first information output unit” in the present invention.

  In the present embodiment, it is preferable that the outer diameter of the magnet 124 is substantially the same as the inner diameter of the drug cylinder 121 or slightly smaller than the outer diameter of the disinfectant 122. Furthermore, it is preferable to adopt a configuration in which an arcuate R portion is provided at the corner of the magnet 124 or a configuration in which the entire shape of the magnet 124 is curved with the upper side recessed. According to such a configuration, when the disinfectant 122 is sequentially consumed from the lower stage side and the magnet 124 is lowered, the magnet 124 is prevented from being caught on the inner wall of the drug cylinder 121, and the magnet 124 is smoothly lowered. Thus, information related to the remaining amount of the disinfectant 122 can be accurately detected by the medicine detection sensor 140.

  Regarding the operation of the magnetic generator 150, when a drive control signal is not transmitted from the server 210 of the remote monitoring device 200 to the power supply unit 162 via the communication line 170, or when a stop signal is transmitted, the power supply unit 162. Is set to the OFF state. At this time, since the magnetic coil 152 does not generate magnetism, the medicine detection sensor 140 does not operate.

  In contrast, in the sensor determination mode illustrated in FIG. 6, the server 210 of the remote monitoring device 200 transmits a drive control signal to the power supply unit 162 via the communication line 170. Thereby, the switch of the power supply unit 162 is set to an ON state. At this time, the magnetic coil 152 generates magnetism of a prescribed strength that can activate the medicine detection sensor 140, and the sensor determination magnetism from the magnetic coil 152 acts on the medicine detection sensor 140.

  At this time, if the medicine detection sensor 140 is in a normal state, the medicine detection sensor 140 is activated by the magnetism of the magnetic coil 152 acting. Accordingly, information indicating this operation state of the medicine detection sensor 140 is transmitted from the detection / transmission unit 161 to the server 210 of the remote monitoring device 200 via the communication line 170. In the remote monitoring device 200, based on the information received by the server 210 in the sensor determination mode, the output unit 240 outputs information indicating that the medicine detection sensor 140 is operating normally. The output information of the output unit 240 in this case may be information that directly suggests that the medicine detection sensor 140 is normal, or the disinfectant 122 that is output in the normal operation mode described above. Information that indirectly suggests that the medicine detection sensor 140 is normal, such as information on the remaining amount, may be used. In particular, when information regarding the remaining amount of the disinfectant 122 is used as the output information of the output unit 240, the output unit 240 only has to output the same output information in the normal operation mode and the sensor determination mode. It becomes possible to simplify the system configuration related to the unit 240.

  On the other hand, if the medicine detection sensor 140 is in an abnormal state (for example, a failure state), even if the magnetism of the magnetic coil 152 acts, the medicine detection sensor 140 does not operate. Accordingly, information indicating this non-operating state of the medicine detection sensor 140 is transmitted from the detection / transmission unit 161 to the server 210 of the remote monitoring device 200 via the communication line 170, or information relating to the medicine detection sensor 140 itself. Is not sent to the server 210. At this time, in the remote monitoring device 200, the output unit 240 outputs information indicating that the medicine detection sensor 140 is abnormal. In this case, the output information of the output unit 240 is preferably information that directly suggests that the medicine detection sensor 140 is abnormal.

  Thus, the output unit 240 in this case detects and transmits the operating state of the drug detection sensor 140 by the magnetism applied from the magnetic coil 152 when the power supply unit 162 controls energization of the magnetic coil 152 in the sensor determination mode. When the unit 161 detects, the information output unit outputs information indicating whether the drug detection sensor 140 is normal or abnormal based on the detection information of the detection / transmission unit 161. 2 information output unit ”.

  In the present embodiment, the server 210 of the remote monitoring device 200 periodically transmits a drive control signal to the power supply unit 162 via the communication line 170 at regular intervals or regular intervals, thereby periodically. It is preferable to perform the sensor determination mode and automatically determine whether the drug detection sensor 140 is normal or abnormal. Further, instead of this form or in addition to this form, it is possible to adopt a form in which the administrator manually controls the server 210 at any timing to perform the sensor determination mode.

  As described above, according to the water treatment device monitoring system 10 of the present embodiment, the user or administrator of the water treatment device 100 can confirm that the drug detection sensor 140 is operating normally or the drug detection sensor 140 is In particular, it is possible to easily detect the failure of the medicine detection sensor 140 itself or the abnormality in the communication path of the detection information detected by the medicine detection sensor 140 by the remote monitoring device 200 at a remote location. In addition, the remote monitoring structure in the remote monitoring device 200 makes it possible to detect collectively the operation states of the chemical detection sensors 140 provided in the plurality of water treatment devices 100, which is reasonable.

  Further, according to the above-described embodiment, the magnetism for sensor determination is simply applied to the drug detection sensor 140 in the sensor determination mode by the magnetic coil 152 arranged in connection with the sensor housing 140a of the drug detection sensor 140. It becomes possible to do.

  In addition, according to the above embodiment, the magnet 124 having a double-sided bipolar structure is close to the medicine detection sensor 140 (reed switch) in a direction crossing from the upper side to the lower side. The operation range in which the two magnetic lead pieces 143 and 144 contact each other in the gap due to the magnetism received from the magnet 124 (typically, the magnet) is adopted by adopting a configuration in which the 144 receives the magnet 124 from the magnet 124 to contact each other in the gap. The operation range regarding the direction crossing the vertical movement direction of 124 can be expanded as much as possible, which is effective in increasing the operation accuracy of the reed switch.
