Here, the facility controller 16 transmits data to the information management server 38 by the transmitter 32 at regular intervals, for example, every 5 minutes.

A user terminal 42 on the manager side managing the above-mentioned device accesses the management server 38 via the Internet communication network 41. And this management server 3
The data stored in 8 is taken out, and the data is displayed on the display device of his terminal. As a result, the state of the liquid in the storage tank 11 of the facility at a remote place is known.

From the situation of the storage tank 11 obtained through the internet communication network 41, if the quantitative information or the qualitative information of the liquid in the storage tank 11 is abnormal, the management server 38 is passed through the internet communication network 41. Is transmitted to the controller 30 of the facility via the data communication network 37, the base station antenna 36, and the antenna 33 from the management server 38. Then, the controller 30 opens any one of the corresponding solenoid valves 27, 28, 29, and injects a predetermined amount of the chemical solution into the storage tank 11 from any of the tanks 21, 22, 23, and thereby the storage tank 11 Operate so as to avoid the abnormal state of the liquid inside. Note that this operation may be performed artificially through the user terminal 42, or may be automatically processed according to a software program installed in the information management server 38 or the user terminal 42.

It is possible to call attention to the observer.

Quantitative or qualitative management of the liquid in the storage tank 11 is carried out by using a factory pond, a hospital bathtub, a pool, a return water tank, a park pond, a boiler internal storage tank, and a building air conditioner. It can be widely used for storage of cooling and heating water, medical water tank, industrial water tank, water and sewage equipment, wastewater treatment equipment, etc. The quantitative management items controlled here may be the water level and the flow rate. The qualitative control items may be temperature, amount of bacteria, transparency, amount of impurities, pH, oxygen reduction potential (ORP), conductivity, residual chlorine concentration, dissolved oxygen (DO) concentration, etc. It is widely applicable to the facility. Further, instead of the electromagnetic valves 27 to 29 for injecting the drug solution into the storage tank 11, a pump may be used to inject the drug solution.

The information management server 38 is a common integrated management computer commonly used by a plurality of user terminals 42. Then, when it is desired that the information of the facility corresponding to the plurality of user terminals 42 is not seen by other users, only the information of the own facility can be acquired by the password or ID as shown in FIG. I can not see the data of.

In this operation, when the user terminal 42 accesses the management server 38 via the Internet communication network 41, the management server 38 receives the password or ID. Then, it is confirmed whether the passwords or IDs match. If they match, the data of the facility corresponding to the user terminal 42 is transmitted. On the other hand, if there is a password or ID mismatch,
Do not send data. This ensures mutual confidentiality when a common information management server 38 is used for a plurality of user terminals 42.

Next, with such a communication system, an alarm operation can be performed. As shown in FIG. 7, the server 38 may capture the data, compare the data to a reference value, and generate an alarm signal if the data is higher than the reference value. This alarm signal is transmitted from the server 38 to the fax 44 from the target server 43 through the internet communication network 41. Alternatively, it is transmitted from the Internet communication network 41 to the portable information terminal 47 through the router 45 and the antenna 46. Therefore, when an abnormality occurs, it can be accurately transmitted to the monitor.

FIG. 8 shows the server 38 having a quantitative or qualitative control function of the liquid in the storage tank 11. That is, the server 38 transmits the storage tank 11 through the data communication network 37.
The data is taken from the measuring instruments 12 to 15 and the data is compared with the reference value. Then, the injection amount of the chemical liquid is calculated from the deviation value between the two, and the amount of the chemical liquid supplied from the chemical liquid tanks 21, 22, 23 is calculated. According to this calculation, the opening time of the electronic valves 27, 28, 29 is calculated, and a signal for opening the corresponding solenoid valves 27 to 29 for the time corresponding to this opening time is sent from the data communication network 37 to the controller 30 of the facility. Supply to.

Therefore, the controller 30 uses the server 38.
The electromagnetic valves 27 to 29 are opened in response to the control signal from the tanks and the chemicals are supplied from the corresponding tanks 21 to 23 into the storage tank 11. This changes the quantitative or qualitative state of the chemical liquid in the storage tank 11. The change in this qualitative state is measured by the measuring instruments 12 to 15, and the controller 16
Is sent to the server 38 through the data communication network 37, and a closed loop control operation is performed between remote places.
