在本发明中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
传统的设备中多采用机械式压力表进行压力的测量、显示，机械式压力表通过表内的弹性敏感元件(波登管、膜盒或波纹管等)的弹性形变，再由表内机芯的转换机构将压力形变传导至指针，引起指针转动，在表盘上显示压力。然而，在实际应用场景中往往存在需要测量较高压力的情况，此时机械式压力表的量程较大，随着量程的增大，机械式压力表表盘中的每一个刻度表示的压力数值也就越大，机械式压力表的指针偏移带来的误差也随着变大，同时指针本身也在表盘中占了一定的幅度，人为的读数误差也会增大，并且指针的细微转动难以通过机械式压力表精准读取。
为此，本发明提出了一种汽车空调压力同步显示控制方法和系统，不同于传统的压力测量方法，本发明通过压力检测界面与机械式压力表同步显示压力值，能够提高压力检测的精确度和灵敏度，更加直观地展示压力值，并且通过压力检测界面与压力表的压力同步显示，能实时监测和反应真实的压力值，及时发现故障。
下面参照附图详细描述根据本发明实施例提出的一种汽车空调压力同步显示控制方法和 系统，首先将参照附图描述根据本发明实施例提出的一种压力同步显示控制方法。
参照图1，本发明实施例中提供一种汽车空调压力同步显示控制方法，本发明实施例中的一种汽车空调压力同步显示控制方法，可应用于终端中，也可应用于服务器中，还可以是运行于终端或服务器中的软件等。终端可以是平板电脑、笔记本电脑、台式计算机等，但并不局限于此。服务器可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是提供云服务、云数据库、云计算、云函数、云存储、网络服务、云通信、中间件服务、域名服务、安全服务、CDN、以及大数据和人工智能平台等基础云计算服务的云服务器。本发明实施例中的一种汽车空调压力同步显示控制方法主要包括以下步骤：
S101、根据待测点的形变，通过压力表显示第一压力值；
具体地，压力表为机械式压力表，机械式压力表将表内的敏感元件如波登管、膜盒或者波纹管等的弹性形变通过表内机芯的转换机构传导至指针，以此引起指针的转动，达到显示第一压力值的目的。
其中，所述待测点包括高压待测点和低压待测点，所述压力表包括高压压力表和低压压力表，所述第一压力值包括第一高压压力值和第一低压压力值，所述第一高压压力值为所述高压压力表显示的所述高压待测点的压力值，所述第一低压压力值为所述低压压力表显示的所述低压待测点的压力值。
S102、根据所述待测点的形变，通过传感器采集压力信号，所述压力信号为模拟信号；
具体地，所述传感器根据所述待测点发生的弹性形变产生相应的压力信号。
S103、响应于压力检测指令，显示第一提示界面；
其中，所述第一提示界面中包含第一确认指令发送指引，所述第一确认指令发送指引用于指引用户发送第一确认指令。
S103可以进一步划分为以下步骤S1031-S1033：
步骤S1031、确认高压管路和低压管路的阀门状态；
其中，所述阀门状态用于判断所述高压管路和所述低压管路与空调系统是否连通，所述高压管路为所述高压待测点所在的管路，所述低压管路为所述低压待测点所在的管路。
步骤S1032、若所述阀门状态为关闭，则进行所述高压管路和所述低压管路的压力补偿；
具体地，由于所述高压管路和所述低压管路在通过阀门与空调系统连通之前处于常压状态，而空调系统中含有高压状态的制冷剂，若直接打开阀门，会导致空调系统中的制冷剂由于压力差流入所述高压管路和所述低压管路，造成由于空调系统内的制冷剂减少带来的数据 失真。通过往所述高压管路和所述低压管路中注入制冷剂，达到空调系统中的制冷剂压力，从而完成压力补偿操作。
