However, in the former case described above, all the ID codes are deleted even if only one of the many registered ID codes is desired to be deleted. However, the flexibility is poor, and after all the ID codes have been deleted, it is necessary to re-register the necessary security transmitter ID code again. Therefore, it is troublesome and very inconvenient. On the other hand, in the latter one of the above-mentioned conventional ones, since a dedicated wireless transmitter for erasing the ID code is required, the cost of the wireless transmitter is high, and moreover, the cancel operation using the wireless transmitter results in wireless operation. It was also inconvenient because it was not easy to confirm whether or not the predetermined ID code was deleted from the receiver.

The present invention has been proposed in view of the above points, and the ID code of a desired security transmitter can be accurately and efficiently obtained by a simple operation from a plurality of ID codes registered in the wireless receiver. The purpose is to be able to delete each individual well.

Is. Then, when the ID code is registered, the received signal is transmitted to the control data discriminating means 6 side, but when it is not registered, no positive signal processing is performed and the wireless signal is not accepted. It will be similar.

The control data discriminating means 6 decodes the control signal transmitted from the ID code coincidence discriminating means 5, and, for example, when the signal is data indicating that a fire has occurred, an alarm alarm sounds. , Indicator lamp blinks,
Alternatively, a predetermined notifying unit (not shown) is operated so as to perform a warning operation such as displaying a message on the display unit 2.

As shown in FIG. 2, the key operating portion 1 is constructed by providing various switches on the operating panel 8 of the housing case 7. The key operating portion 1 includes the wireless receiver A of the wireless receiver A. A mode selection switch 1a for selectively setting the operation mode, a registration screen display feed switch 1b,
The transmitter selection switch 1c, the clear switch 1d, and other switches are provided.

Of these switches, the mode changeover switch 1a is used to change the normal security information monitoring mode of the wireless receiver A to the ID code registration / deletion mode. Upon operation, the wireless receiver A is first configured to shift to the ID code screen display registration mode. In this screen display registration mode, FIG.
As shown in FIG. 4, the ID code registration mode, that is, the security transmitter registration mode is displayed in characters on the display unit 2, and at this point the security transmitter B1
When the wireless receiving unit 4 receives the wireless signal to which the ID code is added from Bn to Bn, the data of the ID code added to the signal is decoded and the data of the ID code is stored in the system data table 3. , Is configured to register.

However, in this screen display registration mode, the ID
Not only the code can be registered, but the registered I
It also has the function of erasing D-code data. That is, for example, if the ID code received from the security transmitter B1 scheduled to be unused is registered due to an error, if the clear code 1d is operated within the predetermined time,
The registration of the ID code can be immediately deleted. Further, by repeating the operation of the clear switch 1d, the previously registered ID codes can be sequentially read and erased while being displayed on the display unit 2.

The registration screen display feed switch 1b is a switch for shifting from the screen display registration mode to the screen display registration deletion mode, and by operating this switch,
The wireless receiver A is configured such that its mode is switched and, at the same time, that fact is displayed on the display unit 2 as shown in FIG. At that time, the display unit 2
Is configured to display the name and number of the security transmitter to be deleted. The transmitter selection switch 1c is an operation switch for sequentially screen-switching the sensor name of the security transmitter displayed on the display unit 2 and its number in the screen display registration deletion mode.
The clear switch 1d is a switch that is used not only for deleting the error ID code at the time of registration of the above-mentioned ID code but also for general operation when deleting the registration of the ID code stored in the system data table 3. The ID code corresponding to the security transmitter displayed on the display unit 2 is deleted when operated in the screen display registration deletion mode.

The wireless receiver A according to this embodiment has the above configuration, and its operation will be described below. First, in use, the ID codes of the security transmitters B1 to Bn to be used are registered in the wireless receiver A in advance. This registration work is performed by the mode changeover switch 1
After the wireless receiver A is set to the screen display registration mode by operating a, the security transmitters B1 to Bn
It is only necessary to output a wireless signal (security signal) including the D code. The data of the ID code included in such a radio signal is received by the wireless reception unit 4 and the content of the data is decoded, so that the data is sequentially stored and registered in the system data table 3. In addition, in the registration mode, the delete mode function can be exerted within a predetermined time after the registration mode is set. Therefore, if an unnecessary ID code of the security transmitter is registered by mistake,
By operating the clear switch 1d, the wrong ID
You can immediately deregister your code. Steps 100 to 109 of the flowchart of FIG. 4 show an operation procedure at the time of the above series of ID code registration.

When the ID code registration work is completed as described above, thereafter, the wireless receiver A is provided with an ID code wirelessly output from each of the security transmitters B1 to Bn in the normal security information monitoring mode. When the security signal is received, only the security signal to which the ID code registered in advance in the system data table 3 is added is accepted, and the processing according to the content of the control signal included in the security signal is performed.

Therefore, it may be desired to individually cancel the use of any one of the security transmitters B1 to Bn whose ID codes have been registered in advance. In such a case, first, the mode changeover switch 1a and the registration screen display feed switch 1b are successively operated to set the wireless receiver A to the screen display registration deletion mode shown in FIG. 3B. .. Then, the transmitter selection switch 1c is operated to scroll the screen cover to display the sensor name of the security transmitter whose use is to be stopped, its number, etc. on the screen, and then operate the clear switch 1d. By such an operation, the registration of the ID code corresponding to the sensor transmitter displayed on the screen of the display unit 2 is individually deleted from the system data table 3. That is, for example, if the clear switch 1d is operated in the screen display state of FIG. 3C, the ID code corresponding to the security sensor 2 is individually erased. Steps 200 to 208 of the flowchart of FIG. 5 show the operation procedure at the time of the work for deleting the registration of the series of ID codes.

In the above embodiment, the case where the ID code added to the radio signals output from the security transmitters B1 to Bn is used to register the ID code has been described, but the wireless reception according to the present invention is described. In the container, as another method, the ID code may be input and registered by operating the ten-key pad 1f shown in FIG. 2, for example. Further, in the present invention, the deletion of the ID code registration is individually performed, but as another function,
For example, all registrations of the ID code may be deleted at once.

[0024]

As can be understood from the above description, according to the wireless receiver of the present invention as defined in claims 1 to 3, a desired security transmission is made from a plurality of ID codes registered in the wireless receiver. When erasing the ID code of a device, it is convenient that only the ID code to be deleted can be deleted individually by a simple operation and without any special transmitter, etc. Since the operation can be performed after the name of the security transmitter is displayed on the screen and confirmed, it is possible to appropriately prevent the necessary ID code registration from being deleted by mistake.

In particular, according to the invention of claim 2, I
Even when registering the D code, the name of the security transmitter corresponding to the ID code to be registered can be displayed on the screen, so that the ID code data input is highly accurate and more convenient. Is.

Further, according to the invention of claim 3, I
If you make a mistake when registering the D code, you do not need to change the operation mode of the wireless receiver from registration mode to deletion mode one by one, and you can simply operate the clear switch. Since the registration can be immediately deregistered, there is a merit that the registration of the ID code and the operation of the deregistration become easier.
