Description

Method and device for protecting personal safety or property safety

Technical field

The present invention relates to the field of security technologies, and more particularly to a method and apparatus for securing security or property security. Background technique

On the one hand, modern society emphasizes the protection of personal safety, on the other hand, it also attaches importance to the protection of property security. Personal safety covers the safety of the child and the children, the elderly, the disabled, etc. Any person is in fact facing different risks anytime, anywhere, such as violent attacks or robberies, kidnappings, abductions, etc. The scope of property security protection here includes not only the measurable physical property, but also the invaluable data, pets, etc. It is obvious that these things are always facing risks such as theft and loss.

The prior art discloses a personal safety protection system (Chinese patent application number:

01144614.5 ) , comprising a communication network, a user terminal and a computer information platform connected to the communication network, an alarm processing center, and an alarm line connected to the computer information platform and the alarm processing center; the user terminal comprises a wired sensor and a wireless sensor transmitter a wireless sensor receiver, a trigger driving circuit connected to the wired sensor and the wireless sensor receiver, and a wireless pager and a wired pager connected to the trigger driving circuit, wherein the user terminal is generally a landline or a mobile phone, and the wireless sensor And wired sensors use sensory alarms that provide switching quantities, for example, with speech recognition, point-frequency voice-activated sensors, infrared sensors with infrared coupling, proximity sensors with capacitive or electromagnetic induction, and contact sensors with proximity switches.

The above technical solutions have the following problems in practical application:

1. In the above solution, the existing communication network needs to be used for alarming. The user terminal can be a landline or a mobile phone, but the existing communication network needs to be modified;

2. In the above scheme, the alarm function and form are single. After receiving the alarm, the cause of the safety accident cannot be accurately determined, so that the corresponding safety accident handling strategy can be adopted, and the subsequent alarm function is not convenient.

Third, the personal safety guarantee in the above schemes requires the construction of a special communication network alarm through the basis of the alarm to the alarm center. The application range is narrow, which is not conducive to people's daily life application. In addition, the patent application of US Publication No. US2007/0205895A1 also discloses an anti-theft system and a child protection system (Pick Pocket Protection, Theft Prevention System, and Child Protection System), the system disclosed in the patent application includes at least one Radio frequency identification tag ("radio frequency tag" or "RFID Tag") and at least one speaker connected to the alarm ("alarm")

("speaker") radio frequency identification reader, the function of the radio frequency identification reader is as a two-way polating device or interrogator ("two-way pol l ing device or interrogator"), every certain time Transmitting a radio frequency wave signal, inquiring whether the above radio frequency identification tag exists, and then receiving a radio frequency wave signal (including an identification code of the radio frequency identification tag) transmitted by the radio frequency identification tag to answer the inquiry, and receiving or receiving the radio frequency wave signal strength or receiving The time required for the radio frequency wave signal (ie, the time delay of transmitting the radio frequency wave signal compared to the inquiry) to determine the distance between the location of the radio frequency identification tag and the two-way interrogation device, if the distance is greater than a predetermined upper limit

("preset l imit " ) distance, that is, the received RF signal strength is less than a preset lower limit strength or the time required to receive the RF signal is greater than a preset upper limit time, the above alarm speaker will sound Prompt, on the other hand, if the RFID tag and the I or RFID reader are brought close together until the distance between the two is less than a preset reset distance, the alarm speaker will stop sounding.

However, the above-mentioned technologies have the following disadvantages in practical application and feasibility: 1. The above solution relates to a portable radio frequency identification reader. However, under the existing technical conditions, the portable radio frequency identification reader has a reading distance of at most about 10 cm based on limited battery power, which means that the preset upper limit distance can be only 10 cm at the maximum. Therefore, the above solution can only effectively ensure that the protected target is within 10 cm of the user's distance. If the protected target is slightly more than 10 cm away from the user due to daily activities, operations, etc., the audible prompt will be triggered, that is, the error is erroneous. Being stolen for protected targets, etc. And 10 cm is probably equal to the width of the palm of a typical adult, so this kind of protection is of little significance in practical applications.

