  For example, at railroad crossing facilities such as railways, vehicle entrance / exit gate facilities at parking lots, user entrance / exit gates at facilities such as theme parks and amusement parks, and vehicle entrance / exit gates at expressway tollgates, etc. In addition, a circuit breaker is provided to restrict the passage of vehicles and passers-by such as trains, cars, buses, trucks, and bicycles. A general circuit breaker includes a circuit breaker and a mechanism that raises and lowers the circuit breaker. This blocking can sometimes be broken or damaged when the vehicle or a passerby tries to pass by force when the vehicle or a passerby is blocked or when the vehicle or passer-by is moving up or down. When the barrier is broken or damaged, it is generally found from the driver or passerby of the vehicle to the manager, or by checking by the manager.

  Various means for detecting breakage or breakage of the shield can be proposed. In the following, main abnormality detection means relating to main blockers will be described.

  In Patent Document 1, a fan made of a material that reflects a radio signal is provided at the tip of the shield can, and a speed sensor is attached to the base of the shield. The speed sensor transmits a radio signal toward the fan and reflects it to the fan, and measures the rotational speed of the fan based on the received radio signal. It is described that the measured rotation speed is output to an abnormality detection unit and compared with a threshold value to determine whether or not there is an abnormality.

  For example, when a breaker provided at a railroad crossing breaker breaks or breaks, the operation of the train must be restricted to replace the breaker. Furthermore, it is necessary to confirm the safety even after the replacement work is completed, and breakage or breakage of the shut-off can lead to train delays or disruption of the schedule. Therefore, it is a problem to be a system that can quickly detect and deal with an abnormality in the shape that occurs during the shut-off.

  In addition, regarding an abnormality in the shut-off can, if erroneous detection occurs due to, for example, the influence of weather conditions or environmental conditions, useless work occurs. In addition, if the degree of abnormality that occurs during the shut-off cannot be accurately grasped, appropriate measures cannot be taken and time is wasted. Therefore, it is a problem to be a system that can stably detect an abnormality that has occurred in a shut-off state and can accurately grasp the state of the abnormality.

  In addition, because the shape abnormality that occurs in the shut-off can always occur, it is a low-cost and simple system that can withstand long-term use, especially the shut-off can with a power-saving power supply system The problem is that it is a determination system.

  An object of the present application is to solve such a problem and to provide a shut-off can shape determination system capable of quickly, stably and simply detecting a shape abnormality occurring in the shut-off can.

  In order to achieve the above-mentioned object, a shut-off can shape determination system according to the present invention is a shut-off can shape determination system for determining the shape of a shut-off can, and a plurality of wireless devices provided in the periphery of the shut-off can or the shut-off can, A radio control unit that controls each of a plurality of radio units, and a shape determination unit that determines the shape of the shut-off cannula based on information on the communication state between radio units transmitted from the radio unit control unit, To do.

  With the above-described configuration, for example, a wireless device is provided in a breaker such as a breaker, and the state of the shape of the breaker can be determined based on the communication state between the wireless devices. The principle of the present invention is that when there is no abnormality in the shape of the shut-off can, radio communication is established and linked between the radio units provided at the positions to be approached by raising and lowering the shut-off can. It can be determined that there is no problem. However, when an abnormality occurs in the shape of the shut-off can, it is possible to determine that there is a problem in the shape of the shut-off can because the wireless devices do not establish wireless communication and do not link.

  In order to determine the state of the shape of the block according to whether or not the wireless communication is performed by wireless communication between the wireless devices, a short-range wireless communication technology is applied. That is, the communication area is limited, and an abnormality in the shape of the shut-off can be quickly determined by communication between wireless devices by non-directional short-range wireless communication. Moreover, since it is wireless communication, it is hard to be influenced by weather conditions and environmental conditions, and it is possible to stably detect an abnormality in a shut-off can. In addition, it is possible to easily detect an abnormality in the shape of the shut-off can only by installing a simple device such as a wireless device at the appropriate place in the shut-off can or the periphery of the shut-off can. In addition, since the communication area is limited, it can be accurately determined whether or not the wireless devices are approaching each other. Furthermore, by using omnidirectional wireless communication, it is possible to perform stable detection that is not easily affected by disturbance, and it is possible to perform simple detection with low cost and low power consumption.

