As a communication means for performing communication by tone signals between the remote operation means 10 and the CPU 2 of FIG. 2, a DTMF (Dual Tone Multi-Frequenc)
y) A receiver 4 and a DTMF transmitter 5 are provided.

On the other hand, when the control parameter adjustment by the remote control means 10 is inconvenient, the setting input means 6 for performing the adjustment instead of the adjustment input means 6 and the adjustment of the control parameter value by the setting input means 6 are possible. And a setting input changing means 7 for inputting a change command to the CPU 2, and the control device 1 uses the date and time set by the remote operation means 10 or the setting input means 6 as the control parameter. A clock IC 8 is provided as a clock means for supplying the time data required by the CPU 2 when controlling.

FIG. 2 shows the configuration of the remote control means 10.

The remote control means 10 is a CPU of the control device 1.
D, which is a communication means for communicating with 2 using a tone signal
TMF transmitter 11 and DTMF receiver 12, CPU which communicates with CPU 2 by this communication means and performs necessary processing
13, a display device 14 including a display device such as a liquid crystal for displaying various information such as control parameters read from the memory 3 based on the processing of the CPU 13, and the display device 1.
An input device 15 for adjusting the control device 1 by setting and changing the values of the control parameters while referring to the display information of No. 4 is provided.

The remote control means 10 is connected via a cable including a power supply line fed from the power supply of the control device 1,
It can be connected to the control device 1.

The CPU 2 of the control device 1 normally accepts the setting input from the remote operating means 10 as a control parameter in preference to the setting input of the setting input means 6.

Next, the adjustment of the control parameters of the control device 1 performed by the remote control means 10 will be described with reference to FIG.

FIG. 3 is a diagram showing an example of a target control pattern when the control device 1 controls the operation of an automatic door as a driven object, with the horizontal axis representing the position of the automatic door and the vertical axis representing its speed. Is. Here, the speed is the forward direction when the door moves in the closing direction. For example, in the control pattern, the position is 0 at the fully closed position of the door and F at the fully open position, and in the process between them, acceleration is stopped from the fully closed position 0 toward the opening direction, and acceleration stops when the opening speed V _O is reached. The point is A, the deceleration start point at which deceleration starts from the constant speed toward the fully open position is B, and the deceleration start point is held open for a time determined by the fully open position F (open holding time), and then toward the closing direction. Is accelerated,
The acceleration stop point when reaching the closing speed V _C is C, and the deceleration start point at which deceleration starts from the constant speed toward the fully closed position 0 is D,
The creeping start point at which the creeping speed V _T shifts before the fully closed position 0 is E. These points A, B, C, D, and E are control parameters whose values are determined by learning the operation of the door once (hereinafter referred to as "motion learning"). This operation learning is performed by setting the value (for example, the value already stored in the memory 3 or the value to be set) which is displayed on the display device 14 of the remote operation means 10 by the operator when the control device 1 is installed. While referring to the input value, a simulated numerical value such as the above speed is input by the input device 15, and is transmitted to the CPU 2 of the control device 1 together with the door start change command to operate the door.

By repeating the trial of the door with the simulated numerical values as described above, the operator finally obtains appropriate parameter values in consideration of the installation conditions such as the weight of the door to be installed and the amount of traffic. It is determined. The determined value is stored in the memory 3 of the control device 1 when the operator inputs it from the input device 15 and gives a storage change command, and the operation learning is completed.

After that, the control device 1 controls the operation of the door in a pattern according to the stored parameter values.

Next, the adjustment of the control parameters performed by the setting input means 6 provided in the control device 1 will be described.

The CPU 2 of the control device 1 takes in the setting input from the setting input means 6 when the operator gives a change command by operating the setting input changing means 7, and by the setting input from the remote operation means 10. The value stored in the memory 3 is rewritten. After that, when the setting input is newly input from the remote control means 10, the setting input is again prioritized and accepted.

As described above, the setting input means 6 is provided so that adjustment can be performed even when it is desired to change the set value in the control device 1 without depending on the remote operation means 10. In this case, the number of control parameters that are the same as or smaller than the control parameters adjusted by the remote control means 10 can be adjusted. As such a setting input means 6, a regulator such as a variable resistor is used according to the type of control parameter.

A push button switch, for example, is used as the setting input changing means 7.

The control device 1 of the embodiment comprises remote control means 10
It is possible to selectively perform the adjustment from either of the remote adjustment by and the setting input means 6 provided in the main body of the control device.

Further, in the embodiment, when the value of the control parameter already stored in the memory 3 is distorted due to the noise as described above or an error occurs in the set value by the setting input means 6. Also, the following measures are taken without human intervention.

A program for the controller 1 to control the driven object is stored in the storage area of the CPU 2.
When the activation signal is input to the control device 1, the control device 1 controls the driven object using the values of the control parameters stored in the memory 3 according to the procedure of this program. Therefore, in the embodiment, the allowable range of the value of each parameter is stored in the storage area, and the value of the parameter stored in the memory 3 and the setting input means 6 are set based on the stored allowable range. It incorporates a procedure to monitor the value of the specified parameters and respond appropriately if necessary. That is, when the value of the parameter stored in the memory 3 exceeds the allowable range due to the above-mentioned noise or the like at the time of executing the program, the value of the parameter set in the setting input means 6 is changed. Check based on the above procedure, adopt this value if it is within the allowable range, and continue the program. Further, when this value also exceeds the allowable range, the value defined within the allowable range is adopted as the value of the control parameter, and the program is continued. In this way, the control of the driven object can be maintained even when the control parameter stored in the memory 3 is disturbed.

