Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention uses a switching unit for a gyro compass system (hereinafter referred to as a ``gyro system'') in which a plurality of gyro compass systems are installed and output the azimuth measured by azimuth transmitting parts. The present invention relates to a multi-gyro compass system configured to display directions on an external device by switching between the two, and more particularly to a multi-gyro compass system characterized by improving the configuration and operability of the switching unit.

<Prior Art> Each azimuth signal is a synchro angle signal output from a transmitting synchro, and this synchro angle signal is mechanically coupled such that each transmitting and receiving synchro corresponds to one degree of azimuth for one synchro rotation. Because of this, there is no one-to-one correspondence with the azimuth angle. In other words, the azimuth angle signal from the transmitting synchronizer only contains information of 1 degree, so for example 10.5 degrees.
20.5° also becomes the same azimuth signal.
In other words, these azimuth angle signals are simply switched using a switching element (for external equipment with reception synchronization that operates on azimuth signals that only contain information within 1 degree, information within 1 degree is not possible). (as it can only operate), there will be a mismatch between the azimuth of the switching side gyro system and the azimuth of the external device. In order to prevent this mismatch, when switching, it is necessary to first tune the external equipment using a tuning device provided to prevent mismatch, and then switch to the other gyro system. The following description will be made using a block diagram showing the configuration of the multi-gyro compass system shown in FIG.

In FIG. 3, reference numeral 1 indicates an azimuth angle signal θa through which a signal (deviation voltage) from an azimuth transmitting unit 1a consisting of a master star compass, for example, is transmitted through an amplifier 1b, a servo motor 1c, a gear mechanism 1d, and a transmitting synchronizer 1e.
A first gyro system 2 outputs a signal from the azimuth transmitter 2a as an azimuth signal _θb via an amplifier 2b, a servo motor 2c, a gear mechanism 2d, and a transmission synchronizer 2e. 3 is a switching unit which inputs the azimuth angle signals θ _a and θ _b and switches and outputs one of the azimuth angle signals θ _d . This switching unit 3 detects the azimuth deviation between the azimuth angle signals θ _a and θ _b and outputs an alarm signal that lights up the alarm lamp 4 when this deviation exceeds a set limit value, for example. The azimuth signals θ _a , θ _b and the azimuth signal θ _c for tuning from the tuning transmitter 3 c are connected to the section 3 a and mutually switched by the switching signal (manual) α to produce the azimuth signal after switching. and a switching element 3b that outputs θ _d . Reference numeral 5 denotes an external device such as a synchro repeater comprising a reception synchronizer, which is configured to display the azimuth based on the azimuth signal θ _d from the switching unit 3.

The switching operation of the multi-gyro compass system configured as described above will be explained below.

Now, the azimuth signal _{θ a} output from the first gyro system 1 is connected to the a contact of the switching element 3b,
It is assumed that the tuning signal from the tuning transmitter 3c is connected to the a contact of the switching element 3b, and the azimuth signal θ _b output from the second gyro system 2 is connected to the c contact of the switching element 3b.

The display on the synchro repeater 5 is changed from the direction signal θ _a to θ _b
In order to switch to
Switch b from a contact to b contact. As a result, the synchro repeater 5 is operated by the azimuth signal θ _c generated by the transmission synchronization from the tuning transmitter 3c. Therefore, the transmission synchronizer of the tuning transmitter 3c is manually operated so that the orientation of the second gyro system 2 and the synchro repeater 5 coincide. At this time, since the direction of the gyro system can generally be known from the compass card and pointer provided in the direction transmitter, the direction of the tuning transmitter 3 can be adjusted while looking at this direction. After this, the switching element 3b is further switched from the b contact to the c contact on the second gyro system 2 side using the switching signal α.

<Problems to be Solved by the Invention> However, this conventional multi-gyro compass system requires a tuning transmitter including a transmitting synchronizer in the switching unit, and also requires the troublesome tuning operation of switching the gyro system. There are problems such as the need to do it manually each time. The present invention has been made in view of the problems of the prior art, and has a multi-gyro system configured to automatically complete tuning of a plurality of gyro systems without providing a tuning transmitter for tuning operations. The purpose is to provide a Gyro compass system.

