In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The invention provides a device capable of bidirectionally detecting the position of an air conditioner outdoor unit, taking a household hanging machine as an example, and fig. 1 shows an installation schematic diagram of the device capable of bidirectionally detecting the position of the air conditioner outdoor unit. As shown in fig. 1, the acceleration sensor is fixedly installed in the air conditioner external unit.
Fig. 2 is a schematic diagram illustrating a logical structure of an apparatus for bidirectionally detecting a position of an outdoor unit of an air conditioner, according to an embodiment of the present invention, the apparatus including an acceleration sensor and a controller.
As shown in fig. 2, the controller includes a control module, a power module, an operational amplifier U1, a transistor U2, and a relay RY1.
The output end of the acceleration sensor is connected with the control module and the outer machine controller of the air conditioner respectively, and the outer machine controller of the air conditioner can supply power to the acceleration sensor under the condition that the air conditioner runs.
The power module is connected with the control module and the operational amplifier U1 respectively, and is connected with the acceleration sensor through the relay RY1, and the power module can supply power to the control module, the operational amplifier U1 and the acceleration sensor. It should be noted that, the power module can still supply power to the above elements when the air conditioner stops operating, so as to ensure that the acceleration sensor continuously monitors the position information of the external unit. Under the condition that the air conditioner runs and stops running, power supply can be kept, and the purpose of bidirectionally detecting the position of an air conditioner external unit is achieved.
The inverting input end of the operational amplifier U1 is connected to a power supply line between an external machine controller of the air conditioner and the acceleration sensor, and the non-inverting input end of the operational amplifier U1 is grounded. The output end of the operational amplifier U1 is connected with the base electrode of the triode U2, the emitting electrode of the triode U2 is grounded, and the collecting electrode of the triode U2 is connected with the control end of the relay RY1.
The operational amplifier U1 can detect the voltage of the power supply of the external machine controller to the acceleration sensor, if the voltage is zero, a signal is output to control the triode U2 to be not conducted, in this case, the relay RY1 does not act, and the power supply module can supply power to the acceleration sensor; if the voltage is not zero (the outer machine controller supplies power to the acceleration sensor), a signal is output to control the conduction of the triode U2, in this case, the relay RY1 is disconnected, and the power module does not supply power to the acceleration sensor. The relay RY1 is illustratively a normally closed relay.
The acceleration sensor is fixedly arranged in the air conditioner external machine. If the air conditioner outdoor unit moves or inclines, the acceleration sensor moves or inclines along with the air conditioner outdoor unit, and the current movement acceleration or inclination angle can be acquired, so that the abnormal position information of the outdoor unit can be acquired.
The device of outer quick-witted position of bidirectional detection air conditioner that this embodiment provided can supply power to acceleration sensor respectively through outer quick-witted controller and power module, under the condition of air conditioner out of service, the controller can gather supply voltage and control power module and supply power to acceleration sensor, realizes bidirectional detection air conditioner position to the outer machine abnormal position information of accurate detection, the probability that the outer machine of reduction air conditioner falls from the high altitude, improve the outer machine's of air conditioner life, effectively avoid the loss of lives and property.
Fig. 2 also shows that the control module is connected with the mobile terminal, for example, by wireless communication, and after receiving the acceleration information and the inclination angle information output by the acceleration sensor, the control module can send the acceleration information and the inclination angle information to the mobile terminal. The user can check the information at the mobile terminal and timely make treatment.
As shown in fig. 2, the power supply terminal of the operational amplifier is connected to the power supply module, the ground terminal of the operational amplifier is grounded, and further, the non-inverting input terminal of the operational amplifier is grounded through a resistor R1. The operational amplifier may compare the power supply voltage output by the outer unit controller with the ground voltage to determine whether the outer unit controller is supplying power to the acceleration sensor.
In consideration of improving the accuracy of the acceleration sensor in measuring the position information, the acceleration sensor can be fixedly arranged on the shell of the air conditioner outdoor unit, and the acceleration sensor and the air conditioner outdoor unit are ensured to move synchronously.
