Description

A kind of wireless supervisory control system for commodity anti-theft

Technical field

The present invention relates to commodity anti-theft field more particularly to a kind of wireless supervisory control systems for commodity anti-theft.

Background technique

With the development of commodity experience type service, the displaying of commodity and experience functions are more to buyer or potential purchase Buyer is open, and at the same time, the requirement to commodity anti-theft can also be continuously improved.How on the one hand each of experiencer is met as far as possible Kind of demand, and as far as possible to experiencer show commodity institute is functional and most good easily one side, on the other hand mention again The anti-person's of harhoring evil intentions pilferage behavior that may be present, be reduced as far as in addition prevent commodity show and experience of the process in exist , the hidden danger that may be stolen.For the commodity with experience functions, it can leave and put originally because of being experienced at any time Position, the variation of this position do not represent commodity and are bound to the presence of stolen risk, but do not represent yet commodity be centainly not present it is stolen Risk, it is therefore desirable to certain measure is set, and to judge as precisely as possible, commodity whether there is stolen risk.

In existing most of displaying commodity anti-theft fields, it will usually be equipped with a commodity-exhibiting device for each commodity (and being properly termed as safety device), commodity are connected or are integrated on safety device, and safety device can be integral type, can also Be it is split type, commodity can be connected by cable with safety device, when the combination of safety device and commodity is destroyed, or Cable disconnects either some link of commodity and safety device entirely connected and is destroyed, and can think that commodity may be located In unsafe state, need to trigger burglar alarm, the people for prompting staff or warning that abnormal case is caused to occur, at this In the case of kind, safety device is it can be appreciated that having the function of sensor or containing sensor, sensor here can To be that physical sensors (contact induction) are also possible to electric transducer (electric current induction), sensor can be used for alarming, this The releasing of alarm needs the people for obtaining authorization or device to operate, therefore once triggering alarm, may will affect showground institute Interior whole order even influences the people for showing each experience in place, it is therefore desirable to reduce false alarm to the greatest extent, meanwhile, at present It is important that relatively focus in industry other than safety there are also be exactly experiencer experience sense by because experience sense by A possibility that whether pleasure directly influences overall merit and purchase of the experiencer to the various aspects of commodity, therefore promote experience The Experience Degree of person is extremely important for businessman to showing.

Currently in order to promoting experience effect, safety device (including bracing wire and attachment area) is reduced to the greatest extent to the shadow of experience It rings, has many corrective measures in the design to safety device itself, such as minimize under the premise of guaranteeing safety Contact of the safety device with commodity, or the retractility of enhancing cable, but safety device can not leave cable operation always.

In order to which solve the problems, such as cable involves bring experience effect, while also with the development of wireless technology, opening up Show commodity field, also have and propose the concept of wireless anti-theft, there are two types of current wireless anti-thefts, and one is using wireless side Formula is unlocked, there are also one is to safety device using wirelessly incuding, it will usually limited for safety device Certain region, this region are preset by hardware, once setting, unless changing hardware, otherwise can not be changed, and And hardware is needed to cooperate, for example, thief-proof (robber) the system EAS(Electronic Article of electronic goods Surveillance), it is one of commercial articles safety measure that current larger retail industry is widely used, EAS system is mainly by detecting Device (Sensor), decoder (Deactivator) and electronic tag (Electronic Label and Tag) three parts composition, Electronic tag is attached on commodity, detector is arranged in entrance, for detecting whether electronic tag leaves entrance, due to electricity The attachment of subtab and commodity needs to be unlocked by dedicated decoder, and the unlocking manner common people of decoder are in retail field It is unable to complete in institute, then cooperates the surveillance and control measure in retail location's arrangement, usually can meet antitheft requirement, but electronic tag Magnetic field may will affect the normal use of electronic product, therefore be not suitable for the displaying of electronic product, and even if this mould Formula can be used, but show place (the electronic product display Room, such as certain brand electronic product experience shop or communication Trade Fair Show experience the Room) and the difference of retail location (such as supermarket) be, as long as retail location's commodity can be recognized in retail location To be safety, but show that place might have different exhibition booths, for example, communication quotient's arrangement the experience Room may include it is multiple Brand, the exhibition booth between brand is independent from each other at this time, if some commodity has left the exhibition booth belonging to it actually also It is in non-controlling region, belongs to non-secure states, but for the experience Room as a whole, it is impossible to it is each exhibition booth Entrance is set, this has resulted in the unworthiness in some places.Moreover, this shape for setting safety zone by hardware Formula, once hardware failure or power-off, may cause the failure of system, alternatively, in terms of other, in point-to-point communication party In formula, it is more likely that will receive external interference, such as certain portable non-displaying that can send and receive signals just of experiencer Device in place, it is possible to cause wrong report (wrong report when similar to supermarket out).

