Description

The invention relates to a safety system for controlling and/or monitoring at least one door lock for securing escape routes, comprising at least one release element, in particular an emergency button, and a door lock controller for controlling a locking mechanism, wherein the release element and the door lock controller are connected to each other via a first bus system. Safety systems with an emergency button for securing escape routes are known. When the emergency button is activated, a door lock is unlocked, allowing a user to escape in case of danger. EP 2 725 172 A2 It is known to connect an emergency button and a door lock via a bus system. It remains unclear whether and how non-safety-related functions can be integrated into a security system. Furthermore, the question arises as to how a connection between a central unit and the emergency button and door lock can be designed. The document EP 2 725 172 A2 discloses a safety system for door control having the features of the preamble of claim 1. The document DE 44 43 391 A1 This concerns a system of locks that can be controlled by a controller via a bus. The DE 10 2014 113647 A1 This concerns a solution for a security system for door control to secure escape routes with a remote central unit, which, however, only has one bus. The document EP 2 366 860 A2 Disclosing a safety system for door control with a control device for controlling redundant drive motors, which is equipped with two redundant computer units and is configured to process signals from an emergency switching device and a signaling device for detecting hazardous situations, in particular the occurrence of fire or smoke. The document EP 2 555 169 A2 discloses a safety system for door control with an escape route terminal that can process signals from a local emergency button, a remote access control device and a remote fire alarm system and can accordingly control the unlocking of the door lock. It is therefore an object of the present invention to provide a safety system that, in particular, meets a variety of tasks in a simple and/or safe manner. This problem is solved by a safety system according to independent claim 1. Advantageous embodiments of the safety system are specified in the dependent claims, the description, and the figures. The features mentioned in the description and in the claims can be essential to the invention individually or in combination. The previously derived and demonstrated task is solved, starting from the safety system described at the beginning, by the fact that the safety system includes a control device, wherein the control device is connected to the triggering element and/or to the door locking control via the first bus system. The safety system includes the first bus system. In the following, a connection to a bus system is understood to mean a direct connection, such that a component connected to the bus system is considered a bus participant of the bus system with its own bus address. The release element and the door locking control are connected to the first bus system. The control device is also connected to the first bus system. The control device preferably serves to perform at least one non-safety-related function. Because the control device is connected to the first bus system... If the control device is connected to a bus system, it can easily communicate with at least one other bus participant of the first bus system. The release element includes an actuating element. Actuation of the actuating element can trigger the locking mechanism for unlocking. The release element is preferably designed as an emergency button. In this case, the actuating element of the release element corresponds to the actuating element of the emergency button. Alternatively, the release element can be designed as a panic bar assembly. In this case, the actuating element is designed as a panic bar. The release element can also be designed as a hardware assembly. In this case, the actuating element is, for example, designed as a door handle. Locking refers to the process of moving the door lock or locking mechanism into a locked state. Unlocking refers to the process of moving the door lock or locking mechanism into an unlocked state. The security system may include the locking mechanism. The locking mechanism can be, for example, electromechanical or purely electromagnetic. The locking mechanism includes, for example, at least one coil. Control of the locking mechanism for locking or unlocking can be implemented, in particular, by switching an electrical power supply on or off. The electrical power supply can serve to supply the coil with electrical current. An electromagnetic locking mechanism is exemplified in the DE100 50 111 C1 As described. In the unlocked state, for example, no magnetic forces act on the door. In the locked state, for example, magnetic forces act on a door. An electromechanical locking mechanism has a mechanical connection to the door when locked
