The present invention relates to a communication technology between the military management unit and the platform device, the military management unit and each unit, each unit and the platform device in the military management elevator system, in particular, the communication line between the platform device and the car and a central processing unit It relates to a communication relay device of the military management elevator that allows the communication between the car and the platform and to continuously control the platform apparatus regardless of the failure of the main central processing unit of the military management department.

1 is a block diagram of a communication station of a military management elevator according to the prior art, and as shown therein, communicates with each unit control unit 102, 103 through an exhalation network NET1, NET2, and each unit. A military management unit 101 for grasping a driving state and selecting and assigning an airplane in an optimal driving condition when a platform call signal is input from an arbitrary floor through the platform network NET3; In addition to performing a unique breath control function, it outputs the location information inside the car through the platform network NET4, and the arrival and forecast lamps 102A-102N installed on each floor through the platform network NET5. An exhalation controller 102 for controlling lighting; It is connected to the platform network (NET3) consisting of the landing button (104A-104N) to receive the call request by the user on each floor and to indicate whether the call registration in the up, down direction, the operation of the following Same as

Military management unit 101 communicates with each unit control unit 102, 103 through the main central processing unit (CPU1) and the exhalation network (NET1), (NET2) and the data received from them. Register on the base and learn about the operating status of each unit.

In such a state, when a passenger waiting on an arbitrary floor presses a corresponding button among the platform buttons 104A-104N and inputs the platform call signal, the call signal is centrally processed by the military management unit 101 through the platform network NET3. Is passed to the device CPU2. Accordingly, the military management unit 101 registers the platform call signal, selects a flight in an optimal driving condition based on the learning result, gives an assignment command to the corresponding flight, and calls through the path. Since the registration signal is output, the lamp of the corresponding button among the landing buttons 104A-104N is turned on so that the user recognizes that the call requested by the user is registered.

Thus, the exhalation assigned above will run towards the floor where the call occurred. At this time, for example, if the exhalation control unit 102 of the exhalation control unit 102, 103 corresponds to the control unit of the selected exhalation, the exhalation control unit 102 to display the location information of the car on the indicator inside the car Outputs the floor information through the platform network NET4, and on the other hand, the platform network NET5 to inform the arrival and forecast of the car through the arrival and forecast lamps 102A-102N installed on the platforms of each floor. It outputs the lighting command signal.

For reference, the arrival and forecast lamps 102A-102N are connected to the platform network NET5 through respective input / output lines.

However, in the conventional military management communication device as described above, since the arrival and the forecast lamps of each unit and the platform are connected through the input / output line, the number of the input / output boards increases as the number of floors increases, which leads to an additional cost. If the main central processing unit in the military management unit does not operate normally because of an abnormality in the management unit, the communication line between the car and the platform is separated, so that the call generated from the platform cannot be registered, and the car is displayed through the display device of the platform. There was a defect that could not display the location information of.

Therefore, the technical problem to be achieved by the present invention is to connect the communication line between the platform and the car in one network, and one central processing unit in the military management unit communication relay of the military management elevator to communicate with the car and platform devices through the network In providing a device.

It consists of platform buttons (205A-205N) that indicate whether or not call registration.

3 is a block diagram of an exemplary embodiment of a communication relay device for a military management elevator according to the present invention. As shown therein, the allocation information and the forecast information transmitted from the military management unit 201 to each unit are included in the military management bus (BUS31). And a dual port RAM 302 which is stored through the interface unit 302 and stores information transmitted from the exhalation unit or the boarding point device side; Controls communication between the military management unit 201, the exhalation network device 308, and the platform network devices 309A-309C, and integrates the platform location indication data and the arrival data transmitted from the exhalation network device 308 with the integrated network (NET31). A central processing unit (303) for transmitting to the platform network devices (309A-309C) side through; An integrated network (NET31) and an interface unit (304) connected to the central processing unit (303) for integrated management of the exhalation network device (308) and the platform network devices (309A-309C); A system monitoring apparatus 305 for monitoring a running state of the system; A ROM 306 for storing a communication control program of the CPU 303; The RAM 307 is configured to store data processed by the system. The operation of the present invention configured as described above will be described in detail as follows.

In the case where the main central processing unit of the military management unit 201 does not have any abnormality and operates normally, data transmitted from the exhalation network device 308 or the platform network devices 309A-309C is integrated into the network NET31 and the interface unit. The processor 303 transmits the received data to the central processing unit 303, which collects and reprocesses the received data, and stores the received data in a common memory, that is, the dual port RAM 302.

Through this process, the data stored in the dual port RAM 302 is accessed at predetermined intervals or whenever necessary, and is transmitted to the main central processing unit of the military management unit 201 through the interface unit 301 and the military management bus BUS31. The main central processing unit then utilizes this data as military management data.

In addition, allocation information, forecast information, and other information to be transmitted from the military management unit 201 to each unit are stored in the dual port RAM 302 through the path under the control of the main CPU and then accessed again. The interface unit 304, the integrated network NET31, and the exhalation network device 308 are sequentially transmitted to the corresponding unit.

The communication between the platform apparatus and the military management unit 201 is also performed through the above path, that is, the military management bus (BUS31) ↔ interface unit 301 ↔ dual port RAM 302 ↔ central processing unit 303 ↔ interface unit 304 ↔ platform Through network devices 309A-309C.

For example, when the forecast is to be displayed through the arrival and forecast lamps 204A-204N, unlike the related art, the control signal is delivered from the military management unit 201 to the corresponding platform device directly through the path, and thus the forecast lamp is displayed. Lights up.

As another example, when the arrival status is to be displayed through the arrival and forecast lamps 204A-204N, the location information output from the corresponding unit is displayed in the unit network 308, the integrated network NET31, and the interface unit ( 304 is sequentially transmitted to the central processing unit 303, in which the central processing unit 303 does not transmit the transmitted location information to the military management unit 201 side directly through the integrated network NET31. It is transmitted to the platform apparatus side.

However, when a failure occurs in the main central processing unit of the military management unit 201, the central processing unit 303 is the platform network location indication data, the arrival data transmitted through the exhalation network device 308, the integrated network ( NET31) and received through the interface unit 304 to be transmitted to each platform device side via the platform network devices 309A-309C, so that the control function for the platform device continues regardless of the failure of the main central processing unit. You can do it.

As described in detail above, the present invention connects the communication lines of the platform and the car to one network, and allows one central processing unit in the military management unit to communicate with the car and the platform devices via the network, thereby maintaining the main center in the military management unit. Even when a failure occurs in the processing device, it is possible to continuously perform a control function such as displaying the current car position on the display device installed in the platform or indicating arrival.
