Description

Technical Field

[0001] The embodiments in this specification relate to the field of safety monitoring, and in particular, to a housing and a method and apparatus for monitoring the integrity of the housing surface. Background Technology

[0002] Whether it's a safe, a cash transport box, or an ATM cabinet, these containers all serve the purpose of storing valuables, and therefore are generally equipped with anti-hijacking features. Taking cash transport boxes as an example, they possess many anti-hijacking functions, such as automatic alarm activation and automatic heating after a hijacking. However, in current technology, the alarm condition for a cash transport box is the detachment of the security device. If the cash transport box is directly damaged from the surface, the alarm condition will not be met, rendering the anti-hijacking function ineffective.

[0003] Therefore, there is an urgent need for a method to monitor the surface integrity of the enclosure, thereby ensuring financial security. Summary of the Invention

[0004] The purpose of the embodiments in this specification is to provide a box and a method and apparatus for monitoring the surface integrity of the box, so as to monitor the surface integrity of the box and ensure financial security.

[0005] To achieve the above objectives, one embodiment of this specification provides a method for monitoring the integrity of a housing surface. The inner surface of the housing is provided with a light path, and a first transmitting-receiving composite component and a second transmitting-receiving composite component are respectively disposed at both ends of the light path. The method includes:

[0006] After the first transmitting and receiving composite unit transmits an optical signal, the first transmitting and receiving composite unit and the second transmitting and receiving composite unit alternately transmit optical signals according to the reception status of the second transmitting and receiving composite unit.

[0007] By combining the reception status of the first transmit-receive composite component and the reception status of the second transmit-receive composite component, the integrity of the enclosure surface is monitored.

[0008] Preferably, the light path is arranged between the two furthest sides on the inner surface of each plane of the housing.

[0009] Preferably, the light path is arranged in a loop or serpentine shape between the two furthest sides on the inner surface of each plane of the housing.

[0010] Preferably, the material of the optical path is acrylic resin, polycarbonate, epoxy resin or glass.

[0011] Preferably, the receiving status further includes:

[0012] The attenuation value of the optical signal received by the second transmitter-receiver composite is greater than the attenuation threshold, or the second transmitter-receiver composite fails to receive an optical signal for a set number of consecutive times.

[0013] Preferably, the monitoring of the integrity of the enclosure surface, combining the reception of the emitted optical signal by the first transmit-receive composite component and the reception of the emitted optical signal by the second transmit-receive composite component, further includes:

[0014] After the first transmitting and receiving composite unit transmits an optical signal, the first transmitting and receiving composite unit receives the optical signal, and the first transmission time of the optical signal is obtained based on the transmission time and reception time of the first transmitting and receiving composite unit.

[0015] After the second transmitting and receiving composite unit transmits an optical signal, the second transmitting and receiving composite unit receives the optical signal. Based on the transmission time and reception time of the second transmitting and receiving composite unit, the second transmission time of the optical signal is obtained.

[0016] The cross-section of the enclosure is calculated based on the first transmission time and the second transmission time to monitor the integrity of the enclosure surface.

[0017] Preferably, the step of calculating the cross-section of the enclosure based on the first transmission time and the second transmission time to monitor the integrity of the enclosure further includes:

[0018] Based on the first transmission time, the first optical path length from the first transmit-receive composite to the cross-section is calculated;

[0019] Based on the second transmission time, the second optical path length from the second transmit-receive composite to the cross-section is calculated;

[0020] The number of cross-sections of the enclosure is calculated based on the length of the first optical path and the length of the second optical path to monitor the integrity of the enclosure surface.

[0021] Preferably, calculating the first optical path length from the first transmit-receive composite to the cross-section based on the first transmission time further includes:

[0022] The length of the first optical path is calculated using the following formula:

[0023] s1 = t1v / 2;

[0024] Where s1 is the first optical path length, t1 is the first transmission time, and v is the propagation speed of the optical signal in the optical path;

[0025] The calculation of the second optical path length from the second transmit-receive composite to the cross-section based on the second transmission time further includes:

[0026] The length of the second optical path is calculated using the following formula:

[0027] s2 = t2v / 2;

[0028] Where s2 is the second optical path length, t2 is the second transmission time, and v is the propagation speed of the optical signal in the optical path.

[0029] Preferably, the step of calculating the number of cross-sections of the enclosure based on the first optical path length and the second optical path length to monitor the integrity of the enclosure further includes:

[0030] Summing the lengths of the first and second optical paths yields the total length.

