Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an annual schedule control device that is capable of controlling a load throughout the year, such as an aeration processor for a septic tank, whose control state needs to be changed according to seasonal changes.

Figures 1 and 2 show the structure of a conventional septic tank. The sewage that flows into the sedimentation separation chamber from the sewage inflow pipe (331) flows into the aeration chamber H via the advection pipe (331). enter,
It is discharged from the outflow pipe η through the settling chamber and the disinfection chamber. - is an aeration proa, which sends air into the aeration room through an aeration pipe. The system is a backwashing device that is used only during cleaning, and when the valve is closed, it blows out air to clean the aeration room. Air is normally fed into the aeration chamber via the aeration pipe 09), thereby supplying the oxygen necessary for the purification activities of microorganisms. However, if the amount of oxygen supplied is insufficient, there is a problem that metabolism by microorganisms cannot be performed through respiration, and the microorganisms do not decompose waste (organic substances), resulting in a decrease in purification ability. When it is low, the amount of oxygen becomes excessive, resulting in excessive aeration, and the P of the effluent water decreases.
There is a problem that the H content decreases and the water quality deteriorates. Therefore, especially in elementary and junior high schools, the amount of sewage inflow decreases during long vacations such as summer vacation and spring vacation, so it is necessary to reduce the rotation speed of the aeration proa (marked 3).On the contrary, on weekdays when the amount of sewage inflow is large It is necessary to increase the rotation speed of the aeration proa (38).'Also, in the summer when the water temperature is high, microorganisms become more active and the amount of respiration increases, so naturally the amount of oxygen supplied increases more than in the winter when the water temperature is low. There is a need.

The non-invention was made in view of the above points, and a)
It is an object of the present invention to provide an annual schedule control device capable of controlling load conditions throughout the year according to seasonal changes, day and night, holidays and weekdays, etc.

The configuration of the present invention will be described below with reference to illustrated embodiments. Third
The figure is a front view showing the front operation panel of the annual schedule control device (3) of the present invention, and FIG. 4 is a block diagram showing the internal structure of the same. In each of the above figures, (1) is a year and month display section, (2) is an hour and minute display section, and is composed of a 7-sekhmet-shaped numeric display. In addition, (3) is the date display section, which is made up of 31 display elements corresponding to the 1st to 31st, and when the current time is displayed, one of the display elements lights up to display the date. It is something to do. (4) is a time setting section, and (5) is a timer setting section, each of which is composed of a plurality of switches (41) to (47) and (51) to (57). Furthermore, (6) is a call switch for displaying the registered contents, (
7) is an oscillation-off switch for forcibly turning off the relay (8). Each of these display sections 11) to (3
) and each operation switch group (41) to (4?) (sl
) to (5?) +81 +71, etc., are connected to a logic operation section (9) that incorporates a clock LSI serving as a timekeeping means. tio) (11+ is the ROM and RAM connected to the logic operation section (9). The logic operation section (9) is supplied with 90 pulses of a constant period from the crystal oscillation circuit (12). θ3) is A power supply section 04) connected to AClooV or a 200v AC power supply is a constant voltage circuit, and 05) is a storage battery for backup during a power outage. (
1 yen is a long-term relay, and the logic operation part (9 ), and its settings cannot be changed.

Next, FIGS. 5 to 11 are flowcharts showing the functions realized by the logic operation section (9), and the Oj RAM shown in the FO_CATE is stored in the ROM +101. First of all, Figure 5 shows the full display, and as shown in the figure, when the power is turned on, the year and month display (1), hour and minute display (2), and day display (3) are displayed. The current time is displayed. and the time setting switch (41
), timer setting switch (51), call switch (6
) and on/off switch (7), control is transferred to a time setting routine, a timer setting routine, a registered content display routine, and a load oscillation/off reversal routine, respectively. Also, which switch (41) (51) tel (71
When neither is pressed, the current time continues to be displayed. When the current time matches the time set in advance by the timer, the relay (8) is turned on and off by a timer operation routine.

FIG. 6 shows a time setting routine. First, the initial setting time is set to 00:00 on January 1, 1982, and when the switch (41) is kept pressed, ) to (46) are pressed. When the year setting switch (42) is pressed, each time the year setting switch (42) is pressed, the year increases by one year starting from 1982. Also, when any of the month setting switch (43), day setting switch (44), hour setting switch (46), or minute setting switch (46) is pressed, the month display, day display, hour display, Increments the minute display by 1. Then, using the advance processing routine shown in Figure 7, for example, the next day of April 30th will be set to May 1st, and the next day of December will be set to January. be. If the switches (42) to (46) are held down, the display is fast-forwarded at about 8 Hz using a 178 second delay timer. By pressing the seconds setting button (47) in time with the time signal, the second unit is reset to 0, and the main unit returns to 0.

