From the DE 199 56 961 A1 For example, a method is known for controlling the effect of vibrations on the shaping and compaction of concrete products made in shock vibration finishers. For this purpose, measured values of motion variables are detected which correlate with the degree of compaction and / or the compaction time and are recorded on the vibratory paver. The method makes it possible to compare nominal values and actual values recorded at reference points with each other and, if necessary, to detect deviations and, if necessary, to influence the corresponding quantities of motion. The detection takes place via acceleration sensors and a measured value processing assigned to them.

From the EP 1 064 131 B1 For example, a concrete compacting arrangement is known which comprises vibrating units, each of which generates a signal corresponding to a vibration generated by the vibration generating means on the tray. This signal is passed on to a control or regulation, via which a frequency converter is controlled. Furthermore, it is provided to connect the individual controllers to one another via data lines in order to enable a mutual exchange of information, wherein it is additionally proposed to connect to the data line a master computer via which each individual controller can be centrally controlled.

The known from the prior art solutions regularly offer only partial solutions, which are prone to failure in particular with regard to the data transmission.

The invention has for its object to develop a device for monitoring and control or regulation of a machine which has a suitable for harsh environmental conditions data acquisition and is also insensitive to shocks and freely positionable.

This object is achieved in connection with the preamble of claim 1 according to the invention by the characterizing features of claim 1. The features mentioned in the dependent claims advantageous embodiments and modifications of the invention are possible.

In the device according to the invention, data can be interchanged wirelessly via a radio link between the sensors and an electronic control loop, which forms an evaluation and control unit or control unit, via transmission and / or reception devices. The data include measured variables, such as vibration frequency, vibration amplitude, vibration duration or pressing pressure, with which the upper mold part acts on the lower mold part. If necessary, setting of the batch, such as the filling quantity, the moisture content or the proportion of additives, are also recorded as data in a block forming machine. Due to the inventive design of the device, it is possible to dispense with data lines which are highly susceptible to failure under harsh conditions, for example in stone making and their pre-admission is particularly problematic especially to a frequently changing component, for example a molding device. The use of sensors designed for radio data transmission is also advantageous in particular with regard to a component which has to be replaced regularly, for example a forming device, since the sensor can also be used outside the forming device for logistical purposes, for example for detecting the storage location of the forming device , Such a sensor can already during production the mold device for production control or production monitoring or manufacturing documentation are used.

The invention further provides for the sensor to be equipped with its own power supply in order thereby to be able to dispense with the supply of energy and to eliminate another potential source of interference and to simplify handling.

Furthermore, the invention provides for equipping the sensor with a data memory with which data determined by the respective sensor itself and / or data determined by another sensor can be stored. When using several such sensors, a redundant data storage is possible.

According to the invention, it is also provided to equip the sensor with a processor, which carries out the processing of data, which were determined by the respective sensor itself and / or were determined by another sensor. Such equipment of the sensors allows pre-processing of data, for example, to reduce amounts of data that must be forwarded.

According to the invention, the sensor has its own energy source, which is designed in particular as a rechargeable battery. In such a structure can be made of proven standard components, which have long lifetimes.

It is also envisaged to charge the energy source by vibrations generated by the stone-forming machine during stone production and to use a generator for this purpose. In this way, in the Operation of the individual brick forming machine to be made at regular intervals power supply.

It is also envisaged to integrate the electronic control loop into the radio chain and thus to realize an end point or a starting point for the radio chains.

The invention provides for using a sensor which sets its transmission power to one or more of the neighboring sensors achievable with the lowest transmission power in order to load the energy source as little as possible.

According to the invention, it is also provided, by means of the processor arranged in the sensor, to carry out a check of the data received from a second sensor on the basis of own data and / or on the basis of the data received from a third sensor and to report the result. As a result, regardless of the electronic control circuit maladjustments and failures of individual sensors can be detected and possibly compensated.

Finally, the invention provides for using sensors which enable non-contact measurement on the basis of received or transmitted and received beams or waves. As a result, for example, the arrangement of a sensor on or in the molding device can be dispensed with, so that it is not necessary to retrofit older molding devices.

The invention makes it possible to orient the control of the stone forming machine to the conditions actually prevailing on the molding device and thus optimally treat each stone set in the stone forming machine. This makes it possible, in particular, when starting a stone forming machine or changes in the behavior or the composition of the mixture, a to produce consistent quality. Characteristics such as bending, tension, frequency or acceleration of the shaping device and / or the mixture can be included in the regulation or control of the block making machine, which then cause, for example, a change in the vibration frequency or the vibration duration or the pressure with which the block forming machine acting on the mold device. The wireless exchange of measurement and / or control data can eliminate costly and annoying cabling on the block making machine or the forming device. The arrangement of a sensor in the molding device makes it possible to attach the sensor protected and unmistakably assigned to a particular mold device. Furthermore, in such housing of the sensor, a mold change is not undesirably complicated. According to a particular embodiment, the invention provides for the sensor to be arranged on the block forming machine separately from the forming device, wherein the sensor performs a non-contact measurement of the observed characteristic of the forming device. With a device of this kind, it is possible to control the block forming machine based on characteristics of the shaping device even when conventional shaping devices are used. Depending on the number of mold devices used, it is therefore only necessary to retrofit a sensor per block forming machine.

Finally, the invention provides for the use of the device also in vehicles, in particular to monitor the life of safety-related components and / or to document their loads. Since safety-relevant components are often subject to vibration loads and a wiring of safety-related components is also often associated with great difficulties, allows Device according to the invention here an uncomplicated and easy to retrofit control option. The spectrum of possible reactions to the evaluation of the measured values ranges from the control of a warning lamp to the controlling intervention in machine components, such as the control engineering avoidance of load peaks. According to the invention, at least two sensors are used on different components in order to be able to reliably diagnose incorrect measurements or total failures.
