Description

本発明は、車番認識装置や河川監視装置などの社会インフラ設備用として柱上に設置される制御装置に関する。   The present invention relates to a control device installed on a pillar for use in social infrastructure facilities such as a car number recognition device and a river monitoring device.

屋外の柱上に設置される社会インフラ整備用の制御装置には、路上の車両情報や河川などの水位情報をカメラなどの撮像機器を用いて監視し、撮像機器からの情報を通信したり制御する車番認識装置や監視制御装置がある。   The control device for social infrastructure maintenance installed on an outdoor pillar monitors the vehicle information on the road and the water level information of the river using an imaging device such as a camera, and communicates and controls information from the imaging device. There are vehicle number recognition devices and monitoring control devices.

これらの制御装置は、一般的に屋外の高い場所に設置されるが、既存の柱上に設置される場合が多いので、市内における排気ガス,山間における高温多湿,沿岸の海塩,車両通過による振動,都心における風圧などの過酷な環境に晒されるため、耐環境性が求められる。   These control devices are generally installed in high places outdoors, but are often installed on existing pillars, so exhaust gas in the city, high temperature and humidity in the mountains, coastal sea salt, vehicle passage Because it is exposed to harsh environments such as vibration caused by wind and wind pressure in the city center, environmental resistance is required.

一方、制御装置は、低コスト化が求められる他、柱上に設置する必要があるため、製品の重量制限や外形の寸法制限があり、実装する器具や機器の小型化が求められている。   On the other hand, since the control device is required to be reduced in cost, it is necessary to install the control device on a pillar. Therefore, there is a limit on the weight of the product and a limit on the size of the outer shape, and downsizing of instruments and devices to be mounted is required.

しかし、耐環境性を向上することと低コスト化とは、相反する面があり、一般的には、耐環境性を向上するため市販されている耐環境性の高い材料や部品、及び塗料などを用いるとコストが大幅に高くなり、逆にコストに抑えると筐体の錆や劣化,電気的なショートの発生などにより、装置が停止するトラブルに至る。   However, there is a conflict between improving environmental resistance and reducing costs. Generally, highly environmentally resistant materials and parts that are commercially available to improve environmental resistance, paints, etc. If the cost is used, the cost will be significantly increased, and conversely, if the cost is kept low, the device will be shut down due to rust and deterioration of the housing, electrical short-circuiting, etc.

これらの制御装置の内部実装は、受電部と、制御機器や通信機器,制御機器や通信機器に電源を供給する電源機器,外部機器との信号や電源を送受信するインターフェイス部、及びこれらの機器を保護するためのヒューズやリレーなど、保守するための器具などにより構成されている。   The internal implementation of these control devices consists of a power receiving unit, a control device and communication device, a power supply device that supplies power to the control device and communication device, an interface unit that transmits and receives signals and power to and from external devices, and these devices. It consists of maintenance tools such as fuses and relays for protection.

屋外に設置される一般的な制御装置の内部実装は、電源部と機器を冷却する部,制御や通信機器を実装する部など、複数のユニットで構成されていることが多い。複数のユニットで構成した場合、複数のユニットを複数の作業者が外で組み込み配線できる利点があるが、小型の制御装置では、ユニット内の配線よりユニット間の配線本数が多く、ユニット間の配線ルートを内部筐体の両側面を利用して固定しているため、配線作業者は狭い筐体内で配線を固定したりルートを合わせる必要があり、又、複数のユニットを装置内の背面や両側面など数箇所の面に実装しているので、部材や各ユニットの取付け方向がバラバラのため、作業者は装置内の狭い空間で組立・配線作業しなければならなく、右,左方向に向きを変えたり、移動したり、工具を持ち変えたりムダな作業が増加し、作業性が低下し製作コストが増加するという問題がある。又、部材数が多く、部材が多い程、部材の隙間や部材の端面部が多く、端面部やシャープ部が増えるため、雨水や雪,塵埃などが堆積し易く、材料に塗布する塗料の膜厚も不均一になりやすいため、耐環境性が低下し、且つコストも増加してしまう問題がある。   The internal mounting of a general control device installed outdoors is often composed of a plurality of units, such as a power supply unit and a unit for cooling equipment, and a unit for mounting control and communication equipment. When configured with multiple units, there is the advantage that multiple units can be installed and wired by multiple workers outside. However, in a small control device, the number of wirings between units is greater than the wiring within units, and wiring between units Since the route is fixed using both side surfaces of the internal housing, the wiring operator needs to fix the wiring or align the route in a narrow housing. Since it is mounted on several surfaces such as the surface, the mounting direction of the members and each unit is different, so the operator must assemble and wire in a narrow space in the device, and turn to the right and left Change, move, change tools, wasteful work increases, workability decreases, and production costs increase. Also, as the number of members increases, the more members there are, the more gaps between the members and the end surfaces of the members, and the more the end surfaces and sharp parts increase, so rainwater, snow, dust, etc. are more likely to accumulate, and the coating film applied to the material Since the thickness tends to be non-uniform, there is a problem that the environmental resistance is lowered and the cost is increased.

