Description

  The present invention relates to an industrial information processing apparatus having an extended function according to customer specifications.

  The conventional industrial information processing apparatus (PC) is constructed by selecting and combining a main board on which a CPU is mounted and an I / F expansion board on which a function required by a customer is mounted. This I / F expansion board requires a riser board and a backplane board that are bus expansion boards for connecting the I / F expansion board by being connected via the ISA bus, PCI bus, and PCI EXPRESS ( For example, see Patent Document 1), otherwise, a space is required so that the I / F expansion board can be directly connected to the main board on which the CPU is mounted.

Conventionally, an industrial information processing apparatus in which a CPU board and an I / F expansion board are arranged vertically and connected via a connector is known. Further, for example, Patent Document 2 discloses a technique for miniaturizing, thinning, high-density mounting, and speeding up an industrial information processing apparatus by stacking substrates vertically.
JP 2004-327588 A Japanese Patent Laid-Open No. 08-23149

  However, in a conventional industrial information processing apparatus, when a riser board or a backplane board which is a bus expansion board is used, there are a disadvantage that a space is increased and a cost is increased. For this reason, when space is taken into consideration, it is most efficient to customize a board that has all the necessary functions on a single board, but when listening to customer requests and designing as a single board However, since the specifications required for each customer are different, there is a problem in that it takes time and effort to design and verify, and requires a lot of development costs. In particular, verify whether the CE test and the VCCI test are satisfied, that is, conduct a leaked radio wave test and a conduction noise test to test whether the regulation value is satisfied. There is a problem that it takes time and cost to perform the verification and satisfy the regulation value. Furthermore, when designing as a single board, the number of wiring pattern layers on the board body (raw board) is designed according to the number of wiring pattern layers required on the CPU board, but it is a circuit that realizes an extended function. The number of wiring pattern layers required is not necessarily the number of wiring pattern layers actually required for the CPU substrate. However, the circuit that realizes the extended function has to be the same as the number of wiring pattern layers necessary for the CPU board, and the cost of the board itself is increased.

  In addition, in the configuration in which the boards are arranged on the top and bottom, the extension board faces the CPU board. Therefore, there is a high possibility that the extension board malfunctions due to leakage radio waves (radiated noise) and induction noise generated from the CPU board. In addition, the heat generated from these substrates interacts with each other, and when stored in the housing, the generated heat raises the temperature inside the housing, exceeds the allowable temperature of the substrate, and may not operate.

On the extended custom board 22, devices / parts and ports that are designed according to customer's extended specifications and realize an extended function are arranged, and the extended specifications are realized by a single board.

  Further, on the extension custom board 22, near the connector 23, the parallel signal of the extension custom board 22 is converted into a serial signal based on the interface standard and transmitted to the CPU base board 21 and received from the CPU base board 21. A bridge IC 41 for converting the serial signal thus converted into a parallel signal is provided.

3. Expansion of D-Sub connector for direct connection of D-Sub connector cable without conversion from USB.
4). Additional graphic controller (VGA) that enables multi-channel image output.
5. Additional analog I / O points and digital I / O points.

  The expansion custom board 22 is not limited by the number of wiring pattern layers of the CPU base board 21 each time according to the customer's expansion specifications, and the wiring pattern of the board body (substrate) is designed so that the wiring pattern of the substrate The layers are determined, the board is manufactured, the equipment / parts are mounted, and the operation is inspected with the extended custom board 22 alone.

After that, it is mounted on the housing 11 and connected to the CPU base board 21 of the common specification by the connector 23.
As described above, the application program of the CF card 38 is changed depending on the contents of the extended function.

  The serial port 42 and the D-Sub connector disposed on the extension custom board 22 are protruded from the side surface 11b or the rear surface 11d opposite to the front surface 11a, and the thin side portion (front surface 11a) of the housing 11 is projected. External connectors for connecting to external devices are arranged on both side surfaces 11b and back surface 11d). The external connectors are the line output connector 30, the USB port connector 31, the display connector 32, the LAN connector 33, the first serial port 34, the second serial port 36, the serial port 42, the D-Sub connector, and the like.

With the above configuration, the industrial information processing apparatus 10 is manufactured by the following procedure.
First, when the customer's extension specification is sent from the customer, the extension custom board 22 is designed and manufactured as described above, and in parallel with the design and manufacture of the extension custom board 22, the extension function and the drive to be connected are connected. Accordingly, a program for the CPU 20 is produced and written to the CF card 38.