  Further, in the shut-off can shape determination system, a radio is provided at each tip portion of the both-arms type shut-off can, and the shape determination unit is connected to the radios transmitted from at least one of the radio control units when the crossing is closed. It is preferable that it is determined that there is no problem in the shape of the two-arm type shut-off can based on the link establishment information. Thereby, in the case of a two-arm type shut-off can, in both of the shut-off cans, radio devices are provided at both front end portions that should be approached when the shut-off can is dropped. In other words, when wireless communication is not established and the links are not established because the leading ends of the both shut-off cans do not approach, it can be estimated that an abnormality has occurred in at least one of the shut-off cans.

  In addition, the shape determination system is provided with a radio at the tip of the one-armed type shut-off can and the peripheral part where the tip of the shut-off can with no shape problem approaches when the railroad crossing is closed. Preferably, the unit determines that there is no problem in the shape of the one-arm type shut-off cannula based on the information on the establishment of the link between the radios transmitted from at least one radio unit control unit. Thereby, in the case of a one-arm type shut-off can, a radio is provided at the tip of the shut-off can when the railroad crossing is closed and the peripheral portion of the shut-off can which the tip should approach. That is, when the front end portion of the shut-off can and the peripheral portion of the shut-off can not approach and wireless communication is not established and the link is not established, it can be estimated that an abnormality has occurred in the shape of the shut-off can.

  In addition, in the shut-off can shape determination system, the radio is further provided at the intermediate portion of the shut-off can and the peripheral portion where the front end and the intermediate portion of the shut-off can which have no problem in shape when the railroad crossing is approached respectively. Preferably, the shape determining unit determines that there is no problem with the shape of the shut-off can at least on the railroad crossing based on the information on the establishment of communication between the wireless devices transmitted from at least one of the wireless device control units. As a result, when the breaker is on the railroad crossing, radios are provided at the front end and the intermediate part of the breaker and the peripheral part of the breaker to which the front and intermediate parts should approach. That is, when the front end and the intermediate portion of the barrier can be separated from the position to be approached when the railroad crossing is on, it can be estimated that an abnormality has occurred in the shape of the barrier.

Further, in the shut-off can shape determination system, the shape determining unit performs mutual radio communication between a radio set provided at the tip or intermediate portion of the shut-off can and a radio set provided in a peripheral portion corresponding to the radio set. It is preferable to determine the linearity of the blocking can according to the strength of. As a result, the wireless devices are provided not only at the front end portion of the shut-off can but also at the peripheral portion of the shut-off can which the intermediate portion should approach. When the intermediate part of the barrier is away from the position that should be approached when crossing the railroad crossing, the separation distance is estimated from the strength of the communication radio wave of the wireless unit in the intermediate part. The deformation of the can shape can be estimated.
be able to.

  In the shut-off can shape determination system, it is preferable that the radio is provided with the battery inside the shut-off can and a solar power generation panel for supplying electric power to the battery is provided around the shut-off can. As a result, the wireless device is installed inside the shut-off can and is protected from theft, failure, deterioration, and the like. Further, power is supplied to the battery provided inside the shut-off can by the solar power generation panel, thereby realizing power saving by sustainable energy.

  Moreover, it is preferable that a solar-power generation panel is provided in the inside of a interruption | blocking can, and the interruption | blocking canal shape determination system generates electric power with the sunlight which injected from the light transmission part provided in a part of the interruption | blocking can. Thereby, the photovoltaic power generation panel itself is also provided inside the shut-off can and is protected from theft, failure, deterioration, and the like. And a photovoltaic power generation panel, a battery, and a radio can be integrated into a compact interior of the shut-off can, and wiring from the radio controller to the radio can be omitted.

  Furthermore, it is preferable that the cut-off can shape determination system can be linked to each other by wireless communication means having a short communication area because the wireless device is non-directional and has low power. As described above, since the wireless device is non-directional, it is difficult to receive disturbance due to other radio waves, and the low power can limit the communication area and increase the detection accuracy. Furthermore, the position can be easily detected by a simple result of whether the wireless devices are close to each other and linked to each other or whether the wireless devices are separated from each other and are not linked to each other.

  As described above, according to the shut-off can shape determination system according to the present invention, it is possible to quickly, stably and easily detect an abnormality in the shape generated in the shut-off can.

  Below, it demonstrates in detail about the interruption | blocking cane shape determination system 1 which concerns on this invention using drawing. In the present specification, the breaker shape determination system 1 in the breaker 2 provided in the passage 10 crossing the railroad track will be described as an example. However, the present invention is not limited to this, and the entrance / exit gate facility of the vehicle in the parking lot, the theme park, The present invention may also be applied to user entry / exit gates at facilities such as amusement parks and vehicle entry / exit gates at highway tollgates. FIG. 1 shows a schematic configuration of a system in which wireless device main bodies 4a and 4b are provided at both end portions 12 of the shut-off cans 3a and 3b of the two-arm type shut-off device 2A as the first embodiment.

