Description

Self alarm and notification method when duplicate ID of household equipment in unmanned security system

The present invention relates to a method of recognizing a duplicate device ID (I.D) in a bus-type unmanned security system, and more particularly, to a method of notifying the guard room of the duplicate device ID when the ID device overlaps, and sounds the alarm itself.

In the bus-type unmanned security system, a plurality of household devices are connected to one guard room device, and the guard room device communicates data with the household devices in a polling manner. In the polling method, a computer or a terminal control device inquires of a plurality of terminal devices sequentially, and instructs the terminal device to start transmission when there is a request. The transmission control method inquired.

That is, the guard room device transmits the data frame including the ID of the household device that wants data communication. In the household device, when the ID included in the data frame is the same as its ID, the guard room device analyzes the data and sends the response data to the data. To send.

In the related art, when the guard room device communicates with the household devices in the polling method, if the plurality of household devices are set to the same ID, the plurality of household devices simultaneously receive data transmitted from the guard room device. do. In addition, since the plurality of household devices simultaneously transmit response data to the guard room device, the guard room device does not determine the household device to communicate with, causing a system malfunction.

In addition, since the generation device does not have a function of determining whether there is another generation of duplicate IDs, there is a difficulty in determining whether IDs of multiple generation devices are duplicated.

Accordingly, an object of the present invention is to provide a method in which a generation device can determine ID duplication in itself in a bus type unmanned security system.

Another object of the present invention is to provide a method in which a generation device sends an alarm sound by itself when IDs overlap in an unmanned security system of a bus method.

Still another object of the present invention is to provide a method of notifying a guard station device of a duplicated state by a generation device when IDs overlap in an unmanned security system of a bus method.

In the unmanned security system to achieve the above object, when the ID of the household device is duplicated, the self-alarm and notification method checks whether initial data is received from the guard room device when the household device is turned on, and when the initial data is received. Displaying no ID duplication generation in the memory and displaying the ID duplication generation in the memory when the reception of the initial data is not checked; and accessing the memory when ID duplication check data is received from the security equipment. Checking whether the ID duplication is checked, transmitting data about the ID duplication when the ID duplication is checked, and checking whether the guard room is called, and whether the ID duplication of the memory is duplicated when the guard room call is checked. When the ID duplication is checked by checking the three It characterized the device is constituted by any process which sends out the alarm itself.

2 is an operation flowchart according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a busless unmanned security system according to the present invention.

The configuration of the system is largely composed of guard room equipment 1 and a plurality of household equipment 2 (2a-2n). The guard room device 1 and the plurality of household devices 2 (2a-2n) are connected to a common data line 30 and a call line 31.

Herein, the generation device 2 will be described. The control unit 21 controls the communication with the guard room device 1 and controls the overall operation of the generation device 2 to provide various services to the user. The memory 22 includes a ROM for storing programs and initial service data for performing various functions, and a RAM for temporarily storing data generated during program execution. The memory 22 stores data regarding ID duplication according to the present invention. The alarm sound generator 23 accesses the memory 22 under the control of the controller 21 and transmits an alarm sound when ID duplication is checked. The handset 24 is connected to the handset 28 of the guard room device 1 via the call line 31, and performs a voice call between the generation device 2 and the guard room device 1. The generation device ID setting unit 25 is composed of key metrics having a plurality of numeric keys, and provides the control unit 21 with ID data generated by a user's key input. The guard room call button 26 is pressed when the guard room is called. The data transmission / reception unit 27 provides data received from the control unit 21 to the data transmission / reception unit 29 of the guard room device 1 via the data line 30, and provides data received from the guard room device 1 to the control unit 21.

Hereinafter, an example of data communication between the guard room device 1 and the generation device 2 will be described.

The guard room device 1 and the generation device 2 performs data communication in a polling manner at a transmission rate of 9600 BPS using a universal synchronous transmitter (UART).

The data communication is transmitted and received in units of frames using 5 bytes BYTE as one frame, and the configuration of the data bytes will be described below.

Firstly, start bit (1 bit; low) indicating the beginning of data, data bit (8 bit) in which data actually transmitted and received are stored, and parity bit (using RB8 / TB8) to maintain the accuracy of data transmission; It consists of a stop bit (1 bit; high) indicating the end of data. The RB8 / TB8 does not have a parity check function, and the first byte is set high and the second byte is set low in a transmission / reception data frame consisting of 5 bytes.

Hereinafter, the configuration of the data frame actually transmitted and received between the guard room device 1 and the generation device 2 as follows.

First, the data frame transmitted from the guard room device 1 to the generation device 2 will be described. The first byte stores the ID of generation device 2 that will receive the data frame. In the present embodiment, it is assumed that the ID of generation device 2 is 1 to 60 (81H-BCH), except that bit 7 is always set. The second byte stores the data to be sent, and the third and fourth bytes are always set to 00H. The fifth byte stores the path number (PATH NO) in the high nibble 4 bits and the check sum in the low nibble 4 bits. Here, the path number means a phone number when the guard room device and the generation period call, and the path number is specified in the guard room device 1. The calculation of the checksum is performed by performing an exclusive OR from the first byte to the fourth byte (XOR; exclusive -OR), and then XORing the high and low nibbles of the one exclusive logical sum byte and XORing the nibble value with the path number. Calculate

Next, a data frame transmitted from the generation device 2 to the guard room device 1 will be described. The data frame also consists of 5 byte data, with the first byte always being set to 80H. The second byte stores data to be transmitted to the guard room 1. The third and fourth bytes are always set to 00H. The last fifth byte stores the high nibble path number and the low nibble stores the checksum. The calculation of the checksum is the same as the case of the data frame transmitted from the guard room device 1 to the generation device 2 described above.

