When any of these setting modes is selected, The setting mode is displayed on the panel operation display panel 12, the programming stored in the storage device 9 is read, and the operation according to the setting mode is started.

First, regarding the operation of the electric lock setting mode,
A description will be given based on the control flow of FIG. In the electric lock setting mode, manual setting and automatic setting of the electric lock are selected, and the type of the electric lock is automatically set. In FIG. 5, in step S1, it is determined whether or not manual setting and automatic setting are performed. In the case of automatic setting, the process proceeds to step S2, and in the case of manual setting, the process proceeds to step S9. The selected setting mode is displayed on the panel operation display panel 12.
In step S2, it is determined whether the lock is an electric lock or an electric strike lock (a door open / close signal is generated by a reed switch).
If it is an electric strike lock, the process proceeds to step S3, the electric strike lock is set, a flag is set, and the process proceeds to step S4. If it is determined in step S2 that the lock is an electric lock, the process proceeds to step S4.

In step S4, for example, a pulse voltage is applied between the terminals of the solenoid 2a of the electric lock (or electric strike lock) shown in FIG. The process proceeds to step S5, to the output waveforms applied terminals of the solenoid 2a, the, the output waveform from the electric lock state detection circuit 3 ₁ 3n,

For monitoring of the electric lock, a lock signal and an unlock signal, which are pulses of a specific timing, are output from each electric lock in response to a pulse applied between the terminals of the solenoid 2a, and the type is monitored by the output pulse. can do. Details will be described with reference to FIG. Then, step S
Proceeding to 6, the type of the electric lock is determined by the coincidence detection by the logic circuit. If the type of the electric lock can be determined, the process proceeds to step S7, where the type of the electric lock is specified.
If the type of the electric lock cannot be determined, the process proceeds to step S8, and the process ends as an electric lock type setting error. Of course, the procedure may return to step S2 to determine the type of the electric lock again. Then, a similar control flow is executed to determine the type of the next electric lock. The type of electric lock set in this control flow is stored in the storage device 9, and each time the type of electric lock at a predetermined installation position is displayed on the panel operation display panel 12.

If it is a manual setting, the process proceeds to step S9, in which the lock type display is sequentially switched by the setting switch 6, and the process proceeds to step S10. When the electric lock to be set is displayed, the setting switch 6 is depressed. Set the type of electric lock. Similarly, the type of the set electric lock is stored in the storage device 9 and displayed on the panel operation display panel 12. Of course, if the type of the electric lock cannot be determined, there is a possibility that the wiring of the electric lock may be abnormal. Therefore, the abnormal electric lock is inspected.

Next, determination of the type of electric lock will be described with reference to the timing chart of FIG. Depending on the type of the electric lock (normal release electric lock, normal lock electric lock, instant normal release electric lock (non-polarity, presence / absence polarity)), a specific lock signal and unlock signal are output. When a predetermined pulse is applied to the solenoid or the like of the electric lock, a lock signal and an unlock signal from the electric lock are input to the MPU 8, and the coincidence with the previously written lock signal and unlock signal is detected by the logic circuit. The type of the electric lock is discriminated based on whether or not they are compared by the coincidence detecting means.

FIGS. 6 (a) to 6 (h) show timing charts of the normal release type electric lock, the normal lock type electric lock, and the instantaneous normal release type electric lock (non-polarity, presence / absence polarity). ing. First, the normal release type electric lock shown in FIGS. 6A to 6D will be described. In the normal release type electric lock, if a pulse is applied to the terminal of the solenoid 2a, the output pulses shown in FIGS. 3A and 3B are obtained. Then, the micro switch B ₁ is actuated, the locking signal, the output waveform shown in (c) is obtained. In addition, an output waveform shown in FIG. On the other hand, in the normal lock type electric lock shown in FIGS. 6A to 6D, output waveforms of the lock signal and the unlock signal are as follows.
Normally, the waveform is inverted with respect to the release type electric lock. (E) to (h) show the output waveforms of the instant normal release electric lock (non-polarity, presence / absence polarity). As described above, since a specific output waveform is output as a locking / unlocking signal depending on the type of the electric lock, the type of the electric lock can be detected by detecting the coincidence between the locking signal and the unlocking signal.

Next, a method for detecting disconnection and short circuit of the electric lock will be described with reference to FIG. Disconnection of the electric lock, the detection method of a short circuit through the electric lock drive circuit 5, a voltage is applied to the solenoid 2a, monitors the current flowing through the solenoid 2a at a current detection and the overcurrent protection circuit 4 _1. Current detection and overcurrent protection circuit 4 _1, when the voltage to the solenoid 2a is applied, it is determined that the disconnection if the output current is 0, the short circuit is generated when current exceeding the specified value flows Judge that you are doing. The disconnection and short-circuit detection signals are input to the MPU 8 via the input / output circuit 7. Then, based on the disconnection and short circuit detection signals, the panel operation display panel 1
2 is displayed. Also, current detection and overcurrent protection circuit 4 ₁
4 to 4n, protection is provided so that an overcurrent flows through the solenoid 2a and does not cause destruction due to insulation breakdown or the like due to heat generation or the like. Of course, electric lock drive circuit 5 and the current detection and the overcurrent protection circuit 4 ₁ can be constructed by a known circuit.

More specifically, when the electric lock is disconnected / short-circuited, various electric locks are operated by a solenoid or a motor, and the impedance of the electric lock differs for each lock type. Therefore, taking into account the resistance of the wiring cable from the control device to the electric lock, the current detection / overcurrent protection circuit 4
_{In step 1} , the operating current at the time of operation of the electric lock is detected by a window comparator or the like, and disconnection or short circuit can be detected based on whether the current value falls within an appropriate range.

