The popularization of production automation not only includes the automation of a newly built factory, but also includes the automation modification of an existing factory. When some existing factories are automatically modified, due to the restriction of objective conditions such as modification cost and geographic environment, some existing automatic control networks cannot be established, and therefore an automatic equipment control device with convenient arrangement and low use cost is needed.

The superfine grating system is an important protection device of a main sewage treatment unit. As sundries in sewage of a sewage treatment plant are various and the sand content is large, the operation of the superfine grating can easily reach the designed full load degree. At the moment, the grid is frequently washed by the back flushing equipment of the system to remove particle impurities, so that a large amount of clean water is needed for washing the equipment.
The clean water that the sewage plant handled discharge up to standard is selected for use to the washing water, need start the retrieval and utilization water pump in the clear water pond with the clear water pump after handling to the washing water tank of superfine grid, but the distance between washing water tank and the retrieval and utilization water pump is far away (about 500 meters) in this sewage plant, and in the short time (in the work progress) still can't set up the communication network between each PLC interstation, just also can not carry out ethernet connection, this brings the difficulty for the automatic operation of superfine grid system. If an automatic equipment control device which is convenient to arrange and low in use cost can be installed in the superfine grating system, the superfine grating system can automatically run.

The embodiment of the present invention further describes the specific implementation of the wireless remote control signal transmitting module 2 and the external signal detecting module 3.
The cleaning water tank of the superfine grating system related in the embodiment of the invention has four liquid level states from low to high, namely an ultra-low liquid level, a high liquid level and an ultra-high liquid level. Generally, when the cleaning water tank is in an ultra-low liquid level and low liquid level state, the reuse water pump needs to be informed to supply water; when the cleaning water tank is positioned at a high liquid level or an ultrahigh liquid level, the reuse water pump needs to be informed to stop supplying water. The four liquid level states can be indicated by 4 float switches, namely, a first float switch is used for indicating ultrahigh liquid level, a second float switch is used for indicating high liquid level, a third float switch is used for indicating low liquid level, and a fourth float switch is used for indicating ultralow liquid level. Fig. 2 is a schematic wiring diagram of the float switch according to the embodiment of the present invention, and it can be seen from the diagram that when the water in the washing water tank is lower than the ultra-low level, the first float switch is in a closed state, the second float switch is in an open state, the third float switch is in a closed state, and the fourth float switch is in an open state; when the water level in the cleaning water tank is between the ultralow liquid level and the low liquid level, the first floating ball switch is in a closed state, the second floating ball switch is in an off state, the third floating ball switch is in a closed state, and the fourth floating ball switch is in a closed state; when the water level in the cleaning water tank is between the low liquid level and the high liquid level, the first floating ball switch is in a closed state, the second floating ball switch is in an open state, the third floating ball switch is in an open state, and the fourth floating ball switch is in a closed state; when the water level in the cleaning water tank is between a high liquid level and an ultrahigh liquid level, the first floating ball switch is in a closed state, the second floating ball switch is in a closed state, the third floating ball switch is in an open state, and the fourth floating ball switch is in a closed state; when the water in the cleaning water tank is higher than the ultrahigh liquid level, the first floating ball switch is in an off state, the second floating ball switch is in an on state, the third floating ball switch is in an off state, and the fourth floating ball switch is in an on state.
Fig. 3 is a circuit diagram of the external signal detection module 3 according to the embodiment of the present invention, in which four intermediate relays, which are denoted by KA01, KA02, KA03 and KA04, are used, and coils of the intermediate relays are connected in series with four float switches, respectively, and then connected in parallel to a power supply. Specifically, a third float switch for indicating a low liquid level is connected in series with a coil of the intermediate relay KA01, a second float switch for indicating a high liquid level is connected in series with a coil of the intermediate relay KA02, a fourth float switch for indicating an ultra-low liquid level is connected in series with a coil of the intermediate relay KA03, a first float switch for indicating an ultra-high liquid level is connected in series with a coil of the intermediate relay KA04, and the series circuits are connected in parallel to a 24V direct-current power supply.
Fig. 4 is a circuit diagram of the wireless remote control signal transmission module 2 according to the embodiment of the present invention, in which the auxiliary contact of the intermediate relay KA01 is connected in parallel with the auxiliary contact of the intermediate relay KA03, and the parallel circuit is connected in series with the key of the remote controller "ON" (open), forming a first sub-circuit; the auxiliary contact of the intermediate relay KA02 is connected in parallel with the auxiliary contact of the intermediate relay KA04, and the parallel circuit is connected in series with the key of the remote controller OFF to form a second sub-circuit; the first sub-circuit and the second sub-circuit are connected in parallel to a 9V direct current power supply. The auxiliary contact of the intermediate relay KA01 and the auxiliary contact of the intermediate relay KA02 are both normally open contacts, and the auxiliary contact of the intermediate relay KA03 and the auxiliary contact of the intermediate relay KA04 are both normally closed contacts.
