Definitions

  • the present invention relates to a method of control of an ionizing ray generator.
  • the present invention also relates to the installation intended for the implementation of this process.
  • X-ray, alpha or gamma generators or other ionizing radiation requires a desk control which must be placed at a sufficient distance source of radiation to avoid danger excessive operator radiation.
  • control desk is connected to the generator by a cable of sufficient length to allow the operator to find enough distant, and often the length of the cable is used as a reference to the operator or installer to know the safety distance where the operator should be placed.
  • this cable can be a handicap major for the operator and / or for other persons may be within the safety distance of the generator.
  • the present invention aims to provide a method of controlling an ionizing ray generator which provides very high security, avoids inconvenience mentioned above and brings other advantages which will be described below.
  • a purpose complementary to this invention is to provide an installation intended for implementation of this process, bringing numerous safety and site management benefits.
  • the present invention relates to a method for controlling a ray generator ionizers in which, conventionally, a relationship between the generator and the control device.
  • the method consists in to use the hertzian way to establish such relationship. It follows that the operator has the possibility of place its control console so as to have a general view of the generator surroundings to intervene in case other people enter the area insecurity around the generator.
  • the relationship between the generator and the control device includes the transmission of a generator-specific code and a code suitable for its connection with the control device and the communication of these two codes to the generator during each link between the generator and the ordered.
  • the code specific to the connection of the command is modified with each relation of the generator with another control device.
  • the code specific to the connection with the control device, for each relationship with a other control device is modified according to the same mathematical rule.
  • modification of the code specific to the connection with the control device consists of incrementation by addition of a specified number. This use of a incremental number is the simplest mode, but generally sufficient to effect said modification and make possible the possible determination of the number of changes made.
  • the clean code at the connection with the controller includes no only a variable part, but also a fixed part specific to the control device.
  • a fixed part specific to the control device for example, taking as a fixed part all or part determined from the production number of the order, it is you can simply prevent a generator from finding a reasonable distance from another generator wrongly receives instructions from the command assigned to this other generator, which would happen especially if the two orders at the same time had the same number incremental and if the other command still had in memory the code of the first generator that she had managed previously.
  • any relationship between the generator and the control device is established over the air.
  • the means of radio transmission being present, one avoids thus the need and possible disadvantages of a other mode of transmission, for example by cable.
  • the generator communicates initially the two codes to the controller when of a pairing that is carried out at the time of the constitution of a new generator-control device pair.
  • initial codes we reinforce security by avoiding errors that could occur during transmission manual codes.
  • control device near the local device generator control.
  • local device of generator control means the part of the generator, sometimes called a suitcase, which can contain in particular the generator supply, the radio transmitter and in general the electrical control organs which do not necessarily have to be in the same place where radiation is produced.
  • pairing is carried out by connecting the control device of the invention to local generator control device. At this moment distance from the two devices is not useful and the connection itself can possibly cause the initial communication of the two codes.
  • the pairing instruction over the air between the local generator control device and device control.
  • One can in particular avoid any connection by wire or mechanical by detecting the proximity of the two devices, for example by the intensity of reception due to proximity. You can also use a infrared radiation for this purpose.
  • the transmission between the generator and control device is rendered inoperative if the codes do not identify with those of pairing.
  • transmission means both transmission to departure of the generator than that towards this one. It's that means which provides the best guarantees so that only messages specific to the control device couple - generator are taken into account although we have however of the possibility of maintaining these guarantees when assigning another controller to a generator or another generator to a device order determined.
  • the present invention also relates to a installation for implementing the process, comprising conventionally a radiation generator ionizing and remote control.
  • the generator and the remote control are each provided with a transmitter and a memory for recording and transmission of a generator code and a code specific to its connection with the order.
  • the installation comprises a link-specific code modification device generator - control activated when a new generator - control pair. At this moment order is no longer conditioned to manage another generator.
  • the device for modification is a device for adding to the previous code of a specified number.
  • the generator and control have connectors can be connected by a cable for communication initial of the two codes between the generator and the command.
  • This cable is intended only for communication initial: it can be simple and very short and it does not in no way reduces the benefits of the wireless link according to the invention.
  • the generator assembly - control comprises a pairing member actuating the link-specific code modification device generator - control.
  • the matching unit acts automatically during placement of the control near the local control device of the generator.
  • the generator and the control are provided with means for recording and transmission of a code specific to the order.
  • the generator and control are provided with means to render ineffective any communication to except for the initial transmission after the constitution of a new generator couple - control if said communication does not include the latest codes saved.
  • the first transmission of two codes come from the generator. It is indeed the safest way to record the code for the error-free generator, which can be stored therein from its manufacture.
  • control is provided, at maximum at a short distance, from a detector measuring the importance of the radiation which reaches it.
  • the detector includes an alarm designed to intervene when the radiation dose received exceeds a threshold warning.
  • said detector is connected to means for transmitting a signal causing the stopping of the generator.
  • the present invention can advantageously be applied in both medical uses than industrial ionizing radiation. She allows to free from any electrical or mechanical connection between the generator and its control, except in certain cases (essentially to establish the initial codes at the time pairing).
  • Figure 1 shows very schematically all the means enabling control and security of an X-ray generator.
  • the control device 1 is the place where the operator stands and intervenes for manage the X-ray generator 2.
  • the operator has a screen 3 where the various measurements performed appear in particular by the X-ray detector 4, which is here a Geiger counter, which informs him of the radiation dose he is undergoing, warns him if the dose becomes large and, via command 1, stops the generator from authority when the dose exceeds a critical threshold. Therefore, it is especially impossible to operate if command 1 is too close to generator 2.
  • Command 1 communicates with generator 2 over the air via radio transmitters 5 and 6. This communication takes place in both directions for the generator management and for data transmission from the generator to control 1 and screen 3.
  • the generator can understand not only of the generator itself, but also proximity, the local control device 7 which contains the power supply of the generator itself and the various electrical components which must not must be placed where the radiation is produced.
  • Command 1 and the local device control 7 contain the memories where the codes as described above. These codes are used to each transmission, whatever its direction, between the command 1 and generator 2.
  • the code specific to the link is incremented with each new pass, i.e. when the generator is associated with a new ordered. Instead of incrementing, we can also use a random code each time.
  • Pairing is caused either by an action manual, either by a contact acting when the control 1 is placed against or on the local control device 7, either by radio or by placing a cable (not shown) between these two devices, said device cable only used for pairing. It's through him that the codes are transmitted to the commands during pairing.
  • Pairing is only necessary during a change of generator - control pair.
