Problems solved by technology

[0002] At present, most of the existing building entrance control systems use a single processor to handle all work tasks, and all tasks need to be queued and time-shared according to the priority level, which sometimes lags behind the response to sudden interruptions
And when too many tasks are triggered at the same time, there is a risk of being unable to respond to interruptions or even crashing
[0003] Moreover, when the processor of the existing system fails on site, it is impossible to determine which functional module has a problem, so the entire processor needs to be replaced
It is not conducive to on-site troubleshooting, and it will also bring additional maintenance costs to customers

Embodiment 1

[0030] Such as figure 1 As shown, a multiprocessor-based building entrance control system according to this embodiment includes a local main control board, and the local main control board includes peripheral sensors, buttons, motor control processors, a main controller, and motor.

[0031] Wherein the peripheral sensor and the button are used to send a trigger request to the main controller. The peripheral sensors include, but are not limited to, indoor and outdoor infrared sensors and / or indoor and outdoor radar sensors and / or door closing presence sensors and / or door opening edge presence sensors and / or key trigger sensors and / or emergency stop triggers The sensor and / or the door lock control triggers the sensor.

[0032] The motor control processor is used to drive the motor to run, measure the running state parameters of the motor in real time, and feed back the running state parameters to the main control processor through the bus. The number of the motor control proc...

Embodiment 2

[0044] Such as figure 2 As shown, in order to comply with a multiprocessor-based building entrance control method described in this embodiment, the method includes the following steps:

[0045] S1: Peripheral sensors and buttons send trigger requests to the main controller;

[0046] The motor control processor measures the operating state parameters of the motor, and feeds back the operating state parameters to the main control processor through the bus in real time;

[0047] S2: The main control processor monitors the running state parameters in real time and responds to the trigger request in real time, and sends a control command to the motor control processor;

[0048] S3: The motor control processor receives a control instruction from the main controller, and drives the motor to drive a device to execute the control instruction.

[0049] The number of the motor control processor and the motor can be one or more, and those skilled in the art can make corresponding setti...

Abstract

The invention discloses a multiprocessor-based building entrance control system and method. Multiple processors synergistically process respective work tasks, for a real-time control unit, especially, the accuracy in motor control is higher, and emergency responses can be processed quickly and efficiently. Meanwhile, a plurality of on-site main control boards can be arranged according to actual needs to achieve different functions respectively. Due to the modular design mode, system development risks and work task loads of all unit modules can be effectively reduced, and later-period corrective maintenance and maintenance cost reduction are facilitated. Moreover, as the on-site main control boards are mutually independent and have different address assignments, software upgrading can be conveniently performed on all the on-site main control boards through a bus at a later period.

Description

technical field [0001] The invention relates to the technical field of entrance control, in particular to a multiprocessor-based building entrance control system and a control method thereof. Background technique [0002] At present, most of the existing building entrance control systems use a single processor to handle all work tasks, and all tasks need to be queued and processed according to the priority level, which sometimes lags behind in responding to sudden interruptions. Moreover, when too many tasks are triggered at the same time, there is a risk of being unable to respond to interruptions or even crashing. [0003] Moreover, when the processor of the existing system fails on site, it is impossible to determine which functional module has a problem, so that the entire processor needs to be replaced. It is not conducive to on-site troubleshooting, and will also bring additional maintenance costs to customers. Contents of the invention [0004] The invention aims ...
