  However, in such a conventional entrance / exit management system, when the system goes down due to a power failure, there are changes such as the door being opened and closed and a switch being operated even during the power failure, and the initial settings are restored when the power is restored. Then, a situation occurs in which the system setting state and the device state are not consistent.

  If the system setting status and the device status are not consistent at the time of power recovery, it is necessary to go to the site for equipment that does not match and change it to the system setting status. There is a problem that it takes time and effort to enter.

It is an object of the present invention to provide an input / output management control device, method, and program capable of automatically matching a system setting state and a device state at the time of power recovery after a system failure due to a power failure. To do.

  In order to achieve this object, the present invention is configured as follows. The present invention provides an input / output management control apparatus connected to a transmission line from a center apparatus.

  The entry / exit management control device of the present invention nonvolatilely stores the state of the interlocking source device and the interlocking control unit that controls the interlocking destination device based on the interlocking information set in advance when the state change of the interlocking source device is detected. Change when the state change during power failure is determined by comparing the state before the power failure detected by the state storage unit to be restored and the state before the power failure saved in the state storage unit when power is restored after a power failure And a power recovery processing unit that controls the interlocking destination device based on the state of the subsequent interlocking source device.

  Here, when detecting a state change of any of a plurality of linkage source devices, the linkage control unit controls a single linkage destination device based on preset group linkage information, and the power recovery processing unit When a change in state during a power failure is determined for a plurality of linkage source devices included in the group linkage information, the linkage destination device is controlled based on the changed status of the linkage source device having the highest priority.

  When detecting a state change of a plurality of link source devices included in the group link information, the link control unit controls the link destination device by making the latest state change effective.

  The power recovery processing unit detects the state of the interlocking source device at the time of power recovery when the power is first turned on, compares it with a predetermined initial setting state, and determines the change in the state. The linked device is controlled based on the status.

The present invention provides an entry / exit management control method for an entry / exit management device connected to a transmission line from a center device. The entry / exit management control method of the present invention comprises:
An interlock control step for controlling the interlocking destination device based on the interlocking information set in advance when the state change of the interlocking source device is detected;
A state saving step for nonvolatilely saving the state of the interlocking source device;

The details of the entry / exit management control method and program of the present invention are basically the same as those of the entry / exit management control apparatus of the present invention.

  According to the present invention, the state of the interlocking source device is detected at the time of power recovery, and the state before the power failure that is stored in a nonvolatile manner is detected and compared with the current state of the device. If there is a change, the linkage destination device is linked and controlled based on the linkage information in accordance with the current linkage source device status. Sometimes the system setting state and the device state can be automatically matched, and the normal operation state can be quickly entered.

In addition to the basic “one input and one output” single linkage, there is a “multiple inputs and one output” group linkage, but for group linkage, the state of multiple linkage sources changes during a power failure. If there is a change in the status of multiple linked source devices during a power outage, linked control during power recovery is based on the status change of the linked source device with the highest priority set for multiple linked devices. By doing so, it is possible to automatically match the system setting state and the device state with respect to group linkage.

  FIG. 1 is a block diagram of an entry / exit management system to which the present invention is applied. In FIG. 1, a center device 12 is provided in a facility or building monitoring center 10, and a transmission line 16 is drawn from the center device 12 via a transmission unit 14. Input / output management control panels 18-1, 18-2, 18-3 as installed input / output management control devices are connected.

  The entry / exit management control panels 18-1 to 18-3 are, for example, card readers 20-1 to 20-3 and a door 22-1 for managing person entry / exit, as representatively shown by the entry / exit management control panel 18-1. Electric locks 24-1 to 24-3 provided on ˜22-3 are installed. In the entrance / exit management using the card readers 20-1 to 20-3, for example, if it is a company organization, an ID card in which identification information unique to the employee is written is issued and installed outside the door 22-1. By causing the card reader 20-1 to read the ID card, the employee authentication information registered in advance in the entry / exit management control panel 18-1 and the read information obtained by reading the ID card are compared and collated. Based on this, the electric lock 24-1 is unlocked.

  A security sensor 26 is connected to the entrance / exit management control panel 18-1, so that the surveillance is performed in cooperation with the entrance / exit management of the card readers 20-1 to 20-3 and the electric locks 24-1 to 24-3. I have to. That is, when the ID card is read by the card readers 20-1 to 20-3 and no one is in the building, monitoring by the security sensor 26 is enabled, and a theft detection signal from the security sensor 26 is obtained during that time. Control the output of security alarms.