The impedance between the terminals of the solenoid 2a of the electric lock is as shown in FIG. 4, which is 0.3 A (24 V DC) at the time of locking for the energized locking type, and 0.times. A current of 9 A (24 VDC) flows. In addition to the variation of the solenoid, etc., the width of the current detection is set in anticipation that the resistance of the cable in the middle will be added, and the appropriate range is from 0.2A to 1.0A. If a large amount of current flows, it is determined that a short circuit including a layer short circuit has occurred. The detection of the appropriate range is performed by a current detection / overcurrent protection circuit 4 having a window comparator and the like.

Further, regarding the disconnection / short circuit of the locking / unlocking signal and the malfunction of the electric lock, during the locking / unlocking control,
The determination is made in the following procedure while detecting the lock signal / unlock signal as the answer signal.

Hereinafter, a control flow for detecting a short circuit, a disconnection, or an abnormal operation of the electric lock due to the locking / unlocking signal of the electric lock will be described with reference to FIGS. 7 and 8. First, FIG.
In step S1, unlock control is started, and a change in a lock signal, which is an answer signal of the electric lock, is monitored. In step S2, the switch B ₁
If the contact point is in the break state, the process proceeds to step S3,
The change of the unlock signal of the electric lock is monitored. If the switch B ₁ is a makeup state, the process proceeds to step S4, it is determined whether the set locking signal abnormality flag, if it is set the procedure proceeds to step S6, the electric lock outputs a lock signal line Is determined to be in a short-circuit state (step S
6). If the flag has not been set, it is determined that the operation is normal (step S5).

In step S2, switch B
_{If the first} contact is in the makeup state, the process proceeds to step S7,
Set the lock signal abnormality flag. Step S3
In step S8, if the break state remains,
It is determined whether or not the lock signal abnormality flag is set. If the lock signal abnormality flag is not set, the process proceeds to step S10, where it is determined that the unlock signal is broken,
If it is set, the process proceeds to step S9, and it is determined that the unlocking operation of the electric lock is defective.

Next, the locking operation of the electric lock will be described with reference to the control flow of FIG. First, in step S1, locking control is started, and the process proceeds to step S2. In step S2, a change in the unlock signal of the electric lock is detected.
If contact break state of the switch B _1, the process proceeds to step S3, and monitoring changes in the locking signal electric lock, if makeup state, the process proceeds to step S4, whether the lock signal abnormality flag is set If it is set, the process proceeds to step S6, and it is determined that the wiring to which the unlock signal is output is in a short-circuit state. If it is not set, it is determined that the operation is normal (step S5).

In step S2, the switch B
_{If the first} contact remains in the make state, the process proceeds to step S7, where the unlock signal abnormality flag is set. If it is determined in step S3 that the break state is maintained, the process proceeds to step S8, where it is determined whether or not the unlock signal abnormal flag is set. If the unlock signal abnormal flag is not set, Proceeds to step S10, and determines that the wiring for outputting the locking signal is disconnected. If it is set, the process proceeds to step S9, where it is determined that the locking operation of the electric lock is defective.

Next, in the present embodiment, the time for performing the periodic inspection is determined based on the number of times the electric lock is used. The counting of the number of times the electric lock is used will be described based on the control flow of FIG. The number of unlocking operations due to a change in the lock signal of the electric lock is counted. It should be noted that the purpose is to serve as a guide at the time of maintenance and inspection, and an accurate numerical value is not necessarily required. Of course, it is not necessary to store all the usage counts in the nonvolatile memory.

However, even if the number of times of use is reset due to power cutoff or power outage, etc., it is necessary to write in a non-volatile memory or the like (storage device 9) every 1000 counts so that there is no large difference in the reference number. And Display 11
In this case, three digits of 10,000 times or more are displayed, and when the predetermined number of times is reached, it is determined that it is time for maintenance and inspection. As described above, it is possible to determine the timing of the maintenance and inspection based on the number of times the electric lock is used, and to manage the electric lock control system rationally.

The control flow will be described with reference to FIG. In step S1, a change in the lock signal of the electric lock is monitored, and if the lock state is maintained, the process returns to step S1. If the unlock signal has changed, the process proceeds to step S2, and the counter is incremented by "1". Then, the process proceeds to step S3, where a change in the locking signal is monitored. If the electric lock is in the unlocked state, the process returns to step S3, and if the electric lock is in the locked state, the process returns to step S1. In step S4, it is determined whether the count value of the counter has reached a predetermined count value. It is determined whether the count value N satisfies the condition of N <1000. If the condition is satisfied, the process returns to step S4. If the condition of N <1000 is not satisfied,
Proceeding to step S5, 1 is stored in the nonvolatile memory (storage device 9).
Write step up. Then, the process proceeds to step S6, and the display 11 displays the number of times of use of the electric lock. Proceeding to step S17, the counter is reset, and the process returns to step S4 again to determine whether the condition of N <1000 is satisfied.

Therefore, when the locking / unlocking number displayed on the display 11 reaches a predetermined number, the maintenance of the electric lock control system is performed, so that a reasonable maintenance and inspection can be performed. Further, when the number of times of locking / unlocking reaches a predetermined number, diagnosis of the electric lock can be automatically performed. Of course, it is clear that the timing for performing the maintenance and inspection may be set by counting the door open / close signals.

As described above, the present embodiment is a device having a self-diagnosis function of automatically detecting disconnection, short circuit, etc. of the electric lock, and counts the number of times the electric lock is used. Numerical values are displayed, and when the counted value reaches a predetermined value, it is possible to determine the maintenance and inspection time. Further, when the number of times of use reaches a predetermined number of times, the electric lock can be automatically checked.