Assuming that the washing water tank is in an empty state initially, at this time, the water level is below the ultra-low liquid level, the first float switch is in a closed state, the second float switch is in an open state, the third float switch is in a closed state, and the fourth float switch is in an open state, according to fig. 3, the coil of the intermediate relay KA03 is not electrified, according to fig. 4, the auxiliary contact of the intermediate relay KA03 is a normally closed contact, so that the auxiliary contact of the intermediate relay KA03 is in a closed state under the condition that the coil is not electrified, and the key of the remote controller "ON" is turned ON (since the auxiliary contact of the intermediate relay KA01 is connected in parallel with the auxiliary contact of the intermediate relay KA03, when the auxiliary contact of the intermediate relay KA03 is in a closed state, no matter what state the auxiliary contact of the intermediate relay KA01 is, the analog key of the. The coil of the intermediate relay KA02 is not electrified, and the auxiliary contact of the intermediate relay KA02 is a normally open contact, so that the auxiliary contact of the intermediate relay KA02 is in an open state at the moment; similarly, the coil of the intermediate relay KA04 is charged, and the auxiliary contact of the intermediate relay KA04 is a normally closed contact, so that the auxiliary contact of the intermediate relay KA04 is in an OFF state at this time, and therefore the analog key of "OFF" is not turned on. By integrating the above states, the wireless remote control signal transmitting module 2 can send a control command of water supply to the reuse water pump.
The water tank is constantly added with water, the water level slowly rises to a position between the ultralow liquid level and the low liquid level, the first float switch is in a closed state, the second float switch is in an off state, the third float switch is in a closed state, and the fourth float switch is changed from the off state to the closed state. According to fig. 3, the coil of the intermediate relay KA03 is electrified, the coil of the intermediate relay KA01 is electrified, and according to fig. 4, after the coil of the intermediate relay KA03 is electrified, the normally closed auxiliary contact of the intermediate relay KA03 is changed from closed to open, and after the coil of the intermediate relay KA01 is electrified, the normally open auxiliary contact of the intermediate relay KA01 is changed from open to closed, so that the key of the remote controller "ON" is continuously turned ON. As can be seen from the previous description, the key of the remote controller "OFF" is not turned on at this time. By integrating the states, the wireless remote control signal transmitting module 2 still sends a control command of water supply to the reuse water pump at the moment, and the cleaning water tank continues to add water.
The water in the cleaning water tank is continuously added, and the water level slowly rises to a position between the low liquid level and the high liquid level. At the moment, the first floating ball switch is in a closed state, the second floating ball switch is in an open state, the third floating ball switch is changed from the closed state to the open state, and the fourth floating ball switch is in the closed state. According to fig. 3, the coil of the intermediate relay KA01 is not electrified, and according to fig. 4, after the coil of the intermediate relay KA01 is not electrified, the normally open auxiliary contact of the intermediate relay KA01 is changed from closed to open, and meanwhile, referring to the previous description, the normally closed auxiliary contact of the intermediate relay KA03 is also in an open state, so that the key of the remote controller "ON" is not turned ON any more. Referring to the previous description, the key of the remote controller "OFF" is not turned on at this time either. By integrating the above states, the wireless remote control signal transmitting module 2 does not send a control command for supplying water to the reuse water pump, and does not send a control command for stopping supplying water to the reuse water pump, so that the reuse water pump can continue to add water to the cleaning water tank.
The water tank is continuously added with water, and the water level slowly rises to a position between a high liquid level and an ultrahigh liquid level. At the moment, the first float switch is in a closed state, the second float switch is changed from an open state to a closed state, the third float switch is in an open state, and the fourth float switch is in a closed state. According to fig. 3, the coil of the intermediate relay KA02 is charged, and according to fig. 4, after the coil of the intermediate relay KA02 is charged, the normally open auxiliary contact of the intermediate relay KA02 is turned OFF to be closed, and the key of the remote controller "OFF" is turned on (since the auxiliary contact of the intermediate relay KA02 is connected in parallel with the auxiliary contact of the intermediate relay KA04, when the auxiliary contact of the intermediate relay KA02 is in a closed state, the key of the remote controller "OFF" is turned on regardless of the state of the auxiliary contact of the intermediate relay KA 04). Referring to the previous description, the key of the remote controller "ON" is not turned ON at this time. By integrating the states, the wireless remote control signal transmitting module 2 can send a control command of stopping water supply to the reuse water pump, and the reuse water pump stops adding water to the cleaning water tank.