On the other hand, a kind of equipment more commonly used in existing burglary protection system for commodities is monitoring device, and monitoring device can To be used to receive safety signal to judge whether commodity are in safe state, such monitoring device is usually all direct By the on-off of cable reception safety signal, such as cable, this can be used as a kind of safety signal of electricity, or pass through contact Receive sensor on safety signal, such as commodity or commodity with non-contacting mode and monitoring device occur it is physical It is detached from, can also be used as a kind of safety signal for monitoring device, sometimes, monitoring device can carry alarm module, when It receives safety signal directly to alarm by the alarm module of itself later, monitoring device can be called alarm dress again at this time Set, sometimes, monitoring device can again by cable connect warning device, after receiving safety signal, monitoring device just to Warning device issues alarm command/signal, and warning device is made to issue alarm signal.

In most of burglary protection system for commodities in the prior art, can by tripper come to monitoring device or Warning device is unlocked, and the function that monitoring device itself can be performed is to receive safety signal, and be parsed into alarm Instruction is sent to alarm module, and perhaps warning device monitoring device itself can not issue or assist to issue safety signal, In other words, whether commodity are in safe state this are one and are detached from the established rule of monitoring device that monitoring device is only used To execute this rule, it is also necessary to which other equipment, such as controller or external equipment come to some antitheft of burglary-resisting system Rule is preset.Moreover, most of monitoring devices in the prior art all need cable to connect, in particular for electronics The antitheft field of the displaying of product, as previously described, widely used electronic tag may not be suitable for showing in retail (supermarket) Commodity anti-theft, but in fact, monitoring device as in burglary protection system for commodities closest to one of equipment of commodity, can be in system In play bigger effect, if it is possible to the characteristic of monitoring device is adequately utilized, can simplify the structure of burglary-resisting system At promoting the performance of burglary-resisting system.

In addition, in burglary protection system for commodities, another more important equipment is sensor, on ordinary meaning, sensor It is the equipment for being used for inductive signal, in commodity anti-theft field, sensor is mainly used for incuding whether commodity are in safety The safety signal of state, this safety signal are usually to derive from, and whether commodity and cable keep being electrically connected or commodity and prison Whether control device is in contact condition, for example, the cable that sensor can be as commodity power supply, when the cable is cut off, sensing Electric current in device is just cut off, and electric current, which is cut off, at this time can serve as a safety signal, is sent to its connection by cable Monitoring device, monitoring device, which receives, will issue alarm command or alarm signal after this safety signal, if it is connecing Touch sensor, sometimes connector can also be used as a sensor, detect whether to keep connection or contact with commodity Sensor can be attached on commodity, using and commodity be detached from as a possible safety signal.

In traditional sense, sensor be for inductive signal and issue signal equipment, itself can't preset or Participate in the default rule for issuing signal, and for burglary protection system for commodities, sensor be suitable only for physical contact induction and Electric current incudes both modes, largely affects simplifying for burglary protection system for commodities, and traditional sensor changes The transmission of safety signal and mode is not generated, largely limits the applicability extension of burglary protection system for commodities.

Commodity anti-theft

Signified commodity anti-theft in the present invention, including commodity anti-theft and equipment related with commodity anti-theft, environment and some shapes State, for equipment for example for the safety equipment of commodity anti-theft, monitoring device, warning device, sensing apparatus etc., environment typically refers to quotient Application places or application environment locating for the antitheft system of product or the system of commodity anti-theft, some states may include commodity State, such as safe, non-security, normal, abnormal, the stable or unstable state that commodity are in can also be with Some states including burglary protection system for commodities.

Signified commodity anti-theft in the present invention, can also include some other contents related with commodity anti-theft, and commodity are anti- Robber is a biggish scope, is related to retail trade related with commodity, sales exhibition industry, shows industry, etc. institute in the present invention The commodity anti-theft of finger, especially for perhaps sales exhibition industry is showing or exhibiting and selling in industry have one in the related displaying of commodity Maximum feature is exactly that the buyer or potential buyer (personnel other than non-businessman) in place can carry out commodity It directly uses or experiences, this commodity anti-theft can usually have to turn to again shows commodity anti-theft industry, belongs to commodity anti-theft In one subdivision.