軽量化を実現するため、〔特許文献1〕には、内部に電気機器を収納する筐体において、左右夫々に板状体の側板を設け、これら側板の外面に単数又は複数の凹部を垂直方向に形成し、これら側板の上下に底板及び天板の少なくとも左右の縁に立ち上がり部を設け、これら立ち上がり部を垂直に折り曲げて、これら立ち上がり部の夫々の内面に側板の一部を接合した電気機器筐体が開示されている。   In order to achieve weight reduction, [Patent Document 1] describes a case in which an electrical device is housed inside, and a plate-like side plate is provided on each of the left and right sides, and one or a plurality of concave portions are vertically formed on the outer surface of these side plates. Electrical devices in which rising portions are provided at the left and right edges of the bottom plate and the top plate at the upper and lower sides of these side plates, the rising portions are bent vertically, and a part of the side plate is joined to the inner surface of each of the rising portions. A housing is disclosed.

特開2004−296559号公報JP 2004-296559 A

〔特許文献1〕に記載の従来の技術は、左右夫々の側板の外面に単数又は複数の凹部を垂直方向に形成して、筐体側面においても剛性を向上して耐震性を向上させている。しかし、〔特許文献1〕に記載の従来の技術は、制御装置全体の小型軽量化を十分に配慮したものではなく、据付性,環境の悪い場所に設置することを配慮したものではない。   In the conventional technique described in [Patent Document 1], one or a plurality of concave portions are formed in the vertical direction on the outer surface of each of the left and right side plates, and the rigidity is improved also on the side surface of the housing to improve the earthquake resistance. . However, the conventional technology described in [Patent Document 1] does not fully consider the reduction in size and weight of the entire control device, and does not consider installation in a place with poor installation and environment.

本発明の第1の目的は、小型軽量で耐久性がよく、低コストの制御装置を提供することにある。   A first object of the present invention is to provide a control device that is small, light, durable, and low in cost.

本発明の第2の目的は、制御装置の組み立ての作業性がよく、耐環境性に優れた制御装置を提供することにある。   A second object of the present invention is to provide a control device that has good workability in assembly of the control device and is excellent in environmental resistance.

本発明の第3の目的は、屋外の柱上に設置され、耐環境性に優れ、低コスト化を実現できる制御装置を提供することにある。   A third object of the present invention is to provide a control device that is installed on an outdoor pillar, has excellent environmental resistance, and can realize cost reduction.

上記目的を達成するために、本発明の制御装置は、側面部と背面部と天井部が一体化された外壁と、該外壁の内側に設置され外壁に固定される内部筐体と、内部筐体内に設けられた中柱に固定される内部実装ユニットを備え、内部実装ユニットが、上部に制御機器,通信機器及びこれらの機器の電源装置を実装し、下部の正面扉側に保守作業時に必要となる器具を配置し、背面側にノイズフィルタ,電源コンセントを配置してワンユニット化したものである。   In order to achieve the above object, a control device of the present invention includes an outer wall in which a side surface portion, a back surface portion, and a ceiling portion are integrated, an inner housing that is installed inside the outer wall and is fixed to the outer wall, and an inner housing. Equipped with an internal mounting unit that is fixed to the middle pillar provided in the body. The internal mounting unit has control devices, communication devices, and power supply units for these devices mounted on the upper part, and is required for maintenance work on the lower front door side. This is a single unit with a noise filter and a power outlet on the back side.