For some unexpected reason, if the water tank is continuously filled with water, after the water level exceeds the ultrahigh liquid level, the first float switch is changed from the closed state to the open state, the second float switch is in the closed state, the third float switch is in the open state, and the fourth float switch is in the closed state. According to fig. 3, the coil of the intermediate relay KA04 is not electrified, and according to fig. 4, after the coil of the intermediate relay KA04 is not electrified, the normally closed auxiliary contact of the intermediate relay KA04 is changed from open to closed, and the key of the remote controller "OFF" is continuously turned on. Referring to the previous description, the key of the remote controller "ON" is not turned ON at this time. By integrating the above states, the wireless remote control signal transmitting module 2 can continue to send a control command of stopping water supply to the reuse water pump at the moment, and the reuse water pump is required to stop adding water to the cleaning water tank.
The above process is reversed, assuming that the washing water tank is initially in a full tank state, i.e., the water level is above the ultra-high level, and then the washing water tank is waterproof, and the water level gradually decreases. In this process, a person skilled in the art can easily know how to automatically send a control command for adding water or stopping adding water to the reuse water pump according to the change of the four float switches by referring to the above description and the common general knowledge in the art, and therefore, the description is not repeated here.
The device for realizing automatic control equipment by using the wireless transmitter disclosed by the embodiment of the invention can be realized by adding the circuits shown in the figure 3 and the figure 4 on the basis of the common wireless transmitter in the market, and has the advantages of simple realization, convenient use and low implementation cost.
Based on any of the above embodiments, the embodiment of the present invention further provides a device for automatically controlling a device by using a wireless transmitter, wherein the wireless remote control signal transmitting module 2 can also realize multiple transmissions of wireless remote control signals at regular time.
When the distance between the wireless remote control signal transmitting module 2 and the wireless remote control signal receiving module 1 is long or the wireless remote control signal transmitting module 1 is blocked, the wireless remote control signal receiving module 1 is easy to lose the wireless remote control signal, that is, the wireless remote control signal transmitted by the wireless remote control signal transmitting module 2 cannot be received. The wireless remote control signal transmitting module 2 can realize the timed multiple transmission of wireless remote control signals, which is helpful to solve the condition of wireless remote control signal loss.
The embodiment of the present invention will further explain the specific implementation of the wireless remote control signal transmitting module 2.
Fig. 5 is a circuit diagram of a first circuit of the wireless remote control signal transmission module 2 according to the embodiment of the present invention, in which an auxiliary contact of the intermediate relay KA01 is connected in parallel with an auxiliary contact of the intermediate relay KA03, and the parallel circuit is connected in series with a key of the remote controller "ON" and an auxiliary contact of the intermediate relay KA06 to form a third sub-circuit; the auxiliary contact of the intermediate relay KA02 is connected in parallel with the auxiliary contact of the intermediate relay KA04, and the parallel circuit is connected in series with the key of the remote controller OFF and the other auxiliary contact of the intermediate relay KA06 to form a fourth sub-circuit; the third sub-circuit and the fourth sub-circuit are connected in parallel to a 9V direct current power supply. The auxiliary contact of the intermediate relay KA01, the auxiliary contact of the intermediate relay KA02 and the two auxiliary contacts of the intermediate relay KA06 are both normally open contacts, and the auxiliary contact of the intermediate relay KA03 and the auxiliary contact of the intermediate relay KA04 are both normally closed contacts.
Fig. 6 is a circuit diagram of a second circuit of the wireless remote control signal transmission module 2 relating to the embodiment of the present invention, in which the coil of the intermediate relay KA06 is connected in series with the normally closed contact of the time relay KT03, and the series circuit is connected in parallel with the coil of the time relay KT03 to form a fifth sub-circuit; the coil of the time relay KT02 is connected in parallel with the fifth sub-circuit to form a sixth sub-circuit; the sixth sub-circuit is connected in series with a normally closed contact of the time relay KT01 and a normally open contact of the intermediate relay KA05 to form a seventh sub-circuit; the intermediate relay KA05 is connected in series with the normally closed contact of the time relay KT02, and the series circuit is respectively connected in parallel with the coil of the time relay KT01 and the seventh sub-circuit to form an eighth sub-circuit; a normally open contact of the intermediate relay KA01, a normally open contact of the intermediate relay KA02, a normally closed contact of the intermediate relay KA03 and a normally closed contact of the intermediate relay KA04 are connected in parallel respectively to form a ninth sub-circuit; the eighth sub-circuit and the ninth sub-circuit are connected in series and then connected in the 220V alternating-current power supply.