[0031] If the total length is greater than the upper limit of the length, then the box has a cross section;

[0032] If the total length is less than the lower limit of the length, then the box has more than one cross-section.

[0033] Preferred options also include:

[0034] After the first transmit-receive composite unit transmits an optical signal, the second transmit-receive composite unit receives the optical signal. Based on the transmission time of the first transmit-receive composite unit and the reception time of the second transmit-receive composite unit, the third transmission time of the optical signal is obtained.

[0035] If the third transmission time is not within the preset time range, then when the first transmit-receive composite unit transmits the optical signal again, the first transmit-receive composite unit and the second transmit-receive composite unit jointly receive the optical signal to monitor the integrity of the box surface.

[0036] Preferably, after the first transmit-receive composite element transmits an optical signal again, the first transmit-receive composite element and the second transmit-receive composite element jointly receive the optical signal to monitor the integrity of the enclosure surface, and then the process further includes:

[0037] If the first transmitter-receiver composite receives an optical signal, or the attenuation value of the optical signal received by the second transmitter-receiver composite is greater than the attenuation threshold, or the second transmitter-receiver composite fails to receive an optical signal for a set number of consecutive times, then the two transmitter-receiver composites alternately transmit optical signals, and the integrity of the enclosure surface is monitored by combining the reception status of the two transmitter-receiver composites.

[0038] On the other hand, embodiments of this specification provide a device for monitoring the integrity of a box surface. The inner surface of the box is provided with a light path, and a first transmitting-receiving composite component and a second transmitting-receiving composite component are respectively disposed at both ends of the light path. The device includes:

[0039] The transmitting and receiving module is used to allow the first transmitting and receiving composite to transmit optical signals alternately, based on the receiving status of the second transmitting and receiving composite, after the first transmitting and receiving composite transmits an optical signal;

[0040] The monitoring module is used to monitor the integrity of the housing surface by combining the reception status of the first transmit-receive composite component and the reception status of the second transmit-receive composite component.

[0073] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the embodiments of this specification.

[0074] Whether it's a safe, a cash transport box, or an ATM cabinet, these containers all serve the purpose of storing valuables, and therefore are generally equipped with anti-hijacking features. Taking cash transport boxes as an example, they possess many anti-hijacking functions, such as automatic alarm activation and automatic heating after a hijacking. However, in current technology, the alarm condition for a cash transport box is the detachment of the security device. If the cash transport box is directly damaged from the surface, the alarm condition will not be met, rendering the anti-hijacking function ineffective.

[0075] To address the aforementioned issues, this specification provides a method for monitoring the integrity of a housing surface. Figure 1 This is a flowchart illustrating a method for monitoring the integrity of a housing surface provided in an embodiment of this specification.

In actual system or device products, the methods shown in the embodiment or drawings can be executed sequentially or in parallel.

[0076] It should be noted that the terms "first," "second," etc., in the description, claims, and accompanying drawings of the embodiments in this specification are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, apparatus, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0077] Reference Figure 1 This specification discloses a method for monitoring the integrity of a box surface, wherein an optical path is provided on the inner surface of the box, and a first transmitting-receiving composite component and a second transmitting-receiving composite component are respectively provided at both ends of the optical path, and the method includes:

[0078] S101: After the first transmitting and receiving composite unit transmits an optical signal, the first transmitting and receiving composite unit and the second transmitting and receiving composite unit alternately transmit optical signals according to the reception status of the second transmitting and receiving composite unit.

[0079] S102: By combining the reception status of the first transmitting and receiving composite component and the reception status of the second transmitting and receiving composite component, the integrity of the enclosure surface is monitored.

[0080] The enclosure can be a safe, cash box, or ATM cabinet for storing valuables, etc. The enclosure can be a polyhedron, octahedron, or other easily conceivable shape, such as a cylinder, frustum, or sphere. The light path is positioned between the two furthest edges on the inner surface of each plane of the enclosure, as shown in the reference diagram. Figure 2 and Figure 3 Specifically, it is arranged in a spiral or serpentine shape, and the material of the optical path is acrylic resin, polycarbonate, epoxy resin or glass.

[0081] A first transmit-receive composite and a second transmit-receive composite are respectively provided at both ends of the optical path. The first transmit-receive composite can be provided at the beginning of the optical path and the second transmit-receive composite at the end of the optical path, or the second transmit-receive composite can be provided at the beginning of the optical path and the first transmit-receive composite at the end of the optical path. Both the first transmit-receive composite and the second transmit-receive composite have both transmit and receive functions. After the first transmit-receive composite or the second transmit-receive composite transmits an optical signal, the first transmit-receive composite can receive it and the second transmit-receive composite can also receive it.

