How to set up Yuview car intrusion detection battery camera?

Program Requirements

1. Elevator safety hazard

Passenger elevators are designed and manufactured with people in mind. Forcibly driving cars with batteries will cause overload, bumps and bumps will damage service life of elevator and create a safety hazard.

2. Fire hazard

Charging battery cars indoors can easily start a fire, and maximum burning temperature can reach 1200 degrees. Some residents are not aware of fire safety measures.

3. Elevator resource consumption

During peak use of elevator during commuting, reduce number of people elevator can carry and increase waiting time for other users.

4. Difficulties in property management

The property can be seen but not tracked in time, and there are many buildings in community, it is difficult to fully secure property.

Network solution for Uniview cameras Uniview camera battery car detection algorithm

Battery car entrance detection: In designated area of ​​the elevator, when battery car enters area, an alarm will be generated when elevator entrance is detected. Battery car leaves area: When battery car at specified location leaves area, alarm will be restored.

Uniview camera installation requirements

Environmental requirementsElevator scene, sufficient fill light, fixed camera. Avoid serious car reflections and ghosting in multiple scenes.

Installation requirementsInstallation height is 2.5-4m, supported tilt angle is 30° to 80°, and optimum angle is 45°~75°. Installed in upper right corner of elevator so that body does not cover body.

Pixel requirementsOptimal detection target size range lower limit: 200 x 200 pixels, upper limit: 800 x 800 pixels (recommended (600, 400)

Uniview camera configuration

The battery car detection setting method requires logging into camera's web interface via a LAN computer to set up. The specific setting method is as follows:

Enable elevator entrance detection and draw detection area: [Device] - [Smart monitoring] - [Smart function] - [Elevator entrance detection] to enable elevator entrance detection function;< /strong>p>

Drawing detection rules. Enable discovery rules and you can set default sensitivity. Set detection target, size can be set

communication configuration

The specific method for setting arm lift control is as follows:

Linked alarm output: When camera is connected to stair control system, it needs to link alarm output and set up [Configuration>General alarm>Alarm output] according to actual stair control wiring ;

Linked sound and light alarms: When a detection is triggered, sound and light alarms can be linked, one of 3 warning sounds can be selected, as well as number of warning sounds and their duration. lights can be adjusted at same time;

Set arming schedule: check , camera will link alarm according to configured arming time

Elevator working principle with lock door Camera working principle:

1. There is a relay inside chamber (which can be equivalent to a switch), and [ALM_OUT+] and [ALM_OUT-] on tail wire can be shorted to appropriate elevator interface (the camera can be thought of as a wire).

2. Whether switch is "normally open" or "normally closed" by default is determined by software strategy and adjusted according to actual elevator wiring requirements.

Power supply requirements for peripheral loads:

AC: Voltage does not exceed 125VAC and current does not exceed 0.3A.

Constant Current: Voltage does not exceed 24VDC and current does not exceed 1A.

How to take elevator:

Consult lift manufacturer. The camera terminal is a passive switching signal. Whether this will affect operation of elevator or annual inspection of elevator should be assessed by relevant personnel.

Note. It is forbidden to access elevator for testing and use without permission of elevator manufacturer and relevant departments.

Ladder control connection method:

The elevator keeps door open and can be controlled in three ways: a light curtain, a safety touch panel, and a door open button. The security touchpad wiring is normally closed and door open button wiring is normally open. See wiring method for normally open and normally closed light curtain

When light curtain is normally closed, camera's alarm switch is normally open by default. At this time, you need to add a relay to reverse camera signal

When screen is normally open, camera's alarm switch is normally open by default. At this time, camera alarm output line can be directly connected to the circuit

Factors affecting recognition that door is not closed

Site survey does not meet requirements

Insufficient lighting in cockpit, inability to maintain full color; serious reflections on both sides of elevator, darkness inside elevator, a lot of interference and reflections; an advertising machine is exposed to a strong light on cabin wall

Recognition model without algorithm

Only battery car detection is supported, other cars are not supported. The rain cover of battery car can be purposefully identified, and severe overlap will affect detection effect

Configuration Exception

Elevator entrance detection is not enabled; drawing detection rule is too small, detection has false positives; detection blind zone does not cover all areas

The elevator won't close door

Algorithm misidentification causes link to not close door;
