Detailed Description

It should be noted that the embodiments and features of the embodiments can be combined with each other without conflict, and the present application will be further described in detail with reference to the drawings and specific embodiments.

As shown in fig. 1, a computer-implemented wireless security monitoring device, the system includes a method of tin foil monitoring the status or change of status of a container using one or more monitoring units mounted on the container. The monitoring unit preferably includes a power source, sensors using reflected energy with programmable parameters, sensor identification, recording capabilities on a time axis, long term memory, and the ability to rebroadcast information on radio frequency identification radio technologies. Programmable monitoring hardware in the monitoring unit detects significant changes in sensor output as a triggering event. The programmable monitoring hardware includes a memory for storing container identification information. The sensor may comprise a conventional device that can detect various forms of energy, including visible light, infrared light, magnetic fields, radio frequency energy, and sound. This event may be recorded as a subsequent readout and/or a radio frequency transmission may be generated immediately. In one embodiment, the monitoring unit is mounted in a container suitable for long distance transport. The sensor arrangement causes opening and closing of the container door to produce a change in the sensor output that is detected by the monitoring hardware as a triggering event. The triggering event may be used for security of tamper detection. The status and record information contained in the monitoring unit can be read by radio frequency communication with any suitably equipped device, including hand-held devices and laptops.

Fig. 1 depicts a system 20 according to the present invention. The system 20 includes one or more monitoring units 21 and one or more readers 30 for reading information from the monitoring units 21 or communicating with the monitoring units 21, such as handheld/mobile devices 31, laptop computers 32, desktop computers 33 and/or dedicated fixed location devices 34. Each reader 30 has radio frequency capability and may be a commercially available card that plugs into a slot of a computer. The card has a transmitter, a receiver and an antenna. The reader 30 preferably sends and receives radio signals to the monitoring group 21. The monitoring unit 21 includes one or more sensors 22 and a radio frequency transmitter/receiver 25. Radio frequency capability is limited to transmissions for certain applications. The monitoring unit 21 is built into the monitoring electronics 24, which includes a microcomputer, memory and interface hardware to the sensor 22. The program or firmware that controls the monitoring electronics 24 is developed using standard programming equipment and techniques. Each monitoring unit 21 includes the capability of an active RFID tag because it has memory to store identification information associated with the container to which it is attached. The rf transmitter/receiver 25 has an address or ID associated with it for identifying transmissions from it and from it, independent of the container's identification information. Any radio device capable of direct contact and recognizing from its signal as a unique single unit is a radio frequency identification radio may be used within the scope of the present invention. Such as a GSM handset. Ultra-wideband radio, satellite radio, and spread spectrum radio. Any of the radios described above may be substituted for the radio frequency transmitter/receiver 25. Since the number 21 monitoring unit is intended to move with the container, a self-sufficient power source, such as a battery, is required.

In certain applications, a large number of monitoring units 21 may be used simultaneously in a yard, warehouse, etc. Various containers may be equipped with a monitoring unit 21. The monitoring unit 21 may communicate via radio frequency transmission and respond individually or in groups. The distance between readers 30 and the actual rf transmitter/receiver function 25 of the monitoring unit 21 and various environmental factors such as physical characteristics of the container, but typically utilities and signals up to 300 feet in distance may be passed through a container. Active RFID technology is commercially available and the present invention may be implemented, in part, using active RFID technology. The sensor 22 is used to monitor changes in the environment in the container. For example, the opening and closing of the door may be detected. The sensors may also be used to detect movement of cargo or intrusion into the container. The sensor typically uses reflected energy, for example, the presence of a door can be sensed by transmitting and receiving the reflected energy. This method does not require breaking or cutting of wires or cables to sound an alarm, nor does it require switches or electromagnetic contacts to operate or sound an alarm. The present invention is not limited to any particular type of sensor. The sensors 22, which may be usefully included in the monitoring unit 21 according to the present invention, include conventional devices for detecting various forms of energy, including visible light, inertial light, magnetic fields, radio frequency energy, and sound.

