For example, one of the viewing location control systems 101 is installed in the management system, and one of the viewing location control systems 101 is installed in the cashier system. The audiovisual place control system 101 installed in the management system controls several of the intelligent control subsystem 102 for the box, the audiovisual place control system 101 installed in the cash register system controls the remaining intelligent control subsystems 102 for the box in the audiovisual place, and finally all the audiovisual place control systems 101 jointly control all the intelligent control subsystems 102 for the box in the audiovisual place.
Any one connection mode can be selected according to the requirements of the actual audio-visual places, personalized adjustment is achieved, and the method is convenient to apply to various audio-visual places.
Because the starting parameters comprise the starting sequence of the equipment and the starting time interval of the equipment, the equipment in the box 103 cannot be started simultaneously, so that the problems of mutual interference of power supplies and signals among the equipment, circuit load caused by overlarge simultaneous starting power of the equipment, circuit tripping, equipment burning and the like are avoided. Meanwhile, the starting operation is executed without manual work in the box 103, so that the personnel investment is reduced, the cost is greatly saved, and the starting efficiency is improved.
Considering that in an actual application scenario, there may be a scenario that a plurality of clients simultaneously open a box and need to open a plurality of boxes 103 simultaneously, or need to open a plurality of boxes 103 once the business begins, and the like, when the audiovisual place control system 101 receives opening instructions of more than two boxes 103, the audiovisual place control system 101 sends starting instructions to the box intelligent control subsystem 102 corresponding to the boxes 103 at intervals, and the box intelligent control subsystem 102 controls all devices in the boxes 103 to start according to the starting parameters. The box 103 and the box 103 cannot be started simultaneously, so that direct interference among the boxes 103 is avoided, equipment in the boxes 103 is protected, and better experience is provided for users.
Further, the following is a specific example with reference to fig. 4, it should be noted that fig. 4 is only a connection situation of one device in the viewing location, and in other embodiments, the device in the viewing location may be variously adjusted, which is not limited.
As shown in figure 4, the device has 10 conventional on-off functions, can be connected with site lighting, air exhaust and external equipment, wherein two paths are on and off, can be connected with 2KW resistive load, and is convenient for the power consumption requirement of the site high-power equipment, 4 paths of small relays can multiplex the control function of an indoor fan of a central air conditioner, two paths of silicon controlled rectifier dimming control circuits can meet the requirements of different light scenes of the site, support power amplification, and a non-central air conditioner infrared control function, so that a control panel or a system can be controlled to the equipment in a bag house, a 3-path L ED lamp strip decoder is arranged in the device, and the requirements of diversified light scenes of the site are met.
In the present embodiment, the order of starting the devices and the time interval between the starting of the devices are not fixed. But sets the start-up sequence of the equipment in the box 103 according to the equipment interference characteristics; the device interference characteristics include: interference degree to the circuit and interference degree by the circuit;
the equipment with high circuit interference degree is started preferentially, and the equipment with high circuit interference degree is started in a lagging mode;
setting the starting time interval of the equipment in the box 103 according to the equipment interference characteristic;
the time interval between the device with high circuit interference degree and the next device to be started is larger than the time interval between the device with low circuit interference degree and the next device to be started.
As shown in fig. 4, it may be necessary to turn on the set-top box, television, lights and sound, and the following turn-on sequence and time intervals may be set.
1) The light is turned on and the lamp light is turned on,
2) after an interval of 3s, the television was turned on,
3) after the interval of 2s, the set-top box is turned on,
4) after an interval of 1s, the stereo was turned on.
The starting is prioritized when the interference of the light circuit is large, and the starting is delayed when the interference of the sound circuit is large. The interference degree of the light to the circuit is larger, so the television is started after the interval of 3s, and the interference degree of the television to the circuit is smaller than the interference degree of the light to the circuit, so the set top box is started after the interval of 2 s.
It should be noted that when other devices are added, the starting sequence of the devices and the starting time interval of the devices are changed. Such as: when it is necessary to turn on the set-top box, the television, the lights, the air conditioner, and the sound, the following turn-on sequence and time intervals may be set.
1) The light is turned on and the lamp light is turned on,
2) after the interval of 5s, the air conditioner is started,
3) after an interval of 3s, the television was turned on,
3) after the interval of 2s, the set-top box is turned on,
4) after an interval of 1s, the stereo was turned on.
