The alarm signal processing circuit can be applied to various technical fields, and it can be widely used for theft detection system, danger detection system, abnormality detection device of factory control system, power supply of large equipment such as ship, water level and other abnormality detection device such as valve. have.

Each of these alarm signal processing circuits has a problem in the overall monitoring system because it is possible to know whether the corresponding part is abnormal when an error occurs individually.

Therefore, in order to process such an alarm system comprehensively, a plurality of inputs which process a signal input in a system by detecting a signal displayed through a monitor using a monitor display system may cause an abnormal signal to a central control unit. When the system detects a failure, the central processing unit (CPU) is configured to control the output of all alarms so that the system can be checked.

However, in such a conventional system, all abnormality signals inputted to the device are processed centrally, and all control of the alarm unit for generating an external alarm is performed from this, so that an abnormality in the function of the internal CPU (CPU) or alarm circuit is prevented. If it occurs, the other alarm circuit is also unable to operate normally, there was a problem that the entire alarm system is paralyzed.

In addition, such a system requires considerable technology and cost in its installation, and operation is expensive because the reading and manipulation of the displayed data requires specialized knowledge.

On the other hand, it is difficult to expand the performance of the equipment because the existing systems usually use analog methods, and there are many limitations in scalability due to many limitations in constructing a collective alarm system that detects anomalies in many places. .

The present invention is to solve such a problem,

SUMMARY OF THE INVENTION An object of the present invention is to provide a collective alarm transmission apparatus capable of processing each alarm signal circuit independently and simultaneously processing the alarm signal.

Another object is to provide a collective alarm transmission device that is easy to apply to existing systems and excellent in scalability and suitable for monitoring a large number of systems.

Still another object is to provide an integrated alarm transmission device that is easy to manage while operating without affecting other alarm devices when the input side and output side are electrically insulated from each other.

In order to achieve the above object, the present invention is commonly connected to a plurality of alarm means for outputting a digitized signal from the input of the abnormal signal (ABNORMAL SIGNAL) to the alarm output, and the output terminal of the plurality of alarm means Common control means for synchronizing the output of the flashing signal of each alarm circuit and sensing a plurality of inputs of abnormal occurrence signals, and common control of the plurality of alarm means to release the alarm and return to the normal state. And by means of releasing means for releasing the aggregated signal.

The plurality of alarm means comprises a separate processing unit for each alarm circuit to which the error occurrence signal is input so that the alarm output function can be independently performed by an error occurrence signal input unit (alarm circuit) to which a signal is introduced without central control. The common control unit is configured as a common processing unit to synchronize and control the flashing output of each alarm circuit, and to configure a terminal for outputting a separate buzzer and a second alarm signal.

In addition, when canceling the alarm and returning to the normal state, the collective signal releasing means must drive the buzzer stop switch, stop the flashing with the lamp flashing switch, and then reset the individual processing devices of each alarming means with the reset switch in common. It characterized in that the release.

The plurality of alarm means and the collective signal releasing means provide insulation through the use of photocouplers between the individual and common processing devices (CPU-1, CPU1, CPU2, CPUn) and abnormal occurrence signals and operation signals from the outside. This prevents malfunction and damage of individual and common processing units (CPU-1, CPU1, CPU2, CPUn) due to abnormal voltage and current.

In this case, the independence of the alarm circuits is ensured so that the alarm operation of other circuits does not occur even if damage is caused to one circuit.At the same time, a common control unit having a separate common processing unit can be configured to generate an extended alarm. At this time, the alarm circuits with the abnormal signal input are configured to generate a synchronized alarm.

In addition, the above operation is digitalized by using each individual processing unit (CPU1, CPU2, ... CPUn) for each alarm circuit, which enables more stable operation than the conventional configuration, and the operation of the individual processing unit is also introduced through the contact point. Insulation between the abnormal signal input unit and the individual processing unit is prevented from malfunctioning and damage by the surrounding environment so as not to be affected by the voltage current of the abnormal signal. It will be described in detail as follows.