(First embodiment of shut-off can shape determination system)
The shut-off can shape determination system 1a includes a pair of wireless device bodies 4a and 4b that perform wireless communication with each other, wireless device control units 5a and 5b that control transmission and reception of the wireless device bodies 4a and 4b, and a transmission and reception unit 6a that transmits and receives wireless signals. 6b, a link determination unit 7 that determines the presence or absence of a link from the communication information between the radio main units 4a and 4b, a shape determination unit 8 that determines the state of the shape of the blocking cans 3a and 3b, and power to the radio main unit 4 Power supply units 9a and 9b. The radio equipment control units 5a and 5b and the link determination unit 7 may be integrated. Further, the wireless device bodies 4a and 4b may be the wireless device body 4 including the transmission / reception units 6a and 6b.

  In the case of the two-arm type breaker 2A, the radio main bodies 4a and 4b are provided at the distal end portion 12 of the blocking rods 3a and 3b of the two-arm type breaker 2A. When the barrier cans 3a and 3b are dropped and installed at a substantially horizontal position when the railroad crossing is closed, the radio main bodies 4a and 4b provided at the distal end portion 12 of the barrier cans 3a and 3b communicate with each other wirelessly. Approach the possible distance. The radio control units 5a and 5b instruct the radio main bodies 4a and 4b to perform transmission using a radio transmission pattern, which will be described later. In addition, it receives radio waves transmitted from the other party. If there is a problem with the shape of the blocking cans 3a and 3b, these wireless transmissions and receptions are established and the wireless device bodies 4 are linked.

  The link determination unit 7 determines the presence or absence of a link from the communication information between the wireless device main bodies 4a and 4b. When one radio control unit 5a receives a radio signal from the other radio control unit 5b, it is determined that a link has been established by mutual radio communication. That is, the link establishment is determined based on the AND condition from the wireless communication results of the wireless device controllers 5a and 5b. However, when one radio control unit 5a receives a radio signal from the other radio control unit 5b, the other radio control unit 5b does not receive a radio signal from one radio control unit 5a. Even if it exists, you may judge that the link was established by mutual radio | wireless communication. That is, it may be determined that the link is established from the wireless communication results of the wireless device control units 5a and 5b even under the OR condition.

  Here, in FIG. 1, the respective communication areas of the wireless device main body 4a at the distal end portion 12 of both arms are indicated by symbols P1 and P2. A link is established if the other radio device body 4 exists in the communication areas P1 and P2. Therefore, the communication range of the wireless device main body 4a is selected in accordance with the range in which the end portions 12 of the blocking cans 3a and 3b actually approach each other when the crossing is closed. In the present embodiment, the wireless device body 4 is used for short-range wireless communication, and employs the wireless device body 4 having a communication range of about 1 m to 2 m. Thereby, it becomes a power saving compared with another communication means, and the shape of the blocking can 3 can be determined easily. Further, the wireless device body 4 uses non-directional wireless. This is because if the directivity is strong, a disturbance from the direction in which the light is directed is strongly received. As described above, by adopting the non-directional radio main body 4 with a narrow communication area, it is possible to accurately determine the shape abnormality occurring in the shut-off can 3.

(Second embodiment of the shut-off can shape determination system)
FIG. 2 shows a second embodiment of the breaker cane shape determination system 1b, which is a breaker 3 of a one-armed breaker 2B and a peripheral part 11 of the breaker 3, and a distal end radio main body 4A and a peripheral part radio. A schematic configuration when a main body 4C is provided is shown. The distal end wireless device body 4 </ b> A is provided at the distal end portion 12 of the blocking can 3. The peripheral wireless device main body 4C is provided in the peripheral portion 11 to which the distal end portion 12 of the shut-off can 3 has no problem in shape when the railroad crossing is closed. In addition, when the barrier 3 is dropped and installed at a substantially horizontal position when the railroad crossing is closed, the distal end radio main body 4A provided at the distal end 12 of the barrier 3 and the periphery provided at the peripheral portion 11 The wireless main unit 4C approaches a distance that allows wireless communication with each other. The radio control units 5a and 5b instruct the radio units 4A and 4C to perform transmission by a radio transmission pattern, which will be described later, and receive radio transmitted from the other party. If there is no problem in the shape of the blocking can 3, these radio transmissions and receptions are established and linked to each other.