  In this state, when the employee who went to work the next day reads the ID card with the card reader 20-1, the monitoring by the security sensor 26 is canceled based on the collation match by the authentication process, and at the same time the electric lock 24-1 is unlocked. Become.

  Further, the input / output management control panel 18-1 is connected with, for example, switches 28-1 to 28-4 for turning on / off the illumination as input contacts, and the illuminations 30-1 to 30-30 serving as control loads corresponding thereto. -4 is connected. In this example, the lights 30-1 to 30-4 can be individually controlled corresponding to the switches 28-1 to 28-4, respectively.

  Control of various devices provided in such an entry / exit management control panel 18-1 is performed based on preset interlocking information. The link information is created when the system is started up on the center device 12 side and downloaded to the entry / exit management control panels 18-1 to 18-3.

  FIG. 2 is a block diagram showing the functional configuration of the entry / exit management control panel according to the present invention together with the center apparatus. In FIG. 2, the center apparatus 12 is provided with a communication control unit 32 and an application execution environment 34. The communication control unit 32 is a function realized by the transmission unit 14 of FIG.

  The application execution environment 34 is an environment realized by program control of a computer constituting the center apparatus 12 in FIG. 1. The application execution environment 34 includes a system management unit 36, an initial setting information registration processing unit 38, and interlocking information registration. The function of the processing unit 40 is provided by program control. For the application execution environment 34, a master initial setting information file 42 and a master linkage information file 44 are provided.

  The system management unit 36 inputs / outputs management information obtained from input / output status based on reading information of the card reader in the input / output management control panels 18-1 to 18-3 connected via the transmission line 16 shown in FIG. Collection, storage and management.

  The initial setting information registration processing unit 38 creates an initial setting information file to be downloaded to each of the entry / exit management control panels 18-1 to 18-3 and registers it in the master initial setting information file 42. The linkage information registration processing unit 40 creates a linkage information file to be downloaded to the entry / exit management control panels 18-1 to 18-3 and registers it in the master linkage information file 44.

  The entry / exit management control panel 18-1 according to the present invention is provided with a communication control unit 46 and an application execution environment 48. The application execution environment 48 is an execution environment realized by program control of a computer constituting the entry / exit management control panel 18-1. In this application execution environment 48, a power recovery processing unit 50 and an interlock control unit 52 are provided.

  For the application execution environment 48, an initial setting information file 54 and a linkage information file 56 are provided, and device input / output units 58-1 and 58-2 are further provided. In this example, switches 28-1 to 28-4 for controlling illumination and illuminations 30-1 to 30-4 serving as control loads are connected to the device input / output unit 58-1.

  Further, the card input / output unit 58-2 side is connected to the card reader 20-1, the electric lock 24-1, the security sensor 26, and the like shown in FIG. Further, a nonvolatile memory 60 that functions as a state storage unit is connected to the application execution environment 48.

  When the interlock control unit 52 provided in the application execution environment 48 of the entry / exit management control panel 18-1 detects a change in the state of the interlock source device, the interlock destination is based on the preset interlock information in the initial setting information file 54. Control the equipment. The state change of the interlocking source device when the interlock control is performed by the interlock control unit 52 is stored and stored in the nonvolatile memory 60 that functions as a state storage unit each time a state change is detected.

  As the nonvolatile memory 60, for example, a RAM or the like that has received power backup by a super capacitor is used. As a backup at the time of a power failure, the entrance / exit management control panel 18-1 has a standby power supply by a battery (not shown), and can maintain the control operation with the battery for about 30 minutes at the time of a power failure. The supercapacitor that backs up the nonvolatile memory 60 can save the interlocked state in a nonvolatile manner, for example, for about a week even when a power failure occurs.

  The power recovery processing unit 50 detects the state of the interlocking source device at the time of power recovery after a power failure, compares it with the state before the power failure stored in the nonvolatile memory 60, and determines the change in the state during the power failure. By controlling the interlocking destination device based on the state of the interlocking source device after the change, that is, the state of the interlocking source device operated during the power failure, the state of the device is automatically matched to the system setting state.

Here, in the interlock control by the interlock control unit 52,
(1) Single linkage (2) There are two groups linkage.

  Single linkage is “one input and one output” linkage control that controls one linkage destination device for one linkage source device. A plurality of interlocking destination devices may be controlled for one interlocking source device. On the other hand, the group linkage is “multiple input one output” linkage control for controlling a single linkage destination device in response to a state change of any one of a plurality of linkage source devices.

