    摘要: In a method of monitoring an output module to which a number of inductive loads are connected and in which the current flowing through these inductive loads is regulated by clocked driving of the output stages, the current created in the blocked phases of the output stages by the inductively stored energy is partially or temporarily conducted across a common current measuring device and evaluated for testing the output stages, including the inductive loads.

    摘要: To evaluate the output signal of an active sensor which is configured as a binary current signal, a circuit arrangement is disclosed by which a proportional current is produced from the sensor current by way of a current mirror circuit. The current produced by a current mirroring operation is drawn from a stabilized voltage source by way of an ohmic resistance, and a binary voltage signal corresponding to the sensor output signal is generated thereby. The voltage signal is sent to a flipflop which compares the voltage signal with a reference value that is composed of a reference voltage and a hysteresis voltage. The change-over threshold of the flipflop is varied or adapted as a function of the actual sensor current, leakage currents, etc.

    摘要: To transmit data which is supplied by a rotational speed sensor in the form of an alternating signal as well as additional data via a signal line, a sequence of current pulses of a predetermined duration is derived from the alternating signal, the pulse intervals or interpulse periods containing the information on rotational speed. The additional data is transmitted in the interpulse periods, and transmission of the additional data is synchronized by the individual rotating signal sensor pulses. Preferably, the method is employed for active sensors, and both the sensor pulses and the additional data are transmitted in the form of current signals. During standstill, in the absence of a sensor pulse, transmission of the additional data is triggered by auxiliary synchronization pulses.

    摘要: To monitor a data processing circuit which includes two (or a plurality of) microprocessors or other data processing systems which are mounted on a joint chip and connected by data lines, the microprocessors jointly produce data words which form a data word sequence and are transmitted to a monitoring circuit at predetermined times. The monitoring circuit is arranged on a separate chip. The data words of the data word sequence are checked by the monitoring circuit with respect to the contents and time of appearance of the individual data words. It is favorable to make up the individual data words of partwords which are produced according to different algorithms.

    摘要: A circuit arrangement for monitoring leakage currents of a circuit which includes a plurality of valve coils connected in parallel to a supply line and adapted to be connected to ground by way of individual switches, and wherein the supply line is connected by way of a main switch to the positive pole of the supply voltage source and, further, to a testing current source used as a test signal source, is designed such that prior to each closing of the main switch, with the individual switches still open, the testing current source is connected to the supply voltage source and thereby activated. The result is an increase of the voltage potential on the supply line. A comparator establishes the difference between the potentials on the supply line and the supply voltage. If the difference exceeds a threshold value, this indicates leakage current.
