Referring to the operation of the system according to the monitoring of the alarm status of the subscriber, the node computer 12 divides the subscribers into five groups in units of 1000 subscribers, and sequentially monitors the status monitoring signals from the first to the 1000th subscribers in five groups. The subscriber terminal 18 to transmit. Accordingly, the communication control ports 13 to 5 are allocated five subscriber ports for accommodating 1000 subscribers, and the ports 6 to 8 are for the remote meter reading computer 15 and the security disaster prevention operation computer 17, and crime prevention. There will be a total of eight ports allocated for the disaster prevention company. In addition, if the status monitoring signal is sequentially transmitted from 1 to 1000 times, the search time is proportional to the number of subscribers, which makes it difficult to control in real time. Therefore, the 1000 subscribers are classified into several small groups and are commonly applied to small groups. When the status monitoring signal is transmitted and the signal of the troubled subscriber is detected, the group polling method is applied to re-investigate only the relevant small group to retrieve the troubled subscriber in real time.

In the process of transmitting data to the subscriber terminal 18, an RF modem 5 is used to transmit digital data from the node computer 12 on the coaxial network 9, and the RF modem 5 Digital data is modulated by the frequency modulation shifting method and transmitted to the coaxial network 9. The subscriber station 18 then inversely converts the RF data transmitted through the coaxial network 9 into digital data by a frequency demodulation shifting scheme. The data converted into digital data are analyzed by the central processing unit embedded in the subscriber terminal 18, and the analyzed data is collected by the central processing unit when the addresses are the same compared to the unique addresses stored in the terminal. Provide data in a prescribed format. The data provided as a response are transmitted back to the node computer 12 via the RF modem 5, and the node computer 12 analyzes the received data and transmits the data to the node computer 12 when it is determined to be alarming data and situation change data. It is transmitted to the printer 11 and the crime prevention disaster management computer 17 connected. The data transmitted from the node computer 12 to the crime prevention disaster prevention operation computer 17 is compared with the registered status of the alarm sensor for each subscriber registered inside the crime prevention disaster prevention computer, and the type of alarm is determined, and the status of the alarm is changed according to the alarm status. After categorized by category, the subscriber history and related history data already built on the screen are displayed on the screen.

According to the menu selection method displayed on the screen according to the type of alarm, the operator operates the emergency contact means to the relevant institutions such as police station, fire department, hospital, and other public offices, and inputs the operator's bookkeeping details that occurred in handling the alarm. The alarm-related work is performed in accordance with the predetermined alarm processing order, and the execution result is sent to the node computer 12. The node computer 12 selects the data requiring notification to the subscriber according to the processing result, and then the selected data is stored in the subscriber terminal 18. Upon receiving the data, the subscriber terminal 18 analyzes the contents of the data to indicate the situation processed by the node computer 12 and the crime prevention computer 17, or to display a beep tone.

If the data received from the node computer 12 is an armed or released signal of a sensor installed in the subscriber's home, the data is stored in the state change file of the subscriber and used for analysis of the received alarm later.

Next, referring to the operation of the system according to the remote meter reading, when the remote meter reading operator wants to read the meter, the meter reading menu is selected among the main menus on the remote meter reading computer 15, and then the desired meter reading among the sub-menus of all subscribers, meta, and subscribers is performed. Select. According to the selected menu, the remote meter reading computer 15 transmits the meta number, subscriber number, and meter reading request signal to the node computer 12 for the meter reading. The node computer 12 sends the meter reading request message to the corresponding subscriber terminal 18 through the RF modem 5 according to the meta number and the subscriber number, and the subscriber terminal 18 sends the meter reading request message of the meta matcher. The meta matcher 19 transmits the data obtained by integrating the information from the meta 20 to the subscriber terminal 18 by the meter request message. Subscriber terminal 18 stores various meter reading values sent from the meta matcher 19, and sends the meta meter reading value as response data when the node computer 12 pulls its own address. In addition, the node computer 12 classifies the data answered during polling, and transmits the data classified as the meter reading data to the remote meter reading computer 15.

2 is an overall process flow chart according to the operation method of the security and disaster prevention and remote meter reading system to which the present invention is applied.

First, look at the process of the crime prevention, initialize all the equipment (21) and turn on the various sensors (22). Continue to investigate whether one of the sensors is operating or the subscriber has pressed the keypad for reasons of disaster or outsider penetration (23). If the keypad or sensor is detected, the subscriber terminal (18) detects it and the node computer The alarm signal is sent to (12), and the alarm status is displayed on the subscriber terminal 18 (24, 25). The node computer 12 displays the alarm status on the screen and prints the alarm status (26). The alarm generating subscriber number and the alarm number data are transmitted to the disaster prevention operation computer 17 (27).

Then, the security disaster prevention operation computer 17 transmits the response data for the alarm to the subscriber terminal 18 through the node computer 12, and is stored in the received subscriber-specific, situation-specific data and its own auxiliary storage device. By comparing the data on the installation of various sensors installed in the subscriber's premises, the data of the situation change received are various sensors and devices installed in the subscriber's premises such as fire alarm, gas leakage alarm, theft alarm, intrusion alarm, or the subscriber presses the picad. If it is a crime prevention alarm by grasping the operation status of CAD, the operator operates emergency contact means such as police station, fire department, hospital, or other public office in accordance with the option tag displayed on the screen according to the type of alarm. To perform alarm related tasks in accordance with a predetermined alarm processing sequence, such as inputting an operator's notes. If the subscriber presses the keypad to signal the arming or releasing of the sensor installed in the subscriber's premises, the subscriber records the state in the subscriber's status change file (28), and the subscriber terminal 18 displays the alarm response data transmitted. When the alarm release data is transmitted from the disaster prevention operating computer 17, the release state is displayed and returned (29 to 31).