[0082] Reference Figure 4 Taking a hexahedron as an example, a typical enclosure includes a cover plane and an enclosure body. One end of the cover plane is hinged to the enclosure body, and the other end of the cover can be opened. Items are retrieved or placed by opening and closing the cover plane. Generally, two adjacent planes in the enclosure body are fixedly connected, and the corresponding light paths on the inner surfaces of the two adjacent planes are directly connected. However, since the cover plane needs to be opened and closed, it is not suitable for direct connection of light paths. Connectors are provided between the cover plane and its adjacent planes, and light guide lenses are provided at the connectors to bridge the optical signals in the light paths of the cover plane / adjacent plane to the light paths of the adjacent plane / cover plane. Through the above connection method, the light path structure inside the enclosure is stabilized, ensuring the normal transmission of optical signals.

[0083] Generally, the first transmitter-receiver composite unit emits an optical signal once every set time interval. When the first transmitter-receiver composite unit emits an optical signal, if the enclosure is intact and has not suffered any external damage such as impact, pressure or squeezing, only the second transmitter-receiver composite unit can receive the optical signal emitted by the first transmitter-receiver composite unit. Therefore, in order to save energy, the first transmitter-receiver composite unit can be turned on to emit an optical signal and its receiving function can be turned off, while the second transmitter-receiver composite unit can be turned on to receive an optical signal and its emitting function can be turned off.

[0084] However, when the enclosure is incomplete, with one or more planes having a break, the second transmit-receive composite unit will be unable to receive or can only receive a very small amount of optical signal. In this case, it is necessary to activate the receiving function of the first transmit-receive composite unit and the transmitting function of the second transmit-receive composite unit, so that the first and second transmit-receive composite units alternately transmit optical signals. Specifically, the receiving status of the second transmit-receive composite unit is as follows: if the attenuation value of the optical signal received by the second transmit-receive composite unit is greater than the attenuation threshold, or if the second transmit-receive composite unit fails to receive an optical signal for a set number of consecutive times, then the first and second transmit-receive composite units alternately transmit optical signals.

[0085] The attenuation threshold is calculated as the constant attenuation of the optical signal during transmission when the enclosure is in normal condition (i.e., intact and without any external damage such as impact, pressure, or compression), and the optical path is undamaged. The set number of consecutive times the optical signal is not received can be determined based on actual operating conditions. When alternating optical signal transmission, one transmits first, followed by the other, and both transmit at the same frequency to avoid optical interference caused by two optical signals existing simultaneously in the optical path.

[0086] When a cross-section appears in the enclosure, the first transmitter-receiver composite can receive the optical signal emitted by itself, and the second transmitter-receiver composite can receive the optical signal emitted by itself. This is because when a cross-section appears in the enclosure, a break appears in the optical path at the corresponding location. The optical signal is reflected back at the break point, returning to its origin. Assuming the first transmitter-receiver composite emits an optical signal, it returns after encountering the break point and is received by the first transmitter-receiver composite; similarly, the second transmitter-receiver composite emits an optical signal, which also returns after encountering the break point and is received by the second transmitter-receiver composite. The number of cross-sections in the enclosure can be determined by the transmission length of the optical signal during this process.

[0087] Specifically, refer to Figure 5 The monitoring of the integrity of the enclosure surface, based on the combined reception of the first transmit-receive composite component and the second transmit-receive composite component, further includes:

[0088] S201: After the first transmitting and receiving composite unit transmits an optical signal, the first transmitting and receiving composite unit receives the optical signal, and the first transmission time of the optical signal is obtained according to the transmission time and reception time of the first transmitting and receiving composite unit.

[0089] S202: After the second transmitting and receiving composite unit transmits an optical signal, the second transmitting and receiving composite unit receives the optical signal, and the second transmission time of the optical signal is obtained according to the transmission time and reception time of the second transmitting and receiving composite unit.

[0090] S203: Calculate the cross-section of the enclosure based on the first transmission time and the second transmission time to monitor the integrity of the enclosure surface.

[0091] Taking the first transmit-receive composite as an example, assuming the time when the first transmit-receive composite transmits the optical signal is T1 and the time when it receives the optical signal is T2, then the first transmission time of the optical signal is T2-T1. Similarly, the second transmission time of the optical signal can also be calculated. It should be noted that both the first and second transmission times are twice the distance from the first or second transmit-receive composite to the cross-section, because this includes the round-trip distance of the optical signal from the transmit-receive composite to the cross-section and back to the transmit-receive composite.