  The link determination unit 7 determines the presence / absence of a link from the communication information between the wireless device main bodies 4A and 4C. When one radio control unit 5a receives a radio signal from the other radio control unit 5b, it is determined that a link has been established by mutual radio communication. That is, the link establishment is determined based on the AND condition from the wireless communication results of the wireless device controllers 5a and 5b. However, when one radio control unit 5a receives a radio signal from the other radio control unit 5b, the other radio control unit 5b does not receive a radio signal from one radio control unit 5a. Even if it exists, you may judge that the link was established by mutual radio | wireless communication. That is, the link establishment may be determined from the wireless communication results of the wireless device control units 5a and 5b even under the OR condition.

  Here, in FIG. 2, the communication areas of the distal end wireless device main body 4A and the peripheral wireless device main body 4C are denoted by reference signs P1 and P2. A link is established if the other radio device body 4 exists in the communication areas P1 and P2. Accordingly, the communication range of the wireless device main body 4 is selected in accordance with the range in which the front end portions 12 of the blocking can 3 are actually approached when the crossing is closed. In the present embodiment, the wireless device body 4 is a wireless device used for short-range wireless communication, and employs the wireless device body 4 with a communication range of about 1 m to 2 m. Thereby, it becomes power-saving compared with another communication means, and the shape of the blocking can 3 can be determined easily. In addition, the wireless device main body 4 is omnidirectional. This is because if the directivity is strong, a disturbance from the direction in which the light is directed is strongly received. In this way, by adopting the non-directional radio main body 4 with a narrow communication area, it is possible to accurately determine the shape abnormality occurring in the shut-off can 3.

(Third embodiment of shut-off can shape determination system)
FIG. 3 shows a case where the distal end radio main body 4A and a plurality of intermediate radio main bodies 4B are provided at the front end 12 and the intermediate portion 13 of the circuit breaker 2, which is the third embodiment of the interrupter shape determination system 1c. Indicates. This third embodiment is applied to both the two-arm type circuit breaker 2A and the one-arm type circuit breaker 2B. In addition, although the intermediate | middle radio | wireless machine main body 4B provided in the intermediate part 13 of the circuit breaker 2 is four pieces, it is not restricted to this number.

  FIG. 3A shows the shut-off cans 3a and 3b when the shut-off device 2 is closed. The distal end wireless device main body 4A is provided at the distal end portion 12 of the shut-off cans 3a and 3b, and a plurality of intermediate wireless device main bodies 4B are provided at the intermediate portion 13 of the shut-off cans 3a and 3b. The positions of the intermediate wireless device main body 4B may be the same interval or different intervals. Here, as shown in FIG. 3 (a), when there is no abnormality in the shape of the shut-off cans 3a and 3b, the radio units 4A and 4B provided on the shut-off cans 3a may be any combination. It is assumed that the wireless communication is not established and the link is not established because it is out of the communication area.

FIG. 3B shows a case where, when the breaker 2 is raised or lowered, for example, a vehicle trying to pass through the passage 10 comes into contact with the breaker 3 a and breaks at the intermediate portion 13. At this time, if that radio communication with a blocking cans 3a of the tip wireless device body 4A and the middle portion radio body 4B ₂ shown in FIG. 3 (a) holds, abnormality occurs in the shape of a cut-off cans 3a Can be estimated. That is, as described above, when there is no problem in the shape of the shut-off can 3a, when the shut-off device 2 is raised or lowered, the two wireless device main bodies 4A, When 4B wireless communication is established, it is presumed that the shape is abnormal and approached. Moreover, the shape after the deformation | transformation of the broken shield 3a can be estimated by the radio | wireless communication of the combination of which radio equipment main body 4A, 4B is linked.

  FIG. 3 (c) shows a shut-off can 3a when the breaker 2 is hoisted. The distal end radio main body 4A or the intermediate radio main body 4B of the shut-off can 3a approaches the peripheral radio main body 4C provided in the peripheral portion 11 of the shut-off can 3a. Each peripheral wireless device main body 4C is provided at a position where wireless communication is established and linkable with the distal end wireless device main body 4A or the intermediate wireless device main body 4B when the blocking can 3a is raised. Therefore, if there is a peripheral wireless device main body 4C where the link is not established, it can be estimated that an abnormality has occurred in the shape of the shut-off can 3a.

