Detailed Description
To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
According to the utility model discloses an embodiment provides a standby control device. Referring to fig. 1, a schematic structural diagram of an embodiment of the apparatus of the present invention is shown. The standby control apparatus may include: the device comprises a collecting unit and a control unit. For example: and the acquisition unit can be a temperature sensor arranged at the outdoor unit.
Specifically, the collecting unit may be disposed at an outdoor unit of the air conditioner, and may be configured to collect an outdoor ambient temperature of an environment where the air conditioner is located.

For example: the reliability of the air conditioner under the standby condition is further improved and the standby power is dynamically reduced by adjusting the control logic of the air conditioner according to different external environments. If the air conditioner is in a low-power consumption standby state, judging the external environment temperature, and determining how the air conditioner system operates according to the external environment temperature; the reliability of the system starting operation is protected under the condition of meeting the low power consumption standby. Therefore, the influence of the ambient temperature on the air conditioner external unit is fully considered, and the low-power consumption standby mode is changed according to the external ambient temperature; under the condition of not increasing the hardware cost, the reliability of low-power-consumption standby of the air conditioner under severe working conditions is improved.
Therefore, under the condition that the air conditioner receives a shutdown instruction, the outdoor unit of the air conditioner is subjected to standby control according to the relation between the collected outdoor environment temperature and the set temperature range, so that low-power-consumption standby control is realized under the condition that the reliability of the outdoor unit of the air conditioner is ensured, the reliability of the operation of the air conditioner is ensured, and the low-power-consumption control is also dynamically realized.
In an alternative example, the control unit may include: the outdoor unit comprises an outdoor unit controller module, an outdoor unit first power supply branch and an outdoor unit second power supply branch.
Specifically, the first power supply branch of the outdoor unit is arranged between the live wire of the ac power supply and the outdoor unit controller module, and can be used for controlling the connection or disconnection between the live wire of the ac power supply and the outdoor unit controller module according to a first control mode.
Specifically, the second power supply branch of the outdoor unit is also arranged between the live wire of the ac power supply and the outdoor unit controller module, that is, is connected in parallel with the first power supply branch of the outdoor unit, and can be used to control the connection or disconnection between the live wire of the ac power supply and the outdoor unit controller module in the second control manner. The first control mode and the second control mode may be preset control modes or may be realized under the control of the outdoor unit controller module.
The outdoor unit controller module may be provided with a switching power supply and an outdoor unit controller.

For example: when the external machine switch power supply is electrified, the external machine relay K is conducted2After the DC bus voltage reaches a certain voltage, the relay K is switched on3Cut off relay K again2. Because K is directly conducted after the switch power supply is electrified3The impact current is too large, so that the switching power supply is damaged; and the pilot relay K2Due to the presence of RPTCResistance buffer function, after stabilization, turn on K3Not only protects the switch power supply but also avoids RPTCResistance to power loss.

For example: the first outdoor control switch may be a relay K2. A temperature acquisition module which can be a thermistor RPTC。
In addition, a second outdoor control switch may be provided in the second power supply branch of the outdoor unit. For example: a second outdoor control switch, which may be a relay K3. The relay acts as a switch to cut off the power supply to the controller.
Therefore, reliable charging can be realized by arranging the first outdoor control switch and the temperature acquisition module on the first power supply branch of the outdoor unit; and a second outdoor control switch is arranged on a second power supply branch of the outdoor unit, so that low-power-consumption control can be realized after charging is stable, and the outdoor unit is reliable and safe.

The first control scenario: and if the acquired outdoor environment temperature is greater than the upper limit of the set temperature range, controlling the second power supply branch of the outdoor unit to be disconnected after the air conditioner receives the set time of the shutdown instruction. For example: when the air conditioner external unit receives a shutdown instruction, the air conditioner external unit enters a low-power consumption standby mode judgment logic, and when T is reachedAmbient temperature>T1Then, the external machine receives a shutdown instruction and cuts off the relay K after N minutes3. Because the external environment temperature T is at the momentAmbient temperatureGreater than T1The working condition is not badThe external machine has no need of opening the electric heating belt of the chassis and the electric heating belt of the compressor, so that the relay K is directly cut off3Has no influence on the external unit.
