DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a housing information board system equipped with a plurality of sensors for sensing security information and daily life information, and a terminal device such as an intercom slave device for telephone calls.

[Background Art] Conventionally, there is a housing information board system of this type as shown in FIG.
Multiple various sensors 5IcI'i that detect security information such as leakage or crime prevention, and daily life information such as water leakage

It is equipped with a contact switch SW, such as a call switch, which is operated when making a call contact with a call VC station C such as a JII a device, and these sensors S and a contact switch SWo! ? Terminal B, and housing information board A that operates according to the output of terminal B. The housing information panel A includes a signal processing circuit that detects an abnormality detection output or an output signal such as a calling signal outputted from the terminal B and controls the operating state such as an alarm, a calling, or a telephone call, and the signal processing It includes an output circuit that operates an external device according to the circuit output, and an alarm circuit that issues an alarm based on the signal processing circuit output.

According to the output from the terminal device B, which is the sensor S, the housing information panel A emits an alarm sound from the speaker SP and displays a message on the display section.
When the terminal B, which is W0, is operated, the handset can be used to talk to a communication device C such as an intercom slave device.

The circuit configuration of this conventional housing information panel is shown in FIG. In this conventional example, in order to simplify the explanation, terminal devices B, ,
B2, and the priority of terminal B1 is higher than the priority of terminal B2. For example, terminal B1 has a higher priority than terminal B2.
, is a fire sensor S, and the terminal B2 is a communication switch SW0. These terminals B+ and B2 are connected between the input terminals T and T2 to the housing information board, and the input terminal T2 is grounded. The output of this terminal B1 is the transistor Q3
, a guiode D9, a capacitor C1, and a resistor.
The signal is input to an input section 7 consisting of a resistor. Here, the input units 6 and 7 are integrated. Since the terminal device B1 is a sensor S that detects an abnormal state, if this sensor S detects an abnormality, contact output etc.)! !
In other words, the input terminals T, , 72 are short-circuited, and a high level signal is output to the input section 6 output. This input part 6 output is transistor Q 3% light emitting diode LD, relay Rylkl? Output circuit 9 consisting of
is input, and the transistor Q becomes conductive, so that
The light emitting diode LD emits light to indicate an abnormality, and also drives the relay Ry to drive an external device using a relay contact (not shown). In the above explanation, two terminals B were used, but the configuration and operation of the output circuit 10 on the terminal B2 side are also substantially the same, so the explanation will be omitted. The output of the input section 6 on the terminal B1 side is provided with an alarm signal output circuit 11 which lacks the function of stopping the alarm. This alarm signal output circuit 11 includes alarm stop 1-switch SW,...) pulse generation circuit 12.7 lip 70
When the transistor Q of the output circuit 9 is on, the 7-rip 70γ circuit 13
When the output is at a low level, a /1 level signal indicating that an abnormality such as a fire has occurred in the terminal B1 is output. Then, by turning on the alarm sound stop switch SW1, the 7 lip 70 knob 13 output is set to high level,
The output of the NOR circuit 14 is set to low level and the alarm sound is stopped. The outputs of the alarm A and ¥ output circuit 11 are input to an output delay circuit 15, and are output after being delayed for a predetermined time. This output delay circuit 15 is composed of a transistor Q4, a comparison circuit 16, a capacitor C1, resistors R, R2, etc., and the delay time is determined by the time constant of the capacitor C0 and resistors R, R2. 6+ A^;

I! When the a11 output is at a high level, that is, when the terminal B1 detects an abnormality, the transistor Q becomes conductive, and the charge on the capacitor C3 in the charged state is transferred to the resistor R,...
Discharged via R2. Therefore, the input of the comparator circuit 16 decreases to below the reference voltage, and the output of the comparator circuit 16 becomes high level. This output delay circuit 1
The output 5 is input to the alarm output circuit 8', and the alarm sound generated by the W-noise generating circuit 17 is emitted from the speaker SP.

The above is the operation when an abnormality is detected on the terminal B side.

Next, when an output is generated on the terminal B2 side, for example, when the communication switch SWo is operated, a high level signal is generated at the input section 7 output, and this high level signal generates an alarm sound in the alarm output circuit 8. The circuit 17 generates an alarm, in this case a ringing tone, which is emitted from the speaker SP.

A case will be described in which the terminal B, .B2 output occurs simultaneously or the terminal B output occurs later. If there is no priority order, the alarm output circuit 8° outputs an alarm according to the output of the output delay circuit 15 or the output of the input section 7, whichever is output faster.
has priority. Therefore, the alarm output circuit 8' conducts the transistor Q5 when the output of the output delay circuit 15 occurs, so that the output from the terminal device 82 is not input to the alarm sound generation circuit 17. In other words, alarm output circuit 8°
are designed to operate according to priority order.

However, in the conventional circuit described above, since the signal processing circuit is constituted by a hard logic circuit, there are the following problems. That is,
In the above-mentioned circuit, the alarm signal output circuit 11, the output delay circuit 15, and the alarm output circuit 8'' that operate according to the priority order are required, which makes the circuit configuration complicated, and the delay time of the output delay circuit etc. Since the delay times are determined by , the time accuracy is poor, and furthermore, if it is desired to change these delay times, it may not be possible due to the space on the printed circuit board, etc., resulting in a problem that the system lacks flexibility. Moreover, after outputting the ring tone to the intercom thumb,
When the telephone line is switched to the interphone sub-main unit, there is also a problem in that the ringing tone is output from the interphone sub-main unit due to the retention effect of the capacitor component of the interphone baby finger.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and its purpose is to simplify the circuit NIT precept, improve the time accuracy of the delay time, and increase the flexibility of the system. The purpose of the present invention is to provide a housing information board system that can improve the quality of housing.