  In group linkage, post-priority control is performed on inputs from a plurality of linkage sources. In post-priority control, for example, when a single light is controlled by a plurality of switches, the light is turned on when one switch is turned on, the light is turned off when the next switch is turned off, and the light is turned on when another switch is turned on. In this way, a single linkage destination is controlled based on the latest linkage source input in terms of time.

  Here, the interlock control unit 52 and the power recovery processing unit 50 provided in the application execution environment 48 of the entry / exit management control panel 18-1 are realized by execution of a computer program constituting the entry / exit management control panel 18-1. As a hardware environment for executing this computer, a memory such as a ROM, a communication board, and the like are connected to a CPU bus, and a program necessary for input / output management control of the present invention is loaded. When the computer is started, an entry / exit management control program is called from the memory, loaded on the RAM, and executed by the CPU.

  FIG. 3 is a flowchart of the entry / exit management control process according to the present invention, which is executed by, for example, the entry / exit management control panel 18-1 of FIG. 2 when the system power is turned on. In FIG. 3, first, in step S1, a single interlocking source and single interlocking destination start-up process is executed. Next, in step S2, group linkage start-up processing is performed for a plurality of linkage sources and a single linkage destination.

  When this start-up process is completed, whether or not an event has occurred due to an input from the connected device is checked in step S3. If an event has been determined, the process proceeds to step S4 to check whether or not the state of the interlocking source has changed. If it is a change state of the link source, the process proceeds to step S5. After the change state of the link source is stored in the nonvolatile memory 60, the link destination is controlled based on the link information in the link information file 56 in step S6.

  If it is determined in step S4 that the state of the interlocking source is not changed, the process proceeds to step S7, and processing other than the interlocking control is executed. Such processes of steps S1 to S7 are repeated until a stop instruction is issued in step S8.

  Next, the single interlocking startup process in step S1 of FIG. 3 will be described. Corresponding to the single linkage, the initial setting information file 54 shown in FIG. 2 is downloaded and stored in the initial setting information file 54 shown in FIG. 2, and the linkage information file 56 shown in FIG. A single interlocking information file 56-1 shown in FIG. 5 is downloaded and stored.

  The single interlocking initial setting information file 54-1 in FIG. 4 is an example of single interlocking of the illumination switches 28-1 to 28-4 and the illuminations 30-1 to 30-4 in FIG. In the initial setting information file for single linkage 54-1, switches 28-1 to 28-4 indicated by names as linkage destinations are registered, and all of the initial setting states are “off”. In addition, the illuminations 30-1 to 30-4 are registered as interlocking destinations, and the initial setting states are all “off”.

  The single interlocking information file 56-1 in FIG. 5 registers switches 28-1 to 28-4 as interlocking sources, and the state of the interlocking source is a binary state of state 1 and state 2, and state 1 is “off”. , State 2 is “ON”.

  In addition, lighting 30-1 to 30-4 is registered as the interlocking destination, and the states of the interlocking destination are two states, state 1 and state 2, which correspond to the interlocking source state 1 and state 2, and the interlocking destination State 1 is “off”, and state 2 is “lighted”.

  FIG. 6 is an example of state detection information of the link source in the current state before the power failure and at the time of power recovery when a power failure occurs in the entrance / exit management system for single linkage. FIG. 6A shows the state detection information 62 before power failure stored in the nonvolatile memory 60. Only the switch 28-1 that is the interlocking source is “ON”, and the other switches 28-2 to 28-4. Is “off”.

  In contrast to the state detection information 62 before power failure, in the current state detection information 64 of the link source detected at the time of power recovery in FIG. 6B, the detection state of the switch 28-1 is “off”. This is different from the detection state “ON” before the power failure.

  The power recovery processing unit 50 provided in the application execution environment 48 in FIG. 2 detects and discriminates the change from “ON” to “OFF” of the detection state of the switch 28-1 before and after the power failure. Then, “OFF” of state 1 of the lighting 30-1 that is the interlocking destination corresponding to “OFF” of state 1 that is the current detection state of the interlocking source of the switch 28-1 in the single interlocking file 56-1 of FIG. The illumination 30-1 is interlocked and controlled so that

  That is, from the current state detection information before and after the power failure shown in FIGS. 6A and 6B, the switch 28-1 is turned on and off during the power failure. 1 operation is discriminated at the time of power recovery, and the lighting 30-1 is turned off automatically as interlocking control corresponding to turning off the switch 28-1 after the change, and the device state and the system setting state are automatically set. Can be matched.

