摘要： PURPOSE:To improve measurement precision and stability and improve a monitoring function, and to reduce the cost of cables, by measuring a radiation level digitally at a radiation measuring terminal station and transmitting the measurement result to a central monitor station in the form of a digital signal. CONSTITUTION:A dose in a radiation atmosphere is detected by a radiation detector 1 at the radiation measuring terminal station 31 and detection pulse are measured by a processing part 33 for a specific time to send the result to a processor 32. The processor 32 converts the counted value into a dose rate, which is stored in a memory 36. A transmission control part 35 sends an up-to- date dose rate to the central monitor station 41, which stores the input value in a memory 57 and displays and records it; and a processor 56 calculates an integral dose in every radiation atmosphere and an average value of the dose rate within a specific time.

摘要： PURPOSE:To efficiently attain offering service of information independently of number of computers at a terminal equipment requesting the information by allowing a node to select optionally plural data sent from a master so as to obtain the required information. CONSTITUTION:A host computer 9 storing the information required by a terminal computer 9 sends cyclically a data frame, that is, the information group of the data frame comprising a flag 11 representing the start of data, an IN-No. part 16 representing the ID-No. of the information part, the information part 14, a CRC part 15 checking the reliability of data and a flag part 11 representing the end of data to a network. The terminal computer 9 requiring information gives a command of ID-No.16 of the required information to a node 2, the node 2 receiving a request receives a data frame coincident with the ID-No.16 from the network and transfers the received information part 14 to the request terminal computer. Thus, the equal service is attained independently of number of sets of terminal computers.

摘要： PURPOSE:To reduce the cost of cable laying and to improve flexibility, by carrying out the periodic fetch of a dosage rate, multiplex transmission, and statistical processing of data through the operations of processors provided to a dosage meter terminal station and a central control station. CONSTITUTION:Outputs pulses 7 from a detector 1 at the dosage meter terminal station 23 are sent to a logarithmic dose rate meter 10, whose output dosage rate signal 40 is sent to an analog signal processing part 22. The processing part 22 stores dosage rate data in the form of a digital signal in a memory 18. A transmission control part 19 sends an interruption signal to a processor 20 at a request from the central control station 31 and an up-to-date dosage rate is sent to the station 31. The station 31 stores the dosage rate value in a memory 25 and performs display and recording and a processor 26 calculates integral dosage in each radiation atmosphere to average the dosage within a specific period.

摘要： PURPOSE:To transmit/receive data with excellent transmission efficiency by allowing a sender computer to send the next data to a node of its own station while the data are sent from a receiver node to a receiver computer. CONSTITUTION:A multi-packet data (n) sent from the sender computer 9 are sent to the receiver node 10 via its own station node 10. The reception side node sends a reply confirmation packet (BACK) on a network 1 to the sender node and then sends the data (n) to the receiver computer 9. The sender node receiving the BACK reply sends a reply confirming packet (ACK) to the sender computer. The sender computer receiving the ACK sends the next data (n+1) to its own station node. When the sender node receives a reponse from the receiver node, the BACK response on the network is sent to the receiver node and then sends the data (n+1) to the receiver node. According to the system, the next transmission data are given in the node to improve the transmission efficiency.