In addition, with the miniaturization of electronic technology, general application electronic devices emphasize the reduction in size and weight, so that they can be "portable" for placement or installation on mobile devices (eg, vehicles), even with them. Carrying, thereby greatly increasing the application range and commercial value of the electronic device. However, as noted above, since the practically applicable distance is small, the above-disclosed scheme cannot coexist between the practical application meaning and the "portability". 2. The above-mentioned disclosed schemes have a function of singularity, protection is not comprehensive, and there is no expansion in function. In simple terms, it only ensures that the protected target is within the preset upper limit of the user's preset limit. If the upper limit is exceeded, an audible prompt will sound. In other words, the user can only ensure the existence of the protected target, but does not know about other security incidents related to the protected target, such as: whether to fall, lying down, etc. Moreover, there is no room for expansion beyond this single and incomplete function.

Third, due to the lack of data protection in the above-mentioned publicly available solutions, it is not difficult to deliberately crack the protection function, thereby causing kidnapping, abduction, theft, and the like. For example: an accomplice of a kidnapper, a thief, etc. can temporarily put an interfering electronic device on the radio frequency identification reader, and the device is used to read the radio wave signal transmitted by the radio frequency tag when answering the inquiry and the identification thereof. Code, and then continuously emulates and transmits the radio signal to answer the inquiry after the RFID reader, spoofing the RFID reader so that it continuously transmits the radio frequency identification tag to be transmitted when answering the inquiry The radio frequency signal, so that the alarm speaker connected to the above RFID reader will not give an audible prompt, and the other partner can tie away, abduct, steal, etc. the protected target. After the protected target is far away, even if the previous accomplices removed the above-mentioned interfering electronic device, the alarm speaker will sound a prompt, but it is too late for the user to chase after