Next, referring to the processing procedure for the remote meter reading, the meta-matcher 19 converts the pulse generated by the power meta after initialization into a meta value and accumulates the data (22). When the remote reading request signal is transmitted from the remote metering computer 15 to the node computer 12 to the subscriber terminal 18 (23), the subscriber terminal 18 examines the metering data accumulated in the meta-matcher 19. And transmits the meter reading value, the unique number and the meta number value to the node computer 12, and the node computer 12 classifies it into the metering data among the various data received and organizes it into a unique number, the meta number and the metering data, and then reads the remote metering computer. Transfer to (15) (32). The remote meter reading computer 15 stores the received data in the auxiliary storage device, prints it to the printer 14 when the operator requests the preparation of the bill and the account book, and finishes.

3 is a flowchart of a method of operating the node apparatus 1 according to the present invention, which shows a processing procedure by a control program mounted and executed in the node computer 12.

The node computer 12 is installed in a central management center to perform polling of subscribers to monitor crime prevention and remote metering data from all subscribers, and to collect and classify various types of data transmitted to subscribers and to switch messages to necessary ports. Will be performed.

When the power source of the computer is first input, after confirming the state of the main memory device, the program for controlling the communication control port 13 and the program of the main computer are executed. The communication control port 12 uses a 'RIC card', a product of IBM Corporation, and when the program of the communication control port 12 starts to run, first, through the five subscriber ports, the subscriber status according to the registered subscriber address. Input and output data for monitoring. If the subscriber data is not registered at this time, the subscriber port is not operated.

When the program of the main computer starts to run, the ports for the crime prevention disaster prevention computer, the remote meter reading computer, and the transfer to SK-9000 protocol are operated and the operator log ON menu is displayed on the screen. At this time, when the registered operator password is registered, the main selection menu of the main computer appears, and when the subscriber status menu is selected from the main menu, subscriber status monitoring data received through the communication control port 13 is displayed on the screen. When the status change data from the subscriber port is input through the communication control port, the host computer analyzes the input data, prints the status data, displays the status on the screen, and the crime prevention disaster prevention operation computer (17) port for the crime prevention disaster prevention data. It transmits data by switching to the port for SK-9000 protocol conversion transmission.

The data input through the port for the crime prevention disaster prevention operation computer 17 is classified by type, and in the case of subscriber registration, it is stored in the main memory of the main computer and the communication control port 13 to add subscriber status monitoring. In the case of the alarm status processing, the data is analyzed again to change the status display screen of the host computer and at the same time, the data is output through the subscriber port of the communication control port 13. When the meter request signal from the remote meter computer 15 port of the communication control port 13 is input, the host computer outputs the meter request data through the corresponding subscriber port. Switch data to the port.

Now, a detailed processing procedure will be described with reference to the illustrated flowchart.

When the program is executed, the value controlling the communication control port 13 (original interrupt vector) is stored, and the main computer control value (new interrupt vector) is stored (40, 41). Then, the subscriber registration file is read, and a buffer for storing the status of the subscriber terminal 18, remote reading request data, and a retention value for screen color specification are initialized (42 to 45). Then, the operator registration status for the operator is read, and the main menu is displayed on the screen after confirming that the registered operator's unique number and the operator's name match that of the logon worker (46 to 48). A message (49) is sent to the printer 11 indicating that the system has been operated, and it is checked whether the timer is initialized (50). If the timer is not initialized, it initializes the timer (51), and checks the subscriber 30 minutes after the timer is initialized to check the communication with the subscriber is lost, and removes the subscriber's remote meter reading request message ( 53).

Then, in order to print various messages, it is checked whether the printer buffer is empty (54). If it is not empty, the printer 11 is determined to be normal (55). If the printer buffer is normal, the printer is canceled and the contents of the printer buffer are printed. 56) If it is not normal, a transmission pending state is set to prevent loss of data to be printed (57).

Next, the operator checks whether the user inputs the key (58), if there is a key input, performs a menu corresponding to the key input (59), and identifies the port number for the current status of the subscriber ports assigned to the communication control port 13. Is designated as 1 (60), and the subscriber status registered in the port number 1 is examined (61). If there is no registered subscriber, the subscriber port is increased by one (73). If there is a registered subscriber, set it to the first group (62), poll (63) the status monitoring signal for that group, examine the transmission buffer (64) if there is a message to be sent to the subscriber, and transmit (65) the message. If there is no message transmitted from the subscriber, it is determined whether there is a message transmitted from the subscriber (66). If the data is classified, it is classified (67) and stored in the reception buffer (68). 69, 70), the group number is increased by one (71).

If the group number has exceeded the last group number (72), and the subscriber port is increased by one (73), and if it is not exceeded, until the polling for all subscriber groups connected to the corresponding port is completed (63) to ( Repeat the process up to 72).

Thereafter, the above steps 61 to 73 are repeatedly performed to perform registered subscriber processing while increasing the value from port 5 to 1 for the data processing of ports 1 to 5 assigned to the subscriber among the communication control ports 13. If the port number is greater than 5 (74), the receiving buffer is examined (75), and if there is data related to the device connected to the corresponding port (security prevention operation computer or remote metering computer), this signal is sent to the corresponding port (76). If there is outgoing data from the device connected to the port (security prevention operation computer or remote meter reading computer) (77), the data is stored in the sending buffer (78), the port number is increased by one (79), and the port number is examined. (80). If the port number is less than 8, the process from (75) to (80) is repeated, and if the port number is greater than 8, the process returns to the process of initializing the timer (50) and performs the process again.

Therefore, the present invention carried out by the above-described processing procedure, there is an effect that it is possible to perform a crime prevention and remote metering function using a bidirectional CATV network with a fast processing speed and high reliability.