[0092] Furthermore, refer to Figure 6 The step of calculating the cross-section of the enclosure based on the first transmission time and the second transmission time to monitor the integrity of the enclosure further includes:

[0093] S301: Calculate the first optical path length from the first transmit-receive composite to the cross-section based on the first transmission time;

[0094] S302: Calculate the second optical path length from the second transmit-receive composite to the cross-section based on the second transmission time;

[0095] S303: Calculate the number of cross-sections of the enclosure based on the length of the first optical path and the length of the second optical path, in order to monitor the integrity of the enclosure surface.

[0096] The length of the first optical path is calculated using the following formula:

[0097] s1 = t1v / 2;

[0098] Where s1 is the first optical path length, t1 is the first transmission time, and v is the propagation speed of the optical signal in the optical path;

[0099] The length of the second optical path is calculated using the following formula:

[0100] s2 = t2v / 2;

[0101] Where s2 is the second optical path length, t2 is the second transmission time, and v is the propagation speed of the optical signal in the optical path.

[0102] In the embodiments described in this specification, reference is made to Figure 7 The step of calculating the number of cross-sections of the enclosure based on the first optical path length and the second optical path length to monitor the integrity of the enclosure further includes:

[0103] S401: Summ the length of the first optical path and the length of the second optical path to obtain the total length;

[0104] S402: If the total length is greater than the upper limit of the length, then the box has a cross section;

[0105] S403: If the total length is less than the lower limit of the length, then the box has more than one cross-section.

[0106] The upper and lower length limits are determined based on the actual layout length of the optical path. Assuming the actual layout length is M, if the total length is equal to M, it indicates only one cross-section, possibly just a crack. Therefore, the upper length limit can be set as a first multiple of M, less than 1 but close to 1, for example, 0.98 or 0.99. If the total length is much less than M, it indicates more than one cross-section, possibly forming a hole. Therefore, the lower length limit can be set as a second multiple of M, less than the first multiple, for example, 0.95 or 0.96.

[0107] If the total length is greater than or equal to the lower limit of length and less than or equal to the upper limit of length, there may be more than one cross-section. However, compared to the case where the total length is less than the lower limit of length, the intervals between the cross-sections are closer in this case, for example, a small hole may be formed.

[0108] In addition, the position of the cross-section can be calculated based on the length of the first or second optical path. The arrangement order of the optical paths on each surface of the housing is known. For example, the optical path passes through the bottom surface, left side surface, front side surface, cover plate plane, rear side surface, right side surface and back to the bottom surface. The actual layout length of the optical path is M, the length of the bottom surface is m1, the length of the left side surface is m2, the length of the front side surface is m3, the length of the cover plate plane is m4, and the length of the rear side surface is m5. After calculating the length of the first optical path s1, the distance between the cross-section and the first transmitting and receiving composite component can be obtained as s1. If s1 is less than m1, the cross-section is located on the bottom surface. If s1 is greater than m1 and less than m1+m2, the cross-section is located on the left side surface. The specific position of the cross-section can be obtained in this way.

[0109] Generally, the first and second transmitter-receiver composite units alternately transmit optical signals at regular intervals. For enclosures with a single cross-section, this allows for shorter transmission intervals and more frequent alternating transmissions, facilitating close monitoring. For enclosures with more than one cross-section, timely warnings should be issued to alert staff or users.

[0110] When the total length is greater than or equal to the lower limit and less than or equal to the upper limit, there is more than one cross-section, but the interval between two cross-sections is relatively close. The distance between cross-sections can be determined using the following method. (Refer to...) Figure 3 Taking a serpentine setup as an example, when setting up a serpentine setup, you need to start from one end, first arrange a light path of a set length along the y-axis, then bend it along the x-axis for a while, arrange a light path of the same set length along the y-axis, then bend it along the x-axis for a while, and so on until the other end.

[0111] If a cross section exists on a certain surface, then all cross sections on that surface conform to the following relationship:

[0112]

[0113] Where x represents the total length of the optical path between the cross-section and the starting point of the surface (the starting point is the position where the optical pulse emitted by the first transmitting and receiving composite first arrives at the surface), x0 is the distance between the cross-section and the starting point of the surface along the x-axis, k is the length of the cross-section at the kth bend of the surface, and w is the set length along the y-axis; the value of k can be calculated using the above formula.

[0114] If there are two cross-sections, the k-value can be calculated using the same method as above, taking the position where the light pulse emitted by the second transmitting and receiving composite first arrives at that surface as the starting point. If the difference between the two k-values ​​is within a threshold, the interval between the two cross-sections can be considered to be relatively close. The threshold can be set according to the actual situation, for example, it can be 1.

