Datalogger in hospital or care bed
A communication system for exchanging data between an actuator system and an external device, e.g. an operation where the communication system under the form of a gateway and a transcoder interprets the information in a bidirectional stream of data and distributes the information to both ends. The communication system is furthermore provided with a logger function, where the signals that are sent out to both sides of the gateway, are stored in a memory, so that the actions and signals that lead to an alteration on the actuator can later be reconstructed.
1. An electric actuator system comprising:
a linear actuator,
a controller,
a power supply,
an interface with connection means for receiving a signal or transmitting a signal, wherein the electric actuator system comprises means for registering and storing the information which is exchanged via the interface of the electric actuator system with connection means wherein said means for registering and storing the information is further configured to (i) provide the information with a timestamp indicating a time of occurrence relating to the information and (ii) store the timestamp with the stored information, wherein the stored information further includes an identification of transmitters and receivers in the form of a unique identifier, wherein the electric actuator system comprises a communication interface for communication between the controller and connected devices that are equipped to transmit or receive a signal from the controller, wherein one of said connected devices comprises an operating device for operating the electric actuator system, and wherein said means for registering and storing the information is further configured to store information comprising at least an input signal from the operating device configured to trigger an action from the controller.
2. The electric actuator system according to claim 1 , wherein the communication interface communicates between the devices by use of and including means for converting the stream of signals or bi-directional data that is communicated between the controller and the connected devices that are equipped to transmit or receive a signal from the controller, according to a clearly defined pattern in a protocol.
3. The electric actuator system according to claim 1 , wherein the connected devices that are equipped to transmit or receive a signal from the electric actuator system, can be further include one of or more of the following:
a sensor for receiving a signal,
a monitoring device for monitoring the electric actuator system,
a monitor showing the setting of the electric actuator system,
a contact for activating a connected device,
a sound emitter,
a light source,
a network connection,
a device for data processing, such as a computer.
4. The electric actuator system according to claim 1 , wherein the interface electric actuator system with connection means is either wired or wireless.
5. The electric actuator system according to claim 1 , wherein the means for registering and storing the information that is exchanged with the electric actuator system is further configured to register and store the communication that is transmitted between the communication interface and the controller and/or the communication that is transmitted between the communication interface and the devices that are equipped to transmit a signal to or receive a signal from the electric actuator system.
6. The electric actuator system according to claim 5 , wherein the means for registering and storing the communication is designed as a part of the controller and/or as a part of the communication interface.
7. The electric actuator system according to claim 5 , wherein the means to register and store the communication stores the information in a memory that is designed in connection to the controller, the communication interface or a separate memory device such as, for example, a memory printed circuit board.
8. The electric actuator system according to claim 7 , wherein the means to register and store is further configured to store information stored for each event selected from the group comprising:
the identification of transmitters and receivers (a controller, a communication interface or a connected device) in the form of a unique identifier such as a MAC with an associated SW number and a SW embodiment,
ping signals and (handshake) confirmation (is the system alive?)
voltage level on the electric actuator system and the interface,
clock and data signals,
control data or information data in the data package,
changes in the configuration of connections on the communication interface (ID and mapping)
communication failure/error between communication interface and controller regarding a connected device.
9. A hospital bed or care bed comprising the electric actuator system according to claim 1 .
