Abstract

An electronically codable lock system is described.

This comprises a housing with a locking element that can be locked and unlocked, in particular a curtain bracket that can be locked and unlocked by a locking mechanism. The locking mechanism can be unlocked by means of an electronic code evaluator via a control line when evaluating a valid code. A code receiver is assigned to the code evaluator and receives data from an external authorization card with a code transmitter via an electromagnetic, optical, acoustic or galvanic transmission path.

Description

The invention relates to an electronically codable lock system according to the preamble of claim 1.

Network operator for energy supply, water and wastewater supply and telecommunications maintain a large number of business premises spread over the supply area are and often operated without the constant presence of personnel become. The operating stations are against unauthorized persons Access secured. In addition to fencing with closable Gates are often other lockable entrances, doors and windows in buildings.

Until now, maintenance and operating personnel had needed one Variety of keys to gain access to permanent establishments receive. They differ for security reasons Locks, so that the authorized operating personnel Variety of keys must be carried if different Business premises are visited.

The invention has for its object a lock system for such operating sites, which is and operating personnel each with a single credential is open and allows the permissions to be individually assigned, changed or deleted.

This task is done with an electronically coded lock system according to the preamble of claim 1 by the in characteristic part specified features solved.

Further developments and advantageous refinements result from the subclaims.

In the lock system according to the invention, a code is a Authorization card carried by maintenance and operating personnel transmitted to the lock system via a code transmitter and evaluated by means of a code evaluator, which at Validity unlocked a latch mechanism. In addition to a supplementary code can also be used for a basic code, the system number, location, customer number, customer group and hierarchy level.

The code is sent to the code evaluator via a first wireless Transmitted as electromagnetic or interface optical interface can be formed. By a The second code reader can be a wireless interface Connection to an external access control system or external database and the validity of the authorization card have it checked. After verification there will be a validity response retransfer that with valid credentials unlocked the locking mechanism or if it is invalid ID card locked the latch mechanism leaves.

An external database can be created via a public or in-house Telecommunication network can be reached and is much easier and faster to maintain. Then she is for a practically unlimited number of clients, ie in in this case available from electronic lock systems. In addition, the storage space of the database is currently being used a large number of different authorization codes Role as if different authorization codes in each individual lock system would have to be filed and locally required storage space for this.

Alternatively, authorization data can also be used in the code evaluator be saved over the second wireless interface be updated. In this case, one is found Checking access authorization internally by the electronic Code evaluator of the lock system instead. This can either generally take place or in the event of a faulty connection to the external access control system or the external database as a temporary emergency operation to ensure the Functionality of the lock system.

The advantage of the second wireless interface is that that the lock system without galvanic connection to external access control system or to the external database can work independently, e.g. B. outdoors as a padlock or as a built-in lock on buildings without their own Data lines or power lines. Still is given a high level of security against manipulation, and there is furthermore the possibility of reallocations, changes or deletions of permissions without mechanical Intervene or replace the lock system.

This considerably simplifies administration of accesses and credentials and for that Maintenance and operating personnel have the advantage of being able to work with one single credential access to different Lock systems can get.

The first interface is preferably a transponder interface for the frequency range between 100 kHz and 15 MHz.

This frequency range also enables data transmission then if there is no direct view between the encoder and the lock-side receiver of the first wireless interface consists. So there is the possibility of the lock system without affecting the first wireless interface Protect the weather or vandalism.

In the case of further training, the transponder interface transmits inductive or electromagnetic energy for feeding a Transponders in the credentials, and between the Transponder of the ID card and the code interpreter data is transferred to check the authorization.

With this solution, small, handy passive transponders can be used are used, what for the maintenance and operating personnel means ease of use. In addition, use common components for access control systems, especially ID cards with a code transmitter, which are already for access to other buildings with connection to the electrical Supply network can be used.

Alternatively, the first interface can be used as an interface for a cellular network should be formed.

In this case it is possible instead of an additional credential to use a mobile phone as a code transmitter. This is usually the case for maintenance and operating personnel carried mobile phone in addition to its actual Determination as a communication device also as a code transmitter can be used with a credential so that then an additional credential is not necessary.

