[0025] like Figure 1-3 As shown, the utility model proposes an integrated keyboard suitable for an independent termination system of a neutron therapy device, and the integrated keyboard includes:

[0026] A housing 1, wherein a standard keyboard area 2 and a special keyboard area 3 are provided on the upper surface of the housing 1;

[0027] A key printed circuit board 4 and a transmission printed circuit board 5, wherein the key printed circuit board 4 is connected to the transmission printed circuit board 5 via a flat cable 6; the standard keyboard area 2 and at least part of the special keyboard area 3 are connected to the key printed circuit board 4, and the special keyboard area 3 includes a beam-out enabling key switch 7, and the beam-out enabling key switch 7 is connected to the transmission printed circuit board 5.

[0028] In this embodiment, in order to solve some drawbacks of the independent use of the dedicated keyboard and the standard keyboard in the prior art, a technical idea of ​​combining the standard keyboard and the dedicated keyboard is adopted, and an integrated keyboard suitable for the independent termination system of the neutron therapy equipment is proposed. Specifically, two circuit boards are installed inside the keyboard shell 1, namely a key printed circuit board 4 and a transmission printed circuit board 5, and the two circuit boards are connected by a flat cable 6, wherein the key printed circuit board 4 is connected to the standard keyboard area 2 and part of the dedicated keyboard area 3, and a beam-out enabling key switch 7 is provided in the dedicated keyboard area 3, which is connected to the transmission printed circuit board 5. After the beam-out enabling key switch 7 is turned on, the dedicated keyboard area 3 can enter the working state for use. After the beam-out enabling key switch 7 is turned on, the dedicated keyboard area 3 enters a locked state and cannot be used, while the standard keyboard area 2 can be used normally. Through the above scheme, the keyboard placement space can be simplified. Compared with two independent keyboards, the keyboard can always be used, which improves the utilization rate and simplifies the operation. The problem of misoperation is also avoided by setting the beam-out enabling key switch 7.

[0029] Exemplarily, the transmission printed circuit board 5 is an input / output I / O interface board, which can realize communication connection with the host computer and the subsystem. The cable 6 adopts FC cable 6, and the two ends of the cable 6 are connected through a wire-to-board connector. A flat ribbon cable (Ribbon Flat Cable) can also be used to realize the connection between printed circuit boards, and an FPC flexible circuit board can also be used to realize the connection between printed circuit boards. It should be noted that the present utility model does not limit the physical realization and contact method of the button, such as a tact switch (Tact Switch), a carbon film button, a membrane button Metal Dome, a silicone button, etc. can also be used.

[0030] Furthermore, the dedicated keyboard area 3 also includes a motion enabling key 8 , and two motion enabling keys 8 are provided. Both of the two motion enabling keys 8 are connected to the key printed circuit board 4 .

[0032] In order to further improve the safety of operation, two motion enable buttons 8 are provided, and the two buttons are in a logical relationship of an AND gate. Therefore, only when the motion enable buttons 8 are pressed at the same time and the AND gate logic is judged as "1", the motion enable button 8 can be effective. The above arrangement can also effectively prevent the operator from triggering it by mistake, causing the treatment bed to move during the treatment process and causing damage to the patient.

[0033] It should be noted that the utility model does not limit the logical implementation method of the motion enable button 8. For example, a simple series connection method can be used to implement the "AND" logic of the two buttons, or the button I / O output level can be collected and the "AND gate" logic chip can be used to obtain the final combination state of the two buttons.

[0034] Furthermore, the housing 1 is also provided with an Ethernet port 9 and an external cable connector 10 , and both the Ethernet port 9 and the external cable connector 10 are connected to the transmission printed circuit board 5 .

[0036] For example, the external cable connector 10 may be a DB25 model, or may be a DB15 or even a DB9 model according to the number of external I / Os. Similarly, the present invention does not limit the contact type of the connector.

[0037] Furthermore, the dedicated keyboard area 3 is also provided with a clear interlock key 11 , and the clear interlock key 11 is connected to the key printed circuit board 4 .

[0038] Based on the above embodiment, the dedicated keyboard area 3 is also provided with a clear interlock button 11. During operation, the host computer will detect whether the radiotherapy equipment is in an interlock state. If the equipment is in an interlock state, the clear interlock button 11 is pressed and the radiotherapy equipment will be initialized.
