Abstract

PROBLEM TO BE SOLVED: To reject control commands from a wrong remote control switch when switch controlling is performed in combination with a different remote control switch and a different controller. SOLUTION: When jumper lines J1, J2, and J3 are selectively connected in a specified combination to jumper line connection terminals 16 to 18 in advance, IDs are set for a near switch 11 corresponding to beds with different control functions, an ID for the near switch 11 is read by a controller 12 and determined if this ID is a specified ID, and based on this judgement, whether a control signal from the near switch 11 is accepted or not is determined to control the bed movement.

On the other hand, the data lines DATA1, DATA2, DATA3 and DATA4 are connected to the cathodes of the diodes D1 to D4. The cathodes of the diodes D1 to D4 are connected to the cathodes of the light emitting diodes LED1, LED2, LED3, and LED4, and the LED lines are connected to the anodes of the light emitting diodes LED1 to LED4. One terminal side of jumper line connection terminals 16, 17, 18 is connected to the anode side of the diodes D2, D3, D4, and a third energizing line SEL3 is connected to the other terminal side of these jumper line connection terminals 16-18. I try to connect.

The jumper wire connection terminals 16 to 18 include:

In the controller 12, although not specifically described here, a control procedure (firmware) is incorporated for each bed having a specific operation adjusting function, and an ID corresponding to the bed is provided. It is equipped with a means for collating numbers. That is, in the firmware, when a signal from the matching unit matches a specific ID number, it is determined that the operation is from a predetermined hand switch, an operation command is accepted, and power supply control is performed to a specific location according to the operation command. On the other hand, if it is different from the specific ID number, power is supplied to operate a specific portion of the bed according to the operation command, and if it is different from the specific ID number, all operation mechanisms The power supply to the switch can be cut off so that all operation commands from the hand switch are not accepted.

Since the electric bed control system having the remote controller switch identification function according to the present invention is configured as described above, it is suitable for the bed, that is, the control is performed only by the connection / non-connection of the jumper lines J1, J2, J3. -La 12
Can be set in advance to a specific ID number suitable for
Since only jumper wires are added to the current hand switch, the manufacturing cost can be minimized. Further, the controller 12 has no change in the circuit, and can respond by changing the control program, so that the cost can be further suppressed.

[0014]

As described above, according to the present invention, even when remote control switches of different models are connected to adjust the operation of a specific part of the bed, the remote controller is combined on the controller side in the electric bed control system. It is possible to identify whether or not the remote control switch is suitable, and if it is, it is possible to adjust the operation of a specific location in accordance with the operation command, while it is determined that the operation is different. when,
Since only a specific part is operated as instructed or an instruction is completely not accepted, at least operation of different parts of the bed can be prevented, which can greatly contribute to safety. In addition, since a simple identification means is added and the identification is simply performed on the controller side, an increase in manufacturing cost can be suppressed.
