Description

Technical Field

[0001] This utility model relates to the field of elevator rescue equipment technology, specifically a split-type ARD battery status detection device. Background Technology

[0002] ARD is an automatic rescue device for elevators during power outages. It can be automatically activated when the mains power is interrupted through a built-in energy storage device (such as a battery). It supplies emergency power to the elevator control system, drives the car to level the floor and opens the car door. ARD solves the safety hazard of passengers being trapped due to sudden power outages and effectively avoids the harm to passengers' personal safety and psychology caused by being trapped in a confined space.

[0003] In ARD (Automatic Rescue Equipment), the battery pack serves as an energy storage and release carrier. It not only undertakes the energy storage function of emergency power supply, but also serves as the power output center of the entire rescue device. Its performance directly determines key indicators such as system response speed and continuous rescue duration. However, as an electrochemical energy storage element, the health status of the battery will dynamically deteriorate with factors such as the usage environment and charging and discharging frequency, so the battery status needs to be tested.

[0004] Currently, the method for detecting the status of ARD batteries is usually that maintenance personnel approach the ARD and disassemble its cabinet to directly test the battery with a battery tester. However, since maintenance personnel directly contact the positive and negative terminals of the battery without disconnecting the power, there is a risk of electric shock due to tool slippage or accidental contact with live parts. When manually clamping the test clip, poor contact or operational errors may cause instantaneous arc discharge, threatening personal safety. Therefore, we need to propose a split-type ARD battery status detection device to solve the above-mentioned problems and improve the safety of battery testing. Utility Model Content

[0005] The purpose of this invention is to provide a split-type ARD battery status detection device. By using a split logic control component and a status detection component, and connecting the logic control component and the status detection component through plug-in and plug-in connections, maintenance personnel are freed from frequently disassembling and assembling the ARD cabinet, thereby improving the safety of battery detection and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a split-type ARD battery status detection device, including a logic control component deployed in an elevator control cabinet or an elevator emergency operation panel and a status detection component that can be carried independently. The status detection component includes a battery status detector and a cable connected to the battery status detector. The other end of the cable is fixed with a plug. The logic control component is provided with a plug for inserting the plug.

[0007] Preferably, the logic control component includes a detachable control housing, on which a detection switch, an audible and visual alarm, and a logic relay are respectively installed. The plug, the detection switch, and the audible and visual alarm are all located on the same side of the control housing, and the logic relay is located on the side of the control housing adjacent to the plug.

[0008] Preferably, the control housing includes a bottom shell and a cover plate, the detection switch and the audible and visual alarm are both located on the cover plate, the cover plate is connected to the bottom shell by screws, and the cover plate is provided with an operating instruction label, and the upper end of the bottom shell is provided with mounting holes.

[0009] Preferably, the logic control component further includes a main control chip connected to the three-phase power supply. The main control chip is connected to the ARD battery, the plug, and the audible and visual alarm via logic relays. The detection switch is connected to the logic relays to control the connection and disconnection of the charging and discharging circuits of the status detection component, the audible and visual alarm, and the ARD battery.

[0010] Preferably, the detection switch is configured as a rocker switch, and a protection diode is connected to the logic relay contact connected to the detection switch.

[0011] Preferably, when the detection switch is closed, the logic relay contact connected to the status detection component is disconnected, and the audible and visual alarm sounds simultaneously. When the detection switch is open, the logic relay contact connected to the status detection component is closed, and the audible and visual alarm stops sounding.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a split-type ARD battery status detection device, including a logic control component deployed in an elevator control cabinet or elevator emergency operation panel and a status detection component that can be carried independently. The status detection component includes a battery status detector 8 and a cable connected to the battery status detector 8. The other end of the cable is fixed with a plug 9. The logic control component is provided with a plug 5 for the plug 9 to be inserted.

[0024] By using a separate logic control component and a status detection component, and connecting the logic control component and the status detection component through plug 9 and plug 5, non-contact testing with the ARD is achieved, replacing the manual clamping of the test fixture by maintenance personnel. This frees maintenance personnel from frequently disassembling and assembling the cabinet door when approaching the ARD, thus improving the safety of battery testing.

[0025] The logic control component includes a detachable control housing, on which a detection switch 3, an audible and visual alarm 4, and a logic relay 7 are respectively installed. The plug 5, the detection switch 3, and the audible and visual alarm 4 are all located on the same side of the control housing. The logic relay 7 is located on the side of the control housing adjacent to the plug 5. The detection switch 3, the audible and visual alarm 4, and the plug 9 are embedded in the cover plate 2 to facilitate observation of the alarm emitted by the audible and visual alarm 4 from outside the control housing, manual opening and closing of the detection switch 3, and convenient insertion and removal of the plug 5 and the plug 9.