Similarly, when a device exits, the starting sequence of the device and the starting time interval of the device are correspondingly changed. Such as: when the set-top box, the television and the sound box need to be started, the following starting sequence and time intervals can be set:
1) the television is turned on and the television is turned on,
2) after the interval of 2s, the set-top box is turned on,
3) after an interval of 1s, the stereo was turned on.
The starting sequence and the time interval of the equipment are set individually, the starting time intervals of all the equipment are not the same, but the equipment can be adjusted individually according to the difference of the interference degree of the equipment on the circuit, and the starting sequence is not fixed, so that when other equipment is added or quitted in an audio-visual place, the corresponding adjustment can be carried out, the safety of the circuit is ensured, and the equipment does not interfere with each other.
As shown in fig. 4, the intelligent control subsystem 102 for a box comprises a sequencer, each interface of the sequencer is sequentially connected to a device requiring sequence control in the box 103, and the sequencer adopts an independent zero-live wire access circuit. The method specifically comprises the following steps: for devices whose contents of the box 103 are susceptible to interference such as: the sound box, the set-top box and the television can be connected with the time sequence device, and because the time sequence device adopts an independent zero-live line access circuit, the interference among the devices is further isolated, and the safety of the devices is ensured.
In this embodiment, before the start parameters of all the devices in the box 103 are prestored in the intelligent control subsystem 102 of the box, the method further includes the following steps: the audiovisual place control system 101 or the box intelligent control subsystem 102 presets the number of interfaces of the sequencer. The number of interfaces of the chronograph can be preset, so that the flexibility and expandability of the whole circuit are greatly improved, and personalized protection of each device can be realized. Such as: when the equipment needing to be connected with the time sequence device is added in the box 103, the number of interfaces of the time sequence device can be increased; or the equipment needing to be connected with the time sequence device is reduced in the box 103, so that the number of interfaces of the time sequence device can be reduced, and the time sequence device interfaces can be adjusted in an extensible mode according to actual requirements.
Further, as shown in fig. 5, due to the characteristics of the alternating current, periodic positive and negative voltage transformation occurs, and voltage peaks and voltage troughs occur, where the voltage is highest at the peak and the trough, and the peak voltage
Trough voltage
The voltage zero condition, also called zero crossing, occurs during the voltage variation. The device is started to charge and discharge, and the instantaneous current is maximum. If the relay is closed at the wave crest or the wave trough, the voltage is maximum, the current is maximum, and the impact on the contact of the controller and the circuit is maximum. If the relay is closed at the zero crossing point, the voltage is zero, the current is zero, and when the subsequent voltage changes, the circuit is already conducted, so that the impact on the relay contact and the circuit is minimum. Therefore, each interface of the time sequence device is connected with a relay, and after the intelligent control subsystem 102 of the box receives a box 103 opening instruction, each interface of the time sequence device starts the correspondingly connected equipment when the relay passes through zero. Thus, the impact on the equipment and the circuit is minimized, and the equipment and the circuit are protected.
Further, the equipment of each box 103 may be different, etc., due to considerations of replacement of equipment within the box 103. Before the starting parameters of all the devices in the box 103 are prestored in the intelligent control subsystem 102 of the box, the method further comprises the following steps: the start parameters of all the devices in the box 103 are set or modified by the audio-visual place control system 101, and the set or modified start parameters are sent to the box intelligent control subsystem 102 corresponding to the box 103. By doing so, after the equipment in the box 103 is replaced, the starting parameters of the equipment can be updated in time, so that the equipment and the circuit are protected.
Referring to fig. 4 to 8, in the present embodiment, an embodiment of a cabin intelligent control subsystem 600 is as follows:
a compartment intelligent control subsystem 600, wherein startup parameters of all devices in a compartment are prestored in the compartment intelligent control subsystem 600, and the startup parameters comprise: the device name, the starting sequence of the devices and the starting time interval of the devices;
after the intelligent control subsystem 600 receives the corresponding car opening command, the intelligent control subsystem 600 controls all the devices in the car to be started according to the starting parameters.
Because the starting parameters comprise the starting sequence of the equipment and the starting time interval of the equipment, the equipment in the box can not be started simultaneously, the mutual interference of power supplies and signals among the equipment is avoided, and the problems of line tripping, equipment burning and the like caused by overlarge circuit load due to larger simultaneous starting power of the equipment are solved. Meanwhile, the starting operation is carried out in the box without manpower, so that the personnel investment is reduced, the cost is greatly saved, and the starting efficiency is improved.