  FIG. 7 is a flowchart of the single interlocking startup process in step S2 of FIG. In FIG. 7, in the single interlocking startup process, after detecting the current state of the interlocking source in step S1, it is checked in step S2 whether or not power is first turned on. In the case of the first power-on, since the information before power-on is not stored in the nonvolatile memory 60, the process proceeds to step S3 in this case, and the current state of the link source is shown in FIG. It is compared with the setting state of the single link initial setting information file 54-1, that is, the initial setting state.

  If there is a change in the state of the link source in step S5, the process proceeds to step S6, and the link destination is controlled based on the link information. That is, in the power recovery control of the present invention, not only at the time of power failure, but also at the first power-on of the system, by using the linkage source information of the initial setting information file and comparing with the actual detection state, If there is a change in the state, by controlling the interlocking destination based on the interlocking information, the state of the device and the system setting state can be automatically matched even when the system is started up.

  On the other hand, if the power was not turned on for the first time in step S2, that is, if power was restored after a power failure during system operation, the process proceeds to step S4, where the current state of the link source and the nonvolatile memory 60 are stored. If there is a change in the state of the link source in step S5, the process proceeds to step S6, and the link destination is controlled based on the link information.

  Such single linked start-up processing in steps S1 to S6 is repeated until all the single linked source processing is completed in step S7. When the processing is completed, the process returns to the main routine of FIG. The group link startup process of S2 is executed.

  FIG. 8 is an explanatory diagram of a specific event log including processing at the time of power recovery according to the present invention when a device is operated during a power failure, taking single linkage as an example. The event log 66 in FIG. 8A is a process when the switch 28-1 serving as a link source is operated during a power failure.

  In the event log 66, first, as an initial state, the switch 28-1 is turned off, and the illumination 30-1 to be linked is turned off. Subsequently, a switch operation is performed as an event during operation, whereby the state of the switch 28-1 changes from “off” to “on”, and the illumination 30-1 is changed from “off” based on the interlocking information associated therewith. Controlled to “lit”.

  Subsequently, a power failure occurs, and at this time, the interlocking source switch 28-1 is set to “ON” and the illumination 30-1 is set to “ON”. If a switch operation is performed as an event during the power failure, the switch 28-1 changes from “on” to “off”, but the setting state of the link destination remains “lighted” because of the power failure.

  Subsequently, when power is restored, comparison is made between the state “ON” at the time of the power outage and the state “OFF” after power restoration for the interlock source switch 28-1, and the state has changed. Based on the state “OFF”, the lighting 30-1 as the interlocking destination is controlled from “ON” to “OFF”, thereby matching the interlocking source state and the interlocking destination state at the time of power recovery.

  FIG. 8B is a specific example of an event log including a power recovery process according to the present invention when interrupt lighting control is received from the center device during operation before a power failure. In the event log 68 of FIG. 8B, in the initial state, the switch 28-1 is “off” and the illumination 30-1 as the interlocking destination is “off”.

  Since the interrupt lighting control command is received from the center device 12 during this operation, the state of the interlock source switch 28-1 remains “OFF” as in the initial state, but the lighting 30-1 as the interlock destination is The “lighting” is switched from the “lighting off” until then to “lighting” based on the lighting control command by the interrupt control.

  In this state, if a power failure occurs and then the power is restored, the state of the switch 28-1 at the time of the power failure is “off”, the state at the time of power restoration is “off”, and before and after the power failure. Since there is no change in the state, the interlocking lighting 30-1 is not controlled by the interlocking information, and the interlocking destination state by the lighting control performed by the interrupt control from the center device before the power failure is “lighting” Can be continuously maintained even after power is restored.

  Next, the group link startup process in step S2 of FIG. 3 will be described. For this group linkage control, the group linkage initial setting information file 54-2 shown in FIG. 9 is saved by downloading in the initial setting information file 54 of FIG. 2, and the linkage information file 56 of FIG. The group information interlocking file 56-2 shown in FIG.

  Here, taking as an example the case where the single illumination 30-1 is interlocked and controlled for the four switches 28-1 to 28-4 in FIG. 2 as the group interlock, the group interlock initial setting information file 54- in FIG. 2, the switches 28-1 to 28-4 are registered as interlocking sources, and “OFF” is set as the initial setting state. On the other hand, the interlocking destination is a single illumination 30-1, and its initial state is “off” corresponding to the initial state “off” of the interlocking source.

