摘要： PURPOSE:To eliminate the influence of the atmospheric pressure being different due to a meteorological condition and altitude, etc., by calculating a ship speed, based on a difference between pressure applied to a semiconductor pressure sensor at the time of stop, and pressure applied to the semiconductor pressure sensor at the time of movement. CONSTITUTION:A reference value setting means 4 stores pressure applied to an opening 35 at the time when a ship is stopped, as a reference value. A speed operating means 5 inputs a digital voltage signal from an ADC 2, and first of all, subtracts said reference value from its value. The value which has been derived in such a way corresponds to a pressure value obtained by subtracting the atmospheric pressure from the pressure applied to the opening 35, namely, dynamic pressure generated due to a movement of the ship, and subsequently, a speed operating means 5 calculates a vessel speed from this value. In such a way, only a value corresponding to the dynamic pressure based on the movement of the vessel can be fetched purely, and an exact ship speed can be derived.

摘要： PURPOSE:To detect a ship speed within the whole ship speed region with high accuracy, by changing over a ship speed to the detected ship speed based on the output of a ship speed detection means within a low speed region and changing over the same to the detected ship speed based on the electric signal by a semiconductor pressure sensor. CONSTITUTION:The output voltage of a magnetic current meter 2, is converted to digital voltage signal by an A/D converter 3 to be outputted to a speed operation means 9. Next, when the ship speed calculated by the means 9 is a predetermined change-over value or less, said calculated ship speed is outputted as a ship speed signal to the given to a ship speed display means 11 and the speed display corresponding to the content of said ship speed signal is performed. When it is judged that the calculated ship speed is the change-over value or more, the digital voltage signal based on the output voltage of a semiconductor pressure sensor 1 is taken in and the calculation of a ship speed is performed by the means 9 and this calculated ship speed is outputted as a ship speed signal and the speed display corresponding to the content of said ship speed signal is performed on a speed display means 11. By this method, a ship speed can be detected within the whole ship speed region with good accuracy.

摘要： PURPOSE:To decide the charged state of a battery and a discharging state or a charging state by providing a means for detecting an abnormality based on a battery voltage lowered at the time of driving a starter and a means for detecting the abnormality based on a deterioration frequency entering a reference alarm voltage range at the time of a steady use. CONSTITUTION:The first abnormality detecting means for detecting the abnormality of the battery based on the battery voltage lowered at the time of driving the starter and the second abnormality detecting means for detecting the abnormality of the battery based on the deterioration frequency of the battery voltage entering the predetermined reference alarm voltage range in a comparatively long sampling time at the time of the steady use are provided in an alarm decision means 2. When the abnormality of the battery in at least one thereof is detected, an abnormal alarm is displayed on a display means 3. Thereby, the charging state of the battery is decided by the first abnormality detecting means to decide the charging or the discharging of the battery by the second abnormality detecting means and can be easily monitored the abnormality to an arbitrary battery.

摘要： PURPOSE:To confirm the liquid level in a housed tank without need for removing a cowling by providing a transparent portion on the cowling and forming the tank wall opposite to this transparent portion of the tank so as to be able to see the inside through the wall. CONSTITUTION:The wall thickness of a tank wall of nylon, etc., forming the front face of the body of a tank 54, particularly, the portion opposite to the transparent body 64 of a top cowling 18 is formed thinner than that of other tank walls, thereby forming a transparent portion. Also, a baffle plate is installed in the tank in a position leaving a slight space from the transparent portion and along the shape thereof. Hence, the liquid level in the tank 54 can be externally visually confirmed via the transparent body 64 of the top cowling 18 and the transparent portion of the tank 54, while further improving the confirming property due to the baffle plate.

摘要： PURPOSE:To prevent erroneous display within a low speed region, by determining a ship speed region of a predetermined speed or less to the low speed region and displaying a pattern meaning a low speed in place of a detected ship speed within the low speed region. CONSTITUTION:The voltage applied to a semiconductor pressure sensor 1 is converted to a digital voltage signal by an A/D converter 2 to be inputted to a speed operation means 4. Next, in the means 4, it is judged whether a read digital signal is a predetermined value or less. When the digital signal id the predetermined value or less, a calculated ship speed is judged to be 5km/h or less to output a low speed signal to a speed display signal. That is, for example, '-' is displayed on the display part in the means 6 on the basis of the outputted low speed signal. A user receives information such that the calculated ship speed is within a low speed region of 5km/h or less by the '-'display.

摘要： PURPOSE:To reduce the error generated between an actual ship speed and a detected ship speed, by judging the sudden speed reduction of a ship on the basis of the detected ship speed and correcting the detected ship speed so as to allow the same to approach the actual ship speed when the sudden speed reduction of the ship is judged. CONSTITUTION:The voltage applied to a semiconductor pressure sensor 1 is converted to a digital voltage signal by an A/D converter 2 to be guided to a speed operation means 4. Next, an operation data map 5 is utilized in the means 4 to calculate the present ship speed v0. This ship speed v0 is written in a memory S0 and the previous calculated ship speed v1 confronting through a sampling cycle T is read through a memory S1. Then, the judge of sudden speed reduction is performed on the basis of the difference between the previous ship speed v1 read through the memory S1 the ship speed v0 written in the memory S0. When sudden speed reduction is judged, a predetermined value A is subtracted from the ship speed v0 written in the memory S0 to obtain a corrected ship speed and the ship speed signal showing said corrected ship speed is outputted to a speed display means 6. By applying the correction of a ship speed by this way, ship speed display approaching an actual ship speed is performed.