The second control scenario: and if the acquired outdoor environment temperature is greater than the lower limit of the set temperature range and less than or equal to the upper limit of the set temperature range, controlling the second power supply branch of the outdoor unit to be kept connected after the air conditioner receives the set time of the shutdown instruction. For example: when the air conditioner external unit receives a shutdown instruction, the air conditioner external unit enters a low-power consumption standby mode judgment logic, and when T is reached2<TAmbient temperature<＝T1When the external machine receives the shutdown instruction for N minutes, the relay K is started3No treatment is done. At the moment, the temperature interval of the external environment is in T2And T1Meanwhile, the outer machine may have the condition that the chassis electric heating belt and the compressor electric heating belt need to be opened, so that the relay K is not needed3And (6) processing.
The third control scenario: and if the acquired outdoor environment temperature is less than or equal to the lower limit of the set temperature range, controlling the second power supply branch of the outdoor unit to be kept connected after the air conditioner receives the set time of the shutdown instruction. For example: when the air conditioner external unit receives a shutdown instruction, the air conditioner external unit enters a low-power consumption standby mode judgment logic, and when T is reachedAmbient temperature<＝T2When the external machine receives the shutdown instruction for N minutes, the relay K is not cut off3. At this time TAmbient temperature<＝T2If K is disconnected, the situation is shown as that the vehicle is in a bad working condition3The outer machine of air conditioner can not open when needing to open chassis electric heating area and compressor electric heating area, causes the condition that the chassis freezes, outer fan freezes and the refrigerant liquefaction in the compressor, when the outer machine is started again, can lead to outer fan stall or system overload, leads to the compressor frequency can't run to the settlement frequency, unable normal start, seriously shortens outer machine of air conditioner life.
Therefore, under the condition that the air conditioner receives a shutdown instruction, the connection or disconnection of the outdoor first power supply branch and the outdoor second power supply branch is controlled by combining the relation between the outdoor environment temperature and the set temperature range, so that the reliability and safety of the outdoor unit can be ensured, and the low-power-consumption standby energy-saving control can be dynamically realized.
In an alternative embodiment, the method may further include: the control unit can also be used for controlling an indoor unit of the air conditioner to send a wake-up signal which can be used for waking up an outdoor unit of the air conditioner under the condition that the air conditioner receives a starting-up instruction, and controlling the indoor unit to charge a switching power supply in an outdoor unit controller module of the outdoor unit; and after the switch power supply in the outdoor unit controller module is electrified, controlling the charging path of the indoor unit for charging the switch power supply in the outdoor unit controller module of the outdoor unit to be disconnected.
Therefore, the outdoor unit is awakened by the indoor unit and the switching power supply in the outdoor unit controller module is charged, so that power consumption can be saved, and energy conservation is facilitated.
In an optional example, the control unit may further include: the indoor unit controller module and the indoor unit power supply branch. For example: in the indoor unit control module, an indoor unit controller and a switching power supply may be provided.
The indoor unit power supply branch is arranged between a communication line of an indoor unit controller module of the air conditioner and a live wire of an alternating current power supply, and can be used for controlling connection or disconnection between the live wire of the alternating current power supply and the indoor unit controller module under the control of the indoor unit controller module of the air conditioner so as to control connection or disconnection of a power supply path for supplying power to the communication line of the indoor unit controller module through the live wire of the alternating current power supply.
Optionally, the controlling unit controls the indoor unit to charge the switching power supply in the outdoor unit controller module of the outdoor unit, and the controlling unit may include: and sending a wake-up signal through the indoor unit controller module, and simultaneously controlling the power supply branch of the indoor unit to be connected so as to charge a switching power supply in the outdoor unit controller module of the outdoor unit.
