2. Description of the Related Art In recent years, devices that can be operated from a remote place by a remote controller have been increasing. For example, in a car security device for preventing theft or mischief of an automobile, a security device main body is attached to a vehicle, and a user turns on or off a security function from outside the vehicle using a remote controller.

In the above-described car security device, an ID code for distinguishing each remote controller from other remote controllers is set, and a signal output from the remote controller includes an ID unique to each remote controller. The code has been added. The security device body ignores the received signal when the ID code added to the received signal does not match the ID code registered in the device in advance. This ensures security.

However, in a conventional remote control device in which an ID code is set for each device like the above-mentioned car security device, the ID code is written in a remote controller or a device main body for maintenance of the device. There is a drawback that when it is necessary to check the ID code, reading the ID code is extremely complicated. That is, conventionally, to read the ID code, for example,
Fuse ROM with read code (Read Only
Memory) or EEPROM (Electrically Erasable Pr)
It is necessary to attach a dedicated jig to an IC (integrated circuit) such as an ogramable ROM, read the ID code directly as binary data using an oscilloscope or a logic analyzer, and analyze the read data.

Accordingly, an object of the present invention is to provide a remote control device capable of reading out an ID code written in a remote controller or a device body by a simple operation.

Or The security device main body 10 is connected to an on-vehicle power supply 31, an ignition switch 32, a valet switch (Valet) 33, and a door lock unit 34. Then, the security device body 10 can detect the states of the ignition switch 32 and the valley switch 33. The valley switch 33 is installed in an inconspicuous place such as below the dashboard, and is used when the security function is released without the remote controller 11.
Further, the door lock unit 34 is connected to the remote controller 11.
For locking and unlocking the door in response to a signal from

Hereinafter, an alarm device and a sensor connected to the security device main body 10 will be described. The starter cut relay 21 is for preventing the engine starter from rotating when the security device body 10 detects an abnormality. The siren drive unit 22 sounds a siren when the control unit 17 detects an abnormality, and notifies the surroundings of the occurrence of the abnormality.

[0015] In this car security device, after the user removes the ignition key and gets off the vehicle,
When the security function on button of the remote controller 11 is pressed, the security device main body 10 starts monitoring the state of each sensor. If an abnormality is detected, the security device main unit 10 drives the siren driving unit 22 or the headlight driving unit 23 to generate an abnormality. To the surroundings, and the memory unit 1 uses the sensor detecting the abnormality and the time when the abnormality is detected as security information.
4 is stored. At this time, the control unit 17 acquires the time when the abnormality is detected from the clock unit 15. Thereafter, by a predetermined operation of the user, the security device main body 10 transmits the security information stored in the memory unit 14 to another device including a liquid crystal display device or the like via the bus input / output unit 16, or 12 to the remote controller 11, the liquid crystal display device of another device or the display unit 11 of the remote controller 11.

Hereinafter, the operation of the car security device of the present embodiment at the time of reading the ID code will be described. (1) Reading the ID code of the remote controller When reading the ID code written in the memory unit 44 of the remote controller 11, the remote controller 11
Battery 46 is once removed and then reattached. Then, the control unit 41 enters a reset state, executes an initial program, initializes the device, reads the ID code stored in the memory unit 44, and reads the ID code from the display unit 11.
Let a be displayed in hexadecimal.

For example, when two predetermined buttons of the operation unit 43 are simultaneously pressed for two seconds or more, the control unit 41 reads out the ID code from the memory unit 44 and displays the ID code on the display unit 11a. It may be. Thus, the ID code set in the remote controller can be easily confirmed without using an oscilloscope or a digital analyzer.

(2) Reading the ID code of the security device main body When confirming the ID code stored in the memory section 14 of the security device main body 10, the security device main body 1
0 is once disconnected from the power supply 31 and then connected again. Then, the control unit 17 enters a reset state, executes the initialization program to initialize the device, and then reads the ID code written in the memory unit 14. Then, the ID code is transmitted to the remote controller 11 via the transmission / reception unit 12.

The control unit 41 of the remote controller 11
When the ID code is received from the security device main body 10 via the transmission / reception unit 42, the ID code is displayed on the display unit 1.
1a is displayed in hexadecimal. For example, when two predetermined buttons of the operation unit 43 of the remote controller 11 are simultaneously pressed, the remote controller 11 outputs an ID request signal. The code is read out and output to the remote controller 11 via the transmission / reception unit 12, and the control unit 4 of the remote controller 11
1 receives the ID code via the transmitting / receiving unit 42,
This ID code may be displayed in hexadecimal on the display unit 11a.

In this way, the ID code registered in the security device main body can be easily confirmed.
In some cases, one vehicle to which the car security unit 10 is attached is used by a plurality of users. In this case, each user owns the remote controller 11. Since different ID codes are registered in the respective remote controllers 11, the ID codes of the plurality of remote controllers 11 are registered in the security device body 10.

As described above, when a plurality of ID codes are registered in the security device main body 10, the control unit 17 reads out the ID codes in order and transmits them every few seconds. Then, the remote controller 11 switches and displays a plurality of ID codes registered in the security device body 10 every few seconds. Further, in the remote controller 10, a plurality of ID codes received from the security device main body 10 may be stored in the memory, and may be scroll-displayed on the display unit 11a.

In the above-described embodiment, the case where the ID code written in the remote controller of the car security device and the main body of the device is read has been described. However, it is needless to say that the present invention is not limited to the car security device. In addition, the present invention can be applied to other remote control devices in which an ID code is set for each remote controller.

[0023]

As described above, according to the first aspect of the present invention, since the control unit for reading out the ID code written in the ID code storage unit of the remote controller and displaying it on the display unit is provided, special treatment is performed. The ID code set in the remote controller can be easily confirmed without using a tool, an oscilloscope, or a device such as a digital analyzer.

According to the second aspect of the present invention, the control section of the device main body reads out the ID code written in the ID code storage section and transmits this ID code via the transmission / reception section on the device main body side. Since the control unit displays the received ID code on the display unit, it is possible to easily check the ID code registered in the device body without using a special jig, oscilloscope or digital analyzer. it can.
