[0121] Thermoelectric effect, so-called thermoelectric effect, is a phenomenon of current or charge accumulation generated when electrons (holes) in a heated object move from a high-temperature zone to a low-temperature zone along a temperature gradient.

[0122] Figure 1 A structure diagram of a head start-up circuit of an integrated compressor is provided in the embodiments of the present application. The head start-up circuit of the integrated compressor is applied in a process of restarting the head of the integrated compressor.

The electrical energy generated during the shutdown of the first handpiece A is stored in the second energy storage module 12. By adjusting the switch module, the second energy storage module 12 is first used to power the second handpiece B.

If the energy stored in the first and second energy storage modules 11, 12 is insufficient to activate the second handpiece, the switch state within the switch module is changed to activate the second handpiece using the energy stored in the first, second, and mains modules, achieving a rapid startup.

[0139] One end of the first switch K0 is connected to one end of the power module 10, and the other end is respectively connected to the first end of the first energy storage module 11, one end of the second switch K01 and one end of the first capacitor C.

[0140] The other end of the second switch K01 is connected with the third end of the first energy storage module 11, the second end of the second energy storage module 12 and the first end of the third switch K02 respectively.

[0141] The other end of the third switch K02 is connected with the third end of the second energy storage module 12, the reverse output end of the first diode D1 and the first end of the inverter N respectively.

[0142] The forward input end of the first diode D1 is connected with the collector of the IGBT transistor IGBT1;

[0143] The gate of the IGBT transistor IGBT1 is in insulation control, and the emitter of the IGBT transistor IGBT1 is connected with the other end of the first capacitor C, the other end of the mains module 10 and the second end of the inverter N respectively.

[0144] The third end of the inverter N is connected with the first end of the first switch group KK1 and the first end of the second switch group KK2 respectively, the fourth end is connected with the second end of the first switch group KK1 and the second end of the second switch group KK2 respectively, and the fifth end is connected with the third end of the first switch group KK1 and the third end of the second switch group KK2 respectively.

[0145] The fourth end, the fifth end and the sixth end of the first switch group KK1 are connected to the first machine head A respectively.

[0146] The fourth end, the fifth end and the sixth end of the second switch group KK2 are connected to the second machine head B respectively.

[0147] According to Figure 2In the power-on stage, the first switch K0, the second switch K01, the third switch K02 and the first switch group KK1 are kept closed, the first head A is turned on, and the temperature difference appears after running for a period of time. The hot spot effect is synchronized to open, and the electric energy generated by the hot spot effect is stored in the first energy storage module 11. The temperature detection unit 133 in the control module 13 detects whether the first head A is overheated. If the first head A appears overheating failure, the first switch K0 is first disconnected, and the power supply module is cut off. The controller 132 controls the IGBT1 to be closed, and the third switch K02 is disconnected, so that the energy in the shutdown process of the first head A is transmitted to the second energy storage module 12. The electric quantity detection unit 131 judges whether the second energy storage module 2 is still charging. The controller 132 reads the value of the electric quantity detection unit 131 at a certain time interval. If the absolute value of the difference between the two values is less than the threshold value V, it is judged that the second energy storage module 12 is not charging. If it is no longer charging, it means that the energy of the first head A shutdown has been completely transmitted to the second energy storage module 12, then the first switch group KK1 is disconnected, the first head A is cut off, and the second switch group KK2 is closed, the second head B is connected, and the second head B is started. The electric quantity detection unit 131 judges whether the electric quantity of the second energy storage module 12 can start the second head B. If it can, the second head B is started by using the second energy storage module 12, and then the first switch K0, the second switch K01 and the third switch K02 are closed, and the second head B is continuously run by using the power supply unit 101. If the energy of the second energy storage module 12 is not enough to start the second head B, the second switch K01 is disconnected, and the first energy storage module 11 and the second energy storage module 12 are used together to try to start the second head B. At this time, the electric quantity detection unit 131 judges whether the energy of the two energy storage modules can start the second head B. If it can, the second head B is started by using the two energy storage modules, and then the first switch K0, the second switch K01 and the third switch K02 are closed, and the second head B is continuously run by using the power supply unit 101. If not, when the energy of the two energy storage modules is used up, the first switch K0, the second switch K01 and the third switch K02 are controlled to be closed, and the energy of the power supply unit 101 is used to supplement the energy of the second head B to achieve the technical effect of energy-saving start of the new head.