又、両側の側面部と背面部と天井部が一体化された外壁と、該外壁の内側に設置され外壁に固定される内部筐体と、内部筐体内に設けられた中柱に固定されるワンユニット化した内部実装ユニットを備え、外壁と内部筐体との間に通風路が形成されたものであって、外壁の背面部及び両側の側面部の上部には複数の鎧戸形状の通気孔が、外壁の側面部の複数箇所に設けられた孔と孔内に配置され内部筐体に固定された金具との間に通風用の隙間が形成されているものである。   In addition, an outer wall in which side portions on both sides, a back surface portion, and a ceiling portion are integrated, an inner casing that is installed inside the outer wall and fixed to the outer wall, and a middle pillar provided in the inner casing are fixed. An internal mounting unit is formed as a single unit, and a ventilation path is formed between the outer wall and the inner housing, and a plurality of armor-door-shaped vent holes are formed on the rear portion of the outer wall and on the side portions on both sides. However, a gap for ventilation is formed between a hole provided at a plurality of positions on the side surface portion of the outer wall and a metal fitting disposed in the hole and fixed to the internal housing.

本発明によれば、制御装置の内部実装構造をワンユニット化し、それぞれのユニットの組み立てを正面扉側から順次行えるようにしているので、低コスト化を実現できる。又、器具を1つのユニットに集約的に実装しているので、制御装置内で組立・配線作業をする必要がなく、部材点数も少なくできる。   According to the present invention, the internal mounting structure of the control device is made into one unit, and the assembly of each unit can be performed sequentially from the front door side, so that the cost can be reduced. Further, since the instruments are intensively mounted on one unit, it is not necessary to perform assembly and wiring work in the control device, and the number of members can be reduced.

本発明の一実施例である監視制御装置を図1から図12により説明する。本実施例の監視制御装置は、車番認識装置や河川監視装置に適用される。又、路上における車両を監視するための監視システムやセキュリティー関連の監視システムにも適用される。   A monitoring control apparatus according to an embodiment of the present invention will be described with reference to FIGS. The monitoring control device of this embodiment is applied to a vehicle number recognition device and a river monitoring device. The present invention is also applied to a monitoring system for monitoring vehicles on the road and a security-related monitoring system.

図1に示すように、監視制御装置は、電柱などの柱1に取付け金具4aにより取付けられた制御装置2と、柱1に取付金具4bにより取付けられた撮像装置3,撮像装置3と制御装置2とを接続する伝送ケーブル5で構成される。撮像装置3にて撮影した監視情報は、伝送ケーブル5を介して制御装置2にデータ伝送される。伝送ケーブル5には、LANケーブル,画像取出し用のケーブル及び電力供給用ケーブルが設けられており、LANケーブルにより図示しない中央側の制御装置に信号を送信し、画像取出し用のケーブルにより後述するように、撮像装置3で撮影した或いは撮影している映像を制御装置2のコネクタ20から取出せるようになっている。   As shown in FIG. 1, the monitoring control device includes a control device 2 attached to a pole 1 such as a utility pole by a mounting bracket 4a, an imaging device 3, an imaging device 3, and a control device attached to the pole 1 by a mounting bracket 4b. 2 and a transmission cable 5 for connecting the two. The monitoring information photographed by the imaging device 3 is transmitted as data to the control device 2 via the transmission cable 5. The transmission cable 5 is provided with a LAN cable, an image extraction cable, and a power supply cable. The LAN cable transmits a signal to a control device on the central side (not shown), and the image extraction cable will be described later. In addition, an image captured by the imaging device 3 or an image being captured can be taken out from the connector 20 of the control device 2.

図2は、撮像装置3を分解したときの斜視図である。傾斜や回転方向の調節が可能な土台39の上には、両側に設けられた側面外壁40と背面側壁41を溶接等で一体化した外壁42が取付けられている。外壁42の内側に、内部筐体43が固定され、内部筐体43の内側に内部実装ユニット44が固定されている。内部筐体43は、外壁42にリベット締結されている。   FIG. 2 is a perspective view when the imaging device 3 is disassembled. On the base 39 that can be adjusted in inclination and rotation direction, an outer wall 42 is attached by integrating a side outer wall 40 and a rear side wall 41 provided on both sides by welding or the like. An internal housing 43 is fixed inside the outer wall 42, and an internal mounting unit 44 is fixed inside the internal housing 43. The inner housing 43 is rivet fastened to the outer wall 42.

内部実装ユニット44には、架台45の前面に取付けられたLED照明46,架台45の上部に並置されるカラーカメラ47と高精細カメラ48、2つのカメラの間に設置される図示しない画像処理ボードが設けられワンユニット化されている。   The internal mounting unit 44 includes an LED illumination 46 mounted on the front surface of the gantry 45, a color camera 47 and a high-definition camera 48 juxtaposed on the top of the gantry 45, and an image processing board (not shown) installed between the two cameras. Is provided as a single unit.