[0026] The control housing includes a bottom shell 1 and a cover plate 2. The detection switch 3 and the audible and visual alarm 4 are both located on the cover plate 2. The cover plate 2 is connected to the bottom shell 1 by screws, and an operation instruction label 6 is provided on the cover plate 2. The operation instruction label 6 is a silver-plated label indicating the operation instructions for ARD battery status detection. The upper end of the bottom shell 1 is provided with mounting holes, such as... Figure 1 The mounting hole shown consists of a circular mounting part and an arc-shaped protrusion, with the protrusion communicating with the mounting part. When installed with the elevator control cabinet or elevator emergency operation panel, the mounting part and the protrusion provide a certain amount of movement space, allowing the mounting position of the base 1 to be finely adjusted by a certain distance. The logic relay 7 is connected to the base box by bolts. Whether the logic relay 7 is energized or not, it controls the connection and disconnection of the ARD battery status detection circuit, the audible and visual alarm 4 circuit, and the ARD battery charging and discharging circuit. The audible and visual alarm 4 operates at 24V. When maintenance personnel are performing inspection work, it issues audible and visual alarms to indicate risks and also prompts maintenance personnel to return the detection switch 3 to the off position after the inspection work is completed.

[0027] The logic control component also includes a main control chip connected to the three-phase power supply. The main control chip is connected to the ARD battery, plug 5, and audible / visual alarm 4 via logic relay 7. The detection switch 3 is connected to the logic relay 7, controlling the connection and disconnection of the status detection component, the audible / visual alarm 4, and the charging / discharging circuit of the ARD battery. Figure 4 As shown, the main control chip is represented by UPS. The upper end of the main control chip is connected to the three-phase power supply L1, L2 and L2. The positive terminal of the main control chip is connected to the 1-9 contacts of logic relay 7. The 9th contact of logic relay 7 is connected to the ARD battery. One end of the ARD battery is connected to the power display. One end of the power display is connected to the 10-2 contact of logic relay 7. The 2nd contact of logic relay 7 is connected to the negative terminal of the main control chip. At the same time, the 9-5 contacts and the 10-6 contacts of logic relay 7 are connected to plug 9. When plug 5 is plugged into plug 9, the battery status detector 8 communicates with the main control chip.

[0028] The detection switch 3 is configured as a rocker switch, and a protection diode is connected to the contact pin of the logic relay 7 connected to the detection switch 3, such as... Figure 4As shown, the audible and visual alarm 4 is connected to the contact of the logic relay 711-7. The 7th pin of the logic relay 7 is connected to one end of the detection switch 3, and the other end of the detection switch 3 is connected to the normally closed contact of the logic relay 7. A protection diode is connected in parallel to the normally closed contact of the logic relay 7. The protection diode is a freewheeling diode, with its anode connected to the low-voltage side of the relay coil and its cathode connected to the high-voltage side (the polarity needs to be confirmed according to the actual circuit). When the coil is de-energized, the protection diode conducts, providing a low-impedance loop for the reverse current, clamping the voltage within a safe range, thereby eliminating the arc between the contacts, extending the relay life, and protecting the audible and visual alarm 4 and other circuits from high-voltage impacts, ensuring circuit stability and component reliability.

[0029] When the detection switch 3 is closed, the contact of the logic relay 7 connected to the status detection component is disconnected, ensuring that the discharge circuit of the ARD battery to the elevator system is disconnected during the battery status detection, avoiding the risk of equipment malfunction or electric shock to personnel caused by the test operation. At the same time, the audible and visual alarm 4 sounds an alarm, visually alerting maintenance personnel that the battery status detection mode is in progress. When the detection switch 3 is open, the contact of the logic relay 7 connected to the status detection component is closed, and the audible and visual alarm 4 stops sounding.

[0030] The plug 9 is configured as a snap-fit ​​connector or a slot-type connector. The plug 5 is matched with the plug 9. The snap-fit ​​connector provides a stable mechanical connection through a physical snap-fit ​​structure (such as the engagement of protrusions and grooves), effectively resisting vibration, impact or accidental pulling, reducing the risk of poor contact or disconnection, and supporting one-handed insertion and removal without additional tools, significantly shortening installation or maintenance time.

[0031] The slot-type connector ensures precise alignment of plug 5 and insert 9 through guide groove or keying design, reducing the possibility of mis-insertion and ensuring the stability of signal or power transmission. Tactile feedback (such as the "click" sound of a latch) assists in blind insertion, improving the convenience of connection. It also supports hot-swapping, facilitating the rapid upgrade or replacement of system modules and enhancing the scalability of the device.

[0032] like Figure 5 As shown, during battery status detection, detection switch 3 is in the closed state, logic relay 7 is energized, logic control component is closed, monitoring circuit is connected, and at this time, audible and visual alarm circuit is connected to alert maintenance personnel. The personnel monitor and record the battery status. When the logic control component is closed, the status detection component disconnects the emergency discharge circuit from the ARD battery to the elevator system.

[0033] When the battery status detection is completed, the detection switch 3 is turned off and in the closed state. The logic relay 7 is de-energized, the logic control component is disconnected from the status detector, the monitoring circuit is disconnected, and the audible and visual alarm circuit is also disconnected. At this time, the status detection component connects the ARD battery to the emergency discharge circuit of the elevator system.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
