DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION In order to perform optimum maintenance, the present invention records the operation time and the number of times of operation for each bed so that maintenance and inspection can be performed when the number of times reaches a predetermined time. The present invention relates to an operation control system for an electric bed having an operation recording function.

2. Description of the Related Art Recently, not only hospitals but also home beds have been widely used which are provided with an electric floor undulating mechanism. According to such an electric floor undulating mechanism, since the floor tilting operation and the elevating operation are performed by electric power, the labor can be greatly reduced as compared with the manual floor undulating mechanism. effective.

[0003]

However, in order to use the electric floor undulating mechanism in a safe manner for a long period of time, as in the case of other equipment, it is necessary to carry out periodic maintenance and inspection. Is desirable. However, there is a great difference in the frequency of use of the electric operation depending on the functional level of the user and the opportunity for nursing care, and the degree of wear of the mechanism is different. Therefore, it is meaningless to determine the period of the periodic inspection uniformly. Therefore, the inventor has recorded that the operation time and the number of times of the electric operation for each bed are recorded, and if maintenance and inspection are performed based on the recorded data, it will be possible to perform optimal maintenance according to the use state. The present invention has been proposed based on such a viewpoint, in order to perform optimal maintenance, for each bed, the operation time, the number of operations is integrated and recorded, so that these records can be read out as appropriate, An object of the present invention is to provide an operation control system of an electric bed having an operation recording function, which can reliably determine that maintenance and inspection should be performed based on these records.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of an operation control system for an electric bed provided with an operation recording function according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram showing an operation control system of an electric bed having an operation recording function. Such a system,
1 shows a configuration of a controller 1 mounted on a control box (not shown) mounted on a frame or the like below a bed floor. The bed in this case is provided with, for example, a back raising mechanism, a knee raising mechanism, and a floor elevating mechanism.

[0006] The controller 1 includes a microprocessor 2 (hereinafter, MPU 2) and has a nonvolatile storage element 3. The MPU 2 is provided with a remote control switch 4 (hereinafter, referred to as a switch) which can be operated on the floor.
An operation signal is taken from the hand switch 4), and power is supplied to the motor 6 for raising the back, the motor 7 for raising the knee, and the motor 8 for raising and lowering the floor via the motor switching unit 5 for supplying / cutting power to the motor. The operation is controlled.
Further, the MPU 2 measures the energizing time to the back lifting motor 6, the knee raising motor 7, and the floor elevation motor 8 based on the reference time generating means 9, and calculates the operating time of each motor from the energizing time. It has a function of integrating, integrating the number of operations from the number of energizations, and accumulating the integrated data in the nonvolatile storage element 3. Further, the MPU 2 may receive other information such as an interruption of operation due to an overload, a motor 6
It is also possible to record information such as the suspension of operation due to a malfunction of the controller 1 or 8 or the like. The history data of these electric operations can be transferred from the serial interface 10 to an external device (for example, a recording and display device, a measuring device).

In the operation control system of the electric bed having the operation recording function as described above, the user operates the hand switch 4 to give an operation signal to the MPU 2 of the controller 1.
The control command from the MPU 2 is supplied to the motor switching unit 5,
Power supply control is performed to the motor 6 for raising the back, the motor 7 for raising the knee, and the motor 8 for moving the floor up and down. At this time, the MPU 2 determines the energizing time (operating time) and the number of energizing times (operating times) of the fed motors out of the motor 6 for raising the back, the motor 7 for raising the knee, and the motor 8 for moving up and down the floor, as a reference time generating means. 9 and accumulates the accumulated data in the non-volatile storage element 3. Since the integrated data is stored in the non-volatile storage element 3 as described above, the integrated data can be retained without being lost even if the power is shut down due to the stop of the operation. Then, the integrated data can be transferred from the serial interface 10 to an external display device or measuring device and output and displayed as operation history data. Based on these data, it is accurately determined whether or not maintenance and inspection should be performed. can do. In addition to the energization time (operation time) and the number of energization times (operation times) as described above, the MPU 2 also stores non-volatile information such as interruption of operation due to overload, and interruption of operation due to a failure of the motor 6 to 8 or the controller 1. Since the information can be stored in the sex storage element 3, information corresponding to those inconveniences can also be grasped by an external display device, so that a quick recovery action can be taken and optimal maintenance can be performed. In this way, even if there are many beds with similar functions, each with different usage status and degree of wear,
It is possible to accurately grasp the state of the bed from the accumulated data of the operating time and the number of times of operation individually, and to perform more optimal maintenance, and it is possible to perform maintenance inspection work without hassle and without waste Become.

[0008]

According to the present invention, it is possible to perform maintenance according to the use condition and the degree of wear of the bed, it is possible to perform a proper maintenance inspection without waste, and it is possible to reduce the maintenance inspection cost. .
