Abstract

PURPOSE:To prevent a moving object from following an erroneous course, by recording absolute position information on a recording medium in accordance with manual setting of absolute position information indicating a preliminarily determined position. CONSTITUTION:Rotation shafts of rear wheels RW1 and RW2 of a car or the like which are rotated and driven independently of each other are provided with pulse generators PG1 and PG2, respectively. A counter (CT) 1 counts the output of the pulse generator PG1 and inputs the counted value to multipliers M1 and M2 to calculate a movement distance. A CT3 detects the difference between outputs of pulse generators PG1 and PG2 and gives it to a correcting circuit CRT1, and this difference is given to a sine circuit SIN and a cosine circuit COS through a correcting circuit CRT2 and is multiplied in multipliers M1 and M2 and is displayed on an XY recorder XYR as a movement course. When absolute position information is set to a set switch SSW, this information is given to the circuit CRT2 through a bearing signal generator SG to initialize it correctively. Thus, an absolute position is detected on the recorder to prevent erroneous movement.

The azimuth determination circuit ADC in FIG. 2 receives the unique number signal of each transmitting station from the controller IIDEM included in the correction circuit COM, and determines which direction (azimuth) the vehicle is moving.
The decision is made by determining whether the object is moving. For example, the third

The desired azimuth signal from 0° to 360' is derived and scanned. The operation of the above configuration will be explained below.

FIG. 7 is a locus showing an example of a moving route drawn by a moving route recording device to which the present invention is applied. The operation will be described below with reference to FIGS. 2 and 3.

The count value for each unit time (1 second) from the normal mode counter CT1 is calculated by the multiplier M1. It is input to M2.

On the other hand, counter CT3 continuously calculates the difference (PGI-PO
2) is counted and input to the correction circuit CRT1. If there is a correction signal output from the AND gate G2 at this time, the correction circuit CRTI subtracts this correction 11g1I from the difference from the counter CT3, etc.
The corrected movement of the vehicle 17 is a differential output that correlates to the unidirectional angle. The sine circuit SIN outputs the correction circuit 11cRT1 via the correction circuit CRT2 (
l1 minute) is converted into an angular change in the direction of movement, and the sine value at this angle is determined and input to the multiplier M1. Cosine circuit CO8, correction circuit CR via correction circuit CRT2
The T1 output h (difference) is received, converted to a movement direction angle, and the cosine value of this angle is input to the multiplication 11M2.

The multiplier M1 calculates the moving distance per unit time based on the number of pulses of the pulse generator PG1 per unit time inputted as described above, multiplies the calculated moving distance by the sine value, and calculates XY. 1 multiplier M2 that derives a coded signal representing the Y-axis component (Y in FIG. 7) of recorder A coded signal representing the X-axis component (X in FIG. 7) of the XY recorder XYR is derived.

The accumulator AC1, which receives the Y-axis component coded signal from the multiplier 11MI, accumulates the sequentially input Y-axis 18-components, and the accumulator AC2 counts the X-axis components.

The difference in positive correlation is related to the moving speed of the vehicle; if the speed is fast, the intervals are large (rough), and if the speed is slow, the corners are small (
It can be easily understood that recording is done by counting the number of pulses generated per unit time.

For example, even though the vehicle is moving in a straight line, the difference in the counter CT3 (difference in the moving direction WA) caused by the single load state of the vehicle or the air condition of the vehicle tires )
In order to check and correct the difference in the counter CT3 when the vehicle is moving in a straight line, the check mode setting key CHK is pressed. Accordingly, the flip 7O block FF is set and the latch circuit RC
The held state that was held during H's previous check mode is cleared. Since the AND gate G1 is activated by the set output of the flip 70-tube FF, the average value output from the counter CT2 (important for the moving distance) is
It is input to the counter CT4 via this AND gate G1. Counter CT4 derives a count-up output in response to receiving the output from counter CT2 and counting pulses (20,000 pulses, for example, 200-minutes for a predetermined moving distance). The count-up output from the counter CT4 resets the τ flip-flop FF, activates the latch 1111RcH, and activates the delay circuit DLY, thereby activating the AND gate G2. Therefore, the latch circuit 11Rc
H reads and holds the difference (PGl-PO2) counted by the counter CT3 at this time. The parallel-serial converter 100N that receives the output of the latch circuit RCH converts this difference into a pit series coded signal.
give to Here, the frequency division 11FD is, for example, 1/100
The frequency is divided into 1 and applied to AND gate G2.

Therefore, the correction circuit CRT1 is given the frequency-divided 11FD output via the AND gate G2, and the correction circuit CRTI
corrects the difference in correlation to the moving direction angle every 1/1 revolution of the wheel based on the output of the frequency divider FD.