1 is a block diagram illustrating an apparatus for transmitting a set alarm signal according to the present invention.

Each of the first alarm circuit 1, the second alarm circuit 2, and the n-th alarm circuit n is driven by receiving an abnormal occurrence signal of the control circuit in the system of the previous stage. That is, when an error occurrence signal is applied, the first alarm circuit (1), the second alarm circuit (2), and the n-th alarm circuit (n) corresponding to the corresponding part are driven independently to inform the abnormal condition. .

In addition, the common outputs of the first alarm circuit 1, the second alarm circuit 2, and the n-th alarm circuit n are connected so as to be input into the common control circuit 10 on one side, and this common control circuit 10 ) Is commonly connected to a separate processing unit (CPU-1) to monitor the overall abnormality of the system (ST1).

On the other side of the common outputs of the first alarm circuit 1, the second alarm circuit 2, and the n-th alarm circuit n, an aggregate signal canceling unit 5 is formed so that the buzzer, a flashing signal, and a reset signal are generated. It is configured to control common.

In addition, the present invention is easy to expand, and when a plurality of systems (ST2) and (STn) are used, the second alarm signals 19 are output from the common processing unit in each common control circuit so that the upper individual alarm circuits ( 1-1, 2-1, n-1), and this signal is applied to the common control circuit 10-10, and when released, the signal is released by the upper group signal release unit 5-10. In the case of using a large number of systems, the above output is sent to facilitate expansion.

2 shows an exemplary circuit diagram of the collective alarm signal transmitting apparatus of the present invention.

The first alarm circuit 1 is composed of a photo coupler PC1 and an individual processor CPU1 for receiving and recognizing the photocoupler signal, and an alarm display lamp LP1 is connected to the individual processor CPU1. Each has an external relay drive output (SSR1) and an external lamp output (LAMP1).

The remaining second alarm circuit 2 and the n-th alarm circuit n have the same structure as the first alarm circuit 1.

The sensor parts 11, 12, and 13 connected to the front end of the first alarm circuit 1, the second alarm circuit 2, and the n-th alarm circuit n also have the same structure. . For example, the sensor unit 11 supplies an abnormal signal to the first alarm circuit 1 at the rear end, which may be configured slightly differently depending on the object (system) to be monitored.

For example, it is possible to detect power status, hydraulic status, water level, valve, etc. in case of using for various alarm system of ship. When contact signal is used, it is abnormal at normal contact point ("A" or "B"). A contact ("B" or "A") is switched to, and the photo coupler PC1 of the first alarm circuit 1 is connected to this contact to detect an abnormality.

In addition, even when applied to a system that detects fire, theft, etc., when the relay contact is used, when the relay is switched from the normal contact ("A" or "B") to the abnormal contact ("B" or "A"), the relay It is configured to be connected to the contact to check the abnormality.

If an electronic sensor is used instead of a relay for monitoring other electronic control devices, the photocoupler (PC1) is directly connected to the output of the electronic sensor to detect an abnormality.

The output terminals of the first alarm circuit 1, the second alarm circuit 2, and the n-th alarm circuit n commonly use the output side buses of the respective processing units CPU1, CPU2 and CPUn. One side is connected to the common control circuit 10, and the other side is connected to the collective signal releasing unit 5.

The common control circuit 10 includes a common processing unit CPU-1, and receives the signals of the first alarm circuit 1, the second alarm circuit 2, and the n-th alarm circuit n to determine whether there is an abnormality. The output terminal is connected to a power lamp 16, a monitoring flashing display lamp 17, and a buzzer output terminal 18, and a buzzer (not shown) is connected through the buzzer output terminal 18. .

In addition, the second alarm signal output terminal 19 as an output terminal of the common processing unit (CPU-1) is configured to send an alarm signal to a higher set alarm signal transmission device when a plurality of alarm devices are used. (See FIG. 1).

The collective signal release unit 15 is connected to each of the buzzer stop switch S1, the flashing stop switch S2, and the reset switch S3 through the respective photo couplers PC11, PC12, and PC13. It is.

