Hereinafter, a facility integration control device according to the present invention will be described in detail with reference to the drawings.

1 is a structural diagram showing the structure of a facility integrated control apparatus according to the present invention.

1, the equipment integration control apparatus 100 includes a receiving unit 110, a comparison unit 120, a switch unit 130, a voltage follower 140, a non-inverting buffer 140, a distribution unit 150 A control unit 160, an output unit 180, and a signal output unit 170.

The receiving unit 110 can receive equipment signals transmitted by external equipment. The receiving unit 110 may refer to a wire or a conductor portion on which a facility signal is received, not a separate device.

The external equipment is an apparatus electrically connected to the equipment integrated control device 100 to transmit and receive electric signals having voltage or current. For example, the external equipment may include fire fighting equipment, moving equipment of the building, security equipment, alarm equipment, measuring equipment and other facilities capable of being operated by electricity.

A facility signal is an electrical signal transmitted by an external facility. The facility signal may have a predetermined voltage or current value. The facility signal may have a different voltage value or current value depending on the electrical characteristics of the external facility. For example, a facility signal for a measurement value transmitted by a measurement facility may have a different voltage value from a facility signal transmitted by the fire protection facility.

The comparison unit 120 can determine whether the voltage of the facility signal is equal to or less than the maximum reference voltage. The comparing unit 120 may be electrically connected to the receiving unit 110 that receives the equipment signal. The comparator 120 can receive the maximum reference voltage from a separate device. The maximum reference voltage may be determined experimentally by a predetermined voltage or may be a value set by the user at an arbitrary value.

The comparison unit 120 can determine whether the voltage of the facility signal is equal to or less than the maximum reference voltage and transmit the determination result to the switch unit 130. [ For example, when the voltage of the facility signal is 5V and the maximum reference voltage is 24V, the comparator 120 may determine that the voltage of the facility signal is lower than the maximum reference voltage and transmit it to the switch unit 130.

The switch unit 130 can interrupt the facility signal when the voltage of the facility signal exceeds the maximum reference voltage. In this case, the facility signal is not transmitted to the voltage follower 140.

The switch unit 130 can transmit the facility signal when the voltage of the facility signal is equal to or lower than the maximum reference voltage. In this case, the facility signal may be communicated to the voltage follower 140.

The voltage follower 140 is provided between the switch unit 130 and the distribution unit 150 so that facility signals transmitted from the switch unit 130 can be stably transmitted to the distribution unit 150. The voltage follower 140 may be a non-inverting buffer. Accordingly, the facility signal provided by the switch unit 130 can be transmitted to the distribution unit 150 stably.

The distribution unit 150 can reduce the voltage of the facility signal transmitted by the switch unit 130. [ The distribution unit 150 can distribute the voltage of the facility signal and reduce the voltage of the facility signal. For example, the distributor 150 may include a structure in which a plurality of resistors are connected in series.

The distribution unit 150 may reduce the current of the facility signal. In this case, the distributor 150 may include a plurality of resistors connected in parallel.

The facility signal whose voltage is reduced by the distributor 150 may be transmitted to the controller 160. [

Based on the voltage of the facility signal, the control unit 160 can determine the signal voltage level of the external facility that has transmitted the facility signal.

The signal voltage level may be a reference voltage required to analyze an electrical signal transmitted by a particular external facility. For example, when the signal voltage level of the measuring equipment is 5V, the control unit 160 must determine that the signal voltage level of the measuring equipment is 5V in order to analyze the signal transmitted by the measuring equipment. For example, the control unit 160 can perform AD (Analog to Digital) conversion of the facility signal based on the signal voltage level. The control unit 160 can refer to the conversion formula or the look-up table stored in the memory during AD conversion of the facility signal.

The control unit 160 can determine the signal voltage level based on the voltage of the facility signal reduced by the distribution unit 150. [ Specifically, the control unit 160 can determine the signal voltage level based on the magnitude of the reduced voltage of the facility signal and the predetermined voltage level table.

