Description

[Detailed Description of the Invention] Technical Field> The present invention comprises a plurality of transmitters that are placed in various places in a house and transmits abnormalities such as intrusion, fire, gas leakage, etc. detected by sensors, and This invention relates to a security device that includes a central controller that receives signals from a transmitter at one location and issues a predetermined alarm.

<Prior Art> In this type of security device, a house code is used to determine whether the signal is from a transmitter within the same house, and it is determined which transmitter within the same house the signal is from. For this reason, conventionally, transmitters use DIP switches for code setting or jumper wires for cutting, etc., but this increases cost and space, has structural limitations, or requires a unit code for transmitting when setting the code. There were drawbacks such as the need to open the container case.

<Objective> The object of the present invention is to obtain a security device that eliminates the above-mentioned drawbacks.

<Embodiment> An embodiment of the security device of the present invention will be described below with reference to FIGS. 1 to 4.

The transmitter of the security device of the present invention is constructed as shown in FIGS. 1 to 4, and in FIGS. 1 to 4,
1 is a case of the transmitter, 2 is a printed circuit board, 3 is a hole for inserting a code setting jig, 4 is a contact for code setting, and 5 is a conductive jig for code setting, which is used for inserting the above code setting jig. The number of holes 3 and code setting contacts 4 is twice as many as the number of code bits that need to be set, and by inserting the code setting conductive jig 5 into the code setting jig insertion hole 3. The code setting contact 4 is fired.

6 is a control unit; 7 is a control circuit in the control unit 6; 8 is a sensor that detects abnormalities such as intrusion, fire, gas leaks, etc.; 9 is a transmission unit that transmits various information signals to the central controller; 10 is a battery power source for operating the control section 6 and the transmission section 9.

The transmitter of the security device configured as described above is reset by the power-on reset circuit in the control circuit 7 when the battery power source 10 is turned on for the first time, and the code memory in the control circuit 7 stores rl, 1.1. The 4-bit binary code of IJ is set. Thereafter, by inserting the code setting conductive jig 5 into the code setting jig insertion hole 3 corresponding to the bit you want to change, the corresponding code setting contact 4 is shorted, and the control circuit 7 detects this and selects the bit. The bit in the code memory in the control circuit 7 is set to rQJ and held until the next battery replacement of the battery power source 10 is reset. The control circuit 7 also checks the presence or absence of an abnormality in the sensor 8, and when an abnormality is detected, outputs a signal obtained by adding the contents of the code memory to the abnormality signal to the transmitter 9, and the transmitter 9 accordingly emits weak radio waves. This causes the central controller to issue a predetermined alarm.

In the above case, changing the code memory in the control circuit 7 by shorting the code setting contact 4 may be possible at all times, or may only be possible for a certain period of time after reset. In addition, when the code setting is changed or a wrong setting is made, the code can be reset by removing and removing the battery 10 and performing a power-on reset, or by providing a short contact 4 and a hole 3 for resetting the code memory and replacing them. The contents of the memory for rl, 1, 1 . It can also be made into IJ. Furthermore, it is naturally possible to set the initial value to ro, o, o, OJ and set it to 1 by short-circuiting, or to increase the number of bits of the setting code.

Regarding the modification of the code memory in the control circuit 7, the configuration shown in FIGS. 5 and 6 may be used in addition to the above.

In FIG. 5, 11 is a transmitter, 12 is a connector connected from the outside of the transmitter 11 to transmit and receive signals, and 1
3 is a code setting fi for setting code data to be written and stored in the code memory of the transmitter 11 and sending it to the transmitter 11; 14 is connected to the connector 12 to input the code set by the code setting device 13; This is a connector for sending data to the transmitter 11.

When setting a code, connect the connector 12 of the transmitter 11 and the connector 14 of the code setting device 13, and
At step 3, set a code to be stored in the transmitter 11 using a switch or the like, and transmit it so that the transmitter 11 receives it and writes the code into the code memory, which is retained even after the connectors 12 and 14 are separated. .

FIG. 6 is a block diagram showing the internal configuration of FIG. 5. In FIG. After connecting the connector 14, a start switch 17 is used to start the code transfer.When the start switch 16 is input and the start switch 16 is turned on, the code set by the switch 15 is transferred to the I/F (interface) 18t. -T
.

This is a control unit that performs a series of controls for transmitting data to the transmitter 11.

When the battery of the transmitter 11 is first inserted, the power-on reset circuit in the control circuit 7 causes the code memory in the control circuit 7 to be stored, for example, rl, 1, 1, . The 4-bit binary code of IJ is set. After that, the connector 12 and the connector 14 are connected, and the switch 15 is set to, for example, rl, 0,
1. By setting OJ to ON and turning on the start switch 16, the control section 17 causes the switch 15 to output rl, 0, 1 . O
Send J-code.

The control circuit 7 stores the contents of the code memory as rl, 0, 1 . O
This is retained even after the connector 12 and connector 14 are separated.

Effects> Since the security device of the present invention has the above-described configuration, the code can be easily set from the outside without opening the case, and there is no need for parts such as switches for setting. This saves cost and space, making it possible to downsize the transmitter, and also increases the degree of freedom in design since there are many structural restrictions like switches.
