Features of the small and medium water and sewage measurement and control device according to the present invention for achieving the above technical problem,

A measuring unit measuring a state value of water and sewage; A micro panel unit configured to monitor and control the measurement unit by an input signal of the state value transmitted from the measurement unit; And a computer for monitoring the input signal transmitted from the micro panel unit through an internet network and transmitting a control signal to the micro panel unit.

The micro panel unit includes a direct current power supply for supplying direct current power; An input / output card unit for receiving an input signal of the state value transmitted from the measurement unit, and outputting the control signal transmitted from the computer to the measurement unit; A central processing unit controlling the input signal and the control signal inputted and outputted through the input / output card unit; And a serial communication unit for transmitting the input signal to the computer and receiving the control signal transmitted from the computer.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a block diagram showing the configuration of the small and medium water and sewage measurement and control apparatus according to an embodiment of the present invention, Figure 3 is a block diagram showing the configuration of the micro-panel portion shown in FIG.

As shown, the present invention is largely composed of a measurement unit 10, a micro panel unit 60, the Internet network 70 and the computer 40.

The measurement unit 10 is a flow meter 11 for measuring the flow rate of water and sewage, a water meter 12 for measuring the water quality, a water gauge 13 for measuring the water level, a pressure gauge 14 for measuring the pressure and the temperature It includes the thermometer 15 to specify.

The micro panel unit 60 includes a DC power supply unit 61, an input / output card unit 62, a central processing unit 63, and a serial communication unit 64.

The DC power supply unit 61 supplies 24 [V] DC power to the central processing unit 63.

The input / output card section 62 includes an analog input card section 62a, a digital input card section 62b, a pulse input card section 62c, an analog output card section 62d, and a digital output card section 62e. It consists of.

The analog input card unit 62a receives an analog signal of DC 1-5 [V], 4-20 kHz transmitted from the measurement unit 10, and the digital input card unit 62b and the pulse input card unit. 62c receives a voltage-free contact signal transmitted from the measurement unit 10.

The analog output card unit 62d outputs an analog control signal of DC 1-5 [V], 4-20 Hz transmitted from the computer 40 through the Internet network 70 to the measurement unit 10, The digital output card unit 62e outputs a voltage-free contact signal transmitted from the computer 40 to the measurement unit 10 via the Internet network 70.

The central processing unit 63 controls the analog signal transmitted from the measurement unit 10, the voltage-free contact signal, and the analog control signal transmitted from the computer 40 through the Internet network 70, The voltage contact signal is controlled to allow normal operation.