[0115] In the embodiments described in this specification, reference is made to Figure 8 It also includes:

[0116] S501: After the first transmitting and receiving composite unit transmits an optical signal, the second transmitting and receiving composite unit receives the optical signal. Based on the transmission time of the first transmitting and receiving composite unit and the reception time of the second transmitting and receiving composite unit, the third transmission time of the optical signal is obtained.

[0117] S502: If the third transmission time is not within the preset time range, then when the first transmit-receive composite unit transmits the optical signal again, the first transmit-receive composite unit and the second transmit-receive composite unit jointly receive the optical signal to monitor the integrity of the box surface.

[0118] The preset time range refers to the time difference between the light signal emitted by the first transmitter-receiver composite component and the light signal received by the second transmitter-receiver composite component when the enclosure is intact and has not suffered any external damage such as impact, heavy pressure or squeezing. Assuming that the time for the first transmitter-receiver composite component to emit the light signal is T3 and the time for the second transmitter-receiver composite component to receive the light signal is T4, then the time difference is T4-T3. The preset time range is obtained by calculating the time difference multiple times using this method.

[0119] In practical applications, after the first transmitter-receiver composite unit transmits the optical signal in step S101, the second transmitter-receiver composite unit receives the optical signal. The time difference between the two units is then calculated to obtain the third transmission time of the optical signal. If the enclosure is in a normal state, the third transmission time is within a preset time range. If it is not within the preset time range, it indicates that the enclosure is in an abnormal state. However, if the second transmitter-receiver composite unit can still receive the optical signal and the attenuation value of the optical signal is not greater than the attenuation threshold, it means that the enclosure has not yet developed a cross-section. Instead, it may be due to heavy pressure causing the optical path to be stretched, or compression causing the optical path to be compressed, thus causing the third transmission time to be outside the preset time range. At this point, the receiving function of the first transmitter-receiver composite unit is activated. Both the first and second transmitter-receiver composite units jointly receive the optical signal to monitor the integrity of the enclosure surface and to promptly confirm whether the enclosure has developed a cross-section, because a cross-section of the enclosure will always be accompanied by the first transmitter-receiver composite unit being able to receive the optical signal.

[0120] In this embodiment of the specification, after the first transmit-receive composite element transmits an optical signal again, the first transmit-receive composite element and the second transmit-receive composite element jointly receive the optical signal to monitor the integrity of the enclosure surface, and then the following is further included:

[0121] If the first transmitter-receiver composite receives an optical signal, or the attenuation value of the optical signal received by the second transmitter-receiver composite is greater than the attenuation threshold, or the second transmitter-receiver composite fails to receive an optical signal for a set number of consecutive times, then the two transmitter-receiver composites alternately transmit optical signals, and the integrity of the enclosure surface is monitored by combining the reception status of the two transmitter-receiver composites.

[0122] If the first transmitter-receiver composite receives an optical signal, or the attenuation value of the optical signal received by the second transmitter-receiver composite is greater than the attenuation threshold, or the second transmitter-receiver composite fails to receive an optical signal for a set number of consecutive times, it indicates that a cross-section has occurred in the enclosure. At this time, as described in S101 and S102, the first transmitter-receiver composite and the second transmitter-receiver composite alternately transmit optical signals to further monitor the integrity of the enclosure surface.

[0123] If none of the above situations occur consecutively, the receiving function of the first transmitter-receiver composite unit will be turned off to save energy consumption, because long-term monitoring shows that the enclosure is unlikely to develop a cross section at this time.

[0124] The method described in this specification involves arranging optical channels within the enclosure and employing the coordinated transmission and reception functions of the first and second transmission and reception composite components to monitor the integrity of the enclosure surface. Different measures are taken for different reception conditions, improving the efficiency and accuracy of monitoring and thus ensuring financial security.

[0125] Based on the method for monitoring the surface integrity of a enclosure described above, this specification also provides a device for monitoring the surface integrity of an enclosure. The device may include a system (including a distributed system), software (application), module, component, server, client, etc., using the method described in this specification, combined with necessary hardware implementation. Based on the same innovative concept, the devices in one or more embodiments provided in this specification are as described in the following embodiments. Since the implementation schemes and methods for solving the problem are similar, the implementation of specific devices in this specification can refer to the implementation of the aforementioned method, and repeated details will not be repeated. As used below, the terms "unit" or "module" can refer to a combination of software and / or hardware that performs a predetermined function.