  When the expansion custom board 22 is manufactured, the inspection is executed. When the expansion custom board 22 is completed, the stocked CPU base board 21 is first mounted on the stocked chassis 11, and then the ferrite 23 is sandwiched between the top and bottom of the connector 23. 25 is attached, the expansion custom board 22 is mounted, and the connector 23 is connected to the CPU base board 21 of the common specification.

Subsequently, the sheet metal 24 is attached so as to separate the CPU base board 21 and the extension custom board 22.
Subsequently, the CF card 38 that is energized and in which the program is written is attached to the CF card slot 35 of the CPU base board 21, and the OS and application programs are executed.

After the operation inspection, the product is shipped to the customer.
As described above, according to the present embodiment, transmission / reception of data between the CPU base board 21 and the extended custom board 22 is executed based on a preset interface standard. Even if the expansion function of the expansion custom board 22 changes depending on the customer's expansion specifications, data can be transmitted and received, and the CPU base board 21 can be supported with the common specifications. Therefore, it is not necessary to design a circuit around the CPU for each customer, and it can be mass-produced and stocked in advance as a verified board for noise testing, thereby greatly reducing the time for designing and verifying the apparatus. Further, in this way, by using the CPU base board 21 without designing the circuit around the CPU, it is only necessary to design the expansion custom board 22 based on the customer's expansion specifications, and therefore the estimation of the apparatus becomes easy. Prompt response for sales is possible. Further, since the extended custom board 22 is a separate board from the CPU base board 21, it is possible to utilize the resources so far, to easily design the wiring pattern, and to shorten the design time (CPU base If the board 21 and the extension custom board 22 are the same board, the number of wiring pattern layers on the board of the extension section must be the same as that of the CPU section, making it difficult to utilize the existing resources.

  In addition, according to the present embodiment, the CPU base board 21 and the extension custom board 22 are arranged adjacent to each other in a plan view, so that leakage radio waves (radiated noise) and induction noise generated in the CPU base board 21 are reduced. 22 is less likely to be affected. As shown in FIG. 3, the CPU base board 21 and the extension custom board 22 are arranged adjacent to each other when the CPU base board 21 and the extension custom board 22 are vertically opposed to each other. The inductance can be reduced, and the influence of electromagnetic induction noise can be reduced. In FIG. 3, the wiring pattern of the CPU base board 21 is represented by the coil 1 on the outer periphery of the board, the wiring pattern of the extended custom board 22 is represented by the coil 2 on the outer periphery of the board, and in the model 1, the coil 1 and the coil 2 are separated by a distance d. In the model 2, the coil 1 and the coil 2 are arranged at a distance d (mm) in a plane. Then, by passing a constant current through the coil 1 and changing the distance d (mm) and measuring the electromotive force e of the coil 2, the mutual inductance M accompanying the change of the distance d (mm) is measured. The lengths of the coil 1 and the coil 2 are matched to the outer peripheral dimensions of the boards 21 and 22 (width a = 125 mm, length b = 180 mm). As can be seen from the characteristic diagram of the inter-substrate distance d and the mutual inductance M in FIG. 3B, the model 2 in which the coil 1 and the coil 2 are arranged in a plane is compared with the model 1 in which the coil 1 and the coil 2 are vertically opposed. Thus, it can be seen that when the mutual inductance M is small and the CPU base board 21 is operating, the extended custom board 22 is not easily affected by the mutual inductance M, and therefore is not easily affected by electromagnetic induction noise. Similarly, since the distance between the CPU base board 21 and the extension custom board 22 can be increased, the electrostatic capacity between the CPU base board 21 and the extension custom board 22 can be reduced, and electrostatic induction noise can be reduced. In addition, leakage radio waves (radiated noise) can be reduced.

  Further, when the area X where the CPU base board 21 is arranged and the area Y where the expansion custom board 22 is arranged are spatially separated by the sheet metal 24, leakage radio waves (radiated noise) generated from the CPU base board 21 are It is possible to prevent flying to the expansion custom board 22 through the space in the body 11, and it is possible to prevent leakage radio waves from affecting the expansion custom board 22. Further, the ferrite 25 can prevent conduction noise such as the clock frequency of the CPU 20 generated from the CPU base board 21 from propagating through the connector 23 to the extension custom board 22, and the conduction noise affects the extension custom board 22. Can be prevented.

  As described above, the influence of the leakage radio wave and conduction noise generated in the CPU base board 21 on the extended custom board 22 can be prevented, so that the extended custom designed each time according to the customer's extended specifications. The board 22 can be easily verified against noise, and the design / verification time and cost of the extended custom board 22 can be reduced.