In the present invention configured as described above, a case in which the present invention is applied to, for example, a ship system will be described. In FIG. 2, a front end of the first alarm circuit 1, the second alarm circuit 2, and the n-th alarm circuit n is described. It is connected to the contact terminal (A or B contact) of the sensor parts 11, 12, and 13. The contact terminal (A or B contact) has a photocoupler (PC1) of the alarm circuit (1) connected to the contact terminal (A or B contact) connected by a contact signal when there is an abnormality in power supply, oil pressure, water level, valve, etc. Is connected. If the abnormality is detected as a digital signal, the output of the sensor is directly applied to the photocoupler PC1.

The output of the photocoupler PC1 is applied to the individual processing unit CPU1 so that when an abnormal signal is input, the individual processing unit CPU1 of the first alarm circuit 1 blinks its own alarm lamp LP1 and at the same time the external output terminal. External relay drive output can be sent to (SSR1), and external lamp output can be sent to external output terminal (LAMP1).

This function can be used by applying a relay to the external output terminal (SSR1) when an external speaker or phone is required as an option, and can be connected to the external output terminal (LAMP1) when a separate lamp is required.

The remaining second alarm circuit (2) and the n-th alarm circuit (n) can perform the same function as the first alarm circuit (1). When detecting whether or not the second alarm circuit (2) can be detected whether the hydraulic abnormality, the n-th alarm circuit (n) can detect whether or not the abnormality of the valve. In addition, the first alarm circuit (1), the second alarm circuit (2), and the n-th alarm circuit (n) each have a separate configuration and a separate individual processing unit, and are not affected even when another alarm circuit is broken. There is an effect that can detect abnormality independently.

In addition, the outputs of the first alarm circuit 1, the second alarm circuit 2, and the n-th alarm circuit n are commonly applied to the common control circuit 10 so that the common processor of the common control circuit 10 ( CPU-1) is applied to the user to recognize whether or not an abnormal signal is input as a whole.

That is, the buses between the individual information processing units CPU1, CPU2, ... CPUn and the common processing unit CPU-1 in FIG. 2 are classified into two types according to the signal transmission direction, and among them, the individual information processing unit. Through the signal transmission line (data bus) corresponding to the output from (CPU1, CPU2, ... CPUn) to the common processing unit (CPU-1), the above first alarm circuit (1) and second alarm circuit (2) Even if an error occurrence signal is inputted in any one of the nth alarm circuits (n), it is applied through the common processing unit (CPU-1) of the common control circuit 10, so it is recognized and alarmed to the buzzer output terminal 18. The sound is intermittently generated and at the same time, the lamp connected to the blinking display terminal 17 blinks to indicate that an abnormal alarm signal is generated.

At this time, the common control unit CPU-1 immediately detects an abnormality through the pulse signal from the individual information processing units CPU1, CPU2, ... CPUn and another common information processing unit (CPU1, CPU2, ... CPUn) and the common processing unit. The first alarm circuit (1) and the second alarm circuit (1) by continuously sending pulse signals to the individual information processing units (CPU1, CPU2, ... CPUn) through different signal transmission lines (data buses) between (CPU-1). 2), the flashing display lamps LP1, LP2, LPn of the n-th alarm circuit n, and corresponding circuits of the external lamps LAMP1, LAMP2, and LAMPn into which the abnormal signal flows. The output of the lamps flashes in synchronization with these pulse signals, and accordingly, the monitoring flashing lamp 17 also flashes in synchronization. Here, the power lamp 16 connected to the power display terminal checks whether the common processing unit (CPU-1) is operating normally. Indicates whether or not.

Therefore, when an error occurs in the system to be monitored, the user checks whether an error has occurred in the current system by the alarm sound output through the buzzer output terminal 18 of the common monitoring circuit 10, and the detailed location is described in the first section. Flashing of the alarm display lamps LP1 and LAMP1, LP2 and LAMP2, LPn and LAMPn of the alarm circuit 1, the second alarm circuit 2, and the nth alarm circuit n You can check whether or not.

