Abstract

PURPOSE:To simplify a device, and to contribute to safe operation by using a pair of gyros only corresponding to the progressive direction and an accelerometer and obtaining true acceleration, in which the effect of gravity by a gradient, etc., only in the progressive direction is eliminated, by arithmetic operation. CONSTITUTION:When a train 5 is accelerated at acceleration alpha on an up-grade at an angle theta, a gyro 3 detects an angular velocity. A moving-body acceleration detector 1 loaded on the train 5 successively integrates an output from the gyro 3 while using a line grade theta at the time of stoppage at a known station as an initial value, and computes the grade under the state of a figure. The indicated value alpha of an accelerometer 2 displays the sum of the acceleration alphaof the train and the component of force alphag lowering on the grade of the acceleration g of gravity, thus indicating the acceleration alpha of the train 5 by alpha=alpha'-gsintheta, then arithmetically operating the acceleration alpha by the moving-body acceleration detector 1. Accordingly, true acceleration is obtained by a simple device, and safety operation by an overcrowded railway schedule is conducted.

BACKGROUND OF THE INVENTION The present invention is an improvement of an inertial navigation system for an aircraft or the like for land vehicles. Some conventional inertial navigation systems measure acceleration in a three-dimensional direction on a rotary gyro called a platform and double-integrate the acceleration to obtain a position. Recently, an accelerometer is fixed to the machine body, and the posture (displacement) of the accelerometer is measured by an optical fiber gyro or the like to obtain a moving distance on a three-dimensional fixed coordinate.
Even when these devices are applied to a moving body on a two-dimensional plane, the same ones as those of the three-dimensional moving body have been used because of the gradients of front, rear, left and right of the traveling path, curves and the like.

Land vehicles are generally equipped with rotating wheels. Normally, the acceleration, speed and moving distance can be easily calculated by rotating the wheels. However, on railways, gliding and idling occur quite frequently, and each time there is an error in speed and travel distance. Recently, a system has been developed that detects the position of each train and controls the distance between trains, and automatically brakes when it approaches abnormally, and reliable and highly accurate train position detection is required. When slipping or slipping occurs, position detection without wheels is required. In the prior art, three sets of gyros and accelerations for measuring rotational displacement are required to cope with three-dimensional changes, which is not only expensive but also requires complicated arithmetic processing.

When the accelerometer is installed in the traveling direction of the moving body, the accelerometer indicates the acceleration of the moving body as long as it moves horizontally. However, when going up and down a slope, it is strongly affected by gravity. For example, the acceleration of a train is usually about 0.5 m / s 2 , but on the uphill of 30/1000, it is affected by gravity of 0.3 m / s 2 and is 60%.
Error of. Since the position is represented by the double integral of acceleration, it becomes an unusable error in just a few seconds. Therefore, the gradient is measured with a gyro or stored in advance as data, and the influence of gravity is removed by calculation.

Many inexpensive accelerometers and gyros have drift that cannot be ignored. Glides and slips occur sporadically, and normally, that is, when there is no slip, the rotation of the axle provides extremely accurate acceleration. Therefore, these drifts are corrected by the acceleration at this time.
Conversely, since the drift can always be corrected with high accuracy, it is possible to use an inexpensive and somewhat less accurate one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a moving body acceleration detecting device will be described with reference to FIG. The train 5 is accelerating an uphill gradient of an angle θ with an acceleration α. The gyro 3 detects the angular velocity. The mobile body acceleration detection device 1 sequentially integrates the outputs of the gyro 3 with the known track slope when the train is stopped at the station as an initial value, and calculates the slope θ in the state of FIG. 1. The instruction value α ′ of the accelerometer 2 indicates the sum of the acceleration α of the train and the component force αg that descends the gradient of the acceleration g of gravity, and therefore the acceleration α of the train 5 is expressed by equation (1). G in the equation is the value of the acceleration g of gravity, and the sign g and the value g are shared. The same applies to α, αg, and θ below. The mobile body acceleration detection device 1 performs the same calculation to detect the traveling direction acceleration.

The claim 5 will be described with reference to FIGS. 2 and 3. The moving body position detecting device 6 in FIG. 2 calculates the acceleration, the velocity, and the moving distance from the pulse from the axle rotation pulse generator 4 when there is no slipping slip. At the same time, the drift of the angular acceleration detected by the gyro 3 is calculated.
The drift of the accelerometer 2 is calculated only when the train 5 stops at the station.

In these equations, Δα and Δω are drift values, ω is an angular velocity that is considered to be correct, ω ′ is an indication value of the gyro 3, θ is an elevation angle of the current line gradient, and θ1
Represents a known track gradient when the station is stopped, and ΣωΔt represents an integrated value of ω after the station is stopped.

When the train is stopped at the station, the acceleration α in the traveling direction of the equation (2) is naturally zero, and the gradient θ (θ when the train is stopped is θ1) and the acceleration g of gravity are known. The total drift Δα is obtained. Further, since ω is also zero in the equation (3), the indicated value ω ′ of the gyro 3 indicates the drift Δω.

Next, in step 3, the acceleration from the axle is taken in, and this is substituted into α in equation (2), and the gradient θ is calculated back from the indicated value α'of the accelerometer and the initially obtained drift Δα. Further, the angular velocity based on the axle rotation is obtained from the difference from the previous calculated value of θ, and the difference between the gyro indicated value ω ′ and this angular velocity, that is, the drift at that time (Δ
ω '). Theoretically, this drift can be used as Δω in equation (3), but since the acceleration is a discontinuous value, an accurate drift is obtained by the deviation of the detection timing between the acceleration due to the axle and the acceleration due to the accelerometer. Since there is a possibility that there is no possibility that the drift does not change abruptly, the angular velocity drift Δω is corrected according to equation (5) by correcting a part of the change amount.
However, μ in the equation is set to a correction factor of 1 or less.

For example, when a change of 4.5 km / h or more per second or -6 km / h or less per second is detected, it is determined that slipping slip has occurred, and in step 8, the moving distance obtained in step 5 is changed to the moving distance by the axle.

Means for correcting the detection value of the moving body or the elevation angle detecting means, interrupting the correction when the wheel slips idle, and complementing the moving body position by regarding the traveling direction acceleration output from the moving body acceleration detecting device as the moving body acceleration. The moving body position detecting device according to claim 3 or 4, wherein.