The code can correspond to the SIM card number or separately from a memory or via the keyboard, if necessary in connection with the SIM card number become.

According to a further development, the first interface can additionally a near field sensor for detecting the emission of a include cell phones serving as code transmitters.

This execution ensures that the code is over the cell phone can only be entered effectively, if the employee is in the immediate vicinity of the Schloss-Systems stops and therefore only the one immediately adjacent Lock system is unlocked, but not at the same time all lock systems programmed with the same code.

Alternatively, it can be provided that the first interface additionally a display to show a constantly changing Codes is assigned, which is via the keyboard as the code transmitter serving mobile phones from maintenance and operating personnel is to be entered.

This measure also ensures that only that is nearby located lock system can be unlocked, whose Display is visible because of the constantly changing code individual lock systems are individualized.

The second interface preferably comprises a receiver or a transceiver for a radio link of low power in an approved frequency range, especially 433 MHz or 868 MHz, or for a cellular network.

This makes it possible to use a data communication short distance to a stationary interface transmitter to manufacture or transceiver, which in turn is then via data lines with the external access control system or the external database is connected. Radio links are possible here small power distances of several tens of meters or a few hundred for a cellular network Meters to kilometers to the next head-end station.

Due to the radio link of low power, several neighboring ones can be used Lock systems with each other and / or with a relay station communicate. One of the lock systems or the The relay station then takes over the connection to an external one Access control system or database. For this is then only one common interface required. Because in practical Operation only one lock system is active at a time no risk of data collision due to simultaneous Transmission request for multiple lock systems.

The code evaluator can store different data Credential codes include that over the second wireless interface are upgradeable. During training the second interface as unidirectional between the external access control system or the external database and the code evaluator of the locking mechanism Access check by the code evaluator generally with the local stored code. When the second interface is formed as bidirectional between the external access control system or the external database and the code evaluator of the locking mechanism the access check is carried out by the code interpreter only if this interface fails with the locally saved one Code.

As a result, access is always possible with different Authorization cards through different Maintenance and operating personnel enabled, with a remote controlled Management of permissions is possible and also an emergency operation during the failure of the second interface can be maintained.

Furthermore, the code evaluator can also include a timer, which as a real-time clock, possibly with the time of day and additionally Date or is designed as a counter. additionally can be an entrance exam with a general or temporary Authorization of the credential can be linked.

It is then possible to access a date, a time or make it dependent on a meter reading. This can a credential with unchanged code is still time-selective be used. A temporary authorization can also include duration or frequency of access. You can internally or assigned externally and also after one or more times Usage changed or deleted.

The housing of the lock system can consist of two parts, a first part of which is made of metal and the Locking mechanism includes and a second part made of plastic exists and an antenna of the code receiver or transmitter as well where applicable, the transceiver or transceivers for a radio link of low power and / or a cellular network include. The remaining components can be completely or partially arranged in the first or second part of the housing his.

This structure makes it particularly security-relevant To accommodate parts in the metal housing and thus against sabotage to protect. In contrast, the antenna, which is used to achieve good radiation properties but protected must be attached, in the housing part made of plastic to be ordered. Other less security-relevant ones can also be found there Parts, for example batteries, arranged to simplify their exchange.

When arranging electrical components in both parts of the housing, these can be connected to one another by contacts his.

In principle, it is therefore largely optional in which one of the two parts the electrical and electronic components are housed, unless this is due to safety-related Requirements is specified.

To increase the security of data communication between Separable parts of the housing can also use internal encryption devices with authentication in both parts of the housing can be provided.

These only provide the function of the two parts of the housing forth if parts that belong together are used. An improper exchange of different parts of the Housing z. B. different lock systems is recognized and prevents a function. Only with suitable parts the housing is automatically restored after assembly Operational readiness established.

It is also provided that when training as a padlock a position transmitter for the bolt or padlock is connected to the code interpreter.

In this way it can be recognized whether the bolt or curtain returned to the correct position after closing and also whether the lock is opened by force.

The invention is described below using an exemplary embodiment described, which is shown in the drawing.