Correction mode 1 Now, in the correction circuit COM, the 41st! l(b)
When the absolute geographical position as a correction signal is input to accumulators AC1 and AC2 from the receiving side shown in , this correction signal is converted to D/A converter 11DA1 . D2l- Converted to an analog value by A2. Therefore, the absolute position is plotted on the map M in a corrective manner.

If the direction of movement of the vehicle is known in advance based on the road on which it is traveling, manually switch the setting switch SS.
The above-mentioned information from the azimuth signal generation 118G when the setting switch SSW is automatically set by the azimuth signal from the azimuth determination circuit ADC that has received the unique number signal from the transmission jiiTR8. (
The azimuth angle signal is given to the correction circuit CRT2. Therefore, the correction circuit CRT2 receives the input angle signal and corrects the difference by correctively initializing the difference correlated to the moving direction angle from the counter CT3 and the correction circuit CRTI based on the angle signal.

For example, when the north N switch is turned on, a direction signal is generated.
When a coded signal of "0°" is input from l5G,
Even if a difference indicating a certain angle is inputted from the correction circuit CRTI, the correction 22-corrects this difference to a difference representing "0@". Therefore, tN
When the switch is turned on, the sine 11!181 N and the na sine circuit CO8 will represent the corrected ``oo''.
The sine and cosine values are calculated by 1-II, respectively. This "correction mode 2" is particularly effective in cases where there are relatively few direction changes, such as on a 2-way road.

Roughly speaking, the coded signals from the accumulators AC1 and AC2 are transmitted to the central controller 11 and the 1avI! 1
11 (Sky 1) 1ll IP 111 Traffic 11 Report Center etc., each vehicle and aircraft can use 1111w4@ at the airport.

No. 811 is an illustrative diagram of a preferred embodiment of the setting switch SSW of the present invention. This setting switch SSW is configured in a rectangular (diamond) shape, so the driver can
Without looking at the arrangement of switches for the identification of W, each - a separate switch N, NE, E.

In the above-described embodiment, the setting switch SSW was used to set the direction, such as North N or East E, but if it is mounted on an aircraft, it will be set as shown in Figure 9. may be configured.

That is, since the orientation of the airport runway is known in advance and the flight of the aircraft is extremely constant, the setting switch SSW is provided with a setting switch specific to each airport runway. For example, switch BT1 sets the specific heading of the runway in Osaka, switch BT2 sets the specific heading of the runway in Tokyo, etc., and switch BT3 sets the specific heading of the runway in Chitose. Switch BT to set Nago

generates an angle signal indicating the bearing of the Osaka runway. The correction circuit CRT2 uses the angle signal specific to the sky I to correct the moving direction. According to this embodiment, aviation-
When installed in a vehicle, azimuth correction is easy and convenient. Further, in the above-described embodiment, the check mode is set when the vehicle is traveling in a straight line, but this may be changed depending on the condition of the road or the like.

Furthermore, "the left and right wheels are rotated independently" mentioned in this specification means that the left and right wheels are completely independent, such as in an aircraft or a rear car, and the left and right wheels do not rotate in any way. In addition to cases in which the wheels are rotated without any correlation, for example, there are cases in which the drive wheels of an automatic umbrella are linked by differential gears, and although the rotation is the same in principle, there are differences in the rotation radius, load, and other changes. This also includes cases where a difference in left and right rotation occurs.

As described above, this embodiment provides the following unique effects.

-(1)- Since the number of pulses corresponding to the one-to-one rotation of the wheel is generated, that is, the rotation of the wheel is detected by the number of generated pulses.
Very precise and accurate traversal paths can be recorded.

(2) Since a check circuit is provided for correction based on the rotational error 25- of both left and right wheels when traveling in a straight line, the moving direction angle is sequentially corrected to achieve more accurate recording.

(3) Since a correction @ route is provided for corrective plotting based on the absolute geographical position, the absolute position of the vehicle can be known, and erroneous movement can be prevented.

(4) A correction circuit, an azimuth signal generator, and a setting switch to correct the moving direction (azimuth).

Since a direction determining circuit is provided, the direction of movement can be corrected depending on the road on which the vehicle is traveling, and more accurate recording can be achieved.

(5) Automatic vehicle movement by sending coded signals to a central monitoring device! - can be achieved. Furthermore, since the data is transmitted to the central monitoring device using a coded signal, it can be transmitted in a narrow frequency band.

As described above, according to the present invention, in response to manual setting of absolute position information representing the predetermined digit 1,
Since the absolute position information is recorded on the recording medium, by confirming the absolute position 26, it is possible to prevent the inconvenience of the moving object moving along the wrong route.