Usually, it shows that commodity anti-theft can be used in need to carry out functional display to buyer or potential buyer Some commodity, such as electronic product, certain functions of these commodity need user can be allowed to carry out in a situation of use where Understand, these commodity usually have the interface of certain man-machine interactives, and the person of being demonstrated can contact in a certain range and can show Plasticity or illustrative using these commodity all or part of function, so that the performance to commodity understands, in industry It is interior, sometimes also this commodity with functional display demand can be called the commodity with demand for experience, that is, not be demonstrated person The commodity being shown can be operated and be experienced in the condition and range of restriction, therefore, these commodity are can be by body What the person of testing directly contacted, experiencer can be in the range of sellers or commodity owner limit, such as in merchandising location Carry out using, but these commodity cannot be taken away experience place, due to show commodity ownership, still belong to sellers Or commodity holder, therefore, it is necessary to carry out anti-theft measure to it, these anti-theft measures do not limit the use of experiencer, And only limiting experiencer is taken away this place, or even in some cases, these anti-theft measures also need to consider as far as possible The use of experiencer is not interfered, better uses experience to enable them to obtain, this has any different in sale at whole-sale price Article it is carry-on antitheft, the article anti-theft in sale at whole-sale price usually only needs that article is prevented to be brought away from some place, and Article in sale (such as supermarket) at whole-sale price should not be experienced by the user, and experience is represented and used, such as in supermarket Food, therefore be usually to limit a region, it prevents user from taking away, while cooperating monitoring, prevents user in the area of restriction Direct commodity in use in domain.

The state of burglary protection system for commodities may include the working condition and off working state of burglary protection system for commodities, for work Make for state, if burglary protection system for commodities, can normally be worked in the state of expection, such as Normal Alarm, just Often instruction etc., it is believed that system is in normal working condition, on the contrary, it is believed that be in improper working condition, In In the present invention, improper working condition, and the device that can be monitored incude or monitor, and are carried out instead by alarming device Feedback, because, if in burglary protection system for commodities, some equipment is in improper working condition, it would be possible that influencing whether quotient Therefore the antitheft normal function of product is actually that can not protect if not having effective guarantee to the state of system itself Card, the anti-theft performance of system.It can also include the off working state of burglary protection system for commodities in some preferred modes, because It may also can be related to the safety of some performances, such as system itself of burglary protection system for commodities for off working state, in other words System it is private or exclusive, if system do not have it is good exclusive, guarantee only have system in equipment can be mutual Communication, then system is not inherently safe, it is possible to which some peripheral hardware can also realize the equipment in system and control, just It is that so-called system is easy to be hacked, does not also can guarantee safety in this case, therefore, inside burglary protection system for commodities State, it is also desirable to effectively be set.

In terms of commercial articles safety, it is believed that commodity can be in the two states of safe and/or non-security state, safety State and non-security state be in contrast, mainly can be used in commodity anti-theft in terms of, the concept of commodity anti-theft be in order to Commodity are made to be in the state of safety, once there is a situation where commodity are in non-security or are likely to be at non-security state, then It needs to sound an alarm, prompt sale or shows the staff in place.Alleged safe or non-security state, refers in the present invention It shows commodity state in which, refers in particular to show the relationship of commodity and anti-theft device in the case where being provided with anti-theft device State, in general, commodity are in us and think the state that will not be stolen, referred to as safe condition, it is believed that possible quilt The state of robber, referred to as non-secure states, whether anti-theft measure intact, show commodity whether be in anti-theft measure protection it Under, if it is then it is considered that be safe state, if it is not, so it is considered that whether An Quan state, that is, It says, this safe or non-security state can be for anti-theft measure, for example, anti-theft measure is will to show Commodity keep connecting with charging interface always, then, sensor just detects whether charging interface connect with commodity always, if Be, then it is in a safe condition, if disconnected, it is in non-secure states；Alternatively, if anti-theft measure is to make commodity always Charged state is kept, then, whether the charge cable that sensor just detects commodity keeps power transmission, if it is, in peace Total state, if it is not, then being in non-secure states；Or if anti-theft measure is, commodity are in clamped device clamping Firmly, then sensor just detects, whether commodity are in grasping part or whether commodity are kept in contact or pacify with clamping device Dress, if it is, it is in a safe condition, if it is not, then being in non-secure states；Etc..

