JP3786045B2 - Control repeater for self-report receiver - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a control repeater connected to a self-report receiver by multiple transmission lines.
[0002]
[Prior art]
A conventional control relay for a self-report receiver uses a latching relay to reduce current consumption, and performs relay contact control output to a smoke prevention terminal by pulse output.
[0003]
[Problems to be solved by the invention]
However, since the conventional control repeater does not manage the output control signal information by itself, it cannot recognize the abnormal state even if it malfunctions due to noise or relay failure.
[0004]
The present invention has been proposed in view of such circumstances, and an object of the present invention is to provide a control relay for a self-report receiver capable of recognizing an output state with respect to a control terminal.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a control repeater for a self-report receiver according to claim 1 is connected to a fire receiver through a multiplex transmission line, and is controlled based on a control command received from the fire receiver. A control repeater configured to output control to the terminal, and outputs a control signal to the control terminal based on the control command, while generating an output confirmation signal based on the control command; And an information processing circuit unit for executing a predetermined terminal operation confirmation process based on the output confirmation signal . The control output circuit unit comprises a two-contact type relay, and the first contact point is connected to the control terminal. It is for output, and the second contact is used for output to the information processing circuit unit .
[0006]
Since the control repeater can recognize the output state for the control terminal, as a result, even if it malfunctions due to noise, relay failure, etc., it can recognize the abnormal state because it inputs the output confirmation signal itself, As a result, re-control output is possible for the control terminal.
[0007]
Here, the predetermined terminal operation confirmation process includes a terminal operation confirmation process performed in response to the output confirmation signal, a re-control process for the terminal, and the like.
[0008]
According to a second aspect of the present invention, the information processing circuit unit is configured to cause the control output circuit unit to again perform control output when there is no input confirmation signal despite the presence of a control command.
[0009]
According to a third aspect of the present invention, the information processing circuit unit is configured to cause the control output circuit unit to output a control stop when receiving an output confirmation signal when no control command is output.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0011]
FIG. 1 is a block diagram showing a main configuration of a control repeater for a self-report receiver according to the present invention.
[0012]
The control repeater 1 is connected to the fire receiver 3 via the multiplex transmission line L, and outputs a control to the smoke prevention terminal 2 or the transfer output equipment based on the control command from the fire receiver 3. Control output using a relay for controlling the fire transmitter 3 and the multiplex transmission circuit unit 1a for performing transmission control, the information processing circuit unit 1b composed of a CPU and the like, and the smoke prevention terminal 2 The circuit part 1c is provided at least.
[0013]
In the relay control output circuit unit 1c, a two-contact type relay is used. The first contact is output as a control signal for the smoke prevention terminal 2 (reference A in FIG. 1), and the second contact is output as an output confirmation signal for the information processing circuit unit 1b (reference B).
[0014]
When the control repeater 1 receives a control instruction from the fire receiver 3 via the multiplex transmission line L in the multiplex transmission circuit unit 1a, the control repeater 1 outputs a control command from the information processing circuit unit 1b to the relay control output circuit unit 1c. Then, in the relay control output circuit unit 1c, the control output is performed with respect to the smoke prevention terminal 2, and the operation of outputting the output confirmation signal to the information processing circuit unit 1b is executed.
[0015]
FIG. 2 shows a circuit diagram of a two-winding latching type relay that is an example of the relay control output circuit unit 1c. This figure shows a reset state.
[0016]
When a pulse drive voltage is applied to the set coil C2 side of the relay in the figure, the two contacts R1 and R2 are turned on, and the set state is maintained until an inversion (excitation of the reset coil C1) is input. That is, according to this relay, unless the relay is defective, a signal representing the same meaning is generated from the two contact points, one as a control signal for the smoke prevention terminal 2 and the other as an output confirmation signal for the information processing circuit unit 1b. As output.
[0017]
The output control may be either a voltage or no voltage.
[0018]
FIG. 3 is a flowchart showing a predetermined terminal operation confirmation processing operation of the information processing circuit unit 1b. The following description is divided into a case where there is a control command from the fire receiver 1 (steps 101 to 107) and a case where there is no control command (steps 101 and 108 to 110).
[0019]
(1) When a control command is issued, a pulse control output is output to the relay control output circuit unit 1c. After the timer, if an output confirmation signal is input, the process ends. If no output confirmation signal is input, the pulse control output is output again. Do. Then, this repulse control output process is repeated up to n times. If the input of the output confirmation signal can be confirmed, the process is terminated normally. If not confirmed, a failure signal is notified to the fire receiver 3 (step 101). ~ 107).
[0020]
That is, the control repeater 1 can recognize a control failure or the like of the relay or the like based on the presence / absence of the output confirmation signal. Further, since the control output is retried a plurality of times, it can be reliably re-controlled, and an abnormal signal can be reliably transmitted to the fire receiver 3 even when control cannot be performed.
[0021]
(2) If there is an output confirmation signal input from the relay control output circuit unit 1c when there is no control command, it is determined that there is a malfunction such as noise, and a stop (reset) control output is output to the relay control output circuit unit 1c. The fire receiver 3 is notified of a malfunctioning signal (steps 108 to 110).
[0022]
That is, since the control repeater 1 determines that the output confirmation signal input when there is no control command is abnormal, it is possible to quickly detect a malfunction due to noise or the like.
[0023]
The predetermined terminal operation confirmation process may include a notification process to an indicator lamp (not shown) based on the output confirmation signal.
[0024]
【The invention's effect】
As can be understood from the above explanation, the control repeater for the self-reporting receiver of claim 1 outputs an output confirmation signal from the control output circuit unit, so that it malfunctions due to noise or a relay failure. Even in this case, since the output confirmation signal is input by itself, the abnormal state can be recognized, and as a result, re-control output can be performed to the control terminal.
[0025]
According to the second aspect of the present invention, when the output confirmation signal is not input despite the control command, the control signal is output again. Therefore, the control signal can be reliably retransmitted to the control terminal. it can.
[0026]
According to the third aspect, when the output confirmation signal is received when there is no output of the control command, the control output circuit unit is configured to cause the control stop output to be output. Therefore, even when the control terminal malfunctions due to noise or the like, Can be stopped.