<Means for Solving the Problems> A multi-gyro compass system of the present invention for achieving the above-mentioned object includes a tuning signal for synchronizing a plurality of gyroscope systems and an external device;
A signal for switching between this tuning signal and a signal from the azimuth transmitter is output to the plurality of gyro systems, and the gyro switching element is connected to the plurality of gyro systems and can mutually switch them. A tuning device that outputs a signal to switch the switching element.
A switching signal output section is provided, and when there is a switching signal from the tuning/switching signal output section, the tuning signal is output from the plurality of gyro systems to the external device via the gyro switching element. Therefore, the present invention is characterized in that it has a configuration that allows the plurality of gyro systems and the external equipment to be easily synchronized.

<Examples> Examples of the present invention will be described in detail below based on the drawings. In the following drawings, parts that overlap with those in FIG. 3 are given the same numbers, and their explanations will be omitted.

In FIGS. 1 and 2, 10 is a first gyro system, and 20 is a second gyro system.

Switching elements _10c , _20c are connected to contacts _n1, n2, and a tuning signal j from a tuning/switching signal output unit 6, which will be described in detail later, is connected to contacts n1, _n2 , and these switching elements 10c, 20c. An azimuth signal output unit 10 that is connected to the common contact of the switching elements 10c and 20c and outputs azimuth signals θ ₁ and θ ₂ by inputting the signals selected by the switching elements 10c and 20c.
d, 20d. 30 is a switching unit which inputs the azimuth angle signals θ ₁ and θ ₂ and outputs either the azimuth angle signal θ ₄ . This switching unit 30
consists of a tuning/switching signal output section 6, a gyro switching element 7, and an azimuth deviation detection section 3a. tuning·
When the switching command signal γ is input, the switching signal output unit 6 performs synchronization between the synchro repeater 5 and the first and second gyro systems 10 and 20. For example, a tuning signal j, which is an arbitrary azimuth signal, and a signal i ₁ from the azimuth transmitter 10c, 20c,
The switching elements _10c and 20c
output to the first and second gyro systems 10, 2.
Azimuth angle signals θ ₁ and θ ₂ from 0 are connected to contacts e and f, and a signal k for switching between contacts e and f is output to a mutually switchable gyro switching element 7.

In such a device, the gyro system 1
When switching from 0 to the gyro system 20, the procedure is as follows.

When the switching command signal γ is issued, the tuning/switching signal output unit 6 outputs the first and second gyro systems 10,
20, the switching elements 10c and 20c are contacts
A switching signal q for switching from m ₁ and m ₂ to contacts n ₁ and n ₂ ,
Tuning signal j is output to contacts n ₁ and n ₂ . Therefore, the azimuth signal output sections 10d and 20d output tuning signals j having the same value, and the synchro repeater 5
also follows in sync. That is, at the time when the following operation is completed, the first and second gyro systems 10,
The directions of the synchro repeater 20 and the synchro repeater 5 all match the direction of the tuning signal j from the tuning/switching signal output section 6. In addition, sufficient time for tracking (the maximum value of the tracking time is when the rolling ball rotates 180 degrees, so at least this time should be the minimum value) is set using, for example, a timer. After sufficient time for this follow-up,
From the tuning/switching signal output section 6 to the gyro switching element 3
Outputs a signal k that switches contact e of 0b to f.
Thereafter, the tuning/switching signal output unit 6 further outputs a switching signal q to the switching elements 10c, 20c to switch the contacts n ₁ , n ₂ to m ₁ , m ₂ . As a result, the azimuth signal θ ₂ from the second gyro system 20
This allows the synchro repeater 5 to perform a follow-up operation. Here, the azimuth signal output section is configured so that even if there is a large difference between the signal from the azimuth transmission section and the tuning signal, the difference can be gradually corrected, so the synchro repeater will not step out. The switching element in the gyro system can therefore be simply switched.

By the way, the present invention is not limited to the configuration shown in FIG. For example, the number of gyro systems is not limited to two, and even when three or more sets are installed, the configuration of the present invention can be easily realized. In addition, components other than the mechanical system of the present invention, such as the azimuth transmitter or the switching unit, may be constructed using discrete circuits as shown in FIG. 1, or may be constructed using a microprocessor or the like. It goes without saying that you may do as you like.

<Effects of the Invention> As described above in detail with reference to the embodiments, the multi-gyro compass system of the present invention does not require a tuning transmitting part for tuning after switching, unlike the conventional system. Since tuning can be performed by applying the transmitting function of each gyro system without having to do so, the number of constituent parts can be reduced, and the entire device can be made smaller. Furthermore, when switching the gyro system, the only operation required is inputting a switching signal to the switching unit, so the switching work can be simplified.