Alternatively, the controlling unit may control the charging path of the indoor unit to charge the switching power supply in the outdoor unit controller module of the outdoor unit to be disconnected, and the controlling unit may include: and under the condition that a switching power supply in the outdoor unit controller module is electrified, the power supply branch of the indoor unit is controlled to be disconnected so as to ensure normal communication between the indoor unit controller module and the outdoor unit controller module through a communication line.
For example: when the air conditioner receives a starting instruction, the indoor unit sends out a wake-up signal, and meanwhile, the indoor unit switches on an indoor unit relay K1Charging the switching power supply of the external machine in a mode of powering up the communication line; after the main chip of the external machine is electrified, the relay K of the internal machine is disconnected1Thereby ensuring the subsequent communication to be normal.
Therefore, the indoor unit power supply branch is arranged between the live wire of the alternating current power supply and the indoor unit controller module, the switching power supply in the outdoor unit controller module can be charged by controlling the indoor unit power supply branch, the structure is simple, and power consumption is saved.
More optionally, an indoor control switch is disposed on the indoor unit power supply branch. For example: indoor relay, which can be relay K1。
Therefore, the indoor control switch is arranged on the power supply branch of the indoor unit, the structure is simple, and the control mode is simple, convenient and reliable.
Through a large amount of experimental verifications, adopt the technical scheme of the utility model, through the difference according to external environment, the control logic of adjustment air conditioner can be under the condition of guaranteeing air conditioner standby reliability, and the developments reduce standby power to realize the developments energy-conservation under the condition of guaranteeing air conditioning system's operational reliability.

The indoor unit circuit and the outdoor unit circuit adopt independent power supply modes, the power consumption of the outdoor unit circuit is completely reduced to zero by cutting off the outdoor unit power supply in a standby state of the air conditioner, and meanwhile, the power consumption of the indoor unit control circuit is reduced to the minimum by reducing the output voltage of the indoor unit controller power supply, so that the purpose of effectively reducing the power consumption of the air conditioner in the standby state is achieved. When the scheme does not consider the external situation faced by the air conditioner, the power supply of the external unit is cut off only according to the signal given by the internal unit, and then once the internal unit gives the wake-up signal, the external unit is forcibly turned on, the environment where the external unit is located is not judged, and the external unit is possibly damaged and influenced.
In an optional implementation manner, the present invention provides a method and an apparatus for controlling low power standby, and a method and an apparatus for controlling high reliability of low power standby, which further improve the reliability and dynamically reduce standby power under the standby condition of the air conditioner by adjusting the control logic of the air conditioner according to the difference of the external environment. Therefore, the influence of the ambient temperature on the air conditioner external unit is fully considered, and the low-power consumption standby mode is changed according to the external ambient temperature; under the condition of not increasing the hardware cost, the reliability of low-power-consumption standby of the air conditioner under severe working conditions is improved.
Specifically, in consideration of the regional temperature relationship, low-temperature regional air conditioners are generally equipped with a chassis electric heating belt and a compressor electric heating belt; in order to reduce energy consumption, a low-power consumption standby function is required.

Step 2, conducting an outer machine relay K after the outer machine switching power supply is electrified2After the DC bus voltage reaches a certain voltage, the relay K is switched on3Cut off relay K again2. Because K is directly conducted after the switch power supply is electrified3The impact current is too large, so that the switching power supply is damaged; and the pilot relay K2Due to the presence of RPTCResistance buffer function, after stabilization, turn on K3Not only protects the switch power supply but also avoids RPTCResistance to power loss.
Wherein, set up thermistor, mainly for the relay connection after, during the electric current increase, resistance temperature risees, and resistance value risees to guarantee that the resistance can not explode the resistance because of the electric current is too big, can't choose for use as ordinary resistance, because the current restriction.