カラーカメラ47と高精細カメラ48の上部には、天井部38が取付けられる。カラーカメラ47又は高精細カメラ48で撮影された映像は画像処理ボードで画像処理されて記憶される。例えば、画像処理ボードでは、カメラで撮影した画像を画像処理して車番や車種等の必要なデータに変換し、伝送ケーブル5により撮像装置3から制御装置2に転送する。   A ceiling part 38 is attached to the upper part of the color camera 47 and the high-definition camera 48. Images captured by the color camera 47 or the high-definition camera 48 are subjected to image processing by an image processing board and stored. For example, in the image processing board, an image captured by the camera is subjected to image processing, converted into necessary data such as a car number and a vehicle type, and transferred from the imaging device 3 to the control device 2 through the transmission cable 5.

このように、順次一方向に、土台39の上に一体化した外壁42を取付け、外壁42の内側に内部筐体43を固定し、内部筐体43にワンユニット化した内部実装ユニット44を取付け、天井部38を取付けているで、組み立て時の作業性がよい。又、天井部38を外して調整,点検ができるので、メンテナンス時に高所で一人で作業でき、作業も短時間で行える。又、監視装置にも画像処理ボードを設けているので、制御装置の負担を軽くすることができ、何かの時の画像記録を取出すことができる。   As described above, the outer wall 42 integrated on the base 39 is sequentially attached in one direction, the inner casing 43 is fixed to the inner side of the outer wall 42, and the inner mounting unit 44 formed as one unit is attached to the inner casing 43. Since the ceiling portion 38 is attached, workability at the time of assembly is good. In addition, since the ceiling portion 38 can be removed for adjustment and inspection, it is possible to work alone at a high place during maintenance, and the work can be performed in a short time. Moreover, since the image processing board is also provided in the monitoring device, the burden on the control device can be reduced, and an image record at any time can be taken out.

制御装置2には、図3から図6に示すように、外壁15が設けられている。外壁15には、安価で広く用いられている材料であるステンレス鋼板(SUS304)を用いており、上部に図3に示す天井部6が、両側に図5に示す側面部7が、背面に図6に示す背面部8が配置され、溶接により一体に形成されている。天井部6は、制御装置2が屋外に設置されるため、正面側から背面側に向かって斜め形状になっており、雨水や雪,塵埃などが溜まるのを防止する構造になっている。又、天井部6の鋼板は、側面部7,背面部8,正面扉10の鋼板より、数ミリ大きな外形寸法で形成され、天井部6から滴り雨水や雪が直接地面に落下するようにしてある。   As shown in FIGS. 3 to 6, the control device 2 is provided with an outer wall 15. A stainless steel plate (SUS304), which is an inexpensive and widely used material, is used for the outer wall 15, and the ceiling portion 6 shown in FIG. 3 is shown at the top, the side portion 7 shown in FIG. 6 is disposed and formed integrally by welding. Since the control device 2 is installed outdoors, the ceiling portion 6 has an oblique shape from the front side to the back side, and has a structure that prevents rainwater, snow, dust, and the like from accumulating. Further, the steel plate of the ceiling portion 6 is formed with an outer dimension several millimeters larger than the steel plate of the side surface portion 7, the back surface portion 8, and the front door 10, so that dripping rainwater or snow directly falls on the ground from the ceiling portion 6. .

このように、制御装置の外壁を一体化構造にしているので、耐環境性を向上させ、且つ低コスト化を実現できる。又、外壁を一体構造にしているので、外部からの電波や内部から発生する電波に対しシールド効果が向上し、外部からの衝撃に対する耐衝撃性が向上する。   Thus, since the outer wall of the control device has an integrated structure, it is possible to improve the environmental resistance and reduce the cost. In addition, since the outer wall has an integrated structure, the shielding effect against external radio waves and radio waves generated from the inside is improved, and impact resistance against external impacts is improved.

又、外壁の天井部を前後に傾斜させ、屋根のように天井から下の外壁を覆うような形状にしているので、雨水や雪,大気に浮遊する塵埃などが堆積することによる筐体の劣化を防止でき、柱上における風圧を分散させることができる。又、両側面や背面,正面部も同様に雨水や雪,大気に浮遊する塵埃などが堆積することによる劣化を抑制することができる。   In addition, the ceiling of the outer wall is tilted back and forth so that the outer wall below the ceiling is covered like a roof, so that deterioration of the case due to accumulation of rainwater, snow, dust floating in the atmosphere, etc. Can be prevented, and the wind pressure on the column can be dispersed. Similarly, deterioration due to accumulation of rainwater, snow, dust floating in the atmosphere, and the like can be suppressed on both side surfaces, the back surface, and the front surface portion.