The predetermined voltage level table may be data stored in the memory included in the controller 160. [ The voltage level table can be set by the user. The voltage level table may be a lookup table indicating a correspondence between the voltage sensed by the controller 160 and the signal voltage level.

The voltage level table may include a plurality of setting ranges for the voltage. For example, the voltage level table may include a first setting range, a second setting range, and a third setting range. Each setting range may be a range that does not overlap each other. For example, the first setting range may be in a range of more than 0 to 1.5 V, the second setting range may be in a range of more than 1.5 to 3.5 V, and the third setting range may be in a range of more than 3.5 to 5 V .

Each setting range can correspond to a specific signal voltage level. For example, the first setting range corresponds to the first signal voltage level, the second setting range corresponds to the second signal voltage level, and the third setting range corresponds to the third signal voltage level. For example, the first signal voltage level corresponding to the first setting range may be 5V. And the second signal voltage level corresponding to the second setting range may be 12V. And the third signal voltage level corresponding to the third setting range may be 24V.

The control unit 160 can determine where the voltage of the facility signal reduced by the distribution unit 150 is included in the plurality of setting ranges included in the voltage level table. The control unit 160 can determine that the signal voltage level corresponding to the setting range including the reduced facility signal voltage is the signal voltage level of the external facility that transmitted the facility signal.

For example, when the voltage of the equipment signal reduced by the distributor 150 is 1 V, the first setting range is 0 to 1.5 V, and the first signal voltage level corresponding to the first setting range is 5 V, The controller 160 can determine that the signal voltage level of the external equipment is 5V.

The control unit 160 can analyze the facility signal based on the determined signal voltage level. The control unit 160 may analyze the equipment signal by performing operations that are performed in the process of the controller 160 analyzing the information represented by the equipment signal and performing various types of determination based on the information. For example, the control unit 160 can determine the temperature measured by the measurement facility by analyzing the facility signal corresponding to the information about the temperature transmitted by the measurement facility.

For example, analyzing the facility signal by the control unit 160 may include performing AD conversion on the facility signal. The reference voltage for AD conversion of the facility signal can be changed according to the determined signal voltage level. At the AD conversion of the facility signal, the control unit 160 can refer to the conversion formula or the look-up table stored in the memory.

In the practice of the present invention, the external equipment may have different electrical characteristics, so that the electrical characteristics of the equipment transmitted by the external equipment may vary. In order for the controller 160 to analyze equipment signals having various electrical characteristics, it is necessary to determine what electrical characteristics the received equipment signals have. What the controller 160 must determine in order to interpret the facility signal is the signal voltage level. The signal voltage level can indicate the electrical characteristics of external equipment or equipment signals. For example, the signal voltage level may be a unique voltage value of a facility signal. The equipment signal and the external equipment may have a unique current value as an electrical characteristic. In this case, the control unit 160 may determine the signal current level.

The output unit 180 can output at least one of video and audio. The output unit 180 may include at least one of a display unit for outputting an image and an acoustic output unit 180 for outputting sound. The display unit may include a device capable of outputting at least one of an image, a symbol, a character, an image, and a moving image. The sound output unit 180 may include a speaker, a buzzer, and the like.

The control unit 160 can output an error alarm through the output unit 180 when the magnitude of the reduced voltage of the equipment signal does not correspond to the voltage level table. The error alarm may include at least one of an image and a sound indicating that an error has occurred to the user. The fact that the magnitude of the voltage does not correspond to the voltage level table means that there is no setting range including the voltage received by the controller 160 among the plurality of setting ranges included in the voltage level table. That is, when a facility signal having a voltage that can not be determined by the voltage level table is received, the control unit 160 can determine that an error has occurred.

The control unit 160 may store the determined signal voltage level in the memory. The memory may be included in the controller 160. The control unit 160 can analyze the facility signal or select the voltage level of the control signal using the signal voltage level stored in the memory.

The control unit 160 can select the voltage level of the control signal transmitted to the external equipment based on the determined signal voltage level.