[0149] Figure 4 The flow chart of the head start-up method of the integrated compressor provided for the embodiments of the present application. It is applied to the control process of the head start-up circuit of the integrated compressor. According to Figure 4 The steps of the head start-up method of the integrated compressor provided by the diagram specifically include:

[0150] S401, when detecting that the first head is in an abnormal running state, obtaining an initial power supply mode of the current second head, and the initial power supply mode is determined by a switch module.

[0151] The abnormal running state mentioned here can be understood as an overheating fault state. The initial power supply mode mentioned here can be understood as the default power supply state when starting the second head, and the initial power supply state is maintained by adjusting the switch state through the switch module.

[0152] Further, during the process of supplying power to the first head through the commercial power module, when it is detected through the control module that the first head overheats, the running of the first head is stopped, the starting process of the second head is started, the switch state is changed through the switch module, and the initial power supply module is used to supply power to the second head in the initial state, so as to provide a reference basis for judging whether the initial power supply mode meets the power supply demand of the second head.

[0153] S402, judging whether the initial power supply mode meets the power supply demand of the second head, and determining the corresponding judgment result.

[0154] Further, the switch state is adjusted by using the switch module, the default initial power supply mode is selected to supply power to the second head, and it is judged whether the electric energy provided by the current default initial power supply mode is sufficient to start the second head, and the corresponding judgment result is obtained through the judgment, so as to provide a basis for adjusting the switch module in the next step.

[0155] S403, determining the power supply strategy of the second head based on the judgment result.

[0156] The power supply strategy mentioned here can be understood as a strategy for selecting one or a combination of the first power supply module, the second power supply module, or the commercial power module to supply power to the second head.

[0157] Further, according to the judgment result, it is determined whether the power provided by the current power supply mode meets the demand for starting the second handpiece, and when the demand is met, a corresponding power supply strategy is generated, and when the current power supply demand of the second handpiece is not met, another power supply strategy is generated.

[0158] S404, based on the power supply strategy, performing power supply control on the second handpiece.

[0159] Further, according to the power supply strategy, when the current power supply mode meets the power supply demand of the second handpiece, the current power supply mode is maintained to start the second handpiece. When the current power supply mode cannot meet the power supply demand of the second handpiece, the switching state is adjusted by the switching module, the power supply module is selected to increase the starting voltage, and the purpose of starting the second handpiece is achieved, thereby realizing the technical effect of energy-saving start.

[0160] Figure 5 Another integrated-compressor handpiece starting method flowchart provided by the embodiment of the application. Figure 5 Based on the above embodiment, according to Figure 5 The provided diagram, the steps of the integrated-compressor handpiece starting method specifically include:

[0161] S501, when the first handpiece is in an overheating running state, controlling the first handpiece to stop running and performing energy storage control on the first energy storage module.

[0162] S502, when the first handpiece stops running, performing energy storage control on the second energy storage module.

[0163] S503, taking the single-energy power supply mode corresponding to the second energy storage module as the initial power supply mode of the second handpiece.

[0164] The initial power supply mode is determined by the switching module. The single-energy power supply mode mentioned here can be understood as power supply by one power supply module.

[0165] Further, when the current commercial power module is used to supply power to the first handpiece, the heat energy generated by the running of the first handpiece is converted into electric energy by the thermoelectric effect and stored in the first energy storage module. When the control module detects that the first handpiece has an overheating phenomenon, the commercial power module stops supplying power, the first handpiece stops running, and the mechanical energy generated by the inertial running of the first handpiece is converted into electric energy and stored in the second energy storage module. And through the switching module, the switching state is adjusted, so that the second energy storage module is used to supply power by default when starting the second handpiece initially.

