Description

  The present invention relates to an equipment update method and an equipment update notification device, and more particularly to an equipment update method for an existing manhole pump control panel and an equipment update notification device.

  A control panel is installed in the vicinity of the manhole in which a plurality of submersible pumps for conveying the sewage flowing from the upstream sewage pipe to the downstream sewage pipe are accommodated.

  The control panel is electrically connected to an input pressure type water level meter installed in the manhole and converts the output signal of the water level meter into a predetermined water level signal. A control circuit for starting or stopping the submersible pump based on a water level signal input from the water level converter connected to the water level, a water level signal input from the water level converter that is backed up by a battery, and a pump control signal input from the control circuit Function block such as a reporting device that transmits manhole pump facility operation information to the outside based on the above, and a terminal block in which a plurality of terminals for connecting a submersible pump, a control circuit, a water level gauge, a water level converter, etc. are arranged And a control panel housing for accommodating them.

  The water level converter supplies power to a water level gauge with a built-in pressure sensor, and converts the water level detected by the energized current into water level signals necessary for controlling the submersible pump, that is, the stop water level LWL, the start water level HWL, the high water level HHWL, etc. In addition, it is an electronic circuit that converts it into an analog measurement signal for notification, for example, a current signal of 4 to 20 mA or a voltage signal of 1 to 5V.

  Normally, when a failure occurs in a component that constitutes such a control panel, it is restored by replacing it with a failed component unit. However, when the useful life of each functional block elapses, it is replaced with a functional block unit. .

  In Patent Document 1, in preparation for a large-scale refurbishment when the control method itself by the control circuit needs to be changed, the cost required for the update facility can be reduced by effectively using the existing control panel facility. Submersible pump control units and submersible pump control panels have been proposed.

  However, such major refurbishment requires a corresponding cost, electronic circuits such as water level converters and reporting devices have a shorter service life than control circuits composed of relay circuits, etc., and equipment replacement costs are reduced For these reasons, there are many cases where these water level converters and notification devices are replaced in units of functional blocks, and there are cases where only the notification device is incorporated into an existing control panel in which the notification device is not incorporated.

Reference numeral 60 denotes a lightning arrester (arrester).

  The electromagnetic switches 54 and 55 are connected to the induction motors M1 and M2 of the submersible pump 12 via the earth leakage breakers 51 and 52, respectively. Between phase leakage breakers 51 and 52 and induction motors M1 and M2, phase-advancing capacitors C1 and C2, overload detection circuits 56 and 57, and current transformers 58 and 59 are interposed. , 57 and current transformers 58, 59 are input to the control circuit 2.

  Further, an AC 200 V single-phase AC is branched from an AC 200 V three-phase AC, and is connected to relay circuits 61, 62, and 63 through a control power breaker 53. Relay circuit 61, 62, 63 is controlled by control circuit 2, and heater 64, cooling fan 44, Patlite (registered trademark) 66, etc. are turned on or off.

  Further, the AC 200 V single-phase alternating current is input to the AC / DC converter 67 via the control power supply breaker 53. The AC / DC converter 67 generates a DC 24V DC voltage, and the DC 24V DC voltage is further input to the DC / DC converter 68 to generate a DC 5V DC voltage.

  The DC voltage of 24V DC is used as a driving voltage for the water level gauge 15, and the DC voltage of DC 5V is supplied as a control power source to the water level conversion unit 3 and the reporting unit 4 equipped with a microcomputer. If the control circuit 2 is provided with an electronic circuit such as a microcomputer, a DC voltage of DC 5 V is also supplied to the control circuit 2.

  The water level conversion unit 3, the notification unit, and the battery 4a hatched in FIG. 2 serve as a notification device 4 that is a newly installed functional block in place of the existing water level converter and the notification device. Thus, if the reporting device 4 incorporates the water level conversion unit 3 that performs signal processing of the water level sensor for controlling the submersible pump 12, it can be connected to an AC 200V three-phase AC load, and the existing control panel Therefore, the single-phase 200V commercial power source that has been drawn in to 1 becomes unnecessary, and a lightning arrester for that purpose is also unnecessary.

It is configured to be able to.

  For example, when the breakers 51, 52, and 53 are normal, the water level signal reaches the pump activation water level HWL, but corresponds to the contact signal or contact signal of the electromagnetic switches 54 and 55 that drive the submersible pump 12. When it is detected that the signal to be input is not input to the notification unit, it is determined that an abnormality has occurred in the electromagnetic switches 54 and 55. Since such abnormal information is reported to a distant monitoring device, quick maintenance becomes possible.

  With the above configuration, when the commercial power supply fails, a DC 24V DC voltage is supplied from the battery 4a to the water level meter 15 and the DC / DC converter, the water level conversion process is performed by the water level conversion unit, and the conversion output is reported. Stored in the memory of the department and reported to the outside. In other words, the water level can be measured even during a power failure.

  In order to reduce battery power consumption in the event of a long power failure, the microcomputer of the reporting device enters sleep mode, wakes up every predetermined time with a real-time clock, detects the water level, and the value is abnormal It is preferable to be configured to report to the outside and then return to the sleep mode. In the sleep mode, it wakes up with an access signal from an external monitoring device and returns operation information and abnormality information of the manhole pump device, and then the sleep mode. It is preferable to configure so as to return to
