DESCRIPTION OF RELATED ART
Remote and distant located sites may be difficult and/or expensive to reach for surveillance or engineering personnel which is to perform measurement work on different types of equipment used at such sites. These types of sites may range from weather stations to dams and the equipment may be measurement equipment, surveillance equipment and other types of equipment.
Instead of having personnel sent out to these remote sites, money and personnel resources may be saved, by arranging for the equipment to, by it self, send the information needed using a radio link. The on-site visits would then be limited to battery changes for the radio equipment and measurements could be performed much more frequently than otherwise since no personnel need to be sent to the site. It is however quite power consuming to have a radio link up and running listening for commands sent from the operator and batteries supporting the radio link need to be somewhat big or may otherwise need frequent charging. It would therefore be beneficial if battery power consumption could be minimized for such a radio link.
SUMMARY OF INVENTION
The object of the present invention is thus to provide an apparatus and a system which minimize the power consumption used by equipment, communicating via a radio link with a user of said equipment, located at a remote site and using batteries as power source
The problems described above, with how to achieve an apparatus and a system which minimize the power consumption for a radio communication link, is solved by providing a communication apparatus comprising a first communication device arranged for receiving and transmitting data to and from a data bank through a radio communication interface, a data storage area arranged for storing data to be communicated between said data bank and a first equipment. Said communication apparatus further comprising a low power circuit, having considerable lower power consumption than said first communication devices, and where said first low power circuit being arranged for, at regular time intervals, activate power feeding to said first communication device. Said first communication device being arranged for transmitting a first message to said data bank when said power feed is activated, and said data bank being arranged for sending first data to said first communication device upon reception of said first message.
An advantage with the present invention is that a low power radio link is provided which enables fewer changes of battery for a battery powered radio link. Another advantage with the present invention is that fewer on-site visits are required for remote sites having battery powered radio communication. Another advantage is that it is possible to set up measurement equipment on sites, requiring radio communication for performing the measurements, which were not previously economical feasibly due to the required battery changes.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
First equipment 101 is located at a remote and distant location. Said first equipment 101 is measurement equipment located at a dam for measuring the water height. It is of course obvious that the specific site and the specific quantity measured are not important for the inventive concept but merely serves the purpose of a specific example. A communication apparatus 102 handles the communication between the equipment 101 and a data bank 103. The communication apparatus 102 will be further described below. A user 104 sends instructions using a cellular phone 105, in the form of data messages to the data bank 103. The data messages are stored in a memory 106 in said data bank 103. It is of course possible for the user 104 to use other types of communication means for storing the instructions in the data bank 103, such as TCP/IP, computer with direct link etc. The instructions may contain information for controlling the equipment 101 or possibly the communication apparatus 102, such as when to perform a measurement, what type of measurement to perform, order to send measured values, how often to poll for instructions etc.
The communication apparatus will regularly, with an interval to be set by the operator, poll the data bank for instruction by sending a message indicating that the communication apparatus 102 is ready to receive instructions stored in the data bank 103. When the data bank receives such a message the data bank will send all the instructions stored in the memory 106 to the communication apparatus which will treat all individual message accordingly.
The communication apparatus may also send data stored to the data bank, such as measured values. It is also possible that instruction may be received for a time for which such measurements shall be performed or measured values shall be sent.
In figure 2 is one preferred embodiment of the communication apparatus 102 in figure 1 according to the invention shown. A communication device 201 is connected to a battery source 202. The communication device 201 is a rather complex device implementing a complete receiving/transmitting unit as well as a protocol interpreter and message/instruction interpreter. The communication device 201 is thus rather power consuming. In this preferred embodiment the communication device 201 will receive instructions from the data bank and store them in a memory 203. The memory may then be used by the equipment 101 for reading new instructions. The communication device 201 may also send data stored in the memory 203 to the data bank 103, such as measured values .
A low power circuit 204 implementing only a timer will on regular intervals activate a switch 205. As can be seen from figure 2 the communication device is not normally connected to power and will thus not wear on the battery 202. When the low power circuit 204 activate the switch 205 the communication device 201 will be activated and will the send a message to the data bank indicating that the communication device 201 is ready to receive new instructions. When all instructions has been sent from the data bank, as indicated by an ending message, and all data stored m the memory 203 has been sent, the communication device 201 raise a line 206. The low power circuit 204 will then open the switch 205 disconnecting the communication device from power again. Thus has a low power communication apparatus been achieved since the low power circuit 204 consumes considerable less power than the complex communication device 201 which is only activated during the polling phase.
In figure 3 is another preferred embodiment of a communication apparatus 101 m figure 1 according to the invention disclosed. A communication device 301 is connected to a battery source 302. The communication device 301 is a rather complex device implementing a complete receiving/transmitting unit as well as a protocol interpreter and message/instruction interpreter. The communication device 301 is thus rather power consuming. Low powers circuit 303, m principal only a timer, is connected to the battery 302, to a first switch 304 and to a second switch 305. The low power circuit 303 activates on a regular basis the communication device 301 as has been described m connection with figure 2. In a similar way may the low power circuit activate equipment 306 by closing the switch 305. Thus is both the communication device 301 and the equipment 306 individually controlled by the low power circuit 303. If messages are received from the data bank 103, which only comprises instructions to the communication device 301, the equipment can be kept off power. In instructions is received which require that the equipment shall be activated at times separate from the times for which communication is required this is also achievable .
The invention being thus described, it will be obvious that the same may be varied m many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