The time relay KT01 is used to set the time period length for timing multiple transmissions, such as 10 seconds, which represents that a certain wireless remote control signal containing control commands will be transmitted repeatedly for a time period of 10 seconds. The intermediate relay KA05 is used to stop the transmission process of a single wireless remote control signal. The time relay KT02 is used to set the starting time of a single wireless remote control signal transmission, such as 2 seconds, which means that the wireless remote control signal transmission process is started every 2 seconds. The time relay KT03 is used to set the duration of a single wireless remote control signal transmission process, such as 1.5 seconds, which means that the single wireless remote control signal transmission process needs to be maintained for 1.5 seconds. The intermediate relay KA06 is used for starting or stopping the transmission process of the single wireless remote control signal.
In the cycle of once regularly transmitting wireless remote control signal many times, supposing that time relay KT 01's coil can delay 10 seconds after getting electric and can trigger the auxiliary switch action (normally open closed, the normally closed is opened), supposing that time relay KT 02's coil circular telegram can delay 2 seconds and can trigger the auxiliary switch action (normally open closed, the normally closed is opened), supposing that time relay KT 03's coil circular telegram can delay 1.5 seconds and can trigger the auxiliary switch action (normally open closed, the normally closed is opened). The length of the period for transmitting the wireless remote control signal for a plurality of times at one time is 10 seconds, and the operation of the corresponding time point in the 10-second period is as follows:
at the 0 th second of the cycle, at the moment, the normally closed contact of the time relay KT01 is in a closed state, the normally closed contact of the time relay KT02 is in a closed state, and the normally closed contact of the time relay KT03 is also in a closed state; a coil of the intermediate relay KA05 is electrified, and a normally open contact of the intermediate relay KA05 is changed into a closed state; a coil of the time relay KT02 is electrified, and after 2 seconds, a normally closed contact of the time relay KT02 is changed from a closed state to an open state; a coil of the time relay KT03 is electrified, and after 1.5 seconds, a normally closed contact of the time relay KT03 is changed from a closed state to an open state; the coil of the intermediate relay KA06 is energized, so that the normally open contact of the intermediate relay KA06 in fig. 5 is in a closed state. Thus, once the circuit of fig. 5 is able to transmit a wireless remote control signal, the present state of the circuit of fig. 6 ensures that the wireless remote control signal is properly transmitted.
At the 1.5 th second of the cycle, the normally closed contact of the time relay KT03 is changed from the closed state to the open state, and the coil of the intermediate relay KA06 is de-energized, so that the normally open contact of the intermediate relay KA06 in fig. 5 is changed from the closed state to the open state. The circuit in fig. 5 will not be able to transmit a wireless remote control signal, i.e. the transmission of the wireless remote control signal is stopped after 0 seconds to 1.5 seconds.
In the 2 nd second of the cycle, the normally closed contact of the time relay KT02 is changed into an open state from a closed state, the coil of the intermediate relay KA05 is powered off, and the normally open contact of the intermediate relay KA05 is changed into an open state from a closed state; a coil of the time relay KT02 loses power, and a normally closed contact of the time relay KT02 is changed into a closed state from an open state; the coil of the time relay KT03 loses power, and the normally closed contact of the time relay KT03 is changed from an open state to a closed state. When the normally closed contact of the time relay KT02 is changed from the open state to the closed state, the coil of the intermediate relay KA05 is electrified again, and the normally open contact of the intermediate relay KA05 is changed from the open state to the closed state. At this time, the state of each electronic device in the circuit is the same as 0 second, and once the circuit in fig. 5 can transmit the wireless remote control signal, the current state of the circuit in fig. 6 can ensure that the wireless remote control signal is normally transmitted. That is, from the 2 nd second of the cycle, the wireless remote control signal resumes transmission.
At 3.5 seconds of the cycle, the operating state of the circuit is the same as at 1.5 seconds.
At the 4 th second of the cycle, the operating state of the circuit is the same as at the 2 nd second.
At 5.5 seconds of the cycle, the operating state of the circuit is the same as at 1.5 seconds.
At the 6 th second of the cycle, the operating state of the circuit is the same as at the 2 nd second.
At 7.5 seconds of the cycle, the operating state of the circuit is the same as at 1.5 seconds.
At the 8 th second of the cycle, the operating state of the circuit is the same as at the 2 nd second.
At 9.5 seconds of the cycle, the operating state of the circuit is the same as at 1.5 seconds.
At the 10 th second of the cycle, the normally closed contact of the time relay KT01 changes from the closed state to the open state, and the coil of the intermediate relay KA06 loses power, so that the normally open contact of the intermediate relay KA06 in fig. 5 changes from the closed state to the open state. The circuit in fig. 5 will not be able to transmit wireless remote control signals. The whole cycle is over.
With reference to fig. 5 and fig. 6, the wireless remote control signal transmitting module 2 in the embodiment of the present invention can repeatedly transmit a wireless remote control signal including a related control command for a plurality of times within a certain time, which not only improves the stability of triggering the remote controller, but also improves the accuracy of receiving the remote control signal.