一方の側面部7には上下に設けられたヒンジ9により正面扉10が取付けられている。背面部8の上部には通風用の鎧戸形状の通気孔11(排気孔11ともいう)が縦方向3箇所,横方向3箇所に設けられ、両側の側面部7の上部にも通風用の鎧戸形状の通気孔11が横方向2箇所に設けられている。両側の側面部7のそれぞれには上下2箇所ずつ孔12が設けられ、その孔12には後述する内部筐体14の金具13が位置するようになっている。金具13と孔12との間には通風用の隙間が設けられている。   A front door 10 is attached to one side surface portion 7 by hinges 9 provided vertically. On the upper part of the back part 8 are ventilating-shaped vents 11 (also called exhaust holes 11) for ventilation in three places in the vertical direction and three places in the horizontal direction, and also in the upper part of the side parts 7 on both sides. Shaped air holes 11 are provided in two places in the horizontal direction. Each of the side portions 7 on both sides is provided with two holes 12 at the top and bottom, and a metal fitting 13 of an internal housing 14 to be described later is positioned in the hole 12. A gap for ventilation is provided between the metal fitting 13 and the hole 12.

このように、外壁の両側面と背面の上部に、鎧戸形状の複数の通気孔を設けているので、制御装置の内部筐体から発生する熱を排気でき、外部の日射などによる受熱を内部筐体に熱伝達することなく排気することができる。又、柱上に設置されるので、微風であっても制御装置の底面より冷たい風を内部筐体と外壁の隙間に効率よく通気できる。又、鎧戸形状の機械加工を一発成型で行うことにより製作コストを上げることなく、鎧戸形状に通気孔を形成でき、鎧戸形状に通気孔により外部から雨水や雪,大気に浮遊する塵埃などが外壁内部へ侵入するのを防止できる。   As described above, since the plurality of armor-shaped vents are provided on both sides and the upper part of the back of the outer wall, the heat generated from the inner casing of the control device can be exhausted, and the heat received by external solar radiation and the like can be exhausted. It can be exhausted without transferring heat to the body. Moreover, since it is installed on a pillar, even if it is a light wind, the air cooler than the bottom surface of the control device can be efficiently ventilated into the gap between the inner casing and the outer wall. In addition, it is possible to form a vent hole in the shape of the armor door without increasing the production cost by performing machining of the armor door shape by one-shot molding, and rain, snow, dust floating in the atmosphere etc. from the outside by the vent hole in the armor door shape. Intrusion into the outer wall can be prevented.

金具13は、制御装置2の一方の側面で柱1に取付けるためのもので、いずれの方向からでも制御装置2を柱1に取付けられるように、両側の側面部7に4つの正方形の孔12を設けられる。例えば、既設の柱1に制御装置2を設置する場合、既設の柱1には信号機や標識などが既に取付けられており、これらの既に取付けられた信号機や標識に影響を与えることなく設置するために、図1に示すように制御装置2の右側面で柱1に設置できない場合、左側面で柱1に設置できるような構造になっている。内部筐体14に直接溶接された凹凸形状の金具13の凸部が外壁15の孔12の中央部となるように配置されている。   The metal fitting 13 is for attaching to the pillar 1 on one side surface of the control device 2, and four square holes 12 are formed in the side surface portions 7 on both sides so that the control device 2 can be attached to the pillar 1 from any direction. Is provided. For example, in the case where the control device 2 is installed on the existing pillar 1, traffic lights and signs are already attached to the existing pillar 1, and these are installed without affecting the already installed traffic lights and signs. In addition, as shown in FIG. 1, when the control device 2 cannot be installed on the pillar 1 on the right side, the structure can be installed on the pillar 1 on the left side. The convex portion of the concavo-convex metal fitting 13 welded directly to the inner housing 14 is arranged so as to be the central portion of the hole 12 of the outer wall 15.

外壁15の内側には、図9に示すように、内部筐体14が挿入され外壁15に設けられたネジ座にネジ止めされて固定される。ネジ座への固定は内部筐体14の内側からネジを取付けることにより行われる。内部筐体14の正面側には正面扉52がヒンジ51により取付けられている。正面扉52の内側に下部にはヒータ50が設けられ、図示しない温度センサからの検出値に基づいてヒータ50の入り切りの制御が行われる。ヒータ50により内部筐体14内を加熱して凍結防止、あるいは結露防止を行っている。正面扉52の上下2箇所に止め具53が設けられ、気密性を向上させている。   As shown in FIG. 9, the inner housing 14 is inserted inside the outer wall 15 and fixed by screwing to a screw seat provided on the outer wall 15. Fixing to the screw seat is performed by attaching a screw from the inside of the inner casing 14. A front door 52 is attached to the front side of the internal housing 14 by a hinge 51. A heater 50 is provided in the lower part inside the front door 52, and on / off control of the heater 50 is performed based on a detection value from a temperature sensor (not shown). The inner casing 14 is heated by the heater 50 to prevent freezing or condensation. Stops 53 are provided at two locations above and below the front door 52 to improve airtightness.