In the present embodiment, the order of starting the devices and the time interval between the starting of the devices are not fixed. But sets the starting sequence of the devices in the box according to the interference characteristics of the devices; the device interference characteristics include: interference degree to the circuit and interference degree by the circuit;
the equipment with high circuit interference degree is started preferentially, and the equipment with high circuit interference degree is started in a lagging mode;
setting a starting time interval of equipment in the compartment according to the equipment interference characteristic;
the time interval between the device with high circuit interference degree and the next device to be started is larger than the time interval between the device with low circuit interference degree and the next device to be started.
As shown in fig. 4, it may be necessary to turn on the set-top box, television, lights and sound, and the following turn-on sequence and time intervals may be set.
1) The light is turned on and the lamp light is turned on,
2) after an interval of 3s, the television was turned on,
3) after the interval of 2s, the set-top box is turned on,
4) after an interval of 1s, the stereo was turned on.
The starting is prioritized when the interference of the light circuit is large, and the starting is delayed when the interference of the sound circuit is large. The interference degree of the light to the circuit is larger, so the television is started after the interval of 3s, and the interference degree of the television to the circuit is smaller than the interference degree of the light to the circuit, so the set top box is started after the interval of 2 s.
It should be noted that when other devices are added, the starting sequence of the devices and the starting time interval of the devices are changed. Such as: when it is necessary to turn on the set-top box, the television, the lights, the air conditioner, and the sound, the following turn-on sequence and time intervals may be set.
1) The light is turned on and the lamp light is turned on,
2) after the interval of 5s, the air conditioner is started,
3) after an interval of 3s, the television was turned on,
3) after the interval of 2s, the set-top box is turned on,
4) after an interval of 1s, the stereo was turned on.
Similarly, when a device exits, the starting sequence of the device and the starting time interval of the device are correspondingly changed. Such as: when the set-top box, the television and the sound box need to be started, the following starting sequence and time intervals can be set:
1) the television is turned on and the television is turned on,
2) after the interval of 2s, the set-top box is turned on,
3) after an interval of 1s, the stereo was turned on.
The starting sequence and the time interval of the equipment are set individually, the starting time intervals of all the equipment are not the same, but the equipment can be adjusted individually according to the difference of the interference degree of the equipment on the circuit, and the starting sequence is not fixed, so that when other equipment is added or quitted in an audio-visual place, the corresponding adjustment can be carried out, the safety of the circuit is ensured, and the equipment does not interfere with each other.
Further, the intelligent control subsystem 600 for the box comprises a time sequence device 601, each interface of the time sequence device 601 is sequentially connected with equipment needing time sequence control in the box, and the time sequence device 601 adopts an independent zero-live wire access circuit. The method specifically comprises the following steps: for devices whose contents are susceptible to interference such as: the sound box, the set-top box and the television can be connected with the time sequence device 601, and because the time sequence device 601 adopts an independent zero-live line access circuit, the interference among the devices is further isolated, and the safety of the devices is ensured.
In this embodiment, before the start parameters of all devices in the box are pre-stored in the intelligent control subsystem 600 of the box, the method further includes the following steps: the intelligent control subsystem 600 for the box presets the number of interfaces of the time sequence device 601. The number of interfaces of the sequencer 601 can be preset, so that the flexibility and expandability of the whole circuit are greatly improved, and personalized protection of each device can be achieved. Such as: when the equipment needing to be connected with the time sequence device 601 is added in the box, the number of interfaces of the time sequence device 601 can be increased; or the number of devices needing to be connected with the time sequence device 601 in the box is reduced, so that the number of the interfaces of the time sequence device 601 can be reduced, and the time sequence device 601 can be subjected to extensible adjustment according to actual requirements.