Fig. 2 illustrates an embodiment of monitoring unit 21 using RFID tag 54. This embodiment can be used for tamper detection security. The sensor 22 is connected to a suitable analogue interface 42, which interface 42 is in turn connected to an analogue to digital converter 44. The analog interface 42 may also be connected directly to the digital logic bus 46 because some microcomputer devices have a built-in a/D converter. The microprocessor executes a control program stored in the memory. The microprocessor and memory may be part of a single integrated circuit such as a microcomputer. Power was supplied by battery No. 52, which was monitored by a power supply monitor No. 54. The avatar RF communication here is a software program that is connected by a separate RFID tag 54 to the microprocessor 48. the separate RFID tag contains the radio frequency circuitry, battery, antenna, logic circuitry and time records of non-volatile memory. This timeline may record events and recover as events occur. When the monitoring sensor detects a triggering event such as a door open, the fault signal is stored in volatile memory until it can be transferred to the self-contained RFID tag's timeline. The reader can then read this information.

The monitoring unit 21 of the present invention monitors the safety of any container, crate or container, immediately or subsequently disseminated by monitoring conditions such as door position or opening devices and recording such information. More specifically, the position of the door, etc. is returned to the sensor by transmitting and receiving energy, as it is reflected to the door. When the door is opened, the energy received by the sensor changes, and a fault state occurs. The fault signal is then immediately replayed and/or recorded with a relative or real time timestamp for transmission by the radio frequency communication signal.

The device may use sensors instead of physical seals or electromechanical switches to monitor the door, door jam, door frame, moving opening or moving side (hereinafter "door") depending on its installation location. The device allows the sensor to detect a fault condition when the door is moved and record it as a time stamp accessible to the RFID tag for transmission to the RFID reader.

The sensor 22 is preferably placed in close proximity to a door, cargo or other monitored object. The maximum distance is limited by the sensor capabilities. The monitoring unit 21 may be mounted inside the container with screws, magnets, etc. The sensor is preferably fitted with an energy transmitter and receiver aimed at the target, with no obstructions between the sensor and the target. When the target moves or is disturbed, the sensor detects the change or no change of the reflected energy of the target. A difference or absence of energy indicative of object motion is a fault or trigger event. The sensor 22 may be similar to a commercial SICK ELF sensor in SIC technology information documents.

The signal indicative of the fault is then detected by the microprocessor 48 or other logic circuit, which is stored in a memory separate from or internal to the microprocessor or microcomputer, as shown in FIG. 2. Since it is useful to know when a fault occurs and it is necessary to record the error, the information on the microprocessor's fault zone is memorized in its volatile memory until it can record the relative time in non-volatile memory or use the time stamp of a real time clock. Once in the non-volatile memory, information about the failure may be read by the RFID tag 54. Once the fault is recorded in non-volatile memory, the microprocessor clears the fault condition from memory and receives the next fault again.

The RFID tag 54 used in the above-described embodiment of the invention may be a commercially available identitec Solutions i-Q series of active uhf tags i-Q series described in the document. The RFID tags used in the present invention are active and must have the ability to access fault information, including the timestamp, or in the case of the Identec i-Q tag, the timestamp capability, which is actually part of the tag's memory capability. In the embodiment, the Identec tag directly obtains the fault information from the microprocessor through an external lead wire, and stores the fault on a time axis in the memory of the Identec tag. The advantage of the above method is that the time axis can be extended due to the zooming effect of using two devices with memory. An example of this is that the Identec i-Q tag has a battery life of 5 years and 32K memory and can record 13312 events or readings on a time axis, which means that a transit time of 30 days is covered, which can read the sensor every 20 seconds. In order to provide adequate protection on the door, the sensor must monitor continuously or at least every few seconds. One way to achieve this is to record the event as described above and save it in volatile memory for more than 20 seconds until it can be recorded on non-volatile memory, which is activated by the Identec tag every 20 seconds. The disadvantage of this method is that the recorded failure time is only within 20 seconds. In this embodiment, the sensor is always in the on position, just like the Identec tag. Because the sensor registers a fault when there is no energy reflected back to the sensor, a fault condition will always occur if the battery is disconnected, removed, or broken. Likewise, if no failure occurs, the correct function is displayed and successful installation is indicated. This information can be read and tested at installation time using a reader.

