Technical Field

[0001] The utility model is an elevator UPS device based on CAN communication, belonging to the technical field of elevators. Background Art

[0002] With the continuous development and progress of society and the increasing improvement of people's material and cultural life, high-rise buildings are emerging in cities, and elevators are widely used in these high-rise buildings.

[0003] Existing elevator UPSs use digital inputs and outputs to exchange information between the elevator UPS and the mainboard, which presents numerous inconveniences. CAN technology is used to exchange data between the elevator UPS and the mainboard, and a 4G IoT module is used to provide early warning of EUPS failures. CAN technology is also used to discharge the battery during elevator idle time. Long-term battery aging and reduced service life can occur with elevator UPSs without discharging. A CAN-based elevator UPS device is urgently needed to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an elevator UPS device based on CAN communication to solve the problems raised in the above background technology. The utility model realizes the automatic discharge of the elevator UPS battery to maintain the battery life, realizes automatic maintenance of the elevator UPS, and realizes the early warning function of low battery power through CAN communication.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solution: a CAN communication-based elevator UPS device, including an elevator mainboard, a voice broadcast, a car display, a 4G Internet of Things module, an external display, an elevator UPS and an elevator inverter. The elevator UPS transmits the elevator mainboard, voice broadcast, car display, 4G Internet of Things module, and external display via CAN data. The elevator UPS is also interconnected with the elevator mainboard, voice broadcast, car display, 4G Internet of Things module, and external display via a CAN bus. The elevator UPS is connected to the elevator inverter via a wire, and the elevator inverter is bidirectionally connected to the elevator mainboard. The elevator inverter receives elevator operation status data in real time.

[0006] Furthermore, CAN data exchange enables elevator UPS control.

[0007] Furthermore, CAN communication and 4G Internet of Things enable remote monitoring of elevator UPS, remote monitoring of elevator UPS battery power information, and remote warning of low power.

[0008] The UPS has automatic discharge and self-maintenance technology, as well as voice reminders for discharge and low power.

[0009] Furthermore, the elevator inverter has a load memory function module, which determines the load difference between the elevator car and the counterweight according to the current during operation, and outputs a direction signal to the elevator main board in an emergency to make the elevator reach the nearest level.

[0010] Beneficial effects of the present invention: The present invention is an elevator UPS device based on CAN communication, which realizes real-time data such as battery power through CAN data transmission, and then uploads the elevator UPS battery power to the server in real time through 4G Internet of Things technology, thus realizing remote monitoring of the elevator UPS. At the same time, for elevator UPS that does not discharge for a long time, data exchange is realized with the mainboard through CAN communication to realize emergency operation of the elevator UPS once during idle time, thereby realizing automatic discharge of the elevator UPS battery, maintaining battery life, and realizing automatic maintenance of the elevator UPS. The low battery early warning function is realized through CAN communication. And the low battery warning of the UPS is realized through voice broadcast. Before discharging, a discharge reminder is realized by voice broadcast, and a text discharge reminder is displayed on the display board. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Other features, objects and advantages of the present invention will become more apparent from the detailed description of the non-limiting embodiments with reference to the following drawings:

[0013] Figure 2 This is a schematic diagram of the control principle of the elevator UPS device of a traditional elevator. DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0015] See also Figure 1-Figure 2 The utility model provides a technical solution: an elevator UPS device based on CAN communication, including an elevator mainboard, a voice broadcast, a car display, a 4G Internet of Things module, an external display, an elevator UPS and an elevator inverter. The elevator UPS transmits the elevator mainboard, voice broadcast, car display, 4G Internet of Things module and external display through CAN data. The elevator UPS is also interconnected with the elevator mainboard, voice broadcast, car display, 4G Internet of Things module and external display through the CAN bus. The elevator UPS is connected to the elevator inverter through a wire. The elevator inverter is bidirectionally connected to the elevator mainboard. The elevator inverter receives the status data of the elevator operation in real time.

[0016] CAN data exchange enables elevator UPS control; CAN communication and 4G IoT enable remote monitoring of elevator UPS, including battery level information and low-battery remote warning. The UPS has automatic discharge and self-maintenance technology, as well as voice reminders for discharge and low-battery conditions.

[0017] The elevator inverter is equipped with a load memory function module. It determines the load difference between the elevator car and the counterweight based on the current during operation. In an emergency, it outputs a direction signal to the elevator main board to make the elevator reach the nearest level.

[0018] As the first embodiment of the present invention: Figure 1 As shown, the principle diagram of the present invention is different from the traditional principle diagram ( Figure 2 ) Compared with the traditional one, the mainboard and the elevator UPS are connected through CAN. The traditional one is connected through the switch input point. The rescue completion signal is output through the mainboard Y0 to the elevator UPS. The elevator UPS transmits the elevator UPS emergency operation, fault and low power start signals to the elevator mainboard through outputs T1, T2 and T3 respectively. Figure 1 As shown, a 4G Internet of Things module is added to the electrical schematic diagram of the utility model, which is used to transmit early warning signals such as elevator UPS failure and insufficient battery voltage to the management platform, and at the same time send early warning signals such as low battery power to maintenance personnel and management personnel through text messages and other means.

[0019] like Figure 1 As shown, the present invention uses an elevator UPS to calculate the cumulative undischarged time, for example, six months. When the accumulated time reaches five months, it sends a discharge request signal and sets the discharge request bit to 1. Upon receiving the signal, the mainboard invokes the discharge subroutine. Once the elevator meets discharge conditions, the mainboard, depending on whether it is nighttime or idle, sends a discharge permission signal via CAN and resets the discharge request bit. Upon receiving the discharge permission signal, the elevator UPS invokes the discharge subroutine, disconnects the mains power output, converts DC power to AC power, initiates the discharge operation, and sets the discharge flag bit to 1. Upon receiving the discharge flag bit as 1, the mainboard immediately controls the elevator to operate at a low speed, and displays a soothing voice message indicating that the discharge operation is about to begin. The elevator announces that the elevator UPS is about to enter the discharge operation mode. The call panel and the in-car display panel display "System is in the process of performing the elevator UPS discharge operation." At this point, the elevator blocks all incoming call commands. The elevator then initiates a power outage emergency leveling operation, slowly running to the nearest floor and stopping. A voice announcement announces the end of the elevator UPS discharge operation, and the in-car display panel displays "Elevator UPS discharge operation completed."

[0020] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