  Furthermore, the shape determination unit 8 includes a distal end wireless device body 4A or an intermediate wireless device body 4B of the breaker can 3a, and a peripheral wireless device body provided in the peripheral portion 11 corresponding when the breaker 2 is lifted. The linearity of the blocking can 3a can be determined based on the strength of mutual wireless communication with 4C. That is, when the blocking can 3a is not broken, but deformed, for example, bent, warped or twisted, the wireless communication between the corresponding radio main bodies 4 is performed in the state shown in FIG. Strength is generated. By dropping this in the figure, the non-linearity over the entire length of the blocking can 3a becomes clear.

FIG. 4 shows a wireless communication pattern in the case where the wireless device main bodies 4A and 4B are provided at the distal end portion 12 and the intermediate portion 13 of the shut-off can 3a. FIG. 4 (a) shows the positions of the distal end wireless device main body 4A and the intermediate wireless device main body 4B provided on the shut-off can 3a. FIG. 4B shows a time chart of the communication pattern between the wireless device bodies 4A and 4B. In FIG. 4B, the horizontal axis indicates time (t), the vertical axis indicates communication strength (p), the value when wireless communication is OFF is “α”, and the wireless communication is ON. The value is “β”. As shown to Fig.4 (a), the wireless communication of the front-end | tip part radio | wireless machine main bodies 4A provided in the right-and-left blocking cans 3a and 3b is shown by (1). Further, the distal end wireless device main body 4A and the intermediate wireless device main body 4B ₁ are provided at a distance where wireless communication is possible, and the wireless communication is indicated by (2).

As shown in FIG. 4B, each wireless communication is repeated wirelessly in order with a time interval. That is, after performing wireless communication (1) between the distal end wireless device main bodies 4A at time (t ₁ ) and turning off the communication for a certain time, the wireless communication between the distal wireless device main body 4A and the intermediate wireless device main body 4B ₁ is performed. Communication (2) is performed at time (t ₂ ). Then, the radio communication of the intermediate part radio device body 4B ₁ and the intermediate part radio device body 4B ₂ a (3) at time _{(t 3).} Furthermore, after the communication is turned OFF for a certain time, the wireless communication (1) between the distal end wireless device main body 4A and each other is performed again at time (t ₄ ), and the same pattern is repeated thereafter.

FIG. 5 shows a wireless communication method in the case where the wireless device main body 4 is provided at the distal end portion 12 and the intermediate portion 13 of the shut-off can 3a and the peripheral portion 11 of the shut-off can 3a. FIG. 5A shows the arrangement of the wireless device main bodies 4, and FIG. 5B shows the wireless communication between the wireless device main bodies 4 in a time chart. In FIG. 5B, the horizontal axis indicates time (t), the vertical axis indicates communication strength (p), the value when wireless communication is OFF is “α”, and the wireless communication is ON. The value is “β”. The blocking cans 3a, the tip portion radios body 4A, an intermediate portion radio device body 4B ₁ and 4B ₂ is provided. When the shut-off can 3a is lifted up, the shut-off can peripheral portion 11 is provided with peripheral radio main units 4C ₁ , 4C ₂ , 4C _{3 at} positions corresponding to the radio main units 4. As shown in FIG. 5B, each wireless communication is repeated wirelessly in order with a time interval. That is, after performing wireless communication (1) between the distal end wireless device main body 4A and the peripheral wireless device main body 4C ₁ at time (t ₁ ) and turning off the communication for a certain time, the intermediate wireless device main body 4B ₁ and Wireless communication (2) of the peripheral wireless device main body 4C ₂ is performed at time (t ₂ ). Then, the radio communication of the intermediate part radio device body 4B ₂ and the peripheral part radio device body 4C ₃ a (3) at time _{(t 3).} Further, after the OFF communication for a predetermined time, it performed again at tip wireless device body 4A and the peripheral portion radios body 4C ₁ and radio communication (1) the time (t _4), repeated the same pattern follows It is.

  As shown in FIG. 4 and FIG. 5, the intermittent transmission and reception operations of the wireless device main body 4 can reduce the overall time for transmitting and receiving wireless signals, thereby saving power. Further, although communication is not established unless the timings of the transmitting side and the receiving side are matched, the certainty of communication can be ensured by adjusting the transmission / reception timing by the radio control unit 5. Furthermore, since transmission / reception is intermittent, even if devices having the same frequency operate during transmission / reception, the transmission / reception is hardly affected.

(Power supply system)
FIG. 6 shows the relationship between the radio main bodies 4A, 4B ₁ and 4B ₂ installed inside the shut-off can 3 and the power supply unit 9 shown in FIG. The radio main bodies 4A, 4B ₁ , 4B ₂ provided on the shut-off can 3 can be attached to the outer periphery of the shut-off can 3 by, for example, adhesion or band.
