1.使用svg实现组态画面和动态数据展示
通过js的定时器调用webservice方法获取数据后更新节点数据
/// <summary>启动定时刷新</summary>
function Start() {
InitSvgElement();
this.timer = setInterval("GetTagValues()", 1000);
}
/// <summary>启动定时刷新</summary>
function Stop() {
clearInterval(this.timer);
}
初始化svg的节点变量
/// <summary>初始化SVG元素</summary> function InitSvgElement() { this.svgDoc = document.getElementById('svgDoc').getSVGDocument(); this.svgRoot = this.svgDoc.documentElement; this.svg_jzwd = this.svgDoc.getElementById("tspan-jzwd"); this.svg_jzyl = this.svgDoc.getElementById("tspan-jzyl"); this.svg_czyl = this.svgDoc.getElementById("tspan-czyl"); this.svg_czwd = this.svgDoc.getElementById("tspan-czwd"); this.svg_yl = this.svgDoc.getElementById("tspan-yl"); this.svg_wd = this.svgDoc.getElementById("tspan-wd"); this.svg_yll = this.svgDoc.getElementById("rect-ylg"); }
通过ajax访问webservice
/// <summary>获取测点数据</summary> function GetTagValues() { try { $.ajax({ type: "POST", url: "../PsWebService.asmx/GetTagValues", data: { ip: ip, port: port, tagNames: tags }, dataType: 'xml', error: function (request) { alert("调用webService异常"); }, success: function (msg) { var tagValueJSON = $(msg).find("string").text(); UpdateTagLables(tagValueJSON); } }); } catch (e) { alert(e.Message); } }
更新节点变量的值
/// <summary>更新标签数据</summary> function UpdateTagLables(valueJSON) { var tagValueArray = eval('(' + valueJSON + ')'); if (tagValueArray.length != 6) { // alert("数据长度不足,请按照顺序设置测点!" + tagValueArray.length); return; } else { this.SetElementValue(this.svg_jzwd, tagValueArray[0].Value, " ℃"); this.SetElementValue(this.svg_jzyl, tagValueArray[1].Value, " MPa"); this.SetElementValue(this.svg_czwd, tagValueArray[2].Value, " ℃"); this.SetElementValue(this.svg_czyl, tagValueArray[3].Value, " MPa"); this.SetElementValue(this.svg_wd, tagValueArray[4].Value, " ℃"); this.SetElementValue(this.svg_yl, tagValueArray[5].Value, " MPa"); var yl = (tagValueArray[5].Value / 1000) * 68; //当前值除以量程(1000)得到百分比,然后乘以压力计的最大宽度得出实际应该显示的高度 yl = CurrencyFormatted(yl); this.svg_yll.setAttributeNS(null, "width", yl); } } /// <summary>设置元素值,数据进行格式化保留两位小数</summary> function SetElementValue(element, value, unit) { var newValue = CurrencyFormatted(value); if ($.browser.msie&&$.browser.version=="8.0") { //IE 下的写法 element.getFirstChild().setNodeValue(newValue + unit); } if ($.browser.msie && $.browser.version == "9.0") { //IE 下的写法 element.firstChild.textContent = newValue + unit; } if ($.browser.msie && $.browser.version == "10.0") { //IE 下的写法 element.firstChild.textContent = newValue + unit; } if ($.browser.chrome) { //Chrome下的写法 element.firstChild.textContent = newValue + unit; } else { element.firstChild.textContent = newValue + unit; } }
2.webservice方法调用pSpace的sdk类库获取数据
[WebMethod] public string GetTagValues(string ip, string port, string tagNames) { try { //\TestTag\mnl_1 List<PsPointValue> list = new List<PsPointValue>(); PsApi api = new PsApi(); api.Init(ip, port, "admin", "admin888"); if (api.Conn()) { PsPointValue ps = new PsPointValue(); string[] tagNameArray = tagNames.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries); list = api.GetDataSnapshot(tagNameArray); api.DisConn(); } return JsonConvert.SerializeObject(list); } catch (Exception ex) { return ex.Message; } }