  In the group interlocking information file 56-2 in FIG. 10, two states, state 1 and state 2, are registered for the four switches 28-1 to 28-4 as interlocking sources, and further priorities are set. Regarding the interlocking destination, state 1 and state 2 are registered for a single illumination 30-1.

  FIG. 11 is an example of current state detection information before and after a power failure when a system power failure occurs for a group link between a plurality of switches and a single light. FIG. 11A shows state detection information 70 before power failure stored in the nonvolatile memory 60, and the detection states of all the four switches 28-1 to 28-4 are “ON”.

  FIG. 11B shows the detection state of the switches 28-1 to 28-4 detected after the power recovery. The detection state of the second and fourth switches 28-2 and 28-4 is the state “before power failure detection”. It changes from “On” to “Off”.

  In the power recovery processing unit 50 of FIG. 2 in the group linked start-up process, regarding the change in the detection state before the power failure detection and after the power recovery, Referring to the group link information file 56-2 in FIG. 10, the link source having the higher priority, in this case, based on the detection state “off” of the switch 28-2 having the higher priority, The illumination 30-1 is controlled to be linked to “extinguish”, and even when the group is linked, it is possible to automatically match the system setting state and the device state when power is restored.

  FIG. 12 is a flowchart of the group interlock startup process in step S2 of FIG. In FIG. 12, the group link startup process detects the current state of a plurality of link sources in step S1, and checks in step S2 whether or not power is first turned on.

  If the power is turned on for the first time, the process proceeds to step S3, and since there is no stored information in the nonvolatile memory 60, the current state and the group linkage initial setting information file 54-2 shown in FIG. Compare with the default setting. On the other hand, if the power was not turned on for the first time in step S2, that is, if the power was restored after a system power failure, the process proceeds to step S4, where the current state and the nonvolatile memory 60 are stored for a plurality of linkage sources. Compare the saved state before power failure.

  Subsequently, in step S5, it is checked whether or not there is a change in the state of the plurality of interlocking sources. If there is a change in the state of the link source, the process proceeds to step S6, and the link destination is controlled based on the link information according to the state of the link source having the highest priority. If it is a change in the state of a single interlocking source in step S1, the process proceeds to step S7, and the interlocking destination is controlled based on the state of the interlocking source as in the case of single interlocking.

  Such processing in steps S1 to S7 is repeated until the processing of the plurality of interlocking sources constituting all the group interlocking is completed in step S8. When the processing is completed, the process returns to the main routine of FIG. to go into.

  FIG. 13 is an explanatory diagram specifically showing the state and priority of the link source that may occur during a power failure in the entry / exit management system of FIG. In FIG. 13, three types of interlocking source states are taken as an example in this example: individual line, time schedule, and electric lock. The individual lines correspond to the security sensor 26 and the switches 28-1 to 28-4 shown in FIG. The change in the individual line corresponds to the loop closing with respect to the loop opening, which corresponds to the switches 28-1 to 28-4 in FIG. 1, the loop opening corresponds to the switch on, and the loop closing corresponds to the switch off. .

  In addition to this, for individual lines, alarm and alarm cancellation, patrol operation and patrol operation cancellation, sensor monitoring abnormality occurrence and sensor monitoring abnormality recovery, sensor inspection abnormality occurrence and sensor inspection abnormality recovery are set.

  The time schedule is a monitoring time schedule in which, for example, the monitoring time by the security sensor 26 is valid at night and is canceled during the daytime. Furthermore, for electric locks, there are door opening and door closing, and there is a locking relationship for continuous unlocking, manual unlocking, and temporary unlocking. There is open error recovery.

  Such a state that may change at the time of a power failure in the interlocking source state is determined as appropriate depending on the type of device connected to the input / output management control panel and the control content based on the input of the device other than the example of FIG. be able to.

  Furthermore, the present invention provides a program executed by the entry / exit management control panel 18-1, and this program has the processing contents according to the flowcharts shown in FIGS.

  In the above embodiment, the interlocking relationship between the lighting switch and the lighting is taken as an example as single interlocking and group interlocking, but the present invention is not limited to this, and the entrance / exit management system The appropriate relationship between the interlocking source device and the interlocking destination device applied to the interlock control can be applied as it is to automatically match the system state and the device state at the time of power recovery.

Further, the present invention includes appropriate modifications that do not impair the object and advantages thereof, and is not limited by the numerical values shown in the above embodiments.
