原理で高度を求める高度計も存在する。[Prior Art] Conventionally, there is an aneroid type barometer that converts the deformation of a diaphragm due to changes in atmospheric pressure into the rotation of a pointer, determines the atmospheric pressure based on the rotation angle, and determines and predicts the weather. There are also altimeters that measure altitude using the same principle.

圧計が存在する。Furthermore, a pressure sensor that sends out an electrical signal in accordance with the atmospheric pressure, an A/D converter that converts the analog electrical signal sent out by the pressure sensor into a digital electrical signal, and an A/D converter that uses the digital electrical signal to determine the atmospheric pressure at each measurement position. and a barometric pressure calculating means and an altitude calculating means for calculating the altitude, a barometric pressure state determining means for determining the rise and fall of the barometric pressure based on the output of the barometric pressure calculating means, and outputs of the altitude calculating means and the barometric state determining means, respectively. There is an altimeter-cum-barometer that is equipped with a mote switching means that allows display of altitude and atmospheric pressure, as well as rise and fall of the atmospheric pressure, on the same screen.

ため、同一ダイヤフラムを用いた気圧計により、天気を
判断予測することと高度を求めることとは不可能であり
、それぞれ独立の気圧計を設ける必要がある。[Problems to be solved by the invention] Since a barometer or an altimeter that utilizes the deformation of a diaphragm is equipped with mechanical contacts, if it is installed in a vehicle that is subject to vibration and shock, such as a car, the vibrations and (■j The contacts may be damaged and destroyed by the shock, resulting in inaccurate readings or no operation at all.Furthermore, the range of atmospheric pressure fluctuations on the ground and at altitudes of several thousand meters is different. Because the size of the range is different and the sensitivity is different depending on the atmospheric pressure, it is impossible to judge and predict the weather and determine the altitude using a barometer using the same diaphragm, so it is necessary to install independent barometers for each. be.

である。In addition, the altimeter-cum-barometer, which incorporates a pressure sensor that sends out electrical signals depending on the atmospheric pressure and can switch between displaying altitude and pressure on the same screen, has solved the problem caused by vibration and shock, but it does not distinguish between stopped and moving cars. Since the system is designed to measure the atmospheric pressure without changing the altitude and display the altitude, atmospheric pressure, and whether the atmospheric pressure rises or falls on the same side, it is possible to display the change in altitude and atmospheric pressure on the same side. This means that it is dangerous to use this display to judge changes in the weather. Also, because the display of weather changes is extremely simple, it is difficult to accurately predict and judge weather changes using this display.
It is.

一定時間以後はそれを抹消させるようにしである。FIG. 4 shows the operation and display of weather judgment/prediction and the display of altitude in flowchart 1. That is, based on the respective outputs of the atmospheric pressure calculation means 3, the vehicle running state determination means 5, and the clock means 6, a series of atmospheric pressure data collected at regular intervals in the past while the vehicle is stopped is transmitted to the weather determination and prediction means 7.
In addition to recording the temporal change pattern of atmospheric pressure as a temporal change pattern of atmospheric pressure, a plurality of standard atmospheric pressure temporal change patterns (Fig. 5A to
), the weather at that point in time and subsequent changes in weather are predicted and displayed on the display screen 8a of the display as shown in FIG. A series of barometric pressure data collected at regular intervals in the past is designed to incorporate the latest data one after another, while erasing the oldest data. In addition, if the stopping time is short and the series of atmospheric pressure data necessary for determining and predicting the weather is not complete, the system will wait while collecting new data until it is complete. . On the other hand, it is also possible to display the altitude by pressing the mode changeover switch 9a of the mode changeover means 9, if necessary. While driving, the atmospheric pressure changes due to changes in altitude and horizontal position, so even if a series of atmospheric pressure data is collected at regular intervals, the weather at that point and the subsequent weather can be determined and predicted based on that data. Since this may give erroneous results, the screen 8a of the display 80 is mainly switched to altitude display as shown in FIG. 2 during that time. However, until a certain time after departure, the latest judgment prediction results are left in the weather judgment prediction means 7 so that the weather judgment prediction before departure can be switched and displayed.
It is designed to be deleted after a certain period of time.

ことを示している。Next, a plurality of standard atmospheric pressure change patterns over time will be explained with reference to FIG. The vertical axis of the coordinate axes in Figure 5 shows atmospheric pressure, and the horizontal axis shows time. A indicates that the atmospheric pressure rises and then falls shortly after, indicating that the weather is downhill. B indicates that the atmospheric pressure rises and then continues for a while. The atmospheric pressure will be maintained and the weather will continue to be sunny. C means that the atmospheric pressure is rising and the weather is changing from cloudy to sunny.
D: The atmospheric pressure is about to rise from a low state and the rain will stop; E: the atmospheric pressure will remain constant and the same weather will continue; F: the atmospheric pressure will change from falling to rising and the rain will stop. At G, the atmospheric pressure decreases and remains low for a while.
H indicates that the rain will continue, H indicates that the atmospheric pressure will drop and it will turn into rain, and I indicates that the atmospheric pressure will begin to drop from a constant value and the weather will worsen.

It is also possible to do so.

Furthermore, the means for determining and predicting the weather becomes extremely rational and its display becomes clear, further improving the reliability of weather determination and prediction while the vehicle is stopped. Furthermore, even while the vehicle is stopped, the latest forecast of the weather at the time of the stop can be displayed on the screen for a certain period of time after departure, and it is also possible to roughly predict the weather while driving.
