Abstract
A device for testing and adjusting ripple control receivers by means of audio-frequency test telegrams and digital signals in which both types of signal and the power supply of the ripple control receiver (1) are provided via one and the same signal terminal (2) of the ripple control receiver (1). Mutual interference between the signals of different kinds is prevented by their differing signal levels.
Description
Arrangement for testing and adjustment of ripple-control receivers The invention concerns an arrangement for the testing and adjustment of ripple-control receivers by means of audio frequency test messages and by means of digital data input and output, in which the ripple-control receiver is provided with a common signal connection both for the input of test messages as well as for the input and output of digital signals.
As is known, ripple-control receivers serve to carry out control commands which in the form of audio frequency messages are superimposed on the mains a.c. voltage, for example for switching on and off electrical heating systems by remote control. Each ripple-control receiver in this case has a separate command adjustment which has to be initially set, checked occasionally and if necessary altered. Hitherto this was done by using either mechanical adjusting members or plug-in electronic memory components (PROM, EEPROM). However, it is also known to provide the necessary data to the adjusting members by means of a multi-polar plug-in connection to a programming apparatus. The correct reaction of ripple-control receivers to audio frequency messages is tested by means of test messages, wherein the audio frequency voltage is supplied either via the connected multi-polar programming apparatus or via an additional terminal clamp. In order to verify the correct function, it has been known in this connection to feed an audio frequency test message via an internal contact from a pocket transmitter to the ripple-control receiver.
The state of the art is represented by two specifications: The PCT-WO 89/12345 concerns a remote-controlled monitoring device for a distribution system in which through remotecontrolled manipulation by mans of a diagnostic apparatus, different conditions can be simulated and their correctness is checked by the remote control monitoring, in which a separate channel is provided for the data transmission. This channel is used exclusively for digital information.
In the DE-OS 30 31 163 is described a control device for ripple-control receivers with a variable output member (e.g. for the phase control of a load), in this specification there is no mention about the adjustment or testing of the ripple-control receiver.
It is the object of the invention to provide a common signal connection both for the input of test messages as well as for the input and output of digital signals and thereby to prevent interferences by signals of various kinds.
The arrangement permitting this is characterised in that the values of the voltages which represent the test messages on the one hand and the digital signals on the other hand have widely varying signal levels, in which mutual interferences in the devices responsive to these different voltages are cut off by increased response threshold values or by protective diodes. This allows not only all the analogue and digital voltages to be supplied via a common signal terminal clamp, but this also provides the constructional advantage of being able to arrange in the same terminal region the common signal terminal clamp together with the remaining terminal clamps of the ripplecontrol receiver.
According to further features of the invention, for differentiating between digital signals and audio frequency signals it is advantageous either to superimpose on the audio frequency signal a d.c. signal voltage or to keep the signal level of the audio frequency signals below the operating point of the devices responsive to the digital signals.
An embodiment example of the invention is shown in the drawing. The circuit components belonging to the ripplecontrol receiver 1 are delimited by the broken lines. The signal connection serving both for receiving the test messages as well as also the digital signals is designated the numeral 2. For the purpose of testing and adjusting the ripple-control receiver 1, through a test terminal 4 a test apparatus 3 can be connected to the signal connection 2, which apparatus separately contains an audio frequency transmitter 5, a data receiver 6 and a data transmitter 7 which are both provided for the receipt or delivery of digital signals. These apparatus as well as connected apparatus in the ripple-control receiver 1 are supplied by a d.c. voltage source 8 with a series-connected current limiter 9 which protects the d.c. voltage source 8 against short-circuiting.
Situated within the ripple-control receiver 1 and connected via a high resistance 10 to the signal connection 2 is an audio frequency filter 11 (bandpass filter) to which a low resistance 12 is connected in parallel. The digital signals are processed by a microcomputer 13 containing inter alia a data receiver 14 and a data transmitter 15.
Numeral 16 designates the mains voltage input connected for example to the phase R, the opposite pole being the directly earthed conductor 17. From the main voltage input 16 during normal operation the ripple-control signals via a high resistance 18 reach the input of the audio frequency filter 11 to which are connected the other devices for evaluating the ripple control signals (not shown in the drawing). To the mains voltage input 16 is furthermore connected a power supply unit 19 for supplying the voltage to the control elements operating at low voltage, the output d.c. voltage of the power supply unit 19 being stabilised by means of a charging capacitor 20. The output of the power supply unit 19 is protected from the signal connection 2 by means of a diode 21 which discharges excess voltages. The microcomputer 13 requires a particularly well stabilised supply voltage which is supplied by a voltage regulator 22 connected to the output of the power supply unit 19. The supply voltage input 23 of the microcomputer 13 is protected from the data input 24 of the data receiver 14 by means of a voltage-limiting diode 25. A series resistance 26 between the signal connection 2 and the data input 24 limits the signal level of the data receiver 14. Numeral 27 designates an electronic switch which is controlled by the data transmitter 15 of the microcomputer 13 and in the switched-through condition short-circuits the signal connection 2 (signal feed-in point) to earth.
In the normal operating condition, the phase connection 16 of the phase R is subjected to the ripple-control signal discharged from the mains which, via resistance 18, reaches filter 11 and through this is evaluated in a manner which is not described in any further detail. The voltage supply to the ripple-control receiver 1 by the power supply unit 19 in this condition is thus ensured.
When the ripple-control receiver 1 is tested, the test apparatus 3 is temporarily connected to the signal connection 2 by means of the test terminal 4. Connected in a conducting manner at the same time also is the base potential of the individual apparatus 5, 6 and 7 located in the test apparatus 3 as well as the d.c. source 8 with the base potential of the circuit elements 11, 12, 14, 15, 17, 19, 20, 22 and 27 located in the ripple-control receiver 1. During the testing, the ripple-control receiver 1 with the phase connection 16 is separated from the phase R. The open-circuit potential of the signal connection 2 even in the switched-off condition of the ripple-control receiver 1 is so high that via diode 21 and the charging capacitor 20 this can provide the entire voltage supply to the ripple-control receiver 1. In a testing process the sensitivity of the filter 11 is tested with the aid of the audio frequency transmitter 5 located in the test apparatus 3 .
The reactions of the ripple-control receiver 1 to the digital data transmissions of the audio frequency transmitter 5 are produced by the data transmitter 15, located in the microcomputer 13, which by means of the electronic switch 27 according to a given program code, with the timing of the digital signals provided for this, reduces the signal voltage at the signal connection 2 by producing a discharge to the base potential. This reduction in voltage at the signal connection 2, occurring in pulses, is recognised by signal receivers 6 located in the test apparatus 3 and evaluated in a respective manner.
In a similar manner takes place the data input from the test apparatus 3 to the microcomputer 13 of the ripplecontrol receiver 1 with the aid of contact closures in the signal transmitter 7, in which the voltage is similarly reduced at the signal connection 2. These voltage reductions are recognised and evaluated by the signal receiver 14.
The separation, which is necessary for the smooth operation of all devices, between analogue signals (audio frequency signals) and digital signals during the recognition by the different receivers can be achieved on the one hand in that the voltage amplitudes of the audio frequency signals are substantially smaller (e.g. 2 V) than the voltage of the digital signals (e.g. 5 V), whereby the response threshold of the digital signal receiver is correspondingly raised. On the other hand, the analogue signal voltage also can receive a high d.c. voltage level and the receivers for the digital signals are therefore provided with protective diodes.