外壁15と内部筐体14との間には、図7,図8に示すように、制御装置2の正面側,背面側,両側の側面側に通風路18が形成される。屋外では、内部筐体14内部の制御機器の発熱と、日射などにより外壁15が加熱されるため、通風路18は加熱されている。底面部17には吸気孔16が設けられており、吸気孔16から吸込まれた空気は内部筐体14の外面と外壁15の内面との間に形成される空間で受熱して上昇し、金具13と孔
12との間の隙間及び外壁15の上部に設けられた排気孔11から排気される。このため、制御装置2の底面17では微風でも効率よく吸気できるので、外壁15と内部筐体14との間を通風させて内部筐体14を冷却できる。
As shown in FIGS. 7 and 8, an air passage 18 is formed between the outer wall 15 and the inner housing 14 on the front side, the back side, and the side surfaces of both sides of the control device 2. Outside, the outer wall 15 is heated by heat generated by the control device inside the inner housing 14 and solar radiation, so the ventilation path 18 is heated. The bottom surface portion 17 is provided with an air intake hole 16, and the air sucked from the air intake hole 16 receives and rises in a space formed between the outer surface of the inner housing 14 and the inner surface of the outer wall 15, The air is exhausted from the gap between the hole 13 and the hole 12 and the exhaust hole 11 provided in the upper part of the outer wall 15. For this reason, since the bottom surface 17 of the control device 2 can efficiently intake air even with a slight wind, the internal housing 14 can be cooled by passing air between the outer wall 15 and the internal housing 14.

又、柱1上に設置される制御装置2では、地上に設置される制御装置より、強く風が吹き上げられるので自然冷却能力は高くなる。制御装置2の底面部17から吹き上げられた風は、内部筐体14から放射される熱と外部の日射により受ける熱を冷却し、外壁15の側面部7の通気孔11と正方形状の孔12の隙間から排気される。又、背面部8の通気孔11,正面扉10と天井部49の隙間から排気される。一体化された外壁15は、日射による温度上昇が最も大きい天井部49に大きい空間を形成し、加熱された空気が上昇し易くし、柱上に設置する場合に有利な点である装置の底面部17からの風を効率よく吸込む構造になっている。   Moreover, in the control apparatus 2 installed on the pillar 1, since a wind is blown up stronger than the control apparatus installed on the ground, natural cooling capability becomes high. The wind blown from the bottom surface portion 17 of the control device 2 cools the heat radiated from the internal housing 14 and the heat received by external solar radiation, and the air holes 11 and the square holes 12 in the side surface portion 7 of the outer wall 15. Exhausted through the gap. Further, the air is exhausted through the air holes 11 in the back surface portion 8 and the gaps between the front door 10 and the ceiling portion 49. The integrated outer wall 15 forms a large space in the ceiling portion 49 where the temperature rise due to solar radiation is greatest, which makes it easy for heated air to rise, and is an advantageous point when installed on a pillar. The structure is configured to efficiently suck the wind from the portion 17.

このように、一体化された外壁15と内部筐体14,ワンユニット化された内部実装ユニット19を、図9に矢印で示すように一方向から組み立てることができる。又、内部実装ユニット19をワンユニット化することにより、内部筐体14内の狭い空間で、器具を取付ける作業や器具間の配線する作業を行う必要がなくなり、内部実装ユニット19の組み立てや配線は、内部筐体14の外で行うため、作業効率が向上し、配線ミス等が少なくて内部筐体14に実装することができる。又、内部実装ユニット19の軽量化のため、ユニットを構成する部材に各方向の孔を設け、内部筐体14に効率よく熱伝達させている。   In this way, the integrated outer wall 15, inner housing 14, and unitized internal mounting unit 19 can be assembled from one direction as indicated by arrows in FIG. 9. Further, by making the internal mounting unit 19 as a single unit, it is not necessary to perform the work of mounting the equipment or the work of wiring between the equipment in the narrow space in the internal housing 14, and the assembly and wiring of the internal mounting unit 19 can be performed. Since the operation is performed outside the internal housing 14, the working efficiency is improved, and the wiring can be mounted on the internal housing 14 with few wiring errors. Further, in order to reduce the weight of the internal mounting unit 19, holes in each direction are provided in the members constituting the unit so that heat is efficiently transmitted to the internal housing 14.