Further, as shown in fig. 5, due to the characteristics of the alternating current, periodic positive and negative voltage transformation occurs, and voltage peaks and voltage troughs occur, where the voltage is highest at the peak and the trough, and the peak voltage
Trough voltage
The voltage zero condition, also called zero crossing, occurs during the voltage variation. The device is started to charge and discharge, and the instantaneous current is maximum. If the relay 602 is closed at a peak or trough, the voltage is at a maximum, the current is at a maximum, and the impact on the controller contacts and circuitry is at a maximum. If the relay 602 is closed at a zero crossing, the voltage is zero and the current is zero, and when the subsequent voltage changes, the circuit has been turned on with minimal impact on the relay 602 contacts and the circuit. Therefore, each interface of the timer 601 is connected with a relay 602, and after the intelligent control subsystem 600 of the box receives a box opening instruction, each interface of the timer 601 starts the correspondingly connected equipment when the relay 602 crosses zero. Thus, the impact on the equipment and the circuit is minimized, and the equipment and the circuit are protected.
Further, the equipment may be different for each box, etc. due to considerations of replacement of equipment within the box. Before the start parameters of all the devices in the box are prestored in the box intelligent control subsystem 600, the method further includes the following steps: and acquiring starting parameters of all equipment in the audio-visual place control system, and if the starting parameters are modified, updating the box intelligent control subsystem 600 to the latest starting parameters. Therefore, after the equipment in the box is replaced, the starting parameters of the equipment can be updated in time, and the equipment and the circuit are protected.
Referring to fig. 9, in the present embodiment, a method for controlling an audiovisual place device is specifically implemented as follows:
step S901: the system is characterized in that more than one audio-visual place control system is arranged in the audio-visual place, more than one box is arranged in the audio-visual place, a box intelligent control subsystem is arranged in each box, each audio-visual place control system is connected with part or all of the box intelligent control subsystems, starting parameters of all devices in each box are prestored in the box intelligent control subsystems, and the starting parameters comprise: the device name, the starting sequence of the devices and the starting time interval of the devices;
and after the audio-visual place control system receives the opening instruction of one of the boxes, the audio-visual place control system sends the opening instruction to the intelligent control subsystem of the box corresponding to the box.
Step S902: and the box intelligent control subsystem controls all the equipment in the box to be started according to the starting parameters.
As shown in fig. 1, in the audiovisual place, one audiovisual place control system may be provided, and the audiovisual place control system is connected with all the intelligent control subsystems of the box.
As shown in fig. 2, when two or more viewing location control systems are provided in a viewing location: and each audio-visual place control system is connected with all the intelligent control subsystems of the boxes.

For example, one of the audiovisual place control systems is installed in the management system, and one of the audiovisual place control systems is installed in the cash register system. The audiovisual place control system installed in the management system controls several of the cabin intelligent control subsystems, the audiovisual place control system installed in the cash register system controls other cabin intelligent control subsystems, and finally all the audiovisual place control systems jointly control all the cabin intelligent control subsystems in the audiovisual place.
Any one connection mode can be selected according to the requirements of the actual audio-visual places, personalized adjustment is achieved, and the method is convenient to apply to various audio-visual places.
Because the starting parameters comprise the starting sequence of the equipment and the starting time interval of the equipment, the equipment in the box can not be started simultaneously, the mutual interference of power supplies and signals among the equipment is avoided, and the problems of line tripping, equipment burning and the like caused by overlarge circuit load due to larger simultaneous starting power of the equipment are solved. Meanwhile, the starting operation is carried out in the box without manpower, so that the personnel investment is reduced, the cost is greatly saved, and the starting efficiency is improved.
Considering that in the practical application scenario, there may be a plurality of clients coming to open packages simultaneously and need to open a plurality of boxes simultaneously, or a plurality of boxes need to be opened when the business begins early, further comprising the steps of:
after the audio-visual place control system receives the opening instructions of more than two boxes, the audio-visual place control system sends the starting instructions to the box intelligent control subsystem corresponding to the boxes at intervals, and the box intelligent control subsystem controls all equipment in the boxes to be started according to the starting parameters. The box and the box can not be started simultaneously, direct interference among the boxes is avoided, equipment in the boxes is protected, and better experience is provided for users.
Further, the method also comprises the following steps:
setting a starting sequence of the equipment in the box according to the equipment interference characteristic; the device interference characteristics include: interference degree to the circuit and interference degree by the circuit;

setting a starting time interval of equipment in the compartment according to the equipment interference characteristic;
the time interval between the device with high circuit interference degree and the next device to be started is larger than the time interval between the device with low circuit interference degree and the next device to be started. As shown in fig. 4, it may be necessary to turn on the set-top box, television, lights and sound, and the following turn-on sequence and time intervals may be set.