步骤S1033、所述第一提示界面提示执行所述发送第一确认指令的操作。
S104、响应于所述第一确认指令，显示第二提示界面；
其中，所述第二提示界面中包含第二确认指令发送指引，所述第二确认指令发送指引用于指引用户发送第二确认指令。
S104可以进一步划分为以下步骤S1041-S1043：
步骤S1041、确认所述阀门状态；
同步骤S1031所述，阀门开启时，所述高压管路和所述低压管路与所述空调系统连通，阀门关闭时，所述高压管路和所述低压管路与所述空调系统不连通。
步骤S1042、若所述阀门状态为开启，则确认所述空调系统的运行状态。
具体地，若所述阀门状态为开启，则所述空调系统与所述高压管路和所述低压管路连通；空调系统的运行状态包括正在运行和未运行，其中，运行状态为正在运行，使制冷剂在所述空调系统内实现液态与气态的相互转换，从而形成高压和低压之分；运行状态为未运行，则所述第二提示界面会等待空调系统开始运行，再执行下一步骤。
步骤S1043、若所述空调系统正在运行，则所述第二提示界面可执行发送第二确认指令。
具体地，根据步骤S1042所述，若所述空调系统正在运行，所述空调系统内已处于制冷剂的液态和气态相互转换阶段，此时可执行发送第二确认指令的操作，进入压力检测界面。
S105、响应于所述第二确认指令，显示压力检测界面；
其中，所述压力检测界面用于根据所述压力信号显示第二压力值。
具体地，所述第二压力值包括刻度压力值和数字压力值，所述刻度压力值与所述第一压力值的显示模式相同，所述压力检测界面同时显示所述待测点的刻度压力值和数字压力值。
其中，所述第二压力值包括第二高压压力值和第二低压压力值，所述第二高压压力值为所述压力检测界面显示的所述高压待测点的压力值，所述第二低压压力值为所述压力检测界面显示的所述低压待测点的压力值。因此，前述可在所述压力检测界面同时显示的刻度压力值和数字压力值包括所述第二高压压力值的刻度压力值和数字压力值，以及所述第二低压压力值的刻度压力值和数字压力值。
S105可以进一步划分为以下步骤S1051-S1053：
步骤S1051、通过所述传感器将所述压力信号发送给控制单元；
具体地，所述压力信号为模拟信号，所述传感器根据所述待测点发生的弹性形变产生相 应的压力信号，并将所述压力信号发送给控制单元。
其中，传感器，采用压电压力传感器、压阻压力传感器或电容式压力传感器，用于将所述待测点的弹性形变转化为相应的压力信号；
控制单元，采用微控制单元(MCU)，例如STM32F103 VBT6等，用于接收所述压力信号，并将压力信号转换为所述第二压力值。
步骤S1052、所述控制单元接收到所述压力信号后，将所述压力信号转换为所述第二压力值；
已在步骤S1051中说明，不再赘述。
步骤S1053、通过所述压力检测界面获取并显示所述第二压力值，所述第二压力值与所述第一压力值同步显示。
其中，第二压力值包括刻度压力值和数字压力值，所述刻度压力值与所述第一压力值的显示模式相同，为类似机械式压力表的指针表盘显示模式。
具体地，通过所述压力检测界面获取并显示所述刻度压力值；通过所述压力检测界面获取并显示所述数字压力值。其中，刻度压力值和数字压力值的同步显示在步骤S104中已说明，不再赘述。
如前所述，第一压力值为机械式压力表通过指针在表盘上显示的压力值，第二压力值为压力检测界面显示的数字压力值和刻度压力值。其中机械式压力表显示的第一压力值精确度较低，存在表盘和指针本身带来的误差以及人为读数上的误差，而压力检测界面显示的第二压力值精确度较高，通过传感器采集压力信号，对于压力变化的反应要更加灵敏，但是其工作状态没有机械式压力表稳定。若第一压力值与第二压力值相差较大，则说明机械式压力表和压力检测界面的其中之一出现故障。
