Description

The invention relates to a method and a device for testing and evaluating a Individual steps in the form of pulses and pulse pauses in existing pulse patterns in ripple control receivers, which have a storage device for a pulse group assigned to them, and which is half a facility for step-by-step comparison of the received pulse message can be controlled separately with the respective stored ImpulsbUd.

Such a method with the associated device for carrying it out is already known (CH-PS 430 838).

The facts described below are also known:

In ripple control technology, a control command is sent to one or more receivers by means of preferably audio-frequency pulses which are superimposed on a power network . Such a control command can, for example, cause a switching to be switched off or to be switched over in the receiver. Br can, however, also mean the retention of an already existing switching state * Since the tone-frequency pulses used, for example, to transmit the control command in ripple control technology are as a whole

Electricity consumers, for example hot water spouting pulses, form more commands (cf. Swiss more, to switch them on or off temporarily. Others smell patent specification 325 985).

For example, there are -10 elements for η depending on the selected class m of the combination, the following numerical values:

A ripple control system according to the Swiss patent specification 430 838 has the advantages of a high command * compared to other known systems count for a given number of sub-intervals and high immunity to interference.

It should be noted, however, that in this system, when the encoder device is running only one command was sent at a time.

Since hi power networks, for example in the event of a breakdown, as many electricity consumers as possible, for example all hot water storage tanks, are possible quickly should be switched off, the fact mentioned has a very disadvantageous effect, because it is necessary to switch off of all hot water storage tanks as many processes of the transmitter device - and a corresponding amount of time - are necessary as one has provided individually switchable boiler groups Several individually switched on and boiler groups that can be switched off are, however, in order to achieve a uniform load curve of the Power network is indispensable.

If you use the ripple control system to transmit alarms, for example fire alarms, you will normally use the one used for extinguishing * Divide the firefighters to be deployed into groups.

This grouping can for example take place according to regional aspects and / or according to the aspect of the danger of fire traps. Depending on the location and the danger of the fire, you become one or more fire brigade groups provide through appropriate individual ripple control commands. There is at least a very difficult one If there is an urgent need to call all fire brigade groups as quickly as possible, i.e. with one expiry of the Alerting device. However, this is the case with devices according to the Swiss patent specification 430838 not possible.

Similar relationships exist if ripple control systems are used for the purpose of air raid alarms or for controlling street lights with dilution possible

Even in these cases, facilities according to Swiss patent specification 430 838 are unsatisfactory full, because the general alarm or blackout cannot be implemented quickly enough.

Based on the state of the art as described above It is the object of the invention to improve the aforementioned method so that it is possible to use a Specifiable number of separately controllable groups of ripple control receivers, if necessary to be addressed at the same time. This object is achieved according to the invention in that the comparison of the received with the stored Impulse pattern is omitted during at least one single step

With this surprisingly simple measure 4 ', individual recipient groups can advantageously be called both separately and together so that all practical requirements are taken into account.

An exemplary embodiment of the invention is explained in more detail below with reference to the drawings

This is no longer the case with the method described, which is a decisive technical step forward.

With reference to Fig. 1, which pulse patterns of various commands for the method described represents, a relatively simple example with five sub-intervals will now be explained pointed out that it is not limited to this small number of five sub-intervals, rather Can it be used for any number of sub-intervals. Also the ta Fig. I continues The commands shown only represent cases that can be easily surveyed.

Use in the pulse pattern example according to FIG Ripple control transmitter and ripple control receiver Pulse patterns with five sub-intervals after the start pulse. Each time the transmitter device runs, the start pulse is followed by five sub-intervals, which are available as elements of the combination for the formation of impulse patterns.

If you use class 3 combinations of five elements for a command, the result is total
