Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a dual-power automatic switching monitoring data acquisition module power supply device and method. Background Art

[0002] Powering the data acquisition module refers to the process of providing the required electrical energy to the data acquisition module to ensure its normal operation. The data acquisition module is a device used to collect various physical quantities, electrical signals and other data. In order to ensure that the data acquisition module can stably and accurately collect and transmit data, reliable power supply is crucial. There are usually multiple power supply methods, including DC power supply, AC power supply and battery power supply. DC power supply has the characteristics of high stability and strong anti-interference ability, and can provide pure power for the module. AC power supply is suitable for occasions with mains access. The power adapter converts AC power into DC power suitable for the module to work. Battery power supply has the advantage of high flexibility and can be used in some mobile or remote scenarios without mains power, but the battery life and replacement cycle need to be considered. In addition, in order to prevent the influence of power supply fluctuations on the collected data, it is often equipped with voltage stabilization circuits, filtering circuits, etc. to ensure the stability and purity of the power supply.

[0003] At present, during the use of the existing monitoring data acquisition module power supply device, after 3 years of operation, the power module will gradually age, and the battery storage voltage will be less than 6V, which cannot reach the normal operating voltage of the acquisition module of 6V. The acquisition module will stop running and needs to be replaced in time to return to normal. If the power module battery ages on a large scale within the same period of time and cannot be replaced in time, the entire data acquisition system will be paralyzed, which will easily affect the normal use of the equipment.

[0041] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0042] The present invention proposes a dual power supply automatic switching monitoring data acquisition module power supply device, the following reference Figures 1 to 6 Provide detailed explanation.

[0043] A dual-power automatic switching monitoring data acquisition module power supply device includes a box 1, a power supply mechanism 3 is fixedly arranged inside the box 1, a control mechanism 2 is arranged outside the box 1, the power supply mechanism 3 includes an acquisition module 305 and a power module 304, and a conventional power supply line is arranged between the power module 304 and the acquisition module 305;

[0044] An emergency power supply assembly is provided in the box 1, and the emergency power supply assembly is electrically connected to the conventional power supply line through a wire. The emergency power supply assembly includes a first intelligent switch 301 for controlling the on and off of the circuit;

[0045] A detection component for detecting the voltage of the power module 304 is provided in the box 1;

[0046] The control mechanism 2 is electrically connected to the detection component and the first intelligent switch 301 or is wirelessly connected to the detection component.

[0047] The present invention detects the voltage of the power module 304 in real time through a detection component. When the power supply is lower than 6V or the power supply voltage is abnormal, causing the power module 304 to be unable to normally supply power to the acquisition module 305, the control mechanism 2 controls the first intelligent switch 301 to open. At this time, the emergency power supply component is put into use to directly supply power to the acquisition module 305, so that the acquisition module 305 can work normally when the power module 304 is in an abnormal working state.

[0048] In some embodiments, the acquisition module 305 includes an acquisition module 305 body for collecting data and an information transmission end for transmitting information. The emergency power supply component includes a backup power supply line connected to an external device. The backup power supply line can be directly connected to a 220V power supply or connected to other batteries. The backup power supply line is introduced from outside the box 1 into the box 1 and is electrically connected to a second small transformer 12. The voltage of the backup power supply line is changed to 7V after being transformed by the second small transformer 12. The second small transformer 12 is connected to a first connection connector 3021 through a 7V line. A normally-on line for powering the information transmission end and a normally-off line for powering the acquisition module 305 are drawn out from the first connection connector 3021. The normally-on line and the normally-off line are arranged in parallel, and the first intelligent switch 301 is arranged on the normally-off line for controlling the on and off of the normally-off line.

[0049] In some embodiments, the voltage within the always-on circuit is set to 7V, and the always-on circuit extends from the first connection connector 3021 to an information transmission terminal electrically connected to the data acquisition module 305. This ensures that the data acquisition module 305 can still transmit collected data to the control mechanism 2 normally during the period from when the power module 304 is powered off to when the control mechanism 2 controls the normally-off circuit, thereby avoiding data loss caused by a power outage of the power module 304.