[0166] S504, when the single-energy power supply mode meets the power supply demand of the second handpiece, a corresponding first judgment result is obtained.

[0167] S505, when the single-energy power supply mode does not meet the power supply requirement of the second handpiece, determining whether the dual-energy power supply mode meets the power supply requirement of the second handpiece.

[0168] S506, when the dual-energy power supply mode meets the power supply requirement, obtaining a corresponding second determination result.

[0169] S507, when the dual-energy power supply mode does not meet the power supply requirement, determining whether the multi-energy power supply mode meets the power supply requirement of the second handpiece.

[0170] S508, when the multi-energy power supply mode meets the power supply requirement, obtaining a corresponding third determination result.

[0171] The dual-energy power supply mode mentioned here can be understood as a process of selecting two power supply modules to start power supply. The dual-energy power supply mode mentioned here can be understood as a process of selecting multiple power supply modules to start power supply together.

[0172] Further, by determining whether the current power supply mode can meet the power supply requirement of the second handpiece, different power supply modules can be selected for the second handpiece by adjusting the switch state of the switch module. When the second energy storage module is selected to supply power to the second handpiece, if the current second energy storage module can start the second handpiece, the result that the single-energy power supply mode meets the power supply requirement of the second handpiece is taken as the first determination result. When one kind of power supply module cannot meet the power requirement of starting the second handpiece, the switch state of the switch module is adjusted, and it is determined whether two power supply modules can achieve the purpose of starting the second handpiece. When the dual-energy power supply mode can meet the starting requirement of the second handpiece, the current determination result is taken as the second determination result. When the dual-energy power supply mode cannot start the second handpiece, it is determined whether the multi-energy power supply mode can meet the power supply requirement by adjusting the switch state of the switch module. When the multi-energy power supply mode can start the second handpiece, a third determination result is obtained.

[0173] S509, when the determination result is the first determination result, determining that the power supply strategy corresponding to the second handpiece is the first power supply strategy.

[0174] S510, when the determination result is the second determination result, determining that the power supply strategy corresponding to the second handpiece is the second power supply strategy.

[0175] S511, when the determination result is the third determination result, determining that the power supply strategy corresponding to the second handpiece is the third power supply strategy.

[0176] S512, when the power supply strategy is the first power supply strategy, controlling the first switch and the third switch to be in an open state, and controlling the second switch to be in a closed state, so as to supply power to the second handpiece by the second energy storage module.

[0177] S513, when the power supply strategy is the second power supply strategy, controlling the first switch, the second switch and the third switch to be in an open state, and supplying power to the second handpiece through the first energy storage module and the second energy storage module.

[0178] S514, when the power supply strategy is the third power supply strategy, controlling the first switch to remain in a closed state, and controlling the second switch and the third switch to be in an open state, and supplying power to the second handpiece through the first energy storage module, the second energy storage module and the commercial power unit.

[0179] Further, different power supply strategies are generated according to different judgment results. When the single-energy power supply mode meets the starting demand of the second handpiece, the first switch and the third switch are controlled to be in an open state, and the second switch is in a closed state, and the second handpiece is supplied with power by the second energy storage module; when the dual-energy power supply mode meets the starting demand of the second handpiece, the first switch, the second switch and the third switch are adjusted to be in an open state, and the first energy storage module and the second energy storage module are used to supply power to the second handpiece; when the multi-energy power supply mode meets the starting demand of the second handpiece, the first switch is adjusted to remain in a closed state, and the second switch and the third switch are in an open state, and the first energy storage module, the second energy storage module and the commercial power unit are used to supply power to the second handpiece, thereby achieving the technical effect of selecting appropriate power supply energy to start the handpiece and reducing the power loss of directly using commercial power supply.