The communication sub-module 12 in the module 1 is directly notified by the communication sub-module 32 in the above-mentioned security protection module 3 or by the above or this The communication sub-module 21 of the independent communication modules 2 indirectly informs that the item or the preset security incidents occur in the security protection module 3 described above, and the communication sub-module 12 in the central coordination module 1 signals the central coordination module. The user interface sub-module 11 of 1 occurs with respect to the item or the preset security incidents in the security protection module 3 described above, and the user interface sub-module 11 in the central coordination module 1 informs the user through the connected input/output device. The item or the preset security incidents occur in the security protection module 3 described above, and the user interface sub-module 11 in the central coordination module 1 may also, but not necessarily, be connected according to the security incident database 13 in the central coordination module 1 and through the connection. The input I output device informs the user of the information related to the item or the preset safety accident that has occurred. It should be noted that the foregoing radio wave signal may be based on a wireless personal area network or a network transmission protocol other than a personal area network. When implemented, for example, it may be, but not necessarily, based on a wireless personal area network based on a ZigBee network transmission protocol. In addition, the minimum zero detecting circuit 33 connected to the detecting interface sub-module 31 in the above-mentioned security protection module 3 in this embodiment may include, but is not limited to, an accelerometer circuit, a heatoresistor circuit, and a thermal circuit. Thermistor circuit, etc., these detection circuits 33 can be used to detect the occurrence of a preset safety accident, for example: The accelerometer circuit can detect whether the protected target is tapped, that is, the protected person Whether the target may fall or be violently attacked or robbed, etc.; the photosensitive circuit can detect whether the protected target is exposed to excessive light, that is, whether the protected property target may be opened by the thief, etc.; the thermal circuit can detect Whether the protected target is overheated means that the protected target is likely to be exposed to the sun; the wet control circuit can detect whether the protected target is wet by excessive water, which means that the protected target may be drowned or protected. Whether children or elderly targets may be wet, etc.; other detection The function of circuit 33 can also be analogized. The above independent communication module 2 is optional in this embodiment. When it exists, the sole function of the independent communication module 2 is that its communication sub-module 21 can assist the communication sub-module 12 in the central coordination module 1 to receive the transmission by the communication sub-module 32 in the security protection module 3. a radio wave signal, once the communication sub-module 21 in one or some of the independent communication modules 2 receives the radio wave signal, and the intensity of the received radio wave signal is greater than a preset lower limit intensity m, the one or the The communication sub-module 21 in the independent communication module 2 forwards the radio wave signal to the communication sub-module 12 in the central coordination module 1, and informs the communication sub-module 12 in the central coordination module 1 about the original The content of the radio wave signal is received by the communication sub-module 21 in the one or the independent communication modules 2, and as a result, the communication sub-module 12 in the central coordination module 1 directly receives the communication device in the security protection module 3 described above. The radio wave signal transmitted by module 32. Therefore, the independent communication module 2 becomes particularly useful whenever there is a transmission obstacle of the radio wave signal between the central coordination module 1 and the security protection module 3 (for example, by a metal object). The communication sub-module 32 in the above-mentioned security protection module 3 often needs to transmit radio wave signals to and from the communication sub-modules 12 and I in the central coordination module 1 or the communication sub-modules 21 in the respective independent communication modules 2, in order to identify each radio. Which wave signal is transmitted by the communication sub-module 32 in the security protection module 3 or which communication protection module 32 in the security protection module 3 should be received by each of the security protection modules 3 The radio wave signal transmitted by the communication sub-module 32, the content of which contains a preset unique identification code of the security protection module 3, and also each radio wave that should be received by the communication sub-module 32 in a certain security protection module 3. a signal, the content of which includes a preset unique identification code of the security protection module 3, if the radio wave signal is based on a wireless personal area network based on the Z _lg Bee network transmission protocol, one of the foregoing security protection modules 3 The preset unique identifier may be, but is not necessarily, the internet protocol address of the security protection module 3 (internet protocol address or simple Called IP address ). In the above embodiment, the communication sub-module 32 in the security protection module 3 intermittently transmits radio wave signals to the communication sub-modules 12 and I in the central coordination module 1 or the communication sub-modules 21 in the respective independent communication modules 2, One function is to keep the communication sub-modules at both ends of the above transmission in communication state. In fact, in actual design and application, the security protection module 3 together with its power supply is not necessarily