Figure 7 shows the advance processing routine used in the above-mentioned time setting routine.When the minute setting reaches 60 minutes, it is returned to 0 minutes and the hour setting is advanced by 1. There is a function that returns this to 0 o'clock at 24 o'clock and advances the date setting by 1, and a function that advances the power setting by distinguishing between large months and small months, and February of leap years and February of normal years. , force setting is 1
It has a function to return it to January and advance the year setting by 1 after February, and a function to return it to 1982 after 2081.

Next, Figure 8 is a flow chart showing a timer setting routine for setting the day and time when the relay (8) is to be turned on.When the timer setting switch (51) is pressed, this routine is executed from the main JJ05 ram. It is initialized to minutes. In the day display section (3), one of the display elements blinks to indicate that the timer can be set for that day. This routine continues when the switch (51) is pressed, the switches (52) to (56)
Determine whether or not is pressed. When the year setting switch (52) is pressed, the year setting is advanced by one year from 1982 each time it is pressed. Also, when any of the force setting switch (53), date setting switch (54), hour setting switch (56), or minute setting switch (57) is pressed, the timer force setting, date setting, and hour setting are set respectively. , and increments the minute setting by one. However, as in the case of the above-mentioned time setting routine, the advance processing routine as shown in FIG. 7 is used to advance the year setting to minute setting as necessary. Switches (52) to (54) (5g
) If you hold down (57), a 1/8 second delay timer will start the display and fast forward the display at about 8Hz. Then, when the date registration switch (55) is pressed, the day and time when the relay (8) is to be turned on is stored in the RAM (
11), and the blinking display element of the date display section (3) turns on. If you press the day setting switch (54) without pressing this day registration switch (55), the day display section (
The display element that was blinking in step 3) is turned off (9), and the display element corresponding to the next day starts blinking. Therefore, once you have completed the registration for one month, only the display element corresponding to the day when the relay (8) is turned on will light up in that month, so on which day of the month will the relay (8) turn on? It is now possible to clearly understand on which day the relay (8) is turned off. In particular, in this example,
As shown in Figure 1, the 31 display elements in the day display section (3) are arranged in groups of 14, so each day of the week overlaps one above the other, so the relay (8) is turned off on Saturdays and Sundays. Relay from Monday to Friday (8)
If you want to change the setting, you can easily and accurately perform the setting operation.

Next, FIG. 9 is a flowchart showing the registered content display routine. When the call switch (6) is pressed, the main
Control is transferred from Gillam to this routine, the first year and month in which relay (8) is programmed to turn off is called, and the display element corresponding to the day in one month when relay (8) is turned on lights up. It looks like this. Each time the call switch (6) is pressed, the force setting is increased by 1, so that the day on which the relay (8) oscillates in each month can be directly read. Furthermore, if the power setting exceeds December,
Due to the advance process routine, the self-answer settings for January of the next year are displayed. Further, when the call switch (6) is not pressed for a predetermined period of time or more, the system returns to the original main screen.

FIG. 10 is a flowchart showing an oscillation-off reversal routine for the relay (8). When the oscillation-off switch (7) is pressed, this routine is entered and the relay (8) is forcibly turned on. When the oscillator-off switch (1) is pressed again, the relay (8) is turned off and the system returns to the main oscilloscope. Also, if the oscillator-off switch (7) is not pressed,
The relay (8) remains forcibly turned on.

Furthermore, Fig. 11 shows a timer operation routine. In this routine, the current year, month, day, hour and minute are first read, and compared with the registration date and time and minute stored in the RAM, the ON time is calculated. If it is Obi, turn on relay (8),
- Otherwise it is intended to switch off the relay (8). It also reads the current date and turns on the long-term relay (Q6) if it is between May 1st and October 31st, and turns on the long-term relay (Q6) if it is between November 1st and April 30th. 16) is turned off.

FIG. 12 shows an example in which the annual schedule control device of the present invention is used to control the rotation speed of an aerated eel in a septic tank. In the figure, aη is a contact that is turned off by relay (8), 08) is a long-term relay (a long-term contact that is turned off by the country), and Q9) is a contact of a 24-hour timer [F]). (Q9) is 0 solar contact points
The contact point (20) is connected in series to η, and the long-term contact point (connected in series to country. It is. This ishiverter (21) is a device that once rectifies the AC voltage supplied from the AC power source and then converts it back into an AC voltage of a desired frequency, and the effective value and frequency of the output voltage can be controlled. be. The aeration generator (38) is driven by the output of the ishiverter (21).
) consists of a ventilation fan and an induction fan, and the rotation speed of the induction fan is controlled according to the frequency of the output voltage of the ishiverter (2), thereby controlling the amount of air blown during the aeration process. It's about to be controlled. Ishibata (2)
11 has an input terminal for controlling the air flow rate of 0A (38) for aeration, and when the input terminal (A) connected to the solar contact point (17) is open, the aeration is The air flow rate of the pump OP connection will be 50% of the maximum output, and this input terminal (
If @ is short-circuited, the air flow rate will be 70% of the maximum output. Furthermore, when the input terminal (23) is short-circuited and the input terminal t241 connected to the long-term contact (181) is short-circuited, the amount of air blown becomes 80% of the maximum output.