In an alternate embodiment of the monitoring unit 21 of the present invention, the RFID tag 54 need not have timeline storage capability. In this embodiment, when a triggering event occurs, the fault signal from the sensor 22 is stored on a timeline or real time clock in the memory 49 of the monitoring unit 21, where the radio frequency circuitry can be read by a reader. In this case, the microprocessor would be programmed to continuously monitor the sensors or turn them on at predetermined intervals to look for a fault condition. When a fault occurs, it can be replayed immediately or recorded directly on the time axis or real-time clock of the microprocessor logic circuit. The microprocessor will also provide memory and interfaces and logic for the RFID circuitry, and in this embodiment, the microprocessor can be directly accessed by the RFID circuitry to perform additional functions, such as turning the door sensor off and on. Reading values from the sensor to determine if it is functioning correctly, changing the gain or sensitivity on the sensor to adjust or calibrate the sensor due to differences in the sensor mounting distance from the door, or the reflection of its environment.

For the purposes of the present invention, the logic control, and monitoring sensors and the timetable or real time clock are part of the RFID circuitry, and its memory or memory maintained in a separate memory access a self contained RFID tag and memory for subsequent propagation as long as the fault information mediation is suitable for transmitting or storing the timestamp.

The fault is recorded on long term memory associated with the time stamp and where the RFID circuit is accessible it must be transmitted to a reader 30 for use. RFID tags may be read with a fixed or hand-held reader. The reader may also read the information on the tag as a rebroadcast device and then transmit the information via remote technology.

The alternative embodiment of the monitoring unit 21 shown in fig. 3 uses an RS485 serial interface 62 to transmit data from the microprocessor 48 to the radio transmitter/receiver 25, which transmitter/receiver 25 may be any alternative. As described above. In the present embodiment, the monitoring unit 21 is independent and independent of the function provided by the RFID tag. All functional control, logic and memory are contained within monitor unit number 21, whose firmware and radio are used for communication only.

The monitoring unit 21 contains memory for storing important information about the container, such as the owner's name, the contents or inventory of the container, and contact information about the particular cargo being monitored. In addition, the monitoring unit 21 contains data recorded from sensors, for example the status of the container doors (security alarm). Encryption of sensitive data is handled by the reader. Therefore, when data is written to monitoring unit number 21 or RFID tag 54 memory, the reader's application must encrypt the data. In this way, only authorized readers and users can see the data, and a few with proper authority can change the data. Any unauthorized attempt to modify the data will result in the electronic envelope being breached, and once the electronic seal is breached, a malfunction will occur and appropriate notification can be sent. Data may be written by a three step encryption process in which the data to be written is first encrypted using rsa standard encryption algorithms (64, 128 or 1024 bits depending on the country in which the application is used). An initial checksum key is stored in the data stream for verifying that the data structure is complete upon decryption. The resulting data is then preferably compressed using prior art compression methods to both optimize space in the tag memory and provide additional data scrambling.

When reading data from the 21 st monitoring unit, the reader will reverse execution. At the end of the decryption process, the checksum key will be tested for validity, indicating that the data has in fact returned to its original state. Some or all of the data is available to the user based on the user's authorization.

An embodiment of the method of the invention using the 21 st monitoring unit is as follows. The shipper holds the goods to be shipped in a container. The container door has closed and the shipper records the container as "closed" using a hand-held (or fixed) reader. The reader updates the number 21 monitoring unit with a data packet including, but not limited to, the date and time the container was registered as closed and the username that logged into the reader when the container was registered as the owner information for the closure. Inventory information, and documentation locations for related shipping information. This data is written to the monitoring unit 21 using the procedure described above. At this time, the 21 st monitoring unit starts to start. Automatically calibrate and begin monitoring sensor targets, doors, cargo, etc. The device will self-calibrate itself creating an average baseline value and then monitor for changes in this value, which will indicate a fault. All values or faults (values not within the set parameters) may optionally be recorded periodically in the memory of the RFID tag and in the real time clock. The fault will sound an alarm or the recorded record will be available for remote access using RFID technology. The monitoring process continues until the container is received by a waypoint during the transportation. When the monitoring unit 21 comes into contact with an authorized reader. The data is then read into the application software, the encryption process is reversed, and the application software tests the integrity of the data in each process. The user can then view the data. If the waypoint is the end of the transport, the user may choose to receive the container. Thus, the monitoring unit 21 is registered as "open".