but independently placed on the protected target, so On the one hand, the size of the security protection module 3 together with its power supply is generally small, which means that the power supply capacity is limited, and on the other hand, the power supply is difficult to borrow from other electronic devices such as mobile phones, electronic PDAs, etc., thereby reducing the power supply of the security protection module 3. Consumption is required to extend the operating time after each charging or replacement of the power supply; in addition, although the radio wave signal transmitted by the security protection module 3 (for example, but not necessarily based on the ZigBee network transmission protocol), There is no evidence at the international level that the power level is harmful to the human body, but if it is protected Personal target, then try to reduce the protected target's exposure to the radio wave signal transmitted by the security protection module 3 within a short distance, and also help the user to use it with peace of mind. Therefore, other embodiments may be used for specific implementation, for example, for example. This embodiment is called "long-term mode" and is as follows: The communication sub-module 12 in the central coordination module 1 and the communication sub-module 21 in each independent communication module 2 respectively intermittently transmit radio wave signals to the communication sub-module 32 in each security protection module 3, if one or The communication sub-module 32 of some security protection modules 3 can not receive the radio wave signal or the intensity of the received radio wave signal within a predetermined upper limit period i _max ' It is less than a preset lower limit strength _m ', which means that one of the preset safety accidents has occurred in the safety protection module 3 or the above, and the preset safety accident means that the safety protection module 3 or the above is coordinated from the central coordination. The module 1 and all the independent communication modules 2 exceed a certain preset upper limit distance; the communication sub-module 32 in the above-mentioned one or more of the security protection modules 3 thus goes to the communication sub-modules 12 and I or the individual independent communication modules 2 in the central coordination module 1 The communication sub-module 21 in the transmission transmits another one or more strong radio wave signals (relative to the communication sub-module 12 in the central coordination module 1 described above) The radio wave signal transmitted by the communication sub-module 21 in the independent communication module 2 informs the communication sub-module 12 and the I in the central coordination module 1 or the communication sub-module 21 in each independent communication module 2 about the above preset. A security incident occurs in the security protection module 3 or the above. If the communication submodule 21 in any of the independent communication modules 2 receives the radio wave signal, the communication submodule 21 in the or each of the independent communication modules 2 is then directed to the center. The communication sub-module 12 in the coordination module 1 forwards the radio wave signal originally transmitted by the communication sub-module 32 in the security protection module 3, and informs the communication sub-module 12 in the central coordination module 1 about the one or the The communication sub-module 21 of the independent communication modules 2 also receives the radio wave signals transmitted by the communication sub-module 32 in the security protection module 3, and the communication sub-module 12 in the central coordination module 1 signals the central unit accordingly. The user interface sub-module 11 in the coordination module 1 relates to the above-mentioned default security accident in the above-mentioned security protection mode 3 occurs, that is, the protected target placed with the security protection module 3 or the above may have been kidnapped, abducted, stolen, lost, etc.; the user interface sub-module 11 in the central coordination module 1 passes through the connected input/output The device informs the user that the preset security incident occurs in the security protection module 3 or the above, and the user interface sub-module 11 in the central coordination module 1 may also, but not necessarily, be based on the security incident database 13 in the central coordination module 1 and The connected input/output device informs the user that it is helpful to respond to the information about the preset safety accident. And if this or these security protection modules 3 are brought closer to the central coordination module 1 and I or the independent communication module 2, the communication sub-module 32 in the security protection module 3 can receive the above-mentioned communication sub-modules 12 and I or the I in the central coordination module 1 within a preset upper limit period i _max ' The radio wave signal transmitted by the communication sub-module 21 in the independent communication module 2, and the intensity of the received radio wave signal or the signals is greater than a preset lower limit strength _m ', thus representing the safety or the like. The preset safety accident of the protection module 3 from the central coordination module 1 and all the independent communication modules 2 exceeding the preset upper limit distance no longer occurs in the security protection module 3 or the communication submodules in the security protection module 3 or the above. 