内部筐体14の内側には、内部実装ユニット19がはめ込まれ、内部筐体14に設けられた中柱21にネジ止めされる。中柱21には、画像取出し用のコネクタ20が設けられている。内部実装ユニット19は、枠体22の下部に電源部29が取付けられ、上部に制御ユニット23が取付けられている。   An internal mounting unit 19 is fitted inside the internal housing 14 and is screwed to a middle column 21 provided in the internal housing 14. The middle column 21 is provided with an image extraction connector 20. The internal mounting unit 19 has a power supply unit 29 attached to the lower part of the frame 22 and a control unit 23 attached to the upper part.

上部の制御ユニット23には、制御機器,通信機器及びこれらの機器の電源である電源装置が実装されている。制御ユニット23は、データを伝送するためのルータ24と、インターネット用として使用され例えばBフレッツ対応のルータ25と、CPUとメモリ素子が搭載されたSBC26と、定電圧電源(AVR)27等で構成され、それぞれ枠体
22に取付けられている。SBC26のメモリ素子には、撮像装置3の画像処理ボードで画像処理されたデータが伝送ケーブル5を介して転送されて記憶される。SBC26では、メモリ素子に記憶されたデータを中央側のサーバに転送するため、暗号化などのセキュリティー処理を施してルータ24又はルータ25を介して中央側に転送する。
The upper control unit 23 is mounted with a control device, a communication device, and a power supply device that is a power source of these devices. The control unit 23 comprises a router 24 for transmitting data, a router 25 used for the Internet, for example, a B FLET'S compatible router 25, an SBC 26 equipped with a CPU and memory elements, a constant voltage power supply (AVR) 27, and the like. And attached to the frame 22 respectively. In the memory element of the SBC 26, data processed by the image processing board of the imaging device 3 is transferred and stored via the transmission cable 5. In the SBC 26, in order to transfer the data stored in the memory element to the server on the central side, security processing such as encryption is performed and the data is transferred to the central side via the router 24 or the router 25.

電源部29には、工事者あるいは保守員が工事あるいは点検時に作業し易いように、正面扉10側に受電の入り切りを行う遮断器35,外部とのデータ伝送するインターフェイス端子台32,電源の保安器34,ユニット内の機器を保護するヒューズ33,保守用のコンセント30,通信アクセスコネクタ31が配置されている。電源部29には、背面部8側に受電した電源の整流化を行うノイズフィルタ36,上部に設置される制御機器,通信機器の電源コンセント37等が配置されている。これらノイズフィルタ36,電源コンセント37は、部品が故障しない限り交換することがない。   The power supply unit 29 includes a circuit breaker 35 for turning on / off the power reception on the front door 10 side, an interface terminal block 32 for transmitting data to / from the outside, and security of the power supply so that a construction worker or maintenance staff can easily work during construction or inspection. A unit 34, a fuse 33 for protecting the devices in the unit, a maintenance outlet 30, and a communication access connector 31 are arranged. The power supply unit 29 is provided with a noise filter 36 for rectifying the received power on the back surface 8 side, a control device installed on the upper side, a power outlet 37 for communication devices, and the like. The noise filter 36 and the power outlet 37 are not replaced unless parts are broken.

このように、保守品であるヒューズ33,保守作業時に必要となるコンセント30,据付作業時に必要となる撮像装置とのデータ送受信するインターフェイス端子台32を正面側に実装しているので、保守性や据付作業性が向上する。   As described above, the fuse 33, which is a maintenance product, the outlet 30 required for maintenance work, and the interface terminal block 32 for transmitting and receiving data to and from the imaging device required for installation work are mounted on the front side. Installation workability is improved.