Alarm signal

In commodity anti-theft field, alarm signal may include usually said safety signal, so-called safety signal just refer to by What sensor issued, for judging commodity signal whether in a safe condition,

In the present invention, alarm signal includes the alarm signal for warning abnormality and the police for warning unstable state Show signal, so-called abnormality is primarily referred to as the situation of commodity and unit exception etc., and so-called unstable state is main Refer to the state of the damaged condition of wire rod and the service life of monitoring device etc..

Two distinct types of alarm signal, producing method may be different, for example, for warning abnormality Alarm signal generation may is that monitoring device can preset in advance state threshold, preset state and predetermined warning it is enabled, and Threshold value, state and the warning of preset in advance enable to adjust by peripheral equipment.Sensor circuit is handled by sampling analysis To a real-time sampling value, which is compared with preset state threshold value, a new induction will be generated accordingly Circuit state；With the new state compared with default normal condition, it is judged whether or not abnormality generates.If generating one Then a new abnormality just goes to judge whether the state is predetermined warning and enables, if be predetermined, warning is enabled, and monitoring is set It is standby to convert abnormality to the alarm signal for being used to warn abnormality, then issue alarm signal；If not It is enabled to be predetermined warning, monitoring device does not issue alarm signal then.For warning the generation of the alarm signal of unstable state can To be: monitoring device meeting preset in advance stability threshold and predetermined warning are enabled, and the threshold value of preset in advance and warning are enabled It can be adjusted by peripheral equipment.Sensor circuit monitors that sampled value deviates pre-determined stability threshold value by sampling analysis, A unstable state can be generated.It is enabled that detection device judges whether the state is predetermined warning, enables if being predetermined warning, Monitoring device will convert the unstable state to the alarm signal for being used to warn unstable state, then issue warning Signal；If the state is not predetermined warning, detection device if, does not issue alarm signal.

Alarm signal can directly be issued by the warning circuit of monitoring device itself, monitoring device issue alarm signal with Afterwards, can first judge whether warning circuit itself is idle.If warning circuit is idle, monitoring device will be according to the kind of alarm signal Class is simultaneously converted alarm signal for the identifiable alarm signal of people by warning circuit；If warning circuit is busy, monitoring device The alarm signal newly issued will be added to alarm signal queue, handled later.Alternatively, alarm signal can also be by external Peripheral equipment issue alarm signal indirectly；Monitoring device can be sent the alarm signal of generation by wired or wireless mode To external output devices, after external output devices receive alarm signal, alarm signal is converted to the police that can be identified for people Show signal.

For the alarm signal for warning abnormality, when monitoring device receives the finger for stopping sending alarm signal It enables, then stops sending alarm signal；It then proceedes to sampling to determine, determines then to stop sending warning the result is that being not in abnormality Signal determines that result then continues to send alarm signal if it is abnormality is in；Alternatively, monitoring device preset state is modified Become original preset state to change, be then compared according to the state that sampling obtains with modified state, determines sampling Obtained state normally then stops sending alarm signal, otherwise continues to send.For for warning the warning of unstable state For signal, when sensor circuit sampled value is restored to range of normal value；Or monitoring device pre-determined stability threshold value is modified, and is made Sampled value is in range of normal value again；Or monitoring device receives stopping and sends instruction, can stop sending the unstable shape of warning The alarm signal of state.If sensor circuit sampled value deviation distance can send alarm signal after reaching a new range again； If sending alarm signal alternatively, the sampled value that sensor circuit samples deviates except pre-determined stability threshold limit range, Monitoring device receives stopping and sends instruction at this time, and monitoring device then stops sending and will not sending again, if sensor circuit Sampled value be restored to normal range (NR), then the interface can be determined again.

By the difference for the sense organ for acting on people, alarm signal be divided into visual alarm signal (such as comprising light, figure As etc.), sense of hearing alarm signal (such as including sound), tactile alerts signal (such as include vibration) etc..In some preferred sides In formula, visual alarm signal can distinguish level of signal with color, and red indicates that warning, orange expression are warned, and yellow expression mentions Show, green or white indicate normal condition.In some preferred modes, sense of hearing warning can be different with frequency, tone color, intensity Sound be distinguish.In some preferred modes, for enhance caution signal reliability, can using depending on, listen dual shape Formula.In some preferred modes, by the pressing degree of warning, alarm signal can be divided into alarm (Alarm), warning (warning), (prompt), message (message) etc. are prompted, in some preferred modes, above-mentioned alarm signal it is urgent Degree is successively successively decreased.
