They are used in some industries with high requirements for uninterrupted power supply and limited space. When moving from workstation A to workstation B, the power supply will be disconnected. At this time, the power stored in the supercapacitor of the device needs to be discharged to temporarily power the high-precision sensor. The power supply duration can be adjusted until power input is available, at which point the capacitor is disconnected to discharge and continue to store power. It is compatible with different types of automated uninterrupted power supply production, testing and handling, and has a certain improvement on automated process control.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention provides a wide-temperature industrial mobile energy storage power supply, which includes a power supply shell, which is a hollow cavity structure. A circuit board is installed inside the cavity, and an energy storage power supply circuit is installed on the circuit board. The energy storage power supply circuit includes at least a power protection circuit, a control circuit, a filter circuit, a voltage divider circuit, and a voltage regulator circuit. The overall structure is simple and the design is reasonable. In automated production where there is a large temperature difference and the space is compact and the power supply needs to be moved without interruption, the high-precision sensor needs to work continuously during the process of moving from workstation A to workstation B. During the movement, the external power supply will be disconnected, and the wide-temperature mobile energy storage power supply of the main body will start to supply power, allowing the high-precision sensor to continue working and smoothly reach workstation B. The discharge time of the wide-temperature mobile energy storage power supply can be adjusted to 60-100 seconds or even longer. When the power supply is at workstation A, the internal circuit of the wide-temperature mobile energy storage power supply flows in through the fuse F1 to ensure that the current in the circuit is normal. When the current is too large, the fuse F1 will melt its own circuit to cut off the power supply, thereby protecting other components. The circuit is damaged, and the transient voltage suppressor diode (TVS) protects the electronic circuit from damage caused by transient high voltage surges, power surges, and transient voltage changes. When the voltage in the circuit exceeds the rated value of 13V, the TVS diode will quickly conduct; when the voltage exceeds the rated value, it will guide the excessive voltage to the ground terminal, thus stabilizing the voltage within a safe range. The pre-filter circuit mainly functions as a current limiter, voltage divider, or protection circuit. Under the action of the Schottky SS14 diode, the current conducts in the forward direction and is cut off in the reverse direction, achieving unidirectional conduction. The voltage is then supplied by the precision adjustable parallel regulator U8. The supercapacitor controls the upper limit of the compensation voltage. The 0.1uF capacitor is an input filter capacitor used to filter out high-frequency noise in the voltage and protect the five series-connected filter circuits from reverse voltage damage. The N-channel MOSFET controls the circuit's on / off state, transferring and blocking current. The dual PNP Darlington transistor U14 increases the current gain to drive the load. Resistors R1 and R2 limit current and provide protection, ensuring that the dual PNP Darlington transistor U14 operates within a safe range, directing current to the ground terminal and stabilizing the base voltage.The current flows through the precision adjustable parallel regulator U22, where a voltage divider network consisting of resistors R129, R128, R127, and R126 provides power to pins 2 and 3. As current enters, it can be finely adjusted using resistors R128 and R127. When the voltage at pin 2 of the precision adjustable parallel regulator U22 is less than 2.5V, during normal power supply, current flows in from pin C and out from pin A, passing through resistor R4 to the VIN and SHDN pins of the power conversion chip U1. First, the SHDN pin is checked to confirm a high level before VIN can input current. Feedback is received from the FB pin of power conversion chip U1 via resistors R5 and R6. Capacitor C3 filters out some interference for power conversion chip U1, while capacitor C2 acts as a voltage regulator to smooth out voltage fluctuations. The on / off time of the SW pin is then determined to stabilize the output voltage. Diode D2 following the SW pin allows only unidirectional conduction to prevent reverse current from damaging power conversion chip U1, thus supplying power to the high-precision sensor. When station A moves to station B... During the process, the external power supply is disconnected, and the five supercapacitors begin to discharge. The discharge flows through resistor R4 to the VIN and SHDN pins of the power conversion chip U1. First, the SHDN pin is confirmed to be high before VIN can input current. The current is fed back from the FB pin of the power conversion chip U1 through resistors R5 and R6. Capacitor C3 eliminates some interference for the power conversion chip U1, while capacitor C2 acts as a "voltage regulator" to filter out the fluctuating voltage and determine the on / off time of the SW pin to stabilize the output voltage. The diode D2 after the SW pin can only conduct unidirectionally to prevent reverse current from damaging the power conversion chip U1 and supplying power to the high-precision sensor. This improves the situation in mobile automated production without power interruption, where frequent changes in workstations can cause power outages for the high-precision sensor. It also ensures stable normal operation in production environments ranging from -20°C to 70°C, overcoming the influence of temperature and improving production efficiency. It allows the high-precision sensor to operate stably under extreme temperatures for extended periods with a mobile energy storage power supply, enabling it to stand out in automated production.
