摘要： PROBLEM TO BE SOLVED: To avoid inconvenience of manual avoidance operations and useless power consumption till the avoidance is finished by operating a 1st operating mode control section when correction of synchronization is failed for a predetermined time or number of times or over. SOLUTION: After start signal detection means 11, 17 of radio communication means A, B detect a manual start signal resulting from a switch or the like, 2nd operating mode control sections 7, 13 are operated to set the radio communication means A, B to be in the 2nd operating mode thereby conducting initial synchronization matching for the intermittent communication between them. When initial synchronization matching is finished, 3rd operating mode control sections 8, 13 are operated and synchronization is corrected intermittently for each predetermined time for the communication. However, where correction of synchronization is failed for a predetermined time or number of times or over, central control sections 9, 15 activate 1st operating mode control sections 6, 12 to stop the operation of radio communication sections 10, 16 thereby restoring the mode automatically to a sleep mode awaiting the detection of a start signal, than the communication is tried again without a special restoration operation.

摘要： PROBLEM TO BE SOLVED: To sense a carrier at short intervals exerting no influence on a communication time within the communication time by shortening the carrier sense intervals of a reception side under the control of a timer means and also shortening the transmit signal of a transmission side correspondingly. SOLUTION: In a communication state, a control means 3 actuates a power source control means 4 by set values of the set timer means 5 to supply electric power to radio equipment 2. The carrier sense function of the radio equipment 2 judges whether or not a radio wave is received by an antenna 1 in a short time. When no radio wave is received, the control means 3 stops supplying the electric power to the radio equipment 2 and when the radio wave is received, the power supply is maintained. For transmission, on the other hand, a link connection signal is sent from the antenna 1 in response to the start of the power supply to the radio equipment 2 from a standby state. The timer means 5 actuates a power source control means 4 to supply the electric power to the radio equipment 2.

摘要： PURPOSE: To attain a wireless system for an automatic metering system without revision of a specification of each equipment in an existing automatic metering system utilizing radio communication. CONSTITUTION: A 're-transmission request text' is stored in a dummy text storage means A6. A timer A5 starts measurement when a text transmission reception means A3 receives a text and finishes the measurement when a radio signal transmission reception means A4 receives the text. If the timer time is almost up before the text transmission reception means A3 receives the text from the radio signal transmission reception means A4, the timer A5 informs it to the dummy text storage means A6. Upon the receipt of a signal from the timer A5, the dummy text storage means A6 sends the 're-transmission request text' stored therein to a microcomputer meter. On the other head, a radio communication means B13 at a terminal equipment side is operated similarly.

摘要： PROBLEM TO BE SOLVED: To conduct bit synchronizing processing with high accuracy corresponding to a state of a radio channel and a change in a communication protocol by means of the software. SOLUTION: The receiver is provided with an arithmetic means 1 that calculates an edge mean error and an edge error maximum value based on an edge detection signal, an arithmetic time value and a sampling clock signal 191 and provides an output of the result as a calculated value and with a storage means 16 that stores a permissible range of the edge mean error and a maximum value of the edge error, and also with a comparison means 15 that reads the permissible range of the edge mean error and the maximum value of the edge error, compares them with the calculated values and provides an output of an error signal when the comparison indicates the calculated values to be at the outside of the specified range and provides an output of a synchronization establishment signal when the comparison indicates the calculated values to be at within the specified range. Thus, bit synchronization processing with high accuracy is conducted by the software processing.

摘要： PROBLEM TO BE SOLVED: To analyze how the system has been affected from a surrounding environment when there is any defect in the communication. SOLUTION: A transmitter 3 is composed of a transmitter side clock means 7 measuring a transmission time and a transmitter side recording means 8. Since the transmitter side recording means 8 records the transmission time and the transmission content, when a 1st device 1 is defective, whether or not the transmitter 3 has made normal transmission is analyzed. Furthermore, a receiver 9 is composed of a receiver side clock means 14 measuring a reception time and a receiver side recording means 15. Since the receiver side recording means 15 records the reception time and the reception content, when a 2nd device 10 is defective, whether or not the receiver 9 has made normal reception is analyzed.

CONSTITUTION:The horizontal direction is defined as x-direction, the direction of the axis of revolution of a rotating means 1 as z-direction, and the direction of the side surface as y-direction respectively. In a first sensor means 3, a sensor senses the magnetism by the line of the magnetic force which is generated by a magnetic body 2 and parallel to the axis of revolution, and the high output signal is outputted thereby, and at the same time, the magnetism sensing surface is arranged in the y-z plane so that the low output signal may be outputted by the component in the y-direction of the line of the magnetic force to be generated by the magnetic body 2. A second sensor means 4 is rotated by 135 deg. relative to the means 3, and the magnetism sensing surface is arranged in the y-z plane at the position of about 5mm apart from the center of the axis of revolution, and a sensor detects the line of the magnetic force which is generated by the magnetic body 2 and parallel to the axis of revolution and the magnetic field of the y-direction component of the magnetic field, and outputs the signal. This constitution provides the required intensity of the magnetic field, and downsizes the magnetic body 2.
