Abstract

The invention discloses a singlechip-based small routing inspection controller for a fire pump group, belonging to the control equipment of fire pumps. The controller is characterized by comprising a control board based on a singlechip MCU (Micro Controller Unit), a display screen, a light-emitting diode signal lamp group and a photoelectric coupler all connected with a display drive circuit in the MCU, a button group of a switching value shaping circuit in the MCU, an input signal wiring terminal board connected with an analog signal processing circuit and the switching valve shaping circuit in the MCU, a relay group connected with a relay drive circuit in the MCU, an output signal wiring terminal board driving a fire-fighting control cabinet water pump group alternating current contactor by the relay group, an asynchronous communication serial interface wiring terminal connected with a communication drive circuit in the MCU, and a power interface wiring terminal connected with a power circuit in the MCU. After trial, in comparison with the prior art, the controller gets rid of the control devices, such as a variable frequency speed controller, thus, both product cost and use cost are lowered; and the control system is simplified due to the singlechip, and further the reliability of the control system is improved effectively.

Description

technical field [0001] The invention belongs to control equipment for fire-fighting water pumps, in particular to a small-scale inspection controller for fire-fighting water pump groups based on a single-chip microcomputer. Background technique [0002] The prior art document 1ZL95207683.7 discloses a microcomputer-controlled automatic patrol inspection fire water supply equipment control cabinet, "its feature is to include: a programmable controller, the system program in which makes the microcomputer Execute the automatic inspection program, and set the frequency output of the frequency converter to a low frequency constant. When executing the fire program, the programmable controller controls the closing of the relay group connected to the industrial frequency power supply to make the fire pump run at the rated speed ; A microcomputer controller controls the power-on, start and stop of the frequency converter during automatic inspection, and controls the relay groups conn...