Here, the first alarm circuit (1), the second alarm circuit (2), the n-th alarm circuit (n) and the common monitoring circuit 10 are configured in one monitoring system circuit, the first alarm circuit (1) ), The second alarm circuit (2) and the n-th alarm circuit (n) are composed of cards, which can be expanded whenever the number of monitoring points increases. It detects whether or not, and the flashing of the lamp, which is the sensing means, and the buzzer are mounted on the outside, so that the monitoring can be performed at a place where the monitoring is easy.

In addition, the common processor CPU-1 of the common control circuit 10 has a separate second alarm signal output terminal 19 so that the circuit of FIG. By doing the same, it is possible to send output to the upper alarm circuit, so that it is easy to expand.

When such an abnormal point is found and the alarm is to be canceled, the collective signal canceling circuit 5 controls the entire system. That is, the collective signal canceling section 5 and the individual alarm processing sections CPU1, CPU2, .. The bus between the CPUn and the common processor CPU-1 is composed of three signal transmission lines. The first is a buzzer stop switch S1 and the individual alarm processor CPU1, CPU2, CPUn. ), A signal transmission line is formed between the common processing unit (CPU-1), and the second is between the flashing stop switch (S2) and the individual alarm processing units (CPU1, CPU2, ... CPUn) and the common processing unit (CPU-1). In the third, a signal transmission line is formed between the reset switch S3 and the individual alarm processing units CPU1, CPU2, ... CPUn. In order to cut off the alarm sound, press the buzzer stop switch S1 and the low level signal is connected through the line. U-1) and each of the individual alarm processing units (CPU1, CPU2, ... CPUn), so that the buzzer output is stopped in the common processing unit (CPU-1), and the individual alarm processing units (CPU1, CPU2, ... CPUn) This state is memorized. If the flashing stop switch (S2) is pressed after stopping the buzzer, the low level (LOW) signal is transmitted to the common processing unit (CPU-1) and each individual alarm processing unit (CPU1, CPU2, ... CPUn) connected through the line. The individual alarm processing units (CPU1, CPU2, ... CPUn) store this and the common processing unit (CPU-1) stops outputting the pulse signal for synchronizing blinking, so that the monitoring lamp 17 and the alarm display lamp ( The abnormality signal of LP1 (LP2) (LP3) and external lamps (LAMP1) (LAMP2) (LAMPn) is input and flashes in synchronization with the monitoring display lamp 17 as described above. The corresponding lamp among LP2) (LP3) and the corresponding lamp among the external lamps (LAMP1) (LAMP2) (LAMPn) will stop flashing.Press the flashing stop switch (S2) to Check if any abnormality has occurred by recognizing the relevant lamp among the alarm display lamps LP1, LP2, and LPn that stops blinking and stays lit afterwards, and the corresponding lamp among the external lamps (LAMP1), LAMP2, and LAMPn. Then, the reset switch S3 is pressed to separate the processing units CPU1, CPU2, CPUn in the first alarm circuit 1, the second alarm circuit 2, and the nth alarm circuit n. They will be reset in common, but the external relay output (SSR1) will continue unless an error is cleared at the contact point (A or B contact) of the sensor section (11), (12) or (13) in advance. It is configured in the individual alarm processing units (CPU1, CPU2, CPUn) to generate SSR2, SSRn) and external ramp outputs (LAMP1, LAMP2, LAMPn) to visually instruct the administrator to fully recover the alarm system. , The signal from the buzzer stop switch (S1) and the signal from the flashing stop switch (S2) Since it is stored in the individual alarm processing units (CPU1, CPU2, ... CPUn), when there is no signal from the flashing stop switch (S2), even if a signal is input from the reset switch (S3), the individual alarm processing units (CPU1, CPU2, ... CPUn is not released and even if a signal is input from the reset switch S3 after a signal is input from the flashing stop switch S2, the individual alarm processing units CPU1, CPU2, ..