32 thus transmitting another one or more radio wave signals to the communication sub-module 12 in the central coordination module 1 and/or the communication sub-module 21 in each individual communication module 2, thereby informing the communication sub-modules 12 and I in the central coordination module 1 Or the communication sub-module 21 in each of the independent communication modules 2 does not occur in the above-mentioned safety accident regarding the above-mentioned preset safety accident. Module 3, if the communication sub-module 21 in any of the independent communication modules 2 receives the above-mentioned radio wave signal, the communication sub-module 21 of the one or more independent communication modules 2 is then forwarded to the communication sub-module 12 in the central coordination module 1. The radio wave signal originally transmitted by the communication submodule 32 in the security protection module 3 is informed to the communication submodule 12 in the central coordination module 1 about the communication submodule in the or each of the independent communication modules 2. The radio wave signal transmitted by the communication sub-module 32 in the security protection module 3 is also received. The communication sub-module 12 in the central coordination module 1 thus signals the user interface sub-module 11 in the central coordination module 1. The above-mentioned preset safety accident does not occur in the above-mentioned safety protection module 3 or the above, and the user interface sub-module 11 in the central coordination module 1 transmits the preset safety accident to the user through the connected input/output device. In this or these security protection modules 3 above. In addition, in the embodiment of the "long-term mode", only when the detection interface sub-module 31 in a certain security protection module 3 detects other preset security incidents (that is, in addition to some or some of the security protection modules 3 are centrally coordinated) The state of the occurrence of module 1 and all independent communication modules 2 beyond any preset upper limit distance has changed from before, for example: some or some of the default safety incidents did not occur and now occur The detection interface sub-module 31 in the security protection module 3 signals the communication sub-module 32 in the security protection module 3 to be related to the occurrence of a certain security accident or not. Change, the communication sub-module 32 in the security protection module 3 transmits radio wave signals to the communication sub-modules 12 and I in the central coordination module 1 or the communication sub-module 21 in each of the independent communication modules 2, and informs the central coordination module 1 The communication sub-module 12 in the communication sub-module 12 and/or the communication sub-module 21 in each individual communication module 2 New default safety incidents occur in this security protection module 3. However, the method of adjusting the preset upper limit distance may, but need not be, a pre-transmission when the radio wave signal is intermittently transmitted by the communication sub-module 12 in the central coordination module 1 and the communication sub-module 21 in the independent communication module 2 The greater the intensity ^) is, the larger the preset upper limit distance is, and the other method for adjusting the preset upper limit distance may also, but need not be, adjusted by the communication submodule 32 in the security protection module 3 as described above. The smaller the preset lower limit intensity _m ', _m ' of the radio wave signal is, the larger the above-mentioned preset upper limit distance is. In the embodiment of the "long-term mode", other operations than the above-described non-"long-term mode" are not different from the above description. The communication sub-module 32 in the above-mentioned security protection module 3 transmits radio wave signals bidirectionally with the communication sub-modules 12 and I in the central coordination module 1 or the communication sub-module 21 in each of the independent communication modules 2, respectively, although the radio wave signals Yes, but not necessarily based on a wireless personal area network, but if the wireless personal area network based on the Z _lg Bee network transmission protocol is taken as an example, the maximum transmission distance is about 75 meters, which means that the above-mentioned preset upper limit distance is the largest. It may be 75 meters, of course, as described above, by adjusting the preset intensity when the radio wave signal is transmitted by the communication sub-module 32 in the security protection module 3 and/or adjusting the radio wave signal by the central coordination module 1 The preset strengths ^) ' and I when the communication sub-module 12 in the communication sub-module 12 and the independent communication module 2 are transmitted are transmitted or the communication in the communication sub-module 12 and the independent communication module 2 in the central coordination module 1 is adjusted. the sub-module receives the radio wave signal 21 of a predetermined lower limit or regulate the intensity I _m and above the security module in the communication module 32 3 Receiving the radio wave signal of a predetermined intensity lower limit _m ', above the upper limit of the preset distance can be adjusted to any distance of 75 meters or less. In other words, the device provided by the specific embodiment not only effectively ensures that the protected target is within any preset upper limit distance below 75 meters from the user, otherwise the device will inform the user about the relevant preset safety accident. Occurs, and as long as the distance between the protected target and the user is less than the preset upper limit distance, if the protected target has any one or more other preset security incidents, the device can also inform the user about the Item or the occurrence of such a default security incident. However, 75 meters is already a considerable distance. Protected targets are rarely removed more than 75 meters away from users due to daily activities, applications, etc., so the significance of such protection in practical applications is more than enough. In addition, taking the ZigBee network transmission protocol-based wireless personal area network as an example, the communication sub-module 12 in the central coordination module 1 is The communication sub-module 32 in the security protection module 3 can be based on the Z _lg Bee coordinator and the ZigBee end device respectively. In the current state of the art, the Z _lg Bee coordinator and the terminal device are generally The