Also effect preferably can be obtained when the equipment that the technical program is very fast to travelling speed, the position is higher, volume is bigger is monitored, and remote monitoring can be realized equipment.
For the ease of the clear technical scheme of describing the embodiment of the invention, in inventive embodiment, adopted printed words such as " first ", " second " that function is distinguished with essentially identical identical entry of effect or similar item, it will be appreciated by those skilled in the art that printed words such as " first ", " second " do not limit quantity and execution order.
Embodiment four
The mechanical hook-up that has RFID reliability monitoring system that the embodiment of the invention four is provided is described below.Be that example describes to choose bolt as mechanical hook-up situation to be monitored in the embodiment of the invention four.Consider that bolt all is a kind of requisite element in a large amount of equipment, and bolt also is a kind of element that very easily produces distortion in the equipment, higher with the correlation degree of device security, bolt is connected mutually as element to be monitored and with RFID label after improving, forming a kind of breaker bolt, is a kind of more rational monitoring scheme.
Referring to Fig. 4, shown schematic vertical view when a kind of employing RFID reliability monitoring system monitors bolt.The RFID label comprises chip 1 (RFID chip) and the antenna element 2 that is made into integration, and has at least one easily broken zone (shown in the zone 3,4 that has slash mark among the figure) on the described antenna element 2, and when fracture took place in easily broken zone, the RFID label lost efficacy.Because RFID chip 1 and antenna element 2 are one, promptly both coil lines are communicated with, and rupture when easily broken zone, and when promptly opening circuit appearred in antenna element 2, opening circuit appearred in entire RF ID label, and this RFID label lost efficacy.
The reason that fracture takes place in above-mentioned easily broken zone mainly be bolt taken place distortion (as damaged, rupture, get loose, conquassation) or move, this distortion or move and applied an external force to antenna element causes easily broken zone and ruptures.Can by cut on the antenna element or punching after form easily broken zone, have line tooth or hole tooth on this easily broken zone.Promptly, under the situation that does not influence the coil operate as normal, dash and wear or cut some perforations,, the concrete shape of line tooth or hole tooth is not limited so that this presumptive area ruptures easily in the presumptive area of antenna element.
Further, the antenna element of described RFID label is set to the strip parts, this processing mode, consideration is when being subjected to external force, the strip parts are relatively more responsive to the effect of power, even the distortion of bolt or mobile slighter also can monitor this distortion or mobile phenomenon.By thickness and the width of controlling these strip parts, can adjust the sensitivity of strip parts to external force, thus the distortion of the bolt that control can monitor or mobile degree.Under this scene, above-mentioned easily broken zone can be set to be parallel to the zone of strip component width direction, and easily broken zone can connect on strip component width direction, also can not connect.
Be appreciated that when needs, when to a certain degree just reporting to the police, also can antenna element be set to the parts of other shapes (as triangle), to have the ability of bearing certain external force as allowing bolt to be deformed to.
Further, above-mentioned strip parts are the uniform rectangle of thickness, and promptly the thickness of strip parts is even, and are the shape of parallel lines on two relative long limits of length direction.Under this scene, the cross section of above-mentioned strip parts is of similar shape, and wherein, this cross section is for to block the resulting cross section of strip parts along the length direction perpendicular to above-mentioned strip parts.This processing mode, can further improve antenna element with and on easily broken zone to the susceptibility of external force, detect the slighter distortion of bolt, in time fix a breakdown, guarantee device security.
The control point of choosing bolt is the head of bolt, and adopts the connected mode of welding described antenna element to be welded on the head of bolt, so that easily broken zone is fixed on the bolt.
Further, it is also conceivable that contingent distortion or the situation of movement of bolt when choosing the control point that distortion occurs easily on the bolt or move at actual scene, for example, when bolt is easy to move up and down, the control point of choosing bolt is the surface area of bolt head, described antenna element is welded on the surface area of bolt head; Perhaps, when bolt is easy to twisting takes place, the control point of choosing bolt is the side regions of bolt head, referring to Fig. 4, shown the scene that described antenna element is welded on the side regions of bolt head, antenna element 2 is welded on the side regions of bolt 8 heads by pad 7 with antenna element 2, so that easily broken zone is fixed on the bolt.
Further, referring to Fig. 1, described antenna element has first easily broken regional 3, above-mentioned first easily broken regional 3 pre-position that is positioned on the antenna element 2 near bolt 8 one sides.Because first easily broken regional 3 the position is nearer apart from bolt 8, bolt 8 distortion or the external force that produces when mobile make easily broken regional 3 to rupture easily, thereby accurately and timely detect fault.Except this first easily broken zone, can also have other easily broken zone on the antenna element, be used for the distortion of miscellaneous part is monitored.
Optionally, for above-mentioned antenna element 2 is provided with second easily broken regional 4, above-mentioned second easily broken regional 4 is positioned at the pre-position of close RFID tag body 1 one sides on the antenna element 2, utilizes the distortion or mobile monitoring of miscellaneous part in second easily broken regional 4 pairs of RFID tag body 1 or the RFID label.
Be appreciated that when only being provided with second easily broken regionally 4 the time, utilize second easily broken regional 4 also can monitor bolt.
Further, can also annex 5 be set, fixture 6 is set on annex 5, be used for the RFID label is fixed on equipment (or mechanical hook-up), keep the stable of RFID label for the RFID label.The working method of annex 5 can be referring to second support bar 9 among Fig. 6 among Fig. 4.