[Disclosure of the Invention 1 (Embodiment) Figures 1 to 3 show an embodiment of the present invention. In this embodiment, the signal processing circuit 1 of the conventional housing information panel A described above is implemented by a microcomputer. This is done using software. In addition, input sections 6, 7, output circuits 9, 1
0 and the alarm output circuit 8 are similar to conventional circuits except that the alarm output circuit 8 does not include priority setting means.

In addition, in the following explanation, terminal B, which is similar to the conventional example,
The case where two B2 are used will be explained, and this terminal B1
is a sensor S that detects fire, etc., and the terminal B2 is a communication switch SW0. More specifically, as shown in FIG. A reading determination means 3 reads the output and determines whether the read terminal B, B2 output is abnormal or in a calling state, and when the reading determination means 3 detects an abnormality etc., the terminal B ,, an output controller 4 that operates the output circuits 9 + 10 according to the output of B2, and a delay means 5 that drives the alarm output circuit 8 with a predetermined time delay after the output of the output control means 4 is generated. This constitutes a signal processing circuit 1.

The operation will be explained below according to chart 70 in FIG. First, the reading determination unit 823 reads the outputs of the terminals B 1 and B 2 via the input units 6 and 7 according to the priority set in the priority setting means 2 .

In this embodiment, since terminal B1 has a higher priority, the output of terminal B1 is read first. The reading determination means 3 then determines from the read outputs of the input units 6 and 7 whether or not the terminal B has detected a small output abnormality. If there is an abnormality, a high level signal is input to the input of the output circuit 9. Therefore, the transistor Q of the output circuit 9 becomes conductive, causing the light emitting diode LD to emit light and driving the relay RF+. At the same time that the above judgment output is generated, the timer of the delay means 5 is set, and a time-limiting operation for a predetermined period of time is started.

Then, an alarm signal is manually inputted to one input of the alarm output circuit 8 at the timer output when a predetermined time has elapsed. In response to this alarm signal, an alarm sound signal is output from the alarm sound generation circuit 17 of the alarm output circuit 8, and an alarm sound is emitted from the speaker SP. The 'qJ alarm continues to sound until the alarm stop switch SW is turned on or the terminal B is reset.

The above is a description of the case where the output from terminal B is occurring. Next, the case where there is no output from terminal B will be described. First, in the same way as described above, terminal B, which has the highest priority, is read and it is determined whether there is an abnormality, but since terminal B does not have a small output, the output of terminal B2 is input next. The information is read by the reading determination means 3 via the section 7, and it is determined whether the contact switch SW0 is operated or not and whether there is a call. If it is not called, the program returns to the initial state and the program is executed from the beginning. Conversely, if there is a call, then a new terminal B+
The output is read, and if there is an output from the terminal device B1 at this time, the light emitting diode L D emits light to provide a display, as in the case where there is the terminal device B1 output described above, and the relay R is activated.

1 to emit an alarm after a predetermined time delay.

In addition, when the terminal B does not have a small output, a high level signal is output to the output circuit 10 and the alarm output circuit 8 for the first time, transistor Q2 of the output circuit 10 is made conductive, relay Ry2 is driven, and an alarm sound of the alarm output circuit 8 is generated. A ringing tone signal is output from the circuit 15, and the ringing tone is emitted from the ST and -tSP.

When this ringing tone is emitted, the ringing tone is stopped by a ringing tone stop signal when the handset of the called device is picked up. In this way, according to this embodiment, the δ processing circuit 1 can be configured by a microcomputer, which simplifies the circuit configuration, and by using the timer of the microcomputer, the delay time etc. The time accuracy is improved, and since a CR circuit is not used to set the delay time as in the conventional method, the delay time can be easily changed, and the versatility of the system is improved. Moreover, in the conventional circuit, when the call line is switched to the interphone secondary unit after the ring tone is output to the intercom thumb, the above circuit does not take any measures, so the capacitor component of the intercom thumb is There has been a problem in that the ringing tone is output from the intercom sub-base unit due to the holding effect, but according to this embodiment, the above-mentioned problem can be solved by software delay.

In addition, in the above description, the case where the terminal devices B, B2 are the sensor S and the communication switch SWo is explained, but the terminal device B1182
Both may be of different types of sensors S, and even if there are a large number of sensors, the same operation can be performed based on the above-mentioned operation.

[Effects of the Invention] As described above, the present invention includes a priority setting means for setting priorities for each terminal, and a method for sequentially reading the output of each terminal according to the priority setting means and outputting the read terminal. reading determination means for determining whether the reading determination means is in an abnormal state, etc.; output control means for operating the output circuit in accordance with the terminal output when the reading determination means determines that the abnormal state, etc. is present; Since the signal processing circuit is constituted by the delay means for driving the alarm circuit with a predetermined time delay after the output of the control means is generated, the operation of the signal processing circuit can be processed by software of a microcomputer. Furthermore, since the delay means can be configured by counting time with a microcomputer, the delay time can be easily changed without using a CR circuit, increasing the versatility of the system. Moreover, when the conventional circuit outputs the ring tone to the intercom little finger and then switches the call line to the interphone sub-base, the capacitor component of the interphone little finger, for which no measures were taken in the circuit described above, There have been cases where the ringing tone is output from the intercom sub-base unit due to the holding action of , but the software delay caused by executing each of the above means has the effect of preventing the ringing tone from being outputted.