Step 3, entering a low-power consumption standby mode judgment logic when the air conditioner external unit receives a shutdown instruction, and entering a low-power consumption standby mode judgment logic when T is detectedAmbient temperature>T1Then, the external machine receives a shutdown instruction and cuts off the relay K after N minutes3。
In particular, due to the ambient temperature T at this timeAmbient temperatureGreater than T1The situation shows that the working condition is not bad at the moment, and the outer machine does not have the requirement of opening the electric heating belt of the chassis and the electric heating belt of the compressor, so that the relay K is directly cut off3Has no influence on the external unit.
Alternatively, when T2<TAmbient temperature<＝T1When the external machine receives the shutdown instruction for N minutes, the relay K is started3No treatment is done.
Specifically, the external environment temperature interval is at T2And T1Meanwhile, the outer machine may have the condition that the chassis electric heating belt and the compressor electric heating belt need to be opened, so that the relay K is not needed3And (6) processing.
Alternatively, when TAmbient temperature<＝T2When the external machine receives the shutdown instruction for N minutes, the relay K is not cut off3。
Specifically, at this time TAmbient temperature<＝T2If K is disconnected, the situation is shown as that the vehicle is in a bad working condition3The outer machine of air conditioner can not open when needing to open chassis electric heating area and compressor electric heating area, causes the condition that the chassis freezes, outer fan freezes and the refrigerant liquefaction in the compressor, when the outer machine is started again, can lead to outer fan stall or system overload, leads to the compressor frequency can't run to the settlement frequency, unable normal start, seriously shortens outer machine of air conditioner life.

The outdoor unit controller module may be provided with a switching power supply and an outdoor unit controller. When the switching power supply in the outdoor unit controller module is powered on, the first control method may be: after the first power supply branch of the outdoor unit is controlled to be switched on, the first power supply branch of the outdoor unit is controlled to be switched off until the direct-current bus voltage of the power supply of the air conditioner reaches the set voltage and the second power supply branch of the outdoor unit is switched on; the second control mode may be: and controlling the second power supply branch of the outdoor unit to be switched on under the condition that the voltage of the direct current bus of the power supply of the air conditioner reaches the set voltage.
For example: when the external machine switch power supply is electrified, the external machine relay K is conducted2After the DC bus voltage reaches a certain voltage, the relay K is switched on3Cut off relay K again2. Because K is directly conducted after the switch power supply is electrified3The impact current is too large, so that the switching power supply is damaged; and the pilot relay K2Due to the presence of RPTCResistance buffer function, after stabilization, turn on K3Not only protects the switch power supply but also avoids RPTCResistance to power loss.
Therefore, the first power supply branch of the outdoor unit is controlled to be connected under the condition that a switching power supply in the outdoor unit controller module is dotted through the matching of the first power supply branch of the outdoor unit and the second power supply branch of the outdoor unit, and the first power supply branch of the outdoor unit is controlled to be disconnected after the second power supply branch of the outdoor unit is controlled to be connected after the direct-current bus voltage is stabilized, so that the charging safety and the low-power standby reliability of the outdoor unit are ensured.
Alternatively, in a case where the control unit may be included, the control unit performs standby control on the outdoor unit of the air conditioner, and any one of the following control situations may be included.
The first control scenario: and if the acquired outdoor environment temperature is greater than the upper limit of the set temperature range, controlling the second power supply branch of the outdoor unit to be disconnected after the air conditioner receives the set time of the shutdown instruction. For example: when the air conditioner external unit receives a shutdown instruction, the air conditioner external unit enters a low-power consumption standby mode judgment logic, and when T is reachedAmbient temperature>T1Then, the external machine receives a shutdown instruction and cuts off the relay K after N minutes3. Because the external environment temperature T is at the momentAmbient temperatureGreater than T1The situation shows that the working condition is not bad at the moment, and the outer machine does not have the requirement of opening the electric heating belt of the chassis and the electric heating belt of the compressor, so that the relay K is directly cut off3Has no influence on the external unit.