For example, the functions of data stored and transmitted in the second byte of the data frame are shown in Table 1 below.

Table 1

Here, according to Table 1, a function-specific sequence (SEQUENCE) diagram when transmitting and receiving data frames between the guard room device 1 and the generation device 2 is shown in Table 2 below. Table 2 below is a flow chart performed when the power of the generation device (POWER ON).

TABLE 2

In Table 2, P_C represents a path number and a checksum. And * 1 is set to 55H or 0, the 55H represents a generation device with one channel (HI-101 old version 1.0), the case of 0 is a generation device with three channel (HI-101 V1.0) All models except).

And the generation device 2 does not respond to data other than the initial data (INITIAL DATA) of the guard room at power on in accordance with the present invention. That is, after receiving the initial data, it responds to other data.

In addition, if there is no response for a predetermined time (approximately 10 seconds) in the household device 2 after transmitting arbitrary data from the guard room device 1, the household device is considered to be down (DOWN) and the guard room device 1 transmits initial data. The generation device 2 must transmit ACK data upon initial data reception from the guard room device 1, and must transmit absence data.

Next, the flow chart at the time of occurrence of the situation in the generation device 2 is shown in Table 3.

TABLE 3

The SECU_DATA is data on a situation, for example, a fire 21H, a gas 22H, a method 23H, an emergency 24H, and the like.

Next, the operation flow for notifying the security device of the household device 2 when the household device ID is duplicated according to an embodiment of the present invention and generating an alarm sound by itself will be described in detail with reference to FIG. 2 and Table 1. FIG.

In the unmanned security system according to the present invention, once the household device 2 having an arbitrary ID receives initial data from the guard room device 1 and performs data communication, the other household device having the same ID as the ID is powered on. Also, the initial data cannot be received. Therefore, whether to duplicate the ID of the generation device 2 according to the present invention is determined with the reception of the initial data.

First, generation device 2 is powered on in step 211. The controller 21 of the generation device 2 checks whether data is received in step 213. In this case, if the data reception is checked, the controller 21 proceeds to step 215 to check whether the data is initial data (can be 71H, 72H, 73H, 74H, etc. of Table 1), and the data reception is checked. If not, the controller 21 proceeds to step 225.

If the initial data reception is checked in step 215, the controller 21 proceeds to step 231. If the initial data reception is not checked, the controller 21 proceeds to step 217. Has duplicate households'. On the other hand, the control unit 21 proceeds to step 231 and displays 'no ID overlapping generation' in the specific area of the memory 22.

In step 217 or step 231, the control unit 21 stores data related to ID duplication of the household device and proceeds to step 219. The control unit 21 checks whether ID duplication check data (28H of Table 1) is received from the guard room 1. In this case, when the reception of the ID duplication check data is checked, the controller 21 proceeds to step 221. If the reception of the ID duplication check data is not checked, the controller 21 proceeds to step 225.

The control unit 21 proceeds to step 221 and accesses a specific area of the memory 22 to check the data on whether or not ID overlap. If the ID duplication is checked, the controller 21 proceeds to step 223. If the ID duplication is not checked, the controller 21 proceeds to step 233.

The control unit 21 proceeds to step 223 and transmits 'no duplicate ID generation' data (29H in Table 1) to the guard room device 2, and the control unit 21 proceeds to step 233 'no duplicate ID generation' (28H in Table 1) is transmitted to the guard room apparatus 2.

In step 213, the reception of data from the guard room is not checked, or in step 219, the ID duplication check data is not received, or in step 223 or step 233, the data regarding whether or not the ID is duplicated is transmitted to the guard room device 2. The control unit 21 proceeds to step 225 checks whether the guard room call button is input. That is, it is checked whether the guard room call button 26 is pressed by the user.

At this time, if the guard room call button input is checked, the controller 21 proceeds to step 227. If the guard room call button input is not checked, the controller 21 terminates the program. In step 227, the controller 21 accesses a specific area of the memory and checks whether a generation device ID is duplicated.

In this case, if the ID duplication is checked, the control unit 21 proceeds to step 229, and if the ID duplication is not checked, the control unit 21 proceeds to step 235 to display 'guard room call data' (41H in Table 1). Send to

On the other hand, the ID duplication is checked and the control unit 21 proceeds to step 229 to control the alarm sound generating unit 23 to send a self alarm sound to the generation device 2 terminal and to recognize the generation device ID duplication time according to the present invention Quit the program.

As described above, according to the present invention, when the ID of the household device is duplicated in the unmanned security system of the bus system, the household device determines the overlap and notifies the guard room as well as sending out an alarm sound itself.
