Known is a device for remote access to a personal computer disclosed in US patent application No. 2007208891 from 06.09.2007. This device includes: the PC of the engineer, which contains, in turn, the system unit of the engineer, the monitor of the engineer, a keyboard and mouse, the PC of the client, which contains the system unit of the client and the monitor of the client, a keyboard and mouse, the control and monitoring device, which contains the communication module , emulation module, video capture module, processor module, data exchange bus, and Internet communication channel.

The control and monitoring device contains a peripheral device module (KVM controller unit) - it combines a module for receiving and converting a vga signal and a module for emulating keyboard and mouse signals, a data exchange bus;

the processor module also contains RAM - memory for the processor; signal converter - monitors the inclusion of a computer to automatically enter the BIOS, a module for working with a wired communication network (linking apparatus), network - a data transmission network, for example, an internal local area network, while the Internet is logically separated from it.

The disadvantage of this device is the impossibility of using this device to control and monitor the state of the MRI device, another disadvantage is the low reliability of this system, due to the use of only a wired communication channel with the engineer's computer.

The closest device is the control device described in RF patent No. 2447491, this system is similar to that described above for US patent application No. 2007208891 and includes a control and monitoring device made in the form of a KVM over IP unit, a client communication unit, a server communication unit and a personal service engineer computer. In this case, the communication unit uses a wireless communication channel, for example, a 3G network.

The disadvantage of this device is the impossibility of using this device to control and monitor the state of the MRI machine.

The tasks that the present invention solves are monitoring the parameters of the MRI device in real time and the ability to control the MRI device from a remote device of a service engineer.

The technical result is to simplify the maintenance and control of parameters of the MRI apparatus by a technician.

The technical result is achieved by the fact that the device for remote control and monitoring of the magnetic resonance imaging (MRI) apparatus includes a control and monitoring device made in the form of a KVM over IP unit, a client router, a server router and a personal computer of a service engineer.

At the same time, the control and monitoring device is made in the form of a single housing with connectors for connection to an MRI device, and includes:

- KVM over IP unit, which is installed between the workstation of the MRI machine and the MRI monitor through the housing connectors,

- a unit for monitoring the parameters of the MRI device, connected to the MRI compressor, through the housing connectors,

- a client router connected to the KVM over IP unit and the unit for monitoring the parameters of the device, which receives and transmits data from the MRI device via Internet communication channels to the server router to which the personal computer of the service engineer is connected,

- a wireless transceiver associated with the client router and which is capable of wireless communication with at least one electronic device of the service engineer and

- Power Supply.

In addition, the unit for monitoring the parameters of the MRI apparatus is made in the form of a microcomputer capable of reading the parameters of the MRI apparatus through diagnostic channels, and also includes a humidity and pressure sensor connected by the microcomputer.

Also, the wireless transceiver is preferably a 3G modem.

The service engineer's electronic device can be a smartphone or tablet or computer.

The stated solution is illustrated by Figures 1-3, where:

in fig. 1 shows a general diagram of the proposed device,

in fig. 2 shows a diagram of the operation of the control device for the MRI machine,

in fig. 3 shows a diagram of the operation of the device for monitoring the parameters of the MRI apparatus.

Design:

The client device is a plastic case. It contains a KVM over IP unit, a router, a unit for monitoring parameters of an MRI device, and power supplies. In this case, the unit for monitoring the parameters of the MRI device can be made in a separate case. The connectors are located on the front panel.

The MRI cryosystem monitoring unit is a plastic case with a microcomputer, a 5 / 24V power supply, and a relay. The connectors are located on the front panel.

The proposed device for the remote control of a magnetic resonance imaging (MRI) apparatus consists of:

1. KVM over IP block. D-link DKVM-IP1

2. Microcomputer Raspberry Pi

2. Router Mikrotik RB951Ui-2HnD (client)

3. 3G modem Huawei E3372h-153

4. Router Mikrotik RB951Ui-2HnD (server)

Functional Description:

Connection to the MRI device is carried out via USB, VGA interfaces. The KVM over IP unit is installed between the MRI workstation and the MRI operator's monitor. The analog video signal enters the KVM and is digitized for transmission over TCP IP networks. The maximum resolution of the transmitted image is 1600x1200. KVM also broadcasts the video signal to the monitor of the MRI machine operator. The MRI workstation is controlled by emulation of input devices. The KVM over IP block emulates the operation of a mouse and keyboard and controls the workstation of the MRI machine via the USB interface.

The KVM over IP block has its own web interface. To access it, a KVM communication channel is implemented - router - VPN - router - PC. The KVM unit is assigned a static IP address and is included in the internal network of the client router located in the remote diagnostics unit. KVM and router are connected via ethernet interface. The external interface of the router is connected to the Internet via the ethemet and / or 3G interface. The router establishes communication with the server router via a VPN network. VPN network is implemented based on OpenVPN using SSL certificates. The sha1 authentication method. The encryption method blowfish 128. Within a VPN network, all devices are assigned static IP addresses.

The service engineer's PC is connected to the internal network interface of the server router. Ethernet connection interface. A service engineer connects from his PC to the KVM unit via a web interface and performs manipulations on the MO.

The MRI cryosystem monitor is connected to the compressor via the MRI device parameters monitoring unit via the DB25 diagnostic port. The removed parameters are processed on the Raspberry Pi microcomputer and transmitted via the VPN connection to the mobile application, or in the event of an accident, an SMS is sent via a 3G modem. SMS is sent via SMS API. To transfer the cooling of the helium compressor of the MRI apparatus to the central water supply, a three-position electric tap is installed in the water supply system. The microcomputer, depending on the need, supplies 24 V power through the relay to open or close the tap. A temperature and humidity sensor is also used to control external parameters. The readings from it can avoid problems with overheating of all devices located in the technical room.
