Description: TECHNICAL FIELD The present invention relates to an improvement of a nurse call intercom system. [Background Art] In order to facilitate communication and nursing activities between patients and nurses in a hospital, a nurse call response display system using a multiplex transmission control system has been recently used. FIG. 5 shows a basic configuration of this system. The nurse station side has a plurality of display windows 203b ... As individual display operation units according to the number of patients, and the display windows 203b ... A display device 203 provided with an LED corresponding to the patient is provided, and a grip switch 20 corresponding to the patient is provided on the other hospital room side.
5 are provided, and these are connected via a multiplex transmission line 202 via a controller 201. In such a system, when a patient in a hospital room or the like calls a nurse, the LED 204b provided in the personal operating device 204 lights to indicate that the nurse is calling, and the nurse station called up corresponds to the central operating device 203. The display window 203b flashes and a buzzer sounds at the same time. The buzzer continues to ring until the nurse answers the patient's call, and when the operator operates the operation switch 203a of the individual display operating unit to answer the call, the buzzer stops ringing and the display window 203b flashes at the same time. Changes to In response to such a call, the nurse goes to the side of the patient's bed and, after finishing the work, if he operates the recovery switch 204a of the personal operating device 204, the LED 204b that was lit turns off and at the same time the nurse station Display window 203b provided on the side
Goes off, and all operations are completed. However, in such a system, the nurse station side only knows whether or not the patient is calling, and it is not possible to know what kind of condition the patient is calling. For this reason, in recent years, a system has been developed as a nurse call intercom system in which an intercom function is added to the above-described system so that a patient's requirements can be heard through a telephone call. There is also a system in which a task can be grasped by changing a ringing tone of a buzzer. However, in the case where the patient's requirements can be grasped by the ringing tone, it is necessary to grasp the type of ringing tone in advance and understand it by listening to it. It must be distinguished, and it is generally troublesome to distinguish, so improvement is desired. [Object of the Invention] The present invention has been developed in view of the above circumstances.

A transmission signal including a start signal ST, address data AD, control data CD, parity check CH, and return waiting time RD is cyclically and sequentially transmitted to each unit in the system including a nurse call slave unit B by a time division multiplexing method. When a transmission signal is transmitted to each unit in this manner, any of the nurse call slave units B in the system
Makes a call, the nurse call slave unit B returns an interrupt signal as a return signal to the return signal standby time RD of the transmission signal through the wall unit C. This interrupt signal is returned to the controller 1a via the multiplex transmission line 1, and the controller 1a receives and reproduces the received return signal and further sends it to the arithmetic control means (not shown). When the arithmetic control unit determines the interrupt signal, the interrupt mode is executed, and a signal requesting the return of the address data is transmitted, and the address data is returned from the nurse call cordless handset B which has made the interrupt. The controller 1a receiving this return signal determines the address for which the interrupt is requested, sends a return signal for calling the nurse call slave unit B at the corresponding address, and sends data during the return waiting time RD of the transmission signal. Then, the interrupt mode is canceled at the time when the arithmetic control means reads the data sent back and rewrites the data stored in the memory in the controller 1a, and the controller 1a returns to the normal mode to perform the above-mentioned operation. Access to each unit including the nurse call slave unit B is continued by the time sharing method. Then, when accessing the list display operation unit 3 of the nurse call base unit A corresponding to the called nurse call base unit B, a control signal is sent to the nurse call base unit A, and the corresponding individual display operation unit The 31 display section 3a is turned on. The lighting of the individual display operation unit 31 is performed by operating the operation switch 3c of the individual display operation unit 31 of the nurse call master unit A in response to the call, and restoring a switch provided on the wall unit C of the nurse call slave unit B on the calling side. Holds until 5c is operated. In this case, in the embodiment of the present invention, the lighting color of the display unit of the individual display operation unit 31 of the nurse call master unit A is changed according to the purpose of calling the nurse call slave unit B. The purpose of the call can be immediately determined by looking at the color. FIG. 4 is a time chart for explaining the control operation in the system of the present invention more specifically. The operation of the system of the present invention will be further described with reference to this drawing. When any one of the call switches 4a to 4c of the nurse call slave B in the system is operated, the call confirmation light 4e of the nurse call slave B is operated. Lights up (steps 100 and 101). The controller 1a discriminates the type of the call switch operated at this time (steps 102, 111, 120, 129), an emergency call mode routine for an emergency call, a normal call mode routine for a normal call, and a secret call mode routine for a secret call. , A drip invocation mode routine is executed. That is, in the emergency call mode routine, the corresponding display unit 3a of the individual display operation unit 31 of the nurse call base unit A is red LE.