The 21 st monitoring unit has a command set to which it responds, which may vary from application to application. Each 21 st monitoring unit has a unique address to which it responds, but preferably it also responds to selected broadcast commands directed to all monitoring units. The broadcast command may contain an unassigned address, such as "00," indicating that all units should receive the command. However, these units do not respond to the broadcast command, so a typical use of the broadcast command is to wake up all units in preparation for a subsequent individual command. The NOP command containing the address of the monitoring unit may also be used to wake up the unit. Another general command that should be executed at the monitoring strand is "sleep". In the sleep mode, energy is conserved. Since it is expected that there will be various types/embodiments of monitoring units, an identification number corresponding to the type of monitoring unit should be specified, which identification number should be accessible by a command (e.g., "get unit ID"). It may be desirable to monitor the response of the unit for a command to change the address (e.g., "set address"). The "Set Address" command helps to avoid Address conflicts. Reading of failure information, etc., is stored in the monitoring unit 21 by a "get response" command. The amount of data returned by the unit will vary from application to application.

In addition to security, the invention can also be used to monitor and track the movement of items in a supply chain. Refer to fig. 4. Monitoring unit number 21, equipped with appropriate sensors, can sense the presence of objects moving in the supply chain and broadcast this information through the various readers described herein. In the supply chain, proximity sensors have been used to monitor and trigger events. Up to now, these sensors have been fixed in fixed positions. With this invention, the proximity detector can be wireless and therefore mobile, limited only by radio range. The firmware programming for object tracking or counting in the monitoring unit 21 is different from that for the security application. A trigger event does not imply a fault condition but simply requires a sufficient length of time to be logged for transmission to the reader. One application of the present invention as shown in fig. 4 would be to detect an object 71. As they move from one location to another. 72 years or container. In this application it is important to record or log events on the mobile unit, especially in case of multiple mobile units, and thus the possibility of different mobile units regarding which mobile unit the object is placed. In such an application, each mobile unit would be equipped with one or more sensors 22 for opening the mobile unit or container. Each monitoring unit 21 will have a radio transmitter 25 which in this application is only capable of transmitting. When an object 74 is placed in the container, the proximity sensor 22 in the monitoring unit 21 will see the event by reflecting the signal and broadcast the event to the reader via the radio frequency transmitter, which will notice that the particular object is placed in the particular container. In this way, as individual objects move into individual receptacles, it is possible to track them, and thereby track and verify that they have moved into the correct receptacle 72 for placement by an operator, automated sorting equipment, or the like.

In a preferred embodiment, the monitoring of the sensors uses programmable parameters to determine when a triggering event occurs. Each sensor and application environment has a certain level of noise in its output or extraneous changes that can be considered normal. To avoid recording and transmitting extraneous information, programmable parameters can be used to filter the sensor output. As part of the manufacturing process, a set of default parameters is written into the non-volatile memory of the monitoring unit. The selected parameters of a particular sensor may be changed by commands sent and received to the 21 st monitoring unit. Examples of parameters are sensor sampling rate (frequency of readings taken by the monitoring unit 21), sensitivity or threshold parameters, output type (sensor output activated to "On" condition or sensor output activated to "of" condition), alarm signal duration (time the alarm is maintained until reset and ready for next notification), and boundary parameters such as maximum temperature, maximum impact, minimum radiation level, etc., all being default values at the factory.

It is preferred that the 21 st monitoring unit includes a sleep mode in which power is conserved. In the sleep mode, the microprocessor enters a sleep state to save power. An interrupt driven timer is set to periodically wake up the microprocessor to read data and perform other tasks. Temperature, humidity and other static sensors wake up at a predetermined sampling rate (see parameters above) and then make measurements. As temperature etc. can usually be recorded over time. The measurement itself is not necessarily a trigger event to record, so it sleeps to conserve power, and they wake up to record the current reading. The log of recorded values is readable when a command is received from the reader.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made herein without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