1) The light is turned on and the lamp light is turned on,
2) after an interval of 3s, the television was turned on,
3) after the interval of 2s, the set-top box is turned on,
4) after an interval of 1s, the stereo was turned on.
The starting is prioritized when the interference of the light circuit is large, and the starting is delayed when the interference of the sound circuit is large. The interference degree of the light to the circuit is larger, so the television is started after the interval of 3s, and the interference degree of the television to the circuit is smaller than the interference degree of the light to the circuit, so the set top box is started after the interval of 2 s.
It should be noted that when other devices are added, the starting sequence of the devices and the starting time interval of the devices are changed. Such as: when it is necessary to turn on the set-top box, the television, the lights, the air conditioner, and the sound, the following turn-on sequence and time intervals may be set.
1) The light is turned on and the lamp light is turned on,
2) after the interval of 5s, the air conditioner is started,
3) after an interval of 3s, the television was turned on,
3) after the interval of 2s, the set-top box is turned on,
4) after an interval of 1s, the stereo was turned on.
Similarly, when a device exits, the starting sequence of the device and the starting time interval of the device are correspondingly changed. Such as: when the set-top box, the television and the sound box need to be started, the following starting sequence and time intervals can be set:
1) the television is turned on and the television is turned on,
2) after the interval of 2s, the set-top box is turned on,
3) after an interval of 1s, the stereo was turned on.
The starting sequence and the time interval of the equipment are set individually, the starting time intervals of all the equipment are not the same, but the equipment can be adjusted individually according to the difference of the interference degree of the equipment on the circuit, and the starting sequence is not fixed, so that when other equipment is added or quitted in an audio-visual place, the corresponding adjustment can be carried out, the safety of the circuit is ensured, and the equipment does not interfere with each other.
Furthermore, the intelligent control subsystem of the box comprises a time sequence device, each interface of the time sequence device is sequentially connected with equipment needing time sequence control in the box, and the time sequence device adopts an independent zero-live wire access circuit. The method specifically comprises the following steps: for devices whose contents are susceptible to interference such as: the sound box, the set-top box and the television can be connected with the time sequence device, and because the time sequence device adopts an independent zero-live line access circuit, the interference among the devices is further isolated, and the safety of the devices is ensured.
In this embodiment, before the start parameters of all devices in the box are prestored in the intelligent control subsystem of the box, the method further includes the following steps: the audio-visual place control system or the box intelligent control subsystem is preset with the number of interfaces of the chronograph. The number of interfaces of the chronograph can be preset, so that the flexibility and expandability of the whole circuit are greatly improved, and personalized protection of each device can be realized. Such as: when equipment needing to be connected with the time sequence device is added in the box, the number of interfaces of the time sequence device can be increased; or the number of the interfaces of the chronograph is reduced by reducing the devices needing to be connected with the chronograph in the box, so that the time sequence interface can be adjusted in an extensible way according to the actual requirement.
Further, as shown in fig. 5, due to the characteristics of the alternating current, periodic positive and negative voltage transformation occurs, and voltage peaks and voltage troughs occur, where the voltage is highest at the peak and the trough, and the peak voltage
Trough voltage
The voltage zero condition, also called zero crossing, occurs during the voltage variation. The device is started to charge and discharge, and the instantaneous current is maximum. If the relay is closed at the wave crest or the wave trough, the voltage is maximum, the current is maximum, and the impact on the contact of the controller and the circuit is maximum. If the relay is closed at the zero crossing, the voltage is zero,the current is zero, and when the subsequent voltage changes, the circuit is already conducted, so that the impact on the relay contact and the circuit is minimum. Therefore, each interface of the time sequence device is connected with a relay, and after the intelligent control subsystem of the box receives a box opening instruction, each interface of the time sequence device starts the correspondingly connected equipment when the relay passes through zero. Thus, the impact on the equipment and the circuit is minimized, and the equipment and the circuit are protected.
Further, the equipment may be different for each box, etc. due to considerations of replacement of equipment within the box. The method comprises the following steps before the starting parameters of all equipment in the box are prestored in the intelligent control subsystem of the box: the starting parameters of all the devices in the box are set or modified through the audio-visual place control system, and the set or modified starting parameters are sent to the box intelligent control subsystem corresponding to the box. Therefore, after the equipment in the box is replaced, the starting parameters of the equipment can be updated in time, and the equipment and the circuit are protected.