外部の電源からの受電する図示しない受電ケーブルは、遮断器35の一次側である上段端子部に配線され、遮断器35の二次側である下段端子部からヒューズ33に接続される。ヒューズ33の出力側は分岐され、一方は電源の保安器34に、他方は保守用のコンセント30に接続されている。電源の保安器34は裏面のノイズフィルタ36の下段端子に接続され、ノイズフィルタ36の上段端子から分岐して通信機器の電源コンセント37と、ノイズフィルタ36の上部の制御ユニット23に実装された定電圧電源(AVR)27に接続されている。   A power receiving cable (not shown) that receives power from an external power source is wired to the upper terminal portion that is the primary side of the circuit breaker 35, and is connected to the fuse 33 from the lower terminal portion that is the secondary side of the circuit breaker 35. The output side of the fuse 33 is branched, and one is connected to a power protector 34 and the other is connected to a maintenance outlet 30. The power protector 34 is connected to the lower terminal of the noise filter 36 on the back surface, branches from the upper terminal of the noise filter 36, and is mounted on the power outlet 37 of the communication device and the control unit 23 above the noise filter 36. A voltage power supply (AVR) 27 is connected.

このように、遮断器35,電源の保安器34の電源一次側の配線を短くでき、耐ノイズ性が良い。又、電源二次側の配線も短くでき、一次側と二次側が分離した両面実装配置になっている。   Thus, the power supply primary side wiring of the circuit breaker 35 and the power supply protector 34 can be shortened, and the noise resistance is good. In addition, the wiring on the secondary side of the power supply can be shortened, and the double-sided mounting arrangement in which the primary side and the secondary side are separated is employed.

図12は、本実施例の制御装置の組み立てた状態を示す斜視図である。図9で示したように、一体化された外壁15に内部筐体14,ワンユニット化された内部実装ユニット
19を順番に実装しており、内部筐体14の正面扉52,外壁15に取付けられた正面扉10を閉じるようになっている。保守や据付作業時に正面扉52,10が可動しないように、内側の正面扉52と外側の正面扉10の回転軸に付近に金具28を挿入できるように穴加工が施されており、正面扉52と正面扉10を一括して固定している。
FIG. 12 is a perspective view showing the assembled state of the control device of this embodiment. As shown in FIG. 9, the internal housing 14 and the internal mounting unit 19, which are integrated into one unit, are sequentially mounted on the integrated outer wall 15 and attached to the front door 52 and the outer wall 15 of the internal housing 14. The front door 10 is closed. In order to prevent the front doors 52 and 10 from moving during maintenance and installation work, holes are drilled so that the metal fittings 28 can be inserted in the vicinity of the rotation shafts of the inner front door 52 and the outer front door 10. 52 and the front door 10 are fixed together.

本実施例の屋外の柱上に設置する制御装置では、耐環境性の向上が図られ、低コスト化が実現できる。従来の制御装置と比較して、製品重量が−40%、部品点数が1/2、製造コストが−45%低減することが可能となる。   In the control device installed on the outdoor pillar of this embodiment, the environmental resistance is improved and the cost can be reduced. Compared with the conventional control device, the product weight can be reduced by -40%, the number of parts can be reduced by 1/2, and the manufacturing cost can be reduced by -45%.

又、制御装置の内部実装構造をワンユニット化し、それぞれのユニットの組み立てを正面扉側から順次行えるようにしているので、低コスト化を実現できる。本実施例の制御装置では、器具を1つのユニットに集約的に実装しているので、制御装置内で組立・配線作業をする必要がなく、部材点数も少なくできる。又、ユニット内の器具実装配置は、電源部と保守部に分けて両面実装しているので、配線距離を短くすることができる。   Moreover, the internal mounting structure of the control device is made into one unit, and the assembly of each unit can be performed sequentially from the front door side, so that the cost can be reduced. In the control device of this embodiment, since the instruments are intensively mounted on one unit, it is not necessary to perform assembly and wiring work in the control device, and the number of members can be reduced. Moreover, since the instrument mounting arrangement in the unit is mounted on both sides separately for the power supply unit and the maintenance unit, the wiring distance can be shortened.

又、内部ユニット,内部筐体,外壁を同一方向に順次組み立てられるようにしているので、組み立て作業時間が短縮され、柱上に設置された不安定な場所でも、制御装置の保守やトラブル発生時に容易に交換できる。   In addition, because the internal unit, internal housing, and outer wall can be assembled sequentially in the same direction, the assembly work time is shortened, even when the controller is under maintenance or trouble occurs even in an unstable place installed on a pillar. Can be easily replaced.

柱上に設置する制御装置の場合、重量制限や外形の寸法制限があるため、実装する器具や機器は、小型なものを使用することが多いが、一人で作業できるので、作業効率が飛躍的に向上する。   In the case of a control device installed on a pillar, there are weight restrictions and external dimensions restrictions, so the equipment and equipment to be mounted are often small, but the work efficiency can be dramatically improved because one person can work alone. To improve.