[0050] In some embodiments, the normally-off circuit includes a second connection connector. A first small transformer 308 and a first intelligent switch 301 are disposed between the second connection connector and the first connection connector 3021. The normally-off circuit, extending from the first connection connector 3021, passes through the first intelligent switch 301, the first small transformer 308, and the second connection connector. A regular power supply circuit passes through the second connection connector and is separated into two independent circuits by the second connection connector. The normally-closed circuit is disconnected from the wire between the power module 304 and the second connection connector and is connected only to the line between the second module and the acquisition module 305.

[0051] After the normally-off line is transformed by the first small transformer 308, the voltage of the 7V line drawn from the first connector is changed to a voltage of 6V. Then, after the normally-off line is connected to the conventional power supply line, the normally-off line can directly power the acquisition module 305.

[0052] The conventional power supply line is divided into two independent lines by the second connection connector, and the two independent lines can be connected in series through the first connection connector 3021 under normal operation; the separate setting allows independent replacement of the damaged part when a certain section of the independent line is damaged.

[0053] When the detection component detects that the voltage of the power module 304 is lower than 6V, the control mechanism 2 controls the emergency power supply component to work, and the control mechanism 2 controls the first intelligent switch 301 to open. The backup power supply line connected to the external device directly supplies power to the data acquisition module 305 after the second transformer and the first transformer transform the voltage.

[0054] In some embodiments, the detection assembly includes a voltage sensor 206 for detecting the voltage of the power module 304. A second connection connector is provided with a plurality of conductive fastening bolts 307 for securing electrical wires. The contacts of the voltage sensor 206 are detachably electrically connected to the two conductive fastening bolts 307 of the second connection connector, and the voltage sensor 206 is electrically or wirelessly connected to the control mechanism 2. Because the voltage sensor 206 is directly in contact with the fixing bolts that secure the power supply circuit of the power module 304, that is, the voltage measured by the voltage sensor 206 is the same as the voltage at the output end of the power module 304, the voltage of the power module 304 can be detected by measuring the voltage of the second connection connector.

[0055] In some embodiments, in order to protect the first connection connector 3021 and the second connection connector, a protective cover 303 is provided on the first connection connector 3021 and the second connection connector, and a through hole 306 for inserting the contact of the voltage sensor 206 is provided on the protective cover 303 of the second connection connector, so as to facilitate the voltage sensor 206 to measure the voltage at the connection end of the power module 304 of the second connection connector.

[0056] In some embodiments, the mechanism includes a fixing plate 204 disposed within the housing 1 , the fixing plate 204 being parallel to the contact surface between the second connection connector and the voltage sensor 206 , one end of the fixing plate 204 being detachably fixedly connected to the voltage sensor 206 , and an end of the fixing plate 204 away from the voltage sensor 206 being slidably connected to the inner wall of the housing 1 ;

[0057] A screw 205 is provided on the inner wall of the box body 1 in a direction perpendicular to the fixed plate 204. The screw 205 passes through the fixed plate 204 and is threadedly connected to the fixed plate 204. A rotating block 13 is provided on the end of the screw 205 away from the inner wall of the box body 1, and multiple groups of anti-slip grooves 14 are provided on the rotating block 13 to facilitate the operation of the operator to control the screw 205.

[0058] A guide rod is provided in the box body 1 parallel to the screw rod 205 , and the guide rod is slidably connected to the fixing plate 204 .

[0059] When installing the voltage sensor 206, the staff first controls the screw 205 to drive the fixing plate 204 away from the second connection connector, then installs the voltage sensor 206 to the end of the fixing plate 204, and again controls the screw 205 to rotate in the opposite direction, so that the fixing plate 204 drives the voltage sensor 206 closer to the second connection connector, so that the contact of the voltage sensor 206 can be inserted into the through hole 306 of the protective cover 303 and stably contact with the conductive fixing bolt at the end of the power module 304 of the second connection connector.

[0060] In some embodiments, a T-shaped slider is provided at one end of the fixing plate 204 away from the voltage sensor 206, and a T-shaped slot is provided on the inner wall of the box body 1 to cooperate with the T-shaped slider. The provision of the T-shaped slot and the T-shaped slider can increase the degree of freedom, thereby making the fixing plate 204 more stable during movement.