system is implemented in a single-chip (System-on-a-chi or SoC) system. The weight of these systems is only a few grams, but the size is only a few millimeters and a few millimeters. Even with the associated auxiliary circuits, the total weight is still in grams. The total size is still in millimeters. Moreover, the power consumption of these system single chips is extremely low, and generally small batteries can maintain their operation for one to two years, so the "portability" of this embodiment is taken for granted. In general, this embodiment can coexist between practical application meaning and "portability." In addition, the method and device provided by the specific embodiment can detect and inform the user about the occurrence of a plurality of preset security incidents, and the preset security incidents can actually be expanded and combined according to the needs. A number of examples of related default security incidents have been detailed, and other examples of default security incidents are analogous, so the protection provided by this embodiment is not only comprehensive, but also scalable. In addition, in any of the above embodiments, if the communication sub-module 32 in the above-mentioned security protection module 3 is respectively associated with the communication sub-modules 12 and I in the central coordination module 1 or the communication sub-module 21 in each of the above-mentioned independent communication modules 2 The bidirectionally transmitted radio wave signal is not based on a transmission mode having an authentication facility, and the device of the specific embodiment requires an additional authentication facility to protect the data so that the communication submodule 12 in the central coordination module 1 is When the radio wave signal transmitted by the communication sub-module 32 in the above-mentioned security protection module 3 is directly received or received indirectly through the communication sub-module 21 in the above-mentioned independent communication module 2, the source security protection module 3 can be identified, thereby preventing By means of the communication sub-module 32 in the security protection module 3 of the device, the protection provided by the specific embodiment is deliberately deliberately solved. For example, referring to FIG. 2, the implementation of the data protection authentication facility may be, but not necessarily, as follows: Real-time clock 14 and decryption are provided in the central coordination module 1. The sub-module 15, and a real-time clock 34 and an encryption sub-module 35 are provided in each of the security protection modules 3, as shown in FIG. The decryption sub-module 15 in the central coordination module 1 and the encryption sub-module 35 in each of the security protection modules 3 described above employ the same encryption/decryption algorithm. In addition, the decryption sub-module 15 in the central coordination module 1 and the encryption sub-module 35 in each security protection module 3 each store a key, for example, if a symmetric key is adopted The system, the keys stored in the decryption sub-module 15 in the central coordination module 1 and the encryption sub-module 35 in each security protection module 3 are each a identical undisclosed symmetric key; or if an asymmetric key system is adopted The key stored in the decryption sub-module 15 in the central coordination module 1 is a public key, and the key stored in the encryption sub-module 35 in each security protection module 3 is a corresponding private key, and vice versa. The key stored in the encryption sub-module 35 in each security protection module 3 must be unfair. Whenever the communication sub-module 32 in a certain security protection module 3 needs to transmit a radio wave signal to the communication sub-module 12 in the central coordination module 1, the original signal content of the signal (for example: inform about the absence of one or more pre- The security incident occurs when the security protection module 3 is combined with the real-time time obtained from the real-time clock 34 in the security protection module 3 (for example, in series), and then the combined signal content is sent to the security protection module 3. The encryption sub-module 35 is encrypted by the undisclosed key stored in the encryption sub-module 35 and returned to the communication sub-module 32 in the security protection module 3. The communication sub-module 32 in the security protection module 3 is then encrypted. The signal content is directly transmitted by radio waves to the communication sub-modules 12 and I in the central coordination module 1 or the encrypted signal content is first transmitted by radio waves to the communication sub-module 21 in each individual communication module 2 and then forwarded to the central coordination. The communication sub-module 12 in the module 1 and the communication sub-module 12 in the central coordination module 1 then send the encrypted signal content to the central coordination module 1 The decryption sub-module 15 decrypts the key stored in the decryption sub-module 15 and returns to the communication sub-module 12 in the central coordination module 1. A part of the decrypted signal content is from the security protection module 3 The real time time obtained in the real time clock 34, which will be compared with the real time time obtained from the real time clock 14 in the central coordination module 1 at the time, if the difference between the two is less than a reasonable preset upper time error, then the above The decrypted signal content will be regarded as valid, otherwise it will be regarded as invalid, that is, the central coordination module 1 has not received the signal. If it is valid, the other part of the decrypted signal content is related. The portion of the original signal content is sent to the user interface sub-module 11 in the central coordination module 1 as described above, as is the case when the device does not require an additional authentication facility. The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It is considered as the scope of protection of the present invention.