The second control scenario: and if the acquired outdoor environment temperature is greater than the lower limit of the set temperature range and less than or equal to the upper limit of the set temperature range, controlling the second power supply branch of the outdoor unit to be kept connected after the air conditioner receives the set time of the shutdown instruction. For example: when the air conditioner external unit receives a shutdown instruction, the air conditioner external unit enters a low-power consumption standby mode judgment logic, and when T is reached2<TAmbient temperature<＝T1When the external machine receives the shutdown instruction for N minutes, the relay K is started3No treatment is done. At the moment, the temperature interval of the external environment is in T2And T1Meanwhile, the outer machine may have the condition that the chassis electric heating belt and the compressor electric heating belt need to be opened, so that the relay K is not needed3And (6) processing.
The third control scenario: and if the acquired outdoor environment temperature is less than or equal to the lower limit of the set temperature range, controlling the second power supply branch of the outdoor unit to be kept connected after the air conditioner receives the set time of the shutdown instruction. For example: when the air conditioner external unit receives a shutdown instruction, the air conditioner external unit enters a low-power consumption standby mode judgment logic, and when T is reachedAmbient temperature<＝T2When the external machine receives the shutdown instruction for N minutes, the relay K is not cut off3. At this time TAmbient temperature<＝T2Indicate it is on badUnder bad working conditions, if K is disconnected3The outer machine of air conditioner can not open when needing to open chassis electric heating area and compressor electric heating area, causes the condition that the chassis freezes, outer fan freezes and the refrigerant liquefaction in the compressor, when the outer machine is started again, can lead to outer fan stall or system overload, leads to the compressor frequency can't run to the settlement frequency, unable normal start, seriously shortens outer machine of air conditioner life.
Therefore, under the condition that the air conditioner receives a shutdown instruction, the connection or disconnection of the outdoor first power supply branch and the outdoor second power supply branch is controlled by combining the relation between the outdoor environment temperature and the set temperature range, so that the reliability and safety of the outdoor unit can be ensured, and the low-power-consumption standby energy-saving control can be dynamically realized.
In an alternative embodiment, the method may further include: through the control unit, under the condition that the air conditioner receives a starting-up instruction, an indoor unit of the air conditioner is controlled to send out a wake-up signal which can be used for waking up an outdoor unit of the air conditioner, and the indoor unit is controlled to charge a switching power supply in an outdoor unit controller module of the outdoor unit; and after the switch power supply in the outdoor unit controller module is electrified, controlling the charging path of the indoor unit for charging the switch power supply in the outdoor unit controller module of the outdoor unit to be disconnected.

Optionally, the controlling unit controls the indoor unit to charge the switching power supply in the outdoor unit controller module of the outdoor unit, and the controlling unit may include: sending a wake-up signal through an indoor unit controller module, and simultaneously controlling the connection of an indoor unit power supply branch to charge a switching power supply in an outdoor unit controller module of an outdoor unit;
alternatively, the controlling unit may control the charging path of the indoor unit to charge the switching power supply in the outdoor unit controller module of the outdoor unit to be disconnected, and the controlling unit may include: and under the condition that a switching power supply in the outdoor unit controller module is electrified, the power supply branch of the indoor unit is controlled to be disconnected so as to ensure normal communication between the indoor unit controller module and the outdoor unit controller module through a communication line.
For example: when the air conditioner receives a starting instruction, the indoor unit sends out a wake-up signal, and meanwhile, the indoor unit switches on an indoor unit relay K1Charging the switching power supply of the external machine in a mode of powering up the communication line; after the main chip of the external machine is electrified, the relay K of the internal machine is disconnected1Thereby ensuring the subsequent communication to be normal.
Therefore, the indoor unit power supply branch is arranged between the live wire of the alternating current power supply and the indoor unit controller module, the switching power supply in the outdoor unit controller module can be charged by controlling the indoor unit power supply branch, the structure is simple, and power consumption is saved.
