Description

  The present invention relates to a sewer remote monitoring system suitable for use in, for example, remote monitoring of sewage flow rate.

  Sewerage usage fees for large households such as general households, bathhouses, hotels, hospitals, condominiums, food processing factories, etc. are set to an amount obtained by multiplying a certain rate by the water supply usage fee. However, this sewage usage fee does not reflect the amount of sewage actually discharged by households and facilities. Therefore, attempts to measure the actual discharged sewage flow rate and reflect the measured value in the sewage usage fee are spreading, and a flume flow meter is generally used for the measurement (Patent Document 1). reference).

Japanese Patent Laid-Open No. 2006-114366

  By the way, as one of the factors that hinder the expansion of the above-mentioned attempts, there is a mistrust that the above-mentioned measurement is not necessarily performed accurately. That is, there is a concern that the measurement result of the sewage flow rate by the flow meter may be tampered with and the sewage usage fee may be calculated lower than the original.

  The present invention has been made in consideration of the above-described matters, and an object thereof is to provide a sewer remote monitoring system capable of improving the reliability of the measurement result of the sewage flow rate.

  In order to achieve the above object, a sewer remote monitoring system according to the present invention remotely monitors the flow rate of sewage flowing through each monitoring point by a plurality of users via a server terminal installed in a communication network. A sewer remote monitoring system for generating a flow rate data from a sewage water level, a communication module connected to the flow meter for transmitting the flow rate data, and a signal from the communication module And a server terminal for storing flow rate data for each flow meter, the server terminal corresponding to the identification information that the user inputs at the time of access to the user who has accessed through the communication line The flow rate data from the flow meter is viewed (claim 1).

  In the sewer remote monitoring system, a water level sensor for measuring a sewage water level is connected to the flow meter via an isolator, and an uninterruptible power supply device may be connected to the flow meter.

  In this invention, the sewer remote monitoring system which can improve the reliability of the measurement result of a sewage flow rate is obtained.

  That is, in the sewer remote monitoring system of the invention according to each claim of the present application, the flow rate of sewage flowing through the monitoring point can be monitored by a plurality of users from different positions, and thus the transparency of the measurement result of the sewage flow rate Reliability can be increased.

  In the sewer remote monitoring system according to the second aspect of the present invention, since the trouble is hardly caused in the flowmeter due to the provision of the isolator and the uninterruptible power supply, the reliability of the measurement result of the sewage flow rate can be achieved even with such a configuration. Will increase.

It is explanatory drawing which shows roughly the structure of the sewer remote monitoring system which concerns on one embodiment of this invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  The sewer remote monitoring system shown in FIG. 1 is for remotely monitoring the flow of sewage flowing through each monitoring location by a plurality of users U via a server terminal 2 installed in a communication network 1. The flow meter 3 for creating flow rate data from the water level of the sewage, the communication module 4 connected to the flow meter 3 for transmitting the flow rate data, and receiving a signal from the communication module 4 And a server terminal 2 for storing flow rate data.

  Here, a water level sensor 6 for measuring the water level of the sewage is connected to each flow meter 3 via an isolator 5 and an uninterruptible power supply device 7 is connected. And the flow measuring device 8 which consists of the flow meter 3, the communication module 4, the isolator 5, the water level sensor 6, and the uninterruptible power supply device 7 is each installed corresponding to the monitoring location of a sewage flow rate.

  Moreover, what is necessary is just to use what is suitable for the measurement of the flow volume of a sewage as the flowmeter 3, For example, the flume type flowmeter as described in patent document 1 can be used, and as the water level sensor 6, for example, An ultrasonic water level sensor can be used.

  Then, the server terminal 2 identifies the identification information (for example, individually for each user U in advance) that the user U inputs at the time of access to the user U who has accessed via a communication line (whether wired or wireless). The flow rate data from the flow meter 3 corresponding to the assigned ID number or the like is browsed. The user U starts a browser (browsing program) installed in a client terminal (commercially available personal computer, smartphone, etc.), for example, and inputs a URL indicating a storage location of predetermined flow rate data in the server terminal 2. By doing so, the server terminal 2 can be accessed, and the server terminal 2 requests the accessing user U to input identification information. In this case, in order to further increase safety , And password input (passwords can be set and changed by each user U).

  Here, as the user U, for example, a user U1 who is a sewerage user who is obligated to pay a sewerage usage fee generated at a monitoring location, a user U2 who is a sewerage administrator who manages sewerage, and a flow meter 3 or a user U3 who is a manufacturer of the flow rate measuring device 8 and a user U4 who is an administrator of the entire sewer remote monitoring system (or server terminal 2) of the present embodiment. The contents that can be browsed are different for each of the users U1 to U4 (the contents that can be browsed by each user U are restricted by associating the identification information individually assigned to the user U with the flow rate data, etc. It is like that).

  That is, the user U1 normally uses the sewer used by each as a monitoring location, and the flow rate data from the flowmeter 3 installed at this monitoring location (for example, each water level obtained every 1 to 5 minutes and Instantaneous flow rate, accumulated flow rate per day, cumulative flow rate value since the flow meter 3 was installed, etc., maintenance management information related to the flow meter 3 (for example, history information such as maintenance contents and work date / time, current use or replacement) Only browsing of the product number of each previous member can be performed.

  The user U2 can only browse the flow rate data from the flow meter 3 installed in each jurisdiction. Specifically, for example, as shown in FIG. 1, if there are three jurisdictions A, B, and C, a user U2 who has jurisdiction only in jurisdiction A is from the flow meter 3 in that jurisdiction A. Any flow rate data can be browsed, but flow rate data from the flow meters 3 in other jurisdictions B and C cannot be browsed.

  The user U3 can browse the flow rate data from all the flow meters 3.

  The user U4 can browse the flow rate data from all the flow meters 3 and view / change the maintenance management information related to all the flow meters 3.

  According to the sewer remote monitoring system configured as described above, the flow rate of sewage flowing through the monitoring point can be monitored by a plurality of users from different positions. Can be increased. Further, the flow data from the flow meter cannot be changed, and the provision of the isolator 5 and the uninterruptible power supply device 7 makes it extremely difficult for the flow meter 3 (flow measurement device 8) to have a problem. Therefore, the reliability of the measurement result of the sewage flow rate is also enhanced by such a configuration.

  Further, the flow rate data from the flow meter 3 is also useful for the user U1 such as a general household or facility manager who is obligated to pay a sewerage charge, and can be used for water saving. For the user U2, it is also information to prevent flooding due to guerrilla heavy rain and to develop a sewerage facility. For the user U3 who is the manufacturer of the flow meter 3 (flow measurement device 8), It has very high utility value, such as information that contributes to grasping performance and improving quality.

  In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.

  For example, the server terminal 2 uses the water meter meter reading value input by the user U (U1, U4, etc.), the sewage usage amount calculated from the meter reading value, and the actual sewage usage amount obtained by the flow meter 3. And may be configured to be comparable.

  In addition to the above-described functions, the server terminal 2 includes, for example, a browsing function for status information (information indicating whether the flow meter 3 is in a normal state, an abnormal state, or a maintenance state), a flow rate For example, a file retrieval function for retrieving data as a CSV file, a management function for each user U information, a system error management function for managing the contents of the flow data from the flow meter 3 and data storage defects, the flow meter 3 An abnormality notification function for notifying the user U that an abnormality has occurred may be provided, and the use of each function may be limited to only an arbitrary user U.

  And it cannot be overemphasized that you may combine suitably the modification given in this specification.