FIGS. 13(a) to 13(c) show an example of an annual control schedule for the amount of air blown by the aeration lower. However, in this Fig. 13, for convenience of explanation, it is assumed that the contact point (191 (2G)) of the 24-hour timer Q3 is always closed. This figure shows the change in the amount of air blown from January to December, and as shown in the figure, the period from July 20th to August 31st, which corresponds to summer vacation, and the period from July 20th to August 31st, which corresponds to winter vacation. In late December and early January, as well as in late March and early April, which correspond to spring break, the amount of sewage inflow will decrease, so the air flow rate for 0 aeration units will be limited to 50%. This operation is realized by turning off the solar contact point αη on the day corresponding to the rest period, as shown in FIG. 13(C). FIG. 13(b) shows the long-term contact point αη. (The figure shows the state of 181, and as shown in the figure, the period from May 1st to October 31st is a long-term contact point (1 point becomes positive, so if the solar contact point θη becomes positive during this period) In the case of zero aeration, the air flow rate is 80% of the maximum output, making it possible to increase the amount of oxygen given to microorganisms in the aeration room during the summer when the water temperature is high. The long-term contact point θ is turned off during the period from 1999 to April 30th of the following year, and when the daylight point 0η is turned off during the period from %.

Next, FIGS. 14(a) to 14(c) show an example of a weekly control schedule for the ventilation lid when aeration is 0 (g).

However, in this Fig. 14, the long-term contact point (l@) is assumed to be closed. Fig. 14 (a) shows that the aeration is 0 A (38
This figure shows the change in air flow rate from Monday to Monday of the following week, and as shown in the figure, on Wednesdays, which are public holidays, and Sundays, which are holidays, the air flow rate for 0 aeration is limited to 5096. I try to do that. This operation is accomplished by turning off the sun contact point (17) on days off, as shown in FIG. 14(C). Figure 14(b) shows the contact point (19) of the 24-hour timer 03).
)(20) As shown in the same figure, during the day when the amount of wastewater flowing in is large and the water temperature is high, the contact point θ1 is
The amount of air blown when the aeration is 0A (C) is increased to 7096.

Finally, FIG. 15 is a so-called claim correspondence diagram showing the main components of the present invention in functional form. In the figure, (9A) is a timekeeping means realized by a clock LSI incorporated in the logic operation section (9), and has a function of measuring the current time including at least the month and day. The current time of this timekeeping means (9A) is the sixth
This can be set by the time setting section (4) as shown in the flowchart in the figure. Also (IIA) is RAMtl
The timer setting section consists of a part of the 0-chart (a day storage means for registering the days on which lη is turned on for at least a year, and its memory peaks and troughs are shown in Figure 8 above). (5). Furthermore, (9B) is a date checking means that compares the day measured by the clocking means (9A) with the date registered in the date storage means (IIA), and among the functions realized by the logical operation section (9), In particular, it corresponds to the match matching function between the current time in the timer operating routine and the registered date of RAM (+l) shown in FIG. This is a relay that turns on 0η.Next, (IOA) is a long-term contact (period storage means that stores the period of about half a year that brought the country into a state of shock), which is made up of a part of the ROM flol. 9c) is a period checking means for checking whether the month and day measured by the clocking means (9A) are stored in the period storage means (IOA) and within the period, and is realized by the logical operation section (9). Among the functions shown in FIG. 11, this corresponds to the function of comparing the current date in the timer operation routine with the period from May 1st to October 31st.Furthermore, (16) Long-term contact (18) according to the output of the period verification means (9c)
It is a long-term relay that controls turning on.

The present invention is constructed as described above, and includes a timekeeping means that measures the current time including at least the month and day throughout the year, a day contact point whose oscillation is controlled every -day, and a day point where the day contact point is turned off. day storage means for registering the date throughout the year; day verification means for verifying the date registered in the date storage means; and date verification means for verifying the date registered in the date storage means; and controlling the date contact point based on the coincidence detection output of the day verification means. 8-contact control means, a long-term contact whose oscillation-off state can be switched approximately every six months, a period storage means for registering a period of approximately half a year during which the long-term contact is turned on, and a month and day to be measured by the time-measuring means. Since it is equipped with a period checking means for checking whether it is within the period registered in the period storage means, and a period contact control means for controlling the long-term contact based on the detection output of the period checking means,
Day contacts can be used to change the load output by distinguishing weekdays, Sundays, holidays, etc., and long-term contacts can be used to change the load output between summer and winter, for example, so that the load can be twisted throughout the year. This has the advantage that it is possible to achieve overall energy savings by optimizing the output. As mentioned in the explanation of the embodiment, if the annual schedule control device of the present invention is used to control the aeration of the septic tank to zero, the aeration can be sent to the sun contact point on holidays when the amount of sewage is small. It becomes possible to control to reduce the air volume, and by using a long-term contact point, it becomes possible to control to increase the air flow from the aeration lower in the summer when the water temperature rises.
