Embodiment 1

[0070] The servo motor driver provided in this embodiment can be applied to various gate systems, see figure 1 As shown, it includes but is not limited to a microprocessor 11, a communication unit 12 connected to the microprocessor 11, a brake circuit 17, an encoder circuit 14, and a power drive circuit 15; wherein:

[0071] The communication unit 12 is used for sending the first information from outside to the microprocessor 11, and / or for sending the third information sent by the microprocessor to an external device. In this embodiment, the communication unit 12 can adopt various communication links that can realize the information interaction between the microprocessor 11 inside the servo motor driver and the outside, for example, it can include but not limited to I / O communication unit, RS485 communication unit, RS232 The communication unit is at least one of CAN (Controller Area Network, Controller Area Network) bus communication units. In this embodiment, the first info...

Embodiment 2

[0093] At present, the communication unit used to communicate with the outside on the servo motor driver on the market is relatively single, which is not conducive to improving the compatibility of the servo motor driver and is also not conducive to user selection. In this example, figure 1 The illustrated communication unit 12 includes at least two types of communication units, such as but not limited to at least two of a serial interface communication unit, a CAN bus communication unit, and an I / O (input / output) communication unit, such as an example Including the above three communication units. It is worth noting that the three communication units listed here are just an example, and are not limited to the above three communication units. In practical applications, designers can also flexibly set them according to specific scene requirements. In this embodiment, the serial interface communication unit may include at least one of an RS232 communication unit and an RS485 co...

Embodiment 3

[0102] One of the current performance requirements for gates is the synchronous control of the left and right gates. At present, the left and right doors of the gate are independently controlled by two independent motor drive controllers. Therefore, in the process of controlling the opening and closing of the gates, there will often be a problem that the left and right gates are not synchronized. , resulting in security risks and low user experience satisfaction.

[0103] Therefore, in an example of this embodiment, the servo motor driver may also include a master-slave communication unit 13 connected to a microprocessor, for example, see Figure 5 As shown, the servo motor driver can be connected to the paired servo motor driver (hereinafter referred to as the paired servo motor driver) through the master-slave communication unit 13, for receiving the fourth information from the paired servo motor driver and passing it to the microprocessor 11, And / or for sending the fifth inf...

Abstract

The invention provides a servo motor driver, device and system for a gate and gate equipment. The servo motor driver comprises a microprocessor, an encoder circuit, a communication unit, a power driving circuit and a band-type brake circuit, wherein the encoder circuit, the communication unit, the power driving circuit and the band-type brake circuit are connected with the microprocessor. The communication unit is used for sending the received first information to the microprocessor. The encoder circuit is connected with the encoder and used for transmitting second information sent by the encoder to the microprocessor. The microprocessor is used for sending a band-type brake control signal to the band-type brake circuit to start the band-type brake circuit to achieve band-type brake and controlling the servo motor through the power drive circuit to drive the gate to execute corresponding actions according to the first information or the second information. The motor driver provided bythe invention is provided with the band-type brake circuit, and the band-type brake circuit is started through the band-type brake control signal to realize band-type brake when needed, so that the potential safety hazard that the gate equipment is forcibly opened in a door closing state can be avoided, and the safety and the intelligence of the gate equipment and the satisfaction of user experience are improved.

Description

technical field [0001] The invention relates to the field of gate control, in particular to a servo motor driver, device, system and gate equipment for gates. Background technique [0002] The gate machine described in this article is a channel blocking device (channel management equipment), which is used to manage the flow of people and regulate pedestrian access. Other names of turnstiles include but are not limited to swing turnstiles, wing turnstiles, translational turnstiles, etc. [0003] With the increase in labor costs, the rapid development of the Internet of Things and visual technology, the new door gate machine market has ushered in a peak of development. On the one hand, the new door gate machine can replace security guards and ticket inspectors for security inspection work; People flow information has great prospects in the fields of offices, factories, construction sites, residences, and public transportation. Because the gate with small installation area an...