In order to facilitate the heat dissipation of the acceleration sensor during working, an air hole is formed in the position, close to the acceleration sensor, of the shell, and an air hole is formed in the position, on the air isolating vertical plate, of the same height as the air hole.
The acceleration sensor can be arranged in a cavity at the side where the outer machine controller is arranged, and is fixed on an outer machine sheet metal by using screws. As shown in fig. 1, an acceleration sensor is fixed to the housing 10, and a vent hole 102 is provided near the acceleration sensor. Because the wind-isolating vertical plate is arranged between the fan and the acceleration sensor, in order to improve the heat dissipation efficiency, the ventilation hole 101 can be formed in the position, at the same height as the ventilation hole, of the wind-isolating vertical plate. Illustratively, the vent 101 may be a louvered vent. Based on above-mentioned ventilation hole structure, make acceleration sensor can fully dispel the heat, prolong acceleration sensor's life.

Illustratively, the control module is an MCU (micro controller Unit).
Fig. 2 also shows an external unit controller, an internal unit controller, a buzzer and a nixie tube of the air conditioner. The outer machine controller is used for controlling the fan and the compressor, and the inner machine controller is used for controlling the buzzer and the nixie tube. The outer machine controller is also in communication connection with the upper computer.
When the air conditioner is operated and the position of the outdoor unit is not obviously changed, the acceleration sensor can send normal position information to the outdoor unit controller through A/D conversion. Then, the outer machine controller transmits corresponding information to the inner machine controller through zero-fire communication, and simultaneously, the outer machine controller transmits position information to the upper computer through 485 communication. And the software of the upper computer can display the position information of the outer machine in real time.
After the inner machine controller receives the correct information, no command is sent out, and the nixie tube still displays the normal temperature. When the position of the outer machine obviously moves or the inclination degree of the outer machine is large, the six-axis acceleration sensor can transmit abnormal position information on X, Y and Z axes to the outer machine controller through A/D conversion, then the outer machine controller transmits corresponding abnormal information to the inner machine controller through zero-fire communication, meanwhile, the outer machine controller transmits the abnormal position information to an upper computer through 485 communication, and abnormal position information of the outer machine and corresponding faults are displayed on upper computer software. The internal machine controller sends out corresponding commands to the nixie tube and the buzzer, the nixie tube displays corresponding error codes (such as 5F), and the buzzer gives an alarm.
The inner machine controller respectively sends corresponding commands to the outer machine controller and the inner fan to control the outer machine and the inner fan to stop working. At the moment, the external machine controller supplies power to the acceleration sensor, the operational amplifier U1 transmits a voltage signal to the triode U2, the triode U2 is conducted, the relay RY1 is disconnected, the power supply module stops supplying power to the acceleration sensor, and only the MCU and the operational amplifier U1 are supplied with power. Meanwhile, the MCU keeps a standby state and does not send any information to the outside.
When the air conditioner stops working, the voltage detected by the operational amplifier U1 is 0, the triode U2 is not conducted, the relay RY1 does not act, the power supply module supplies power to the acceleration sensor, the MCU and the operational amplifier U1 at the same time, the acceleration sensor transmits the position information of the external unit to the MCU through A/D conversion, and the MCU transmits the information to the mobile terminal (such as a mobile phone) through wireless communication so as to remind a user of corresponding operation.
The device for bidirectionally detecting the position of the outdoor unit can accurately detect the information of the abnormal position of the outdoor unit, greatly reduce the occurrence of safety accidents (fire and explosion), effectively avoid property loss, reduce the probability of falling of the outdoor unit of the air conditioner from high altitude, and greatly prolong the service life of the outdoor unit of the air conditioner. The controller and the acceleration sensor used by the device for bidirectionally detecting the position of the external machine have good sealing performance, good ventilation effect and longer service life.
