Abstract

The anti-tank directional mine is equipped with a firing trigger or detonation control using different sensors, such as laser, acoustic, infrared or optical fibre sensors, plugged into the mine and electronic housing. These sensors (SE) have a common module (10) for the automatic sensor control (ASS), forming the interface for the mine and sensor signals. The sensor signals and also the signals of the mine electronics, each having a matching unit (11, 15), are normalised, so that they can be processed in the automatic sensor control and formed into a pulse according to the target. A programmable timing unit (13) controls the operation of each sensor and feeds the sensor pulses to a target counting logic (14), together with pre-selector switches (16, 17) and an indicating unit (18) integrated with the common module. ADVANTAGE - Can employ variety of sensors without need for making changes in processing system.

In the prior art, such mines are for special Applications equipped with special sensors for this. The mine is now to be used for several applications so-called multisensors are to be used, which are not only very expensive, but also a large one additional expenditure on electronic components and a require directions.

The basic idea of the present invention is that of an anti-tank mine to design that there is the possibility of different sensors for triggering the ignition point or for activating the To be able to use directional mine, depending on the battlefield situation. In order to be able to accomplish this, it is now provided that once as Link between mine and sensor is an automatic sensor control (ASS) and the LL sensor unit can be adapted train and as a separate component with electrical connector add to the mine.

As illustrated in FIGS . 1 and 2 of the drawing, between the directional lead RM and the sensor SE intended for use, a unit 10 in the form of an automatic sensor control - hereinafter referred to as ASS - is used, which is the interface for the mine and sensor-specific signals forms, each with an adaptation circuit 11 , 15, the sensor signals and the signals of the mine electronics are adjusted so that they are processed in the automatic sensor control and formed into a pulse 12 per detected target. Furthermore, a programmable timer 13 is assigned in the ASS 10 , which controls the operating time of the respective sensors SE and supplies the sensor pulses to a target counting logic unit 14 during their operating time.

The ASS 10 is connected via a plug 19 and a cable 21 to the plug socket se of the directional lead RM and also to a plug 20 and a cable 21 a with the respective sensor SE. Furthermore, the ASS 10 is provided with a switch 15 for electronically blocking the pulses Ir returning to the mine in the event of a target recognition message by the sensor SE.

The RM straightening lead, which is provided with a plug connection on its electronics housing, is now positioned in the so-called field of application. The various loose sensors are adapted to this plug-in connection as needed and required. In order to ensure that the mine functions properly, the mine as such must always be supplied with the same information, although different sensors are used. For this purpose, a converter 32 is provided for the use of an LL sensor and the automatic sensor control ASS 10 is provided for all other sensors.

As illustrated in FIG. 3, the LL sensor unit 30 consists of a plug 34 , cable 33 , converter 32 and the LL sensor 31 , which - as FIG. 4 shows - is designed as a loop. Here, the converter 32 forms the electrical-optical interface of the system. In it, the electrical 500 Hz pulses are converted into light signals via a transmitter diode. These light signals are converted back into 500 Hz pulses in the receiving diode via the LL loop and return to the mine.

The returning impulses are continuously monitored in the mine. Absence - For example, by driving over or interrupting the LL loop more as three pulses, the firing is activated.

The unit shown in Fig. 3 with any electronic sensor SE also consists of connector 19 , connecting cables 21 , 21 a, the ASS 10 and the sensor SE. Here the ASS 10 forms the interface for the mine and sensor specific signals. If a target is detected by the sensor SE, the ASS blocks the pulses returning to the directional lead RM via the electronic interrupter and after three pulses are missing, the ignition is activated.

For the signals supplied by the different sensors SE, an adaptation circuit 11 is provided in the ASS, which adjusts them and delivers one pulse per target. The operating time of the sensor SE is set in the ASS via a downstream timer 13 . For this purpose, a preselection switch 17 is arranged, which can program the timer 13 between one and forty days. The end of the programmed operating time is made visible by means of a device 18 for operating status display which is controlled by the timer 13 and which can be, for example, a disengaging push button with a display or illuminated sign. As a result, the alignment lead can now be saved, recorded and used again regardless of the sensor type used. During the operating time of the sensor SE, its pulses are supplied via the timer 13 to the target counting logic 14 , which is also programmable from the outside with a preselection switch 16 in such a way that it only triggers the electronic switch for interrupting the directional mine when, for example, the third and not the first goal is to fight.

From Fig. 3 it can also be seen that the converter 32 is provided with a strain relief for the electrical cable 33 and the handling takes place by the winding coil 35 with a friction brake for the LL fiber. The plug cables 21 and 21 a are also strain relieved. The ASS works as follows:

The signals sent and received by the directional lead RM are adapted in the ASS so that their values correspond to those of the LL diodes of the mine sensor electronics. The directional mine continuously sends and receives a pulse sequence of 500 Hz in a loop. If this pulse sequence is interrupted for more than three pulses, the directional mine triggers the shot. The electronic interrupter switch / adaptation 15 interrupts the pulse train for at least three pulses. The interrupter is controlled by the SE sensor of any type, the signals of which are adapted and decoupled. With the timer 13 , the duration of the operating time of the respective sensor SE and thus also the directional mine is determined. The setting for this is done via the manually adjustable switch 17 in steps of 1 to 40 days. As a visible display 18 for the operating state, a push button with indicator is proposed, which is in the active position in the pressed state. After the set time has elapsed, the push button automatically disengages and the directional lead is "disarmed", which means that the lead can be reset, transported to another location or returned to the warehouse or depot.

By means of a manually adjustable pre-selection switch 16 programmed target counting logic 14 , the number of incoming target detection pulses from the sensor SE is counted and depending on the target number set - for example between 1 and 8 - the signal to the electronic interrupter in switch 15 is switched through. The power supply of the ASS takes place via the power source (battery) of the directional mine as soon as the mine is sharpened. If necessary, the electronic sensor SE is also supplied by the alignment mine via the ASS. The ASS is connected via shielded, strain-relieved and as short as possible cables 21 , 21 a, the length of which must however be selected so that the countermass is not influenced by cable pull when firing, at least not before the warhead flies freely.

Due to the measures proposed here, a directional mine has now been designed, which is secured against eviction considerably higher. The minefield formed with it becomes much less sensitive to interference and, depending on the combat situation, a wide variety of sensors can be used or replaced quickly and easily. Thanks to special combination measures, an optimally effective minefield can be built up from all possible sensor types. The use of expensive multisensors is no longer necessary. In FIGS. 5a to 5f, the terminal block are circuit diagrams shown for different sensor types.