[0061] In some embodiments, the emergency power supply component also includes a second intelligent switch 309 set on the power module 304, and the second small transformer 12 leads to a charging line, which is connected to the input end of the power module 304 through the second intelligent switch 309, and the second intelligent switch 309 is electrically or wirelessly connected to the control mechanism 2.

[0062] When the detection component detects that the voltage of the power module 304 is lower than 6V, the control mechanism 2 controls the emergency power supply component to work, and the control mechanism 2 synchronously controls the second intelligent switch 309 to open. The backup power supply line connected to the external device is transformed by the second transformer and then directly charges the power module 304 through the charging line.

[0063] In some embodiments, the control mechanism 2 includes a controller 201 , a wireless communication module 202 , and a warning light 203 ;

[0064] The controller 201 is electrically connected to the emergency power supply component, the detection component, the wireless communication module 202 and the warning light 203;

[0065] The controller 201 is configured to receive data information from the emergency power supply component and the detection component, and send an execution action signal to the wireless communication module 202 and the warning light 203;

[0066] The wireless communication module 202 is configured to transmit the data received by the controller 201 to the remote control center via wireless communication. The staff can monitor the status of the power module 304 in a timely manner through the remote control center and provide timely feedback to relevant personnel through various channels, further improving feedback efficiency.

[0067] The warning light 203 is configured to emit an alarm flash after receiving the alarm action signal sent by the controller 201. When the staff finds that the warning light 203 is flashing, the staff can promptly know that the power module 304 in the box 1 needs to be replaced due to aging or other reasons.

[0068] In some embodiments, to ensure the safety of the backup power supply line connected to the external device, an MCB is provided in the housing 1. After entering the housing 1, the backup power supply line first passes through the MCB before being connected to the second small transformer 12. Furthermore, a wire hole 10 is provided on the housing 1 for inserting the backup power supply line.

[0069] In some embodiments, in order to dissipate the heat generated by the components in the box 1, multiple groups of heat dissipation holes 9 are provided on the box 1 to prevent the heat generated by the components from accumulating and causing heat loss to the various components in the box 1.

[0070] In some embodiments, a storage frame 8 is provided on the outer wall of the box body 1 for storing some small tools or spare parts related to the power supply device.

[0071] In some embodiments, a side wall of the box body 1 facing away from the power supply mechanism 3 is set as a box door 4, one side of the box door 4 is hinged to the box body 1, and a lock body for locking the box door 4 is set on the side of the box body away from the hinged end, and a handle 5 is set on the side of the box door 4 close to the lock body, and the staff can pull open the box door 4 through the handle 5.

[0072] In some embodiments, a plurality of positioning blocks 6 for installing the box 1 are provided above the box 1 , and each positioning block 6 is provided with a positioning hole 7 . The staff can hang the box 1 as a whole in a scene with a protrusion through the positioning blocks 6 .

[0073] The present invention also provides a method for using a dual power supply automatic switching monitoring data acquisition module power supply device, referring to Figure 7 , including the following steps:

[0074] S1. Install the emergency power supply component and the detection component. The detection component detects the voltage of the power module 304 in real time and feeds back the monitoring results to the control mechanism 2 in real time.

[0075] S2. When the detection component detects that the voltage of the power module 304 is lower than 6V, the control mechanism 2 controls the emergency power supply component to operate, and the control mechanism 2 controls the first intelligent switch 301 to open. The backup power supply line connected to the external device is transformed by the second transformer and the first transformer to directly supply power to the data acquisition module 305;

[0076] S3. When the detection component detects that the voltage of the power module 304 is lower than 6V, the control mechanism 2 controls the emergency power supply component to operate, and the control mechanism 2 simultaneously controls the second intelligent switch 309 to open. The backup power supply line connected to the external device is transformed by the second transformer and then directly charges the power module 304 through the charging line;

[0077] S4. When the detection component detects that the voltage of the power module 304 has recovered to 6V, the control mechanism 2 receives the information from the detection component and controls the first intelligent switch 301 and the second intelligent switch 309 to be disconnected, so that the power module 304 is restored to directly power the data acquisition module 305.