In order for the equipment integrated control apparatus 100 to control an external facility having a specific electrical characteristic, a control signal corresponding to the electrical characteristics of the external facility must be transmitted. The control signal corresponding to the electrical characteristics of the external equipment may be a control signal having the signal voltage level of the external equipment. For example, when the control unit 160 determines that the signal voltage level of the specific external equipment is 24V, the voltage level of the control signal for controlling the specific external equipment may be 24V. In this case, the control unit 160 may select the voltage level of the control signal to be 24 V and transmit the control signal having the voltage level of 24 V to the external equipment through the signal output unit 170.

The signal output unit 170 can provide a control signal corresponding to the voltage level selected by the control unit 160 to the external equipment.

The control unit 160 can provide a control signal to the external equipment through the signal output unit 170. The external equipment that receives the control signal can perform the operation commanded by the control unit 160 based on the control signal.

The control unit 160 may be implemented as an application specific integrated circuit (ASIC), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs) for example, at least one of controllers, micro-controllers, microprocessors, and other electronic units for performing other functions.

The equipment signal transmitted by the external equipment can be received through the receiving unit 110.

The comparing unit 120 may compare the voltage of the equipment signal received through the receiving unit 110 with the maximum reference voltage input through a separate device. A separate device for inputting the maximum reference voltage may be a memory or a separate user input device. The comparator 120 can provide the switch 130 with a signal indicating the result of the comparison. For example, the comparator 120 may be a comparator.

The switch unit 130 can interrupt the facility signal when the voltage of the facility signal exceeds the maximum reference voltage. The switch unit 130 can transmit the facility signal to the voltage follower 140 when the voltage of the facility signal is equal to or less than the maximum reference voltage. The switch unit 130 may be an apparatus or an element for determining whether a facility signal has passed or not based on a facility signal received through the receiving unit 110 and a comparison result transmitted from the comparing unit 120. [

The voltage follower 140 may transmit the equipment signal transmitted from the switch unit 130 to the distributor 150. The voltage follower 140 may allow the voltage of the equipment signal transmitted by the switch unit 130 to be stably input to the distribution unit 150. The voltage follower 140 may be a non-inverting buffer.

The distribution unit 150 can reduce the voltage of the facility signal by distributing it. For example, the distributor 150 may include a resistor in series.

The control unit 160 can receive the reduced voltage value by the distribution unit 150. [ The control unit 160 can determine the signal voltage level of the external equipment based on the reduced voltage of the equipment signal. The control unit 160 can analyze the facility signal based on the determined signal voltage level.

[ The signal output section 170 may include an output signal circuit for transmitting a control signal to an external facility.

3 is a flowchart for explaining a control method of the equipment integrated control apparatus 100 according to the present invention.

The control method of the equipment integrated control apparatus (100) includes a receiving step of receiving a facility signal transmitted by an external facility, a first determining step of determining whether a voltage of the facility signal is equal to or less than a maximum reference voltage, A distribution step of distributing a voltage of the facility signal to reduce the voltage of the facility signal when the voltage of the facility signal is equal to or less than the maximum reference voltage, A second determination step of determining a signal voltage level of the external equipment, and a step of analyzing the facility signal based on the signal voltage level. Each step will be described in detail below.

The receiving unit 110 may receive a facility signal transmitted by the external facility (S110).

A facility signal is an electrical signal transmitted by an external facility. A plurality of external facilities connected to the facility integration control apparatus 100 may have various electrical characteristics. Accordingly, the equipment signal can have various electrical characteristics. For example, a facility signal may have a unique voltage level or current level. The inherent voltage level of the facility signal can be termed the signal voltage level of the external facility that transmits the facility signal.

The facility integration control apparatus 100 must determine the signal voltage level of the external facility that transmits the facility signal in order to analyze and interpret the facility signal. The facility integration control apparatus 100 of the present invention determines the signal voltage limes of the external facility using the facility signal and analyzes the facility signal based on the determined signal voltage level so that various electrical characteristics Can be controlled.

The comparing unit 120 can determine whether the voltage of the equipment signal is equal to or less than the maximum reference voltage (S120).

