b) Pallet parking service mobile robot;
c) Wheel-clamp parking service mobile robot.
5 Technical requirements
5.1 Performance requirements
5.1.1 Design load requirements
According to the provisions of Chapter 5 in GB/T 26559-2011, cars are divided into 6 major groups: X (small), Z (medium), D (large), T (extra-large), C (ultra- large), K (bus). According to different application requirements, the designated group of cars is used as the applicable parking robot group of the parking robot. The design load of the parking robot shall be greater than or equal to 1.1 times the maximum mass of the applicable parking robot group.
5.1.2 Travel function
The parking robot shall be able to achieve all or part of the following omnidirectional motion functions:
a) Moving forward, the parking robot moves forward along the longitudinal The electrical design of the parking robot shall comply with the provisions of 6.7.7.3 in GB/T 30029-2013.
6 General safety requirements
6.1 Requirements for contact buffer protection and non-contact
protection
6.1.1 Overview
In the main running direction of the parking robot, it shall have either a contact buffer protection function or a non-contact protection function, to protect the safety of personnel and the parking robot.
6.1.2 Requirements for contact buffer protection
The contact buffer protection is mainly used when the parking robot is running at low speed, if the parking robot is traveling at a speed of not more than 0.3 m/s, the parking robot shall immediately stop moving and alarm when it hits the buffer. The parking distance shall be within the buffer range of the buffer. 6.1.3 Requirements for non-contact protection
The detection range of non-contact protection shall be larger than the maximum contour range of the robot and the car when the parking robot is carrying the car. When the parking robot detects a person or obstacle in the direction of travel, it shall automatically slow down and stop. The safety distance between the car and the obstacle at the final parking position shall be greater than 50 mm; when the person or obstacle is removed, the parking robot is required to issue a restart audible and visual alarm (3 s or more) before it can restart. When the parking robot is in motion, the detection function of the motion direction must not be turned off.
6.2 Anti-overlap automatic detection
In order to avoid parking the car into the parking space of the parked car, the parking robot shall be equipped with one or more detection devices of sound, light, electricity to detect the status of the parking space (there are no cars, car- carrying pallet or other objects that affect the parking), or take other anti- overlapping measures.
6.3 Emergency stop button
The design of the emergency stop function shall meet the requirements of GB/T 16754.
6.4 Manual mode requirements
c) Air: No dust, flammable, explosive and corrosive gas.
7.2 Ground requirements
The parking robot's requirements for ground conditions shall meet the
requirements of 5.1.5.
8 Test method
8.1 Performance requirements test
8.1.1 Load
The comprehensive performance test of the parking robot under the design load is as follows:
Randomly choose 5 parking spaces; simulate the position of the front and rear wheels of the car on the parking robot; apply the load according to the design load ratio of 6:4; complete 5 cycles of entry and exit. Each mechanism shall operate normally, without obvious deformation and abnormal noise; there is no damage to parking robots and cars; the position deviation accuracy meets the requirements of 5.1.3.
8.1.2 Traveling
Use manual mode to control the parking robot, to test whether the parking robot can complete all or part of moving forward, moving backward, moving
lateralward, turning around, spinning actions as expected.
8.1.3 Guidance and position deviation accuracy
Guidance deviation accuracy test: When the parking robot's motion reference point is at point P1, the parking robot starts from point P1 and travels straightly to point P2. The distance between point P1 and point P2 is not less than 5 m. Take the line connecting point P1 and P2 as the approximate theoretical straight- line running trajectory of the parking robot; according to the running trajectory and the contour size of the parking robot, mark the contour envelope edge of the parking robot running from point P1 to point P2 on the ground. As shown in Figure 1, put the cylindrical columns which have a diameter of 50 mm and a height of 500 mm on both sides of the parking robot's trajectory at an interval of 300 mm. The edge of the parking robot's contour envelope is 20 mm from the edge of the cylindrical column. When the parking robot runs back and forth between points P1 and P2 at the maximum operating speed without touching the cylindrical column, the test is qualified.
In the rated load and no-load conditions, the test is repeated 10 times each; if there is one failure, the test is considered to be failed.
parking space A. In the running stage when the parking robot moves the car to enter parking space A, the parking robot's anti-overlap automatic detection device shall be able to detect that a car has been parked in parking space A. At this time, the parking robot shall stop moving and send out a sound and light alarm.
8.2.4 Test of emergency stop function
For the running parking robot, after pressing down the emergency stop device, the parking robot shall be able to stop the movement and operation in the manner specified in GB/T 16754, without additional risks. After all emergency stop devices are manually reset, the parking robot can accept the restart function.
8.2.5 Test of alarm device performance
In the automatic operation state, confirm that the following various alarm devices are working properly:
a) Start indicator;
b) Operation indicator;
c) Fault indicator;
d) Sound and light alarm.
9 Inspection rules
9.1 Exit-factory inspection
Each parking robot shall be subject to exit-factory inspection by the
manufacturer in accordance with the standard; the contents of the exit-factory inspection shall meet the requirements of Table 1.