[0196] The control end of the first transistor Q1 is connected to the first output end of the detection control module 100 as the first input end of the single-energy starting module 200, the first end of the first transistor Q1 is connected with one end of the first resistor R1 and one end of the second resistor R2, and the second end of the first transistor Q1 is respectively connected with the other end of the second resistor R2, one end of the third resistor R3 and the positive input end of the first comparator U1.

[0205] Here, the first relay in this application is equivalent to Figure 2 The third switch K02 in Figure 7 The single energy storage unit in this application is equivalent to Figure 2 The second energy storage module in

[0206] Further, according to the internal structure of the single energy starting module, when the detection control module 100 detects that the running head is overheated, a new head is started. When the temperature signal reaches the set value, the single energy starting module 200 is first selected to execute the operation of starting a new head. The single energy starting module realizes the purpose of starting a new head by using one second energy storage module. The specific control process is as follows:

[0207] If the temperature is too high, a high level is output by the controller 132 to drive the first transistor Q1 to conduct, so that the second resistor R2 is short-circuited. A larger positive voltage V1+ is obtained at the positive input end of the first comparator U1, which represents the minimum energy threshold for starting a new head. The current energy signal V1- output by the controller 132 is transmitted to the reverse input end of the first comparator U1, and if the current energy is insufficient to start a new head (such as Figure 2When the current power is enough to start the new head, the power threshold V1 of the new head is less than the current power V1-, the first comparator U1 outputs a negative voltage signal, the second transistor Q2 is not conductive, so that the internal coil of the first relay K1 does not produce excitation, the internal first switch of the first relay K1 keeps the normally closed state, and the internal second switch of the first relay K1 keeps the closed state, and the second power supply module is started at this time.

[0216] The second relay mentioned here plays the same role in this application as Figure 2 The second switch K01 in Figure 7 The role of the dual energy storage unit in this application is equivalent to Figure 2 The second energy storage module and the first energy storage module.

[0217] Furthermore, if the single-energy startup module 200 fails to start the new handpiece, the dual-energy startup module 300 is selected to start the new handpiece by detecting the temperature signal and power signal output by the control module 100. The dual-energy startup module achieves the purpose of starting the new handpiece by utilizing two energy storage modules. The specific control process is as follows:

[0218] Since the first relay K1 inside the single-energy starting module 200 is closed, the controller 132 can transmit the over-temperature signal to the control terminal of the third transistor Q3. The controller 132 outputs a positive over-temperature signal to drive the third transistor Q3 to turn on, and at the same time, the fifth resistor R5 is short-circuited. A large positive voltage V2+ will be obtained at the positive input terminal of the second comparator U2. This positive voltage represents the minimum power threshold for starting a new handpiece. The controller 132 outputs the current power signal V2- to the reverse input terminal of the second comparator U2. If the current power is not enough to start a new handpiece (such as Figure 2The second head B in the first head A, so the power threshold V1+ of the new head is greater than the current power V1- at this time, the second comparator U2 outputs a positive voltage signal, driving the fourth transistor Q4 to turn on, so that the internal coil of the connected second relay K2 is excited, so that the internal first switch of the second relay K2 remains in an open state, while controlling the internal second switch of the second relay K1 to remain closed, controlling the second energy storage module 12 and the first energy storage module 11 to access the power supply system, and controlling the energy storage module 1 and the energy storage module 2 to access. If the current power is sufficient to start the new head, the power threshold V2 of the new head is less than the current power V2- at this time, the second comparator U2 outputs a negative voltage signal, the fourth transistor Q4 is not turned on, so that the internal coil of the second relay K2 is not excited, the internal first switch of the second relay K2 remains in a normally closed state, and the internal second switch of the second relay K2 remains in a closed state. At this time, the first power supply module and the second power supply module are started to supply power.

[0219] According to Figure 7 The provided diagram, the multi-energy starting module in the integrated compressor head starting system includes: a fifth transistor Q5, a sixth transistor Q6, a third comparator U3, a third relay K3, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, and a multi-energy storage unit 410.