Next, in the control device 1 of FIG. 1, consideration is given to reduce noise that tends to occur due to communication with the remote adjusting means.

That is, the control device 1 is provided with the DTMF receiver 4 and the DTMF transmitter 5 and communicates with the remote control means 10 by a tone signal which is less likely to be affected by noise. Here, the DTMF receiver 4 receives the tone signal transmitted from the remote control means 10, and
Converted to a signal that U2 can accept and converted to CPU2
To transmit. On the other hand, when the CPU 2 transmits data to the remote control means 10, the data is transmitted to the DTMF transmitter 5.
Send to. The DTMF transmitter 5 converts this data into a tone signal and transmits it to the remote control means 10.

By performing communication using tone signals in this manner, in addition to the noise reduction effect described above, there is an advantage that multiple communication can be performed without changing the communication means and the wiring means for communication. That is, the remote control means 1
Not only 0, but communication can be achieved by the same wiring means and communication means even if a detection device or the like for detecting the presence or absence of a pedestrian necessary for controlling an automatic door is connected.

Next, setting of the date and time which is one of the control parameters of the control device 1 of the embodiment will be described.

The date and time parameter is for causing the control device 1 to perform the control operation according to the set date and time, and the control operation according to this parameter is achieved by providing the clock IC 8 controlled by the CPU 2. To be done. That is, when the time (including the day of the week) is input from the remote control means 10 at the time of installing or starting the control device 1, the CPU 2 sends a control signal to the clock IC 8 and initializes this to start the timekeeping operation in real time. Let
After that, the CPU 2 sets the clock I at an appropriate timing.
The time data of C8 is read.

On the other hand, the CPU 2 stores the set date and time and the control operation corresponding thereto as a reservation table in the memory 3
Alternatively, it is stored in the storage area of the CPU 2. Then, the time data read as described above is compared with the stored date and time, and the control operation is performed according to the result.

This control operation is as follows.
For example, in the case of an automatic door, the traffic volume of the door generally fluctuates according to the time of day or the day of the week. Therefore, if a control pattern according to the date and time is adopted, the automatic door can be effectively operated.

Specifically, in the case of normal automatic door control during the day, that is, when a passerby approaches the door, the door is automatically opened and closed after passing, and when a person exits the building at night. Only when it is entered from the outside, the door is opened only by operating a predetermined switch.
At midnight, the doors will be closed automatically and locked, and only switches will be operated.

Also, even when the doors are automatically opened, instead of the control pattern for opening the door to the fully open position F as shown in FIG. If a control pattern that opens up to the position H is adopted, an effect of suppressing the dissipation of cooling and heating energy to the outside of the building can be expected. In this control pattern, the operation learning is executed to determine the values of the control parameters such as the acceleration stop points A ′, C ′, the deceleration start points B ′, D ′, etc., and the remote control means 10 or It may be inputted by the setting input means 6 and stored in the memory 3.

Further, it is possible to grasp whether or not there is a change according to the date and time as described above by providing the clock IC 8 or the CPU 2 itself having a time measuring function such as a timer. That is, the installation environment information such as the number of operations accumulated and executed by the control device, the maximum number of operations per unit time, the elapsed time after the installation of the control device, or the temperature is acquired from the sensor or the like and stored in the nonvolatile memory 3. If it is stored, the data can be read by a read request from the remote operation means 10 and displayed on the display device 14, so that the operator can determine the presence or absence of the above-mentioned fluctuation.

These data can be read out not only by the remote control means 10 but also by an appropriate display device provided with a communication means by a tone signal, which is effectively utilized as a standard for the entire operation including maintenance of the control device. It

[0048]

As described above, since the control device of the present invention can be adjusted not only by the remote operation means but also by the setting input means provided in the control device body, the adjustment by the remote operation means is inconvenient. If there is one, it can be dealt with quickly.
In this way, maintenance work can be flexibly dealt with at any time, resulting in stable operation.

Further, when an abnormality occurs in the value of the control parameter stored in the storage device, the value of the control parameter set in the setting input means is adopted, and when the value of this control parameter also has an abnormality. In this case, by adopting a control procedure for continuing the control by adopting the value stored in the storage area of the control unit, the control device can continue the control even if the control parameter is disturbed by a disturbance factor such as noise. . Therefore,
A fail-safe function can be realized.

Further, since the control device is provided with the communication means for performing communication with the remote control means by the tone signal, the noise reduction effect by the tone signal communication can be obtained, and the same communication means and the same wiring means can be obtained. Thus, there is an advantage in that multiplex communication can be performed and an appropriate external device such as a detection device can be easily connected according to the type of driven object and the installation condition.

Depending on the clock means provided in the control device, it is possible to perform control such that a specific date and time and a control pattern performed by the control device match.

Further, when a non-volatile memory is used as a storage device, the installation environment information such as the number of operations executed and accumulated by the control device, the elapsed time after the installation of the control device, or the temperature is obtained from the sensor or the like, and the nonvolatile memory is provided. Can be stored and retained in a sex memory. By reading out the stored information from the remote control means as necessary, it can be utilized as effective data regarding the overall operation including maintenance of the control device.
