摘要： A communication system capable of shortening a setting time of an ID and reducing an incorrect setting is provided. A master device (2), when receiving an ID assignment request from a writing device (4), turns on all a plurality of semiconductor relays (CH21 to CH2n), and after a predetermined time has elapsed, turns all off, sequentially turns on the semiconductor relays (CH21 to CH2n) and each time turning on the semiconductor relays (CH21 to CH2n), sends the corresponding ID. The plurality of slave devices (301 to 30n), when receiving the ID assignment request from the writing device (4) after supplying power, stores the fact in the ID request area (A33), waits for a reception of the ID from the master device (2) without confirming reception of the ID assignment request, and sets the ID as its own ID if determining that the ID assignment request has already been received by the ID request area (A33) after power is supplied.

摘要： Two semiconductor switches (Q1, Q2) are arranged in parallel in a load circuit for connecting a power source with a load. Further, the semiconductor switches (Q1, Q2) are controlled so as to be alternately tuned on and off. As a result, since a current flows through only either of the semiconductor switches (Q1, Q2), an offset error detected by current sensors (12, 22) includes only an offset error of either of the semiconductor switches, the detection of current with high accuracy can be accomplished. Therefore, when performing the control of shutting off the circuit to cope with the occurrence of an overcurrent flowing through the load, the shutoff control with high accuracy can be accomplished.

摘要： A protection apparatus of a load circuit sets a threshold temperature at a lower temperature than an allowed temperature of an electric wire for use in the load circuit, and estimates a temperature of the electric wire based on an ambient temperature, a load current and a time while the load current is flowing through the electric wire. Then, in the case where the estimated temperature has reached the threshold temperature, a semiconductor relay (S1) is broken. As a result, in the case where such an electric wire temperature has risen owing to an occurrence of an overcurrent, and the like, the circuit is surely protected at the point of time before the electric wire temperature reaches the allowed temperature. Therefore, a fuse used in a conventional load circuit becomes unnecessary.

摘要： An electric power distribution device sets a first threshold and a second threshold for a threshold temperature of main wires, and sets a third threshold and a fourth threshold for a threshold temperature of branch wires. In the case where a temperature of each of the main wires reaches the first threshold, all of branch wire switches provided in a branch wire distributor are shut off. Thereafter, in the case where the temperature of the main wire reaches the second threshold, each of the main wire switches, which is provided a main wire distributor, is shut off. In the case where a temperature of a certain branch wire reaches the third threshold, the corresponding branch wire switch is subjected to PWM control. Thereafter, in the case where the temperature of the branch wire reaches the fourth threshold, the corresponding branch wire switch is shut off.

摘要： A vehicular power source controller (1) is designed so that when there is abnormal action in a microprocessor (11) and an abnormal fuse state cannot be determined from the current of a load (5) detected by a current sensor circuit (15), power supply to the load (5) cannot be turned on and off by the operation of a combination switch (3) corresponding to the load (5), but can be turned on and off by the operation of an ignition switch (7). It is thereby possible to prevent continuing power supply to the load (5) when the combination switch (3) is turned on during the abnormal action of the microprocessor (11), and battery exhaustion can be suppressed. Power supply to the load (5) cannot be turned on and off by the operation of the combination switch (3) during the abnormal action of the microprocessor (11), and an operator is easily made aware of the abnormal action of the microprocessor (11).
