摘要： A combustion furnace control apparatus for which an operation control system that ensures the combustion safety of the combustion furnace can be constructed easily. Interlocks pertaining to the safe operation of a combustion furnace are classified as a 1st interlock pertaining to the safe operation of the overall combustion furnace, a 2nd interlock pertaining to the combustion environment of a combustion zone and a 3rd interlock pertaining to the combustion of a burner. Whereby, a common control module judges the state of the 1st interlock and controls the overall operation of the combustion furnace; a combustion zone control module, receiving a control signal from the common control module, operates to judge the state of the 2nd interlock and prepare the combustion environment for the combustion zone; and a burner control module, receiving a control signal from the combustion zone control module, operates to judge the state of the 3rd interlock and control the operation of the burner.

摘要： An RTC, having a crystal oscillator of different characteristics from those of a crystal oscillator, is provided, and the pulse period of the pulse signal from the RTC and the pulse signal based on the crystal oscillator are compared to detect a fault in the crystal oscillator. As a result, even if, for example, located in a high temperature environment, the degrees to the decrease in frequency will be different, thus making it possible to detect reliably a fault in the crystal oscillator.

摘要： A system for transmission of signals between modules wherein, for example, it is possible to transmit reliably, between modules, information relating to, for example, the actuation of safety devices. A transmission module for transmitting a pulse signal of a specific period, which indicates the existence of information, generates, in time division, pulse signals by a plurality of signal generating units that are provided in parallel, and then combines these pulse signals into a single time series pulse signal. Then an attempt is made to output this pulse signal towards a receiving-side module through a relay for controlling the output, and the signals appearing at a normally-open terminal and at a normally-closed terminal of the relay are monitored to determine whether or not there is a failure, where the generation of the pulse signal is stopped when a failure is detected.

摘要： A relay failure detecting device able to detect reliably a fault in a relay circuit that provides alternating current power to a load through a relay that is a double-pole switch. Individual common terminals of first and second relays are connected individually to a pair of outputs terminals of an alternating current power supply, individual normally-open terminals of the first and second relays are connected to a pair of power supply input terminals, and a dummy load that is driven by the alternating current power supply through a diode between the individual normally-closed terminals of the first and second relays is provided. A fault in the first and second relays is evaluated from the state of operation of the dummy load when the first and second relays are not driven.

摘要： Two controlling devices, namely a combustion controlling device controlling the combustion of a combustion furnace, and a safety controlling device checking the operation of the devices wherein the operations are controlled by the combustion controlling device. This enables safer control of combustion because if there is a fault in either the combustion controlling device or the safety controlling device, a process can be performed by the other device to stop the combustion. Additionally, because the controlling device for controlling the structural elements that control the combustion in the boiler system and the controlling device for operational checks of the outputs from those structural elements are separate, if there is a failure in any of the structural elements or controlling devices, that failure can be detected reliably, enabling safer control of the combustion.

摘要： Power that is supplied to a primary coil of a transformer from a DC power supply that is connected to the primary coil is modulated based on continuous pulses supplied from a microcontroller, and power that is induced between terminals of a secondary coil of the transformer is supplied to a relay. A large driving current can be supplied to the relay thereby, thus making it possible to reduce the ripple component, and, as a result, to achieve stabilized operation.