If the comparing unit 120 determines that the voltage of the equipment signal exceeds the maximum reference voltage, the switch unit 130 may block the equipment signal (S130). Accordingly, the facility signal can not be transmitted to the control unit 160.

When the comparison unit 120 determines that the voltage of the equipment signal is lower than the maximum reference voltage, the switch unit 130 may transmit the facility signal to the distribution unit 150. [ Accordingly, the facility signal can not be transmitted to the distribution unit 150. The facility signal may be transmitted to the distribution unit 150 via the voltage follower 140.

When the comparing unit 120 determines that the voltage of the equipment signal is lower than the maximum reference voltage, the distributing unit 150 may reduce the voltage of the equipment signal to be received (S140).

The distribution unit 150 can reduce the voltage of the facility signal by distributing the voltage of the facility signal.

The control unit 160 can sense the voltage of the facility signal reduced by the distribution unit 150. [ The control unit 160 can determine the signal voltage level of the external equipment based on the reduced voltage of the equipment signal. The control unit 160 can determine the signal voltage level based on the magnitude of the reduced voltage of the equipment signal and the predetermined voltage level table.

The voltage level table may include a plurality of setting ranges. The control unit 160 can determine the signal voltage level of the external equipment by determining which setting range the reduced voltage is included in.

For example, the voltage level table may include a first setting range, a second setting range, and a third setting range. At this time, the respective setting ranges do not overlap.

The controller 160 can determine whether the reduced voltage is within the first setting range (S150). For example, when the voltage of the reduced facility signal is 1 V and the first setting range is 0 to 1.5 V, the controller 160 can determine that the reduced voltage is within the first setting range.

If the reduced voltage is within the first setting range, the control unit 160 can determine that the signal voltage level of the external equipment is the first signal voltage level set in accordance with the first setting range (S160).

For example, when the reduced voltage is included in the first setting range and the predetermined first signal voltage level corresponding to the first setting range is 5V, the control unit 160 determines that the signal voltage level of the external equipment is 5V It can be judged.

The controller 160 may determine whether the reduced voltage is within the second set range (S170). For example, when the voltage of the reduced facility signal is 2 V and the second setting range is 1.5 to 3.5 V, the controller 160 can determine that the reduced voltage is within the second setting range.

If the reduced voltage is within the second setting range, the controller 160 may determine that the signal voltage level of the external equipment is a second signal voltage level that is set in accordance with the second setting range (S180).

For example, when the reduced voltage is included in the second set range and the predetermined second signal voltage level corresponding to the second set range is 12V, the controller 160 determines that the signal voltage level of the external equipment is 12V It can be judged.

The control unit 160 can determine whether the reduced voltage is within the third setting range (S190). For example, when the voltage of the reduced facility signal is 4 V and the first setting range is 3.5 to 5 V, the controller 160 can determine that the reduced voltage is within the third setting range.

If the reduced voltage is within the third setting range, the control unit 160 may determine that the signal voltage level of the external equipment is the third signal voltage level set in accordance with the third setting range (S200).

For example, when the reduced voltage is included in the third setting range and the predetermined third signal voltage level corresponding to the third setting range is 24V, the controller 160 determines that the signal voltage level of the external equipment is 24V It can be judged.

If the reduced voltage is not included in the setting range included in the voltage level table, the control unit 160 can output an error alarm through the output unit 180 (S210).

The fact that the reduced voltage is not included in the setting range included in the voltage level table means that the size of the reduced voltage does not correspond to the voltage level table.

When the signal voltage level is determined and selected, the controller 160 analyzes the facility signal based on the selected signal voltage level, and stores the selected signal voltage level in the memory (S220).

 The control unit 160 can select the voltage level of the control signal transmitted to the external equipment based on the signal voltage level. In order for the controller 160 to control the external equipment, a control signal corresponding to the signal voltage level of the external equipment must be transmitted.

The signal output unit 170 can provide a control signal corresponding to the voltage level selected by the control unit 160 to the external equipment.