  Further, according to the present embodiment, by arranging the CPU base board 21 and the extension custom board 22 adjacent to each other in plan view, it is possible to reduce the possibility of mutual heat generation affecting the other, and the substantially upper surface of the housing 11. By using the entire 11c as the heat radiating fins 12, it is possible to improve the efficiency of heat radiation, thereby eliminating the need for forced cooling, eliminating the need for a cooling fan, and improving the reliability of the apparatus. In addition, by arranging the CPU base board 21 and the extension custom board 22 adjacent to each other in plan view, it becomes easy to estimate the amount of heat generated in the housing 11, and thus the design of the housing 11 (including the heat radiation fins 12) can be made. When the shape of the standard housing 11 is determined, the amount of heat generated from the expansion custom board 22 designed for each customer is determined, and the circuit design for the heat generation of the expansion custom board 22 is easy. It becomes.

  Further, according to the present embodiment, by arranging the CPU base board 21 and the extension custom board 22 adjacent to each other in plan view, the design of the housing 11 is facilitated, and a useless space is not required. It can be made thin and small, so that the device can be placed and installed in a small space.

  According to the present embodiment, PCI EXPRESS is used as the interface standard, but one or more of general interface standards such as LAN and SATA can be selected and used. For example, when a hard disk and analog I / O are mounted on the expansion custom board 22, PCI EXPRESS and SATA are used.

  Further, according to the present embodiment, the plate-like sheet metal 24 is arranged as the shielding means between the area X where the CPU base board 21 is arranged and the area Y where the extended custom board 22 is arranged. The sheet metal 24 is not limited to a plate shape, and may be a mesh plate shape. At this time, since the area X is not in a sealed state and the generated heat can move to the area Y, measures against heat of the housing 11 can be facilitated.

  Further, according to the present embodiment, the plate-like or net-like plate metal 24 is mounted in the housing 11 after the CPU base board 21 and the extension custom board 22 are mounted. It can also consist of a good heat conductor and can be fixed in advance so as to separate the areas X and Y on the back side of the upper surface 11c of the housing 11. At this time, after the CPU base board 21 and the extension custom board 22 are mounted, when the upper surface 11c of the housing 11 is covered (attached), the areas X and Y are separated by the sheet metal 24, so that the leaked radio wave is CPU base. It is possible to shield the board 21 from flying through the space to the expansion custom board 22, and the sheet metal 24 comes into contact with the heat radiation fins 12 on the upper surface 11 </ b> C. The heat is transferred to the heat radiating fins 12 to be radiated, thereby improving the heat radiation efficiency.

  Further, when the sheet metal 24 is fixed to the back side of the upper surface 11c of the housing 11, a heat conductive sheet for heat dissipation, a noise countermeasure shielding material (gasket), or an electromagnetic wave absorbing ability (excellent electromagnetic wave absorbing ability). The electromagnetic wave absorbing heat conductive sheet {for example, λGEL (trademark) manufactured by Gellac Co., Ltd.} may be used for fixing. By sandwiching the heat conductive sheet between the back side of the top surface 11c of the housing 11 and the sheet metal 24, invisible irregularities and manufacturing errors can be absorbed, and the back side of the top surface 11c and the sheet metal 24 can be brought into close contact with each other. Heat conduction can be improved. Further, by sandwiching a noise countermeasure shield material between the back side of the upper surface 11c of the housing 11 and the sheet metal 24, invisible irregularities and manufacturing errors can be absorbed and the back side of the upper surface 11c and the sheet metal 24 can be brought into close contact with each other. Therefore, it is possible to suppress leakage of radio waves (radiated noise) through an invisible gap between metals. Further, by sandwiching the electromagnetic wave absorbing heat conductive sheet between the back side of the upper surface 11c of the housing 11 and the sheet metal 24, invisible irregularities and manufacturing errors can be absorbed and the back side of the upper surface 11c and the sheet metal 24 can be in close contact. Therefore, heat conduction can be improved and leaked radio waves (radiated noise) can be absorbed.

  Also, a contact made of a good heat conductor that is in direct contact with the heat generating part (IC chip or the like) of the CPU base board 21 and the extension custom board 22 is connected (fixed) to the sheet metal 24. It is also possible to dissipate heat from the heat dissipating fins 12. These contacts can be directly fixed to the back side of the upper surface 11C of the housing 11.