[0228] Furthermore, if the dual-energy startup module 300 fails to start the new handpiece, the multi-energy startup module 400 is selected to start the new handpiece by detecting the temperature signal and power signal output by the control module 100. The multi-energy startup module achieves the goal of using more than three energy storage modules to start the new handpiece. The specific control process is as follows:

[0229] Since the second relay K2 in the dual-energy startup module 300 is closed, the controller can transmit the over-temperature signal to the fifth transistor Q5. The controller 132 outputs a positive over-temperature signal to drive the fifth transistor Q5 to conduct, causing the eighth resistor R8 to short-circuit. A large positive voltage V3+ is obtained at the positive input terminal of the third comparator U3. This positive voltage represents the minimum power threshold for starting a new handpiece. The controller 132 outputs the current power signal V3- to the positive input terminal of the third comparator U3. If the current power is insufficient to start a new handpiece (e.g., Figure 2 The second handpiece B in the figure), so the power threshold V3+ for starting the new handpiece is greater than the current power V3-, the third comparator U3 outputs a positive voltage signal, drives the sixth transistor Q6 to turn on, and the internal coil of the third relay K3 is excited, so that the first switch inside the third relay K3 remains in the open state, and the second switch inside the third relay K3 remains in the closed state, controlling Figure 2 The first energy storage module 11, the second energy storage module 12, and the mains unit 101 are connected. If the current power is sufficient to start the new handpiece, and the power threshold V3 of the new handpiece is less than the current power V3-, the third comparator U3 outputs a negative voltage signal, causing the sixth transistor Q6 to be non-conductive, the internal coil of the third relay K3 to be non-excited, the first switch inside the third relay K3 to remain in a normally closed state, and the second switch inside the third relay K3 to remain in a closed state. At this time, power supply is started through the first power supply module 11, the second power supply module 12, and the mains unit 101.

[0233] Further, the detection control module detects the temperature and electric quantity of the head currently running in the compressor. It is determined whether the current head has an overheating phenomenon, and reference data is provided for the next step of starting a new head.

[0238] Further, according to the power supply strategy, when the single-energy starting module reaches the starting voltage of the new head, the current power supply mode is maintained to start the new head. When the single-energy starting module cannot meet the starting of the new head, the double-energy starting module is selected by the detection control module outputting the control signal, it is determined whether the double-energy starting module reaches the starting voltage of the new head, the current double-energy starting module is maintained when the starting voltage is met, and the multi-energy starting module is turned on by the control signal when the double-energy starting module cannot reach the starting voltage of the new head.

[0244] In combination Figure 7 The temperature and electric quantity of the running head are detected by the temperature sensor and the electric quantity sensor to obtain corresponding electric quantity signals and temperature signals. When the temperature signal is detected to be too high, exceeding the set temperature threshold, the single-energy starting module is started, the conduction state of the first transistor and the first comparator is determined, the conduction state of the first relay is determined, and the power supply module for starting the new head can be determined according to the conduction state of the first relay.

[0259] According to the conductive state of the first relay, the second relay and the third relay, determine the power supply module required to start the new machine head. When the first relay is in the open state, it indicates that the detected power exceeds the set value, which means that the current single-energy starting module meets the starting requirement. By controlling the first relay to be open, the internal first switch is in the normally closed state, and the internal second switch is in the open state, the single-energy power supply module is used to supply power to the second machine head, that is, the second energy storage module is used for power supply. When the first relay is in the conductive state and the second relay is in the open state, it indicates that the detected power in the double-energy starting module meets the power supply requirement.

When the first relay and the second relay both remain in the conductive state, and the third relay remains in the open state, it indicates that the detected power in the multi-energy starting module exceeds the high threshold voltage, which means that the current multi-energy starting module meets the starting requirement. By controlling the third relay to be open, the internal first switch is in the normally closed state, and the multi-energy power supply module is used to supply power to the second machine head.
