弊害を招く。If the conditions are not good, it will have to be installed at an unfavorable site. In this case, since some plants have locations where the environmental conditions (temperature, humidity, noise, radiation dose, etc.) are extremely poor, leaving slave stations in such locations will cause various problems.

かかるシステムを採用する場合、次のような要求を満た
さねばならない。As a means of solving this problem, an extension transmission system with excellent environmental resistance is connected to the lower stage of the slave station 2 in parallel with p Ilo, and the slave station of the extension transmission system is installed in a place with poor environmental conditions. A system that does this is conceivable. However, when adopting such a system, the following requirements must be met.

必喪があるため上記機能を欠如させることはできない事
情にある。■First of all, transmission errors are likely to occur in extended transmission systems installed in locations with poor environmental conditions, so error processing can quickly and accurately detect such errors, eliminate erroneous data, and facilitate early recovery. It is necessary to have functions. 4
! However, in the case of Atomic Casilant, the above function cannot be omitted because it is essential to prevent accidents from occurring.

送系をＰＩｌｏとみなしてランダムにアクセスしてくる
。In a normal multiplex transmission system on the 0th order, only the PIloJ is connected to the slave station 2, so access to the PIloJ is random access and can be freely performed. Therefore, when directly linking the extension transmission system to the above multiplex transmission system, if the extension transmission system is directly replaced with the previous PIlo, the multiplex transmission slave station 2 regards the extension transmission system as PIlo and randomly accesses it. come.

機能を延長伝送系にもたせない以上、多重伝送親局１お
よび子局２のハードウェアの変更を要することになる。Since the extension transmission system cannot be equipped with a function that can reliably accept the random access described above, it is necessary to change the hardware of the multiplex transmission master station 1 and the slave stations 2.

ることはできない。■Furthermore, since the extension transmission system will be installed in a location with the worst ground environmental conditions and is only meant to serve as an auxiliary device, it must be as conductive as possible. In particular, in the field for monitoring and controlling an atomic coupler, there are often only ``restricted and narrow spaces,'' so the connoisseur nature of the extended transmission system cannot be ignored.

提供することにある。The present invention has been made in consideration of these circumstances, and its purpose is to provide a master station for an extended transmission system to the slave stations without making any changes to the hardware of the master station and slave stations for the multiplex transmission system. In addition to being able to connect directly, even if a transmission error occurs due to noise etc., it is possible to quickly return to the normal state.One station and slave stations of an extension transmission system can be formed compactly even when no microtransmission system is used. It is an object of the present invention to provide a data transmission device for monitoring and controlling an atomic humidifier, which is highly preferable when the above-mentioned extension transmission system is installed in a narrow space with poor environmental conditions.

The register 6.1, the serial transmission/transmission/reception unit 8, the control circuit 9, the interface 10, and the register 6.7, the serial transmission/transmission/reception unit 8 are connected in series to the multiplex transmission slave station 2 via the data/4 bus. These are connected to the control circuit 9 and controlled by the control circuit 9. Note that the interface 1o is used only when PIlo is coupled to the extension transmission slave station 5. The control circuit 9 does not include a microprocessor.

制御回路９からの制御信号によって制御される。Next, the operation of the apparatus configured as described above will be explained. When data is accessed from the multiplex transmission slave station 2 to the extended transmission master station 4, the first register 6 of the extended transmission master station 4 accepts the data regardless of the timing of the access. Above Atsurujista 6
When the reception of the data to the register is completed, the data is transferred from the register 6 to the second register on the condition that the serial transmission/transmission/reception section 8 is not performing a transmission operation. The serial transmission/transmission/reception unit 8 cyclically and serially transmits the contents of the stripe 2 register 7 to the extension transmission slave station 6 at a predetermined time interval. The series of operations described above are controlled by control signals from the control circuit 9.

Therefore, multiplex transmission master station 1 or multiplex transmission slave station 2
The extended transmission master station 4 can be directly coupled to the slave station 2 without any modification of the hardware.

ーによる弊害は生じない。The contents of the second register 1, which do not change, are transmitted cyclically and serially at high speed by the serial transmission/transmission/reception section 8. However, at the atomic cublant site, there is an extremely large amount of noise from motors, generators, interrupters, etc., making it easy for errors to occur in the data. No harm will occur due to transmission errors.

Therefore, the device can be sufficiently miniaturized without using a MOS microprocessor or the like. Therefore,
This makes it possible to avoid the use of MOS products that are easily affected by radiation, and at the same time to make the device more compact.

用データ伝送装置を提供する。Therefore, according to the present invention, since input data can be accepted into the first register at any time, the extended transmission system can respond to random access from the multiplex transmission system. As a result, the master station of the extended transmission system can be directly connected to the slave station without changing the hardware of the master station and slave stations of the multiplex transmission system. Furthermore, according to the present invention, the contents of I! do not change until the data filling into the first register is completed.
Since the contents of the second register are transmitted cyclically and serially, even if a transmission error occurs due to noise or the like, it is possible to quickly return to the normal state. Furthermore, according to the present invention, the required functions can be achieved by the combination of the 18th and 2nd registers, so even when a microprocessor or the like is not used, the master station and slave station of the extension transmission system can be made compact, allowing the above-mentioned functions to be carried out in a narrow space. It is very suitable as a device for installing an extension transmission system. Accordingly, according to the present invention, the s
